The interim unaudited condensed consolidated financial statements of Matador and its subsidiaries have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) but do not include all of the information and footnotes required by generally accepted accounting principles in the United States of America (“U.S. GAAP”) for complete financial statements and should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 20152016 (the “Annual Report”) filed with the SEC. The Company proportionately consolidates certain subsidiaries and joint ventures that are less-than-wholly-ownedless than wholly owned and are not involved in oil and natural gas exploration, including San Mateo, and the net income and equity attributable to the non-controlling interest in these subsidiaries have been reported separately as required by Accounting Standards Codification (“ASC”) 810. The Company proportionately consolidates certain joint ventures that are less-than-wholly-ownedless than wholly owned and are involved in oil and natural gas exploration. All intercompany accounts and transactions have been eliminated in consolidation. In management’s opinion, these interim unaudited condensed consolidated financial statements include all adjustments, consisting only of normal, recurring adjustments, which are necessary for a fair presentation of the Company’s interim unaudited condensed consolidated financial statements as of June 30, 2016.2017. Amounts as of December 31, 20152016 are derived from the Company’s audited consolidated financial statements in the Annual Report.
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These estimates and assumptions may also affect disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Company’s interim unaudited condensed consolidated financial statements are based on a number of significant estimates, including accruals for oil and natural gas revenues, accrued assets and liabilities primarily related to oil and natural gas operations, stock-based compensation, valuation of derivative instruments and oil and natural gas reserves. The estimates of oil and natural gas reserves quantities and future net cash flows are the basis for the calculations of depletion and impairment of oil and natural gas properties, as well as estimates of asset retirement obligations and certain tax accruals. While the Company believes its estimates are reasonable, changes in facts and assumptions or the discovery of new information may result in revised estimates. Actual results could differ from these estimates.
Change in Accounting PrincipleReclassifications
DuringCertain reclassifications have been made to the second quarter of 2016,prior periods’ financial statements to conform to the Company adopted Accounting Standards Update (“ASU”) 2016-09, Compensation - Stock Compensation (Topic 718),which simplifies several aspectscurrent period presentation. As a result of the accountinggrowth of the Company’s midstream operations, these operations met the required threshold for employee share-based payment transactions, including accountingsegment reporting. As a result, $0.9 million for the three months ended June 30, 2016 and $1.4 million for the six months ended June 30, 2016 were reclassified from other income tax, forfeitures, statutory tax withholding requirements, classificationsto third-party midstream services revenues. In addition, $1.1 million related to midstream operating costs for the three months ended June 30, 2016 and $2.1 million for the six months ended June 30, 2016 were reclassified from lease operating expenses to plant and other midstream services operating expenses. These reclassifications had no effect on previously reported results of awards as either equity or liability and classification of taxes in the statement ofoperations, cash flows requiring either retrospective, modified retrospective or prospective transition. The amended guidance also requires an entity to record excess tax benefits and deficiencies in the income statement. The adoption of this ASU had no impact on any period presented for (i) the Company’s financial position or statements of operations, as the Company currently has a valuation allowance against its net deferred tax assets, or (ii) the Company’s statements of cash flows, as the Company has historically accounted for taxes paid for net share settlement as a financing activity as required under this ASU. In addition, the Company uses historical forfeiture rates to estimate future forfeitures attributable to the service-based vesting requirements not being met and will continue to do so upon adoption of this ASU.retained earnings.
Property and Equipment
The Company uses the full-cost method of accounting for its investments in oil and natural gas properties. Under this method, the Company is required to perform a ceiling test each quarter whichthat determines a limit, or ceiling, on the capitalized costs of oil and natural gas properties based primarily on the after-tax estimated future net cash flows from oil and natural gas properties using a 10% discount rate and the arithmetic average of first-day-of-the-month oil and natural gas prices for the prior 12-month period. For the three and six months ended June 30, 2017, the cost center ceiling was higher than the capitalized costs

