PART I

Item 1. Business.

General

We are a geographically diversified oil and gas services company focused on completion fluids and otherassociated products and services, production testing, wellhead compression, and selected offshore services including well plugging and abandonment, decommissioning, and diving, withdiving. We also have a concentratedlimited domestic exploration and production business. We are composed of five reporting segments organized into three divisions – Fluids, Offshore,Production Enhancement, and Production Enhancement.Offshore.

Our Fluids Division manufactures and markets certain clear brine fluids, additives, and other associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations both in the United States and in certain regions ofcountries in Latin America, Europe, Asia, the Middle East, and Africa. The Division also markets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry.non-energy markets.
Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies in the construction or decommissioning of offshore oil and gas production platforms and pipelines, and (3) diving services involving conventional and saturated air diving.
The Maritech segment is an oil and gas exploration, development, and production operation focused in the offshore, inland waters, and onshore U.S. Gulf Coast region. The Offshore Division’s Offshore Services segment performs a significant portion of the well plugging, abandonment, and decommissioning services required by Maritech.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides production testing services in many of the major oil and gas basins in the United States, as well asStates. In addition, the Production Testing segment has operations in certain onshore basins in regions in Mexico, Brazil, NorthernNorth Africa, the Middle East, and other internationalforeign markets.

The Compressco segment, primarily through its Compressco Partners, L.P. subsidiary, provides wellhead compression-based and other production enhancement services throughout mostmany of the onshore producing regions of the United States, as well as certain onshore basins in Mexico, Canada, Mexico,and certain countries in South America, Europe, Asia, and other international locations.
 
Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.
The Maritech segment is an oil and gas exploration, development, and production operation focused in the offshore and onshore U.S. Gulf Coast region. During 2011, Maritech sold approximately 95% of the proved reserves it owned as of December 31, 2010, and is seeking to sell its remaining oil and gas producing property interests. Maritech’s remaining operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells, facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division’s Offshore Services segment.

We continue to pursue a growth strategy that includes expanding our existing businesses, with the exception of Maritech, both through internal growth and acquisitions, domestically and internationally. For financial information for each of our segments, including information regarding revenues and total assets, see “Note Q – Industry Segments and Geographic Information” contained in the Notes to Consolidated Financial Statements.

Products and Services

Fluids Division

Liquid calcium chloride, calcium bromide, zinc bromide, zinc calcium bromide, sodium bromide, and similar products producedmanufactured by our Fluids Division are referred to as clear brine fluids (CBFs) in the oil and gas industry. CBFs are salt solutions that have variable densities and are used as weighting agents to control bottom holebottomhole pressures during oil and gas completion and workover operations. Although they are used in many types of wells, demand for CBFs are particularly importantis greater in offshore well operations due to the potentially greater formation sensitivity and the significantly greater investment necessary to drill and produce offshore, which carries a higher cost of error. CBFs are manufactured and distributed by ouroperations. Our Fluids Division sells CBFs and CBF additives to U.S. and foreign oil and gas exploration and production companies and distributes them to other companies that service customers in the oil and gas indust ry.industry.

Our Fluids Division provides both basic and custom-blended CBFs to U.S. and international oil and gas exploration and production companies based on theirour customers’ specific needs and the proposed application. We also provide a broad range of associated services, including onsite fluidfluids filtration, handling, and recycling; wellbore cleanup; fluid engineering consultation; and fluid management services,services; as well as high volumehigh-volume water transfer and treatment services for high pressure fracturing operations. We offer to repurchase (buyback) from customers used CBFs, which we are able to recondition and recycle. The utilization of reconditionedSelling used CBFs back to us reduces the net cost of the CBFs to our customers and minimizes the need to dispose of used fluids. We recondition theused CBFs through filtration, blending, and the use of proprietary chemical processes, and then market the reco nditionedreconditioned CBFs.

By blending different CBFs and using various additives, we are able to modify the specific density, crystallization temperature, and chemical composition of the CBFs as necessary. The Division’s fluid engineering personnel determine the optimal CBF blend for a customer’s particular application to maximize thetheir effectiveness and lifespan of the CBFs. We modify the specific density, crystallization temperature, and chemical composition of the CBFs as necessary.lifespan. Our filtration services use a variety of techniques and equipment for the removal ofto remove particulates from CBFs at the customer’s site, so they can be reused. Filtration also enables recovery of a greater percentage of used CBFs for reconditioning.

The Fluids Division manufactures liquid and dry calcium chloride, liquid calcium bromide, zinc bromide, zinc calcium bromide, and sodium bromide for distribution primarily into energy markets. Liquid and dry calcium chloride are also sold into the water treatment, industrial, cement, food processing, dust control,road maintenance, ice melt, agricultural, and consumer products markets. Liquid sodium bromide is also sold into the industrial water treatment markets, where it is used as a biocide in recirculated cooling tower waters and in other applications.

Our liquid and dry calcium chloride production facilities are located in the United States and Europe. We also acquire liquid and dry calcium chloride inventory from other sources, including non-owned plants under agreements with the owners.producers. Domestically, we manufacture calcium chloride at five manufacturing plant facilities, the largest of which is our plant near El Dorado, Arkansas. This plant was recently constructedArkansas, which produces liquid and began production of liquidflake calcium chloride during the fourth quarter of 2009 and dry (flake) calcium chloride during January 2010.products. Liquid and flake calcium chloride are also produced at our Kokkola, Finland, plant. We operate our European calcium chloride manufacturing operations under the name TETRA Chemicals Europe. As of December 31, 2010, we continued to operate a plant in Lake Charles, Louisiana,

However, in February 2011, we shut downmanufacturing operations under the dry (pellet) calcium chloride plant at this facility.name TETRA Chemicals Europe. We manufacture liquid calcium chloride at our facilityfacilities in Parkersburg, West Virginia, and Lake Charles, Louisiana, and we have two solar evaporation plants located in San Bernardino County, California, that produce liquid calcium chloride from underground brine reserves. All of our calcium chloride production facilities have a combined production capacity of more than 1.5 million liquid equivalent tons per year.

We manufacture and distribute calcium bromide, zinc bromide, zinc calcium bromide, and sodium bromide at our West Memphis, Arkansas, production facility. A patented and proprietary production process utilized at this facility uses bromine and zinc to manufacture zinc bromide. We purchase raw material bromine pursuant to a long-term supply agreement. This facility also uses proprietary processes to manufacture calcium bromide and sodium bromide and to recondition and upgrade used CBFs repurchased from our customers.

We also lease approximately 33,000 gross acres of bromine-containing brine reserves in Magnolia, Arkansas. We hold these assets for possible future development and to provide a security of supply for our bromine and other raw materials.

See “Note Q – Industry Segments and Geographic Information” in the Notes to Consolidated Financial Statements for financial information about this Division.

Offshore Division

Our Offshore Division consists of two separate operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea services such as well plugging and abandonment (P&A), workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies in the construction or decommissioning of offshore oil and gas production platforms, subsea wells, and pipelines, and (3) diving services involving conventional and saturated air diving. We provide these services to offshore oil and gas operators in the U.S. Gulf of Mexico and in the inland water and onshore markets in the U.S. Gulf Coast region. We offer comprehensive, integrated services, including individualized engineering consultation and project management services. The Maritech segment is an oil and gas exploration, development, and production company operating in the offshore, inland waters, and onshore U.S. Gulf Coast regions. The Offshore Division’s Offshore Services segment performs a significant portion of the P&A and decommissioning services required by Maritech, and Maritech is a significant customer of the Offshore Services segment.

In providing its services, our Offshore Services segment utilizes barge-mounted P&A rigs, a platform P&A rig, offshore rigless P&A packages, two heavy lift vessels, several dive support vessels and other dive support assets, and onshore rigs that we own and operate. In addition, we lease other assets from third parties and engage third-party contractors whenever necessary. The Offshore Services segment provides a wide variety of contract diving services to its customers through our subsidiary, Epic Diving & Marine Services (Epic). Well abandonment, decommissioning, and certain construction services are performed primarily offshore in the U.S. Gulf of Mexico, although the Offshore Services segment provides P&A services to customers in the inland waters and onshore in Texas and Louisiana. The Offshore Services segment p rovides onshore and offshore cutting services and tool rentals through its E.O.T. Cutting (EOT) operations. The Offshore Services segment’s electric wireline operation specializes in cased-hole logging, mechanical completion services, plugbacks, bridge plugs and packer services, pipe recovery (cased and open hole), perforating, and tubing-conveyed perforating services. The Offshore Services segment also utilizes the specialized equipment and engineering expertise necessary to address a variety of specific platform construction and decommissioning issues, including those associated with platforms toppled or severely damaged by hurricanes. The Offshore Services segment provides services to major oil and gas companies and independent operators, including Maritech, through its facilities located in Lafayette, Broussard, Harvey, and Houma, Louisiana and in Bryan and Victoria, Texas.

The size of our Offshore Services segment’s fleet of service vessels has expanded and contracted in recent years as necessary to serve the changing demand for well abandonment, construction, platform and pipeline decommissioning, construction, diving, and other offshore services. We currently have two vessels with the capacity to perform heavy lift decommissioning and construction projects and integrated operations on oil and gas production platforms. Subsequent to our acquisition of Epic in March 2006, we purchased a
3

dynamically positioned dive support vessel, the Epic Diver, and refurbished two of Epic’s existing dive support vessels, the Epic Explorer and the Epic Seahorse. The Epic Diver, which has been significantly utilized since we acquired it, has required extensive repair and refurbishment in the past and is currently in need of significant further repairs. In addition, certain of the Offshore Services segment’s more significant customers now require more technologically updated dive support vessels. In response to these changes, beginning in June 2009, we increased our service fleet by leasing a specialized dive support vessel, the Adams Challenge. In addition, the Offshore Services segment leases additional dive support vessels as they are needed. As a result, in December 2010, we determined that the Epic Diver is no longer strategic to our Offshore Services segment’s plans to serve its markets going forward, and a decision was made to divest the vessel. Each of the leased dive support vessels, as well as one of the Offshore Services segment’s owned dive support vessels, the Epic Explorer, includes a saturation diving system that is rated for up to 1,000 foot dive depths.

Among other factors, demand for our Offshore Service segment’s operations in the Gulf of Mexico is affected by federal regulations governing the abandonment and decommissioning of offshore wells and production platforms and pipelines, particularly following the April 2010 Macondo well oil spill. Recent regulations issued by the Bureau of Ocean Energy, Management, Regulation, and Enforcement (BOEMRE) have included Notice To Lessees  2010-G05: “Decommissioning Guidance for Wells and Platforms” (NTL 2010-G05, known as the “Idle Iron Guidance”), which requires that permanent plugs be set in nearly 3,500 nonproducing wells in the U.S. Gulf of Mexico and that approximately 650 oil and gas production platforms in the U.S. Gulf of Mexico be dismantled if they are no longer being used. The “Idle Iron Guidance&# 8221; became effective October 15, 2010, and requires that operators perform and report decommissioning and abandonment plans and activities in accordance with BOEMRE requirements. The NTL 2010-G05 regulations provide specific guidelines for the maximum time that an operator has to permanently plug and abandon wells and decommission platforms and related facilities upon the occurrence of certain events, including the end of useful operations, cessation of commercial production, and expiration of the lease.

Maritech is an oil and gas exploration and production operation with properties located in the offshore, inland water, and onshore U.S. Gulf Coast region. The Offshore Division’s Offshore Services segment performs a significant portion of the well abandonment and decommissioning services required by Maritech.

Maritech has historically grown its operations by acquiring and developing oil and gas property interests located in the offshore, inland waters, and onshore U.S. Gulf Coast region. However, due to efforts to conserve and reallocate capital, we have begun to decrease our investment in Maritech by suspending our search for oil and gas property acquisitions and decreasing our development activities. In addition, we are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and are reviewing opportunities to sell Maritech oil and gas property packages to industry participants and other third parties. As part of this overall effort, in February 2011, Maritech sold a group of properties that accounted for approximately 11.4% of its proved reserves as of December 31, 2010. Maritech continues to perform a significant amount of plugging, abandonment, and decommissioning work on its offshore oil and gas properties as part of its strategy to reduce its risk from hurricanes and in response to the high cost of windstorm insurance coverage. During the three year period ended December 31, 2010, Maritech has expended approximately $194.8 million on such efforts.

Maritech’s decommissioning liabilities are established based on what it estimates a third party would charge to plug and abandon the wells, decommission the pipelines and platforms, and clear the sites. Maritech’s decommissioning liabilities, as of December 31, 2010, total $265.5 million ($285.8 million undiscounted). We review the adequacy of Maritech’s decommissioning liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed materially. The timing and amounts of these cash flows are subject to changes in the energy industry environment and may result in additional liabilities to be recorded. As of December 31, 2010, Maritech determined that significant adjustments were necessary to increase its decommissioning liabilities to reflect current industry developments, including the impact from the NTL 2010-G05 “Idle Iron Guidance” issued in late 2010 by BOEMRE. For a further discussion of Maritech’s adjustments to its decommissioning liabilities, see “Note I – Decommissioning and Other Asset Retirement Obligations” in the Notes to Consolidated Financial Statements.

While Maritech’s exploration and development activities have been reduced during the past two years, Maritech has continued to develop certain of its most strategic property assets. Maritech’s mostsignificant development efforts are currently located on the East Cameron 328 block located in Federal offshore waters and the Timbalier Bay field located in the inland waters area of Louisiana. During 2010, Maritech participated in drilling eight wells, four of which were located in the Timbalier Bay field. Seven of the wells were successful. The most recent acquisitions of producing oil and gas properties were in July 2010, when Maritech purchased interests in certain onshore oil and gas properties located in McMullen County, Texas.

During the three year period ended December 31, 2010, Maritech invested approximately $182.4 million on exploration, exploitation, development, and acquisition activities, although such activities decreased beginning in 2009 due to capital spending constraints. As of December 31, 2010, Maritech had proved reserves of approximately 7.3 million barrels of oil and liquids, and 25.6 billion cubic feet of natural gas, with undiscounted future net pretax cash flow of approximately $210.0 million.

Production Enhancement Division

The Production Testing segment of the Production Enhancement Division provides post-frac flow back pressure and volumewell testing of onshoreservices. The segment provides well flow management and offshore oilevaluation services and gas wells, which provides reservoir data to enablethat enables operators to quantify reserves, optimize production, and minimize oil and gas reservoir damage. In addition to flow back and well testing, the Production Testing segment provides pipeline cleanout, well control, well cleanup, and laboratory analysis services. The Production Testing segment also provides early-life production solutions designed to accessfor newly available productionproducing oil and gas wells and provides late-life production enhancement solutions designed to boost and extend the productive life of oil and gas wells. Many of these services involve sophisticated evaluation techniques needed for reservoir management, including unconventional shale gasreservoir exploitation and optimization of well workover programs.

The Production Testing segment maintains one of the largest fleets of high pressure production testing equipment in the United States, including equipment designed to work in environments where high levels of hydrogen sulfide gas are present. The Production Testing segment has operating locations in Louisiana, Oklahoma, Pennsylvania, and throughout Texas. Internationally, the segment has locations in Mexico and South America, North Africa, the Middle East, and Asia.

During 2009, theThe Production Enhancement Division entered intoalso operates under a technical management contract to perform engineering, procurement, and installation of equipment needed for the cleanup and removal of oil bearing materials at two refinery locations in South America. The Division began providing services and equipment pursuant to this contract during late 2009 and throughout 2010. The remaining services to be provided under thethis contract are expected to continue to be performed in stages over the next two to three years.

The Division’s Compressco segment provides wellhead compression-based production enhancement services to a broad base of natural gas and oil exploration and production companies. These production enhancement services primarily consist of wellhead compression, related liquids separation, gas metering, and vapor recovery services. In certain circumstances, Compressco also provides ongoing well monitoring services and, in Mexico, automated sand separation services in connection with its primary production enhancement services. Virtually all of our Compressco segment’s operations are conducted through our subsidiary, Compressco Partners, L.P. (Compressco Partners), a Delaware limited partnership. We own approximately 83% of the outstanding ownership interest of Compressco Partners.

Although Compressco’s services are applied primarily to mature wells with low formation pressures, they are also employedutilized effectively on newer wells that have experienced significant production declines, orwells that are characterized by lower formation pressures.pressures, and in other applications. Compressco’s field services are performed by its highly trained staffs of regional service supervisors, optimization specialists, and field mechanics. In addition, Compressco designs and manufactures a majority of the compressor equipmentcompressors it uses to provide production enhancement services and in certain markets sells its compressor units to customers. Compressco’s fleet of compressor units totaled 3,6473,653 as of December 31, 2010,2011, of which 2,7112,941 units were in service, representing an increase in the number of units in service of approximately 2%8.5% from the prior year.

to allow wellbore liquids that would normally block gas flow (known as liquid loading) to produce up the wellbore.well. The liquids are separated from the gas stream and liquid-free gas flows into the GasJack® unit, where the gas is compressed. That gas is then cooled before being sent to the gas sales line. The separated fluids are either discharged to astored in an onsite customer-provided tank or reinjectedinjected into the gas sales line for separation downstream of the compressor. The gas is compressed, cooled and discharged into the sales line.downstream. The 46-horsepower GasJack® unit is an integrated power/compressor unit equipped with an industrial 460-cubic inch, V-8 engine that uses natural gas from the well to power one bank of cylinders that, in turn, powers the other bank of cylinders, which provide compression. Compressco recently introducedutilizes its 40-horsepower electric VJackTMcompressorTM compressor unit to provide its production enhancement services on wells located in larger, mature oil fields and in environmentally sensitive areas where electric power is available at the production site. TheIn addition Compressco uses its VJackTM compressor unit on oil wells or liquid-rich gas wells at both the early and late stages of their productive lives. Compressco believes that its VJackTM unit increasesprovides production uplift with zero engine-driven emissions and requires significantly less maintenance than a natural gas powered compressor. The VJackTM unit is primarily designed for vapor recovery applications (to capture natural gas vapors emitting from closed storage tanks after production and to reduce storage tank pressures) and backside pumping applications on oil wells.

Compressco utilizes its GasJack® and VJackTM units in conjunction with its personnel to provide compression services to its customers, primarily on a month-to-month basis. Compressco services its compressors and provides maintenance service on sold units through a staff of mobile field technicians who are based throughout Compressco’s market areas.

We offer comprehensive, integrated services, including individualized engineering consultation and project management services. The Maritech segment is an oil and gas exploration, development, and production operation in the offshore and onshore U.S. Gulf Coast region. During 2011, Maritech sold approximately 95% of its proved reserves. Maritech’s remaining operations consist primarily of the ongoing abandonment and decommissioning of its remaining offshore wells, facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division’s Offshore Services segment. In addition, Maritech is seeking to sell its remaining interests in oil and gas producing properties.

In providing services, our Offshore Services segment utilizes offshore rigless P&A packages, three heavy lift vessels, several dive support vessels and other dive support assets. In addition, we lease other assets from third parties and engage third-party contractors whenever necessary. The Offshore Services segment provides a wide variety of contract diving services to its customers through our subsidiary, Epic Diving & Marine Services (Epic). Well abandonment, decommissioning, and certain construction services are performed primarily offshore in the U.S. Gulf of Mexico. The Offshore Services segment provides onshore and offshore cutting services and tool rentals through its E.O.T. Cutting (EOT) operations. The Offshore Services segment’s electric wireline operation specializes in cased-hole logging, mechanical completion services, plugbacks, bridge plugs and packer services, pipe recovery (cased and openhole), perforating, and tubing-conveyed perforating services.

The size of our Offshore Services segment’s fleet of service vessels has expanded and contracted in recent years in response to the changing demand for its services. Including the new 1,600-metric-ton heavy lift derrick barge we purchased in July 2011, we currently have three vessels capable of performing heavy lift decommissioning and construction projects and integrated operations on oil and gas production platforms. In addition, the Offshore Services segment leases additional dive support vessels as they are needed. One of these leased vessels, the Adams Challenge, as well as one of the Offshore Services segment’s owned dive support vessels, the Epic Explorer, include saturation diving systems that are rated for up to 1,000-foot dive depths.

Among other factors, demand for our Offshore Service segment’s operations in the Gulf of Mexico is affected by federal regulations governing the abandonment and decommissioning of offshore wells, production platforms and pipelines, particularly following the April 2010 Macondo well oil spill. Regulations issued by the Bureau of Ocean Energy, Management, Regulation, and Enforcement (BOEMRE) include Notice To Lessees 2010-G05: “Decommissioning Guidance for Wells and Platforms” (NTL 2010-G05, known as the “Idle Iron Guidance”), which requires that permanent plugs be set in nearly 3,500 nonproducing wells in the U.S. Gulf of Mexico and that approximately 650 oil and gas production platforms in the U.S. Gulf of Mexico be dismantled if they are no longer being used. In October 2011, the BOEMRE’s responsibilities were divided between the Bureau of Ocean Energy Management (BOEM) and the Bureau of Safety and Environmental Enforcement (BSEE), which will oversee the provisions of the “Idle Iron Guidance”. The “Idle Iron Guidance” became effective October 15, 2010, and requires that operators perform and report decommissioning and abandonment plans and activities in accordance with BSEE requirements. The NTL 2010-G05 regulations provide specific guidelines for the maximum time that an operator has to permanently plug and abandon wells and decommission platforms and related facilities after the occurrence of certain events, including the end of useful operations, cessation of commercial production, and expiration of the lease.

The sales of almost all of Maritech’s oil and gas producing properties during 2011 have essentially removed us from the oil and gas exploration and production business, and all of Maritech’s significant oil and gas acquisition, development, and exploitation activities have ceased. During late 2010, we elected to explore strategic alternatives to our ownership of Maritech in order to conserve and reallocate capital to, and allow us to focus on, our remaining core businesses. As part of this strategic decision, beginning in February 2011, Maritech began selling oil and gas properties. Most significantly, in May 2011, Maritech sold approximately 79% of its proved oil and gas reserves as of December 31, 2010, to Tana Exploration Company LLC (Tana), a subsidiary of TRT Holdings, Inc., pursuant to a Purchase and Sale Agreement dated April 1, 2011. The sale was made for a base purchase price of $222.3 million. At the closing of the sale, Tana assumed approximately $72.7 million of associated asset retirement obligations, and Maritech received $173.3 million cash. In addition to the sale to Tana, Maritech sold other oil and gas property interests in separate transactions, with the most recent sale occurring in August 2011. Maritech is seeking to sell its remaining oil and gas property interests during 2012. Maritech continues to perform a significant amount of plugging, abandonment, and decommissioning work on its remaining offshore wells, facilites and production platforms as part of its strategy to reduce its risk from hurricanes. During the three year period ended December 31, 2011, Maritech has expended approximately $277.3 million on such efforts. Approximately $132.8 million of Maritech decommissioning liabilities remain as of December 31, 2011, and approximately $105.0 million of this amount is planned to be performed during 2012.

Maritech’s decommissioning liabilities are established based on what it estimates a third party would charge to plug and abandon the wells, decommission the pipelines and platforms, and clear the sites. We review the adequacy of Maritech’s decommissioning liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed materially. The timing and amounts of these cash flows are subject to changes in the energy industry environment and may result in additional liabilities being recorded. For a further discussion of Maritech’s adjustments to its decommissioning liabilities, see “Note I – Decommissioning and Other Asset Retirement Obligations” in the Notes to Consolidated Financial Statements.

Sources of Raw Materials

Our Fluids Division manufactures calcium chloride, calcium bromide, zinc bromide, zinc calcium bromide, and sodium bromide for distribution to its customers. The Division also recycles calcium and zinc bromide CBFs repurchased from its oil and gas customers.

The Division manufacturesproduces liquid calcium chloride, either from underground brine reserves or by reacting hydrochloric acid with limestone or from natural underground brine reserves.limestone. The Division also purchases liquid and dry calcium chloride from a number of U.S. and internationalforeign chemical manufacturers. Our El Dorado, Arkansas, plant produces liquid and flake calcium chloride, utilizing brine (tail brine) obtained from Chemtura Corporation (Chemtura) that contains calcium chloride. We also produce calcium chloride at our two plants in San Bernardino County, California, by solar evaporation of underground brine reserves that contain calcium chloride. These underground brine reserves are deemed adequate to supply our foreseeable need for calcium chloride at those plants.

The Division’s primary sources of hydrochloric acid are chemical co-product streams obtained from chemical manufacturers. Substantial quantities of limestone are also consumed when converting hydrochloric acid into calcium chloride. We use a proprietary process that permits the use of less expensive limestone, while maintaining end-use product quality. Currently, hydrochloric acid and limestone are generally available from multiple sources. We significantly increased our production capacity of liquid and dry calcium chloride with the construction of our El Dorado, Arkansas, c alcium chloride plant facility, which began production of liquid calcium chloride during the fourth quarter of 2009. This plant is located on land adjacent to a bromine plant of Chemtura Corporation (Chemtura), located near El Dorado, Arkansas. Our El Dorado, Arkansas, plant produces liquid and flake calcium chloride utilizing calcium chloride containing brines (tail brine) obtained from Chemtura’s operations, which allows the Division to reduce its dependence on third-party purchases of hydrochloric acid. We also produce calcium chloride at our two plants in San Bernardino County, California, by evaporating naturally occurring underground brine reserves that contain calcium chloride. These underground brine reserves are deemed adequate to supply our foreseeable need for calcium chloride at those plants.

We obtain raw materials utilized by our Lake Charles, Louisiana, facility to produce liquid and dry (pellet) calcium chloride from a variety of sources.sources to produce liquid calcium chloride. Due to our inability to obtain raw materials on an economic basis for this facility, during the fourth quarter of 2010 we determined that the future operating cash flows for the Lake Charles, Louisiana, facility were no longer adequate to support its carrying value and recorded an impairment of the net asset carrying value for this plant. In February 2011, we shut down the pellet plant operation at the Lake Charles, Louisiana, plant, although thehowever, we continue to produce liquid calcium chloride operation remains operational.at this plant when economically priced hydrochloric acid is available.

To produce calcium bromide, zinc bromide, zinc calcium bromide, and sodium bromide at our West Memphis, Arkansas, facility, we use bromine, hydrobromic acid, zinc, and lime.lime as raw materials. There are multiple sources of zinc that we can use in the production of zinc bromide and zinc calcium bromide. In December 2006, we entered intoWe have a long-term supply agreement with Chemtura, under which the Division purchases its requirements of raw material bromine from Chemtura’s Arkansas bromine facilities. In addition, we have a long-term agreement with Chemtura under which Chemtura supplies the Division’s new El Dorado calcium chloride plant with raw material tail brine from its Arkansas facilities following the extraction of bromine from such brine.facilities.

We also own a calcium bromide manufacturing plant near Magnolia, Arkansas, that was constructed in 1985. This plant was acquired in 1988 and is not operable. We currently lease approximately 33,000 gross acres of bromine-containing brine reserves in the vicinity of this plant. While this plant is designed to produce calcium bromide, it could be modified to produce elemental bromine or select bromine compounds. Development of the brine field, construction of necessary pipelines, and reconfiguration of the plant would require a substantial capital investment. The execution of thelong-term Chemtura bromine supply agreement discussed above provides us with an immediatea secure supply of bromine to support the Division’s current operations. We do, however, continue to evaluate our strategy related to the Magnolia, Arkansas, assets and their future development. Ch emturaChemtura holds certain rights to participate in any future development of the Magnolia, Arkansas, assets.

OurThe Production Testing segment of our Production Enhancement Division through its Production Testing segment, outsources the construction ofpurchases its production testing equipment toand components from third-party manufacturers. The Compressco segment designs and assembles the compressor units it uses to provide wellhead compression-based production enhancement services. Some of the components used in the assembly of compressor units and production testing equipment are obtained from a single supplier or a limited group of suppliers. We do not have long-term contracts with these suppliers and a partial or complete loss of certain of them could have a negative impact on our business.manufacturers. Should we experience unexpected unavailability of the components we use to assemble our equipment, we believe that there are adequate, alternative suppliers and that thisany impact would not be severe.

services to oil and gas exploration and production companies, onshore and offshore, in the United States and certain internationalforeign markets. Current areas of market presence include the onshore U.S., the U.S. Gulf of Mexico, the North Sea, Mexico, and certain countries in South America, Europe, Asia, the Middle East, and Africa. During the past two years, the Division’s U.S. operations have grown due to increased industry demand for frac water handling and treatment services in unconventional shale gas reservoirs. The Division also markets to customers with deepwater operations that utilize high volumes of CBFs and arecan be subject to harsh downhole conditions, such as high pressure and high temperatures. However, deepwaterDeepwater drilling activity in the U.S. Gulf of Mexico was significantly affected by the April 2010 well blowout of the Macondo well, which resulted in a temporary drilling moratorium in the deepwater Gulf of Mexico as well as a series of regulatory reforms associated with offshore oil and gas operations. While the deepwater drilling moratorium was lifted in October 2010, there remains significant regulatory uncertainty. In addition, government issuances of permits fora return to pre-Macondo offshore activities have slowed considerably, resulting inactivity levels has been slow due to many factors, including permitting and other delays in the timing for offshore projects, including projects forcontinuing regulatory uncertainty, and the focus by many of our customers.

In June 2008, we announced that we had signed a contract with Petroleo Brasileiro S.A. (Petrobras), the national oil company of Brazil, to provide completion fluids and associated servicesoperators on deepwater wells offshore Brazil. Through December 31, 2010, activity with Petrobras pursuant to this contract has also been much lower than anticipated.onshore opportunities.

The Division’s principal competitors in the sale of CBFs to the oil and gas industry are Baroid Corporation, a subsidiary of Halliburton Company; M-I Swaco, a subsidiary of Schlumberger Limited; and Baker Hughes, through its recently acquired BJ Services Company subsidiary.Hughes. This market is highly competitive, and competition is based primarily on service, availability, and price. Major customers of the Fluids Division include Anadarko, Devon, Dominion Resources, EOGDynamic Offshore Resources, Halliburton Company, LLOG Exploration, Newfield Exploration Company, NipponMarathon Oil, Exploration,Seneca Resources, Petrobras (the national oil company of Brazil), Shell Oil, Tullow Oil and Shell Oil.XTO Energy. The Division also sells its CBF products through various distributors worldwide.

Our liquid and dry calcium chloride products have a wide range of uses outside the energy industry. The non-energy market segments where these products are used include agricultural, industrial, roadway dust control androad maintenance, de-icing, mining, janitorial, construction, pharmaceutical, and food processing. We also sell sodium bromide into the industrial water treatment markets as a biocide under the BioRid® tradename. Most of these markets are highly competitive. The Division’s European calcium chloride manufacturing operations market our calcium chloride products to certain European markets. Our principal competitors in the non-
7

energynon-energy related calcium chloride markets include Occidental Chemical Corporation and Industrial del Alkali in North America, and Brunner Mond, Solvay, and NedMag in Europe.

Offshore Division

Our Offshore Division consists of our Offshore Services and Maritech segments. Long-term demand for the Offshore Services segment’s offshore well abandonment and decommissioning services is predominantly driven by the maturity and decline of producing fields in the Gulf of Mexico, aging offshore platform infrastructure, damage from storms, and government regulations. Demand for the Offshore Services segment’s construction and other services is driven by the general level of activity of its customers, which are also affected by oil and natural gas prices and the general economic condition of the industry.

Future demand for the services provided by our Offshore Services segment is expected to be increased as a result of the recent regulations issued by the BOEMRE, including NTL 2010-G05, the “Idle Iron Guidance.” In the U.S. Gulf of Mexico market, regulations generally require wells to be plugged, offshore platforms decommissioned, pipelines abandoned, and the well site cleared within twelve months after an oil or gas lease expires. However, NTL 2010-G05 establishes well abandonment and decommissioning requirements that are no longer tied to the one year anniversary of lease expiration. The maturity and production decline of Gulf of Mexico oil and gas fields has, over time, caused an increase in the number of wells to be plugged and abandoned and platforms and pipelines to be decommissioned.

Demand for offshore abandonment and decommissioning services during the past several years increased substantially as a result of 2005 and 2008 hurricane activity in the Gulf of Mexico, which destroyed or caused significant damage to a large number of offshore platforms and associated wells. While the vast majority of remediation work to be performed as a result of these storms has been performed, the Offshore Services segment continues to develop or acquire specialized equipment and engineering expertise that may be used to provide such services to customers whose offshore wells and production platforms were toppled, destroyed, or heavily damaged by storms or may be damaged by future storms. The threat of future storm activity, combined with the volatility of the cost of hurricane insurance premiums and associated deductibles, continues to accele rate the abandonment and decommissioning plans for undamaged wells and structures of many offshore operators.

Offshore activities in the Gulf of Mexico are highly seasonal, with the majority of work occurring during the months of April through October, when weather conditions are most favorable. Critical factors required to compete in the current market include, among other factors: an adequate fleet of the proper equipment; qualified, experienced personnel; technical expertise to address varying downhole, surface, and subsea conditions, particularly those related to damaged wells and platforms; the financial strength to ensure all abandonment and decommissioning obligations are satisfied; and a comprehensive safety and environmental program. During 2010, we acquired additional operating assets to supplement our existing equipment fleet, enabling us to expand our services, particularly those related to damaged wells and platforms. We believe our integrate d service package and vessel fleet satisfy these market requirements, allowing us to successfully compete.

The Offshore Services segment markets its services primarily to major oil and gas companies and independent operators. The Offshore Services segment’s most significant customer during the past two years has been Maritech. Other major customers include Apache, Chevron, Mariner Energy, Nexen Petroleum USA Inc., Stone Energy, Versabuild, and W&T Offshore. These services are performed primarily offshore in the U.S. Gulf of Mexico and in Gulf Coast inland waters and onshore in Texas and Louisiana, however, the segment is also seeking to expand its operations to international markets. Our principal competitors in the domestic offshore and inland water services markets are Global Industries, Ltd., Offshore Specialty Fabricators, Inc., Helix Energy Solutions, Cal Dive International, In c., and Superior Energy Services, Inc. This market is highly competitive, and competition is based primarily on service, equipment availability, safety record, and price. Our ability to acquire or lease suitable service vessels and other operating equipment is particularly important to our ability to serve our existing customers or to expand our operations to other markets. Our ability to successfully bid our services fluctuates from year to year, depending on market conditions.

Production Enhancement Division

The Production Enhancement Division provides production testing and wellhead compression-based production enhancement services and products to its customers. The Production Testing segment provides services primarily to the natural gas segment of the oil and gas industry. In certain gas producing basins, water, sand, and other abrasive materials commonly accompany the initial production of natural gas, often under high pressure and high temperature conditions and in some cases in reservoirs containing high levels of hydrogen sulfide gas. The Division provides the specialized equipment and qualified personnel to address these impediments to production. In addition, the Production Testing segment provides certain services designed to accommodate the unique flow back and testing demands of shale gas reservoirs. During the past two years, the Production Testing segment has expanded its equipment fleet to serve the rapidly growing demand for services associated with many of the domestic shale gas reservoirs, including the Marcellus, Barnett, Eagle Ford, Fayetteville, Woodford, and Haynesville basins. The Production Testing segment also provides early-life and late-life production enh ancementenhancement solutions designed to boost and extend the productive life of oil and gas wells.

The U.S. production testing market is highly competitive, and competition is based on availability of equipment and qualified personnel, as well as price, quality of service, and safety record. We believe our equipment, skilled personnel, operating procedures, and safety record give us a competitive advantage in the marketplace. The Production Testing segment is also committed to growing its international operations in order to serve most major oil and gas markets worldwide. The segment is seeking to grow its international operations,worldwide, both organically and through strategic acquisitions. Competition in onshore U.S. markets is primarily dominated by numerous small, privately owned operators. Schlumberger Limited, Weatherford International Oilfield Services, Halliburton, and Expro International are major competitors in the U.S. offshore market and interna tional markets.international markets we serve. The major customers for this segment include BP,BHP Billiton, Cabot, Chesapeake, ConocoPhillips, Encana Oil & Gas, Geosouthern Energy, Halliburton Company, Shell Oil, Southwestern Energy, PEMEX (the national oil company of Mexico), Petrobras, Saudi ARAMCO (the national oil company of Saudi Arabia), and other national oil companies in foreign countries.

The Division’s Compressco segment provides wellhead compression-based production enhancement services to over 400 natural gas and oil exploration and production companies operating throughout mostmany of the onshore producing regions of the United States. Internationally, Compressco also has significant operations in CanadaMexico and MexicoCanada and a growing presence in certain countries in South America, Eastern Europe, and the Asia-Pacific region. While most of Compressco’s domestic services are performed in the Ark-La-Tex region, San Juan Basin, and Mid-Continent region of the United States, it also has a substantial presence in other U.S. producing regions, including the Permian Basin, North Texas, Gulf Coast, Central and Northern Rockies, and California. Compressco has historically focused on serving customers with conventional production in mature fields, but it also services customers in some of the largest and fastest growing unconventional shale gas resource markets in the United States, including the Cotton Valley Trend, Barnett Shale, Fayetteville Shale, Woodford Shale, Piceance Basin, and Marcellus Shale. Compressco continues to seek opportunities to further expand its operations into other regions in the Western Hemisphere and elsewhere in the world.

The wellhead compression-based production enhancement services business is highly competitive, and competition primarily comes from various local and regional companies that utilize packages consisting of a screw compressor with a separate engine driver or a reciprocating compressor with a separate engine driver. To a lesser extent, Compressco faces competition from large national and multinational companies that have traditionally focused on higher-horsepower natural gas gathering and transportation equipment and services. Many of Compressco’s competitors attempt to compete on the basis of price. Compressco believes that its pricing is competitive because of the significant increases in the value of natural gas wells that result from the utilizationuse of its services. Compressco’s major customers include BP, PEMEX, Devon, EXCO Resource s,Resources, and ConocoPhillips.

Offshore Division

Our Offshore Division consists of our Offshore Services and Maritech segments.

The maturity and production decline of Gulf of Mexico oil and gas fields continues to cause an increase in the number of wells to be plugged and abandoned and platforms and pipelines to be decommissioned.

Offshore abandonment and decommissioning activity was high during the past several years as a result of 2005 and 2008 hurricanes in the Gulf of Mexico, which destroyed or caused significant damage to a large number of offshore platforms and associated wells. While the vast majority of this activity has been performed, it provided the Offshore Services segment the opportunity to develop and acquire specialized equipment and engineering expertise that may be used to provide such services to customers whose offshore wells and production platforms may be damaged by future storms. The threat of future storm activity, combined with the volatility of hurricane insurance premiums and associated deductibles, continues to accelerate the abandonment and decommissioning plans for undamaged wells and structures of many offshore operators.

Offshore activities in the Gulf of Mexico are highly seasonal, with the majority of work occurring during the months of April through October when weather conditions are most favorable. Critical factors required to compete in this market include, among other factors: an adequate fleet of the proper equipment; qualified, experienced personnel; technical expertise to address varying downhole, surface, and subsea conditions, particularly those related to damaged wells and platforms; and a comprehensive health, safety and environmental program. In July 2011, our Offshore Services segment purchased a new heavy lift derrick barge (which we have named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. The vessel was purchased from Wison (Nantong) Heavy Industry Co., Ltd. and Nantong MLC Tongbao
8

Shipbuilding Co., Ltd. for $62.8 million, subject to certain adjustments. The TETRA Hedron was transported to the Gulf of Mexico during the third quarter of 2011 and placed into service during the fourth quarter of 2011, following final outfitting and sea trials. During 2010, we also acquired additional operating assets to supplement our existing equipment fleet, enabling us to expand our services, particularly those related to damaged wells and platforms. We believe our integrated service package and vessel and equipment fleets satisfy the market requirements in the U.S. Gulf of Mexico, and allow us to successfully compete.

The Offshore Services segment markets its services primarily to major oil and gas companies and independent operators. The Offshore Services segment’s most significant customer during the past two years has been Maritech, and the majority of the remaining Maritech work to be performed for Maritech is planned to be performed during 2012. Other major customers include Apache, Chevron, Mariner Energy, Nexen Petroleum USA Inc., Stone Energy, Versabuild, and W&T Offshore. The Offshore Services segment’s services are performed primarily offshore in the U.S. Gulf of Mexico, however, the segment is also seeking to expand its operations to international markets. Our principal competitors in the U.S. Gulf of Mexico market are Technip USA (formerly Global Industries, Ltd.), Offshore Specialty Fabricators, Inc., Cal Dive International, Inc., and Superior Energy Services, Inc. This market is highly competitive, and competition is based primarily on service, equipment availability, safety record, and price. Our ability to acquire or lease suitable service vessels and other operating equipment is particularly important to our ability to serve our existing customers and to expand our operations to other markets.

In addition to shipping products directly from its production facilities in the United States and Europe, the Division has distribution facilities strategically located to provide efficient product distribution.

None of our customers individually exceeded 10% of our total consolidated revenues during the year ended December 31, 2010.2011.

Backlog

The level ofOur backlog is not indicative of our estimated future revenues, because a majority of our products and services either are not sold under long-term contracts or do not require long lead times to procure or deliver. Our backlog consists of estimated future revenues associated with a portion of our well abandonment and decommissioning business and consistsconsisting of the non-Maritech share of the well abandonment and decommissioning work associated with the remaining oil and gas properties operated by Maritech. Prior toFollowing the impact of any future sales of Maritech oil and gas properties during 2011, our estimated backlog on December 31, 20102011 was $64.1$11.6 million, the majority of which approximately $7.6 million is expected to be billed during 2011.2012. This compares to an estimated backlog of $121.9$64.1 million at December 31, 2009.2010.

Employees

As of December 31, 2010,2011, we had 2,9323,125 employees. None of our U.S. employees are presently covered by a collective bargaining agreement other than the employees of our Lake Charles, Louisiana, calcium chloride production facility, who are represented by the United Steelworkers Union. Our internationalforeign employees are generally members of the various labor unions and associations common toin the countries in which we operate. We believe that our relations with our employees are good.

