TABLE OF CONTENTS

GLOSSARY OF OIL AND NATURAL GAS TERMS

Analogous Reservoir: Analogous reservoirs, as used in resource assessments, have similar rock and fluid properties, reservoir conditions (depth, temperature and pressure) and drive mechanisms, but are typically at a more advanced stage of development than the reservoir of interest and thus may provide concepts to assist in the interpretation of more limited data and estimation of recovery. When used to support proved reserves, analogous reservoir refers to a reservoir that shares all of the following characteristics with the reservoir of interest: (i) the same geological formation (but not necessarily in pressure communication with the reservoir of interest); (ii) the same environment of deposition; (iii) similar geologic structure; and (iv) the same drive mechanism.

API Gravity: A system of classifying oil based on its specific gravity, whereby the greater the gravity, the lighter the oil.

Basin: A large depression on the earth’s surface in which sediments accumulate.

Bbl: One stock tank barrel, or 42 U.S. gallons liquid volume, used in reference to oil or other liquid hydrocarbons.

Bbl/d: One Bbl per day.

Bcf: One billion cubic feet of natural gas.

Bcfe: One billion cubic feet of natural gas equivalent.

Boe: One barrel of oil equivalent, calculated by converting natural gas to oil equivalent barrels at a ratio of six Mcf of natural gas to one Bbl of oil.

Boe/d: One Boe per day.

BSEE: Bureau of Safety and Environmental Enforcement.

Btu: One British thermal unit, the quantity of heat required to raise the temperature of a one-pound mass of water by one degree Fahrenheit.

Deterministic Estimate: The method of estimating reserves or resources is called deterministic when a single value for each parameter (from the geoscience, engineering or economic data) in the reserves calculation is used in the reserves estimation procedure.

Developed Acreage: The number of acres which are allocated or assignable to producing wells or wells capable of production.

Development Project: A development project is the means by which petroleum resources are brought to the status of economically producible. As examples, the development of a single reservoir or field, an incremental development in a producing field or the integrated development of a group of several fields and associated facilities with a common ownership may constitute a development project.

Development Well: A well drilled within the proved area of an oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

Differential: An adjustment to the price of oil or natural gas from an established spot market price to reflect differences in the quality and/or location of oil or natural gas.

Dry Hole or Dry Well: A well found to be incapable of producing hydrocarbons in sufficient quantities such that proceeds from the sale of such production would exceed production expenses and taxes.

Economically Producible: The term economically producible, as it relates to a resource, means a resource which generates revenue that exceeds, or is reasonably expected to exceed, the costs of the operation. For this determination, the value of the products that generate revenue are determined at the terminal point of oil and natural gas producing activities.

Estimated Ultimate Recovery: Estimated ultimate recovery is the sum of reserves remaining as of a given date and cumulative production as of that date.

1

Exploitation: A development or other project which may target proven or unproven reserves (such as probable or possible reserves), but which generally has a lower risk than that associated with exploration projects.

1

Exploratory Well: A well drilled to find and produce oil and natural gas reserves not classified as proved, to find a new reservoir in a field previously found to be productive of oil or natural gas in another reservoir or to extend a known reservoir.

Field: An area consisting of a single reservoir or multiple reservoirs, all grouped on or related to the same individual geological structural feature and/or stratigraphic condition. The field name refers to the surface area, although it may refer to both the surface and the underground productive formations.

Gross Acres or Gross Wells: The total acres or wells, as the case may be, in which we have working interest.

ICE: Inter-Continental Exchange.

MBbl: One thousand Bbls.

MBbls/d: One thousand Bbls per day.

MBoe/d: One thousand Boe per day.

MBtu: One thousand Btu.

MBtu/d: One thousand Btu per day.

Mcf: One thousand cubic feet of natural gas.

Mcf/d: One Mcf per day.

MMBtu: One million British thermal units.

MMcf: One million cubic feet of natural gas.

MMcfe: One million cubic feet of natural gas equivalent.

MMcfe/d: One MMcfe per day.

Net Acres or Net Wells: Gross acres or wells, as the case may be, multiplied by our working interest ownership percentage.