12-month period. Dueof oil and natural gas properties; no impairment charge was necessary. However, due primarily to declines in oil and natural gas prices in early 2016, the capitalized costs of oil and natural gas properties exceeded the cost center ceiling for the three and six months ended June 30, 2016, and as a result, the Company recorded impairment charges to its net capitalized costs of $78.2 million and $158.6 million, respectively, in its interim unaudited condensed consolidated statements of operations of $78.2 million and $229.0 million for the three months ended June 30, 2016 and 2015, respectively, and $158.6 million and $296.2 million for the six months ended June 30, 2016 and 2015, respectively.
As a non-cash item, the full-cost ceiling impairment impacts the accumulated depletion and the net carrying value of the Company’s assets on its consolidated balance sheet, as well as the corresponding consolidated shareholders’ equity, but it has no impact on the Company’s consolidated net cash flows as reported. Changes in oil and natural gas production rates, oil and natural gas prices, reserves estimates, future development costs and other factors will determine the Company’s actual ceiling test computation and impairment analyses in future periods.operations.
The Company capitalized approximately $4.0$5.2 million and $1.9$4.0 million of its general and administrative costs for the three months ended June 30, 20162017 and 2015,2016, respectively, and approximately $1.7$1.9 million and $1.3$1.7 million of its interest expense for the three months ended June 30, 20162017 and 2015,2016, respectively. The Company capitalized approximately $6.0$10.8 million and $3.5$6.0 million of its general and administrative costs for the six months ended June 30, 20162017 and 2015,2016, respectively, and approximately $2.2$3.2 million and $2.3$2.2 million of its interest expense for the six months ended June 30, 20162017 and 2015,2016, respectively.
Earnings (Loss) Per Common Share
The Company reports basic earnings (loss) attributable to Matador Resources Company shareholders per common share, which excludes the effect of potentially dilutive securities, and diluted earnings (loss) attributable to Matador Resources Company shareholders per common share, which includes the effect of all potentially dilutive securities unless their impact is anti-dilutive.
The following table sets forth the computation of diluted weighted average common shares outstanding for the three and six months ended June 30, 20162017 and 20152016 (in thousands).

A total of 2.9 million options to purchase shares of the Company’s common stock and 0.1 million restricted stock units were excluded from the diluted weighted average common shares outstanding for both the three and six months ended June 30, 2016, respectively, because their effects were anti-dilutive. Additionally, 0.9 million restricted shares, which are participating securities, were excluded from the calculations above for both the three and six months ended June 30, 2016, respectively, as the security holders do not have the obligation to share in the losses of the Company.
A total of 2.5 million options to purchase shares of the Company’s common stock and 0.1 million restricted stock units were excluded from the diluted weighted average common shares outstanding for both the three and six months ended June 30, 2015, respectively, and zero and 1.5 million preferred shares were excluded from the calculations above for both the three and six months ended June 30, 2015, respectively, because their effects were anti-dilutive. Additionally, 0.7 million restricted shares, which are participating securities, were excluded from the calculations above for both the three and six months ended June 30, 2015, respectively, as the security holders do not have the obligation to share in the losses of the Company.
Recent Accounting Pronouncements
Revenue from Contracts with Customers. In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASUAccounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606),which specifies how and when to recognize revenue. In addition, thisThis standard requires expanded disclosures surrounding revenue recognition and is intended to improve, and converge with international standards, the financial reporting requirements for revenue from contracts with customers. ThisIn August 2015, the FASB issued ASU will become2015-14, which defers the effective date of ASU 2014-09 for one year to fiscal years beginning after December 15, 2017. Early adoption is permitted for fiscal years beginning after December 15, 2017 with early adoption permitted2016. In May 2016, the FASB issued ASU 2016-11, which rescinds guidance from the SEC on accounting for periods beginning after

The Company is currently evaluating the impact, if any,new guidance, including (i) identification of the adoptionrevenue streams and (ii) review of this ASU on its consolidated financial statements.contracts and procedures currently in place.
Leases. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP. This ASU will become effective for fiscal years beginning after December 15, 2018 with early adoption permitted. Entities are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial

The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.
Statement of Cash Flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230), which specifies that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This ASU will become effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The update should be applied using a retrospective transition method to each period presented. The Company believes that the impact of the adoption of this ASU will change the presentation of its beginning and ending cash balances on its Consolidated Statements of Cash Flows and eliminate the presentation of changes in restricted cash balances from investing activities on its Consolidated Statements of Cash Flows.
Clarifying the Definition of a Business. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805), which specifies the minimum inputs and processes required for an integrated set of assets and activities to meet the definition of a business. This ASU will become effective for fiscal years beginning after December 15, 2017 with early adoption permitted. Entities are required to apply guidance prospectively upon adoption. The Company is currently evaluating the impact of the adoption of this ASU on its consolidated financial statements.