Patents, Proprietary Technology, and Trademarks

As of December 31, 2010,2011, we owned or licensed twenty-onetwenty-two issued U.S. patents and had teneleven patent applications pending in the United States. Internationally, we had fifteensixteen owned or licensed foreign patents and fivetwenty-five foreign patent applications pending. The foreign patents and patent applications are primarily foreign counterparts to U.S. patents or patent applications. The issued patents expire at various times through 2028. We have elected to maintain certain other internally developed technologies, know-how, and inventions as trade secrets. While we believe that the protection of our patents and trade secrets is important to our competitive positions in our businesses, we do not believe any one patent or trade secret is essential to our success.

It is our practice to enter into confidentiality agreements with key employees, consultants, and third parties to whom we disclose our confidential and proprietary information and we have typical policies and procedures designed to maintain the confidentiality of such information. There can be no assurance, however, that these measures will prevent the unauthorized disclosure or use of our trade secrets and expertise or that others may not independently develop similar trade secrets or expertise. Our management believes, however, that it would require a substantial period of time and substantial resources to independently develop similar know-how or technology.

We sell various products and services under a variety of trademarks and service marks, some of which are registered in the United States or certain foreignother countries.

Health, Safety, and Environmental Affairs Regulations

We are subject to various federal, state, local, and internationalforeign laws and regulations relating to occupational health, and safety, and the environment, including regulations and permitting forregarding air emissions, wastewater and stormwater discharges, and the disposal of certain hazardous and nonhazardous wastes,wastes. Compliance with laws and wetlands preservation.regulations may expose us to significant costs and liabilities and cause us to incur significant capital expenditures in our operations. Failure to comply with these occupational health, safety, and environmental laws and regulations or associated permits may result in the assessment of fines and penalties and the imposition of investigatory and remedialother obligations.

With respect to ourOur operations in the United States various environmental protection laws and regulations have been enacted and amended in the U.S. during the past three decades in response to public concerns pertaining to the environment. Our U.S. operations and its customers are subject to these various evolving environmental laws and corresponding regulations. In the United States, these laws and regulations that are enforced by the U.S. Environmental Protection Agency (EPA); the BOEMREBSEE of the U.S. Department of the Interior; the U.S. Coast Guard; and various other federal, state, and local environmental authorities. Similar laws and regulations, designed to protect the health and safety of our employees and visitors to our facilities, are enforced by the U.S. Occupational Safety and Health Administration (OSHA), and other state and local agencies a ndand authorities. We must comply with the requirements ofSpecific environmental laws and regulations applicable to our operations includinginclude the Federal Water Pollution Control Act of 1972; the Resource Conservation and Recovery Act of 1976 (RCRA); the Clean Air Act of 1977; the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA); the Superfund Amendments and Reauthorization Act of 1986 (SARA); the Federal Insecticide, Fungicide, and Rodenticide Act of 1947 (FIFRA); the Toxic Substances Control Act of 1976 (TSCA); the Hazardous Materials Transportation Act of 1975; and the Pollution Prevention Act of 1990.

Our operations outside the United States are subject to various internationalforeign governmental controlslaws and restrictions pertainingregulations relating to the environment, occupational health and safety, and other regulated activities in the countries in which we operate. We believe that our operations are in substantial compliance with existing internationalforeign governmental controlslaws and regulations and that compliance with these international controlsforeign laws and regulations has not had a material adverse effect on operations.

At some of our facilities, we hold various permits regulating air emissions, wastewater and stormwater discharges, the disposal of certain hazardous and nonhazardous wastes, and wetlands preservation.

We believe that our manufacturing plants and other facilitiesoperations are in generalsubstantial compliance with all applicable health, safety, and environmental laws and regulations. Since our inception, we have not had a history of any significant fines or claims in connection with environmental or health and safety matters. We are committed to conducting all of our operations under the highest standards of safety and respect for the environment. However, risks of substantial costs and liabilities are inherent in certain plant and service operations and in the development and handling of certain products and equipment produced or used at our plants, well locations, and worksites. Because of these risks, there can be no assurance that significant costs and liabilities will not be incurred in the future. Changes in environmental and health and safety regulations coul dcould subject us to more rigorous standards. We cannot predict the extent to which our operations may be affected by future regulatory and enforcement policies.

On December 15, 2009, the EPA published its final findings that emissions of carbon dioxide, methane and other “greenhouse gases” present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth’s atmosphere and other climatic changes. These findings allow the EPA to adopt and implement regulations that would restrict emissions of greenhouse gases under existing provisions of the federal Clean Air Act. Accordingly, the EPA has adopted regulations that would require a reduction in emissions of greenhouse gases from motor vehicles and could trigger permit review for greenhouse gas emissions from certain stationary sources. In addition, on October 30, 2009, the EPA published a final rule requiring the reporting of greenhouse gas emissions from specified large greenhouse gas emission sources in the United States beginning in 2011 for emissions occurring in 2010. On November 8, 2010, the EPA finalized regulations to expand the existing greenhouse gas monitoring and reporting rule to include onshore and offshore oil and natural gas production facilities and onshore oil and gas processing, transmission, storage, and distribution facilities. Reporting of greenhouse gas emissions from such facilities would be required on an annual basis, with reporting beginning in 2012 for emissions occurring in 2011. The EPA’s rules relating to emissions of greenhouse gases from large stationary sources of emissions are currently subject to a number of legal challenges, but the federal courts have thus far declined to issue any injunctions to prevent EPA or state environmental agencies from implementing the rules. Further, Congress has considered, and almost one-half of the states have adopted, legislation that seeks to control or reduce emissions of greenhouse gases from a wide range of sources.

Offshore Operations

During 2010, the U.S. federal government established the BOEMRE to replace the U.S. Minerals Management Service (MMS). This federal agency reorganization was largely in response to the April 2010 blowout of the Macondo well and resulting oil spill in the Gulf of Mexico. The U.S. federal government imposed a drilling moratorium in the deepwater Gulf of Mexico that extended until October 2010. BOEMRE has also issued formal Noticeseveral Notices to Lessees (NTLs) and other safety regulations implementing additional safety and certification requirements applicable to drilling activities in the Gulf of Mexico, that have resulted in operations and projects being delayed or suspended. Such noticesThese NTLs and regulations issued to date include requirements by operators to:
 
·  Submitsubmit well blowout prevention measures and contingency plans, including demonstrating access to subsea blowout containment resources;
 
·  Abideabide by new permitting standards requiring detailed, independently certified descriptions of well design, casing, and cementing;
 
·  Followfollow new performance-based standards for offshore drilling and production operations;

We maintain various types of business insurance intended to mitigate our liabilityreimburse certain costs in the event of an explosion or similar event involving Maritech’s offshore operations. Our insurance program is reviewed not less than annually with our insurance brokers and underwriters. As part of our insurance program for offshore operations, we maintain general liability and protection and indemnity policies that provide third-party liability coverage, up to applicable policy limits, for risks of accidental nature, including but not limited to death and personal injury, full collision, liability, damage to fixed and floating objects, pollution, liability, and wreck removal. We also maintain a vessel pollution liability policy that provides pollution coverage for oil or hazardous subs tancessubstance pollution emanating from a vessel, addressing both OPA (Oil Pollution Act of 1990) and CERCLA obligations. This coveragepolicy also provides coverage for cost of defense, fines, and penalties. The Maritech energy insurance package provides operational all risks coverage (excluding named windstorm coverage) for physical loss or damage to scheduled offshore property, including removal of wreck and/or debris, and for operator’s extra expense such as control of well, redrill/extra expense, and pollution and cleanup.

Apart from our Maritech operations, we provide services and products to customers in the offshore Gulf of Mexico, generally pursuant to written master services agreements that create insurance and indemnity
11

obligations for both parties. If there was an explosion or similar catastrophic event on an offshore location where we are providing services and products, under the majority of our master services agreements with our customers:

(1)      We would be required to indemnify our customer for any claims for injury, death, or property loss or destruction made against them by us or our subcontractors or our or our subcontractor’s employees. The customer would be required to indemnify us for any claims for injury, death, or property loss or destruction made against us by the customer or its other subcontractors or the employees of the customer or its other subcontractors. These indemnities are intended to apply regardless of the cause of such claims, including but not limited to, the negligence of the indemnified party. Our insurance is structured to cover the cost of defense and any resulting liability from all indemnified claims, up to policy limits.

(2)      The customer would be required to indemnify us for all claims for injury, death, or property loss or destruction made against us by a third party that arise out of the catastrophic event, regardless of the cause of such claims, including but not limited to, our negligence or our subcontractors’ negligence. Our insurance is structured to cover the cost of defense and any resulting liability from all such claims; however, our insurance would be applicable to the claim only if the customer defaulted or otherwise breached its indemnity obligations to us.

(3)      The customer would be required to indemnify us for all claims made against us for environmental pollution or contamination that arise out of the catastrophic event, regardless of the cause of such claims, including our negligence or the negligence of our subcontractors. Our insurance is structured to cover the cost of defense and any resulting liability from all such claims; however, our insurance would be applicable to the claim only if the customer defaulted or otherwise breached its indemnity obligations to us.

Following the 2011 sales of the significant majority of Maritech’s offshore producing properties, we no longer participate in offshore drilling activities. However, Maritech engagesand our Offshore Services segment engage contractors to provide drilling and related services and products and well abandonment and related services and products on Maritech’s remaining offshore oil and gas production platforms and associated wells, generally pursuant to written master services agreements that create insurance and indemnity obligations for both parties. If there was an explosion or similarenvironmental event on an offshore Maritech location where a Maritech contractor was providing services and products, under a majority of Maritech’s master services agreements with its contractors, Maritech would be required to indemnify its contractor for any claims against the contractor for injury, death, or property loss or destruction brought by Maritech, its other subcontractors or their respective employees. The contractor would be required to indemnify Maritech for any claims for injury, death, or property loss or destruction made against Maritech by the contractor or its subcontractors or the employees of the contractor or its subcontractors. These indemnities would apply regardless of the cause of such claims, including the negligence of the indemnified party. Maritech’s insurance is structured to cover the cost of defense and any resulting liability from all indemnified claims, up to policy limits.

In accordance with applicable regulations, Maritech maintains an oil spill response plan with the BOEMRE,BSEE and has designated employees who are trained as qualified individuals and prepared to coordinate a response to any spill or leak. Maritech also has contracts in place to assure that a complete and experienced resource team is available as required.

Certain Business Risks

Although it is not possible to identify all of the risks we encounter, we have identified the following significant risk factors that could affect our actual results and cause actual results to differ materially from any such results that might be projected, forecasted, or estimated by us in this report.

Market Risks

The demand and prices for our products and services are affected by several factors, including the general economic, financial, business, political,supply, demand, and social conditions in the markets we serve or hope to serve in the futureprices for oil and natural gas.

The demandDemand for our products and services is materially dependent on the supply, demand, and prices for oil, natural gas, and competing energy sources, and more specifically dependent on the supply, demand, and prices for the products and services we offer, both in the United States and in the foreign countries in which we operate. These factors are also influenced by the regional economic, financial, business, political, and social conditions within the markets we serve or hope to serve, as well as the nationalU.S. and internationalforeign economic, financial, business, political and social conditions that impact the supply, demand, and prices of oil and gas. Activity levels have decreased as a result of the recent decline in energy consumption caused by the recent global recession. Decreased energy consumption has resulted in a decrease in energy price s, particularly natural gas prices, during much of 2010 compared to prices received during early to mid-2008. This decline in energy prices has negatively affected the operating cash flows and capital plans of many of our customers, which has negatively impacted the demand for many of our products and services.

If economic conditions worsen, there may be additional constraints on oil and gas industry spending levels. Such a stagnation of economic activity would negatively affect both the demand for many of our products and services as well as the prices we charge for these products and services, which would continue to negatively affect our revenues and future growth.

During times when oil or natural gas prices are low, many of our customers are more likely to experience a downturn in their financial condition. Economic conditions may also lead to additional constraints on the operating cash flows of our customers, potentially impacting their ability to pay us in a timely manner, which could result in increased customer bankruptcies and may lead to increased uncollectible receivables.

The demand for our products and services in the Gulf of Mexico could continue to be adversely impacted by the 2010 Macondo blowout and resulting oil spill, which has led to increased regulation and continuing regulatory uncertainty.

On April 20, 2010, a blowout on the Macondo well resulted in the rig catching fire and sinking. The resulting government-imposed drilling moratorium in the deepwater Gulf of Mexico and related regulatory requirements have significantly reduced the U.S. Gulf of Mexico completion fluids market and slowed the permitting of new drilling activity and plug and abandonment work in the U.S. Gulf of Mexico. The BOEMRE has issued several new regulations that are focused on offshore operating requirements, spill cleanup and enforcement matters. The BOEMRE recently issued to U.S. Gulf of Mexico operators notices implementing additional safety and certification requirements applicable to drilling activities in the Gulf of Mexico that have resulted in operations and projects being curtailed or suspended. Although the moratorium was lifted in October 2010, the b acklog of permits waiting to be issued for operations in the shallow water, for both new drilling and plug and abandonment work, and regulatory uncertainty regarding the deepwater activities did,
14

and are expected to continue to, negatively affect our Fluids Division and, to a lesser extent, our Offshore Services segment. Although we are unable to predict the full continuing impact of these factors on future operating results going forward, we expect our offshore activity levels and the offshore activity levels of our Fluids Division customers to be less than they were prior to April 2010.

In addition, we cannot predict how government regulatory agencies will further respond to the 2010 Macondo well incident or whether additional changes in laws and regulations concerning operations in the U.S. Gulf of Mexico will be enacted. Future regulatory requirements could further delay our customers’ activities, reduce our revenues, and increase our operating costs, including the cost to insure offshore operations, resulting in reduced cash flows and profitability.

Our oil and gas revenues and cash flows are subject to oil and gas price volatility.

Our revenues from the sale of oil and gas production represent approximately 23.1% of our total consolidated revenues for the year ended December 31, 2010. Therefore, we have significant direct market risk exposure in the pricing of our oil and gas production. Our realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot prices in the U.S. natural gas market and by the fixed prices in our derivative contracts for the portion of our oil and gas production that is hedged. During 2010, the crude oil and natural gas prices we received averaged $79.01 and $4.57, respectively, prior to the impact of our derivative contracts. Prices for crude oil and natural gas have historically been volatile, and such volatility is expected to continue. Significant declines in prices for oil and natural gas could have a material adve rse effect on our results of operations and quantities of reserves recoverable on an economic basis.

Our risk management activities include the use of derivative financial instruments, such as swap agreements, to hedge the impact of market price risk exposures for a portion of our oil and gas production. A portion of our production is sold at a fixed price that is intended to protect us from price declines that could occur in the market. These hedging activities also limit our upside potential from oil and gas price increases. We are exposed to the volatility of oil and gas prices for the portion of our oil and gas production that is not hedged. Currently, we do not have any natural gas derivative swap contracts in place, and our crude oil derivative swap contracts do not extend beyond December 31, 2011.

Oil and gas prices and, therefore, the levels of well drilling, completion, workover, and production activities, tend to fluctuate. Worldwide military,economic, political, and economic  events, including initiatives by the Organization of Petroleum Exporting Countries and increasing or decreasing demand in other large world economies, have contributed to, and are likely to continue to contribute to, price volatility. The expansion of alternative energy supplies that compete with oil and gas, improvements in energy conservation, and improvements in the energy efficiency of vehicles, plants, equipment, and devices will also reduce oil and gas consumption or slow its growth.

In particular, U.S. natural gas prices have been negatively affected by overall reduced energy demand in the U.S. due to economic conditions and weather, and the increase in natural gas supplies from shale gas drilling. This decline in natural gas prices has negatively affected the operating cash flows and exploration and development activities and plans of many of our customers, and could have a negative impact on the demand for many of our products and services.

Although the overall global economy has largely recovered from the 2008 recession, significant economic uncertainty remains. If economic conditions or energy prices deteriorate, there may be additional constraints on oil and gas industry spending levels. Reduced spending levels would negatively impact the demand for many of our products and services and the prices we charge for these products and services, which would negatively affect our revenues and future growth.

During times when oil or natural gas prices are low, many of our customers are more likely to experience a downturn in their financial condition. Poor economic conditions may also lead to additional constraints on the operating cash flows of our customers, potentially impacting their ability to pay us in a timely manner, which could result in increased customer bankruptcies and uncollectible receivables.

The demand for our products and services in the Gulf of Mexico could continue to be adversely impacted by increased regulation and continuing regulatory uncertainty.

Since the April 20, 2010, blowout on the Macondo well, operations in the U.S. Gulf of Mexico have been affected by an increased regulatory environment. The resulting federal regulatory requirements have significantly reduced the U.S. Gulf of Mexico completion fluids market. Although permitting levels increased somewhat during 2011, the pace of approvals for new drilling activity and plug and abandonment work in the Gulf of Mexico lags pre-Macondo levels. The BOEMRE issued several regulations, including notices to U.S. Gulf of Mexico operators, which are focused on offshore operating requirements, spill cleanup and enforcement matters. These regulations also implement additional safety and certification requirements applicable to drilling activities in the Gulf of Mexico that have resulted in operations and projects being curtailed or suspended. Although a drilling moratorium that was issued immediately following the Macondo blowout was lifted in October 2010, the backlog of permits waiting to be issued for operations in the shallow water for both new drilling and plug and abandonment work, and regulatory uncertainties regarding the deepwater activities are expected to continue to negatively affect our Fluids Division and, to a lesser extent, our Offshore Services segment. Although we are unable to predict the full continuing impact of these factors
14

on future operating results going forward, we expect our offshore activity levels and the offshore activity levels of our Fluids Division customers to continue to be less than they were prior to April 2010. Future regulatory requirements could further delay our customers’ activities, reduce our revenues, and increase our operating costs, including the cost to insure offshore operations, resulting in reduced cash flows and profitability.

We encounter, and expect to continue to encounter, intense competition in the sale of our products and services.

We compete with numerous companies in each of our operating segments, many of which have substantially greater financial and other resources than we have. To the extent competitors offer comparable products or services at lower prices or higher quality, more cost-effective products or services, our business could be materially and adversely affected. In addition, certain of our customers may elect to perform services internally in lieu of using our services. Such activity could materially and adversely affect our operations.

The profitability of our operations is dependent on other numerous factors beyond our control.

Our operating results in general, and gross profit in particular, are functions ofdetermined by market conditions and the productproducts and service mix soldservices we sell in any period. Other factors, such as heightened competition, changes in sales and distribution channels, availability of skilled labor and contract services, shortages in raw materials, or inability to obtain supplies at reasonable prices, may also affect the cost of sales and the fluctuation of gross margin in future periods.

Other factors affecting our operating results and activity levels include finding, development, and acquisition costs of oil and natural gas reserves; oil and gas industry spending levels for exploration, development, and acquisition activities; plugging, abandonment, and decommissioning costs on Maritech’s remaining offshore production costs; pluggingplatforms and abandonment costs; insurance costs; the success rates of new oil and gas reserve development; and the remaining recoverable reserves in the basins in which we operate.associated wells. A large concentration of our operating activities is located in the onshore and offshore U.S. Gulf Coast region. Our revenues and profitability are particularly dependent upon oil and natural gas industry activity and spending levels in this region. Our operations may also be affected by technological advances, cost of capital, and tax policies, and overall worldwide economic activity.policies. Adverse changes in any of these other factors may depress the levels of well drilling, completion, workover, and production activity and result in a corresponding decline in the demand for our products and services, thereby havinghave a material adverse effect on our revenues and profitability.
15

We encounter and expect to continue to encounter intense competition in the sale of our products and services.

We compete with numerous companies in our operations. Many of our competitors have substantially greater financial and other related resources than we have. To the extent competitors offer comparable products or services at lower prices, or higher quality, more cost-effective products or services, our business could be materially and adversely affected.

We are dependent on third-party suppliers for specific products and equipment necessary to provide certain of our products and services.

We sell a variety of clear brine fluids to the oil and gas industry, including calcium chloride, calcium bromide, zinc bromide, zinc calcium bromide, and sodium bromide, some of which we manufacture and some of which are purchased from third parties. We also sell calcium chloride and sodium bromide to non-energy markets. Sales of calcium chloride and bromide compound products contribute significantly to our revenues. In our manufacture of calcium chloride, we use brines, hydrochloric acid, and other raw materials purchased from third parties. In our manufacture of bromide compound products, we use bromine,underground brines, hydrobromic acid, and other raw materials including various forms of zinc, which are purchased from third parties. We rely on Chemtura as a supplier of raw materials, both for our bromide compound products as well as for our El Dorado, Arkansas, calcium chloride plant. We also acquire bromide compound products from several third-party suppliers. If we are unable to acquire the bromide compound products, bromine, hydrobromic or hydrochloric acid, zinc, or any other supplies ofthese raw materialmaterials at reasonable prices for a prolonged period, our business could be materially and adversely affected.

As a result of the continuing general economic conditions, many chemical manufacturers are experiencing reduced demand, production interruptions, and financial difficulties. For example, during March 2009, Chemtura announced that it and its affiliates had filed voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy code. Under bankruptcy, Chemtura had the right to accept or reject executory contracts, including certain of our agreements with them under which we acquire raw material bromine and brine. During the fourth quarter of 2009, we negotiated certain amendments to our existing agreements with Chemtura, and such amended agreements were signed by Chemtura and approved by the bankruptcy court. Also during 2009, we wrote down the value of our investment in a European calcium chloride manufacturing joint venture following our joint venture partner’s announced shutdown of its adjacent plant facility that supplies feedstock to the joint venture’s plant. In addition, occasional raw material supply constraints have resulted in certain of our manufacturing facilities operating at less than full capacity, resulting in decreased production volumes. Most recently, the diminished availability of economical raw materials has led to the shutdown of our Lake Charles, Louisiana, calcium chloride plant facility’s dry product manufacturing operation. The availability of feedstock raw materials at economical prices may continue to affect the operations of our various manufacturing facilities going forward. The purchase of alternative raw material supplies at a less favorable cost could also result in decreased profitability.

Some of the well plugging, abandonment and decommissioning services performed by our Offshore Services segment require the use of vessels, diving, cutting, and other equipment, and services provided by third parties. We lease equipment and obtain services from certain providers;providers and there can be no assurance that this equipment and these services are subject to availabilitywill be available at reasonable prices of which there can be no assurance.in the future.

The fabrication of our production testing equipment and wellhead compressor units requires the purchase of many types of components, some of which we obtain from a single source or a limited group of suppliers. Our reliance on these suppliers exposes us to the risk of price increases, inferior component quality, or an inability to obtain an adequate supply of required components in a timely manner. The profitability or future growth of our Production Enhancement Division may be adversely affected due to our dependence on these key suppliers.

Our exploration and production operations are subject to the availability of drilling rigs, tubular products, and numerous other products and services at reasonable prices.

We may not be ableThe majority of our business in Mexico is performed for Petróleos Mexicanos (PEMEX) and, due to obtain access to pipelines, gas gathering, transmission,our dependence on PEMEX as a significant customer, any cutbacks by the Mexican Government on PEMEX’s annual spending budget or security disruptions in Mexico could adversely affect our business, financial condition, results of operations and processing facilities to market our oil and gas production.cash flows.

The marketingmajority of oilour business in Mexico is performed for PEMEX. For the twelve months ended December 31, 2011, PEMEX accounted for approximately 4.8% of our consolidated revenues. No work or services are guaranteed to be ordered by PEMEX under our contracts with PEMEX. PEMEX is a decentralized public entity of the Mexican Government, and gas production depends in large part ontherefore the availability, proximity, and capacity of pipelines, gas gathering systems, and other transportation, processing and refining facilities,Mexican Government controls PEMEX, as well as its annual budget, which is approved by the existence of adequate markets. If there was insufficient capacity available on these systems,Mexican Congress. The Mexican Government may cut spending in the future. These cuts could adversely affect PEMEX’s annual budget and, thus, its ability to engage us or if these systems were unavailable tocompensate us the price offered for our productionservices and, as a result, our business, financial condition, results of operations and cash flows.

During the past two years, incidents of security disruptions throughout many regions of Mexico have increased. Drug related gang activity has grown in response to Mexico’s efforts to reduce and control drug trafficking within the country. Certain incidents of violence have occurred in regions served by us and have resulted in the interruption of our operations and these interruptions could continue or increase in the future. To the extent that such security disruptions continue or increase, our operations will continue to be affected, and the levels of revenue and operating cash flow from our Mexican operations could be significantly depressed, or we could be forced to shut-in some production or delay or discontinue drilling plans while we construct our own facilities. We also rely on facilities developed and owned by third parties in order to process, transmit, and sell our oil and gas production. Currently, a portion of Maritech’s Main Pass field is shut-in due to third-party pipeline issues and the lack of available transportation for production. This produ ction may remain shut-in indefinitely while we await a resolution by third parties and consider alternative transportation options. Our plans to develop and sell our oil and gas reserves could be materially and adversely affected by the inability or unwillingness of third parties to provide sufficient transmission or processing facilities to us.reduced.

TheChanges in the economic environment could result in significant impairments of certain of our long-lived assets, including goodwill.

TheAlthough the overall global economy has largely recovered from the 2008 recession, significant economic uncertainty remains. Changes in the economic environment could result in decreased demand for many of our products and services, which could impact the expected utilization rates of certain of our long-lived assets, including plant facilities, operating locations, vessels, and other operating equipment. Under generally accepted accounting principles, we review the carrying value of our long-lived assets when events or changes in circumstances indicate that the carrying value of these assets may not be recoverable, based on their expected future cash flows. The impact of reduced expected future cash flow could require the write-down of all or a portion of the carrying value for these assets, which would result in an impairment charge to earnings, resulting in increased earnings volatility.

Under generally accepted accounting principles, we review the carrying value of our goodwill for possible impairment annually or when events or changes in circumstances indicate the carrying value may not be recoverable. Changes in circumstances indicating the carrying value of our goodwill may not be recoverable include a decline in our stock price and our market capitalization, future cash flows, and slower growth rates in our industry. If economic and market conditions decline, we may be required to record a charge to earnings during the period in which any impairment of our goodwill is determined, resulting in a negative impact on our results of operations.

Our success depends upon the continued contributions of our personnel, many of whom would be difficult to replace, and the continued ability to attract new employees.

Our success depends on our ability to attract, train, and retain skilled management and employees at reasonable compensation levels. The delivery of our products and services requires personnel with specialized skills and experience. In addition, our ability to expand our operations depends in part on our ability to increase the size of our skilled labor force. The demand for skilled managers and workers in the U.S. Gulf Coast region and other regions in which we operate is high, and the supply is limited. A lack of qualified personnel, therefore, could adversely affect operating results.

16

Operating, Technological, and Strategic Risks

Our operations involve significant operating risks, and insurance coverage may not be available or cost effectivecost-effective.

We are subject to operating hazards normally associated with the oilfield service industry, and offshore oil and gas production operations, including fires, explosions, blowouts, formation collapse, mechanical problems, abnormally pressured formations, and environmental accidents. Environmental accidents could include, but are not limited to: oil spills; gas leaks or ruptures; uncontrollable flows of oil, gas, or well fluids; or discharges of CBFs or toxic gases or other pollutants. These operating hazards may also include injuries to employees and third parties during the performance of our operations. Our operation of marine vessels, heavy equipment, offshore production platforms, and the performance of heavy lift and diving
17

services involve particularly high levels of risk. In addition, certain of our employees who perform services on offshore platforms and vessels are covered by the provisions of the Jones Act, the Death on the High Seas Act, and general maritime law. These laws make the liability limits established by state workers’ compensation laws inapplicable to these employees and, instead, permit them or their representatives to pursue actions against us for damages for job-related injuries. Whenever possible, we obtain agreements from customers and suppliers that limit our exposure. However, the occurrence of certain operating hazards, including storms, could result in substantial losses to us due to injury or loss of life, damage to or destruction of property and equipment, pollution or environmental damage, and suspension of operations.

We have maintained a policy of insuring our risks of operational hazards that we believe is typical in the industry. Limits of insurance coverage we have purchased are consistent with the exposures we face and the nature of our products and services. Due to economic conditions in the insurance industry, from time to time, we have increased our self-insured retentions for certain policies in order to minimize the increased costs of coverage. In certain areas of our business, we, from time to time, have elected to assume the risk of loss for specific assets. To the extent we suffer losses or claims that are not covered, or are only partially covered by insurance, our results of operations could be adversely affected.

We face risks related to our growth strategy.

Our growth strategy includes both internal growth and growth through acquisitions. Internal growth may require significant capital expenditures, some of which may become unrecoverable or fail to generate an acceptable level of cash flows. Internal growth may also require financial resources (including the use of available cash or additional long-term debt) and management and personnel resources. Acquisitions also require significant financial and management resources, both at the time of the transaction and during the process of integrating the newly acquired business into our operations. If we overextend our current financial resources by growing too aggressively, we could face liquidity problems or have difficulty obtaining additional financing. Any recent or future acquisition transactions by us may not achieve favorable financial results. Our operating results could be adversely affected if we are unable to successfully integrate newly acquired companies into our operations, are unable to hire adequate personnel, or are unable to retain existing personnel. We may not be able to consummate future acquisitions on favorable terms. Acquisition or internal growth assumptions developed to support our decisions could prove to be overly optimistic. Future acquisitions by us could result in issuances of equity securities, or the rights associated with the equity securities, which could potentially dilute earnings per share. Future acquisitions could result in the incurrence of additional debt or contingent liabilities and amortization expenses related to intangible assets. These factors could adversely affect our future operating results and financial position.

We have technological and age obsolescenceage-obsolescence risk, both with our products and services as well as with our equipment assets.

Competitors constantly evolve their technologies and methodologies and replace their used assets with new assets. If we are unable to adapt to new advances in technology or replace mature assets with new assets, we are at risk of losing customers and market share. In particular, many of our most significant equipment assets, including heavy lift barges and dive support vessels, are approaching the end of their useful lives, which may adversely affect our ability to serve certain customers. The permanent replacement or upgrade of any of our vessels will require significant capital. Due to the unique nature of many of these vessels, finding a suitable or acceptable replacement may be difficult and/or cost prohibitive. The replacement
17

or enhancement of these vessels over the next several years may be necessary in order for the Offshore Services segme ntsegment to effectively compete in the current marketplace.

The production volumes and profitability from our El Dorado, Arkansas, calcium chloride plant facility may not be as timely orhigh as high asoriginally expected.

During late 2009 and early 2010, we completed the construction and began the commissioning of a calcium chloride plant facility near El Dorado, Arkansas. During 2010, the El Dorado plant experienced significant start-up costs and early production inefficiencies that resulted in decreased profitability levels compared to our estimates. We continue to take steps to improve the operational efficiency of the plant, however, there is still a considerable effort required, and significant improvement in plant performance is not expected until mid-2011. We believe that significant additional capital investment may be necessary,
18

depending on the plant’s performance during the first half of 2011. The plant’s future profitability and the advantages we expect to receive from the plant will be based on many factors, including the level of production from the plant, our ability to improve the plant’s performance, sales prices to be received for the plant’s products, raw material and operating costs, our ability to improve the plant’s performance, and future demand for products. There can be no assurance that the El Dorado, Arkansas, plant’s future profitability will achieve original expectations.

We could incur losses on fixed price contracts.

Due to competitive market conditions, a portion of our well abandonment and decommissioning projects may be performed on a turnkey, modified turnkey,lump sum or day-ratequalified lump sum basis. Pursuant to these types of contracts, defined work is delivered for a fixed price, and extra work, which is subject to customer approval, is charged separately. The revenue, cost, and gross profit realized on these types of contracts can vary from the estimated amount because of changes in offshore conditions, increases in the scope of the work to be performed, increased site clearance efforts required, labor and equipment availability, cost and productivity levels, and the performance level of other contractors. In addition, unanticipated events, such as accidents, work delays, significant changes in the condition of platforms or wells, downhole problems, and environmental or othe rother technical issues, could result in significant losses on these types of projects. These variations and risks may result in our experiencing reduced profitability or losses on these types of projects or on well abandonment and decommissioning work for our Maritech subsidiary.

Oil and gas exploration and production activities involve numerous risks and are subject to a varietyThe valuation of factors that we cannot control.

We have risks associated with our Maritech exploration and production business. These risks include those associated with finding and developing economically recoverable and marketable oil and natural gas reserves, and finding and acquiring leases and existing reserves on attractive terms. There are inherent uncertainties surrounding estimates of oil and gas reserve volumes, finding and development costs, production costs, and abandonment and decommissioning costs. To the extent we overestimate future oil and natural gas sales prices, economically recoverable reserve volumes, or future production flow rates, or we underestimate the associated costs of exploration and production operations, our financial results will be negatively impacted.

Drilling for oil and natural gas is a particularly risky activity that includes the risk that we will not encounter commercially productive oil or natural gas reservoirs. The costs of drilling and completion operations are often difficult to estimate, and the timing of drilling operations may be curtailed, delayed, or canceled as a result of a variety of factors including, but not limited to:
·  unexpected drilling conditions;
·  pressure or irregularities in formations;
·  equipment failures or accidents;
·  marine risks such as capsizing and collisions;
·  hurricanes and other adverse weather conditions;
·  shortages or delays in the delivery of equipment; and
·  compliance with environmental and other government requirements.

During the three year period ended December 31, 2010, we have expended approximately $182.4 million of exploration and development costs, and we may incur significant costs in the future. During the three year period ended December 31, 2010, we charged approximately $9.3 million of dry hole costs incurred to earnings. Future drilling activities may not be successful, and, if unsuccessful, this could have an adverse effect on our future results of operations and financial condition. We may not recover all or any portion of our investment in new wells. We are often uncertain as to the future cost or timing of drilling, completing, and operating wells. While all drilling, whether developmental or exploratory, involves these risks, exploratory drilling involves greater risks of dry holes or failure to find commercial quantities of hydrocarbons.

Maritech’s estimates of its oil and gas reserves and related future cash flows are based on many factors and assumptions, including various assumptions that are based on changing conditions in existence as of the dates of the estimates. Any material changes in those conditions, or other factors affecting those assumptions, could impair the quantity and value of our oil and gas reserves.

Maritech’s estimates of oil and gas reserve information are prepared in accordance with Rule 4-10 of Regulation S-X and reflect only estimates of the accumulation of oil and gas and the economic recoverability of those volumes. Maritech’s future production, revenues, and expenditures with respect to such oil and gas reserves will likely be different from estimates, and any material differences may negatively affect our business, financial condition, and results of operations. As a result, Maritech has experienced, and may continue to experience, significant revisions to its reserve estimates.

Oil and gas reservoir analysis is a subjective process which involves estimating underground accumulations of oil and gas that cannot be measured in an exact manner. Estimates of economically recoverable oil and gas reserves and of future net cash flows associated with such reserves necessarily depend upon a number of variable factors and assumptions. Because all reserve estimates are to some degree subjective, each of the following items may prove to differ materially from that assumed in estimating reserves:
·  the quantities of oil and gas that are ultimately recovered;
·  production flow rates over time;
·  the production and operating costs incurred;
·  the amount and timing of future development and abandonment expenditures; and
·  future oil and gas sales prices.

Furthermore, different reserve engineers may make different estimates of reserves and cash flow based on the same available data.

The estimated discounted future net cash flows from proved reserves described in this Annual Report for the year ended December 31, 2010, should not be considered as the current market value of the estimated oil and gas proved reserves attributable to Maritech’s properties. Such estimates are based on prices and costs in accordance with SEC requirements, while future prices and costs may be materially higher or lower. Using lower prices in forecasting reserves will result in a shorter life being given to producing oil and natural gas properties, because such properties, as their production levels are estimated to decline, will reach an uneconomic limit with lower prices at an earlier date. There can be no assurance that a decrease in oil and gas prices or other differences in Maritech’s estimates of its reserves will not adversely affe ct our financial position or results of operations.

The acquisition of oil and gas properties and their associated well abandonment and decommissioning liabilities is based on estimated data that may be materially incorrect.

In conjunction with our acquisition of oil and gas properties, we perform detailed due diligence review processes that we believe are consistent with industry practices. These acquired properties consist of both mature properties, which are generally in the later stages of their economic lives, as well as exploration and prospect opportunities. Each acquisition of oil and gas properties requires a thorough review of the expected cash flows acquired and the associated abandonment obligations assumed. The process of estimating oil and natural gas reserves is complex, requiring significant decisions and assumptions to be made in evaluating the available geological, geophysical, engineering, and economic data for each reservoir. The volatility of oil and natural gas commodity pricing additionally complicates the calculation of estimated future cash fl ows of properties to be acquired. As a result, these estimates are inherently imprecise. Actual future production, cash flows, development expenditures, operating and abandonment expenses, and quantities of recoverable natural gas and oil reserves may vary substantially from those initially estimated by us. Also, in conjunction with the purchase of certain oil and gas properties, we assume our proportionate share of the related well abandonment and decommissioning liabilities after performing detailed estimating procedures, analysis, and engineering studies. Our estimates of these future well abandonment and decommissioning liabilities are imprecise and are subject to change due to changes in the forecasts of the supply, demand, pricingcost and timing of well abandonment and decommissioning services; damage to wells and infrastructure caused by hurricanes and other natural events; changes in governmental regulations governing well abandonment and
20

decommissioning work; and other factors. In particular, a portion of the remaining decommissioning liabilities for our Maritech subsidiary relate to offshore production platforms that were toppled and destroyed during 2005 and 2008 hurricanes, and the estimates to perform the work on these properties is particularly imprecise due to the unusual nature of the work to be performed. During 2010,2011, Maritech adjusted its decommissioning liabilities, increasing them by approximately $130.8$80.2 million, either for work performed during the year or related to adjusted estimates of the cost of future work to be performed. Approximately $54.0$78.4 million of this adjustment was directly charged to earnings as an operating expense and the remainder was charged to the associated properties and partly contributed to asset impairments during 2010.2011. If the actual cost of future abandonment and decommissioning work is materially greater than our current estimates, such additional costs could have an additional adverse effect on earnings.

Acquisitions or discoveries of additional reserves are needed to avoid a material decline in oil and gas reserves and production volumes.

The rate of production from oil and gas properties generally declines as reserves are depleted. Approximately 42.7% of our proved reserves as of December 31, 2010, are proved producing reserves. Except to the extent that we find or acquire additional properties containing estimated proved reserves; conduct successful exploration or development activities; or through engineering studies, identify additional behind-pipe zones, secondary recovery reserves, or tertiary recovery reserves, our estimated proved reserves will decline materially as reserves are produced. Natural gas and oil commodity pricing, as well as constraints on the amount of capital we have available to allocate to oil and gas activities, may limit our exploitation, development, or exploration activities for the foreseeable future, which will reduce our ability to replace produced o il and gas reserves. Future oil and gas production is, therefore, highly dependent upon our ability and level of success in acquiring or finding additional reserves.

Our accounting for oil and gas operations may result in volatile earnings.

We account for our oil and gas operations using the successful efforts method. Costs incurred to drill and equip development wells, including unsuccessful development wells, are capitalized. Costs related to unsuccessful exploratory wells are expensed as incurred. All capitalized costs are accumulated and recorded separately for each field and are depleted on a unit-of-production basis, based on the estimated remaining equivalent proved oil and gas reserves of each field. The capitalized costs of our oil and natural gas properties, on a field basis, cannot exceed the estimated undiscounted future net cash flows of that field. If net capitalized costs exceed undiscounted future net revenues, we must write down the costs of each such field to our estimate of its fair market value. Accordingly, a significant decline in oil or natural gas prices, unsu ccessful exploration and/or development efforts, or an increase in our decommissioning liabilities could cause a future write-down of capitalized costs. During the three year period ended December 31, 2010, and primarily due to increased decommissioning liabilities and the decrease in oil and natural gas prices, we recorded oil and gas property impairments totaling approximately $117.8 million. Unproved properties are evaluated at the lower of cost or fair market value. On a field by field basis, our oil and gas properties are assessed for impairment in value whenever indicators become evident, with any impairment charged to expense. Under the successful efforts method of accounting, we are exposed to the risk that the value of a particular property (field) would have to be written down or written off if an impairment were present.

Weather RelatedWeather-Related Risks

Certain of our operations, particularly those conducted offshore, are seasonal and depend, in part, on weather conditions.

The Offshore Services segment has historically enjoyed its highest vessel utilization rates during the period from April to October, when weather conditions are typically more favorable for offshore activities, and has experienced its lowest utilization rates in the period from November to March. This segment, under certain turnkeylump sum and other contracts, may bear the risk of delays caused by adverse weather conditions. Severe storms can also cause our oil and gas producing properties to be shut-in. In addition, demand for other products and services we provide are subject to seasonal fluctuations, due in part to weather conditions that cannot be predicted. Accordingly, our operating results may vary from quarter to quarter, depending on weather conditions in applicable areas.

Severe weather, including named windstorms, can cause significant damage and disruption to our businesses.

A significant portion of our operations is susceptible to adverse weather conditions in the Gulf of Mexico, including hurricanes and other extreme weather conditions. High winds, rising water, storm surge, and turbulent seas can cause significant damage and curtail our operations for extended periods during and after such weather conditions, while damage is being assessed and remediated. The costs to bring damaged offshore wells under control and to repair or remove damaged offshore platforms, pipelines, vessels, or other equipment can be significant. Moreover, evenEven if we do not experience direct damage from storms, we may experience disruptions in our operations because we are unable to operate or our customers or suppliers may curtail their activities due to damage to their wells, platforms, pipelines, and other facilities.

We incurred a significant amountA portion of damagethe costs to repair damages as a result of 2005 and 2008 hurricanes and a portion of these costs havehas yet to be incurred and may not be covered under our insurance policies.result in significant charges to earnings.