Net Production: Production that is owned by us less royalties and production due others.

NGLs: The combination of ethane, propane, butane and natural gasolines that when removed from natural gas become liquid under various levels of higher pressure and lower temperature.

NYMEX: New York Mercantile Exchange.

Oil: Oil and condensate.

Operator: The individual or company responsible for the exploration and/or production of an oil or natural gas well or lease.

OPIS: Oil Price Information Service.

Play: A geographic area with hydrocarbon potential.

Probabilistic Estimate: The method of estimation of reserves or resources is called probabilistic when the full range of values that could reasonably occur for each unknown parameter (from the geoscience and engineering data) is used to generate a full range of possible outcomes and their associated probabilities of occurrences.

2

Productive Well: A well that produces commercial quantities of hydrocarbons, exclusive of its capacity to produce at a reasonable rate of return.

Proved Developed Reserves: Proved reserves that can be expected to be recovered from existing wells with existing equipment and operating methods.

Proved Reserve Additions2

: The sum of additions to proved reserves from extensions, discoveries, improved recovery, acquisitions and revisions of previous estimates.

Proved Reserves: Those quantities of oil and natural gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible, from a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulations, prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced, or the operator must be reasonably certain that it will commence the project, within a reasonable time. The area of the reservoir considered as proved includes (i) the area identified by drilling and limited by fluid contacts, if any and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or natural gas on the basis of available geoscience and engineering data. In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons, as seen in a well penetration, unless geoscience, engineering or performance data and reliable technology establishes a lower contact with reasonable certainty. Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated natural gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty. Reserves which can be produced economically through application of improved recovery techniques (including fluid injection) are included in the proved classification when (i) successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir, or an analogous reservoir or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and (ii) the project has been approved for development by all necessary parties and entities, including governmental entities. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price used is the average price during the twelve-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Proved Undeveloped Reserves: Proved oil and natural gas reserves that are expected to be recovered from new wells on undrilled acreage or from existing wells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage are limited to those drilling units offsetting productive units that are reasonably certain of production when drilled. Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation. Under no circumstances should estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir.

Realized Price: The cash market price less all expected quality, transportation and demand adjustments.

Recompletion: The completion for production of an existing wellbore in another formation from that which the well has been previously completed.

Reliable Technology: Reliable technology is a grouping of one or more technologies (including computational methods) that has been field tested and has been demonstrated to provide reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation.

Reserve Life: A measure of the productive life of an oil and natural gas property or a group of properties, expressed in years. Reserve life is calculated by dividing proved reserve volumes at year-end by production volumes. In our calculation of reserve life, production volumes are adjusted, if necessary, to reflect property acquisitions and dispositions.

3

Reserves: Reserves are estimated remaining quantities of oil and natural gas and related substances anticipated to be economically producible, as of a given date, by application of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to produce or a revenue interest in the production, installed means of delivering oil and natural gas or related substances to market and all permits and financing required to implement the project. Reserves should not be assigned to adjacent reservoirs isolated by major, potentially sealing, faults until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that are clearly separated from a known accumulation by a non-productive reservoir (i.e., absence of reservoir, structurally low reservoir or negative test results). Such areas may contain prospective resources (i.e., potentially recoverable resources from undiscovered accumulations).

Reservoir: A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reserves.

Resources: Resources are quantities of oil and natural gas estimated to exist in naturally occurring accumulations. A portion of the resources may be estimated to be recoverable and another portion may be considered unrecoverable. Resources include both discovered and undiscovered accumulations.

3

Spacing: The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres (e.g., 40-acre spacing) and is often established by regulatory agencies.

Spot Price: The cash market price without reduction for expected quality, transportation and demand adjustments.

Standardized Measure: The present value of estimated future net revenue to be generated from the production of proved reserves, determined in accordance with the rules, regulations or standards established by the United States Securities and Exchange Commission (“SEC”) and the Financial Accounting Standards Board (“FASB”) (using prices and costs in effect as of the date of estimation), less future development, production and income tax expenses and discounted at 10% per annum to reflect the timing of future net revenue. Future income taxes, if applicable, are computed by applying the statutory tax rate to the excess of pre-tax cash inflows over our tax basis in our oil and natural gas properties. Because we areour Predecessor was a limited partnership, we areit was generally not subject to federal or state income taxes and thus makemade no provision for federal or state income taxes in the calculation of our standardized measure. Standardized measure does not give effect to derivative transactions.