NOTE 5 - DEBT
At June 30, 20162017 and August 3, 2016,2, 2017, the Company had $400$575.0 million of outstanding 6.875% senior notes due 2023, (the “Notes”), no borrowings outstanding under the Company’s revolving credit agreement (the “Credit Agreement”) and approximately $0.6 million and $0.8 million in outstanding letters of credit issued pursuant to the Credit Agreement.
Credit Agreement respectively.
The borrowing base under the Credit Agreement is determined semi-annually as of May 1 and November 1 by the lenders based primarily on the estimated value of the Company’s proved oil and natural gas reserves at December 31 and June 30 of each year, respectively. Both the Company and the lenders may request an unscheduled redetermination of the borrowing base once each between scheduled redetermination dates. On May 3, 2016,During the borrowing base underfirst quarter of 2017, the Credit Agreement was reduced to $300.0 million from $375.0 million based on the lenders’lenders completed their review of the Company’s proved oil and natural gas reserves at December 31, 2015. At June 30, 2016, and on April 28, 2017, the borrowing base availablewas increased to $450.0 million and the maximum facility amount remained at $500.0 million. The Company elected to keep the borrowing commitment at $400.0 million. Borrowings under the Credit Agreement remained $300.0 million.are limited to the least of the borrowing base, the maximum facility amount and the elected commitment. The Credit Agreement matures on October 16, 2020.
In the event of a borrowing basean increase in the elected commitment, the Company is required to pay a fee to the lenders equal to a percentage of the amount of the increase, which is determined based on market conditions at the time of the borrowing base increase. Total deferred loan costs were $1.1 million at June 30, 2017, and these costs are being amortized over the term of the Credit Agreement, which approximates amortization of these costs using the effective interest method. If, upon a redetermination of the borrowing base, the borrowing base were to be less than the outstanding borrowings under the Credit Agreement at any time, the Company would be required to provide additional collateral satisfactory in nature and value to the lenders to increase the borrowing base to an amount sufficient to cover such excess or to repay the deficit in equal installments over a period of six months.
The Company believes that it was in compliance with the terms of the Credit Agreement at June 30, 2017.
Senior Unsecured Notes
On April 14, 2015 and December 9, 2016, the Company issued $400.0 million and $175.0 million, respectively, of 6.875% senior notes due 2023 (collectively, the “Notes”). The Notes mature on April 15, 2023, and interest is payable semi-annually in arrears on April and October 15 of each year.
On May 24, 2017, and pursuant to a registered exchange offer, the Company exchanged all of the $175.0 million of Notes issued on December 9, 2016, which were privately placed, for a like principal amount of 6.875% senior notes due 2023 that have been registered under the Securities Act of 1933, as amended. The terms of such registered Notes are substantially the same as the terms of the original Notes except that the transfer restrictions, registration rights and provisions for additional interest relating to the original Notes do not apply to the registered Notes.

NOTE 6 - INCOME TAXES
The Company’s deferred tax assets exceedexceeded its deferred tax liabilities at June 30, 2017 due to the deferred tax assets generated by the full-cost ceiling impairment charges recorded;recorded in prior periods; as a result, the Company established a valuation allowance against most of the deferred tax assets beginning in the third quarter of 2015. The Company retainsretained a full valuation allowance at June 30, 20162017 due to uncertainties regarding the future realization of its deferred tax assets. The valuation allowance will continue to be recognized until the realization of future deferred tax benefits are more likely than not to be utilized.
The total income tax benefit for the three and six months ended June 30, 2015 differed from amounts computed by applying the U.S. federal statutory tax rate to loss before income taxes due primarily to state tax apportionments and nondeductible expenses.

NOTE 9 - FAIR VALUE MEASUREMENTS
The Company measures and reports certain financial and non-financial assets and liabilities on a fair value basis. Fair value is 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 (exit price). Fair value measurements are classified and disclosed in one of the following categories in the fair value hierarchy:categories.
Level 1Unadjusted quoted prices for identical, unrestricted assets or liabilities in active markets.
Level 2Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability. This category includes those derivative instruments that are valued with industry standard models that consider various inputs including: (i) quoted forward prices for commodities, (ii) time value of money and (iii) current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these inputs are observable in the marketplace throughout the full term of the derivative instrument and can be derived from observable data or supported by observable levels at which transactions are executed in the marketplace.
Level 3Unobservable inputs that are not corroborated by market data that reflect a company’s own market assumptions.
Financial and non-financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment, which may affect the valuation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels.
The following tables summarize the valuation of the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis in accordance with the classifications provided above as of June 30, 2017 and December 31, 2016 (in thousands).