We incurred significant damage to certainDuring the past three years, Maritech has performed an extensive amount of our onshorewell intervention, abandonment, decommissioning, debris removal, and platform construction associated with six offshore operating equipmentplatforms that were destroyed by Hurricanes Rita and facilitiesIke during the third quarters of 2005 and 2008, primarily as a resultrespectively. As of Hurricanes Katrina, Rita, and Ike. In particular, our Maritech subsidiary suffered varying levels of damage to the majority of its offshore oil and gas producing platforms, and six of its platforms were destroyed by these storms. In addition, two production facilities located in inland waters were destroyed.December 31, 2011, Maritech has reconstructed theremaining work associated with two destroyed production facilities, and four of the destroyed platforms have been decommissioned. A majority of our damaged assets, withdowned platforms. The estimated cost to perform the exception of the remaining destroyed Maritech platforms, have been repaired or are in the final stages of being repaired, and have resumed operation. Remaining hurricane damage repair efforts consist pr imarily of the well intervention, abandonment, decommissioning, and debris removal associated with the remaining destroyed offshore platforms and the redrilling of a number of destroyed wells to be redrilled from a newly constructed replacement platform. While a large portion of the well intervention, abandonment, and decommissioning work has been performed on some of the destroyed platforms and the inland water production facilities, a significant amount of the work has yet to be performed. Through December 31, 2010, we have expendedis approximately $125.0 million for the well intervention, abandonment, decommissioning, platform reconstruction, and debris removal work performed on the platforms and production facilities which were destroyed by the storms. The remaining well intervention and subsequent debris removal efforts are expected to be performed during 2011. We estimate that the remaining abandonment, decommissioning, debris removal, and well redrilling efforts associated with the destroyed platforms w ill be performed at an additional cost of approximately $50 to $65$27.5 million net to our interest and before any insurance recoveries. ActualDue to the unique nature of the remaining work to be performed, actual costs could greatly exceed these estimates and, depending on the nature of any excess costs incurred, could result in significant charges to earnings in future periods.

Following the collection All of $47.8this $27.5 million insurance settlement proceeds during 2010 associated with Hurricane Ike,estimated amount has been accrued as part of Maritech’s decommissioning liabilities. Maritech has additional maximum remaining insurance coverage available of approximately $19.5 million, all of which relates to Hurricane Ike. With regard to the damages associated with Hurricane Ike, we have performed a significant majority of the property repairs on the damaged and destroyed platforms. These efforts included the reconstruction of the destroyed East Cameron 328 platform and the initial redrilling efforts of wells associated with this destroyed platform. Despite our confidence that the majority of the remaining repair, debris removal, and well redrilling costs relating to Hurricane Ike will qualify as covered costs pursuant to our insurance coverage,although a portion of these coststhis coverage may not be reimbursed.utilized. One of the underwrite rsunderwriters associated with our windstorm insurance coverage for Hurricane Ike damages has contested whether certain repair costs incurred are covered costs under the policy. During December 2010, we initiated legal proceedings against this underwriter in an attempt to collect the amount of claim reimbursements provided for under the policy. The timing of the collection of any future reimbursements is beyond our control, and we will continue to use a significant amount of our working capital until such reimbursements are received. In addition, a portion of the reimbursements ultimately received may be offset by legal and other administrative costs incurred in our attempts to collect them. Our estimates of the remaining costs to be incurred may be imprecise. To the extent actual future costs exceed the policy maximum for these costs, such excess costs would not be reimbursable.

Our oilWe have elected to self-insure windstorm damage to our remaining Maritech assets in the Gulf  of Mexico, and gas production levels continue to be affected by the 2008 hurricanes.hurricane damages could result in significant uninsured losses.

Our operating cash flows continue to be affected byDespite the interruption insale of approximately 95% of Maritech’s oil and gas production as a resultreserves during 2011, we have retained decommissioning liabilities of damage toapproximately $132.8 million associated with offshore platforms and pipelines caused by the 2008 hurricanes. One of the destroyed offshore platforms was on the East Cameron 328 field, which is a key producing field. During the fourth quarter of 2009, Maritech modified one of the remaining platforms in this field and has restored a portion of the interrupted production. During 2010, Maritech completed the construction of a new offshore production platform to replace the destroyed platform, and has begun redrilling certainassociated wells from the new platform. These redrill efforts are estimated to cost approximately $13 to $19 million, before insurance recoveries, and are scheduled to be completed in 2011. With regard to the shut-in production, our insurance protecti on does not include business interruption coverage. While repairdecommissioned and recovery efforts have been prioritized to restore Maritech’s production as soon as possible, these production restoration efforts are expected to continue into 2011 and beyond. The full resumption of Maritech’s pre-storm production levels may never occur.

Windstorm insurance coverage for Gulf of Mexico offshore oil and gas production operations is costly, and may result in significant uninsured losses for our Maritech operations.

In the past, we have maintained windstorm insurance that is designed to cover damages to our Maritech platforms, equipment, and other assets located in the Gulf of Mexico. As a result of hurricanes in 2005 and 2008, Maritech suffered varying levels of damage to a majority of its offshore platforms, and several platforms were destroyed. Following these storms, insurance premiums and deductibles for windstorm insurance covering these assets increased dramatically, and policy limits and sub-limits were decreased dramatically.abandoned. During the second quarter of 2009,2011, we determined that the cost of premiums and the associated deductibles and coverage limits for windstorm damage for Maritech’s remaining offshore properties made the continuation of such coverage uneconomical,platforms and wells was uneconomical. Therefore, Maritech discontinued its insurance coverage for windstorm damage through May 2010, e lectingdamage. Accordingly, Maritech is currently exposed to self-insure for these damages. Duringlosses from windstorm damages and may be similarly exposed to storms in the second quarter of 2010,future if we purchaseddo not purchase windstorm insurance coverage for the June 2010 through May 2011 season, but with significantly decreased policy limits and sub-limits and increased deductibles. If premiums, deductibles, and policy limits for windstorm insurance remain as unfavorable for the June 2011 through May 2012 season, we may once again choose to retain a significant amount of hurricane risk.coverage. Depending on the severity and location of anythe storms, during a period in which we are self-insured or carry high deductibles, uninsuredsuch losses could be significant and could have a material adverse effect on our financial position, results of operations,operation, and cash flows.

There can be no assurance that future insurance coverage with more favorable deductiblepremiums and deductibles and maximum coverage amounts will be available in the market or that its cost will be justifiable. There can be no assurance that any windstorm insurance will be adequate to cover losses or liabilities associated with operational hazards.such windstorms. We cannot predict the continued availability of insurance or its availability at premium levels that justify its purchase.

Financial Risks

Significant deterioration of our financial ratios could result in covenant defaults under our long-term debt agreements and result in decreased credit availability.

As of December 31, 2010,2011, our total debt outstanding was approximately $305.0 million, and our debt to total capital ratio was 37.1%45.5%. This debt to total capital ratio excludes approximately $65.4$204.4 million of available cash held as of December 31, 2010.2011. Additional growth could result in increased debt levels to support our capital expenditure needs or acquisition activities. Debt service costs related to outstanding long-term debt represent a significant use of our operating cash flow and could increase our vulnerability to general adverse economic and industry conditions. Our long-term debt agreements contain customary covenants and other restrictions and requirements. In addition, the agreements require us to maintain certain financial ratio requirements. Significant deterioration of these ratios could result in a default under the agreements. The a greementsagreements also include cross-default provisions relating to any other indebtedness we have that is greater than a defined amount. If any such indebtedness is not paid or is accelerated and such event is not remedied in a timely manner, a default will occur under the long-term debt agreements. Any event of default, if not
23

timely remedied, could result in a termination of all commitments of the lenders and an acceleration of any outstanding loans and credit obligations.

We are exposed to significant credit risks.

We face credit risk associated with the significant amounts of accounts receivable we have with our customers in the energy industry. Many of our customers, particularly those associated with our onshore operations, are small-sized to medium-sized oil and gas operating companies that may be more susceptible to fluctuating oil and gas commodity prices or generally increased operating expenses than larger companies. Our ability to collect from our customers may be impacted by adverse changes in the energy industry.

Maritech purchases interests in oil and gas properties in connection with the operations of our Offshore Division. As the owner and operator of thesecertain oil and gas property interests, Maritech is liable for the proper abandonment and decommissioning of the wells, platforms, and pipelines, as well as the site clearance related to these properties. We have guaranteed a portion of the abandonment and decommissioning liabilities of Maritech. In certain instances, Maritech is entitled to be paid in the future for all or a portion of these obligations by the previous owner of the property once the liability is satisfied. We and Maritech are subject to the risk that the previous owner(s) will be unable to make these future payments. In addition, iffor certain remaining Maritech acquires less than 100%properties to be decommissioned or abandoned, the co-owners of the working interest in a property, its co-ownerssuch properties are responsible for the payment of their por tionsportions of the associated operating expenses and abandonment liabilities. However, if one or more co-owners do not pay their portions, Maritech and any other nondefaulting co-owners may be liable for the defaulted amount. If any required payment is not made by a previous owner or a co-owner and any security is not sufficient to cover the required payment, we could suffer material losses.

We may have continuing exposure on abandonment and decommissioning obligations associated with oil and gas properties sold by Maritech.

During 2011, in connection with the sale of a significant majority of Maritech’s oil and gas producing properties, the buyers of the properties assumed associated decommissioning liabilities of approximately $122.0 million pursuant to the purchase and sale agreements. For oil and gas properties for which Maritech was previously the operator, the buyer of the properties has now generally become the successor operator, and has assumed the financial responsibilities associated with the properties’ operations. However, to the extent that purchasers of these oil and gas properties fail to perform the abandonment and decommissioning work required, and there is insufficient bonding and we have insufficient other security, the previous owners and operators of the properties, including Maritech, may be required to assume responsibility for the abandonment and decommissioning obligation. To the extent Maritech is required to assume or perform a significant portion of the abandonment and decommissioning obligations associated with these sold oil and gas properties, our financial condition and results of operations may be negatively affected.
20

Our operating results and cash flows for certain of our subsidiaries are subject to foreign currency risk.

The operations of certain of our subsidiaries are exposed to fluctuations between the U.S. dollar and certain foreign currencies. Our plans to grow our international operations could cause this exposure from fluctuating currencies to increase. In particular, our growing operations in Brazil, as a result of a long-term contract with Petrobras entered into during 2008, subjects us to increased foreign currency risk in that country. Historically, exchange rates of foreign currencies have fluctuated significantly compared to the U.S. dollar, and this exchange rate volatility is expected to continue. Significant fluctuations in foreign currencies against the U.S. dollar could adversely affect our balance sheet and results of operations.

Compressco Partners may not generate sufficient cash from operations to make cash distributions to its common and subordinated unitholders.

Compressco Partners may not generate sufficient cash from operations to enable it to make cash distributions to holders of common units at the minimum quarterly distribution rate under its cash distribution policy. To the extent Compressco Partners has insufficient available cash to distribute, the distribution shortfall will first be attributed to the subordinated units we hold, resulting in a reduction in our financing cash flows from distributions from Compressco Partners. Any shortfall in quarterly distributions attributed to the subordinated units will not be carried forward in arrears or recovered in future distributions.

We are exposed to interest rate risk with regard to our indebtedness.

Our revolving credit facility consists of floating rate loans that bear interest at an agreed upon percentage rate spread above LIBOR. Although as of December 31, 2010,2011, there is no balance outstanding under the revolving credit facility, there is no assurance that we will not borrow under the facility in the future. Accordingly, our cash flows and results of operations could be subject to interest rate risk exposure associated with the level of the variable rate debt balance outstanding. We currently are not a party to an interest rate swap contract or other derivative instrument designed to hedge our exposure to interest rate fluctuation risk.

The terms governing our revolving credit facility were agreed to in October 2010, and it is scheduled to mature in 2015. The terms governing our Senior Notes were agreed to in April 2006, April 2008, and October 2010. These Senior Notes all bear interest at fixed interest rates and are scheduled to mature at various dates between April 2013 and December 2020. There can be no assurance that the financial market conditions or borrowing terms at the times these existing debt agreements are renegotiated will be as favorable.

Legal, Regulatory, and Political Risks

Our operations are subject to extensive and evolving U.S. and foreign federal, state and local laws and regulatory requirements that increase our operating costs and expose us to potential fines, penalties, and litigation.

Laws and regulations strictly govern our operations relating to: corporate governance, employees, taxation, fees, filing requirements, permitting requirements, environmental affairs, health and safety, waste management, and the manufacture, storage, handling, transportation, use, and sale of chemical products. Certain international jurisdictions impose additional restrictions on our activities, such as currency restrictions, importation and exportation restrictions, and restrictions on labor practices. Our operation and decommissioning of offshore properties are also subject to and affected by various government regulations, including numerous federal and state environmental protection laws and regulations. These laws and regulations are becoming increasingly complex and stringent, and compliance is becoming increasingly expensive. Governmental au thoritiesauthorities have the power to enforce compliance with these regulations, and violators are subject to civil and criminal penalties, including civil fines, injunctions, or both. Third parties may also have the right to pursue legal actions to enforce compliance. It is possible that increasingly strict environmental laws, regulations, and enforcement policies could result in substantial costs and liabilities to us and could subject our handling, manufacture, use, reuse, or disposal of substances or pollutants to increased scrutiny.
21

The EPA is performing a study of the environmental impact of hydraulic fracturing, a process used by the U.S. oil and gas industry in the development of oil and gas reservoirs. Specifically, the EPA is reviewing the impact of hydraulic fracturing wastewater and stormwater on drinking water resources through the use of scenario evaluation, laboratory and case studies, and an analysis of existing data. Certain environmental and other groups have suggested that additional federal, state and local laws and regulations may be needed to more closely regulate the hydraulic fracturing process. Several states have adopted regulations that require operators to disclose the chemical constituents in hydraulic fracturing fluids. In addition, the EPA has announced that it will release initial study results during 2012 and an additional report during 2014. We cannot predict whether any federal, state or local laws or regulations will be enacted regarding hydraulic fracturing, and, if so, what actions any such laws or regulations would require or prohibit. If additional levels of regulation or permitting requirements were imposed on oil and gas operators through the adoption of new laws and regulations, the demand for certain of our products and services could be decreased or subject to delays, particularly for our Production Testing and Fluids segments.

A large portion of Maritech’s oilremaining well abandonment and gasdecommissioning operations are conducted on offshore federal leases and are governed by increasing U.S. government regulations. During 2010, following the April 2010 Macondo well blowout and resulting oil spill in the Gulf of Mexico, the U.S. Minerals Management Service (MMS) was reorganized as the BOEMRE. The U.S. federal government imposed a drilling moratorium in the deepwater Gulf of Mexico that extended until October 2010. The BOEMRE has also issued formal Notice to Lessees (NTLs) and other safety regulations implementing additional safety and certification requirements applicable to drilling activities in the Gulf of Mexico that have resulted in operations and projects being curtailed or suspended. Government regulations also establish construction requirements for production facilities located on federal offs horeoffshore leases and govern the plugging and abandonment of wells and the removal of production facilities from these leases. Operators must now abide by new “Idle Iron Guidance” regulations that require that permanent plugs be set in nearly 3,500 nonproducing wells and that 650 oil and gas production platforms be dismantled if they are no longer being used. In October 2011, the BOEMRE’s responsibilities were divided between the BOEM and the BSEE, which will oversee the provisions of the “Idle Iron Guidance”. Under limited circumstances, the BOEMREBSEE could require us to suspend or terminate our operations on a federal lease. The BOEMREBOEM also establishes the basis for royalty payments due under federal oil and natural gas leases through regulations issued under applicable statutory authority.

We have significant operations that are either ongoing or scheduled to commence in the U.S. Gulf of Mexico. At this time, we cannot predict the full impact that other regulatory actions that may be mandated by the BOEMREFederal government may have on our operations or the operations of our customers. Other governmental or regulatory actions could further reduce our revenues and increase our operating costs, including the cost to insure offshore operations, resulting in reduced cash flows and profitability.

Our business exposes us to risks such as the potential for harmful substances escaping into the environment and causing damages or injuries, which could be substantial. Although we maintain general liability and pollution liability insurance, these policies are subject to exceptions and coverage limits. We maintain limited environmental liability insurance covering named locations and environmental risks associated with contract services for oil and gas operations and for oil and gas producing properties. We could be materially and adversely affected by an enforcement proceeding or a claim that is not covered or is only partially covered by insurance.

Federal legislation to reduce emissions of greenhouse gases (GHG) has been considered and many states have taken legal measures to reduce GHG emissions. It is not possible at this time to predict whether or when the U.S. Congress will pass climate change legislation, or how any bill approved by Congress may be reconciled with state and regional requirements. EPA has begun to promulgate federal rules under the Clean Air Act including mandatory reporting rules. On September 22, 2009, EPA issued a final rule requiring mandatory reporting of GHG from specified large GHG emission sources in the U.S. beginning in 2011 for emissions occurring in 2010. On November 30, 2010, EPA published a final rule expanding its existing GHG
25

emissions rule to include onshore and offshore oil and natural gas systems such as those operated by our Maritech subsidiary.

Because our business depends on the level of activity in the oil and natural gas industry, existing or future laws, regulations, treaties, or international agreements related tothat impose additional restrictions on the industry affect our business. Regulators are becoming more focused on air emissions from oil and gas operations including volatile organic compounds, hazardous air pollutants, and greenhouse gases. In particular, the focus on greenhouse gases and climate change, including incentives to conserve energy or use alternative energy sources, could have a negative impact on our business if such laws, regulations, treaties, or international agreements reduce the worldwide demand for oil and natural gas or otherwise result in reduced economic activity generally. In addition, such laws, regulations, treaties, or international agreements could result in increased compliance costs, capital spending requirements, or additional operating restrictions, which may have a negative impact on our business. In addition to potential impacts on
22

our business directly or indirectly resulting from climate-change legislat ionclimate change legislation or regulations, our business also could be negatively affected by climate-change relatedclimate change-related physical changes or changes in weather patterns.

In addition to increasing our risk of environmental liability, the rigorous enforcement of environmental laws and regulations has accelerated the growth of some of the markets we serve. Decreased regulation and enforcement in the future could materially and adversely affect the demand for the types of services offered by certain of our Offshore Services operations and, therefore, materially and adversely affect our business.

Climate change legislation or regulations restricting emissions of “greenhouse gases” could result in increased operating costs and reduced demand for the oil and natural gas our customers produce while the physical effects of climate change could disrupt production and cause us to incur costs in preparing for or responding to those effects.

On December 15, 2009, the EPA published its final findings that emissions of carbon dioxide, methane and other greenhouse gases (GHGs) present an endangerment to public health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the earth’s atmosphere and other climatic changes. These findings allow the EPA to adopt and implement regulations that would restrict emissions of GHGs under existing provisions of the federal Clean Air Act (CAA). Based on these findings, the EPA has begun adopting and implementing regulations to restrict emissions of GHGs under existing provisions of the CAA. The EPA recently adopted two sets of rules that became effective January 2, 2011 that regulate GHG emissions under the CAA, one of which requires a reduction in emissions of GHGs from motor vehicles and the other of which regulates emissions of GHGs from certain large stationary sources. The EPA has also adopted rules requiring the reporting, on an annual basis, beginning in 2011, of GHG emissions from specified large GHG emission sources in the United States, including petroleum refineries, for emissions occurring after January 1, 2010, as well as certain oil and gas production facilities, on an annual basis, beginning in 2012 for emissions occurring in 2011.

The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of GHGs from, our facilities and operations could require us to incur costs to reduce emissions of GHGs associated with our operations. Further, Congress has considered and almost one-half of the states have adopted legislation that seeks to control or reduce emissions of GHGs from a wide range of sources. Any such legislation could adversely affect demand for the oil and natural gas our customers produce and, in turn, demand for our products and services. Finally, it should be noted that some scientists have concluded that increasing concentrations of GHGs in the Earth’s atmosphere may produce climate changes that have significant physical effects, such as increased frequency and severity of storms, floods and other climatic events; if any such effects were to occur, they could have an adverse effect on our operations and cause us to incur costs in preparing for or responding to those effects.

Our proprietary rights may be violated or compromised, which could damage our operations.

We own numerous patents, patent applications, and unpatented trade secret technologies in the U.S. and certain foreign countries. There can be no assurance that the steps we have taken to protect our proprietary rights will be adequate to deter misappropriation of these rights. In addition, independent third parties may develop competitive or superior technologies.

Our expansion into foreign countries exposes us to complex regulations and may present us with new obstacles to growth.

We plan to grow both in the United States and in foreign countries. We have established operations in, among other countries, Brazil, Mexico, Argentina, Canada, the United Kingdom, Norway, Finland, Sweden, Ghana, and India, and have operating joint ventures in Saudi Arabia and Libya. A portion of our planned future growth includes expansion into additional countries. Foreign operations carry special risks. Our business in the countries in which we currently operate and those in which we may operate in the future could be limited or disrupted by:
 
·  government controls and government actions, such as expropriation of assets and changes in legal and regulatory environments;
 
·  import and export license requirements;
 
·  political, social, or economic instability;
23

 
·  trade restrictions;
 
·  changes in tariffs and taxes;
 
·  restrictions on repatriating foreign profits back to the United States;
 
·  the impact of anti-corruption laws and the risk that actions taken by us or others on our behalf may adversely affect our operations and competitive position in the affected countries; and
 
·  the limited knowledge of these markets or the inability to protect our interests.

We and our affiliates operate in countries where governmental corruption has been known to exist. While we and our subsidiaries are committed to conducting business in a legal and ethical manner, there is a risk of violating either the U.S. Foreign Corrupt Practices Act (FCPA) or laws or legislation promulgated pursuant to the 1997 OECD Convention on Combating Bribery of Foreign Public Officials in International Business Transactions or other applicable anti-corruption regulations that generally prohibit the making of improper payments to foreign officials for the purpose of obtaining or keeping business. Violation of these laws could result in monetary penalties against us or our subsidiaries and could damage our reputation and, therefore, our ability to do business.
26


Foreign governments and agencies often establish permit and regulatory standards different from those in the U.S. If we cannot obtain foreign regulatory approvals, or if we cannot obtain them when we expect, our growth and profitability from international operations could be negatively affected.

Maritech’s oil and gas operations are a separate segment included within our Offshore Division.

See also “Note R – Supplemental Oil and Gas Disclosures” in the Notes to Consolidated Financial Statements for additional information.

Oil and Gas Reserves

Through ourFollowing the 2011 sale of approximately 95% of Maritech’s proved oil and gas reserves as of December 31, 2010, Maritech subsidiary, we employ full-time, experienced reservoir engineershas retained selected staff and geologists,contractors who are responsible for determining proved oil and gas reserves in conformance with guidelines established by the SEC. These SEC guidelines were revised effective with the December 31, 2009, information. Reserve estimates were prepared by Maritech engineers, based upon theirthe interpretation of production performance data and geologic interpretation of sub-surface information derived from the drilling of wells. In accordance with Maritech’s documented oil and gas reserve policy as prescribed by our Board of Directors, the preparation of these reserve estimates is subject
25

to Maritech’s system of internal control, whereby key inputs in preparing reserve estimates, such as oil and natural gas pricing data, oil and gas property ownership int erestinterest percentages, and data regarding levels of operating, development, and abandonment costs, are reviewed by Maritech personnel outside of the reserve engineering department. Reserve estimates are also reviewed by Maritech’s President, who is also a licensed professional engineer and has overall responsibility for overseeing the preparation of the proved reserve estimates. In addition to the complete analysis and review by Maritech’s internal reservoir engineers, independent petroleum engineers and geologists performed reserve audits of approximately 92.2% of our proved reserve volumes as of December 31, 2010. The use of the term “reserve audit” is intended only to refer to the collective application of the engineering and geologic procedures that the independent petroleum engineering firms were engaged to perform and may be defined and used differently by other companies.

A reserve audit is the process of reviewing certain of the pertinent facts interpreted and assumptions made that have resulted in an estimate of reserves prepared by others and the rendering of an opinion about the appropriateness of the methodologies employed, the adequacy and quality of the data relied upon, the depth and thoroughness of the reserves estimation process, the classification of reserves appropriate to the relevant definitions used, and the reasonableness of the estimated reserve quantities. In performing a reserve audit, an independent petroleum engineering firm meets with our technical staff to collect all necessary geologic, geophysical, engineering, and economic data, and performs an independent reserve evaluation. The reserve audit of our oil and gas reserves involves the rigorous examination of our technical evaluation, as wel l as the interpretation and extrapolation of well information such as flow rates, reservoir pressure declines, and other technical information and measurements. Maritech’s internal reservoir engineers interpret this data to determine the nature of the reservoir and, ultimately, the quantity of proved oil and gas reserves attributable to the specific property. Our proved reserves, as reflected in this Annual Report, include only quantities that Maritech expects to recover commercially using current technology, prices, and costs, within
28

existing economic conditions, operating methods, and governmental regulation. While Maritech can be reasonably certain that the proved reserves are economically producible, the timing and ultimate recovery can be affected by a number of factors, including completion of development projects, reservoir performance, regulatory approvals, and changes in projections of long-term oil and gas prices. Revisions can include upward or downward changes in the previously estimated volumes of proved reserves for existing fields due to evaluation of (1) already available geologic, reservoir, or production data or (2) new geologic or reservoir data obtained from wells. Revisions can also occur associated with significant changes in development strategy, oil and gas prices or the related production equipment/facility capacity. Maritech’s independent pe troleum engineers also examined the reserve estimates with respect to reserve categorization, using the definitions for proved reserves set forth in Regulation S-X Rule 4-10(a), Staff Accounting Bulletin No. 113, and subsequent SEC staff interpretations and guidance.

Maritech engaged Ryder Scott Company, L.P. and DeGolyer and MacNaughton to perform the reserve audits of a portion of our oil and gas reserves as of December 31, 2010, 2009, and 2008. Both Ryder Scott Company, L.P. and DeGolyer and MacNaughton are established oil and gas reservoir engineering firms providing engineering services worldwide. The staffs of both of these firms, including the personnel assigned to the reserve audits of Maritech’s reserve estimates, include licensed reservoir engineers experienced in performing these services. In the conduct of these reserve audits, these independent petroleum engineering firms did not independently verify the accuracy and completeness of information and data furnished by Maritech with respect to property interests owned, oi l and gas production and well tests from examined wells, or historical costs of operation and development; however, they did verify product prices, geological structural and isopach maps, along with reservoir data such as well logs, core analyses, and pressure measurements. If, in the course of the examinations, a matter of question arose regarding the validity or sufficiency of any such information or data, the independent petroleum engineering firms did not accept such information or data until all questions relating thereto were satisfactorily resolved. Furthermore, in instances where decline curve analysis was not adequate in determining proved producing reserves, the independent petroleum engineering firms performed volumetric analysis, which included the analysis of geologic, reservoir, and fluids data. Proved undeveloped reserves were analyzed by volumetric analysis, which takes into consideration recovery factors relative to the geology of the location and similar reservoirs. Where applicable, the in dependent petroleum engineering firms examined data related to well spacing, including potential drainage from offsetting producing wells, in evaluating proved reserves of undrilled well locations.

The reserve audit performed by Ryder Scott Company, L.P. included certain properties selected by Maritech, including all of our significant properties described above, excluding the Main Pass Area properties, and represented approximately 70.6% of our total proved oil and gas reserve volumes as of December 31, 2010. The reserve audit performed by DeGolyer and MacNaughton included the Main Pass Area properties acquired in December 2007 and represented approximately 21.6% of our total proved oil and gas reserve volumes as of December 31, 2010. Ryder Scott Company, L.P. states in its audit report that they believe that the overall procedures and methodologies utilized by Maritech in preparing their estimates of proved reserves as of December 31, 2010 comply with current SEC regulations and that the overall proved reserves for the reviewed properties as estimated by Maritech were, in the aggregate, reasonable within the established audit tolerance guidelines of 10% as set forth in the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (SPE). DeGolyer and MacNaughton states in its audit report that the information relating to Maritech’s estimated proved reserves of oil, condensate, and natural gas contained in this Annual Report have been prepared in accordance with applicable accounting standards and SEC regulations. There were no limitations imposed or encountered by Maritech or the independent petroleum engineers in the preparation of our estimated reserves or in the performance of the reserve audits by the independent petroleum engineers.

Reserve information is prepared in accordance with guidelines established by the SEC. All of Maritech’s reserves are located in U.S. state and federal offshore waters in the Gulf of Mexico region and onshore Texas and Louisiana. The following table sets forth information with respect to our estimated proved reserves as of December 31, 2010:2011:

As of December 31, 2011, Maritech’s proved undeveloped reserves represented approximately 50.1% of Maritech’s total proved reserves. Maritech’s proved undeveloped reserves as of December 31, 2010, representrepresented approximately 10.6% of Maritech’s total proved reserves. Proved undeveloped reserves represented approximately 12.4% of Maritech total proved reserves as of December 31, 2009. During 2010, Maritech expended approximately $4.6 million of its development costs to convert approximately 55.9% of its proved undeveloped reserves at the beginning of the year to proved developed reserves. All of Maritech’s proved undeveloped reserves as of December 31, 2010,2011, have been classified as proved undeveloped for less than five years. Maritech has historically developed its proved undeveloped reserves over a reasonable period of time and anticipates it will do so in the future, utilizing our future operating cash flows, available working capital, and, if necessary, long-ter m borrowings. All of Maritech’s proved undeveloped reserves as of December 31, 2010, are scheduled to be developed prior to December 31, 2015.

For additional information regarding estimates of oil and gas reserves, including estimates of proved and proved developed reserves, the standardized measure of discounted future net cash flows, and the changes in discounted future net cash flows, see “Note R – Supplemental Oil and Gas Disclosures” in the Notes to Consolidated Financial Statements.

Maritech is not required to file, and has not filed on a recurring basis, estimates of its total proved net oil and gas reserves with any U.S. or non-U.S. governmental regulatory authority or agency other than the Department of Energy (DOE) and the SEC. The estimates furnished to the DOE have been consistent with those furnished to the SEC, however, they are not necessarily directly comparable, due to special DOE reporting requirements. In no instance havehas gross reserve volume information used to prepare the estimates for the DOE differed by more than five percent from the corresponding estimates reflected in total reserves reported to the SEC.

Item 3. Legal Proceedings.

We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Class Action Lawsuit

Between March 27, 2008, and April 30, 2008, two putative class action complaints were filed in the United States District Court for the Southern District of Texas (Houston Division) against us and certain former officers by certain stockholders on behalf of themselves and other stockholders who purchased our common stock between January 3, 2007, and October 16, 2007. The complaints assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On May 8, 2008, the Court consolidated these complaints as In re TETRA Technologies, Inc. Securities Litigation, No. 4:08-cv-0965 (S.D. Tex.). On June 16, 2010, defendants and plaintiff’s counsel reached a settlement agreement whereby all claims against defendants will be re leased in exchange for a payment of $8.25 million, which was subsequently paid by our insurers. On September 29, 2010, the Court approved the settlement and entered the Order and Final Judgment terminating the class action lawsuit.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in thea federal class action lawsuit and thewhich was settled during 2010. The claims are for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court con solidatedconsolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit wasCo-

On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit.lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff’s inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff’s counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. Our board is currently evaluatingOn August 22, 2011, the best courseCourt issued a Preliminary Approval Order preliminarily approving the settlement of actionthe suit as set forth in the Stipulation of Settlement dated August 12, 2011 (the Stipulation).

On October 17, 2011, the Court granted final approval of the settlement.

At this stage, it is impossible to predict the outcome of the derivative lawsuit or its impact upon us. We continue to believe that the allegations made in the derivative lawsuit are without merit, and we intend to continue to seek dismissal of and vigorously defend against this lawsuit. While a successful outcome cannot be guaranteed, we do not reasonably expect this lawsuit to have a material adverse effect.
Environmental Proceedings

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

In August of 2009, the Environmental Protection Agency (EPA), pursuant to Sections 308 and 311 of the Clean Water Act (CWA), served a request for information with regard to a release of zinc bromide that occurred from one of our transport barges on the Mississippi River on March 11, 2009. We timely filed a response to that request for information in August 2009. In January 2010, the EPA issued a Notice of Violation and Opportunity to Show Cause related to the spill. We met with the EPA in April 2010 to discuss potential violations and penalties. It has been agreed that no injunctive relief will be required. We have finalized a joint stipulation of settlement with the EPA whereby we are responsible for a penalty of $487,000, which has been submitted to the Department of Justice for approval. We expect to pay this penalty amount during the second qu arter of 2011 and expect the full amount to be covered by insurance.Item 4. Mine Safety Disclosures

Item 6. Selected Financial Data.

The following tables set forth our selected consolidated financial data for the years ended December 31, 2011, 2010, 2009, 2008, 2007, and 2006.2007. The selected consolidated financial data does not purport to be complete and should be read in conjunction with, and is qualified by, the more detailed information, including the Consolidated Financial Statements and related Notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operation” appearing elsewhere in this report. Please read “Item 1A. Risk Factors” beginning on page 1312 for a discussion of the material uncertainties which might cause the selected consolidated financial data not to be indicative of our future financial condition or results of operations. In December 2007, we sold our process se rvicesservices operations. In 2006, we made the decision to discontinue our Venezuelan fluids and production testing operations. In 2003, we made the decision to discontinue the operations of our Norwegian process services operations. During 2000, we commenced our exit from the micronutrients business. Accordingly, we have reflected each of the above operations as discontinued operations. During 2008, Maritech acquired certain oil and gas properties. During 2007, we completed the acquisition of two service companies and Maritech acquired certain oil and gas properties. During 2006, we completed the acquisitions of the operations of Epic Divers, Inc., Beacon Resources, LLC, and a heavy lift barge. During 2010, we recorded significant impairments of our oil and gas properties, a dive support vessel, and a calcium chloride manufacturing plant, as well as significant charges to earnings associated wit hwith adjustments to Maritech’s decommissioning liabilities. During 2008, we recorded significant impairments of oil and gas properties, goodwill, and other long-lived assets. During 2007, we recorded significant impairments of our oil and gas properties. During 2011, Maritech sold approximately 95% of the oil and gas proved reserves it held as of December 31, 2010. These acquisitions, dispositions, and impairments significantly impact the comparison of our financial statements for 20102011 to earlier years.

Business Overview

MarkedDuring the past two year period, a significant portion of the growth in the U.S. oil and gas industry activity has shifted from offshore operations to onshore. Led by the significant environmentaldramatic increase in activity in unconventional shale reservoirs throughout the United States, domestic onshore rig counts have increased significantly during this period. This trend has coincided with the continuing impact from the 2010 Macondo well accident in the U.S. Gulf of Mexico, which resulted in increased government regulation over offshore oil and gas operations. While the permitting delays affecting offshore drilling operations have been easing, offshore drilling activity levels in the Gulf of Mexico have been slow to recover and have only recently begun to trend toward pre-Macondo levels. These industry trends have significantly impacted our businesses. As evidenced by the unprecedented activity and revenue levels of our Production Testing segment, our U.S. onshore businesses have capitalized on the increased demand for domestic services, particularly in the most significant shale reservoirs, including the Haynesville, Eagle Ford, Marcellus, and others. Our Fluids Division segment has capitalized on the increased domestic onshore demand for its products and services, particularly water transfer and treatment services for fracturing operations. Our Compressco segment has also targeted these domestic growth regions for its compression-based production enhancement services. The continuing slow recovery of domestic offshore operations has affected our Fluids and Offshore Services businesses, but activity levels are increasing. However, the significant drilling activity for onshore shale gas reservoirs during the past two years, along with other demand factors, has resulted in declining prices for natural gas, particularly during the last half of 2011 and early 2012. Following the sale of substantially all of our Maritech segment’s oil and gas producing properties during 2011, the most significant direct impact on our revenues and operating cash flows resulting from decreased natural gas prices has been removed. However, the current low natural gas pricing environment, plus the continuing strength of crude oil prices, has resulted in a new trend by the industry toward oil drilling, which could once again impact certain of our businesses.

The strong performance by our Production Testing and Fluids segments contributed to our overall operating results for 2011. Production Testing segment revenues and profitability increased significantly compared to the prior year due to the increased domestic demand discussed above, although international activity increased as well. Fluids Division revenues and profitability also grew primarily due to increased domestic onshore product and service demand, although this segment also saw growth internationally. Our Offshore Services segment reported increased revenues during 2011 despite a soft pricing environment in the U.S. Gulf of Mexico. The July 2011 purchase of a new heavy lift derrick barge enables the Offshore Services segment to have increased capacity to serve the sustained long-term demand for heavy lift services, which we anticipate will continue due to the increased government regulation of offshore well abandonment and platform decommissioning that was enacted during 2010. Compressco also reported increased revenues primarily due to increased sales of compressor units compared to 2010. The Compressco segment’s profitability was negatively impacted, however, by increased operating expenses during 2011 and by increased public company costs associated with Compressco Partners following its initial public offering during June 2011. Increased Corporate Overhead costs were caused primarily by the recognized loss from liquidating our hedge derivative contracts, which we had used to hedge Maritech’s production cash flows. Maritech recognized significant gains on the sales of its oil and gas producing properties during 2011, but generated a significant loss for the year due to excess decommissioning costs associated with its remaining well abandonment and decommissioning obligations.

Our strong balance sheet was further enhanced during 2011, particularly as a result of the Macondo oil spill, the yearsale of 2010 ushered in a new regulatory climate for offshore energy operators. Despite the October 2010 lifting of a federally mandated deepwater drilling moratorium, offshoreMaritech’s oil and gas industry regulations,producing properties as administeredthese sales generated approximately $181.4 million of cash, net of adjustments. This strategic disposition has also allowed us to focus our capital expenditure priorities on our core service businesses, including the purchase of the above mentioned heavy lift barge by the newly formed BOEMRE, have resulted in delays and added regulatory costs to offshore projects. In addition, newly enacted regulations have also imposed requirements on operators, particularly affecting the abandonment and decommissioning of offshore oil and gas wells and production platforms. The new regulatory environment following the Macondo incident significantly affected our operations during 2010 and will continue to affect certain of our businesses going forward. Our Fluids Division revenues were n egatively affected during 2010 by the decreased activity caused by the moratorium and the ensuing permitting delays that continue to hamper the timing of offshore drilling projects by its customers. Until the first deepwater drilling permit was approved by BOEMRE on February 28, 2011, no permits to drill in the deepwater U.S. Gulf of Mexico had been issued since the Macondo oil spill. Our Gulf of Mexico Fluids Division activity will not fully recover until the pace of permitting reaches the pre-Macondo spill level. Our Offshore Services segment operations were also affected by project delays on its offshore operations during 2010, resulting from plug and abandonment permitting delays. Going forward, however,to fund the demand for abandonment and decommissioning services on offshore assets is expected to increase, perhaps significantly, as a resultcapital needs of new regulations. In particular,our growing Production Testing segment. Despite the NTL 2010-G05, or “Idle Iron Guidance,” issued by the BOEMRE in September 2010, will require  many operators t o accelerate decommissioning plans. Our Maritech segment operations were also affected, as the expected increased demand for abandonment and decommissioning services as a resultsale of the new regulations will increaseMaritech properties, we continue to utilize a significant portion of our operating cash flows to extinguish Maritech’s cost for these activities. The increased cost estimates for future Maritech abandonment andremaining decommissioning work, along with the costs incurredliabilities. We expended approximately $101.9 million on the significant amount ofdecommissioning work performed during 2010, contributed significantly2011, and a significant portion of the remaining decommissioning liability is anticipated to Maritech recordingbe extinguished during 2012. The June 2011 initial public offering of Compressco Partners (the Offering) generated approximately $54.0$42.2 million of charges for excess decommissioning costs duringnet Offering proceeds. Approximately $32.2 million of these Offering proceeds were used to repay to us certain intercompany note balances. Following the year.Offering, we own approximately 83% of Compressco Partners, and we continue to consolidate this subsidiary as part of our Compressco segment. In addition the increased abandonment and decommissioning cost estimates also contributed to Maritech recording a total of $63.8 million of oil and gas property impairments during the year. These charges were the most significant factors inavailability under our reporting a $43.7 million net loss for 2010.

Other than the impact from increased regulation of offshore oil and gas operations, our businesses also continued to be affected by other factors. Our Production Testing segment reported improved activity levels during 2010, as demand for U.S. onshore services increased during the year. Maritech revenue levels were enhanced primarily as a result of strong realized oil and natural gas commodity pricing as a result of hedge derivative contracts. However, Maritech’s natural gas hedge derivative contracts expired at the end ofbank revolving credit facility, we had

2010 and its remaining oil hedge derivative contracts are at prices below current market prices. The current levelsa consolidated cash balance of natural gas prices are expected to significantly reduce Maritech’s revenues and profitability going forward compared to 2010. Lower natural gas prices have also continued to affect Compressco’s operations, as revenue and profitability decreased compared toapproximately $204.4 million, although approximately $17.5 million of the prior year. While overall Fluids Division revenues were increased during 2010 as a result of production and sales of product from the El Dorado, Arkansas, calcium chloride manufacturing plant, profitability from the plant has been hampered by constrained production and resulting higher product costs per unit of production. Efforts to improve the plant’s performance are ongoing, but are not expected to impact its profitability until mid-2011. Consolidate d results were also affected by impairments of other long-lived assets, including the Lake Charles, Louisiana, calcium chloride manufacturing plant and certain Offshore Services assets, including one of its dive support vessels. Results were also affected by increased interest expense, as a significant amount of interest was capitalized during 2009 to long-term construction projects.

We continue to maintain a strongbalance is on Compressco Partners’ balance sheet and recent modifications to our long-term debt borrowings have improved our liquidity going forward. Operating cash flows during 2010 totaled $153.3 million, which was a 43.7% decrease comparedsatisfy its operating requirements as well as to 2009. Operating cash flows during 2010 reflect the decreased activity level of our Offshore Services segment comparedfund quarterly distributions pursuant to its record activity levels during 2009. A large portion of our operating cash flows during the past two years has been dedicated to the extinguishment of Maritech decommissioning liabilities for its offshore oil and gas properties, and this focus will continue in 2011. As discussed above, the estimated cost of future decommissioning work has increased significantly, partly as a result of increased regulations. Capital expenditures during 2010 totaled $107.7 million, all of which were fund ed from operating cash flows and existing cash balances. We continue to monitor our capital expenditure levels closely. In particular, due to a desire to conserve and reallocate capital, we have begun to decrease our investment in Maritech by suspending our search for oil and gas property acquisitions and decreasing our development activities. In addition, we are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and we are reviewing opportunities to sell Maritech oil and gas property packages to industry participants and other third parties. As part of this overall effort, a portion of Maritech’s properties was sold in February 2011.