Undeveloped Acreage: Lease acreage on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves.

Wellbore: The hole drilled by the bit that is equipped for oil or natural gas production on a completed well. Also called well or borehole.

Working Interest: An interest in an oil and natural gas lease that gives the owner of the interest the right to drill for and produce oil and natural gas on the leased acreage and generally requires the owner to pay a share of the costs of drilling and production operations.

Workover: Operations on a producing well to restore or increase production.

WTI: West Texas Intermediate.

Upon emergence from the Chapter 11 proceedings.

2016 andproceedings on May 4, 2017, Developments – Debt Instruments

Throughout 2016,we adopted fresh start accounting as required by GAAP. We met the Partnership, along with its legal and financial advisors, explored various strategic alternatives with a focus on liquidity and financial flexibility. The Partnership specifically evaluated options withrequirements of fresh start accounting, which include: (i) the lenders under our revolving credit facility, dated as of December 14, 2011 (as the context may require, as amended, supplemented or otherwise modified, the “Credit Agreement” or “revolving credit facility”), by and among the Partnership, OLLC, the administrative agent and the other agents and lenders party thereto, and holders of the Partnership’s senior notes that would improve liquidity and deleverage the Partnership.

In April 2016, in connection with the semi-annual borrowing base redetermination by the lenders under our revolving credit facility, the borrowing base under our revolving credit facility was reduced from $1,175.0 million to $925.0 million. Our revolving credit facility was also amended pursuantPredecessor’s voting common units immediately prior to the tenth amendmentEffective Date received less than 50% of the voting shares of the Company and (ii) the reorganization value of our assets immediately prior to the Credit Agreement dated as of April 14, 2016, which, among other things, added additional financial restrictionsEffective Date was less than the post-petition liabilities and covenants under the Credit Agreement.

In October 2016, in connection with the second semi-annual borrowing base redetermination, the borrowing base under our revolving credit facility was reduced to $740.0 million and a further reduction of the borrowing base to $720.0 million was scheduled for December 1, 2016 in accordance with the terms of the eleventh amendment to Credit Agreement dated as of October 28, 2016.allowed claims.

In November 2016, we elected to defer an approximately $24.6 million interest payment due on November 1, 2016accordance with respect to our 7.625% senior notes due May 2021 (“2021 Senior Notes”). The interest payment was subject to a 30-day grace period under the indenture. Failure to pay such interest payment on November 1, 2016 would have resulted in certain defaults and events of default under our revolving credit facility. The lenders under the revolving credit facility, on November 1, 2016, waived such defaults and events of default through November 30, 2016 (such period from November 1, 2016 to November 31, 2016, the “Waiver Period”), in each case, subject to the terms and conditions set forth in the limited waiver and twelfth amendment (the “Waiver and Twelfth Amendment”) to our revolving credit facility.

On November 30, 2016, the Partnership, OLLC, certain subsidiaries of the Partnership, the administrative agent, and the lenders consenting thereto entered into the first amendment to the limited waiver under our revolving credit facility, extending the Waiver Period to December 16, 2016.

On November 30, 2016, the Partnership entered into forbearance agreements with certain noteholders that held approximately 51.7% of the 2021 Senior Notes and 69% of the Partnership’s 6.875% senior notes due August 2022 (“2022 Senior Notes”). Under the forbearance agreements, the noteholders agreed to forbear from exercising any and all remedies available to them as a result of the Partnership’s election not to make an interest payment of $24.6 million duePlan, on the 2021 Senior Notes. The forbearance agreements initially extended through December 7, 2016, and were subsequently extended through December 16, 2016.

On December 16, 2016, the Partnership, OLLC, certain subsidiaries of the Partnership, the administrative agent, and the lenders consenting thereto entered into the second amendment to limited waiver under our revolving credit facility, extending the Waiver Period to January 13, 2017. In addition, the forbearance agreements were extended through January 13, 2017.