NOTE 10 - COMMITMENTS AND CONTINGENCIES
Processing, Transportation and Salt Water Disposal Commitments

Natural Gas and NGL Processing and Transportation CommitmentsEagle Ford
Effective September 1, 2012, the Company entered into a firm five-year natural gas processing and transportation agreement whereby the Company committed to transport the anticipated natural gas production from a significant portion of its Eagle Ford acreage in South Texas through the counterparty’s system for processing at the counterparty’s facilities. The agreement also includes firm transportation of the natural gas liquids extracted at the counterparty’s processing plant downstream for fractionation. After processing, the residue natural gas is purchased by the counterparty at the tailgate of its processing plant and further transported under its natural gas transportation agreements. The arrangement contains fixed processing and liquids transportation and fractionation fees, payable by the Company, and the revenue the Company receives for the residue natural gas varies with the quality of natural gas transported to the processing facilities and the contract period.
Under this agreement, if the Company does not meet 80% of the maximum thermal quantity transportation and processing commitments in a contract year, it will be required to pay a deficiency fee per MMBtu of natural gas deficiency. Any quantity in excess of the maximum MMBtu delivered in a contract year can be carried over to the next contract year for purposes of calculating the natural gas deficiency. During certain prior periods, the Company had an immaterial natural gas deficiency, and the counterparty to this agreement waived the deficiency fee. The Company’s remaining aggregate undiscounted minimum commitments under this agreement are $2.1 million at June 30, 2016. The Company paid $0.8$0.5 million and $1.4$0.8 million in processing and transportation fees under this agreement during the three months ended June 30, 20162017 and 2015,2016, respectively, and $1.7$1.0 million and $2.7$1.7 million in processing and transportation fees under this agreement during the six months ended June 30, 2017 and 2016, and 2015, respectively. The future undiscounted minimum payment under this agreement as of June 30, 2017 was $0.2 million.
Delaware Basin — Loving County, Texas Natural Gas Processing
In late 2015, the Company entered into a 15-year, fixed-fee natural gas gathering and processing agreement whereby the Company committed to deliver the anticipated natural gas production from a significant portion of its Loving County, Texas acreage in West Texas through the counterparty’s gathering system for processing at the counterparty’s facility.facilities. Under this agreement, if the Company does not meet the volume commitment for gatheringtransportation and processing at the facilityfacilities in a contract year, it will be required to pay a deficiency fee per MMBtu of natural gas deficiency. At the end of each year of the agreement, the Company can elect to have the previous year’s actual gatheringtransportation and processing volumes be the new minimum commitment for each of the remaining years of the contract. As such, the Company has the ability to unilaterally reduce the gathering and processing commitment if the Company’s production in the Loving County area is less than the Company’s currently projected production. If the Company ceased operations in this area at June 30, 2016,2017, the total deficiency fee required to be paid would be approximately $8.5$11.6 million. In addition, if the Company elects to reduce the gathering and processing commitment in any year, the Company has the ability to elect to increase the committed volumes in any future year to the originally agreed gathering and processing commitment. Any quantity in excess of the volume commitment delivered in a contract year can be carried over to the next contract year for purposes of calculating the natural gas deficiency. The Company paid approximately $2.8 million in processing and gathering fees under this agreement during the three months ended June 30, 2016 and $4.7 million during the six months ended June 30, 2016. The Company can elect to either sell the residue gas to the counterparty at the tailgate of its processing plant or have the counterparty deliver to the Company the residue gas in-kind to be sold to third parties downstream of the plant.
Other Commitments
The Company does not own or operate its own drilling rigs, but instead enters into contracts with third parties for such rigs. These contracts establish daily rates for the drilling rigs and the term of the Company’s commitment for the drilling services to be provided, which have typically been for one year or less, although the Company has entered into longer-term contracts in order to secure new drilling rigs equipped with the latest technology in plays that were until recently experiencing heavy demand for drilling rigs. The Company would incur a termination obligation if the Company elected to terminate a contract and the drilling contractor were unable to secure work for the contracted drilling rigs or if the drilling contractor were unable to secure replacement work for the contracted drilling rigs at the same daily rates being charged to the Company prior to the end of their respective contract terms. The Company’s undiscounted minimum outstanding aggregate termination obligations under its drilling rig contracts were approximately $43.0 million at June 30, 2016.
The Company entered into an agreement in late 2015 with a third party for the engineering, procurement, construction and installation of a natural gas processing plant in the Rustler Breaks prospect area in Eddy County, New Mexico. The plant is expected to process a portion of the Company’s natural gas produced from certain of its wells in the Delaware Basin, as well as third-party natural gas once the plant is completed and placed in service, which is scheduled to occur later in August 2016. At June 30, 2016, total remaining commitments under this contract were $4.6 million, and the Company made payments totaling $4.3 million during the three months ended June 30, 2016 and $17.8 million during the six months ended June 30, 2016.