During the fourth quarter of 2010, we sold $90 million of Series 2010 Senior Notes, using the proceeds from these borrowings to help retire $91.8 million of Series 2004 Senior Notes which were scheduled to mature in 2011. Also during the fourth quarter of 2010, we amended our bank revolving credit facility, decreasing the facility to $278 million and extending its scheduled maturity to 2015. We continue to carry no outstanding balance on our bank credit facility as of March 1, 2011. With our strong cash position and borrowing capacity, we continue to review strategic acquisitions and growth opportunities for our businesses.partnership agreement.

Future demand for our products and services depends primarily on activity in the oil and natural gas exploration and production industry, particularly including the level of expenditures for the exploration and production of oil and natural gas reserves and for the plugging and decommissioning of abandoned oil and gas properties. U.S. onshore domestic oil and gas industry expenditures, as indicated by rig count statistics and other measures, have recently increased to late 2008 levels. Industry expenditure levels had been in decline during the past two years in response to the general uncertainty regarding availability of capital resources during the recent global recession and due to oil and natural gas price volatility. U.S. offshore drilling activity, which also began increasing during the first half of 2010, was then significantly reduced as a result of the o ffshore drilling moratorium which followed the Macondo oil spill. Post-moratorium offshore rig counts have recently begun to increase, however, activity levels are still far below pre-moratorium levels.properties. The growth of certain of our businesses remainsmay become hampered by the current pricing levels of natural gas, particularly as compared to crude oil. However, we still believe that there are growth opportunities for our products and services in the U.S. and internationalforeign markets, supported primarily by:
·  applications for many of our products and services in the exploitation and development of shale reservoirs;
 
·  increased regulatory requirements governing the abandonment and decommissioning work on aging offshore platforms and wells in the Gulf of Mexico;
 
·  increases in technologically-driventechnologically driven deepwater oil and gas well completions in the Gulf of Mexico;
·  applications for many of our products and services in the exploitation and development of shale gas reservoirs; and
 
·  increasing international oil and gas exploration and development activities.

Our Fluids Division generates revenues and cash flows by sellingmanufacturing and marketing clear brine completion fluids (CBFs), additives, and providingother associated products to the oil and gas industry for use in well drilling, completion, and workover operations in the United States and in certain countries in Latin America, Europe, Asia, the Middle East, and Africa. The Fluids Division also provides a broad range of associated services, including onsite fluids filtration, handling, and recycling; wellbore cleanup; fluid engineering consultation; completion fluids additives and fluid management services; as well as high volume water transfer and associated products and technical engineeringtreatment services to U.S. and international exploration and production companies.for fracturing operations. In addition, the Fluids Division also providesmarkets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry.non-energy markets. Fluids Division revenues increased 22.5%10.2% during 20102011 compared to the prior year,2010 primarily due primarily to the commencement of operation of our El Dorado, Arkansas, calcium chloride plant. The El Dorado plant began initial production in late 2009 and produces liquid and dry (flake) calcium chloride as part of our manufactured products operation. In addition, the Fluids Divisi on’s completion products and services business generated increased revenues, reflecting the increasing U.S. onshore industry activity and demand forinternational CBF products during the year. This increase occurred despite the negative impact of the offshore drilling moratorium, which significantly decreasedproduct sales. Domestic offshore activity during much of 2010. We estimate that the impact of the moratorium negatively affected our Fluids Division revenues by approximately $20 to $22 million during the last half of 2010. The overall outlook for the Division’s completion services business continueslevels continue to be dependent on the levelimpacted negatively as a result of oil and gas drilling activity, particularly in the Gulf of Mexico, which has remained flat or has decreased during the past several years, due largely to the maturity of the producing fields in the heavily developed portions of the Gulf of Mexico. However, weMexico as well as uncertain regulations governing offshore drilling activities following the April 2010 Macondo accident. Offshore oil and gas drilling activity levels have recently improved, but are still below pre-Macondo levels. This decrease in offshore activity has been largely offset, however, by increased domestic onshore operations, including increased revenues from frac water services. We anticipate continued increases in industry spending in 2011,2012, particularly given the current levels of crude oil prices. Also, the Division is at temptingplans to continue to capitalize on the current industry trend toward drilling deepwater wells that generally require greater volumes of more expensive CBFs. In addition, we continue to pursue specific international opportunitiesdeveloping unconventional onshore shale reservoirs, where industry spending levels from major energy customers and national oil companies have generally been more stable.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. Offshore Services generates revenues and cash flows by performing (1) downhole and subsea services such as plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services, including offshore platform removal and hurricane damage remediation, and (3) diving services involving conventional and saturated air diving and the operation of several dive support vessels. The services provided by the Offshore Services segment are marketed primarily in the Gulf Coast region of the U.S., including offshore, inland waters, and in certain onshore locations. Gulf of Mexico platform decommissioning and well abandonment activity levels are driven primarily by BOEMRE regulations; the age of producing fields; production plat forms and other structures; oil and natural gas commodity prices; sales activity of mature oil and gas producing properties; and overall oil and gas company activity levels. Recent regulations enacted by the BOEMRE governing the timing of abandonment and decommissioning of nonproductive wells and unused offshore platforms are expected to increase the demand for the Offshore Services segment, perhaps significantly, over the next several years. Given the increased cost to insure offshore properties for windstorm damage coverage and to reduce the risk from future storms, many oil and gas operators, including Maritech, are accelerating their plans to abandon and decommission their offshore wells and platforms. Offshore Services revenues decreased by 22.5% during 2010 compared to the revenue level experienced during 2009, when increased utilization by the segment’s diving, abandonment, heavy lift, and cutting services businesses as a result of the high demand following the 2005 and 2008 hurricanes, resulted in record activity levels. For the reasons described, the Offshore Services segment expects strong demand for its products and services to continue, however, the segment anticipates its overall activity in 2011 will again be less than the record levels experienced during 2009.

Through Maritech, the Offshore Division acquires, manages, explores, and develops oil and gas properties in the offshore, inland water, and onshore region of the Gulf of Mexico and generates revenues and cash flows from the sale of the associated oil and natural gas production volumes. Maritech periodically acquires properties for their exploration and development potential. Maritech’s revenues during 2010have significantly increased by 13.3% compared to 2009 due to increased realized oil and gas commodity prices and despite decreased production volumes during the year. The increase in realized prices was primarily due to the impact of commodity hedge derivative contracts. However, the derivative contracts with the most favorable terms compared to current market prices expired at the end of 2010. Maritech continues to perform a significant amount of plugging, abandonment, and decommissioning efforts on its offshore oil and gas properties, particularly as part of its strategy to reduce its risk from hurricanes and in response to the increased cost of windstorm insurance coverage. Maritech has historically grown its operations by acquiring and developing oil and gas property interests located in the offshore, inland waters, and onshore U.S. Gulf Coast region. However, due to a desire to conserve and reallocate capital, we have begun to decrease our investment in Maritech by suspending our search for oil and gas property acquisitions and decreasing our
39

development activities. In addition, we are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and we are reviewing opportunities to sell Maritech oil and gas property packages to industry participants and other third parties. As part of this overall effort, in late February 2011, Maritech sold a group of properties that accounted for approximately 11.4% of its proved reserves as of December 31, 2010.past two years.

Our Production Enhancement Division consists of two operating segments: the Production Testing segment and the Compressco segment. The Production Testing segment generates revenues and cash flows by performing post-frac flow back pressure and volumewell testing of onshore and offshore oil and gas wells and by providing reservoir data necessary to enable operators to quantify reserves, optimize production, and minimize oil and gas reservoir damage. The primary testing markets served include many of the major oil and gas basins in the United States, as well as in Mexico and South America, Northern Africa, the Middle East, and Asia. The Division’s production testing operations are generally driven by the demand for natural gas and oil and the resulting drilling and completion activities in the markets where the Production Testing segment serves. Production Testing segment’ ;ssegment’s revenues increased 33.8%34.4% in 20102011 compared to 2009,2010, primarily due to increased demand in the United States.States, and particularly due to increased activity in unconventional shale reservoirs. Given the continuing increase in drilling activity, we anticipate that demand for our production testing services will continue to increase in 20112012 compared to 2010.2011.

Compressco generates revenues and cash flows by performing wellhead compression-based production enhancement services throughout mostmany of the onshore producing regions of the United States, as well as certain onshore basins in Mexico, Canada, Mexico, South America, Europe, Asia, and other international locations. Demand for wellhead compression services is primarily driven by the need to boost production in certain mature gas wells with declining production. Compressco segment revenues decreased 10.5%increased 17.8% in 20102011 as compared to 2009,2010, primarily due to decreasedincreased sales of compressor units as well as an increase in demand
34

for production enhancement services, as a result of lowerparticularly in Latin America. Given the recent decrease in domestic natural gas prices, the near-term growth of Compressco’s domestic service revenues during 2012 may be negatively affected.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. Offshore Services generates revenues and cash flows by performing (1) downhole and subsea oil and gas services such as well as from increased competition. Givenplugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services, including utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services. The services provided by the recent increasesOffshore Services segment are marketed to offshore operators primarily in the U.S. Gulf Coast region. Gulf of Mexico platform decommissioning and well abandonment activity levels are driven primarily by BSEE regulations; the age of producing fields; production platforms and other structures; oil and natural gas prices, we anticipate Compressco’scommodity prices; sales activity of mature oil and gas producing properties; and overall oil and gas company activity levels. Regulations enacted during 2010 by the BOEMRE governing the timing of abandonment and decommissioning of nonproductive wells and unused offshore platforms are expected to increase the demand for the Offshore Services segment over the next several years. Given the increased cost to insure offshore properties for windstorm damage coverage and to reduce the risk from future storms, some oil and gas operators, including Maritech, are accelerating their plans to abandon and decommission their offshore wells and platforms. Offshore Services revenues increased by 4.8% during 2011 revenues and cash flows will increase modestly compared to 2010, particularly asprimarily due to increased abandonment and decommissioning work performed. In July 2011, the Offshore Services segment purchased a new 1,600-metric-ton heavy lift derrick barge, which we also continuehave named the TETRA Hedron. This vessel was placed  into service during the fourth quarter of 2011 and significantly increases the Offshore Services segment’s heavy lift capacity to serve customers with heavier structures.

The sales of almost all of Maritech’s oil and gas producing properties during 2011 have essentially removed us from the oil and gas exploration and production business. During late 2010, we elected to explore strategic alternatives to our ownership of Maritech in order to conserve and reallocate capital to, and allow us to focus on, our remaining core businesses. As part of this strategic decision, beginning in February 2011, Maritech began selling oil and gas property packages to industry participants and other third parties. Maritech is continuing to seek new U.S .the sale of its remaining oil and international markets for Compressco operations.gas producing properties during 2012. As a result of these sales of oil and gas properties, Maritech’s revenues during 2011 decreased by 58.7% compared to 2010 and are expected to be minimal going forward. Maritech continues to perform a significant amount of plugging, abandonment, and decommissioning efforts on its remaining offshore wells, facilities and production platforms.

Critical Accounting Policies and Estimates

This discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements. We prepared these financial statements in conformity with United States generally accepted accounting principles. In preparing our consolidated financial statements, we make assumptions, estimates, and judgments that affect the amounts reported. We base these estimates on historical experience, available information, and various other assumptions that we believe are reasonable. We periodically evaluate these estimates and judgments, including those related to potential impairments of long-lived assets (including goodwill), the collectability of accounts receivable, and the current cost of future abandonment and decommissioning obligations. “Note B – Summary of Significant Accounting Policies” to the Consolidated Financial Statements contains the accounting policies governing each of these matters. Our estimates are based on historical experience and on future expectations which we believe are reasonable. The fair values of large portions of our total assets and liabilities are measured using significant unobservable inputs. The combination of these factors forms the basis f orfor our judgments made about the carrying values of assets and liabilities that are not readily apparent from other sources. These judgments and estimates may change as new events occur, as new information is acquired, and as changes in our operating environment are encountered. Actual results are likely to differ from our current estimates, and those differences may be material. The following critical accounting policies reflect the most significant judgments and estimates used in the preparation of our financial statements.

Impairment of Long-Lived Assets

The determination of impairment of long-lived assets is conducted periodically whenever indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is
35

based on our judgments as to the future operating cash flows to be generated from these assets throughout their estimated useful lives. If an impairment of a long-lived asset is warranted, we estimate the fair value of the asset based on a present value of these cash flows or the value that could be realized from disposing of the asset in a transaction between market participants. The oil and gas industry is cyclical, and our estimates of the amount of future cash flows, the period over which these estimated future cash flows will be generated, as well as the fair value of an impaired asset, are imprecise. Our failure to accurately estimate the sethese future operating cash flows or fair values could result in certain long-lived assets being overstated, which could result in impairment charges in periods subsequent to the time in which the impairment indicators were first present. Alternatively, if our estimates of future operating cash flows or fair values are understated, impairments might be recognized unnecessarily or in excess of the appropriate amounts. Our estimates of
40

operating cash flows and fair values for assets impaired have generally been accurate. Although the majority of our impairments of long-lived assets have typically related to oil and gas properties, (see separate discussion below), during 2010 we recorded other long-lived asset impairments of $25.1 million. Given the current volatileuncertain economic environment, the likelihood of additional material impairments of long-lived assets in future periods is higher due to the possibility of further decreased demand for our products and services.

Impairment of Goodwill

The impairment of goodwill is also assessed whenever impairment indicators are present, but not less than once annually. TheBeginning in 2011, the annual assessment for goodwill impairment begins with a qualitative assessment of whether it is performed for each reporting unit and consists of a comparison of“more likely than not” that the carrying amountfair value of each reporting unit to our estimationis less than its carrying value. This qualitative assessment requires the evaluation, based on the weight of evidence, of the significance of all identified events and circumstances for each reporting unit. Based on this qualitative assessment, we determined that it was not “more likely than not” that the fair values of any of our reporting units were less than their carrying values as of December 31, 2011. If the qualitative analysis indicates that it is “more likely than not” that a reporting unit’s fair value is less than its carrying value, the resulting goodwill impairment test would consist of thata two-step accounting test performed on a reporting unit.unit basis. If the carrying amount of the reporting unit exceeds its estimated fair value, an impairment loss is calculated by comparing the carrying amount of the reporting unit’s goodwill to our estimated implied fair value of that goodwill. Our estimates of reporting unit fair value, if required, are imprecise and are subject to our estimates of the future cash flows of each business and our judgment as to how these estimated cash flows translate into each business’ estimated fair value. These estimates and judgments are affected by numerous factors, including the general economic environment at the time of our assessment, which affects our overall market capitalization. If we over estimate the fair value of our reporting units, the balance of our goodwill asset may be overstated. Alternatively, if our estimated reporting unit fair values are understated, impairments might be recognized unnecessarily or in excess of the appropriate amounts. During the fourth quarter of 2008, due to changes in the global economic environment which affected our stock price and market capitalization, we recorded an impairment of goodwill of $47.1 million. We believe our estimates of the fair value for each reporting unit are reasonable. However, given the current volatile economic environment, the likelihood of additional material impairments of goodwill in future periods is higher.

As of December 31, 2010,2011, our Offshore Services, Production Testing, and Compressco reporting units reflect goodwill in the amounts of $3.8$3.9 million, $23.0 million, and $72.2 million, respectively. The fair values of our Offshore Services and Production Testing reporting units significantly exceed their carrying values. However, because the estimated fair value of our Compressco reporting unit currently exceeds its carrying value by approximately 13.3%, there is a reasonable possibility that Compressco’s goodwill may be impaired in a future period and the amount of such impairment may be material. Specific uncertainties affecting the estimated fair value of our Compressco reporting unit include the prices received by Compressco’s customers for natural gas production, the rate of future growth of Compressco’s business, and the need and timing of the full resumption of the fabrication of new Compressco compressor units. In addition, Compressco’s Mexico operations may continue to be disrupted by security issues in that country. The demand for Compressco’s wellhead compression services continues to be decreased compared to early 2008 levels and negatively affected by the current economic environment. A decrease in natural gas prices could have a further negative effect on the fair value of our Compressco reporting unit.

Oil and Gas Properties

Maritech accounts for its interests in oil and gas properties using the successful efforts method, whereby costs incurred to drill and equip development wells, including unsuccessful development wells, are capitalized, and costs related to unsuccessful exploratory wells are expensed as incurred. All capitalized costs are accumulated and recorded separately for each field and are depleted on a unit-of-production basis, based on the estimated remaining proved oil and gas reserves of each field. Oil and gas properties are assessed for impairment in value on an individual field basis, whenever indicators become evident, with any impairment charged to expense. Accordingly, Maritech’s results of operations may be more volatile compared to those oil and gas exploration and production companies who account for their operations using the full-cost me thod. Due to the impact of changing oil and gas prices, results of drilling and development efforts, and increased estimated decommissioning liabilities (see discussion below), Maritech has recorded oil and gas property impairments and dry hole costs, and during 2008, 2009, and 2010 these impairment charges were significant. Maritech periodically purchases oil and gas properties and assumes the associated well abandonment and decommissioning liabilities. Any significant differences in the actual amounts of oil and gas production cash flows produced or decommissioning costs incurred compared to the estimated amounts recorded will affect our anticipated profitability. Given the volatility of oil and natural gas prices, we are more likely to record additional significant impairments in future periods.
 
41

The process of estimating oil and gas reserves is complex, requiring significant decisions and assumptions in the evaluation of available geological, geophysical, engineering, and economic data for each reservoir. As a result, these estimates are inherently imprecise. Actual future production, cash flows, development expenditures, operating and abandonment expenses, and quantities of recoverable oil and gas reserves may vary substantially from those initially estimated by Maritech. Any significant variance in these assumptions could result in significant upward or downward revisions of previous estimates, as reflected in our annual disclosure of the estimated quantity and value of our proved reserves. In previous years, we have reflected revisions to our previous estimates of reserve quantities and values, and in some years, these revisions have b een significant. It is possible we will have additional revisions to our estimated quantities of proved reserves in future periods.

Decommissioning Liabilities

Maritech’s decommissioning liabilities are established based on what it estimates a third party would charge to plug and abandon the wells, decommission the pipelines and platforms, and clear the sites. These well abandonment and decommissioning liabilities (referred to as decommissioning liabilities) are recorded net of amounts allocable to joint interest owners anticipated insurance recoveries, and any contractual amounts to be paid by the previous owners of the property. In estimating the decommissioning liabilities, we perform detailed estimating procedures, analysis, and engineering studies. Whenever practical, Maritech settles these decommissioning liabilities by utilizing the services of its affiliated companies to perform well abandonment and decommissioning work. This practice saves us the profit margin that a third party would charge for s uchsuch services. When these services are performed by an affiliated company, all recorded intercompany revenues are eliminated in the consolidated financial statements. Any difference between our own internal costs to settle the decommissioning liability and the recorded liability is recognized in the period in which we perform the work. The recorded decommissioning liability associated with a specific property is fully extinguished when the property is completely abandoned. Once a Maritech well abandonment and decommissioning
36

project is performed, any remaining decommissioning liability in excess of the actual cost of the work performed is recorded as a gain and is included in earnings in the period in which the project is completed. Conversely, actual costs in excess of the decommissioning liability are charged against earnings in the period in which the work is performed.

We review the adequacy of our decommissioning liabilities whenever indicators suggest that either the amount or timing of the estimated cash flows underlying the liabilities have changed materially. The estimated timing of these cash flows is determined by the productive life of the associated oil and gas property, which is based on the property’s oil and gas reserve estimates. The amount of cash flows necessary to abandon and decommission the property is subject to changes due to seasonal demand, increased demand following hurricanes, regulatory changes, and other general changes in the energy industry environment. Accordingly, the estimation of our decommissioning liabilities is imprecise. Following the late 2010 issuance by the BOEMRE of NTL 2010-G05 “Idle Iron Guidance” regulations, and due to other factors,the estimate for Maritech’s decommissioning liabilities increased significantly. In addition, Maritech significantly adjus tedhas adjusted its decommissioning liabilities as of December 31, 2010. Largelyduring 2010 and 2011 as a result of these adjustments,increased estimates, as well as a result of the cost of significant abandonment and decommissioning work performed during the year,year. Maritech recorded approximately $30.2$54.0 and $78.4 million of increased excess decommissioning expense during 2010 and 2011, respectively, associated with work performed or to be performed on nonproductive oil and gas properties. In addition, adjustments to decommissioning liabilities associated with productive properties were capitalized to oil and gas properties and contributed significantly to Maritech recording approximately $52.4 million of increased oil and gas property impairments during 2010 compared to the prior year.2009. The estimation of the decommissioning liabilities associated with the two remaining Maritech offshore platforms that were destroyed during the 2005 and 2008 hurricanes is particularly difficult due to the non-routine nature of the efforts required. The actual cost of performing Maritech’s well abandonment and decommis sioningdecommissioning work has often exceeded our initial estimate of Maritech’s decommissioning liabilities and has resulted in charges to earnings in the period the work is performed or when the additional liability is determined. During 2008, 2009, and 2010, the amount of charges to earnings as a result of costs of work performed being in excess of our estimated liabilities has been significant. To the extent our decommissioning liabilities are understated, additional charges to earnings may be required in future periods.

Revenue Recognition

We generate revenue on certain well abandonment and decommissioning projects under contracts which are typically of short duration and that provide for either lump-sum turnkey charges or specific time,
42

material, and equipment charges, which are billed in accordance with the terms of such contracts. With regard to turnkeylump sum contracts, revenue is recognized using the percentage-of-completion method based on the ratio of costs incurred to total estimated costs at completion. The estimation of total costs to be incurred may be imprecise due to unexpected well conditions, delays, weather, and other uncertainties. Inaccurate cost estimates may result in the revenue associated with a specific contract being recognized in an inappropriate period. Total project revenue and cost estimates for turnkeylump sum contracts are reviewed periodically as work progresses, and adjustments are reflected in the period in which such estimates are revised. Provisions for estimated losses on such contracts are made in the period such losses are determined. Despite the uncerta intiesuncertainties associated with estimating the total contract cost, our recognition of revenue associated with these contracts has historically been reasonable.

Our Production Testing segment is party to a South American technical management contract which contains multiple deliverables, including the delivery of equipment and the performance of service milestones. While the contract provides contract-determined values associated with each deliverable, the recognition of revenue is determined based on the realized market values received by the customer as well as by the realizability of collections under the contract. The determination of realized market values is supported by objective evidence whenever possible, but may also be determined based on our judgments as to the value of a particular deliverable.

Bad Debt Reserves

Reserves for bad debts are calculated generally and on a specific identification basis, whereby we estimate whether or not specific accounts receivable will be collected. Such estimates of future collectability may be incorrect, which could result in the recognition of unanticipated bad debt expenses in future periods. A significant portion of our revenues come from oil and gas exploration and production companies, and historically our estimates of uncollectible receivables have proven reasonably accurate. However, if due to adverse circumstances, certain customers are unable to repay some or all of the amounts owed us, an additional bad debt allowance may be required, and such amount may be material.

37

Income Taxes

We provide for income taxes by taking into account the differences between the financial statement treatment and tax treatment of certain transactions. Deferred tax assets and liabilities are recognized for the anticipated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis amounts. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date. This calculation requires us to make certain estimates about our future operations, and many of these estimates of future operations may be i mprecise.imprecise. Changes in state, federal, and foreign tax laws, as well as changes in our financial condition, could affect these estimates. In addition, we consider many factors when evaluating and estimating income tax uncertainties. These factors include an evaluation of the technical merits of the tax position as well as the amounts and probabilities of the outcomes that could be realized upon ultimate settlement. The actual resolution of those uncertainties will inevitably differ from those estimates, and such differences may be material to the financial statements. Our estimates and judgments associated with our calculations of income taxes have been reasonable in the past, however, the possibility for changes in the tax laws, as well as the current economic uncertainty, could affect the accuracy of our income tax estimates in future periods.

Acquisition Purchase Price Allocations

We account for acquisitions of businesses using the purchase method, which requires the allocation of the purchase price based on the fair values of the assets and liabilities acquired. We estimate the fair values of the assets and liabilities acquired using accepted valuation methods, and, in many cases, such estimates are based on our judgments as to the future operating cash flows expected to be generated from the acquired assets throughout their estimated useful lives. We have completed several acquisitions during the past several years and have accounted for the various assets (including intangible assets) and liabilities acquired based on our estimate of fair values. Goodwill represents the excess of acquisition purchase price over the estimated fair values of the net assets acquir ed.acquired. Our estimates and judgments of the fair value of
43

acquired businesses are imprecise, and the use of inaccurate fair value estimates could result in the improper allocation of the acquisition purchase price to acquired assets and liabilities, which could result in asset impairments, the recording of previously unrecorded liabilities, and other financial statement adjustments. The difficulty in estimating the fair values of acquired assets and liabilities is increased during periods of economic uncertainty.

Stock-BasedEquity-Based Compensation

We estimate the fair value of share-based payments of stock options using the Black-Scholes option-pricing model. This option-pricing model requires a number of assumptions, of which the most significant are: expected stock price volatility, the expected pre-vesting forfeiture rate, and the expected option term (the amount of time from the grant date until the options are exercised or expire). Expected volatility is calculated based upon actual historical stock price movements over the most recent periods equal to the expected option term. Expected pre-vesting forfeitures are estimated based on actual historical pre-vesting forfeitures over the most recent periods for the expected option term. All of these estimates are inherently imprecise and may result in compensation cost being recorded that is materially different from the actual fair value o fof the stock options granted. While the assumptions for expected stock price volatility and pre-vesting forfeiture rates are updated with each year’s option-valuing process, we experienced significant revisions during 2011 primarily due to the reduction in the workforce of our Maritech segment. Prior to 2011, there have not been significant revisions made in these estimates to date.estimates.

Consolidated revenues during 2011 decreased compared to the prior year, as the decrease in Maritech revenues resulting from sales of almost all of its oil and gas producing properties during the year more than offset the growth in revenues from each of our other segments. In particular, revenues from our Production Testing segment increased significantly due to increased domestic demand and higher activity in Mexico. In addition, Fluids segment revenues increased due to CBF sales activity in the regions we serve as well as increased calcium chloride sales activity, primarily domestically. Our Compressco segment reported increased revenues, due largely to increased sales of compressor units during the year, but also due to increased international and domestic demand for its compression based services. Our Offshore Services segment also reported increased revenues due to increased well abandonment and decommissioning service activity during 2011 compared to the prior year. Overall gross profit increased primarily due to higher profitability from our Production Testing and Fluids segments, both of which reflect the increased demand for their domestic onshore products and services. Our Offshore Services segment also reflected increased gross profit, primarily due to the impairment of one of its dive service vessels during 2010.
Consolidated general and administrative expenses increased during 2011 compared to the prior year due to approximately $6.9 million of increased salaries, benefits, and other employee-related costs, partially due to increased headcount. This increase was despite a $0.9 million decrease in equity-based compensation. In addition, general and administrative expenses also increased due to approximately $2.3 million of increased professional fee expenses, $2.1 million of decreased billings to joint owners for Maritech administrative overhead, and $1.0 million of increased bad debt expense, primarily due to the reversal of $1.0 million of bad debt expense during the prior year period. In addition, insurance, taxes, and other general expenses increased by approximately $0.8 million.
Net consolidated interest expense decreased during 2011 primarily due to increased interest income resulting from increased cash investments.

Consolidated gains on sales of assets increased significantly during 2011, primarily due to the sale of Maritech oil and gas producing properties, particularly the May 2011 sale of properties to Tana.
39

Consolidated other expense was $13.2 million during 2011 and was primarily due to the $14.2 million charge to expense upon the liquidation of commodity derivative swap contracts in connection with the decision to sell Maritech oil and gas producing properties. In addition, current year other expense includes approximately $1.3 million of increased foreign currency losses. These increases were partially offset by approximately $2.2 million of decreased other expense compared to the prior year period primarily due to a $2.8 million premium that was charged during 2010 in connection with the early repayment of the 2004 Senior Notes.

Our provision for income taxes during 2011 increased due to our increased earnings compared to the prior year period.

The increase in Fluids Division revenues during 2011 compared to 2010 was primarily due to $17.5 million of increased product sales revenues. This increase was due to $10.7 million of increased CBF product sales revenues, as increased activity internationally, particularly in Brazil, more than offset a decrease in domestic offshore activity and pricing. Domestic offshore activity levels continue to be reduced as a result of the uncertain regulations governing offshore drilling activities following the April 2010 Macondo accident. Also contributing to the increased revenues was $6.8 million of increased sales of calcium chloride and other manufactured products, primarily from our El Dorado, Arkansas, calcium chloride plant. Increased onshore domestic activity levels, particularly associated with unconventional shale reservoir markets, resulted in approximately $10.7 million of increased service revenues, including increased revenues from frac water services.

Our Fluids Division gross profit increased during 2011 compared to 2010, primarily as a result of the increased gross profit from our chemicals manufacturing operations resulting from the 2010 impairment of the $7.2 million carrying value of the Division’s Lake Charles, Louisiana, calcium chloride plant. Due to the market pricing for calcium chloride and the uncertain supply of raw materials needed to operate the plant on economic terms, the expected operating cash flows of the plant were insufficient to cover the plant’s carrying value. In addition, startup costs and production inefficiencies during 2010 negatively affected the profitability of our El Dorado, Arkansas, plant. While many of these production inefficiencies were mitigated during 2011, we continue to seek ways to improve the plant’s operating performance. Associated with these plant operational inefficiencies, in March 2011, we filed a lawsuit in Union County, Arkansas, seeking to recover damages related to certain design and other services provided in connection with the construction of the El Dorado plant. In addition to the improved gross profit from our chemicals manufacturing operations, gross profit generated from the increased frac water and other services during 2011 more than offset the decreased gross profit from sales of CBFs, that were primarily a result of the decreased domestic offshore market.

Fluids Division income before taxes increased compared to the prior year period due to the increase in gross profit discussed above and an increase in other income, which more than offset the increased administrative costs. Fluids Division administrative costs increased due to increased salary and employee benefit costs and due to increased professional fees.

Production Testing revenues increased significantly during 2011 due to an increase of approximately $30.6 million in domestic revenues. This increase was a result of increased domestic onshore oil and gas drilling activity, as reflected by rig count data. In particular, the Production Testing segment is capitalizing on the increased domestic onshore activity associated with unconventional shale drilling in many of the regions it serves. In addition, international revenues increased by approximately $5.3 million, primarily due to increased PEMEX activity in Mexico.

The increase in Production Testing gross profit during 2011 was primarily due to the increased domestic activity discussed above and the increased efficiencies at the higher activity levels. Gross profit on international Production Testing operations also increased during 2011 primarily due to increased profitability on a South American technical management contract.

Production Testing income before taxes increased due to the increased gross profit discussed above. These increases were partially offset by increased administrative expenses primarily from increased salary and other employee-related costs during the 2011 period. In addition, the Production Testing segment reflected increased office and professional fees, as well as increased bad debt expense, particularly associated with the segment’s Libyan operations.

The increase in Compressco revenues was due to an increase of approximately $9.2 million of revenues from sales of compressor units and parts during 2011 compared to 2010. This increase was primarily due to sales of compressor units to two specific customers, and the level of compressor unit sales going forward is expected to decrease compared to 2011. Compressco service revenue increased by approximately $5.3 million primarily due to increased international demand for compression services, particularly in Latin America. To a lesser extent, service revenue also increased due to increased domestic demand. Compressco’s continuing growth domestically could be negatively affected by current low natural
41

gas prices. In addition, international growth could be hampered by conditions in Mexico, where customer budgetary issues and security disruptions have had a negative impact on activity levels during the past two years. Compressco continues to operate at reduced levels of fabrication of new compressor units for its service fleet and expects to do so until demand for its services increases and inventories of available units are reduced.

Compressco gross profit increased during 2011 compared to 2010 primarily due to the increased sales of compressor units. In addition, gross profit on international service revenues increased, particularly in Latin America. Gross profit on domestic service revenues decreased despite the increase in revenues, due to increased operating expenses. Our Compressco segment continues to seek ways to reduce its operating expenses in the future.
Income before taxes for Compressco decreased during 2011 compared to 2010, despite the increase in gross profit described above, primarily due to increased administrative expense. Compressco administrative expenses reflect the increased professional fee expenses and increased administrative staff as a result of Compressco Partners being a separate public limited partnership and the allocation of a portion of our corporate administrative expenses to Compressco Partners pursuant to the Omnibus Agreement which we and Compressco Partners executed in connection with Compressco Partners’ initial public offering. In addition, the Compressco segment had increased other expense primarily due to increased foreign currency losses.

Revenues from our Offshore Services segment increased during 2011 compared to 2010 primarily due to increased decommissioning, abandonment and dive services activity. These increases were partially offset by decreased cutting services and wireline activity, and the impact throughout 2011 of a softer pricing environment. In addition, during May 2011, we sold our onshore abandonment operations, although this sale is not expected to significantly reduce our revenues in the future. In July 2011, we purchased a new heavy lift derrick barge (which we named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. With this vessel, which was placed into service in the Gulf of Mexico during the fourth quarter of 2011, our Offshore Services segment has significantly increased its heavy lift capacity, enabling us to better serve the Gulf of Mexico decommissioning market and to serve customers with heavier structures. We continue to anticipate that the NTL 2010-G05 “Idle Iron Guidance” regulations issued during 2010 will increase the future demand for well abandonment and decommissioning services to be performed by our Offshore Services segment. Approximately $65.0 million of Offshore Services revenues were from work performed for Maritech during 2011, compared to $62.5 million of such work during 2010. These intercompany revenues are eliminated in consolidation. Despite the sale of Maritech’s oil and gas producing properties, a significant amount of abandonment and decommissioning work remains for Maritech, and a majority of this work is scheduled to be performed during 2012.

Gross profit for the Offshore Services segment during 2011 increased as compared to 2010 due to approximately $15.3 million of impairments during 2010, primarily from the impairment of the carrying value of the Epic Diver, a dive support vessel owned by our Epic Diving & Marine Services
42

subsidiary. During 2010, we determined that this vessel was no longer strategic to the segment’s plan to serve its markets. While the purchase of the TETRA Hedron heavy lift derrick barge is expected to generate increased profitability for our decommissioning operations going forward, gross profit for 2011 was decreased by approximately $6.2 million for the due diligence, inspection, and start up costs incurred during 2011 prior to the vessel being placed into service during the fourth quarter. Overall segment profitability was also affected by a lower pricing environment during 2011, partly due to increased competition.

Offshore Services segment income before taxes increased primarily due to the increase in gross profit described above. In addition, Offshore Services segment administrative costs decreased primarily due to decreased salaries and employee-related, office expenses, insurance, and other general costs. Offshore Services segment income before taxes also increased due to the increase in other income, which was primarily generated from the sale of onshore abandonment operations during 2011.

Maritech revenues decreased significantly during 2011 compared to 2010, due to the sale during the current year period of approximately 95% of Maritech’s total proved oil and gas reserves as of December 31, 2010. The most significant sale of oil and gas producing properties was on May 31, 2011, when Maritech completed the sale to Tana of oil and gas properties that collectively represented approximately 79% of Maritech’s December 31, 2010, total proved reserves. As a result of these sales, decreased production volumes resulted in decreased revenues of approximately $95.4 million. In addition to the impact of decreased production, Maritech revenues decreased approximately $20.5 million primarily due to decreased realized prices of Maritech’s natural gas production. Maritech had previously hedged a portion of its expected production cash flows by entering into derivative hedge contracts and its contracts hedging its oil production extended through 2011. However, Maritech’s natural gas hedges expired at the end of 2010. Maritech’s average natural gas price received during 2011 was $4.39/MMBtu compared to the $8.55/Mcf average realized price received during 2010. In April 2011, in connection with the planned sale of oil and gas producing properties to Tana, we liquidated the oil derivative hedge contracts. As a result, beginning April 2011, Maritech’s remaining oil and gas production cash flows are no longer hedged. Including the impact of its oil hedge contracts through March 2011, Maritech reflected average realized oil prices during 2011 of $102.34/barrel compared to $96.62/barrel during 2010. Following the above mentioned sales of producing properties, Maritech revenues are expected to continue to be minimal going forward. Maritech expects to sell its remaining oil and gas producing property interests during 2012.
Maritech gross profit decreased during 2011 compared to 2010 due to the decreased revenues discussed above, although this was largely offset by decreased operating and depletion expenses also as a result of the sales of properties. Although oil and gas property impairments also decreased approximately $48.5 million during 2011 compared to the prior year, this decrease was partially offset by approximately $24.4 million of increased excess decommissioning costs. A large portion of the excess decommissioning costs recorded during 2011 was associated with properties not operated by Maritech. In addition, Maritech recorded approximately $2.5 million of insurance settlement gains during 2010 as a result of settlement and claim proceeds from Hurricane Ike damages. Maritech continues to perform significant decommissioning work on its remaining offshore facilities and platforms, and additional charges for decommissioning costs in excess of estimates may occur in future periods.
43

Despite the decrease in gross profit discussed above, Maritech reported a decreased loss before taxes during 2011 compared to 2010 due to approximately $55.8 million ($57.5 million consolidated) of net gains on the sales of producing properties during the current year period. Partially offsetting this increase in gain on sale was the increase in administrative expenses, primarily due to decreased overhead allocated and billed to joint owners on operated properties, caused by the sales of the properties. In addition, decreased salary, benefit, and employee related expenses resulting from the decrease in administrative staff during the last half of 2011 was largely offset by retention and incentive compensation incurred earlier in the year associated with the sale of Maritech properties. In addition, Maritech administrative expense includes an increase in bad debt expenses, primarily due to a prior year period reversal of bad debt expense.

Corporate Overhead includes corporate general and administrative expense, interest income and expense, and other income and expense. Such expenses and income are generally not allocated to our operating divisions, as they relate to our general corporate activities. However, in connection with the public offering of common units in our Compressco Partners subsidiary, on June 20, 2011, we began allocating and charging Compressco Partners for its share of our corporate administrative costs directly related to Compressco Partners’ activities. Corporate Overhead increased significantly during 2011 compared to 2010, primarily due to increased other expense which resulted from approximately $13.8 million of increased hedge ineffectiveness loss. This increased hedge ineffectiveness loss was due to the April 2011 liquidation of hedge derivative contracts, following the planned sale of a significant portion of Maritech oil and gas producing properties, which resulted in a $14.2 million charge to corporate other expense for hedge ineffectiveness. In addition, other expense increased due to approximately $1.2 million of decreased foreign currency gains and despite a $2.8 million premium that was charged during 2010 in connection with the early repayment of the 2004 Senior Notes. Corporate administrative costs increased due to approximately $1.5 million of increased salaries and other general employee expenses, despite approximately $1.4 million decrease in equity-based compensation. In addition, corporate administrative costs also increased due to approximately $1.1 million of increased insurance and tax expenses. These increases were partially offset by approximately $0.4 million of decreased professional fee expenses.

Consolidated revenues decreased despite increased revenues from our Fluids, Maritech, and Production Testing segments, primarily due to decreases in the revenues of the Offshore Services and Compressco segments. Offshore Services segment revenues decreased by $79.6 million compared to the record levels of 2009, which saw unprecedented activity and demand. Increased onshore oil and gas industry activity during 2010 contributed to the revenue increases by our Production Testing and Fluids Divisions, with the Fluids Division also reflecting increased sales of manufactured products from our new El Dorado, Arkansas, calcium chloride plant. Maritech revenues increased largely because of higher realized oil prices, which include the impact of certain commodity derivative hedges which expired at the end of 2010. Overall gross profit decreased primarily du edue to $72.8 million of decreased profitability from our Offshore Services segment and due to significant impairments and other charges incurred by our Maritech, Offshore Services, and Fluids segments. In addition, the gross profit of our Fluids and Compressco segments were also
44

decreased compared to the prior year. These decreases were partially offset by increased Production Testing gross profit.

Consolidated general and administrative expenses decreased as compared to the prior year due to approximately $3.4 million of decreased bad debt expenses and $0.8 million of decreased insurance expenses during the current year. These decreases were largely offset by approximately $1.8 million of increased employee related costs, including increased salary, benefits, contract labor costs, and other associated employee expenses. In addition, general and administrative expenses during 2010 include $0.2 million of increased professional fees, $0.3 million of increased office expenses, and $1.2 million of increased taxes, investor relations, and other general expenses.

Consolidated interest expense increased primarily due to a decrease in capitalized interest compared to the prior year period following the completion of significant construction projects, including the El Dorado, Arkansas, calcium chloride facility and our corporate headquarters building.

Consolidated other income decreased during 2010 compared to the prior year, primarily due to approximately $7.4 million of decreased gains on sales of assets, $3.8 million of decreased legal settlement gains, $1.2 million of decreased foreign currency gains, and due to the expensing of a $2.8 million prepayment premium on the repayment of the 2004 Senior Notes. These decreases were partially offset by $9.2 million of increased earnings in an unconsolidated joint venture, primarily due to a $6.8 million charge for an impairment of our Fluids Division European joint venture investment during 2009. In addition, we recorded $1.6 million of decreased hedge ineffectiveness losses compared to the prior year.

We recorded a consolidated income tax benefit of $30.5 million during 2010 due to our net loss for the period. This compares to a consolidated tax provision of $36.6 million during 2009.

The increase in Fluids Division revenues as compared to the prior year was primarily due to $44.0 million of increased product sales revenues. This increase in product sales revenues was partially attributed to increased revenues from sales of liquid calcium chloride produced from our El Dorado, Arkansas, calcium chloride plant, which began production during the fourth quarter of 2009. Product sales revenues also increased due to increased domestic sales volumes of clear brine fluids (CBFs), particularly during the fourth quarter of 2010. Domestic product sales revenues also benefitted from increased pricing compared to the prior year and due to a significant sale of bromide products during the first quarter of 2010. International product sales revenues also increased, due to improved oil and gas activity levels in certain of the foreign markets w ewe serve and due to increased product sales from our European calcium chloride operations. The increase in domestic product sales revenues during 2010 occurred despite the decreased activity and pricing on product sales to domestic deepwater operators as a result of the deepwater drilling moratorium, which was in effect during a portion of the year. Although this moratorium was lifted in October 2010, delays due to permitting and increased regulatory requirements have continued to slow the return of improved demand in the deepwater Gulf of Mexico. However, CBF sales volumes increased during the fourth quarter of 2010, and this trend may indicate that activity levels are increasing going forward. In addition to increased product sales

revenues, service revenues increased by approximately $6.9 million due to increased domestic frac water and filtration service activities.