In December 2016, pursuant to the second amendment to the limited waiver, the Partnership monetized certain hedge positions and used the cash proceeds to repay outstanding borrowings under our revolving credit facility. In conjunction with the hedge monetization, our borrowing base was reduced from $720.0 million to $619.0 million on December 21, 2016 and then further reduced to $530.7 million on December 22, 2016.

On December 22, 2016, the Partnership entered into a Plan Support Agreement (the “Noteholder PSA”) with holders of over an aggregate of 50.2% of the aggregate outstanding principal amount of the 2021 Senior Notes and the 2022 Senior Notes (collectively, the “Notes”), as well as reached an agreement-in-principle with the administrative agent under our revolving credit facility on the terms of a financial restructuring. Under the terms of the Noteholder PSA, the financial restructuring would be effected through the Plan. Pursuant to the terms of the Plan, which would be subject to approval of the Bankruptcy Court, it is anticipated that, among other things, on the effective date of the Plan (the “Effective Date”):Effective Date:

The restructuring transactions pursuant to the Plan are intended to be structured, as further discussed in a manner that minimizes, to the extent possible, the negative tax impact of cancellation-of-debt income to the Partnership’s existing unitholders. The Partnership expects to emerge from the Chapter 11 proceedings as a corporation, including for U.S. federal income tax purposes.

In January 2017, we monetized certain hedge positions and used a portion of the cash proceeds to repay outstanding borrowings under our revolving credit facility and kept the remaining portion as cash on hand for general partnership purposes. In conjunction with the hedge monetization, our borrowing base was reduced to $457.2 million on January 13, 2017.

10

On January 13, 2017, the Partnership entered into the third amendment to limited waiver, which extended the outside date of the Waiver Period from January 13, 2017 to January 16, 2017. In addition, the Partnership entered into a Plan Support Agreement (the “RBL PSA”) with lenders holding 100% of the loans under our revolving credit facility. The RBL PSA was entered into on terms substantially similar to those of the Noteholder PSA. In addition, among other things, the RBL PSA provided that (i) the consenting lenders (as defined in the RBL PSA) may terminate the RBL PSA upon the termination of the Noteholder PSA or if there is an amendment to the Noteholder PSA that is, or would reasonably be expected to be, adverse to the administrative agent under our revolving credit facility or the consenting lenders and (ii) each of the Debtors agreed to not file a voluntary petition for relief under Chapter 11 until the Debtors terminated certain swap agreements identified in the RBL PSA and used the net proceeds thereof to repay outstanding amounts under the revolving credit facility.  

An indicative summary of the expected terms and conditions of the Exit Credit Facility is set forth in an annex to the RBL PSA filed with our Current Report on Form 8-K filed with the SEC on January 17, 2017, which terms and conditions may include (but are not limited to) the following:

Divestitures

In July 2016, we closed a transaction to divest certain assets located in Colorado and Wyoming (the “Rockies Divestiture”) for a total purchase price of approximately $16.4 million, including final post-closing adjustments. In June 2016, we closed a transaction to divest assets located in the Permian Basin (the “Permian Divestiture”) for a total purchase price of approximately $36.7 million, including estimated post-closing adjustments. The proceeds from the divestitures were used to reduce borrowings under our revolving credit facility.

MEMP GP Acquisition

In June 2016, the Partnership acquired all of the equity interests in MEMP GP from Memorial Resource (the “MEMP GP Acquisition”) for cash consideration of approximately $0.8 million. See “—Our Principal Business Relationships” below for additional information regarding such acquisition.

Repurchase of Senior Notes

During the year ended December 31, 2016, the Partnership repurchased an aggregate principal amount of approximately $53.7 million of the 2021 Senior Notes at a weighted average price of 49.09% of the face value of the 2021 Senior Notes. During the year ended December 31, 2016, the Partnership repurchased an aggregate principal amount of approximately $32.0 million of the 2022 Senior Notes at a weighted average price of 46.50% of the face value of the 2022 Senior Notes.