The Company paid approximately $3.7 million and $2.8 million in natural gas processing and gathering fees under this agreement during the three months ended June 30, 2017 and 2016, respectively, and $6.8 million and $4.7 million in natural gas processing and gathering fees under this agreement during the six months ended June 30, 2017 and 2016, respectively.The Company can elect to either sell the residue gas to the counterparty at the tailgate of its processing plants or have the counterparty deliver to the Company the residue gas in-kind to be sold to third parties downstream of the plants.
Delaware Basin — San Mateo
In connection with the Joint Venture, effective as of February 1, 2017, the Company dedicated its current and future leasehold interests in the Rustler Breaks and Wolf asset areas pursuant to 15-year, fixed-fee natural gas, oil and salt water gathering agreements and salt water disposal agreements. In addition, the Company dedicated its current and future leasehold interests in the Rustler Breaks asset area pursuant to a 15-year, fixed-fee natural gas processing agreement (collectively with the gathering and salt water disposal agreements, the “Operational Agreements”). The Joint Venture will provide the Company with firm service under each of the Operational Agreements in exchange for certain minimum volume commitments. The minimum contractual obligation under the Operational Agreements at June 30, 2017 was approximately $256.4 million.
Beginning in May 2017, a subsidiary of San Mateo entered into certain agreements with third parties for the engineering, procurement, construction and installation of an expansion of the Black River Processing Plant, including required compression. The expansion is expected to be placed into service in 2018. San Mateo’s total commitments under these agreements are $56.9 million. The subsidiary of San Mateo paid approximately $7.9 million and $9.9 million under these agreements during the three and six months ended June 30, 2017. As of June 30, 2017, the remaining obligations under these agreements were $47.0 million, which are expected to be incurred within the next year.
Other Commitments
The Company does not own or operate its own drilling rigs, but instead enters into contracts with third parties for such drilling rigs. These contracts establish daily rates for the drilling rigs and the term of the Company’s commitment for the drilling services to be provided, which have typically been for two years or less. The Company would incur a termination obligation if the Company elected to terminate a contract and if the drilling contractor were unable to secure replacement work for the contracted drilling rigs or if the drilling contractor were unable to secure replacement work for the contracted drilling rigs at the same daily rates being charged to the Company prior to the end of their respective contract terms. The Company’s undiscounted minimum outstanding aggregate termination obligations under its drilling rig contracts were approximately $42.0 million at June 30, 2017.
At June 30, 2016,2017, the Company had agreedoutstanding commitments to participate in the drilling and completion of various non-operated wells.

Legal Proceedings
The Company is a party to several lawsuits encountered in the ordinary course of its business.

NOTE 12 - SEGMENT INFORMATION

The Company operates in two business segments: (i) exploration and production and (ii) midstream. The exploration and production segment is engaged in the acquisition, exploration and development of oil and natural gas properties and is currently focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. The Company also operates in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas. The midstream segment conducts midstream operations in support of the Company’s exploration, development and production operations and provides natural gas processing, natural gas, oil and salt water gathering services and salt water disposal services to third parties on a limited basis. As of February 17, 2017, substantially all of the Company’s midstream operations in the Rustler Breaks and Wolf asset areas in the Delaware Basin are conducted through San Mateo (see Note 3).
The following tables present selected financial information for the periods presented regarding the Company’s business segments on a stand-alone basis, corporate expenses that are not allocated to a segment and the consolidation and elimination entries necessary to arrive at the financial information for the Company on a consolidated basis (in thousands). On a consolidated basis, midstream services revenues consist primarily of those revenues from midstream operations related to third parties, including working interest owners in the Company’s operated wells. All midstream services revenues associated with Company-owned production are eliminated in consolidation. In evaluating the operating results of the exploration and production and midstream segments, the Company does not allocate certain expenses to the individual segments, including general and administrative expenses. Such expenses are reflected in the column labeled “Corporate.”