Despite the increased revenues, gross profit decreased compared to the prior year primarily due to the significant losses from our domestic calcium chloride manufacturing operations. These losses were primarily due to the $7.2 million impairment of the Division’s Lake Charles, Louisiana, calcium chloride plant. Due to the current market pricing for calcium chloride and the uncertain supply of raw materials needed to operate the plant on economic terms, the expected operating cash flows of the plant arewere insufficient to cover the plant’s carrying value, resulting in the impairment. In addition, start-upstart up costs and continuing production inefficiencies have negatively affected the profitability of our El Dorado, Arkansas, calcium chloride plant. We continue to take steps to improve the operational efficiency of this plant; however, there is still considerable effort required, and significant improvement in plant performance is not expected until mid 2011.plant. Partially offsetting the significantly decreased profitability of our domestic calcium chloride manufacturing operations, gross profit on CBF sales and completion services increased approximately $5.4 million, due to the increased activity levels during the current year. In addition, gross profit from the Division’s European calcium chloride manufacturing operations also increased.

Income before taxes decreased compared to the prior year, primarily due to the decreased gross profit discussed above and due to an increase in general and administrative expense, primarily due to increased employee-related costs. This decrease in profitability was partially offset by a significant decrease in other expense as compared to the prior year when we recorded a $6.5 million charge for the impairment of the Division’s investment in a European unconsolidated joint venture. Partially offsetting this decrease in other expense, other income decreased as a result of decreased foreign currency gains on the Division’s international operations.

The decrease in revenues for the Offshore Services segment was due to decreased activity compared to the record levels experienced in the prior year period. The decreased activity resulted in reduced utilization of much of the segment’s fleet as compared to the prior year period, without taking into effect the addition of a leased dive support vessel beginning in June 2009. In addition to the decreased activity for certain of the segment’s operations, overall pricing levels were lower during 2010 compared to the prior year. During 2010, the BOEMRE issued NTL 2010-G05, the “Idle Iron Guidance” regulations, which require that permanent plugs be set in nearly 3,500 nonproducing wells in the U.S. Gulf of Mexico. In addition, the new regulation requires approximately 650 oil and gas production platforms to be dismantled if they are not being used. We anticipate that these new requirements will increase, perhaps significantly, the future demand for well abandonment and decommissioning services to be performed by our Offshore Services segment. In addition, we continue to capitalize on the remaining demand for well abandonment and decommissioning services for the remaining offshore properties that were damaged or destroyed by hurricanes. Still, we anticipate that levels of Offshore Services segment activity in 2011 will again be lower than the record activity levels we experienced during most of 2009. A total of $62.5 million of the segment’s revenues during 2010 were performed for Maritech, compared with $45.6 million during the prior year. These intersegment revenues are eliminated in the consolidated statements of operations.

The decrease in gross profit was primarily due to the decreased activity and pricing, but also included the impact of decreased utilization and efficiencies compared to the prior year period. In addition, during the fourth quarter of 2010, the Offshore Services segment recorded an impairment of $15.3 million to the net carrying value of the Epic Diver, a dive support vessel owned by our Epic Diving & Marine Services subsidiary. We determined that the vessel is no longer strategic to the segment’s plan to serve its markets going forward. In addition, the segment recorded additional impairments of approximately $2.4 million during 2010, associated with other non-strategic assets. As a result of the NTL 2010-G05 regulations discussed above, we anticipate that activity and profitability levels of the Offshore Services segment will increase c ompared to 2010. However, we expect 2011 profitability to be lower than the record high profitability levels of 2009, due to the expected decrease in utilization rates and pricing.

The decrease in income before taxes was primarily due to the decreased gross profit discussed above. Increased general and administrative expenses include the impact of increased salaries and personnel-related costs compared to the prior year. Partially offsetting these decreases, other expense during 2009 included a charge for a $2.0 million legal settlement.

Approximately $41.1 million of Maritech revenues was due to increased realized commodity prices during 2010 compared to the prior year. Maritech has hedged a portion of its expected future oil production levels by entering into commodity derivative hedge contracts, with certain contracts extending through 2011, although contracts having a positive impact compared to market prices expired at the end of 2010. Including the impact of its commodity derivative hedge contracts, Maritech reflected average realized oil and natural gas prices during 2010 of $96.63/barrel and $8.47/MMBtu, respectively, each of which were significantly higher than market prices of oil and natural gas during the period. Much of the favorable hedged oil pricing impact was as a result of 2010 oil swaps that were liquidated during 2009. Partially offsetting the increased realize d prices, overall production volumes decreased during the current year period, resulting in $18.1 million of decreased revenues. This decrease was attributed to natural gas production interruptions and normal production declines during the period. A portion of Maritech’s Main Pass area production is currently shut-in due to third-party pipeline issues and the lack of available transportation for production. Although total oil production increased compared to the prior year period, Maritech’s interest in the East Cameron 328 field will continue to have a portion of its production shut-in until Maritech completes the redrilling of certain wells from a newly installed platform to replace the platform that was toppled during Hurricane Ike in 2008. Recent successful development efforts at Maritech’s Timbalier Bay field are expected to result in increased production going forward. However, since late 2008, as a result of our efforts to conserve capital and decrease our investment in Maritech, we have significantly reduced overall acquisition and development activities, and the level of such activity is expected to continue to be decreased going forward. In February 2011, Maritech sold a portion of its oil and gas properties, which will also result in decreased revenues going forward. In addition, Maritech reported $0.1 million of decreased processing revenue during 2010.

Despite the increased revenues, Maritech’s gross profit for 2010 decreased significantly compared to the prior year due to several factors. During 2009, Maritech recorded $42.2 million of additional credits to operating expense for the collection of insurance settlement proceeds, primarily from the $40 million insurance litigation settlement in December 2009 regarding certain claims associated with damage from
47

Hurricanes Katrina and Rita. In addition, partly due to the issuance by the BOEMRE of NTL 2010-G05 “Idle Iron Guidance” regulations in the U.S. Gulf of Mexico, Maritech significantly adjusted its decommissioning liabilities as of December 31, 2010. Largely as a result of these adjustments, as well as a result of the cost of significant abandonment and decommissioning work performed during the year, Maritech recorded approximately $30.2 million of increased excess decommissioning expense associated with work performed or to be performed on nonproductive oil and gas properties. In addition, adjustments to decommissioning liabilities associated with productive properties were capitalized to oil and gas properties and, along with the decreased fair value of certain oil and gas properties, contributed significantly to Maritech recording approximately $52.4 million of increased oil and gas property impairments during 2010 compared to the prior year. Partially offsetting these increased operating expenses were approximately $3.1 million of decreased insurance expense and $5.9 million of decreased repair expense, primarily due to the amount of repairs performed during 2009 associated with Hurricane Ike.

Maritech’s pretax profitability decreased during 2010 compared to 2009, primarily due to the significant decrease in gross profit discussed above. In addition, Maritech other income decreased due to gains that were recorded during 2009 on sales of oil and gas properties. Partially offsetting these decreases, Maritech general and administrative expenses decreased, primarily due to decreased bad debt expense.

The increase in revenues for the Production Testing segment was primarily due to a $16.9 million increase in domestic operations, approximately $10.0 million of which was recorded during the fourth quarter of 2010. This increase reflects the increase in domestic drilling activity, which we anticipate will continue in 2011.activity. In addition, international operations generated $9.4 million of increased revenues. Approximately $6.3 million of this increase was associated with a South American technical management contract. Increased international revenues were reported during 2010 due to increases in Eastern Hemisphere and Brazil, and were partially offset by decreased activity and revenues in Mexico, where customer budgetary issues, security disruptions, and regional flooding during the year have negatively affected activity levels.

The increase in gross profit was due to approximately $6.7 million of increased domestic gross profit, which more than offset the approximately $1.4 million decrease in international gross profit. Domestic profitability increased due to the higher activity levels and improved operating efficiencies. While international production testing operations have historically generated higher operating margins than domestic operations, decreased activity and operating interruptions in Mexico have hampered international profitability.

Despite the increase in gross profit, income before taxes decreased primarily due to a $5.8 million gain from a legal settlement which was recorded in the prior year. This decrease in other income plus increased administrative costs was partially offset by the increased gross profit during the current year.

The decrease in Compressco revenues was due to $5.6 million of decreased U.S. compression service revenues, primarily reflecting the reduced U.S. demand for wellhead compression services during 2010. We believe the reduced demand was primarily due to continuing lower natural gas prices compared to
47

prices during previous years, as well as due to the impact of increased competition. Compressco’s domestic activity levels have begun to increase during the pastlast three quarters of 2010, and fourth quarter of 2010 revenue levels were increased compared to the prior year period. Over the past year, many domestic oil and gas operators, including certain Compressco customers, have responded to the lower gas prices by reducing operating expenses. In addition, international service revenues also decreased by $3.1 million, primarily due to decreased activity in M exico. Going forward, we anticipate that Compressco’s international revenues will continue to be negatively affected by conditions in Mexico, where customer budgetary issues and security disruptions have negatively impacted activity levels during 2010.Mexico. Revenues from sales of compressor units and parts during 2010 decreased $0.8 million compared to the prior year. Compressco has reduced the fabrication of new compressor units until demand for its production enhancement services increases and inventories of available units are reduced.

The decrease in gross profit was due to decreased demand domestically for Compressco’s products and services, as well as due to the above described decreased activity in Mexico. Domestic profitability during 2010 was also affected by decreased pricing and certain non-recurring operating charges during the year. Gross profit as a percentage of revenues also decreased due to the decreased activity, despite Compressco’s efforts to improve operating efficiencies.

The decrease in income before taxes was primarily due to the decrease in gross profit and, to a lesser extent, from increased administrative expenses, which were primarily due to increased salary and personnel-related expenses.

The decrease in revenues for the Offshore Services segment was due to decreased activity compared to the record levels experienced in the prior year period. The decreased activity resulted in reduced utilization of much of the segment’s fleet as compared to the prior year period, without taking into effect the addition of a leased dive support vessel beginning in June 2009. In addition to the decreased activity for certain of the segment’s operations, overall pricing levels were lower during 2010 compared to the prior year. During 2010, the BOEMRE issued NTL 2010-G05, the “Idle Iron Guidance” regulations, which require that wells located in Federal waters must be permanently plugged within three years of becoming uneconomic to operate and that platforms and other infrastructure must be removed within five years of becoming uneconomic to operate. We anticipate that these new requirements will increase the future demand for well abandonment and decommissioning services to be performed by our Offshore Services segment. In addition, we continue to capitalize on the remaining demand for well abandonment and decommissioning services for the remaining offshore properties that were damaged or destroyed by hurricanes. A total of $62.5 million of the segment’s revenues during 2010 were performed for Maritech, compared with $45.6 million during the prior year. These intersegment revenues are eliminated in the consolidated statements of operations.

The decrease in gross profit was primarily due to the decreased activity and pricing, but also included the impact of decreased utilization and efficiencies compared to the prior year period. In addition, during the fourth quarter of 2010, the Offshore Services segment recorded an impairment of $15.3 million to the net carrying value of the Epic Diver, a dive support vessel owned by our Epic Diving & Marine Services subsidiary. We determined that the vessel was no longer strategic to the segment’s plan to serve its markets
48

going forward. In addition, the segment recorded additional impairments of approximately $2.4 million during 2010, associated with other non-strategic assets.

The decrease in income before taxes was primarily due to the decreased gross profit discussed above. Increased general and administrative expenses include the impact of increased salaries and personnel-related costs compared to the prior year. Partially offsetting these decreases, other expense during 2009 included a charge for a $2.0 million legal settlement.

Much of the favorable hedged oil pricing impact was as a result of 2010 oil swaps that were liquidated during 2009. Partially offsetting the increased realized prices, overall production volumes decreased during the current year period, resulting in $18.1 million of decreased revenues. This decrease was attributed to natural gas production interruptions and normal production declines during the period. A portion of Maritech’s Main Pass area production was shut-in due to third-party pipeline issues and the lack of available transportation for production. Although total oil production increased compared to the prior year period, Maritech’s interest in the East Cameron 328 field will continue to have a portion of its production shut-in until Maritech completes the redrilling of certain wells from a newly installed platform to replace the platform that was toppled during Hurricane Ike in 2008. Successful development efforts at Maritech’s Timbalier Bay field are expected to result in increased production going forward. However, since late 2008, as a result of our efforts to conserve capital and decrease our investment in Maritech, we have significantly reduced overall acquisition and development activities, and the level of such activity is expected to continue to be decreased going forward. In February 2011, Maritech sold a portion of its oil and gas properties, which will also result in decreased revenues going forward. In addition, Maritech reported $0.1 million of decreased processing revenue during 2010.

Despite the increased revenues, Maritech’s gross profit for 2010 decreased significantly compared to the prior year due to several factors. During 2009, Maritech recorded $42.2 million of additional credits to operating expense for the collection of insurance settlement proceeds, primarily from the $40 million insurance litigation settlement in December 2009 regarding certain claims associated with damage from Hurricanes Katrina and Rita. In addition, partly due to the issuance by the BOEMRE of NTL 2010-G05 “Idle Iron Guidance” regulations in the U.S. Gulf of Mexico, Maritech significantly adjusted its decommissioning liabilities as of December 31, 2010. Largely as a result of these adjustments, as well as a result of the cost of significant abandonment and decommissioning work performed during 2010, Maritech recorded approximately $30.2 million of increased excess decommissioning expense associated with work performed or to be performed on nonproductive oil and gas properties. In addition, adjustments to decommissioning liabilities associated with productive properties were capitalized to oil and gas properties and, along with the decreased fair value of certain oil and gas properties, contributed significantly to Maritech recording approximately $52.4 million of increased oil and gas property impairments during 2010 compared to the prior

year. Partially offsetting these increased operating expenses were approximately $3.1 million of decreased insurance expense and $5.9 million of decreased repair expense, primarily due to the amount of repairs performed during 2009 associated with Hurricane Ike.

Maritech’s pretax profitability decreased during 2010 compared to 2009, primarily due to the significant decrease in gross profit discussed above. In addition, Maritech other income decreased due to gains that were recorded during 2009 on sales of oil and gas properties. Partially offsetting these decreases, Maritech general and administrative expenses decreased, primarily due to decreased bad debt expense.

Corporate Overhead includes corporate general and administrative expense, interest income and expense, and other income and expense. Such expenses and income are not allocated to our operating divisions, as they relate to our general corporate activities. Corporate Overhead increased during 2010 compared to the prior year, as decreased general and administrative expenses were offset by increased interest expense and other expense. Corporate general and administrative costs decreased primarily due to approximately $4.4 million of decreased salaries and employee-related expenses, which was mainly due to decreased incentive compensation. In addition, general and administrative expenses decreased due to $0.4
49

million of decreased office expenses, $0.4 million of decreased insurance and taxes expenses, $0.1 million of decreased professional fee expenses, and approximately $0.4 million of decreased general expenses. These decreases were partially offset by approximately $0.2 million of increased investor relations expenses. Largely offsetting this decrease, corporate interest expense increased due to a decrease in the amount of interest capitalized on construction projects during the period, particularly following the completion of the construction of the El Dorado, Arkansas, calcium chloride facility. In addition, other expense increased, despite a $1.6 million decrease in hedge ineffectiveness losses, due to the charge for approximately $2.8 million in prepayment premium on the repayment of the 2004 Senior Notes.

Consolidated revenues decreased despite a significant increase in our Offshore Services segment revenues. This was due to decreased revenues by each of the other reporting segments, which reflected the impact of the general decline in oil and gas industry activity during 2009. This decrease was primarily due to the global economic environment and specifically due to lower oil and natural gas commodity prices during 2009 compared to 2008. Offshore Services revenues increased by $47.4 million due to increased demand for diving, platform decommissioning, cutting, and abandonment services during 2009, following the damage to offshore platforms from hurricanes in the Gulf of Mexico in prior years and due to the risk of damage from future storms. This increase was more than offset by significantly decreased revenue from our Fluids Division, which experi enced decreased demand for its products, primarily due to decreased oil and gas completion activity. In addition, our Production Testing, Maritech, and Compressco segments also reported decreased revenues, generally due to decreased demand resulting from lower oil and gas commodity pricing. Despite these decreases, overall gross profit increased during 2009 compared to 2008, primarily due to the unprecedented favorable performance of our Offshore Services segment, a favorable litigation settlement, and due to significant impairments to oil and gas properties during 2008.

During the fourth quarter of 2008, changes to the global economic environment resulting in uncertain capital markets and reductions in global economic activity had a severe impact on the estimated fair value of each of our reporting units as of December 31, 2008. As part of our annual test of goodwill impairment, we determined that an impairment of the goodwill of our Fluids and Offshore Services reporting units was necessary. Accordingly, we recorded goodwill impairment charges for these segments.

Consolidated general and administrative expenses decreased primarily due to approximately $2.2 million of decreased salary, benefits, contract labor costs, and other associated employee expenses, primarily due to overall personnel cost reduction efforts. This decrease was despite increased incentive bonus and equity compensation expenses. General and administrative expenses were also decreased due to approximately $2.1 million of decreased office expense, primarily from decreased office rent following the first
50

quarter 2009 relocation to our new corporate headquarters building, approximately $0.8 million of decreased professional fees, and approximately $0.6 million of decreased marketing, investor relations, and other general expenses. These decreases were partially offset by approximately $1.3 million of increased insurance and property tax expenses and approximately $0.3 million of increased bad debt expenses.

Consolidated other income decreased primarily due to the change in hedge ineffectiveness, as we recognized approximately $1.7 million of hedge ineffectiveness losses during 2009 compared to $8.6 million of hedge ineffectiveness gains during the prior year. In addition, earnings from unconsolidated joint ventures decreased $5.7 million, primarily due to an impairment charge of approximately $6.6 million during 2009 associated with the write down of our unconsolidated European joint venture investment. Partially offsetting these decreases, we recorded $4.6 million of increased net legal settlement income, $4.0 million of increased gains on sales of assets, and $0.4 million of increased foreign currency gains during 2009.

Consolidated net interest expense decreased, despite increased borrowings of long-term debt during much of the year. The increased borrowings were used to fund our 2009 capital expenditure and working capital requirements. The decrease in interest expense was primarily due to $3.6 million of increased capitalized interest primarily associated with our Arkansas calcium chloride plant and corporate headquarters construction projects. The corporate headquarters building was completed during the first quarter of 2009, and our calcium chloride facility in El Dorado, Arkansas, began initial production during the fourth quarter of 2009. Accordingly, despite a decrease in the balance of long-term debt outstanding as of December 31, 2009, our net interest expense is expected to increase beginning in 2010 since the amount of interest capitalized will be red uced.

Consolidated provision for income taxes increased primarily due to increased earnings.

The decrease in Fluids Division revenue was primarily due to a $59.6 million decrease in product sales revenues, primarily due to decreased sales volumes of completion fluids as a result of the overall decreased demand for the Division’s brine products. This decrease reflects the overall decreased industry spending as reflected in the U.S. and international rig counts during 2009 compared to 2008 and the trend of many operators during 2009 to defer completion operations on drilled oil and gas wells. In addition, the decreased product sales revenues were due to decreased sales volumes of the Division’s manufactured chemicals products, primarily due to the impact of decreased economic conditions which have affected the level of activity of the Division’s oil and gas industry customers. The Division also reflected $8.1 million of de creased service revenues, primarily due to decreased U.S. onshore oil and gas activity. During the fourth quarter of 2009, the Division began initial production of liquid calcium chloride from its El Dorado, Arkansas, plant facility. The plant also began initial production of dry calcium chloride in early 2010.

The decrease in Fluids Division gross profit was primarily due to the decreased sales volumes discussed above, particularly for U.S. completion fluids products. In addition, the Fluids Division recorded approximately $1.4 million of impairments of long-lived assets during 2009. Gross profit as a percentage of

revenue increased, however, due to increased international margins, particularly by the Division’s European calcium chloride operation. As discussed above, the Division’s new El Dorado, Arkansas, calcium chloride plant facility began initial production during the fourth quarter of 2009.

The increase in Fluids Division income before taxes was primarily due to a non-recurring $23.9 million charge for the impairment of goodwill recorded during the fourth quarter of 2008. This increase was partially offset by the $8.9 million decrease in gross profit discussed above and a $6.5 million charge during 2009 associated with the impairment of the Division’s investment in a European unconsolidated joint venture. The joint venture ceased operation of the calcium chloride manufacturing plant following our joint venture partner’s announced closure of its adjacent plant facility which supplies the joint venture’s plant with feedstock raw material. These decreases in earnings were partially offset by approximately $6.2 million of decreased administrative expenses and approximately $0.9 million of increased other income, which w as primarily due to a $1.4 million charge for a legal settlement in the prior year period.

The increase in Offshore Services revenues was due to increased utilization, particularly by the segment’s diving, abandonment, heavy lift, and cutting services businesses, which enjoyed unprecedented high demand following the 2005 and 2008 hurricanes. Beginning in June 2009, the segment increased its service fleet through the leasing of a specialized dive support vessel which was utilized for contracted hurricane recovery work during the remainder of the year. In addition, many offshore oil and gas operators, including Maritech, have accelerated their efforts to abandon and decommission offshore platform facilities in response to the risks from future storms and the significantly increased windstorm insurance cost for offshore properties. Many operators have discontinued or reduced their windstorm insurance coverage until premium costs decr ease or become justifiable and are seeking to maximize their abandonment and decommissioning activity in order to decrease their risk of future damage.

The increase in gross profit was primarily due to the increased gross profit of the segment’s heavy lift, diving, and cutting services businesses, which generated significant efficiencies from increased utilization during 2009. These efficiencies were partially due to improved weather conditions during 2009, as the segment incurred significant downtime during the third quarter of 2008 due to Hurricanes Gustav and Ike. The hurricane season from June through November can generate significant downtime in certain years. In addition, heavy seas, winds, and winter squalls tend to disrupt activities and, therefore, reduce demand for our services in the first and fourth quarters. Also during 2008 the Offshore Services segment recorded an $8.7 million impairment of certain long-lived assets. In addition, during 2009 the segment consolidated certain o ffice and administrative functions, reduced crews, and sold or temporarily idled selected inland water equipment in order to increase efficiencies for certain of its operations.

52

Offshore Services segment income before taxes increased due to the increase in gross profit described above and $2.5 million of decreased administrative expenses, partially offset by approximately $1.8 million of increased other expense, primarily due to a legal settlement during the third quarter of 2009. In addition, the Offshore Services segment recorded a charge to earnings of $23.2 million for a goodwill impairment during the fourth quarter of 2008.

Maritech’s revenues decreased during 2009 compared to the prior year due to decreased pricing and production volumes. Decreased realized commodity prices resulted in $17.7 million of decreased revenues, as during 2009 Maritech reflected average realized oil and natural gas prices of $65.13/barrel and $8.41/MMBtu, respectively, each of which was lower than 2008 levels. Maritech has hedged a portion of its expected future production levels by entering into derivative hedge contracts. The average realized prices above include the impact of these hedge contracts during 2009, which significantly reduced the impact of decreased prices during the year. In addition to decreased pricing, decreased Maritech production volumes resulted in decreased revenues of approximately $15.3 million primarily due to one of Maritech’s key oil producing fields , the East Cameron 328 field, being shut-in for most of the year. The decreased production from normal production declines and the shut-in properties more than offset newly added production during the period from wells drilled in 2008 and 2009. The level of Maritech’s drilling and development activity has decreased during 2009 as a result of our efforts to conserve capital. Partially offsetting the revenue decreases associated with decreased pricing and production volumes, Maritech reported $1.5 million of increased processing revenue during the current year period.
The increase in gross profit was primarily due to the $44.7 million of increased insurance related gains, primarily from the $40 million settlement of our insurance litigation regarding claims associated with damage from Hurricanes Katrina and Rita. The proceeds from this settlement were received during the fourth quarter of 2009. In addition, Maritech recorded oil and gas property impairments of $11.4 million during 2009, compared to $42.6 million during 2008. Also, Maritech recorded $13.8 million of decreased operating expenses and depreciation, depletion, and amortization during 2009 compared to the prior year. This decrease was primarily due to decreased production volumes and reduced insurance premium costs, following Maritech’s decision to self insure from windstorm damage risk during the last half of the year. Maritech also recorded $ 9.1 million of dry hole costs during 2008. Partially offsetting these expense decreases, Maritech recorded $16.7 million of increased excess decommissioning costs incurred during 2009.
The increase in Maritech income before taxes compared to the prior year was due to the increase in gross profit discussed above, approximately $2.9 million of increased gains on sales of properties recorded, and approximately $0.7 million of decreased administrative costs, partially offset by approximately $0.3 million of decreased other income during 2009.

Production Testing revenues decreased due to the decrease in U.S. operations, primarily from reduced drilling activity as reflected by the U.S. rig count. The decreased demand also resulted in decreased day rates for our services. The Division’s Production Testing segment is particularly affected by the activities of its U.S. customers, many of which have been significantly affected by the current economic climate. This decrease was partially offset by increased international revenues, primarily in Mexico and Brazil.

Production Testing gross profit decreased primarily due to an approximately $24.7 million decrease in domestic gross profit due to the weaker demand, lower day rates, and decreased activity in the U.S. In addition, gross profit from international production testing activities also decreased by approximately $0.3 million.

Production Testing income before taxes decreased due to the $25.0 million decrease in gross profit discussed above, which was partially offset by approximately $7.1 million of increased other income, primarily due to a $5.6 million legal settlement gain, $0.5 million of increased gains on sales of assets, and $1.0 million of increased other income, primarily from increased earnings from an unconsolidated joint venture.

Compressco revenues during 2009 decreased, reflecting the decreased U.S. demand during most of 2009 compared to the prior year. Lower natural gas prices and general industry economic conditions resulted in decreased demand compared to 2008 for wellhead compression services, as reflected in Compressco’s reduced utilization of its GasJack® compressor fleet. Beginning in early 2009, Compressco reduced the fabrication of new compressor units until demand for its production enhancement services increases and inventories of available units are reduced. However, Compressco continues to seek new niche opportunities to expand its operations, including additional opportunities in international markets.
54

Compressco gross profit decreased primarily due to decreased activity and due to unabsorbed fabrication overhead as a result of the decreased production of new compressor units along with other increased operating expenses for Compressco’s U.S. operations.

Income before taxes for Compressco decreased primarily due to the $7.8 million of decreased gross profit discussed above, partially offset by decreased administrative costs and increased other income.

Corporate Overhead includes corporate general and administrative expense, interest income and expense, and other income and expense. Such expenses and income are not allocated to our operating divisions, as they relate to our general corporate activities. Corporate administrative costs increased primarily due to approximately $6.9 million of increased salary and employee expenses. Although Corporate employee salary expenses decreased due to cost reduction efforts, these decreases were more than offset by increases in company-wide incentive bonus and equity compensation expense. In addition, Corporate administrative expenses increased due to approximately $1.0 million of increased insurance, taxes, and other general expenses. These administrative cost increases were partially offset by $1.0 million of decreased professional services and investor re lations expense and $0.9 million of decreased office expenses, primarily from decreased office rent following the first quarter 2009 relocation to our new corporate headquarters building. In addition to increased administrative expenses, other expense increased due to $1.7 million of hedge ineffectiveness losses included in other expense during 2009 compared to $8.6 million of hedge ineffectiveness gains which were included in other income during 2008. In addition, Corporate Overhead expense increased due to $0.6 million of increased depreciation expense, primarily due to our new corporate headquarters building. Partially offsetting these increases, Corporate interest expense decreased during 2009 primarily due to an increase in the amount of interest capitalized on construction projects during the period.

Liquidity and Capital Resources

During the past year we have continued to conserve capital, improveended December 31, 2011, our liquidity position was significantly affected by several transactions. The sales of substantially all of Maritech’s oil and maintain a strong financial position. During the fourth quartergas producing properties generated total cash, net of 2010, we sold $90 millionprice adjustments, of Series 2010 Senior Notes, using the proceeds from the offering to help retire $91.8 million of Series 2004 Senior Notes which were scheduled to mature in September 2011.approximately $181.4 million. In addition, we amendedthe sales of oil and gas properties allow us to prioritize our bank credit facility to extend its scheduled maturity to October 2015, which will provide a source of capital for the next five years. We continue to fund our existingfuture capital expenditure needs however, fromtoward our operating cash flows. Our operating cash flowscore oil and gas services businesses, as Maritech exploitation and development activity historically represented a significant use of our capital resources. Maritech has retained approximately $132.8 million of decommissioning liabilities as of December 31, 2011, associated primarily with non-productive offshore facility and production platform assets, and we anticipate extinguishing the significant majority of this work during 2010 were significantly less than 2009, primarily due to2012. In July 2011, we increased the decreased profitability and cash flows fromheavy lift capacity of our Offshore Services segment with the purchase of the TETRA Hedron, a 1,600-metric ton heavy lift vessel. The addition of this vessel, which enjoyed unprecedented activity levels during the prior year. Also, o perating cash flows during 2010 have been negatively affected by the current uncertain regulatory environment following the recent eventswas purchased for approximately $62.8 million, should allow us to serve Offshore Services customers with heavier structures in the Gulf of Mexico, low natural gas prices, andMexico. Also during June 2011, our subsidiary, Compressco Partners, finalized its initial public Offering, which generated approximately $42.2 million of Offering proceeds, net of offering costs. Approximately $32.2 million of these Offering proceeds were used to repay to us certain intercompany note balances. Following the effects of the continuing economic recovery. Still, the demand for the products and services of manyOffering, in which we retained an approximate 83% ownership, we continue to consolidate Compressco Partners as part of our businesses was improving during 2010 comparedCompressco segment in our consolidated financial statements; however, separate cash balances are now maintained by Compressco Partners to the prior year, and this bodessatisfy its operating requirements as well for additional growth in 2011. The capital expenditure plans for many of our businesses are also increasing from 2010 levels, and we anticipate these expenditures will again be funded primarily from operating cash flows. However, dueas to a desirefund quarterly distributions pursuant to conserve and reallocate capital, we have begun to decrease our investment in Maritech by suspending our search for oil and gas property acquisitions and decreasing our development activities. In addition, we are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and we are reviewing opportunities to sell Maritech oil and gas property packages to industry participants and other third parties.partnership agreement. As part of this overall effort, in late February 2011, Maritech sold a group of properties that accounted for 11.4% of its proved reserves as of December 31, 2010. Our capital conservation efforts are expected to position us so that2011, we may continue to seek acquisitionhad consolidated cash of approximately $204.4 million, approximately $17.5 million of which is held by Compressco Partners and growth opportunities that meet certain criteria,is unavailable for our general purposes.

Additional capital resources are also available to us in the form of existing businesses in niche marketsadditional debt borrowings, equity issuances, or through suitable acquisitions.other sources of capital. This liquidity and access to capital resources allows us to consider funding additional capital expenditure projects as well as potential acquisition transactions, as opportunities become available.

Operating Activities

Cash flows generated by operating activities totaled approximately $43.8 million during 2011 compared to $153.3 million during 2010, compared to $272.3 million during 2009, a decrease of 43.7%71.4%. Approximately $47.8 million of current periodthe 2010 operating cash flows were generated from insurance settlements and claims proceeds from a portion of Maritech’s insurance coverage related to damages suffered from Hurricane Ike during 2008. Operating cash flows from insurance settlement collections were similarly significant during 2009. Prior period operating cash flows include $23.1 million from the liquidation of certain oil swap derivative contracts. However, theThe remaining decrease in operating cash flows compared to 2010 was due to decreased earnings, excluding the gains on sales of assets and depreciation expense, during 2010 primarily reflects2011. During the decreasedpast three year period ended December 31, 2011, our operating cash flows of our Offshore Services segment, which enjoyed unprecedented demand for its products and services during 2009.

Operating cash flows were also reduced during 2010 as a result of the regulatory uncertainty that followed the April 2010 Macondo oil spill in the U.S. Gulf of Mexico. Future operating cash flows for many of our businesses will also be largely dependent upon the level of oil and gas industry activity, particularly in the U.S. Gulf of Mexico region. As a result of the Macondo oil spill, regulatory requirements for offshore operators, particularly deepwater operators, have increased. We estimate that the combined impact of the recent U.S. government imposed deepwater drilling moratorium and related regulatory issues resulted in the reduction of our consolidated revenues by approximately $22 to $25 million during 2010, compared to the level of revenues we would have expected ha d the recent events in the Gulf of Mexico not occurred. This decrease was experienced primarily by our Fluids Division, although our Offshore Services segment was also affected. Although the deepwater drilling moratorium was lifted in October 2010, the impact of regulatory uncertainty is expected to continue to negatively affect the cost and timing of offshore activities in the future, perhaps significantly. Many within the oil and gas industry are expecting further increases in regulatory requirements for all U.S. offshore drilling and production operations, particularly for deepwater projects. Operators are currently experiencing delays in permitting for deepwater as well as shallow water offshore projects. A portion of our revenues will continue to be impactedbeen affected by the current regulatory environment. Following the Macondo spillsignificant and the announcementincreasing amount of the drilling moratorium, the U.S. Gulf of Mexicodecommissioning work performed by Maritech on its offshore rig count dropped significantly, and while this offshore rig count has improved recently, it is stil l below pre-Macondo spill levels. For certain of our businesses, increased government regulations could affect us positively. However, to the extent more stringent government regulations affecting deepwater and shallow water drilling are enacted, our future revenues and operating cash flows could be negatively affected overall.

Perhaps the most significant impact affecting our operations from the newly enacted regulations following the Macondo oil spill is the new NTL 2010-G05 “Idle Iron Guidance” regulation which requires that permanent plugs be set in nearly 3,500 nonproducing wells and that approximately 650 oil and gas production platforms be dismantled if they are no longer being used. These “Idle Iron Guidance” requirements are expected to increase, possibly significantly,facilities and platforms.

During the future demand for thethree year period ended December 31, 2011, Maritech expended approximately $277.3 million on well abandonment and decommissioning serviceswork performed. As of our Offshore Services segment. Also significantly affected is our Maritech subsidiary, asDecember 31, 2011, and following the new regulatory requirement is one factor resulting in Maritech significantly increasing its estimatesale of the decommissioning liabilities for the plugging, abandonment, and decommissioningsubstantially all of itsMaritech’s producing oil and gas prope rties as of December 31, 2010. Our future operating cash flow will be affected byproperties, the actual timing and amount of these decommissioning expenditures.

Our Offshore Services segment is expected to be extinguished in future years, as reserves are depleted.perform a majority of this work. The amount and timing of thesethe cash outflows associated with all of Maritech’s remaining decommissioning liabilities are estimated based on expected costs as well as on the timing of future oil and gas production and the resulting depletion of Maritech’s oil and gas reserves.project scheduling. Such estimates are imprecise and subject to change due to changing cost estimates, further changes to BOEMREBSEE requirements, commodity prices, revisions of r eserve estimates, and other factors. In addition to the impact from regulatory changes, Maritech’s increased decommissioning liabilities also reflect the decision to limit future development activity. This decision results in the acceleration of the estimated timing of when abandonment and decommissioning activities on certain properties will be performed.

Maritech’s estimated decommissioning liabilities are net of amounts allocable to joint interest owners

and any contractual amounts to be paid by the previous owners of the properties. In some cases, the previous owners of the properties that were acquired by Maritech are contractually obligated to pay Maritech a fixed amount for the future well abandonment and decommissioning work on these properties as the work is performed, which partially offsets Maritech’s future expenditures. Maritech’s estimated decommissioning liabilities are net of amounts allocable to joint interest owners and any contractual amounts to be paid by the previous owners of the properties. As of December 31, 2010,2011, Maritech’s total undiscounted decommissioning obligation is approximately $321.7$139.8 million and consists of Maritech’s total liability of $285.8$132.8 million plus approximately $35.9$7.0 million of such contractual reimbursement arrangements with the previous owners. An additional $13.6 million of such contractual reimbursement arrangements as of December 31, 2011, is classified as receivable assets related to amounts waiting to be invoiced and collected.

Offshore well abandonment and decommissioning operations in the U.S. Gulf of Mexico are governed by NTL 2010-G05 “Idle Iron Guidance” regulation, which requires that wells must be plugged within three years of becoming uneconomic to operate. Previously, the requirement was to perform this work after the last well in a field was depleted. In October 2011, the BOEMRE’s responsibilities were divided between the BOEM and the BSEE, which will oversee the provisions of the “Idle Iron Guidance.” These “Idle Iron Guidance” requirements are expected to increase the future demand for the abandonment and decommissioning services of our Offshore Services segment.

While the timing and strength of the currentoverall global economic recoveryeconomy continues to be difficult to predict, industry rig count and other data indicates that domestic oil and gas industry spending is increasing, spurred by the current strong pricing for crude oil and the recent trends for onshore shale gas exploitation. Still, domestic oil and gas operators’ activities and spending levels are significantly below early 2008 levels. Demand for a large portion of our products and services is driven by oil and gas drilling and production activity, which is affected by oil and natural gas commodity pricing. In particular, our Production Testing Compressco, and Fluids segments reported increased onshore domestic activity levels during the last half of2011 compared to 2010. We are anticipating similar increases incontinued strong revenues and cash flows for these businesses in 2011; howe ver, these planned levels are expected to continue to be significantly below the levels generated by these businesses during the first half of 2008.going forward into 2012.

Our operating cash flows continue to be affected by hurricanes.

During the past twothree years, Maritech has performed an extensive amount of well intervention, abandonment, decommissioning, debris removal, and platform construction associated with the six offshore platforms that were destroyed by Hurricanes Rita and Ike during 2005 and 2008, respectively. As of December 31, 2010,2011, Maritech has remaining work associated with two remainingof the downed platforms to be removed, and has begun redrilling certain wells at its East Cameron 328 field using a newly installed replacement platform. Until these wells are redrilled, production from the East Cameron 328 field continues to be below their pre-storm levels.platforms. The estimated cost to perform the remaining abandonment, decommissioning, and debris removal and well redrilling will beis approximately $50 to $65$27.5 million net to our interest before any in suranceinsurance recoveries. Due to the unique nature of the remaining work to be performed, actual costs could greatly exceed these estimates and, depending on the nature of any excess costs incurred, could result in significant charges to earnings in future periods. Approximately $38.1 millionAll of this amount has been accrued as part of Maritech’s decommissioning liabilities. An additional amount of approximately $13 to $19 million relates primarily to the estimated cost to finalize the newly installed offshore platform and to complete the redrilling of the wells at the East Cameron 328 location. Following the collection of $47.8 million of insurance settlement proceeds associated with Hurricane Ike during 2010, Maritech has additional maximum remaining insurance coverage available of approximately $19.5 million, all of which relates to Hurricane Ike. We anticipate that damages from Hurricane Ike, will exceed our coverage limits for this storm. Despite our confidence that the majority of the remaining abandonme nt, decommissioning, debris removal, and well redrilling costs up to our coverage limits will qualify as covered costs pursuant to our insurance coverage,although a portion of these coststhis coverage may not be reimbursed.utilized. One of the underwriters associated with our windstorm insurance coverage for Hurricane Ike damages has contested whether certain repair costs incurred are covered costs under the policy. During December 2010, we initiated legal proceedings against this underwriter in an attempt to collect the amount of claim reimbursements provided for under the policy. Also, theThe timing of the collection of any future reimbursements is beyond our control, and we will continue to use a significant amount of our working capital until such reimbursements are received.

The recent2010 explosion and subsequent oil spill at the Macondo well evidences the general operating risks associated with offshore oil and gas activities. While we have no liability associated with this specific incident, weWe are subject to operating hazards normally associated with the oilfield service industry operations and, to a lesser extent, offshore oil and gas production operations, including fires, explosions, blowouts, cratering, mechanical problems, abnormally pressured formations, and environmental accidents. We maintain various types of business insurance that would be applicable in the event of an explosion or other catastrophic event involving our offshore operations. This insurance includes third-party liability, workers’ compensation and employers’ liability, general liability, vessel pollution liability, and operational risk coverage for our Maritech o iloil and gas properties, including named windstorm damage, removal of debris, operator’s extra expense, control of well, and pollution and clean-up coverage. Our insurance coverage includes deductibles that must be met prior to recovery. Additionally, our insurance is subject to certain exclusions and limitations. We believe our policy of insuring against such risks, as well as the levels of insurance we maintain, is typical in the industry. In addition, we provide services and products in the offshore Gulf of Mexico generally pursuant to agreements
57

that create insurance and indemnity obligations for both parties. Our Maritech subsidiary maintains a formalized oil spill response plan that it submits to BOEMRE.BSEE. Maritech has designated employees and third-party contracts in place to ensure that resources are available as required in the event of an environmental accident. While it is impossible to anticipate every potential accident or incident involving our offshore operations, we believe we have taken appropriate steps to mitigate the potential impact of such an event on the environment in the regions in which we operate.

Future operating cash flow will continue to be affected by the oil and gas prices received for Maritech’s production. To minimize the risk of fluctuating oil and gas prices, Maritech enters into oil and natural gas swap derivative transactions that are designated to hedge a portion of Maritech’s oil and gas production. Maritech’s oil and natural gas swap derivative contracts during 2010 resulted in Maritech receiving a fixed price for hedged natural gas production that was in excess of prices currently being received. Following the expiration of its 2010 swap derivative contracts, Maritech’s natural gas production is currently unhedged and its hedged oil production is fixed at prices below current oil prices.