On April 27, 2016, the Partnership entered into an agreement pursuant to which we agreed to acquire, among other things, all of the equity interests in our general partner, MEMP GP, from Memorial Resource for cash consideration of approximately $0.8 million. MEMP GP held an approximate 0.1% general partner interest and 50% of the incentive distribution rights ("IDRs") in us. In conjunction with the MEMP GP Acquisition, on April 27, 2016, we also entered into an agreement with an NGP affiliate pursuant to which we agreed to acquire the other 50% of the IDRs.

In connection with the closing of the transactions on June 1, 2016, our partnership agreement was amended and restated to, among other things, (i) convert the 0.1% general partner interest in the Partnership held by MEMP GP into a non-economic general partner interest, (ii) cancel the IDRs, and (iii) provide that the limited partners of the Partnership will elect the members of MEMP GP’s board of directors beginning with our next annual meeting. In addition, we terminated the omnibus agreement under which Memorial Resource provided management, administrative and operations personnel to us and our general partner, and we entered into a transition services agreement with Memorial Resource to manage certain post-closing separation costs and activities.

Our Areas of Operation

East Texas/Louisiana

Approximately 47% of our estimated proved reserves as of December 31, 20162017 and approximately 63%58% of our average daily net production for the three months ended December 31, 20162017 were located in the East Texas/Louisiana region. Our East Texas/Louisiana properties include wells and properties primarily located in the Joaquin, Carthage, Willow Springs and East Henderson fields in East Texas. Those properties collectively contained 431.7460.3 Bcfe of estimated net proved reserves as of December 31, 20162017 based on our reserve report and generated average net production of 128.7106.3 MMcfe/d for the three months ended December 31, 2016.2017. In October 2017, we launched a divestiture process for our assets in the East Texas/Louisiana region.

Rockies

Approximately 24%27% of our estimated proved reserves as of December 31, 20162017 and approximately 14%15.0% of our average daily net production for the three months ended December 31, 20162017 were located in the Rockies region. Our Rockies properties include wells and properties primarily located in the Lost Soldier and Wertz fields in Wyoming at our Bairoil complex. Our Rockies properties contained 36.844.0 MMBbls of estimated net proved oil and NGLs reserves as of December 31, 20162017 based on our reserve report and generated average net production of 28.327.0 MMcfe/d for the three months ended December 31, 2016.2017. In October 2017, we launched a divestiture process for our assets in the Rockies region.

Offshore Southern California

Approximately 19%18% of our estimated proved reserves as of December 31, 20162017 and approximately 12%13% of our average daily net production for the three months ended December 31, 20162017 were located offshore Southern California. These properties the Beta properties,(the “Beta properties”) consist of: 100% of the working interests and currently aan 87.6% average net revenue interest in three Pacific Outer Continental Shelf lease blocks (P-0300, P-0301 and P-0306), referred to as the Beta unit,Unit, in the Beta Field located in federal waters approximately 11 miles offshore the Port of Long Beach, California. Our Beta properties contained 29.329.4 MMBbls of estimated net proved oil reserves as of December 31, 20162017 based on our reserve report. Oil and gas is produced from the Beta Unit via two production platforms, referred to as the Ellen and Eureka platforms, equipped with permanent drilling rigs and associated equipment systems. On a third platform, Elly, the oil, water and gas are separated and the oil is prepared for sale, while the gas is burned as fuel for power and the water is recycled back into the reservoir for pressure maintenance. Sales quality oil is then pumped from the Elly platform to the Beta pump station located onshore at the Port of Long Beach, California via a 16-inch diameter oil pipeline, which extends approximately 17.5 miles. Amplify Energy’s wholly owned subsidiary, San Pedro Bay Pipeline Company, owns and operates the pipeline system.

Based on our reserve report, the Beta field contains more than 15% of our total estimated reserves. The following table summarizes production volumes from this field for the periods presented:

The increase in the production volumes between 2015 and the subsequent periods is primarily due to the acquisition of the remaining interests in our Beta properties from a third party.