Overview
We are an independent energy company founded in July 2003 and engaged in the exploration, development, production and acquisition of oil and natural gas resources in the United States, with an emphasis on oil and natural gas shale and other unconventional plays. Our current operations are focused primarily on the oil and liquids-rich portion of the Wolfcamp and Bone Spring plays in the Delaware Basin in Southeast New Mexico and West Texas. We also operate in the Eagle Ford shale play in South Texas and the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas. Additionally, we conduct midstream operations, primarily through our midstream joint venture, San Mateo Midstream, LLC (“San Mateo” or the “Joint Venture”), in support of our exploration, development and production operations and provide natural gas processing, natural gas, oil and salt water gathering services and salt water disposal services to third parties on a limited basis.
Second Quarter and Year-to-Date Highlights
Quarterly oil equivalent and natural gas production results for the second quarter of 2016 were the best in our history. For the three months ended June 30, 2016,2017, our total oil equivalent production was 2.553.4 million BOE, and our average daily oil equivalent production was 28,02236,922 BOE per day, of which 13,51619,423 Bbl per day, or 48%53%, was oil and 87.0105.0 MMcf per day, or 52%47%, was natural gas. Our total oil equivalent production of 2.551.77 million BOEBbl for the three months ended June 30, 20162017 increased 5%44% year-over-year from 2.421.23 million BOEBbl for the three months ended June 30, 2015.2016. Our natural gas production of 9.6 Bcf for the three months ended June 30, 2017 increased 21% year-over-year from 7.9 Bcf for the three months ended June 30, 2016. For the six months ended June 30, 2016,2017, our total oil equivalent production was 4.726.3 million BOE, and our average daily oil equivalent production was 25,93434,972 BOE per day, of which 12,49518,876 Bbl per day, or 48%54%, was oil and 80.696.6 MMcf per day, or 52%46%, was natural gas. Our total oil equivalent production of 4.723.4 million BOEBbl for the six months ended June 30, 20162017 increased 4%50% year-over-year from 4.542.3 million BOEBbl for the six months ended June 30, 2015.2016. Our natural gas production of 17.5 Bcf for the six months ended June 30, 2017 increased 19% year-over-year from 14.7 Bcf for the six months ended June 30, 2016.
DuringFor the second quarter of 2016, our oil and natural gas revenues were $69.3 million, a decrease of 21% from oil and natural gas revenues of $87.8 million during the second quarter of 2015. Our oil revenues and natural gas revenues decreased 23% and 14%, respectively, to approximately $52.7 million and $16.6 million, respectively, primarily as a result of significantly lower oil and natural gas prices realized for the second quarter of 2016, as compared to $68.5 million and $19.3 million, respectively, for the second quarter of 2015. We realized weighted average oil and natural gas prices of $42.84 per Bbl and $2.10 per Mcf, respectively, in the second quarter of 2016, as compared to weighted average oil and natural gas prices of $54.37 per Bbl and $2.78 per Mcf, respectively, realized in the second quarter of 2015. In addition, our oil production decreased 2% to 1.23 million Bbl in the second quarter of 2016, as compared to 1.26 million Bbl produced in the second quarter of 2015. The decrease in oil production was primarily a result of declining oil production in the Eagle Ford shale where2017, we have not drilled and completed any new operated wells since early in the second quarter of 2015, which offset increasing oil production from our ongoing delineation and development drilling in the Delaware Basin. The decrease in oil and natural gas revenues was somewhat mitigated by the 14% increase in our natural gas production to 7.9 Bcf in the second quarter of 2016, as compared to 7.0 Bcf in the second quarter of 2015. The increase in natural gas production was primarily a result of our ongoing delineation and development drilling in the Delaware Basin, which offset declining natural gas production in the Eagle Ford and

Haynesville shales where we have significantly reduced our activity since late 2014 and early 2015. For the three months ended June 30, 2016, thereported net lossincome attributable to Matador Resources Company shareholders was $105.9of approximately $28.5 million, or $0.28 per diluted common share on a decrease of 33% from theGAAP basis, as compared to a net loss attributable to Matador Resources Company shareholders of $157.1$105.9 million, or $1.15 per diluted common share, for the second quarter of 2016. For the second quarter of 2017, our Adjusted EBITDA attributable to Matador Resources Company shareholders (“Adjusted EBITDA”), a non-GAAP financial measure, was $72.7 million, as compared to Adjusted EBITDA of $38.9 million during the threesecond quarter of 2016. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Liquidity and Capital Resources — Non-GAAP Financial