Investing Activities

During 2010,2011, we generated $46.8 million of cash flows from investing activities, due to approximately $188.3 million of proceeds received from asset sales, primarily from sales of Maritech oil and gas producing properties. Maritech has represented a significant portion of our capital expenditures historically, and with the sale of these Maritech properties, we have focused our investing activities on our existing businesses and on potential acquisitions. During 2011, we expended $115.9$123.6 million of cash capital expenditures, and other investing activities. This level ofthis amount included an increase in capital expenditures was significantly reducedfor each of our segments, other than Maritech, compared to the past several years, partially due toprior year. This increase in capital expenditures reflects the completion during 2009anticipated growth for each of our new corporate headquarterssegments, other than Maritech. In July 2011, we purchased a heavy lift derrick barge with a 1,600-metric ton lift capacity, fully revolving crane for approximately $62.8 million. Additional costs were also incurred for inspecting, transporting, and outfitting the barge prior to placing it into service in November 2011. This asset purchase significantly expanded the capability of our Offshore Services segment and enables us to serve customers with heavier structures in the Gulf of Mexico.

The Woodlands, Texas,recent growth in our Production Testing segment’s operations has resulted in plans to purchase significant additional equipment needed to serve the growing needs of our customers. This expenditure program is underway and our El Dorado, Arkansas, calcium chloride plant facility. In light of uncertainties regarding our future operating cash flows, ourexpected to continue into 2012. Our capital expenditure plans have been, and, for certain of our businesses, will continue to be, reviewed carefully, and a significant amount of suchplanned capital expenditures have beenexpenditure activity may be deferred until activity levels increase. This restraint on capital expenditure activity may also affect future growth. In particular, priorOur Compressco segment continues to 2009, we had invested significantly in Maritech acquisitionoperate at reduced levels of fabrication of new compressor units and development activities. The current effortexpects to reduce our investment in Maritech includes the suspensiondo so until demand for its services increases and inventories of oil and gas property acquisition activities and the reduction of oil and gas development activities. In addition, weavailable compressor units are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and we are reviewing opportunities to sell Maritech oil and gas property packages to industry participants and other third parties.reduced.

During 2010,2011, our cash capital expenditures totaled approximately $107.7$123.6 million. In addition, in December 2010, we expended $6.3 million for the acquisition of certain well abandonment and wireline assets for our Offshore Services segment. Approximately $10.9$17.9 million of our capital expenditures was expended by our Fluids Division, approximately $6.7 millionthe majority of which related to the ongoing modificationpurchase of our new calcium chloride plant facility.equipment to support its growing onshore completion services business. Our OffshoreProduction Enhancement Division expendedspent approximately $81.4$32.4 million, consisting of approximately $70.2 million of acquisition, exploration and development expenditures for Maritech. In addition, the Offshore Division expended approximately $11.3 million on its Offshore Services operations for costs on its various heavy lift and dive support vessels exclusive of the December 2010 acquisition. Our Production Enhanceme nt Division spent approximately $13.9 million, consisting of approximately $6.0$19.9 million by the Production Testing segment to replaceadd to or enhancereplace a portion of its production testing equipment fleet and approximately $7.9$12.5 million by the Compressco segment for customized compressor units to be sold, along with general infrastructure needs, along with minimal expansionneeds. Our Offshore Division expended approximately $72.3 million, consisting of approximately $64.4 million of expenditures by its Offshore Services segment, primarily for the heavy lift barge discussed above. In addition, the Offshore Division expended approximately $7.9 million of development expenditures for Maritech prior to the sale of substantially all of its wellhead compressor fleet.oil and gas properties. Corporate capital expenditures were approximately $1.4$1.0 million.

Generally, a significant majority of our planned capital expenditures is related to identified opportunities to grow and expand our existing businesses;businesses other than Maritech; however, certain of these expenditures may be postponed or cancelled in our continuing efforts to conserve capital. We plan to expend over $120$140 million on total capital expenditures during 2011. This anticipated level of capital expenditure activity would result in increased spending for each of our business segments other than Maritech and Compressco.2012. The deferral of certain capital projects, such as the additional replacement or upgrading of vessels in our Offshore Services fleet, could affect our ability to compete in the future. This restraint on capital expenditure activity may also affect future growth. However, ourOur long-term growth strategy also continues to include the pursuit of suitable acquisition sacquisitions or opportunities to establishexpand operations in additional niche oil and gas service markets. To the extent we consummate a significant transaction, our liquidity position will be affected.

Financing Activities

To fund our capital and working capital requirements, we may supplement our existing cash balances and cash flow from operating activities as needed from long-term borrowings, short-term borrowings, equity issuances, and other sources of capital.

Our Bank Credit Facilities

On October 29, 2010, we amended our existing bankWe have a revolving credit facility agreement with a syndicationsyndicate of banks whereby thepursuant to a credit facility agreement that was decreased from $300most recently amended in October 2010 (the Credit Agreement). As of February 29, 2012, we did not have any outstanding balance on the revolving credit facility, although we had $8.1 million to $278of letters of credit and guarantees against the $278.0 million and its scheduled maturity was extended from June 2011 to October 2015.availability under the revolving credit facility, leaving a net availability of $269.9 million. In addition, the amended credit facility agreement allows us to increase the facility by $150 million up to a $428 million limit upon the agreement of the lenders and the satisfaction of certain conditions. As of March 1, 2011, we did not have any outstanding balance on the amended revolving credit facility and had $14.2 million in letters of credit and guarantees against the $278.0 million amended revolving credit facility, leaving a net availability of $263.8 million.

Under the amended credit facility agreement (the Credit Agreement),Agreement, which matures on October 29, 2015, the revolving credit facility remainsis unsecured and guaranteed by certain of our material U.S. subsidiaries.subsidiaries (excluding Compressco). Borrowings generally bear interest at the British Bankers Association LIBOR rate plus 1.5% to 2.5%, depending on one of our financial ratios. We pay a commitment fee ranging from 0.225% to 0.500% on unused portions of the facility. Similar to the previous terms, theThe Credit Agreement contains customary covenants and other restrictions, including certain financial ratio covenants involving our levels of debt and interest cost compared to a defined measure of our operating cash flows over a twelve month period. In addition, the Credit Agreement includes limitations on aggregate asset sales, individual acquisitions, and aggregate annual acquisitions and capital expenditures. Ac cessAccess to our revolving credit line is dependent upon our ability to comply with the certain financial ratio covenants set forth in the Credit Agreement, as discussed above. Significant deterioration of the financial ratios could result in a default under the Credit Agreement and, if not remedied, could result in termination of the agreement and acceleration of any outstanding balances. In June 2011, associated with the contribution of the majority of the operations and related assets and liabilities of our Compressco segment into Compressco Partners, Compressco Partners was designated as an unrestricted subsidiary and is no longer a borrower or a guarantor under our bank credit facility.

The Credit Agreement also includes cross-default provisions relating to any other indebtedness greater than a defined amount. If any such indebtedness is not paid or is accelerated and such event is not remedied in a timely manner, a default will occur under the Credit Agreement. Our Credit Agreement also contains a covenant that restricts us from paying dividends in the event of a default or if such payment would result in an event of default. We are in compliance with all covenants and conditions of our Credit Agreement
53

as of December 31, 2010.2011. Our continuing ability to comply with these financial covenants depends largely upon our ability to generate adequate cash flow. Historically, our financial performance has been more than adequate to meet these covenants and we expect this trend to continue.

Senior NotesCompressco Partners’ Bank Credit Facility

On June 24, 2011, Compressco Partners entered into a new credit agreement (the Partnership Credit Agreement) with JPMorgan Chase Bank, N.A. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all of its existing and future, direct and indirect, domestic subsidiaries are guarantors. We are not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement includes borrowing capacity of $20.0 million (less $3.0 million that is required to be set aside as a reserve that cannot be borrowed) that is available for letters of credit (with a sublimit of $5.0 million) and an uncommitted $20.0 million expansion feature. The Partnership Credit Agreement may be used to fund Compressco Partners’ working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future acquisitions. So long as Compressco Partners is not in default, the Partnership Credit Agreement could also be used to fund Compressco Partners’ quarterly distributions. Borrowings under the Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. As of December 31, 2011, there is no balance outstanding under the Partnership Credit Agreement. The maturity date of the Partnership Credit Agreement is June 24, 2015.

All obligations under the Partnership Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first lien security interest in substantially all of the assets (excluding real property) of Compressco Partners and its existing and future, direct and indirect domestic subsidiaries, and all of the capital stock of its existing and future, direct and indirect subsidiaries (limited, in the case of foreign subsidiaries, to 65% of the capital stock of first tier foreign subsidiaries).

Borrowings under the Partnership Credit Agreement bear interest at a rate per annum equal to, at Compressco Partners’ option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as we select) plus a margin of 2.25% per annum or (b) a base rate determined by reference to the highest of (1) the prime rate of interest announced from time to time by JPMorgan Chase Bank, N.A. or (2) LIBOR (adjusted to reflect any required bank reserves) for a one-month interest period on such day plus 2.50% per annum. In September 2004, we issued,addition to paying interest on any outstanding principal under the Partnership Credit Agreement, Compressco Partners is required to pay customary collateral monitoring fees and sold throughletter of credit fees, including without limitation, a private placement, $55.0 million in aggregate principal amountletter of Series 2004-A Senior Notescredit fee equal to the applicable margin on revolving credit LIBOR loans and 28 million Euros in aggregate principal amountfronting fees.

The Partnership Credit Agreement requires Compressco Partners to maintain a minimum interest coverage ratio (ratio of Series 2004-B Senior Notes pursuant to a Master Note Purchase Agreement. In December 2010 we used the proceeds from our Series 2010 Senior Notes and applied $95.7 million to repay the Series 2004 Senior Notes, including principal, accruedearnings before interest and taxes to interest) of 2.5 to 1.0 as of the last day of any fiscal quarter, calculated on a $2.8 million “make-whole” prepayment premium.trailing four quarter basis, whenever availability is less than $5 million. In addition, the Partnership Credit Agreement includes customary negative covenants, which, among other things, limit Compressco Partners’ ability to incur additional debt, incur, or permit certain liens to exist, or make certain loans, investments, acquisitions, or other restricted payments. The Partnership Credit Agreement provides that Compressco Partners can make distributions to holders of its common and subordinated units, but only if there is no default or event of default under the facility. If an event of default occurs, the lenders are entitled to take various actions, including the acceleration of amounts due under the Partnership Credit Agreement and all actions permitted to be taken by secured creditors.

Senior Notes

In April 2006, we issued, and sold through a private placement, $90.0 million in aggregate principal amount of Series 2006-A Senior Notes pursuant to our existing Master Note Purchase Agreement dated September 2004, as supplemented as of April 18, 2006. The Series 2006-A Senior Notes bear interest at the fixed rate of 5.90% and mature on April 30, 2016. Interest on the 2006-A Senior Notes is due semiannually on April 30 and October 30 of each year. The Series 2006-A Senior Notes were sold in the United States to accredited investors pursuant to an exemption from the Securities Act of 1933. Net proceeds from the sale of the Series 2006-A Senior Notes were used to pay down a portion of the existing indebtedness under the bank revolving credit facility.

54

In April 2008, we issued, and sold through a private placement, $35.0 million in aggregate principal amount of Series 2008-A Senior Notes and $90.0 million in aggregate principal amount of Series 2008-B Senior Notes (collectively the Series 2008 Senior Notes) pursuant to a Note Purchase Agreement dated April 30, 2008. The Series 2008-A Senior Notes bear interest at the fixed rate of 6.30% and mature on April 30,

Interest on the 2008 Senior Notes is due semiannually on April 30 and October 31 of each year. The Series 2008 Senior Notes were sold in the United States to accredited investors pursuant to an exemption from the Securities Act of 1933. A significant majority of the combined net proceeds from the sale of the Series 2008 Senior Notes was used to pay down a portion of the existing indebtedness under the bank revolving credit facility.

In SeptemberDecember 2010, we entered into an agreement whereby we agreed to issueissued, and sellsold through a private placement, $65.0 million in aggregate principal amount of Series 2010-A Senior Notes and $25.0 million in aggregate principal amount of Series 2010-B Senior Notes (collectively, the 2010 Senior Notes) pursuant to a Note Purchase Agreement dated September 30, 2010. Upon receipt of the proceeds in December 2010, we utilized the funds to repay the 2004 Senior Notes. The Series 2010-A Senior Notes bear interest at the fixed rate of 5.09% and mature on December 15, 2017. The Series 2010-B Senior Notes bear interest at the fixed rate of 5.67% and mature on December 15, 2020. Interest on the 2010 Senior Notes is due semiannually on June 15 and December 15 of each year.

We may prepay the Senior Notes, in whole or in part, at any time at a price equal to 100% of the principal amount outstanding, plus accrued and unpaid interest and a “make-whole” prepayment premium. The Senior Notes are unsecured and are guaranteed by substantially all of our wholly owned U.S. subsidiaries. The Note Purchase Agreement and the Master Note Purchase Agreement, as supplemented, contain customary covenants and restrictions and require us to maintain certain financial ratios, including a minimum level of net worth and a ratio between our long-term debt balance and a defined measure of operating cash flow over a twelve month period. The Note Purchase Agreement and the Master Note Purchase Agreement also contain customary default provisions as well as a cross-default provision relating to any other of our indebtedness of $20 m illionmillion or more. We are in compliance with all covenants and conditions of the Note Purchase Agreement and the Master Note Purchase Agreement as of December 31, 2010.2011. Upon the occurrence and during the continuation of an event of default under the Note Purchase AgreementAgreements and the Master Note Purchase Agreement, as supplemented, the Senior Notes may become immediately due and payable, either automatically or by declaration of holders of more than 50% in principal amount of the Senior Notes outstanding at the time.

Other Sources

In addition to the aforementioned revolving credit facility, we fund our short-term liquidity requirements from cash generated by operations, from short-term vendor financing and, to a lesser extent, from leasing with institutional leasing companies. Should additional capital be required, we believe that we have the ability to raise such capital through the issuance of additional debt or equity. However, instability or volatility in the capital markets at the times we need to access capital may affect the cost of capital and the ability to raise capital for an indeterminable length of time. As discussed above, our Credit Agreement matures in 2015 and our Senior Notes mature at various dates between April 2013 and December 2020. The replacement of these capital sources at similar or more favorable terms is not certain. If it is necessary to utilize equity to fund our capital needs, dilution to our common stockholders could occur.
 
In November 2009, we filed a universal shelf registration statement on Form S-3 that permits us to issue an indeterminate amount of securities including common stock, preferred stock, senior and subordinated debt securities, warrants, and units. Such securities may be used for working capital needs, capital expenditures, and expenditures related to general corporate purposes, including possible future acquisitions. In May 2004, we filed a universal acquisition shelf registration statement on Form S-4 that permits us to issue up to $400 million of common stock, preferred stock, senior and subordinated debt securities, and warrants in one or more acquisition transactions that we may undertake from time to time.

In January 2004, our Board of Directors authorized the repurchase of up to $20 million of our common stock. We purchased $5.7 million of common stock pursuant to this authorization from 2004 through 2005 and have made no purchases pursuant to the authorization since then. We received $3.4 million, $1.3 million, and $1.2 million during 2011, 2010 and $4.8 million during 2010, 2009, and 2008, respectively, from the exercise of stock options by employees.

Off Balance Sheet Arrangements

An “off balance sheet arrangement” is defined as any contractual arrangement to which an entity that is not consolidated with us is a party, under which we have, or in the future may have:
 
·  any obligation under a guarantee contract that requires initial recognition and measurement under U.S. Generally Accepted Accounting Principles;
 
·  a retained or contingent interest in assets transferred to an unconsolidated entity or similar arrangement that serves as credit, liquidity, or market risk support to that entity for the transferred assets;
 
·  any obligation under certain derivative instruments; or
 
·  any obligation under a material variable interest held by us in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to us, or engages in leasing, hedging, or research and development services with us.

As of December 31, 20102011 and 2009,2010, we had no “off balance sheet arrangements” that may have a current or future material effect on our consolidated financial condition or results of operations.

Commitments and Contingencies

Litigation

We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Class Action Lawsuit

Between March 27, 2008, and April 30, 2008, two putative class action complaints were filed in the United States District Court for the Southern District of Texas (Houston Division) against us and certain former officers by certain stockholders on behalf of themselves and other stockholders who purchased our common stock between January 3, 2007, and October 16, 2007. The complaints assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On May 8, 2008, the Court consolidated these complaints as In re TETRA Technologies, Inc. Securities Litigation, No. 4:08-cv-0965 (S.D. Tex.). On June 16, 2010, defendants and plaintiff’s counsel reached a settlement agreement whereby all claims against defendants will be re leased in exchange for a payment of $8.25 million, which was subsequently paid by our insurers. On September 29, 2010, the Court approved the settlement and entered the Order and Final Judgment terminating the class action lawsuit.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in thea federal class action lawsuit and thewhich was settled during 2010. The claims are for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court con solidatedconsolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit was stayed by agreement of the parties pending the Court’s ruling on our motion to dismiss the federal class action. On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit.lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff’s inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff’s counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. Our board is curren tly evaluatingOn August 22, 2011, the best courseCourt issued a Preliminary Approval Order preliminarily approving the settlement of action to take in response to the demand letter.

At this stage, it is impossible to predict the outcome of these proceedings or their impact upon us. We continue to believe that the allegations madesuit as set forth in the derivative lawsuits are without merit,Stipulation of Settlement dated August 12, 2011 (the Stipulation). The Stipulation does not provide for the payment of monetary compensation to stockholders; rather, it provides for certain additions to our corporate governance policies and we intend to seek dismissalprocedures and for the payment of plaintiff’s attorneys’ fees and vigorously defend against this lawsuit. While a successful outcome cannot be guaranteed, we do not reasonably expect this lawsuit tolitigation expenses, which have a material adverse effect.been paid by our insurers. On October 17, 2011, the Court granted final approval of the settlement.

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

In August of 2009, the Environmental Protection Agency (EPA), pursuant to Sections 308 and 311 of the Clean Water Act (CWA), served a request for information with regard to a release of zinc bromide that occurred from one of our transport barges on the Mississippi River on March 11, 2009. We timely filed a response to that request for information in August 2009. In January 2010, the EPA issued a Notice of Violation and Opportunity to Show Cause related to the spill. We met with the EPA in April 2010 to discuss potential violations and penalties. It has been agreed that no injunctive relief will be required. We have finalized a joint stipulation of settlement with the EPA whereby we are responsible for a penalty of $487,000, which has been submitted to the Department of Justice for approval. We expect to pay this penalty amount during the second qu arter of 2011 and expect the full amount to be covered by insurance.

Product Purchase Obligations

In the normal course of our Fluids Division operations, we enter into supply agreements with certain manufacturers of various raw materials and finished products. Some of these agreements have terms and conditions that specify a minimum or maximum level of purchases over the term of the agreement. Other agreements require us to purchase the entire output of the raw material or finished product produced by the manufacturer. Our purchase obligations under these agreements apply only with regard to raw materials and finished products that meet specifications set forth in the agreements. We recognize a liability for the purchase of such products at the time we receive them. As of December 31, 2010,2011, the aggregate amount of the fixed and determinable portion of the purchase obligation pursuant to our Fluids Division’s supply agreements was approxi mately $266.4approximately $250.6 million, extending through 2029.

Other Contingencies

Related to its acquired interests inremaining oil and gas properties,property decommissioning liabilities, our Maritech subsidiary estimates the third-party fair values (including an estimated profit) to plug and abandon wells, decommission the pipelines and platforms, and clear the sites, and uses these estimates to record Maritech’s decommissioning liabilities, net of amounts allocable to joint interest owners and any amounts contractually agreed to be paid in the future by the previous owners of the properties. In some cases, previous owners of acquired oil and gas properties are contractually obligated to pay Maritech a fixed amount for the future well abandonment and decommissioning work on these properties as such work is performed. As of December 31, 2010,2011, Maritech’s decommissioning liabilities are net of approximately $35.9$7.0 million for such future reimbursements from these previous owners.

(1)Decommissioning liabilities related to oil and gas properties generally must be satisfied within twelve months after a property’s lease expires. Lease expiration generally occurs six months after the last producing well on the lease ceases production. We have estimated the timing of these payments for decommissioning liabilities based upon anticipated lease expiration dates,our plans and the plans of outside operators, which are subject to many changing variables, including the estimated life of the producing oil and gas properties, which is affected by changing oil and gas commodity prices. The amounts shown represent the undiscounted obligation as of December 31, 2010.2011.
(2)Amounts exclude other long-term liabilities reflected in our Consolidated Balance Sheet that do not have known payment streams. These excluded amounts include approximately $3.6$3.0 million of liabilities under FASB Codification Topic 740, “Accounting for Uncertainty in Income Taxes,” as we are unable to reasonably estimate the ultimate amount or timing of settlements. See “Note F – Income Taxes,” in the Notes to Consolidated Financial Statements for further discussion.

Recently IssuedNew Accounting Pronouncements

In October 2009,September 2011, the Financial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2009-13, “Revenue Recognition2011-08, “Intangibles – Goodwill and Other (Topic 605)350), Multiple Deliverable Revenue Arrangements,”Testing Goodwill for Impairment” (ASU 2011-08), which establishessimplifies how entities test goodwill for impairment. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the accounting andfair value of a reporting guidanceunit is less than its carrying amount as a basis for arrangements under which service providers willdetermining whether it is necessary to perform multiple revenue-generating activities. Specifically, this guidance addresses how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. Additional disclosures of multiple deliverable arrangements will also be required.the two-step goodwill impairment test described in Topic 350. The ASU 2009-13 is effective prospectively for revenue arrangements entered into or materially modified inannual and interim goodwill impairment tests performed for fiscal years beginning on or after JuneDecember 15, 2010.2011. Early adoption is permitted. The adoption of ASU 2011-08 did not have a significant impact on our financial statements.
57

In June 2011, the FASB published ASU 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), which has the objective of improving the comparability, consistency, and transparency of financial reporting and increasing the prominence of items reported in other comprehensive income. As part of ASU 2011-05, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity, among other amendments in this ASU. The amendments require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this ASU are to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are to be applied retrospectively. In December 2011, with the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standard Update No. 2011-05,” the FASB announced that it has deferred certain aspects of ASU 2011-05. The adoption of the accounting and disclosure requirements of this AS UASU is not expected to have a significant impact on our financial statements.

In May 2011, the FASB published ASU 2011-04, “Fair Value Measurement (Topic 820) – Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” whereby the FASB and the International Accounting Standards Board (IASB) aligned their definitions of fair value such that their fair value measurement and disclosure requirements are the same (except for minor differences in wording and style). The Boards concluded that the amendments in this ASU will improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The amendments in this ASU are effective during interim and annual periods beginning after December 15, 2011, and are to be applied prospectively. The adoption of the accounting and disclosure requirements of this ASU will not have a significant impact on our financial statements.

In January 2010, the FASB published ASU 2010-06, “Fair Value Measurements and Disclosures (Topic 820), Improving Disclosures about Fair Value Measurements,” which requires new disclosures about transfers in and out of fair value hierarchy levels, requires more detailed disclosures about activity in Level 3 fair value measurements, and clarifies existing disclosure requirements about asset and liability aggregation, inputs, and valuation techniques. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosure requirements of activity in Level 3 fair value measurements, which become effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. The adoption of the disclosu re requirements of this ASU did not have a significant impact on our financial statements, and the disclosure requirements of activity in Level 3 fair value measurements will not have a significant impact on our financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

Interest Rate Risk

Any balances outstanding under the floating rate portion of our bank credit facility or Compressco Partners' bank credit facility are subject to market risk exposure related to changes in applicable interest rates. We borrow funds pursuant to our bank credit facility as necessary to fund our capital expenditure requirements and certain acquisitions. Compressco Partners' bank credit facility is available to fund its working capital needs, capital expenditures, acquisitions, and other general partnership purposes. These instruments carry interest at an agreed-upon percentage rate spread above LIBOR. We had no balance outstanding under oureither bank credit facility as of December 31, 2010.2011. Accordingly, as of that date, there are no long-term debt obligations which bear a variable rate of interest.

Exchange Rate Risk

We are exposed to fluctuations between the U.S. dollar and the euro with regard to our euro-denominated operating activities. In September 2004,As of December 31, 2011, we borrowed euros to fund the acquisition of our European calcium chloride assets. We entered into long-term euro-denominated borrowings, in order to provide a natural currency hedge for our euro-based operating cash flow. In December 2010, we repaid our euro denominated debt and currently have no currency hedge for our euro-denominated operations. In our European operations, we continue to have exposure related to revenues, expenses, operating receivables, and payables denominated in euros, as well as other currencies; however, such transactions are not pursuant to long-term contract terms, and the amount of such foreign currency exposure is not determinable or considered material. We also have operation soperations in other foreign countries, particularly in Brazil and Mexico, in which we have exposure to the fluctuation between the local currencies in those markets and the U.S. dollar. We currently have no hedges in place with regard to these currencies.

58


Commodity Price Risk

We have market risk exposure in the pricing applicable to our oil and gas production. Realized pricing is primarily driven by the prevailing worldwide price for crude oil and spot prices in the U.S. natural gas market. Historically, prices received for oil and gas production have been volatile and unpredictable, and such price volatility is expected to continue. Our risk management activities involve the use of derivative financial instruments, such as swap agreements, to hedge the impact of market price risk exposures for a portion of our oil and gas production. We
In April 2011, in connection with the anticipated plans to sell Maritech’s remaining oil and gas properties, we liquidated the derivative swap financial instruments that were designated as hedges of Maritech’s future oil production. As a result, until Maritech’s remaining oil and gas properties are sold, we are exposed to the volatility ofcommodity price risk associated with the remaining oil and gas prices for the portion of our oil andnatural gas production that we continue to own following the sales. Due to the minimal amount of expected production following the sales, such commodity price risk exposure is not hedged. Net of the impact of the crude oil hedges as of December 31, 2010, described below, each $1 per barrel decrease in future crude oil prices would result in a decrease in after tax earnings of $0.3 million. As of December 31, 2010, we have no natural gas hedges, therefore, each decrease in future gas prices of $0.10 per Mcf would result in a decrease in after tax earnings of $0.5 million.expected to be significant.

FASB Codification Topic 815, “Derivatives and Hedging,” requires companies to record derivatives on the balance sheet as assets and liabilities, measured at fair value. Gains or losses resulting from changes in the values of those derivatives are accounted for depending on the use of the derivative and whether it qualifies for hedge accounting. As of December 31, 2010, and 2009, we had the following cash flow hedging swap contracts outstanding relating to a portion of our Maritech subsidiary’s oil and gas production:

Commodity Contracts 
Aggregate
Daily Volume
 Weighted Average Contract Price Contract Year
December 31, 2010      
Oil swaps 2,000 barrels/day $87.68/barrel 2011
December 31, 2009
Oil swaps2,000 barrels/day$78.70/barrel2010
Natural gas swaps20,000 MMBtu/day$8.147/MMBtu2010

Each oil and gas swap contract uses the NYMEX WTI (West Texas Intermediate) oil price and the NYMEX Henry Hub natural gas price as the referenced price. Based upon an average NYMEX strip price over the remaining contract term of $93.76/barrel, the market value of our oil swaps liability at December 31, 2010, was $5.2 million. A $1 increase in the future price of oil would resulthave resulted in the market value of the combined oil derivative liability increasing by $0.7 million. The market value associated with the 2011 oil swap
64

contract is reflected as a current liability as of December 31, 2010, in the accompanying consolidated balance sheet.

Based upon an average NYMEX strip price over the remaining contract term of $82.31/barrel, the market value of our oil swaps liability at December 31, 2009 was $2.6 million. A $1 increase in the future price of oil would result in the market value of the combined oil derivative liability increasing by $0.7 million. Based on an average NYMEX strip price over the remaining contract term of $5.79/MMBtu, the market value of our natural gas swaps asset at December 31, 2009 was $19.9 million. A $0.10 increase in the future price of natural gas would result in the market value of the combined natural gas derivative asset decreasing by $0.7 million. As of December 31, 2009, the market value associated with the 2010 natural gas swap contracts is reflected as a current asset, and the market value associated with the 2010 oil swap contracts is reflected as a current liability in the accompanying consolidated balance sheet.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, an evaluation of the effectiveness of our internal control over financial reporting was conducted based on the framework in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on that evaluation under the framework in Internal Control – Integrated Framework issued by the COSO, our management concluded that our internal control over financial reporting was effective as of December 31, 2010.2011.

An assessment of the effectiveness of our internal control over financial reporting as of December 31, 2010,2011, has been performed by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the fiscal quarter ending December 31, 2010,2011, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information.

In connection with the preparation of our financial statements for the period ended December 31, 2010, we determined that a charge of approximately $40.7 million for the partial impairment of Maritech oilNone.

and gas properties was required. The impairment charge primarily resulted from the impact of increased estimated asset retirement obligations during the fourth quarter of 2010. The oil and gas property impairment charge will not result in future capital expenditures. The disclosure set forth in this Item 9B is included in this Annual Report on Form 10-K in accordance with instructions to Item 2.06 of Form 8-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Board of Directors and Stockholders of
TETRA Technologies, Inc.

We have audited the accompanying consolidated balance sheets of TETRA Technologies, Inc. and subsidiaries as of December 31, 20102011 and 2009,2010, and the related consolidated statements of operations, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2010.2011. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of TETRA Technologies, Inc. and subsidiaries at December 31, 20102011 and 2009,2010, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2010,2011, in conformity with U.S. generally accepted accounting principles.

As discussed in Notes B andNote R to the consolidated financial statements, in 2009, the Company adopted SEC Release 33-8995 and the amendments to ASC Topic 932, “Extractive Industries – Oil and Gas,” resulting from ASU 2010-03 (collectively, the Modernization Rules).

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), TETRA Technologies, Inc.’s internal control over financial reporting as of December 31, 2010,2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 1, 2011,February 29, 2012, expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 
Board of Directors and Stockholders of
TETRA Technologies, Inc.

We have audited TETRA Technologies, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2010,2011, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). TETRA Technologies, Inc. and subsidiaries’ management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, TETRA Technologies, Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010,2011, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of TETRA Technologies, Inc. and subsidiaries as of December 31, 20102011 and 2009,2010, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 20102011 of TETRA Technologies, Inc. and subsidiaries, and our report dated March 1, 2011,February 29, 2012, expressed an unqualified opinion thereon.

TETRA TECHNOLOGIES, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

December 31, 20102011

NOTE A — ORGANIZATION AND OPERATIONS

We are a geographically diversified oil and gas services company focused on completion fluids and otherassociated products and services, production testing, wellhead compression, and selected offshore services including well plugging and abandonment, decommissioning, and diving, withdiving. We also have a concentratedlimited domestic exploration and production business. We were incorporated in Delaware in 1981. We are composed of five reporting segments organized into three divisions – Fluids, Offshore,Production Enhancement, and Production Enhancement.Offshore. Unless the context requires otherwise, when we refer to “we,” “us,” and “our,” we are describing TETRA Technologies, Inc. and its consolidated subsidiaries on a consolidated basis.

Our Fluids Division manufactures and markets certain clear brine fluids, additives, and other associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations both in the United States and in certain regions ofcountries in Latin America, Europe, Asia, the Middle East, and Africa. The Division also markets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies in the construction or decommissioning of offshore oil and gas production platforms and pipelines, and (3) diving services involving conventional and saturated air diving.
The Maritech segment is an oil and gas exploration, development, and production operation focused in the offshore, inland waters, and onshore U.S. Gulf Coast region. The Offshore Division’s Offshore Services segment performs a significant portion of the well plugging, abandonment, and decommissioning services required by Maritech.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides production testing services in many of the major oil and gas basins in the United States, as well asStates. In addition, the Production Testing segment has operations in certain onshore basins in certain regions in Mexico, Brazil, NorthernNorth Africa, the Middle East, and other internationalforeign markets.

The Compressco segment provides wellhead compression-based and other production enhancement services throughout mostmany of the onshore producing regions of the United States, as well as certain onshore basins in Mexico, Canada, Mexico,and certain countries in South America, Europe, Asia, and other international locations. Beginning June 20, 2011, the Compressco segment performs the significant majority of its operations through its publicly traded limited partnership, Compressco Partners, L.P.
 
Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.
The Maritech segment is an oil and gas exploration, development, and production operation focused in the offshore and onshore U.S. Gulf Coast region. During 2011, Maritech sold approximately 95% of the proved reserves it owned as of December 31, 2010, and is seeking to sell its remaining oil and gas producing property interests. Maritech’s remaining operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells, facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division’s Offshore Services segment.

NOTE B — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of our wholly owned subsidiaries. Investments in unconsolidated joint ventures in which we participate are accounted for using the equity method. Our interests in oil and gas properties are proportionately consolidated. All significant intercompany accounts and transactions have been eliminated in consolidation.

F-8


Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclose contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

F-8


Reclassifications

We have accounted for the discontinuance or disposal of certain businesses as discontinued operations and have reclassified prior period financial statements to exclude these businesses from continuing operations. See Note C – Discontinued Operations, for a further discussion of the discontinuance of these businesses.

Certain other previously reported financial information has also been reclassified to conform to the current year's presentation.

Cash Equivalents

We consider all highly liquid investments, with a maturity of three months or less when purchased, to be cash equivalents.Approximately $17.5 million of our consolidated cash and cash equivalents as of December 31, 2011 is held by Compressco Partners, L.P., and is unavailable for our general purposes.

Restricted Cash

Restricted cash reflectedis classified as a current asset when it is expected to be repaid or settled in the next twelve month period. Restricted cash on our balance sheetssheet as of December 31, 20102011, consists primarily of escrowed cash associated with our July 2011 purchase of a new heavy lift derrick barge. The escrowed cash will be included in restricted cash and 2009released to the sellers in accordance with the terms of the escrow agreement. Restricted cash on our balance sheet as of December 31, 2010 includes escrowed funds related to agreed repairs to be expended at one of our former Fluids Division facility locations. Thislocations, and this cash will remain restricted until such time aswas assigned to the associated project is completed, which we expect to occurlandowner of the facility during the next twelve months.2011.

Financial Instruments

Financial instruments that subject us to concentrations of credit risk consist principally of trade receivables with companies in the energy industry. Our policy is to evaluate, prior to providing goods or services, each customer's financial condition and to determine the amount of open credit to be extended. We generally require appropriate, additional collateral as security for credit amounts in excess of approved limits. Our customers consist primarily of major, well-established oil and gas producers and independent oil and gas companies. OurPrior to April 2011, our risk management activities currently involveinvolved the use of derivative financial instruments, such as oil and gas swap contracts, to hedge the impact of commodity market price risk exposures related to a portion of our oil and gas production cash flow. All of our oil and gas swap contracts were liquidated in April 2011 in connection with the sales of Maritech oil and gas producing properties.

To the extent we have any outstanding balance under our variable rate bank credit facility,facilities, we may face market risk exposure related to changes in applicable interest rates. Although we have no interest rate swap contracts outstanding to hedge this potential risk exposure, we have entered into certain fixed interest rate notes, which are scheduled to mature at various dates from 2013 through 2020 and which mitigate this risk on our total outstanding borrowings.

Allowances for Doubtful Accounts

Allowances for doubtful accounts are determined generally and on a specific identification basis when we believe that the collection of specific amounts owed to us is not probable.The changes in allowances for doubtful accounts for the three year period ended December 31, 2011, are as follows:

  Year Ended December 31,

     Total inventories $99,985  $104,305 
 
Finished goods inventories include, in addition to newly manufactured clear brine fluids, recycled brines that are repurchased from certain of our customers. Recycled brines are recorded at cost, using the weighted average method.

Property, Plant, and Equipment

Property, plant, and equipment are stated at the cost of assets acquired. Expenditures that increase the useful lives of assets are capitalized. The cost of repairs and maintenance is charged to operations as incurred. For financial reporting purposes, we generally provide for depreciation using the straight-line method over the estimated useful lives of assets, which are generally as follows:

Buildings15 – 2540 years
Barges and vessels5 – 30 years
Machinery vessels, and equipment321520 years
Automobiles and trucks4 years
Chemical plants15 – 30 years

Leasehold improvements are depreciated over the shorter of the remaining term of the associated lease or its useful life. Depreciation and depletion expense, excluding long-lived asset impairments and dry hole costs, for the years ended December 31, 2011, 2010, and 2009 and 2008 was $87.7 million, $139.7 million, $137.8 million, and $138.0$137.8 million, respectively.

Interest capitalized for the years ended December 31, 2011, 2010, and 2009 and 2008 was $1.2 million, $1.1 million, $6.8 million, and $3.2$6.8 million, respectively.

Oil and Gas Properties

Prior to our decision to sell Maritech’s oil and gas properties during 2011, Maritech conductsconducted oil and gas exploration, development, and production activities. Maritech periodically purchasespurchased oil and gas properties and assumesassumed the related well abandonment and decommissioning liabilities (referred to as decommissioning liabilities). We followfollowed the successful efforts method of accounting for our oil and gas operations. Under the successful efforts method, the costs of successful exploratory wells and leases are capitalized. Costs incurred to drill and equip development wells, including unsuccessful development wells, are capitalized. Other costs such as geological and geophysical costs, drilling costs of unsuccessful exploratory wells, and all internal costs are expensed. Maritech’s property purchases arewere recorded at the fair value of our working interest share of decommis sioningdecommissioning liabilities assumed, plus or minus any cash or other consideration paid or received as part of the transaction. All capitalized costs are accumulated and recorded separately for each field and allocated to leasehold costs and well costs. LeaseholdPrior to being classified as oil and gas properties held for sale, leasehold costs arewere depleted on a unit of production method based on the estimated remaining equivalent proved oil and gas reserves of each field. Well costs arewere depleted on a unit of production method based on the estimated remaining equivalent proved developed oil and gas reserves of each field. During the second quarter of 2011, we reclassified Maritech’s remaining oil and gas properties to Oil and Gas Properties Held for Sale in our consolidated balance sheet, and have recorded their value at fair value, less cost to dispose.

Intangible Assets other than Goodwill

Patents, trademarks, and other intangible assets are recorded on the basis of cost and are amortized on a straight-line basis over their estimated useful lives, ranging from 3 to 20 years. During 2011, as part of an acquisition consummated during the year, we acquired intangible assets having a fair value of approximately $1.4 million with estimated useful lives ranging from 3 to 6 years (having a weighted average useful life of 5.6 years). During 2010, as a part of an acquisition consummated during the year, we acquired intangible assets having a fair value of approximately $0.6 million with estimated useful lives ranging from 3 to 6 years (having a weighted average useful life of 5.3 years). During 2007, as a part of certain acquisitions consummated during the year, we acquired intangible assets having a fair value of approximately $2.4 million with estimated useful lives ranging from 2 to 6 years (having a weighted average useful life of 5.5 years). Amortization expense of patents, trademarks, and other intangible assets was $2. 8$2.8 million, $3.6$2.8 million, and $4.5$3.6 million for the twelve months ended December 31, 2011, 2010, 2009, and 2008,2009, respectively, and is included in operating income.depreciation, depletion, amortization and accretion. The estimated future annual amortization expense of patents, trademarks, and other intangible assets is $2.3 million for 2011, $2.2$2.4 million for 2012, $1.7$2.1 million for 2013, $0.7$1.0 million for 2014, and $0.7$0.9 million for 2015.2015, and $0.8 million for 2016.

Goodwill

Goodwill represents the excess of cost over the fair value of the net assets of businesses acquired in purchase transactions. We perform a goodwill impairment test on an annual basis or whenever indicators of impairment are present. We perform the annual test of goodwill impairment following the fourth quarter of each year. TheBeginning in 2011, the annual assessment for goodwill impairment begins with a qualitative assessment of whether it is “more likely than not” that the fair value of each reporting unit is less than its carrying value. This qualitative assessment requires the evaluation, based on the weight of evidence, of the significance of all identified events and circumstances for each reporting unit. Based on this qualitative assessment, we determined that it was not “more likely than not” that the fair values of any of our reporting units were less than their carrying values as of December 31, 2011. If the qualitative analysis indicates that it is “more likely than not” that a reporting unit’s fair value is less than its carrying value, the resulting goodwill impairment test consistswould consist of a two-step accounting test performed on a reporting unit basis. For purposes of this impairment test, the reporting units are our five reporting segments: Fluids, Offshore Services, Maritech, Production Testing, and Compressco. The first step of the impairment test, if required, is to compare the estimated fair value of any reporting units that have recorded goodwill with the recorded net book value (including goodwill) of the reporting unit. If the esti matedestimated fair value of the reporting unit is higher than the recorded net book value, no impairment is deemed to exist and no further testing is required. If, however, the estimated fair value of the reporting unit is below the recorded net book value, then a second step must be performed to determine the goodwill impairment required, if any. In this second step, the estimated fair value from the first step is used as the purchase price in a hypothetical acquisition of the reporting unit. Purchase business combination accounting rules are followed to determine a hypothetical purchase price allocation to the reporting unit’s assets and liabilities. The residual amount of goodwill that
F-11

results from this hypothetical purchase price allocation is compared to the recorded amount of goodwill for the reporting unit, and the recorded amount is written down to the hypothetical amount, if lower.

Because quoted market prices for our reporting units are not available, management must apply judgment in determining the estimated fair value of these reporting units for purposes of performing the goodwill impairment test. Management uses all available information to make these fair value determinations, including the present value of expected future cash flows using discount rates commensurate with the risks involved in the assets. The resultant fair values calculated for the reporting units are then compared to observable metrics for other companies in our industry, or on mergers and acquisitions in our industry, to determine whether those valuations, in our judgment, appear reasonable. We have estimated the fair value of each reporting unit based upon the future discounted cash flows of the busi nesses to which goodwill relates and have determined that there is no impairment of the goodwill recorded as of December 31, 2010.

During the fourth quarter of 2008, changes to the global economic environment resulting in uncertain capital markets and reductions in global economic activity had severe adverse impacts on stock markets and oil and natural gas prices, both of which contributed to a significant decline in our company’s stock price and corresponding market capitalization. For most of the fourth quarter, our market capitalization was below the recorded net book value of our balance sheet, including goodwill. The accounting principles regarding goodwill acknowledge that the observed market prices of individual trades of a company’s stock (and thus its computed market capitalization) may not be representative of the fair value of the company as a whole. Substantial value may arise from the ability to take adv antage of synergies and other benefits that flow from control over another entity. Consequently, measuring the fair value of a collection of assets and liabilities that operate together in a controlled entity is different from measuring the fair value of a single share of that entity’s common stock. Therefore, once the fair values of the reporting units were determined, we also added a control premium to the calculations. This control premium is judgmental and is based on observed mergers and acquisitions in our industry.