Due to low oil and gas prices, the Beta leases were all granted royalty relief by the U.S. Department of Interior in July 2016. On our two primary producing leases, the royalty rate was reduced from 25% to 12.5%, and on our third lease, the royalty rate was reduced from 16.67% to 8.33%, for a weighted average of 12.4% overall. The royalty relief rates will apply to all hydrocarbon production up to 165,801 BOEBoe per month. Monthly production above that level and up to 331,602 BOEBoe per month will bear royalties at 1.5 times the original effective royalty rate. For monthly production above 331,602 BOEBoe per month, the royalty rate will return to the original effective royalty rates. The royalty relief rates will also be suspended in months in which the trailing twelve-month weighted average NYMEX oil and Henry Hub gas price exceeds $55.16 per BOEBoe which represents a 25% premium to the average realized price recognized by the PartnershipCompany during the qualification period. The royalty relief would end in the event that the PartnershipCompany generates no benefit from the royalty relief rates due to either higher production or realized pricing for 12 consecutive months.

The Beta properties also include two wellbore production platforms, referred to as the Ellen and Eureka platforms, equipped with permanent drilling rigs and associated equipment systems; one production handling and processing platform, referred to as the Elly platform; the San Pedro Bay Pipeline Company, which owns and operates a 16-inch diameter oil pipeline that extends approximately 17.5 miles from the Elly platform to the Beta pump station located onshore at the Port of Long Beach, California, and an onshore tankage and metering facility.11

Based on our reserve report, the Beta field contains more than 15% of our total estimated reserves. The following table summarizes production volumes from this field from the date of acquisition through December 31, 2016:

The increase in the production volumes between the current and preceding fiscal year is primarily due to the acquisition of the remaining interests in our Beta properties from a third party.

South Texas

Approximately 10%9% of our estimated proved reserves as of December 31, 2016 and approximately 11%14% of our average daily net production for the three months ended December 31, 20162017 were located in the South Texas region. Our South Texas properties include wells and properties in numerous fields located primarily in the Eagle Ford, Eagleville, NE Thompsonville, Laredo and East Seven Sisters fields. Our South Texas properties contained 88.388.6 Bcfe of estimated net proved reserves as of December 31, 20162017 based on our reserve report. Those properties collectively generated average net production of 24.225.6 MMcfe/d for the three months ended December 31, 2016.2017. In July 2017, we launched a divestiture process for our assets in the South Texas region.

Our Oil and Natural Gas Data

Our Reserves

Internal Controls. Our proved reserves were estimated at the well or unit level and audited for reporting purposes by Ryder Scott, our independent reserve engineers. The PartnershipCompany maintains internal evaluations of our reserves in a secure reserve engineering database. Ryder Scott interacts with the Partnership’sCompany’s internal petroleum engineers and geoscience professionals in each of our operating areas and with operating, accounting and marketing employees to obtain the necessary data for the reserves audit process. Reserves are reviewed and approved internally by our senior management on a semi-annualan annual basis and subject to the Chapter 11 proceedings, evaluated by our lender group on at least a semi-annual basis in connection with borrowing base redeterminations under our revolving credit facility.Credit Facility. Our reserve estimates are audited by Ryder Scott at least annually.

Our internal professional staff works closely with Ryder Scott to ensure the integrity, accuracy and timeliness of data that is furnished to them for their reserve audit process. All of the reserve information maintained in our secure reserve engineering database is provided to the external engineers. In addition, we provide Ryder Scott other pertinent data, such as seismic information, geologic maps, well logs, production tests, material balance calculations, well performance data, operating procedures and relevant economic criteria. We make all requested information, as well as our pertinent personnel, available to the external engineers as part of their audit of our reserves.

Estimated Proved Reserves

The following table presents the estimated net proved oil and natural gas reserves attributable to our properties and the standardized measure amounts associated with the estimated proved reserves attributable to our properties as of December 31, 2016,2017, based on our internally prepared reserve report audited by Ryder Scott, our independent reserve engineers. The standardized measure amounts shown in the table are not intended to represent the current market value of our estimated oil and natural gas reserves.