Measures.” For more information regarding our financial results for the second quarter of 2017, see “— Results of Operations” below.
For the six months ended June 30, 2015. For2017, we reported net income attributable to Matador Resources Company shareholders of approximately $72.5 million, or $0.72 per diluted common share on a GAAP basis, as compared to a net loss attributable to Matador Resources Company shareholders of $213.5 million, or $2.40 per diluted common share, for the threesix months ended June 30, 2016, our Adjusted EBITDA was $39.0 million, a decrease of 42% from Adjusted EBITDA of $66.7 million during2016. For the threesix months ended June 30, 2015.2017, our Adjusted EBITDA, is a non-GAAP financial measure.measure, was $142.6 million, as compared to Adjusted EBITDA of $56.1 million during the six months ended June 30, 2016. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Liquidity and Capital Resources — Non-GAAP Financial Measures.” For more information regarding our financial results for the second quarter of 2016, see “— Results of Operations” below.
During the six months ended June 30, 2016, our oil and natural gas revenues were $113.3 million, a decrease of 25% from oil and natural gas revenues of $150.3 million during the six months ended June 30, 2015. This decrease was attributable to a sharp decline in weighted average oil and natural gas prices to $36.43 per Bbl and $2.07 per Mcf, respectively, realized in the six months ended June 30, 2016 from weighted average oil and natural gas prices of $49.48 per Bbl and $2.80 per Mcf, respectively, realized in the six months ended June 30, 2015. The decrease in our oil and natural gas revenues was somewhat mitigated by the 8% increase in our natural gas production to 14.7 Bcf in the six months ended June 30, 2016, as compared to 13.6 Bcf in the six months ended June 30, 2015. Our oil production remained flat at 2.27 million Bbl for both the six months ended June 30, 2016 and 2015. The changes in oil and natural gas production were attributable to the same operations noted above for the three months ended June 30, 2016 and 2015. For the six months ended June 30, 2016, the net loss attributable to Matador Resources Company shareholders was $213.5 million, an increase of 3% from the net loss attributable to Matador Resources Company shareholders of $207.3 million during the six months ended June 30, 2015. For the six months ended June 30, 2016, our Adjusted EBITDA was $56.2 million, a decrease of 52% from Adjusted EBITDA of $116.8 million during the six months ended June 30, 2015. Adjusted EBITDA is a non-GAAP financial measure. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Liquidity and Capital Resources — Non-GAAP Financial Measures.” For more information regarding our financial results for the six months ended June 30, 2016,2017, see “— Results of Operations” below.
During the second quarter of 2016,2017, we operated threecontinued our focus on the exploration, delineation and development of our Delaware Basin acreage in Loving County, Texas and Lea and Eddy Counties, New Mexico. We began 2017 operating four drilling rigs in the Delaware Basin and continued to do so throughout the first quarter of 2017. In late April 2017, we added a fifth drilling rig in the Delaware Basin and expect to operate five rigs in the Delaware Basin throughout the remainder of 2017, including three rigs in our Rustler Breaks and Antelope Ridge asset areas, one rig in our Wolf and Jackson Trust asset areas and one rig in our Ranger/Arrowhead and Twin Lakes asset areas. We expect to direct over 90% of our estimated 2017 capital expenditure budget (excluding capital expenditures related to acreage, mineral and seismic data acquisitions) to drilling and completion and midstream activities in the Delaware Basin. TwoAt June 30, 2017, we had incurred approximately $241 million, or 51%, of these rigs were operatingour 2017 capital expenditure budget of between $456 and $484 million (excluding capital expenditures related to acreage, mineral and seismic data acquisitions).
In July 2017, we took delivery of a sixth drilling rig on a temporary basis for the purpose of drilling a second salt water disposal well in the Rustler Breaks prospectasset area for San Mateo. Upon delivery of the sixth drilling rig, the salt water disposal well was not ready to spud, so at August 2, 2017, we were using this rig to drill an additional oil and natural gas well in Eddy County, New Mexico,our Rustler Breaks asset area. At August 2, 2017, we had no plans to use this sixth rig to drill additional oil and one was operatingnatural gas wells for the remainder of 2017.
We also finished drilling our five-well program in the Wolf prospect areaEagle Ford shale in Loving County, Texas. In mid-July, one of the rigs operating in the Rustler Breaks prospect area was moved to the Ranger/Arrowhead prospect area in the northern portion of our acreage position in Lea County, New Mexico to begin drilling a three-well program, with all three wells testing the Third Bone Spring sand. At August 3, 2016, we continued to operate three drilling rigs, with one rig operating in each of the Wolf, Rustler Breaks and Ranger/Arrowhead prospect areas.
DuringSouth Texas during the second quarter of 2016,2017. Two of these wells were completed and turned to sales in mid-June 2017. The other three wells were completed and turned to sales in early July 2017, and thus, did not contribute to second quarter 2017 production volumes. The rig used to drill these five wells was released in May 2017, and we have no additional operated drilling activities planned in the Eagle Ford shale for the remainder of 2017.
We completed and turned to sales a total of 21 gross (14.2 net) wells in the Delaware Basin during the second quarter of 2017, including 16 gross (13.5 net) operated and five gross (0.7 net) non-operated horizontal wells. In the Rustler Breaks asset area, we began producing oil and natural gas from 22a total of 13 gross (17.2(8.2 net) wells induring the Delaware Basin,second quarter of 2017, including 19nine gross (16.4(7.6 net) operated and twofour gross (0.3(0.6 net) non-operated horizontalwells. Of the nine gross operated wells in the Rustler Breaks asset area, five were Wolfcamp A-XY completions, one was a Wolfcamp A-Lower completion and Wolf prospect areas. We alsothree were Wolfcamp B-Blair completions. In addition, we began producing oil and natural gas from onefive gross (0.5(4.2 net) vertical well at Rustler Breaks as part of a successful acreage-holding operation with our working interest partners. We completed and placed on production 11 gross (7.9 net) horizontaloperated wells at Rustler Breaksin the Wolf asset area during the second quarter of 2016,2017, including nineone Wolfcamp A-XY completion and four Second Bone Spring completions. In the Ranger, Arrowhead and Twin Lakes asset areas, we began producing oil and natural gas from a total of one gross (7.6(0.1 net) non-operated well, one gross (0.7 net) operated well and twoone gross (0.3 net) non-operated wells. These nine gross operated horizontal wells included five Wolfcamp A-XY completions and four Wolfcamp B completions; both non-operated wells were also completed in the Wolfcamp B. In addition, we completed and placed on production 10 gross (8.8(1.0 net) operated horizontal wells at Wolfwell, respectively, during the second quarter of 2016, including five Wolfcamp A-X, three Wolfcamp A-Y, one Wolfcamp A-Lower and one2017. The well in the Arrowhead asset area, a Second Bone Spring completions.completion, and the well in the Twin Lakes asset area, a Wolfcamp D completion, were the first operated horizontal wells we had tested in their respective asset areas.
As a result of our ongoing drilling and completion operations in these prospectasset areas, our Delaware Basin production has continued to increase over the past twelve months. Our total Delaware Basin production for the second quarter of 20162017 was 27,622 BOE per day, consisting of 16,645 Bbl of oil per day and 65.9 MMcf of natural gas per day, a 90% increase from production of 14,525 BOE per day, consisting of 9,789 Bbl of oil per day and 28.4 MMcf of natural gas per day, a 2.3-fold increase from production of 6,187 BOE per day, consisting of 4,468 Bbl of oil per day and 10.3 MMcf of natural gas per day, in the second quarter of 2015.2016. The Delaware Basin contributed approximately 86% of our daily oil production and approximately 63% of our daily natural gas production in the second quarter of 2017, as compared to approximately 72% of our daily oil production and approximately 33% of our daily natural gas production in the second quarter of 2016, as compared to approximately 32% of our daily oil production and approximately 13% of our daily natural gas production in the second quarter of 2015.
At June 30, 2016, we had incurred $198.0 million, or approximately 61%, of our 2016 capital expenditure budget of $325.0 million. This was in line with our budgeted capital expenditures of $192.0 million in the first six months of 2016.
The five Wolfcamp A-XY wells completed and placed on production in the Rustler Breaks prospect area in the second quarter of 2016 were consistent with or better than the best Wolfcamp A-XY wells drilled by us in this prospect area to date. The Paul 25-24S-28E RB #221H well (Paul #221H) tested at the highest 24-hour initial potential flow rate of any Wolfcamp A-XY well we have drilled at Rustler Breaks—1,701 BOE per day (74% oil)—and early performance from this well indicates that it may be the best Wolfcamp A-XY well drilled to date at Rustler Breaks. During the second quarter of 2016,2017 and through August 2, 2017, we tested our first two wells drilled in the deepest bench of the Wolfcamp B (Blair Shale) at Rustler Breaks. This is the third bench of the Wolfcamp B we have successfully tested at Rustler Breaks. These three target benches of the Wolfcamp B occur starting