After determining the fair values of our various reporting units which had recorded goodwill as of December 31, 2008, it was determined that our Production Testing and Compressco reporting units passed the first step of the goodwill impairment test, while our Fluids and Offshore Services reporting units did not pass the first step. Maritech does not have any recorded goodwill. As described above, the second step of the goodwill impairment test uses the estimated fair value for the Fluids and Offshore Services reporting units as the purchase price in a hypothetical acquisition of the reporting unit. The allocation of this purchase price includes hypothetical adjustments to the carrying values of several asset carrying values for the Fluids and Offshore Services reporting units. After making these purc hase price allocation adjustments, there was no residual purchase price to be allocated to goodwill. Based on this analysis, we concluded that an impairment of the entire amount of recorded goodwill for our Fluids and Offshore Services reporting units was required, resulting in a charge to earnings of $47.1 million during the fourth quarter of 2008.

In March 2006, we acquired Beacon Resources, LLC (Beacon), a production testing operation, for approximately $15.6 million paid at closing. In addition, the acquisition agreement provided for additional contingent consideration of up to $19.1 million, depending on the average of Beacon’s annual pretax results of operations over the three year period following the closing date through March 2009. Based on Beacon’s annual pretax results of operations during this three year period, we paid $12.7 million in April 2009 to the sellers pursuant to this contingent consideration provision. This amount was charged to goodwill associated with the acquisition of Beacon.

In March 2006, we acquired the assets and operations of Epic Divers, Inc. and certain affiliated companies (Epic), a full service commercial diving operation. In June 2006, Epic purchased a dynamically positioned dive support vessel (the Epic Diver) and saturation diving unit. Pursuant to the Epic Asset Purchase Agreement, a portion of the net profits earned by this dive support vessel and saturation diving unit over the initial three year term following its purchase was to be paid to the sellers. Based on the vessel’s high utilization following the 2008 hurricanes, we paid $3.8 million in July 2009 pursuant to this contingent consideration provision. This amount was charged to goodwill associated with the acquisition of Epic.

Impairment of Long-Lived Assets

Impairments of long-lived assets are determined periodically when indicators of impairment are present. If such indicators are present, the determination of the amount of impairment is based on our judgments as to the future undiscounted operating cash flows to be generated from these assets throughout their remaining estimated useful lives. If these undiscounted cash flows are less than the carrying amount of the related asset, an impairment is recognized for the excess of the carrying value over its fair value. The assessment of oil and gas properties for impairment is based on the risk adjusted future estimated cash flows from our proved, probable, and possible reserves. Assets held for disposal are recorded at the lower of carrying value or estimated fair value less estimated selling costs.

Impairments of Oil and Gas Properties

During 2011, 2010, 2009, and 2008,2009, we identified impairments totaling approximately $15.2 million, $63.8 million, $11.4 million, and $42.7$11.4 million, respectively, net of intercompany eliminations, of the net carrying value of certain Maritech oil and gas properties. The oil and gas property impairments during 2011 were primarily associated
F-12

with Maritech’s plans to sell its remaining oil and gas producing properties and the reduction in their carrying values to fair value less cost to sell. The oil and gas property impairments during 2010 were mainly associated with Maritech’s non-core properties and were primarily due to significant increases in Maritech’s associated decommissioning liabilities for these properties. For further discussion of the adjustments to Maritech’s decommissioning liabilities during 2010, see Note I – Decommissioning and Other Asset Retirement Obligations. Additional oil and gas property impairments were also recorded during 2010 as a result of decreased production volumes, changes in development plans, or due to lower oil and natural gas pricing .pricing. The oil and gas property impairments during 2009 were primarily due to decreased production volumes or an increase in the associated decommissioning liabilities. The oil and gas property impairments during 2008 were primarily due to the impact of lower oil and natural gas pricing. In addition, certain properties were impaired as
F-12

a result of decreased production volumes and increases in the associated decommissioning liabilities, particularly as a result of the 2008 hurricanes.

Impairments of Other Long-Lived Assets

Due to the current market pricing for pellet calcium chloride and the uncertain supply of raw materials needed to operate our Fluids Division’s Lake Charles, Louisiana, calcium chloride plant on economic terms, expected operating cash flows of the plant are insufficient to cover the plant’s carrying value. Demand for pellet calcium chloride produced at the Lake Charles plant has been negatively affected by current market conditions. Accordingly, we recorded an impairment of approximately $7.2 million of the plant’s carrying value during the fourth quarter of 2010. In February, 2011, we shut down the pellet plant operation, although the liquid calcium chloride operation remains operational.

AlthoughDuring the Epic Diver, a dynamically positioned dive support vessel owned by our Epic Diving & Marine (Epic) subsidiary, has performed significantly since it was acquired in 2006,fourth quarter of 2010, our Offshore Services segment has determined that the vessel isEpic Diver was no longer strategic to its plans to serve its markets going forward. This decision was influenced by the recent extension of the charter of a modern dive support vessel that hashad been leased and utilized by Epic during the past year. This decision resulted in an impairment of the2010. The $15.3 million net carrying value of the Epic Diver by $15.3 million, which was recordedimpaired during the fourth quarter of 2010. In January 2011, the Offshore Services segment finalized its decision to divest the Epic Diver. The Offshore Services segment also identified certain additional, less significant, asset impairments during 2010.Diver, and the vessel was subsequently sold.

Our Fluids Division owns a 50% interestDuring 2009, in an unconsolidated joint venture whose assets consist primarilyresponse to the shutdown of a calcium chloride plant located in Europe. During 2009, theEurope that supplied raw materials to an unconsolidated joint venture, partner announced the shutdown of its adjacent plant facility, which supplies raw material to the calcium chloride plant. As a result, the joint venture’s calcium chloride plant was also shut down. During 2009, we reduced our investment in the joint venture to its estimated fair value based on the estimated plant decommissioning costs and salvage value cash flows of the joint venture, resulting in an impairment by our Fluids Division of our investment in the joint venture of $6.5 million.

During 2008, we identified impairments totaling approximately $8.7 million associated with a portion of the net carrying value of certain Offshore Services assets. Approximately $7.3 million of these impairments was as a result of decreased expected future cash flows from one of the segment’s barge vessels.

Decommissioning Liabilities

Related to our acquired interests inMaritech’s remaining oil and gas properties,property decommissioning liabilities, we estimate the third-party fair values (including an estimated profit) to plug and abandon wells, decommission the pipelines and platforms, and clear the sites, and we use these estimates to record Maritech’s decommissioning liabilities, net of amounts allocable to joint interest owners, anticipated insurance recoveries, and any amounts contractually agreed to be paid in the future by the previous owners of the properties. In some cases, previous owners of acquired oil and gas properties are contractually obligated to pay Maritech a fixed amount for the future well abandonment and decommissioning work on these properties as such work is performed. As of December 31, 20102011 and 2009,2010, our Maritech subsidiary’s decommissioning liabilities are net of approximately $32.5$7.0 million an d $43.6and $32.5 million, respectively, of such future reimbursements from these previous owners.

In estimating the decommissioning liabilities, we perform detailed estimating procedures, analysis, and engineering studies. Whenever practical and cost effective, Maritech will utilize the services of its affiliated companies to perform well abandonment and decommissioning work. When these services are performed by an affiliated company, all recorded intercompany revenues are eliminated in the consolidated financial statements. The recorded decommissioning liability associated with a specific property is fully extinguished when the property is completely abandoned. The liability is first reduced by all cash expenses incurred to abandon and decommission the property. If the liability exceeds (or is less than) our actual out-of-pocket costs, the difference is credited (or charged) to earnings in the period in which the work is performed. We review the adequacy of our decommissioning liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed materially. The timing and amounts of these cash flows are subject to changes in the energy industry environment and may result in additional liabilities to be recorded, which, in turn, would increase the carrying values of the related properties.properties or result in direct charges to earnings. As a result of decommissioning work performed, we recorded total reductions to the decommissioning liabilities for the years 2011, 2010, and 2009 of $94.7 million, $88.2 million, and $74.6 million, respectively. For a further discussion of adjustments and other activity related to Maritech’s

work performed, we recorded total reductions to the decommissioning liabilities for the years 2010, 2009, and 2008 of $88.2 million, $74.6 million, and $16.5 million, respectively. For a further discussion of adjustments and other activity related to Maritech’s decommissioning liabilities, including significant adjustments made during 2010 and 2011, see Note I – Decommissioning and Other Asset Retirement Obligations.

Environmental Liabilities

Environmental expenditures whichthat result in additions to property and equipment are capitalized, while other environmental expenditures are expensed. Environmental remediation liabilities are recorded on an undiscounted basis when environmental assessments or cleanups are probable and the costs can be reasonably estimated. Estimates of future environmental remediation expenditures often consist of a range of possible expenditure amounts, a portion of which may be in excess of amounts of liabilities recorded. In thissuch an instance, we disclose the full range of amounts reasonably possible of being incurred. Any changes or developments in environmental remediation efforts are accounted for and disclosed each quarter as they occur. Any recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed proba ble.probable.

Complexities involving environmental remediation efforts can cause the estimates of the associated liability to be imprecise. Factors whichthat cause uncertainties regarding the estimation of future expenditures include, but are not limited to, the effectiveness of the anticipated work plans in achieving targeted results and changes in the desired remediation methods and outcomes as prescribed by regulatory agencies. Uncertainties associated with environmental remediation contingencies are pervasive and often result in wide ranges of reasonably possible outcomes. Estimates developed in the early stages of remediation can vary significantly. Normally, a finite estimate of cost does not become fixed and determinable at a specific point in time. Rather, the costs associated with environmental remediation become estimable as the work is performed and the range of ultimate cost becomes more defined. It is possible that cash flows and results of operations could be materially affected by the impact of the ultimate resolution of these contingencies.

Revenue Recognition

Revenues are recognized when finished products are shipped or services have been provided to unaffiliated customers and only when collectability is reasonably assured. Sales terms for our products are FOB shipping point, with title transferring at the point of shipment. Revenue is recognized at the point of transfer of title. We recognize oil and gas product sales revenues from our Maritech subsidiary’s interests in producing wells as oil and gas is produced and sold from those wells. Oil and gas sold is not significantly different from Maritech’s share of production. With regard to turnkeylump-sum contracts, revenues are recognized using the percentage-of-completion method based on the ratio of costs incurred to total estimated costs at completion. Total project revenue and cost estimates for tu rnkeylump-sum contracts are reviewed periodically as work progresses, and adjustments are reflected in the period in which such estimates are revised. Provisions for estimated losses on such contracts are made in the period such losses are determined. For contracts that contain multiple deliverables, the recognition of revenue is determined based on the realized market values received by the customer as well as the timing of collections under the contract.

Oil and Gas Balancing

As part of our Maritech subsidiary’s acquisitions of producing properties, we have acquired oil and gas balancing receivables and payables related to certain properties. We allocate value for any acquired oil and gas balancing positions using estimated fair value amounts expected to be received or paid in the future. Amounts related to underproduced volume positions acquired are reflected as assets, and amounts related to overproduced volume positions acquired are reflected as liabilities. At December 31, 20102011 and 2009,2010, we reflected oil and gas balancing receivables of $2.6$1.0 million and $3.5$2.6 million, respectively, in accounts receivable and other long-term assets and oil and gas balancing payables of $5.4$2.6 million and $6.2$5.4 million, respectively, in accrued liabilities and other long-term liabilit ies.liabilities. We recognize oil and gas product sales from our Maritech subsidiary’s interest in producing wells, based on its entitled share of oil and natural gas produced and sold from those wells. Changes to our oil and gas balancing receivable or payable are valued at the lower of the price in effect at time of production, current market price, or contract price, if applicable.

Operating Costs

Cost of product sales includes direct and indirect costs of manufacturing and producing our products, including raw materials, fuel, utilities, labor, overhead, repairs and maintenance, materials, services, transportation, warehousing, equipment rentals, insurance, and taxes. In addition, cost of product sales
F-14

includes oil and gas operating expense. Cost of services and rentals includes operating expenses we incur in delivering our services, including labor, equipment rental, fuel, repair and maintenance, transportation, overhead, insurance, and certain taxes. We include in product sales revenues the reimbursements we receive from customers for shipping and handling costs. Shipping and handling costs are included in cost of product sales. Amounts we incur for “out-of-pocket” expenses in the delivery of our services are recorded as cost of services and rentals. Reimbursements for “out-of-pocket” expenses we incur in the delivery of our services are recorded as service revenues. Depreciation, depletion, amortization, and accretion includes depreciation expense for all of our facilities, equipment and vehicles, depletion and dry hole expense on our oil and gas properties, amortization expense on our intangible assets, and accretion expense related to our decommissioning and other asset retirement obligations.

We include in general and administrative expense all costs not identifiable to our specific product or service operations, including divisional and general corporate overhead, professional services, corporate office costs, sales and marketing expenses, insurance, and taxes.

Repair Costs and Insurance Recoveries

During 2008, weWe incurred significant damage to certain of our onshore and offshore operating equipment and facilities, primarily as a result of Hurricane Ike.Ike during 2008 and Hurricanes Katrina and Rita during 2005. Our Maritech subsidiary suffered varying levels of damage to the majority of its offshore oil and gas producing platforms and threeduring these storms, including the destruction of six of its offshore platforms and one of its inland water production facilities were destroyed. During 2005, as a result of Hurricanes Katrina and Rita, our Maritech subsidiary also suffered damage to the majority of its offshore oil and gas producing platforms, and three of its platforms and one of its inland water production facilities were also destroyed.

platforms. Hurricane damage repair efforts consist of the repair of damaged facilities and equipment, well intervention, abandonment, decommissioning, and debris removal associated with the destroyed offshore platforms, construction of replacement platforms and facilities, and redrilling of destroyed wells. The reconstruction of the two inland water production facilities has been completed, and four of the six platforms destroyed have been decommissioned. In addition, a majority of our damaged facilities and equipment, including our offshore platforms that were only partially damaged, have been repaired. Damage assessment costs and repair expenses up to the amount of insurance deductibles or not covered by insurance are charged to earnings as they are incurred. We recognized hurricane related repair expenses for the yearsyear ended December 31, 2009, and 2008 of $8.2 million and $8.5 million, respectively.million.

The estimated amountRemaining hurricane damage repair efforts consists primarily of future well intervention, abandonment,the decommissioning and debris removal costs were initially recorded in the period in which such damage occurred, net of expected insurance recoveries, as part of Maritech’s decommissioning liabilities. See further discussion of Maritech’s decommissioning liabilities in Decommissioning Liabilities section above. Through December 31, 2010, we have expended approximately $125.0 million for the well intervention, abandonment, decommissioning, debris removal, and platform reconstruction work performed on the destroyed platforms and production facilities. For certaintwo of the destroyed platforms, however, a significant amount of decommissioning and debris removal work remains to be completed. The majority of the well interventi on efforts to date have been performed by our Offshore Services segment.Maritech offshore platforms. We estimate that the remaining future abandonment, decommissioning, and debris removal and well redrill efforts associated with thethese remaining platforms destroyed by hurricanes during 2005 and 2008 will cost approximately $50 to $65$27.5  million net to our interest before any insurance recoveries. Approximately $28 to $39 million of this cost relates to platforms destroyed by Hurricane Ike in 2008. Approximately $38.1 million of our total future cost estimaterecoveries, and has been accrued as part of Maritech’s decommissioning liabilities. An additional amount of approximately $13 to $19 million relates primarily to the estimated cost to finalize a newly installed offshore platform at Maritech’s East Cameron 328 field and to complete the redrilling of several wells at this location. Actual hurricane repair costs could exceed these estimates and, depending on the nature of the cost, could result in significant charges to earnings in future periods. See below for a discussion of our remaining insurance coverage associated with hurricane damage repairs.

F-15 

WeWhen it is economical to purchase, we typically maintain insurance protection that we believe to be customary and in amounts sufficient to reimburse us for a majority of our casualty losses, including for a portion of the repair, well intervention, abandonment, decommissioning, and debris removal costs associated with the damages incurred from named windstorms and hurricanes. In addition, other damages such as the value of lost inventory and the cost to replace a sunken transport barge which was lost in 2009, are also covered by insurance. Our insurance coverage is subject to certain overall coverage limits and deductibles. For the Maritech hurricane damages caused by Hurricane Ike during 2008, we anticipate that those damages will exceed these overall coverage limits. With regard to costs incurred that we believe will qualify for coverage under our various insurance policies, we recognize anticipated insurance recoveries when collection is deemed probable. Any recognition of anticipated insurance recoveries is used to offset the original charge to which the insurance recovery relates. The amount of anticipated insurance recoveries as of December 31, 2011 and 2010, is either included in accounts receivable or recorded as an offset to Maritech’s decommissioning liabilities in the accompanying consolidated balance sheets.

The changes in anticipated insurance recoveries, including anticipated recoveries associated with the sunken barge and other non-hurricane related claims, during the most recent two year period are as follows:
  Year Ended December 31, 
  2010  2009 
  (In Thousands) 
       
Beginning balance $26,992  $33,591

   Insurance reimbursements  (26,238)  (27,176)
   Contested insurance recoveries  (583)  (651)
Ending balance at December 31 $541  $26,992 
During 2010, Maritech collected approximately $47.8 million of insurance proceeds associated with Hurricane Ike, which included the settlement of certain coverage at an amount less than the applicable coverage limits. For the $39.8 million of this amount that was collected in March 2010, the amount collected was greater than the covered hurricane repair, well intervention, and abandonment costs incurred as of that date, with the excess representing an advance payment of costs anticipated to be incurred in the future. The collection of these settlement proceeds havehas resulted in the extinguishment of all of Maritech’s insurance receivables, the reversal of the costs previously capitalized for the future decommissioning of oil and gas properties, the reversal of anticipated insurance recoveries that had been netted against certain decommissioni ngdecommissioning liabilities, and approximately $2.2 million of pre-tax insurance gains that were credited to
F-15

earnings during 2010. Maritech maintains that it has additional remaining coverage available relating to hurricane damage repairs of approximately $19.5 million, all of which relates to Hurricane Ike. During December 2010, we initiated legal proceedings against one of Maritech’s underwriters, that is disputing that certain costs incurred or to be incurred qualify as covered costs pursuant to the policies.

Maritech incurred certain well intervention, debris removal, and repair costs related to damage from Hurricanes Katrina and Rita which were not reimbursed by its insurers. In December 2007, Maritech filed a lawsuit against its insurers and other associated parties in an attempt to collect pursuant to the applicable policies. During the fourth quarter of 2009, Maritech entered into a settlement agreement under which it received approximately $40.0 million of the previously unreimbursed costs. We have reviewed the types of estimated well intervention costs incurred or to be incurred related to Hurricane Ike. Despite our belief that substantially all of these costs in excess of deductibles and within policy limits will qualify for coverage under our insurance policies, any costs that are similar to the costs that were not initially reimbursed followi ngfollowing Hurricanes Katrina and Rita have been excluded from anticipated insurance recoveries and were either capitalized to the associated oil and gas properties or expensed.

Anticipated insurance recoveries that have been reflected as a reductioninsurance receivables were $1.1 million as of our decommissioning liabilities were $0December 31, 2011, and $0.5 million at December 31, 2010, and $10.3 million at December 31, 2009. Anticipated insurance recoveries that have been reflected as insurance receivables were $0.5 million as of December 31,
F-16

2010, and $16.7 million at December 31, 2009. Uninsured assets that were destroyed during the storms are charged to earnings.2010. Repair costs incurred and the net book value of any destroyed assets which are covered under our insurance policies are anticipated insurance recoveries which are included in accounts receivable. Repair costs not considered probable of collection are charged to earnings. Insurance recoveries in excess of destroyed asset carrying values and repair costs incurred are credited to earnings when received. During 2010 2009, and 2008,2009, approximately $2.5 million $5.4 million, and $0.7$5.4 million, respectively, of such excess proceeds were credited to earnings.

Discontinued Operations

We have accounted for our discontinued businesses as discontinued operations and have reclassified prior period financial statements to exclude these businesses from continuing operations.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis amounts. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates is recognized as income or expense in the period that includes the enactment date.

Income (Loss) per Common Share

The calculation of basic earnings per share excludes any dilutive effects of options. The calculation of diluted earnings per share includes the dilutive effect of stock options, which is computed using the treasury stock method during the periods such options were outstanding. A reconciliation of the common shares used in the computations of income (loss) per common and common equivalent shares is presented in Note P – Income (Loss) Per Share.

 Foreign Currency Translation

We have designated the euro, the British pound, the Norwegian krone, the Canadian dollar, the Mexican peso,Brazilian real, and the Brazilian realMexican peso as the functional currency for our operations in Finland and Sweden, the United Kingdom, Norway, Canada, Mexico,Brazil, and Brazil,certain of our operations in Mexico, respectively. The U.S. dollar is the designated functional currency for all of our other foreign operations. The cumulative translation effects of translating the accounts from the functional currencies into the U.S. dollar at current exchange rates are included as a separate component of stockholders' equity.

Fair Value Measurements

Fair value is defined as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date” within an entity’s principal
F-16

market, if any. The principal market is the market in which the reporting entity would sell the asset or transfer the liability with the greatest volume and level of activity, regardless of whether it is the market in which the entity will ultimately transact for a particular asset or liability or if a different market is potentially more advantageous. Accordingly, this exit price concept may result in a fair value that may differ from the transaction price or market price of the asset or liability.

Under generally accepted accounting principles, the fair value hierarchy prioritizes inputs to valuation techniques used to measure fair value. Fair value measurements should maximize the use of observable inputs and minimize the use of unobservable inputs, where possible. Observable inputs are developed based on market data obtained from sources independent of the reporting entity. Unobservable inputs may be needed to measure fair value in situations where there is little or no market activity for the asset or liability at the measurement date and are developed based on the best information available in the circumstances, which could include the reporting entity’s own judgments about the assumptions market participants would utilize in pricing the asset or liability.

We utilize fair value measurements to account for certain items and account balances within our consolidated financial statements. Fair value measurements are utilized in the allocation of purchase consideration for acquisition transactions to the assets and liabilities acquired, including intangible assets and goodwill. In addition, we utilize fair value measurements in the initial recording of our decommissioning and other asset retirement obligations. Fair value measurements may also be utilized on a nonrecurring basis,
F-17

such as for the impairment of long-lived assets, including goodwill. The fair value of our financial instruments, which may include cash, temporary investments, accounts receivable, short-term borrowings, and long-term debt pursuant to our bank credit agreement, approximate their carrying amounts. The fair value of our long-term Senior Notes at December 31, 2011 and 2010 was approximately $332.4 million and $315.7 million, respectively, compared to a carrying amount of approximately $305.0 million, as current rates areas of those dates were more favorable than the Senior Note interest rates. We calculate the fair value of our Senior Notes internally, using current market conditions and average cost of debt. We have not calculated or disclosed recurringdebt (a level 2 fair value measurements of non-financial assets and non-financial liabilities.measurement).

We also utilize fair value measurements on a recurring basis in the accounting for our derivative contracts used to hedge a portion of our oil and natural gas production cash flows. For these fair value measurements, we compare forward oil and natural gas pricing data from published sources over the remaining derivative contract term to the contract swap price and calculate a fair value using market discount rates. During the second quarter of 2011, in connection with the sale of substantially all of our Maritech oil and gas producing properties, we liquidated our derivative contracts and paid $14.2 million to the counterparty. For further discussion, see Note O – Hedge Contracts. A summary of the fair value measurements for derivative contracts as of December 31, 2010, is as follows:

During 2011, Maritech recorded total impairment charges of approximately $15.2 million associated with its remaining oil and gas properties. During 2011, Maritech sold approximately 95% of its oil and gas reserves and is seeking to sell its remaining properties at current market values. Accordingly, all of Maritech’s remaining oil and gas properties as of December 31, 2011, have been reclassified to oil and gas properties held for sale and their net book values have been adjusted to fair value less cost to sell. Fair values are estimated based on current market prices being received for these properties’ expected future production cash flows, using forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

During 2010, certain Maritech oil and gas property impairments of $63.8 million were charged to earnings. The majority of the oil and gas property impairments for 2010 were due to increased estimates of Maritech’s decommissioning liabilities. For a portion of these impaired properties, however, the change in the fair value of the properties was due to decreased expected future cash flows based on forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy. Also during 2010, our Offshore Services segment recorded impairments for certain equipment assets, including the Epic Diver. In addition, our Fluids segment recorded an impairment for its Lake Charles, Louisiana, calcium chloride plant. The fair values of these assets were based on their resale value based on purchase offers received or their estimated salvage values.

During 2009, certain Maritech oil and gas property impairments of $11.4 million were charged to earnings. For a portion of these impaired properties, the change in the fair value of the properties was due to decreased expected future cash flows based on forward oil and natural gas pricing data from published sources. Because such published forward pricing data was applied to estimated oil and gas reserve volumes based on our internally prepared reserve estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accordance with the fair value hierarchy.

Our Fluids Division owns a 50% interest in an unconsolidated joint venture whose assets consist primarily of a calcium chloride plant located in Europe. During 2009, the joint venture partner announced the shutdown of its adjacent plant facility, which supplies raw material to the calcium chloride plant. As a result, the joint venture’s calcium chloride plant was also shut down. During the second quarter 2009, we reduced our investment in the joint venture to its estimated fair value based on the estimated plant decommissioning costs and salvage value cash flows of the joint venture, resulting in an impairment of our investment in the joint venture of $6.5 million. Because the investment fair value was determined based on internally prepared estimates, such fair value calculation is based on significant unobservable inputs (Level 3) in accor dance with the fair value hierarchy.

New Accounting Pronouncements

In October 2009,September 2011, the Financial Accounting Standards Board (FASB) published Accounting Standards Update (ASU) 2009-13, “Revenue Recognition2011-08, “Intangibles – Goodwill and Other (Topic 605)350), Multiple Deliverable Revenue Arrangements,”Testing Goodwill for Impairment” (ASU 2011-08), which establishessimplifies how entities test goodwill for impairment. The amendments in ASU 2011-08 permit an entity to first assess qualitative factors to determine whether it is more likely than not that the accounting andfair value of a reporting guidanceunit is less than its carrying amount as a basis for arrangements under which service providers willdetermining whether it is necessary to perform multiple revenue-generating activities. Specifically, this guidance addresses how to separate deliverables and how to measure and allocate arrangement consideration to one or more units of accounting. Additional disclosures of multiple deliverable arrangements will also be required.the two-step goodwill impairment test described in Topic 350. The ASU 2009-13 is effective prospectively for revenue arrangements entered into or materially modified inannual and interim goodwill impairment tests performed for fiscal years beginning on or after JuneDecember 15, 2010.2011. Early adoption is permitted. The adoption of ASU 2011-08 did not have a significant impact on our financial statements.
F-18

In June 2011, the FASB published ASU 2011-05, “Comprehensive Income (Topic 220), Presentation of Comprehensive Income” (ASU 2011-05), which has the objective of improving the comparability, consistency, and transparency of financial reporting and increasing the prominence of items reported in other comprehensive income. As part of ASU 2011-05, the FASB decided to eliminate the option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity, among other amendments in this ASU. The amendments require that all non-owner changes in stockholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The amendments in this ASU are to be effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, and the amendments are to be applied retrospectively. In December 2011, with the issuance of ASU 2011-12, “Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05,” the FASB announced that it has deferred certain aspects of ASU 2011-05. The adoption of the accounting and disclosure requirements of this AS UASU is not expected to have a significant impact on our financial statements.

In May 2011, the FASB published ASU 2011-04, “Fair Value Measurement (Topic 820) – Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs,” whereby the FASB and the International Accounting Standards Board (IASB) aligned their definitions of fair value such that their fair value measurement and disclosure requirements are the same (except for minor differences in wording and style). The Boards concluded that the amendments in this ASU will improve the comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with U.S. GAAP and IFRS. The amendments in this ASU are effective during interim and annual periods beginning after December 15, 2011, and are to be applied prospectively. The adoption of the accounting and disclosure requirements of this ASU will not have a significant impact on our financial statements.

In January 2010, the FASB published ASU 2010-06, “Fair Value Measurements and Disclosures (Topic 820), Improving Disclosures about Fair Value Measurements,” which requires new disclosures about transfers in and out of fair value hierarchy levels, requires more detailed disclosures about activity in Level 3 fair value measurements and clarifies existing disclosure requirements about asset and liability aggregation, inputs, and valuation techniques. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosure requirements of activity in Level 3 fair value measurements, which become effective for fiscal years beginning after December 15, 2010, and for interim periods within those fiscal years. The adoption of the disclosur e requirements of this ASU did not have a significant impact on our financial statements, and the disclosure requirements of activity in Level 3 fair value measurements will not have a significant impact on our financial statements.

NOTE C — DISCONTINUED OPERATIONSCOMPRESSCO PARTNERS, L.P. INITIAL PUBLIC OFFERING

DuringOn June 20, 2011, our Compressco Partners, L.P. (Compressco Partners) subsidiary completed its initial public offering of 2,670,000 common units (representing a 17.3% limited partner interest) in exchange for $53.4 million of gross proceeds (the Offering). Following the fourth quarterissuance of 2007, we disposedan additional 400,500 units to us in July 2011 as a result of the expiration of an underwriters’ option to purchase additional common units, our ownership in Compressco Partners has been increased to 83.2%, including common units, subordinated units, and a 2% general partner interest. In connection with the Offering, certain of our process serviceswholly owned subsidiaries, including Compressco Partners GP Inc. (the General Partner), contributed substantially all of our Compressco segment’s wellhead compression-based production enhancement service business, operations, throughand related assets and liabilities to Compressco Partners and its wholly owned subsidiaries. In exchange, including the additional units issued in July 2011, Compressco Partners issued to us 6,427,257 common units (representing a sale40.6% limited partner interest), 6,273,970 subordinated units (representing a 39.6% limited partner interests), an aggregate 2.0% general partner interest, and incentive distribution rights. Also, certain directors, executive officers, and other employees of the associatedGeneral Partner were then issued 157,870 restricted units (representing a 1.0% limited partner interest) granted pursuant to a long-term incentive plan. The issuance of the 2,670,000 common units in the Offering at a $20 per unit Offering Price resulted in Compressco Partners receiving $53.4 million of gross proceeds, $32.2 million of which was distributed to us to repay an intercompany loan balance. Approximately $11.2 million of the Offering proceeds was used to satisfy Offering expenses, including underwriters’ discount and approximately $8.0 million that was paid to us by Compressco Partners to reimburse us for costs we incurred on their behalf. The contribution transactions described above represent transactions between entities under common control. Consequently, the contributed assets were recorded at our carrying value.

The contributions of the majority of the operations and related assets and operationsliabilities of our Compressco segment were effected pursuant to the terms of a Contribution, Conveyance and Assumption Agreement (the Contribution Agreement). Compressco Partners is governed by the First Amended and Restated Agreement of Limited Partnership (the Partnership Agreement). The Partnership Agreement requires Compressco Partners to distribute all of its available cash, as defined in the Partnership Agreement, to the holders of the common units, subordinated units, 2% general partner interest, and incentive distribution rights in accordance with the terms of the Partnership Agreement. The Partnership Agreement also provides for total cash proceedsthe management of approximately $58.9 million. Our process services operation providedCompressco Partners by the technologyGeneral Partner. The reimbursement of direct and indirect costs incurred by us in providing personnel and services requiredon behalf of Compressco Partners, as well as other transactions between us and Compressco Partners, is governed by the terms of an Omnibus Agreement between us and Compressco Partners.

During the fourth quarter of 2006, we made the decision to dispose of our fluids and production testing operations in Venezuela due to several factors including the country’s changing political climate. Our Venezuelan fluids operation was previously part of our Fluids Division, and the production testing operation was previously part of our Production Enhancement Division.

NOTE D — ACQUISITIONS AND DISPOSITIONS

On July 20, 2011, we purchased a new heavy lift derrick barge (which we have named the TETRA Hedron) with a 1,600-metric-ton lift capacity, fully revolving crane. The vessel was purchased from Wison (Nantong) Heavy Industry Co., Ltd. and Nantong MLC Tongbao Shipbuilding Co., Ltd. for $62.8 million. Approximately $20.8 million of the purchase price was initially held in certain escrow accounts and the remaining escrow amount is to be released in accordance with the terms of the escrow agreements. The amount of remaining cash in escrow will be included in restricted cash on our consolidated balance sheet until the final release of escrow cash on April 30, 2014. The vessel was transported to the Gulf of Mexico during the third quarter and was placed into service during the fourth quarter of 2011 following final outfitting and sea trials.

In March 2011, we acquired a project management and engineering consulting services business that provides liability and risk assessment services for domestic and international offshore well abandonment and decommissioning projects. The purchase price for this acquisition was $1.5 million and the assets acquired consist primarily of intangible assets.

In late 2010, we began to decrease our investment in Maritech by suspending oil and gas property acquisitions, decreasing our development activities, exploring strategic alternatives to our ownership of Maritech and its oil and gas properties, and reviewing opportunities to sell Maritech oil and gas property packages. As part of this overall effort, in February and March 2011, Maritech sold certain properties, along with the associated decommissioning liabilities. As part of these transactions, Maritech paid an aggregate of approximately $2.8 million at closing after normal purchase price adjustments. These sold properties, in the aggregate, accounted for approximately 12% of Maritech’s proved reserves as of December 31, 2010.

On May 31, 2011, Maritech completed the sale of approximately 79% of its proved oil and gas reserves as of December 31, 2010, to Tana Exploration Company LLC (Tana), a subsidiary of TRT Holdings, Inc. (TRT), pursuant to a Purchase and Sale Agreement dated April 1, 2011. The sale was made to Tana for a base purchase price of $222.3 million. At the closing of the sale, Tana assumed approximately $72.7 million of associated asset retirement obligations, and Maritech received $173.3 million cash at closing, representing the base purchase price less $11.1 million that consisted of a deposit that was paid in April 2011 and purchase price adjustments, including those adjustments reflecting cash flows subsequent to the January 1, 2011, effective date. The proceeds were subject to additional post-closing adjustments. As a result of the sale, we recorded a consolidated gain on sale of assets of $56.8 million. Due to Maritech’s continuing efforts to sell its remaining oil and gas properties, such properties have been reclassified to oil and gas properties held for sale, and their net book values have been adjusted to fair value, less cost to dispose. In connection with the sale of Maritech oil and gas producing properties, during the second quarter of 2011, we charged to general and administrative expenses approximately $2.7 million of employee retention and incentive benefits paid in connection with these sales.
F-20

In August 2011, Maritech sold an additional remaining oil and gas property in exchange for the purchaser assuming the associated decommissioning liability. The sold property represents approximately 3% of Maritech’s December 31, 2010, oil and gas reserves.

In December 2010, our Offshore Services segment acquired certain well abandonment and wireline assets and operations from ProServ Offshore, Inc. pursuant to an asset purchase agreement. As consideration for the acquired assets, we paid approximately $6.3 million of cash at closing. We allocated the purchase price of this acquisition to the fair value of the assets and liabilities acquired, which consisted of approximately $6.4 million of property, plant, and equipment; $0.6 million of certain intangible assets; and $0.7 million of current liabilities. Intangible assets are amortized over their estimated useful lives, ranging from three to six years.

In July 2010, our Maritech subsidiary purchased interests in certain onshore oil and gas properties located in McMullen County, Texas, from Texoz E&P Holding, Inc. The acquired properties were recorded at a cost of approximately $6.7 million.

In late 2010, we began to decrease our investment in Maritech by suspending our search for oil and gas property acquisitions and decreasing our development activities. In addition, we are exploring strategic alternatives to our ownership of Maritech and its oil and gas properties and we are reviewing opportunities to
F-20

sell Maritech oil and gas property packages to industry participants and other third parties. As part of this overall effort, in February 2011, Maritech sold a group of properties that accounted for approximately 11.4% of its proved reserves.
During 2009, our Maritech subsidiary sold interests in certain oil and gas properties in two separate transactions. As a result of these transactions, the buyers of the properties assumed an aggregate of approximately $6.3 million of Maritech’s associated decommissioning liabilities. Maritech received cash of approximately $4.2 million as a result of these sale transactions and recognized gains totaling approximately $7.3 million. The amount of oil and gas reserve volumes associated with the sold properties was immaterial.

In January 2008, our Maritech subsidiary acquired oil and gas producing properties located in the offshore Gulf of Mexico from Stone Energy Corporation in exchange for the assumption of the associated decommissioning liabilities with a fair value of approximately $19.9 million. In addition, we paid $13.7 million of cash, $2.3 million of which had been paid on deposit in November 2007. The acquired properties were recorded at their cost of approximately $33.6 million.

During the third quarter of 2008, Maritech sold certain oil and gas properties and assets in which the buyers assumed an aggregate of approximately $4.7 million of Maritech’s associated decommissioning liabilities. Maritech retained a decommissioning obligation of approximately $0.2 million in these transactions and recognized gains totaling approximately $4.5 million. The amount of oil and gas reserve volumes associated with the sold properties was immaterial.

All of our acquisitions have been accounted for as purchases, with operations of the companies and businesses acquired included in the accompanying consolidated financial statements from their respective dates of acquisition. The purchase price has been allocated to the acquired assets and liabilities based on a determination of their respective fair values. The excess of the purchase price over the fair value of the net assets acquired is included in goodwill and assessed for impairment annually or whenever indicators are present. We have not recorded any goodwill in conjunction with our oil and gas property acquisitions.

NOTE E — LEASES

We lease some of our transportation equipment, office space, warehouse space, operating locations, and machinery and equipment. Certain facility storage tanks being constructed are leased pursuant to a ten year term, which is classified as a capital lease. The office, warehouse, and operating location leases, which vary from one to twenty-five year terms that expire at various dates through 2017 and are renewable for three and five year periods on similar terms, are classified as operating leases. Transportation equipment leases expire at various dates through 2016 and are also classified as operating leases. The office, warehouse, and operating location leases, and machinery and equipment leases generally require us to pay all maintenance and insurance costs.

Future minimum lease payments by year and in the aggregate, under non-cancelable capital and operating leases with terms of one year or more, consist of the following at December 31, 2010:2011:

We recognize interest and penalties related to uncertain tax positions in income tax expense. During the years ended December 31, 2011, 2010, 2009, and 2008,2009, we credited $0.3 million, $0.2 million, $0.5 million, and $0.3$0.5 million, respectively, for the net reversal of previously recorded interest and penalties to the provision for income tax. As of December 31, 20102011 and 2009,2010, we had $1.8$1.5 million and $2.0$1.8 million, respectively, of accrued potential interest and penalties associated with these uncertain tax positions. The total amount of unrecognized tax benefits that would affect our effective tax rate if recognized is $1.4$1.1 million and $1.7$1.4 million as of December 31, 20102011 and 2009,2010, respectively. We do not expect a significant change to the unrecognized tax benefits during the next twelve months.

We file tax returns in the U.S. and in various state, local, and non-U.S. jurisdictions. The following table summarizes the earliest tax years that remain subject to examination by taxing authorities in any major jurisdiction in which we operate:

JurisdictionEarliest Open Tax Period
United States – Federal2008
United States – State and Local2002
Non-U.S. jurisdictions20042005

We use the liability method for reporting income taxes, under which current and deferred tax assets and liabilities are recorded in accordance with enacted tax laws and rates. Under this method, at the end of each period, the amounts of deferred tax assets and liabilities are determined using the tax rate expected to be in effect when the taxes are actually paid or recovered. We will establish a valuation allowance to reduce the deferred tax assets when it is more likely than not that some portion or all of the deferred tax assets will not be realized. While we have considered future taxable income and ongoing tax planning strategies in assessing the need for the valuation allowance, there can be no guarantee that we will be able to realize all of our deferred tax assets. Significant components of our deferred tax assets and liabilities as of Dece mberDecember 31, 20102011 and 20092010, are as follows:

The change in the valuation allowance during 20102011 primarily relates to an increasethe state tax effects of state operating loss carryforwards.restructuring certain subsidiaries. We believe the ability to generate sufficient taxable income may not allow us to realize all the tax benefits of the deferred tax assets within the allowable carryforward period. Therefore, an appropriate valuation allowance has been provided.

At December 31, 2010,2011, we had approximately $5.5$8.3 million of foreign and state net operating loss carryforwards. In those countries and states in which net operating losses are subject to an expiration period, our loss carryforwards, if not utilized, will expire at various dates from 20112012 through 2030.2031. At December 31, 2010,2011, we had $3.6$4.2 million of foreign tax credits available to offset future payment of federal income taxes. The foreign tax credits expire in varying amounts from 2015 through 2020.2021.

Bank Credit Facilities

Our Bank Credit Facility

On October 29, 2010, we amended our existing bank revolving credit facility agreement with a syndicationsyndicate of banks, whereby the credit facility was decreased from $300 million to $278 million and its scheduled maturity was extended from June 2011 to October 2015. In addition, the amended credit facility agreement (the Credit Agreement) allows us to increase the facility by $150 million up to a $428 million limit upon the agreement of the lenders and the satisfaction of certain conditions. As of December 31, 2010,2011, we did not have any outstanding balance on the amended revolving credit facility, andalthough we had $13.4$8.0 million in letters of credit and guarantees against the $278.0 million availability under the amended revolving credit facility, leaving a net availability of $264.6$270 million.