The data in the table above represents estimates only. Oil and natural gas reserve engineering is inherently a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured exactly. The accuracy of any reserve estimate is a function of the quality of available data and engineering and geological interpretation and judgment. Accordingly, reserve estimates may vary from the quantities of oil and natural gas that are ultimately recovered. For a discussion of risks associated with internal reserve estimates, please readsee “Item 1A. Risk Factors — Risks Related to Our Business — Our estimated proved reserves and future production rates are based on many assumptions that may prove to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of our estimated reserves.”

Future prices received for production and costs may vary, perhaps significantly, from the prices and costs assumed for purposes of these estimates. The standardized measure amounts shown above should not be construed as the current market value of our estimated oil and natural gas reserves. The 10% discount factor used to calculate standardized measure, which is required by the SEC and FASB, is not necessarily the most appropriate discount rate. The present value, no matter what discount rate is used, is materially affected by assumptions as to timing of future production, which may prove to be inaccurate.

Development of Proved Undeveloped Reserves

As of December 31, 2016,2017, we had 249.8282.3 Bcfe of proved undeveloped reserves comprised of 20.222.0 MMBbls of oil, 91.0107.1 Bcfe of natural gas and 6.37 MMBbls of NGLs. None of our PUDs as of December 31, 20162017 are scheduled to be developed on a date more than five years from the date the reserves were initially booked as PUDs. PUDs will be converted from undeveloped to developed as the applicable wells begin production.

Changes in PUDs that occurred during 20162017 were due to:

1613

Approximately 9% (418% (20 Bcfe) of our PUDs recorded as of December 31, 20152016 were developed during the twelve months ended December 31, 2016.2017. Total costs incurred to develop these PUDs were approximately $50.2$30.5 million, of which $26.5$0.8 million was incurred in fiscal year 20152016 and $23.7$29.7 million was incurred in fiscal year 2016.2017. In total, we incurred total capital expenditures of approximately $24.5$41.5 million during fiscal year 20162017 developing PUDs, which includes $0.8$11.7 million associated with PUDs to be completed in 2017.2018. As we continue to develop our properties and have more well production and completion data, we believe we will continue to realize cost savings and experience lower relative drilling and completion costs as we convert PUDs into proved developed reserves in the upcoming years. Based on our current expectations of our cash flows, we believe that we can fund the drilling of our current PUD inventory and our expansions in the next five years from our cash flow from operations and borrowings under our expected Exit Credit Facility upon approval of our plan of reorganization in the Chapter 11 proceedings.Facility. For a more detailed discussion of our liquidity position, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”

Reserves Sensitivity

Historically, commodity prices have been extremely volatile and we expect this volatility to continue for the foreseeable future. For example, for the five years ended December 31, 2016, the NYMEX-WTI oil future price ranged from a high of $110.53 per Bbl to a low of $26.21 per Bbl, while the NYMEX-Henry Hub natural gas future price ranged from a high of $6.15 per MMBtu to a low of $1.64 per MMBtu. For the year ended December 31, 2016, the West Texas Intermediate posted price ranged from a high of $54.06 per Bbl on December 28, 2016 to a low of $26.21 per Bbl on February 11, 2016 and the Henry Hub spot market price ranged from a high of $3.93 per MMBtu on December 28, 2016 to a low of $1.64 per MMBtu on March 3, 2016. NGL prices have also suffered significant recent declines. The continuation of low prices for oil or natural gas could materially and adversely affect our financial position, our results of operations, the quantities of oil and natural gas reserves that we can economically produce and our access to capital.

While it is difficult to quantify the impact of the continuation of low commodity prices on our estimated proved reserves with any degree of certainty because of the various components and assumptions used in the process of estimating reserves, the following sensitivity table is provided to illustrate the estimated impact of pricing changes on our estimated proved reserve volumes and standardized measure. In addition to different price assumptions, the sensitivity cases below include assumed capital and operating expense changes we would expect to realize under each scenario. Reductions in proved reserve volumes are attributable to reaching the economic limit sooner. The proved undeveloped reduction in volumes is a result of well locations no longer meeting our investment criteria as well as reaching the economic limit sooner. Sensitivity cases are used to demonstrate the impact that a change in price and cost environment may have on reserves volumes and standardized measure. There is no assurance that these prices or cost savings will actually be achieved.