Under the amended credit facility agreement (the Credit Agreement),Agreement, which matures on October 20, 2015, the revolving credit facility which is scheduled to mature in October 2015, remains unsecured and guaranteed by certain of our material U.S. subsidiaries.subsidiaries (excluding Compressco). Borrowings generally bear interest at the British Bankers Association LIBOR rate plus 1.5% to 2.5%, depending on one of our financial ratios. We pay a commitment fee ranging from 0.225% to 0.500% on unused portions of the facility. Similar to the previous terms, theThe Credit Agreement contains customary covenants and other restrictions, including certain financial ratio covenants involving our levels of debt and interest cost compared to a defined measure of our operating cash flows over a twelve month period. In addition, the Credit Agreement includes limitations on aggregate asset sales, individual acquisitions, and aggregate a nnualannual acquisitions and capital expenditures. Access to our revolving credit line is dependent upon our ability to comply with the certain financial ratio covenants set forth in the Credit Agreement, as discussed
F-25

above. Significant deterioration of the financial ratios could result in a default under the Credit Agreement and, if not remedied, could result in termination of the agreementCredit Agreement and acceleration of any outstanding balances. In June 2011, associated with the contribution of the majority of the operations and related assets and liabilities of our Compressco segment into Compressco Partners, Compressco Partners was designated as an unrestricted subsidiary and is no longer a borrower or a guarantor under our bank credit facility.

The Credit Agreement also includes cross-default provisions relating to any other indebtedness greater than a defined amount. If any such indebtedness is not paid or is accelerated and such event is not remedied in a timely manner, a default will occur under the Credit Agreement. Our Credit Agreement also contains a covenant that restricts us from paying dividends in the event of a default or if such payment would result in an event of default. We are in compliance with all covenants and conditions of our Credit Agreement as of December 31, 2010.2011. Our continuing ability to comply with these financial covenants centersdepends largely upon our ability to generate adequate cash flow. Historically, our financial performance has been more than adequate to meet these covenants, and we expect this trend to continue.

Our European Credit Agreement

We also have a bank line of credit agreement covering the day to day working capital needs of certain of our European operations (the European Credit Agreement). The European Credit Agreement provides for available borrowing capacity of up to 5 million euros (approximately $6.7$6.5 million equivalent as of December
F-25

31, 2010)2011), with interest computed on any outstanding borrowings at a rate equal to the lender’s Basis Rate plus 0.75%. The European Credit Agreement is cancellable by either party with 14 business days notice and contains standard provisions in the event of default. As of December 31, 2010,2011, we had no borrowings pursuant to the European Credit Agreement.

Compressco Partners’ Bank Credit Facility

On June 24, 2011, Compressco Partners entered into a new credit agreement (the Partnership Credit Agreement) with JPMorgan Chase Bank, N.A. Under the Partnership Credit Agreement, Compressco Partners, along with certain of its subsidiaries, are named as borrowers, and all of its existing and future, direct and indirect, domestic subsidiaries are guarantors. We are not a borrower or a guarantor under the Partnership Credit Agreement. The Partnership Credit Agreement includes borrowing capacity of $20.0 million (less $3.0 million that is required to be set aside as a reserve that cannot be borrowed) that is available for letters of credit (with a sublimit of $5.0 million) and an uncommitted $20.0 million expansion feature. The Partnership Credit Agreement may be used to fund Compressco Partners’ working capital needs, letters of credit, and for general partnership purposes, including capital expenditures and potential future acquisitions. So long as Compressco Partners is not in default, the Partnership Credit Agreement could also be used to fund Compressco Partners’ quarterly distributions. Borrowings under the Partnership Credit Agreement are subject to the satisfaction of customary conditions, including the absence of a default. As of December 31, 2011, there is no balance outstanding under the Partnership Credit Agreement. The maturity date of the Partnership Credit Agreement is June 24, 2015.

All obligations under the Partnership Credit Agreement and the guarantees of those obligations are secured, subject to certain exceptions, by a first lien security interest in substantially all of the assets (excluding real property) of Compressco Partners and its existing and future, direct and indirect domestic subsidiaries, and all of the capital stock of its existing and future, direct and indirect subsidiaries (limited, in the case of foreign subsidiaries, to 65% of the capital stock of first tier foreign subsidiaries).

Borrowings under the Partnership Credit Agreement bear interest at a rate per annum equal to, at Compressco Partners’ option, either (a) LIBOR (adjusted to reflect any required bank reserves) for an interest period equal to one, two, three, or six months (as we select), plus a margin of 2.25% per annum or (b) a base rate determined by reference to the highest of (1) the prime rate of interest announced from time to time by JPMorgan Chase Bank, N.A. or (2) LIBOR (adjusted to reflect any required bank reserves) for a one-month interest period on such day, plus 2.50% per annum. In addition to paying interest on any outstanding principal under the Partnership Credit Agreement, Compressco Partners is required to pay customary collateral monitoring fees and letter of credit fees, including, without limitation, a letter of credit fee equal to the applicable margin on revolving credit LIBOR loans and fronting fees.

The Partnership Credit Agreement requires Compressco Partners to maintain a minimum interest coverage ratio (ratio of earnings before interest and taxes to interest) of 2.5 to 1.0 as of the last day of any fiscal quarter, calculated on a trailing four quarter basis, whenever availability is less than $5 million. In addition, the Partnership Credit Agreement includes customary negative covenants, which, among other things, limit Compressco Partners’ ability to incur additional debt, incur, or permit certain liens to exist, or make certain loans, investments, acquisitions, or other restricted payments. The Partnership Credit Agreement provides that Compressco Partners can make distributions to holders of its common and subordinated units, but only if there is no default or event of default under the facility. If an event of default occurs, the lenders are entitled to take various actions, including the acceleration of amounts due under the Partnership Credit Agreement and all actions permitted to be taken by secured creditors.

Senior Notes

Each of our issuances of senior notes (collectively, the Senior Notes) are governed by the terms of the Master Note Purchase Agreement dated September 2004, as supplemented, the Note Purchase Agreement dated April 2008, or the Master Note Purchase Agreement dated September 23, 2010, (collectively, the Note Purchase Agreements). We may prepay the Senior Notes, in whole or in part, at any time at a price equal to 100% of the principal amount outstanding, plus accrued and unpaid interest and a “make-whole” prepayment premium. The Senior Notes are unsecured and are guaranteed by substantially all of our wholly owned U.S. subsidiaries. The Note Purchase Agreements, as supplemented, contain customary covenants and restrictions, require us to maintain certain financial ratios, and contain customary default
F-26

provisions, as well as a cross-defaul tcross-default provision relating to any other of our indebtedness of $20 million or more. We are in compliance with all covenants and conditions of the Note Purchase Agreements as of December 31, 2010.2011. Upon the occurrence and during the continuation of an event of default under the Note Purchase Agreements, the Senior Notes may become immediately due and payable, either automatically or by declaration of holders of more than 50% in principal amount of the Senior Notes outstanding at the time.

In SeptemberDecember 2010, we entered into an agreement whereby we agreed to issueissued and sellsold through a private placement $65.0 million in aggregate principal amount of Series 2010-A Senior Notes and $25.0 million in aggregate principal amount of Series 2010-B Senior Notes (collectively, the 2010 Senior Notes), pursuant to a Note Purchase Agreement dated September 30, 2010. In December 2010, partially funded by the $90 million proceeds from the 2010 Senior Notes, we paid $95.7 million to repay the Series 2004 Senior Notes, including principal, accrued interest, and a $2.8 million “make whole” prepayment premium which was charged to other expense.

Pursuant to the Note Purchase Agreements, the Series 2010-A Senior Notes bear interest at the fixed rate of 5.09% and mature on December 15, 2017. The Series 2010-B Senior Notes bear interest at the fixed rate of 5.67% and mature on December 15, 2020. Interest on the 2010 Senior Notes is due semiannually on June 15 and December 15 of each year. The Senior Notes were sold in the United States to accredited investors pursuant to an exemption from the Securities Act of 1933.

NOTE I — DECOMMISSIONING AND OTHER ASSET RETIREMENT OBLIGATIONS

The large majority of our asset retirement obligations consists of the future well abandonment and decommissioning costs for offshore oil and gas propertiesfacilities and platforms owned by our Maritech subsidiary.subsidiary, including the remaining abandonment, decommissioning, and debris removal costs associated with offshore platforms destroyed by hurricanes. The amount of decommissioning liabilities recorded by Maritech is reduced by amounts allocable to joint interest owners anticipated insurance recoveries, and any contractual amount to be paid by the previous owner of the oil and gas property when the liabilities are satisfied. We also operate facilities in various U.S. and foreign locations that are used in the manufacture, storage, and sale of our products, inventories, and equipment, including offshore oil and gas production facilities and equipment. These facilities are a combination of owned and leased assets. We are required to take certain actions in connection with the retirement of these assets. We have reviewed our obligations in this regard in detail and estimated the cost of these actions. These estimates are the fair values that have been recorded for retiring these long-lived assets. The associated asset retirement costs are capitalized as part of the carrying amount of the long-lived asset. The costs for non-oil and gas assets are depreciated on a straight-line basis over the life of the asset for non-oil and gas assets and on a unit of production basis for oil and gas properties.asset.

The changes in the asset retirement obligations during the most recent two year period are as follows:

Ending balance at December 31 $272,815  $224,110 
Ending balance $139,835  $272,815 
 
We review the adequacy of our decommissioning liabilities whenever indicators suggest that the estimated cash flows underlying the liabilities have changed materially. For our Maritech segment, the timing and amounts of these cash flows are subject to changes in the energy industry environment and other factors and may result in additional liabilities to be recorded. During 2011, we increased the estimated cash flows to decommission these properties by approximately $80.2 million, which resulted in approximately $78.4 million of direct charges to expense during the year. These increased estimates are included in the revisions in estimated cash flows in the table above. A large portion of the excess decommissioning costs recorded during 2011 was associated with properties not operated by Maritech. Specific factors that caused Maritech’s decommissioning liabilities to increase during 2011 included:
F-27

·  certain properties that had been previously abandoned required additional work to relieve pressure on wells and to remove structural debris not previously known;
·  due to our continued extensive abandonment program begun in prior years, we were able to further refine our estimates for certain properties with similar characteristics and risk profiles to those recently abandoned; and
·  two platforms destroyed by hurricanes during 2005 were found to be more extensively damaged than previously estimated, which caused us to add additional costs for removing these downed structures.

Our estimate of remaining hurricane related decommissioning costs is approximately $27.5 million and has been accrued as part of Maritech’s decommissioning liabilities. Settlements of asset retirement obligations during 2011 include approximately $122.0 million of obligations associated with oil and gas properties that were sold by Maritech during the year.

In September 2010, the Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) provided in a Notice to Lessees No. 2010-G05 (NTL 2010-G05) rules for the plugging and abandonment of wells and decommissioning of associated platforms and facilities. NTL 2010-G05 provides specific guidelines for the maximum time that an operator has to permanently plug wells and decommission platforms and facilities upon occurrence of certain events, including the end of useful operations, cessation of commercial production, and expiration of leases.leases. As of December 31, 2010, Maritech identified significant adjustments to be made to increase its decommissioning liabilities to reflect current industry developments, including the impact from these NTL 2010-G05 “Idle Iron Guidance” regulations. The adjustments made during 2010 resulted in $54.0 million of direct charges to operating expense, and the remainder was charged to the associated properties and partly contributed to asset impairments during the year. Specific factors causing Maritech’s decommissioning liabilities to increase significantly include:
·  Maritech received a letter from BOEMRE in October 2010 that identifies certain of its wells and platforms that are required to be abandoned or decommissioned in accordance with the NTL 2010-G05 regulations. As a result, it will be necessary to perform the abandonment and decommissioning of these properties on an accelerated basis, thus increasing the discounted fair value of the associated decommissioning liabilities;
·  Maritech believes that its ability to obtain permits for reefing abandoned platforms and facilities in place will now be significantly diminished and, accordingly, it has increased its cost estimates to reflect the incremental costs of transportation to shore;
·  Following the Macondo oil spill in 2010, Maritech’s well abandonment cost estimates have been increased to add additional costs for surveying, planning, executing, and supervising abandonment activities in a manner that ensures maximum protection for the environment and personnel engaged in the operations;
F-27

·  Our decision to decrease Maritech’s development activities has resulted in the acceleration of certain planned abandonment and decommissioning work compared to previous estimates, thus increasing the discounted fair value of the decommissioning liabilities;
·  Our extensive abandonment program of the last year has caused us to revise and refine certain of our estimates, particularly those relating to the cost of final site clearance and cleanup; and
·  We believe that a significant increase in the cost of contracted services will result from the increased regulatory requirements. A significant increase in demand for abandonment and decommissioning services is expected during the next several years, when the majority of Maritech’s work is currently planned to be performed due to the age of its properties.

Maritech’s decommissioning liabilities also include the remaining future well intervention, abandonment, decommissioning, and debris removal efforts associated with the platforms destroyed by hurricanes during 2005 and 2008. During 2010 and 2009, we increased the estimated cash flows to decommission these properties by approximately $29.3 million and $17.9 million, respectively. These increased estimates are included in the revisions in estimated cash flows in the table above. Our estimate of hurricane related decommissioning costs is approximately $38.1 million and has been accrued as part of Maritech’s decommissioning liabilities.

NOTE J — COMMITMENTS AND CONTINGENCIES

Litigation

We are named defendants in several lawsuits and respondents in certain governmental proceedings arising in the ordinary course of business. While the outcome of lawsuits or other proceedings against us cannot be predicted with certainty, management does not reasonably expect these matters to have a material adverse impact on the financial statements.

Class Action Lawsuit

Between March 27, 2008, and April 30, 2008, two putative class action complaints were filed in the United States District Court for the Southern District of Texas (Houston Division) against us and certain former officers by certain stockholders on behalf of themselves and other stockholders who purchased our common stock between January 3, 2007, and October 16, 2007. The complaints assert claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On May 8, 2008, the Court consolidated these complaints as In re TETRA Technologies, Inc. Securities Litigation, No. 4:08-cv-0965 (S.D. Tex.). On June 16, 2010, defendants and plaintiff’s counsel reached a settlement agreement whereby all claims against defendants will be re leased in exchange for a payment of $8.25 million, which was subsequently paid by our insurers. On September 29, 2010, the Court approved the settlement and entered the Order and Final Judgment terminating the class action lawsuit.

Derivative Lawsuit

Between May 28, 2008 and June 27, 2008, two petitions were filed by alleged stockholders in the District Courts of Harris County, Texas, 133rd and 113th Judicial Districts, purportedly on our behalf. The suits name our directors and certain officers as defendants. The factual allegations in these lawsuits mirror those in thea federal class action lawsuit and thewhich was settled during 2010. The claims are for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petitions seek disgorgement, costs, expenses, and unspecified equitable relief. On September 22, 2008, the 133rd District Court cons olidatedconsolidated these complaints as In re TETRA Technologies, Inc. Derivative Litigation, Cause No. 2008-23432 (133rd Dist. Ct., Harris County, Tex.), and appointed Thomas Prow and Mark Patricola as Co-Lead Plaintiffs. This lawsuit was stayed by agreement of the parties pending the Court’s ruling on our motion to dismiss the federal class action. On September 8, 2009, the plaintiffs in this state court action filed a consolidated petition which makes factual allegations similar to the surviving allegations in the federal lawsuit.lawsuit prior to it being settled. On April 19, 2010, the Court granted our motion to abate the suit, based on plaintiff’s inability to demonstrate derivative standing. On June 8, 2010, we received a letter from plaintiff’s counsel demanding that our board of directors take action against the defendants named in the previously filed derivative lawsuit. Our board is current ly evaluatingOn August 22, 2011, the best courseCourt issued a Preliminary Approval Order preliminarily approving the settlement of actionthe suit as set forth in the Stipulation of Settlement dated August 12, 2011 (the Stipulation). The Stipulation does not provide for the payment of monetary compensation to take in responsestockholders; rather, it provides for certain additions to our corporate governance policies and procedures and for the demand letter.payment of plaintiff’s attorneys’ fees and litigation expenses, which have been paid by our insurers. On October 17, 2011, the Court granted final approval of the settlement.

 
F-28

 
At this stage, it is impossible to predict the outcome of these proceedings or their impact upon us. We currently believe that the allegations made in the federal complaints and state petitions are without merit, and we intend to seek dismissal of and vigorously defend against these actions. While a successful outcome cannot be guaranteed, we do not reasonably expect these lawsuits to have a material adverse effect.

Environmental

One of our subsidiaries, TETRA Micronutrients, Inc. (TMI), previously owned and operated a production facility located in Fairbury, Nebraska. TMI is subject to an Administrative Order on Consent issued to American Microtrace, Inc. (n/k/a/ TETRA Micronutrients, Inc.) in the proceeding styled In the Matter of American Microtrace Corporation, EPA I.D. No. NED00610550, Respondent, Docket No. VII-98-H-0016, dated September 25, 1998 (the Consent Order), with regard to the Fairbury facility. TMI is liable for future remediation costs and ongoing environmental monitoring at the Fairbury facility under the Consent Order; however, the current owner of the Fairbury facility is responsible for costs associated with the closure of that facility.

In August of 2009, the Environmental Protection Agency (EPA), pursuant to Sections 308 and 311 of the Clean Water Act (CWA), served a request for information with regard to a spill of zinc bromide that occurred on the Mississippi River on March 11, 2009. We timely filed a response to that request for information in August 2009. In January 2010, the EPA issued a Notice of Violation and Opportunity to Show Cause related to the spill. We met with the EPA in April 2010 to discuss potential violations and penalties. It has been agreed that no injunctive relief will be required. We finalized a joint stipulation of settlement with the EPA whereby we are responsible for a penalty of $487,000, which has been submitted to the Department of Justice for approval. We expect to pay this penalty amount during the second quarter of 2011, and expect the full amoun t to be covered by insurance.
Product Purchase Obligations

 In the normal course of our Fluids Division operations, we enter into supply agreements with certain manufacturers of various raw materials and finished products. Some of these agreements have terms and conditions that specify a minimum or maximum level of purchases over the term of the agreement. Other agreements require us to purchase the entire output of the raw material or finished product produced by the manufacturer. Our purchase obligations under these agreements apply only with regard to raw materials and finished products that meet specifications set forth in the agreements. We recognize a liability for the purchase of such products at the time we receive them. As of December 31, 2010,2011, the aggregate amount of the fixed and determinable portion of the purchase obligation pursua ntpursuant to our Fluids Division’s supply agreements was approximately $266.4$250.6 million, including $13.9 million during 2011, $15.3 million during 2012, $15.3 million during 2013, $15.3 million during 2014, $15.3 million during 2015, $15.3 million during 2016, and $191.4$174.2 million thereafter, extending through 2029. Amounts purchased under these agreements for each of the years ended December 31, 2011, 2010, and 2009, and 2008 was $15.3 million, $12.4 million, $6.5 million, and $19.2$6.5 million, respectively.

NOTE K — CAPITAL STOCK

Our Restated Certificate of Incorporation authorizes us to issue 100,000,000 shares of common stock, par value $.01 per share, and 5,000,000 shares of preferred stock, par value $.01 per share. As of December 31, 2010,2011, we had 76,291,74577,423,415 shares of common stock outstanding, with 1,533,6532,249,959 shares held in treasury, and no shares of preferred stock outstanding. The voting, dividend, and liquidation rights of the holders of common stock are subject to the rights of the holders of preferred stock. The holders of common stock are entitled to one vote for each share held. There is no cumulative voting. Dividends may be declared and paid on common stock as determined by our Board of Directors, subject to any preferential dividend rights of any then outstanding preferred stock. A summary of the activity of our common shares outstanding and treasury shares held for the three year period ending December 31, 2011, is as follows:

Our Board of Directors is empowered, without approval of the stockholders, to cause shares of preferred stock to be issued in one or more series and to establish the number of shares to be included in each such series and the rights, powers, preferences, and limitations of each series. Because the Board of
F-29

Directors has the power to establish the preferences and rights of each series, it may afford the holders of any series of preferred stock preferences, powers and rights, voting or otherwise, senior to the rights of holders of
F-29

common stock. The issuance of the preferred stock could have the effect of delaying or preventing a change in control of the Company. See Note T – Stockholders’ Rights Plan for a discussion of our stockholders’ rights plan, as amended.

Upon our dissolution or liquidation, whether voluntary or involuntary, holders of our common stock will be entitled to receive all of our assets available for distribution to our stockholders, subject to any preferential rights of any then outstanding preferred stock.

In January 2004, our Board of Directors authorized the repurchase of up to $20.0 million of our common stock. During the three years ending December 31, 2010,2011, we made no purchases of our common stock pursuant to this authorization.

NOTE L — EQUITY-BASED COMPENSATION

We have various equity incentive compensation plans which provide for the granting of restricted common stock, options for the purchase of our common stock, and other performance-based, equity-based compensation awards to our executive officers, key employees, nonexecutive officers, consultants, and directors. Incentive stock options are exercisable for periods of up to ten years. Compensation cost for all share-based payments is based on the grant date fair value and is recognized in earnings over the requisite service period. Total equity-based compensation expense for the three years ended December 31, 2011, 2010, and 2009 and 2008 was $6.3 million, $7.2 million, $6.7 million, and $5.9$6.7 million, respectively, which approximated the fair value of equity-based compensation awards vesting during the periods. This expense reduced net income by $4.2 million, $4.4 million, and $3.7 million and reduced basic and diluted earnings per share by $0.06, $0.06 and $0.05, respectively, for the three years ended December 31, 2010, 2009, and 2008.

The Black-Scholes option-pricing model is used to estimate option fair values. This option-pricing model requires a number of assumptions, of which the most significant are: expected stock price volatility, the expected pre-vesting forfeiture rate, and the expected option term (the amount of time from the grant date until the options are exercised or expire). Expected volatility was calculated based upon actual historical stock price movements over the most recent periods ending December 31, 2010,2011, equal to the expected option term. Expected pre-vesting forfeitures were estimated based on actual historical pre-vesting forfeitures over the most recent periods ending December 31, 2010,2011, for the expected option term.

The TETRA Technologies, Inc. 1990 Stock Option Plan (the 1990 Plan) was initially adopted in 1985 and subsequently amended to change the name, the number, and the type of options that could be granted, as well as the time period for granting stock options. As of December 31, 2004, no further options may be granted under the 1990 Plan. We granted performance stock options under the 1990 Plan to certain executive officers. These granted options have an exercise price per share of not less than the market value at the date of issuance and are fully vested and exercisable.

In 1993, we adopted the TETRA Technologies, Inc. Director Stock Option Plan (the Directors’ Plan). In 1996, the Directors’ Plan was amended to increase the number of shares issuable under automatic grants thereunder. In 1998, we adopted the TETRA Technologies, Inc. 1998 Director Stock Option Plan as amended (the 1998 Director Plan). The purpose of the Directors’ Plan and the 1998 Director Plan (together the Director Stock Option Plans) is to enable us to attract and retain qualified individuals to serve as our directors and to align their interests more closely with our interests. The 1998 Director Plan is funded with our treasury stock and was amended and restated effective December 18, 2002, to increase the number of shares issuable thereunder, to change the types of options that may be granted thereunder, and to increase the nu mbernumber of shares issuable under automatic grants thereunder. The 1998 Director Plan was amended and restated effective June 27, 2003, and was further amended in December 2005 to increase the number of shares issuable thereunder. As of May 2, 2006, no further options may be granted under the Director Stock Option Plans.

During 1996, we adopted the 1996 Stock Option Plan for Nonexecutive Employees and Consultants (the Nonqualified Plan) to enable us to award nonqualified stock options to nonexecutive employees and consultants who are key to our performance. As of May 2, 2006, no further options may be granted under the Nonqualified Plan.

In May 2006, our stockholders approved the adoption of the TETRA Technologies, Inc. 2006 Equity Incentive Compensation Plan. Pursuant to the TETRA Technologies, Inc. 2006 Equity Incentive Compensation Plan, we were authorized to grant up to 1,300,000 shares in the form of stock options (including incentive stock options and nonqualified stock options); restricted stock; bonus stock; stock appreciation rights; and performance awards to employees, consultants, and non-employee directors. As a result of the May 2006 adoption and approval of the TETRA Technologies, Inc. 2006 Equity Incentive Compensation Plan, no further awards may be granted under our other previously existing plans. As of May 4, 2008, no further awards may be granted under the TETRA Technologies, Inc. 2006 Equity Incentive Compensation Plan.

In May 2007, our stockholders approved the adoption of the TETRA Technologies, Inc. 2007 Equity Incentive Compensation Plan. In May 2008, our stockholders approved the adoption of the TETRA Technologies, Inc. Amended and Restated 2007 Equity Incentive Compensation Plan, which among other changes, resulted in an increase in the maximum number of shares authorized for issuance. In May 2010, our stockholders approved further amendments to the TETRA Technologies, Inc. Amended and Restated 2007 Equity Incentive Compensation Plan (renamed as the 2007 Long Term Incentive Compensation Plan) which, among other changes, resulted in an additional increase in the maximum number of shares authorized for issuance. Pursuant to the 2007 Long Term Incentive Compensation Plan, we are authorized to grant up to 5,590,000 shares in the form of stock options (including incentive stock options and nonqualified stock options); restricted stock; bonus stock; stock appreciation rights; and performance awards to employees, consultants, and non-employee directors.

In June 2011, the Compressco Partners, L.P. 2011 Long Term Incentive Plan (Compressco Partners Long Term Incentive Plan) was adopted by the board of directors of Compressco Partners’ general partner. The plan is intended to promote Compressco Partners’ interests by providing to employees, consultants, and directors of its general partner incentive compensation based on common units, to encourage superior performance.

Grants of Compressco Partners Restricted Common Units

F-31 During 2011, and subsequent to the adoption of the Compressco Partners Long Term Incentive Plan, Compressco Partners granted restricted common units that generally vest over a three year period to certain employees, officers and directors of its general partner. Each of the restricted unit awards includes unit distribution rights that enable the recipient to receive accumulated cash distributions on the restricted units in the same amounts as unitholders receive cash distributions on common units. Accumulated distributions associated with each underlying restricted unit are payable upon vesting of the related restricted unit (and are forfeited if the related restricted unit is forfeited). While the initial grants of restricted units vest solely with respect to the passage of time, the Compressco Partners Long Term Incentive Plan also provides for awards of restricted units with performance-based vesting conditions. Awards that vest subject to performance-based vesting conditions are intended to further align the interests of key employees, directors and consultants of Compressco Partners’ general partner with those of its unitholders.

The weighted average fair value of options granted during the years ended December 31, 2011, 2010 2009 and 20082009 using the Black-Scholes model was $7.55, $6.00, $2.73, and $7.61$2.73 per share, respectively. Total estimated unrecognized compensation cost from unvested stock options and restricted stock as of December 31, 2010,2011, was approximately $13.0$10.6 million, which is expected to be recognized over a weighted average period of approximately 1.61.1 years.

Certain options exercised duringDuring 2011, 2010, and 2008 were exercised through the surrender of 630 and 26,304 shares, respectively, of our common stock previously owned by the option holder for a period of at least six months prior to exercise. In addition, during 2010, 2009, and 2008, we received 52,065, 6,048 6,318 and 8,1196,318 shares, respectively, of our common stock related to the vesting of certain employee restricted stock. Such surrendered shares received by us are included in treasury stock. At December 31, 2010,2011, net of options previously exercised pursuant to our various stock option plans, we have a maximum of 7,443,1847,588,617 shares of common stock issuable pursuant to stock options previously granted and outstanding and stock options authorized to be granted in the future.

NOTE M — 401(k) PLAN

We have a 401(k) retirement plan (the Plan) that covers substantially all employees and entitles them to contribute up to 70% of their annual compensation, subject to maximum limitations imposed by the Internal Revenue Code. We have historically matched 50% of each employee’s contribution up to 6% of annual compensation, subject to certain limitations as outlined in the Plan. Beginning in February 2009, we suspended company matching of employee contributions, although company matching resumed effective January 2, 2010. In addition, we can make discretionary contributions which are allocable to participants in accordance with the Plan. Total expense related to our 401(k) plan was $3.3 million, $3.3 million, and $0.7 million in 2011, 2010, and $3.3 million in 2010, 2009, and 2008, respectively.

NOTE N — DEFERRED COMPENSATION PLAN

We provide our officers, directors, and certain key employees with the opportunity to participate in an unfunded, deferred compensation program. There were thirty-twotwenty-five participants in the program at December 31, 2010.2011. Under the program, participants may defer up to 100% of their yearly total cash compensation. The amounts deferred remain our sole property, and we use a portion of the proceeds to purchase life insurance policies on the lives of certain of the participants. The insurance policies, which also remain our sole property, are payable to us upon the death of the insured. We separately contract with the participant to pay to the participant the amount of deferred compensation, as adjusted for gains or losses, invested in participant-selected investment funds. Participants may elect to receive deferrals and earnings at termination, death, or at a specified future date while still employed. Distributions while employed must be at least three years after the deferral election. The program is not qualified under Section 401 of the Internal Revenue Code. At December 31, 2010,2011, the amounts payable under the plan approximated the value of the corresponding assets we owned.

NOTE O — HEDGE CONTRACTS

We are exposed to financial and market risks that affect our businesses. We have market risk exposure in the sales prices we receive for Maritech’s oil and gas production. We have currency exchange rate risk exposure related to specific transactions denominated in a foreign currency as well as to investments in certain of our international operations. As a result of our variable rate bank credit facilities, including the variable rate credit facility of Compressco Partners, to the extent we have debt outstanding, we may face market risk exposure related to changes in applicable interest rates. We have concentrations of credit risk as a result of trade receivables fromowed to us by companies in the energy industry. In addition, we have market risk exposure in the sales prices we receive for the remainder of our oil and gas production. Our financial risk management activities include,may involve, among other measures, the use of derivative financial instruments, such

as swap and collar agreements, to hedge the impact of market price risk exposures for a po rtionexposures. Prior to the execution of Maritech’sthe purchase and sale agreement in April 2011 pursuant to which we sold substantially all of our remaining Maritech oil and gas production and for certain ofproperties in May 2011, we utilized cash flow commodity hedge transactions to reduce our foreign currency transactions. We are exposedexposure related to the volatility of oil and gas prices forprices. As indicated below, these cash flow commodity hedge contracts were liquidated in the portionsecond quarter of Maritech’s oil2011. For these and gas production that is not hedged. Weother hedge contracts, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, our strategies for undertaking various hedge transactions, and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment, or forecasted transaction. We also assess, both at the inception of the hedge and on an ongoing basis, whether the derivatives that are used in these hedging transactions are highly effective in offsetting changes in cash flows of the hedged items.

Derivative Hedge Contracts

AsIn April 2011, following the execution of the purchase and sale agreement pursuant to which Maritech agreed to sell approximately 79% of its proved reserves as of December 31, 2010, we hadliquidated our remaining oil hedge contracts and paid $14.2 million to the followingcounterparty. Therefore, from April 2011 forward, we have no remaining cash flow hedging swap contracts outstanding relating to a portion ofassociated with our Maritech subsidiary’s oil andor gas production:production.

WePrior to their liquidation during 2011, we believe that our swap agreements arewere “highly effective cash flow hedges” in managing the volatility of future cash flows associated with Maritech’s oil production. The effective portion of the change in the derivative’s fair value (i.e., that portion of the change in the derivative’s fair value that offsets the corresponding change in the cash flows of the hedged transaction) iswas initially reported as a component of accumulated other comprehensive income, which iswas classified within stockholders’ equity. This component of accumulated other comprehensive income associated with cash flow hedge derivative contracts, including any derivative contracts which have been liquidated, will bewas subsequently reclassified into product sales revenues, utilizing the specific identification method, when the hedged exposure affe ctsaffected earnings (i.e., when hedged oil and gas production volumes arewere reflected in revenues). As of December 31, 2010, the total balance (approximately $2.7 million) of accumulated other comprehensive income associated with cash flow hedge derivatives is expected to be reclassified into product sales revenue in the subsequent twelve month period. Any “ineffective” portion of the change in the derivative’s fair value iswas recognized in earnings immediately.
F-34


The fair value of hedging instruments reflects our best estimate and is based upon exchange or over-the-counter quotations, whenever they are available. Quoted valuations may not be available. Where quotes are not available, we utilize other valuation techniques or models to estimate fair values. These modeling techniques require us to make estimations of future prices, price correlation, and market volatility and liquidity. The actual results may differ from these estimates, and these differences can be positive or negative. The fair values of our oil and natural gas swap contracts as of December 31, 2010, and 2009 are as follows:

Oil and natural gas swap assets and liabilities which are classified as current assets or liabilities relate to the portion of the derivative contracts associated with hedged oil and gas production to occur over the next twelve month period. None of the oil and natural gas swap contracts contain credit risk related contingent features that would require us to post assets as collateral for contracts that are classified as liabilities.

During the second quarter of 2009, we liquidated certain cash flow hedging swap contracts associated with Maritech’s oil production in exchange for cash of approximately $23.1 million. These liquidated cash flow hedging swap contracts met the effectiveness requirements to be accounted for as hedges, and as a result, the gain on the liquidated swap contracts was retained in other comprehensive income and the $23.1 million proceeds were classified as a cash flow from operating activities during 2009 in the accompanying statements of cash flows. These gains were then reclassified into product sales revenue during 2010. Due to the suspension of a portion of Maritech’s oil and gas production following Hurricane Ike in September 2008, certain of our oil and natural gas swap contracts associated with 2008 production no longer met the effectiv eness requirements to be accounted for as hedges. As a result, the portion of other comprehensive income associated with these contracts was credited to earnings during 2008. Also as a result of suspended Maritech production, certain qualifying hedge contracts reflected ineffectiveness during the third and fourth quarter of 2008. During the fourth quarter of 2008, we liquidated each of the oil and natural gas swap contracts associated with 2008 production in exchange for cash of $6.5 million. The associated cash flows from the 2008 liquidation of these ineffective contracts were classified as cash flows from investing activities during 2008 in the accompanying consolidated statements of cash flows.

Other Hedge Contracts

Transaction gains and losses attributable to a foreign currency transaction that is designated as, and is effective as, an economic hedge of a net investment in a foreign entity is subject to the same accounting as translation adjustments. As such, the effect of a rate change on a foreign currency hedge is the same as the accounting for the effect of the rate change on the net foreign investment; both are recorded in the cumulative translation account, a component of stockholders’ equity, and are partially or fully offsetting. Prior to December 2010, our long-term debt included borrowings which were designated as a hedge of our net investment in our European calcium chloride operations. In December 2010, these euro-denominated borrowings were repaid. During the period these hedge designated euro-denominated borrowings were outstanding, chang eschanges in the foreign currency exchange rate resulted in a cumulative change to the cumulative translation adjustment account of $2.6 million, net of taxes, at December 31, 2010, with no ineffectiveness recorded.

NOTE Q — INDUSTRY SEGMENTS AND GEOGRAPHIC INFORMATION

We manage our operations through five operating segments: Fluids, Production Testing, Compressco, Offshore Services, Maritech, Production Testing and Compressco.Maritech. Beginning in the fourth quarter of 2010, certain Mexican production enhancement operations were reclassified from our Production Testing segment to our Compressco segment. Segment information for 2009 and 2008 has been revised to conform to the 2010current presentation.

Our Fluids Division manufactures and markets certain clear brine fluids, additives, and other associated products and services to the oil and gas industry for use in well drilling, completion, and workover operations both in the United States and in certain regions ofcountries in Latin America, Europe, Asia, the Middle East, and Africa. The Division also markets liquid and dry calcium chloride products manufactured at its production facilities or purchased from third-party suppliers to a variety of markets outside the energy industry.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, workover, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies in the construction or decommissioning of offshore oil and gas production platforms and pipelines, and (3) diving services involving conventional and saturated air diving.
The Maritech segment is an oil and gas exploration, development, and production company focused in the offshore, inland waters, and onshore U.S. Gulf Coast region. The Offshore Division’s Offshore Services segment performs a significant portion of the well plugging, abandonment, and decommissioning services required by Maritech.

Our Production Enhancement Division consists of two operating segments: Production Testing and Compressco. The Production Testing segment provides production testing services in many of the major oil and gas basins in the United States, as well asStates. In addition, the Production Testing segment has operations in certain onshore basins in certain regions in Mexico, Brazil, NorthernNorth Africa, the Middle East, and other internationalforeign markets.

The Compressco segment provides wellhead compression-based and other production enhancement services throughout mostmany of the onshore producing regions of the United States, as well as certain onshore basins in Mexico, Canada, Mexico,and certain countries in South America, Europe, Asia, and other international locations. Beginning June 20, 2011, following Compressco Partners’ initial public offering, we allocate and charge certain corporate and divisional direct and indirect administrative costs to Compressco Partners.

Our Offshore Division consists of two operating segments: Offshore Services and Maritech. The Offshore Services segment provides (1) downhole and subsea oil and gas services such as well plugging and abandonment, and wireline services, (2) decommissioning and certain construction services utilizing heavy lift barges and various cutting technologies with regard to offshore oil and gas production platforms and pipelines, and (3) conventional and saturated air diving services.
The Maritech segment is an oil and gas exploration, development, and production operation focused in the offshore and onshore U.S. Gulf Coast region. During 2011, Maritech sold approximately 95% of its proved reserves it owned as of December 31, 2010, and is seeking to sell its remaining oil and gas producing property interests. Maritech’s remaining operations consist primarily of the ongoing abandonment and decommissioning associated with its remaining offshore wells, facilities and production platforms. Maritech intends to acquire a significant portion of these services from the Offshore Division’s Offshore Services segment.
F-36

We generally evaluate performance and allocate resources of our segments based on profit or loss from operations before income taxes and nonrecurring charges, return on investment, and other criteria. Transfers between segments as well asand geographic areas are priced at the estimated fair value of the products or services as negotiated between the operating units. “Corporate overhead” includes corporate general and administrative expenses, corporate depreciation and amortization, interest income and expense, and other income and expense.

Estimated Quantities of Proved Oil and Gas Reserves (Unaudited)

Proved oil and gas reserves are defined as the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Reservoirs are considered proved if economic productibility is supported by either actual production or conclusive formation tests. The area of a reservoir considered proved includes (a) that portion delineated by drilling and defined by gas-oil and/or gas-water contacts, if any, and (b) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. Reserves which can be produced economically through the application of improved recovery techniq uestechniques are included in the “proved” classification when successful testing by a pilot project or the operation of an installed program in the reservoir provides support for the engineering analysis on which the project or program was based.

The reliability of reserve information is considerably affected by several factors. Reserve information is imprecise due to the inherent uncertainties in, and the limited nature of, the database upon which the estimating of reserve information is predicated. Moreover, the methods and data used in estimating reserve information are often necessarily indirect or analogical in character, rather than direct or deductive. Furthermore, estimating reserve information involves numerous judgments based upon the engineer’s educational background, professional training, and professional experience.judgments. The extent and significance of the judgments to be made are, in themselves, sufficient to render reserve information inherently imprecise.

The following information is presented with regard to our proved oil and gas reserve quantities reported in accordance with guidelines established by the SEC, and these guidelines were revised effective with the December 31, 2009 information. In 2009, we adopted SEC Release 33-8995 and the amendments to ASC Topic 932, "Extractive Industries - Oil and Gas," resulting from ASU 2010-03 (collectively, the Modernization Rules). The impact of the revision to these reserve guidelines was not considered significant to our proved oil and gas reserve volumes. The reserve values and cash flow amounts reflected in the following reserve disclosures as of December 31, 2011, 2010, and 2009, are based on the average price of oil and natural gas during the twelve month period then ended, determined as an unweighted arithmetic average of the first-day-of-the-month for each month within the period. The reserve values and cash flow amounts as of December 31, 2008, and 2007, are based on prices as of each yearend. All of Maritech’s reserves are locate dlocated in U. S. state and federal offshore waters of the Gulf of Mexico and onshore Texas and Louisiana. Proved oil and gas reserve quantities as of December 31, 2011, reflect the 2011 sale of approximately 95% of such reserves.

Revisions of previous proved reserves estimates during 2010 were primarily due to the declassification of natural gas reserves associated with a portion of Maritech’s Main Pass field due to pipeline and transportation interruptions. Revisions of previous proved reserve estimates during 2009 were the result of improved performance at Maritech’s Timbalier Bay field plus improvements in oil prices, which added to the economic lives of certain fields.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves

“Standardized measure” relates to the estimated discounted future net cash flows and major components of that calculation relating to proved reserves at the end of the year in the aggregate, based on SEC prescribed prices and costs, using statutory tax rates and using a 10% annual discount rate. The standardized measure is not an estimate of the fair value of proved oil and gas reserves. Probable and possible reserves, which may become proved in the future, are excluded from these calculations.
 
 
F-43

 
 
Furthermore, prices used to determine the standardized measure are prior to the impact of hedge derivatives and are influenced by seasonal demand and other factors and may not be representative in estimating future revenues or reserve data.

The standardized measure of discounted future net cash flows relating to proved oil and gas reserves attributed to our oil and gas properties is as follows:

NOTE T — STOCKHOLDERS’ RIGHTS PLAN

On October 27, 1998, the Board of Directors adopted a stockholders’ rights plan (the Rights Plan) designed to assure that all of our stockholders receive fair and equal treatment in the event of a proposed takeover. The Rights Plan helps to guard against partial tender offers, open market accumulations, and other abusive tactics to gain control of our company without paying an adequate and fair price in any takeover attempt. The Rights are not presently exercisable and are not represented by separate certificates. We are currently not aware of any effort of any kind to acquire control of our company.

The terms of the Rights Plan, as adopted in 1998, provide that each holder of record of an outstanding share of common stock subsequent to November 6, 1998, receives a dividend distribution of one Preferred Stock Purchase Right. The Rights Plan would be triggered if an acquiring party accumulates or initiates a tender offer to purchase 20% or more of our common stock and would entitle holders of the Rights to purchase either our stock or shares in an acquiring entity at half of market value. Each Right entitles the holder thereof to purchase 1/100 of a share of Series One Junior Participating Preferred Stock for $50.00 per share, subject to adjustment. We would generally be entitled to redeem the Rights at $.01 per Right at any time until the tenth day following the time the Rights become exercisable.
F-45


On November 6, 2008, the Board of Directors entered into a First Amendment to the Rights Agreement. The amendment extends the term of the Rights Agreement and the final expiration date of our rights thereunder, which would otherwise have expired at the close of business on November 6, 2008, until the close of business on November 6, 2018. The amendment also increases the purchase price for each 1/100 of a share of Series One Junior Participating Preferred Stock from $50.00 per share to $100.00 per share.