acquired approximately 300 feet into the 1,000-foot thick Wolfcamp B interval at Rustler Breaks, and are each about 200 to 250 feet apart vertically.
The 24-hour initial potential flow rates from the two Wolfcamp B-Blair wells—the Jimmy Kone 05-24S-28E RB #228H and the Tiger 14-24S-28E RB #227H—were the two highest 24-hour test results we have reported8,300 net acres in the Delaware Basin, to date at 2,438 BOE per daymostly in and 1,812 BOE per day, respectively, at about 33% oil. These 24-hour initial potential test results compare favorably to thosearound our existing acreage positions, including new leasing activities, acquisitions of small interests from other wells completed in the middle Wolfcamp B, the Tiger 14-24S-28E RB #224Hmineral and Janie Conner 13-24S-28E RB #224H wells, which had 24-hour initial potential rates of 1,533 BOE per day (43% oil) and 1,703 BOE per day (59% oil), respectively. The oil volumes from these lower Wolfcamp B completions were reasonably comparable to those in the middle Wolfcamp B, while the natural gas volumes were higher.
In the Wolf prospect area, we are pleased with the test results observed from the Dorothy White 82-TTT-B33 WF #123H well (Dorothy White #123H), a Second Bone Spring completion. Both this well and the Dick Jay 92-TTT-B01 WF #124H well, another Second Bone Spring completion reportedworking interest owners in our Quarterly Report on Form 10-Q foroperated wells and acreage trades or term assignments with other operators. We incurred capital expenditures of approximately $28.0 million to acquire this additional acreage throughout the three months ended March 31, 2016, are significant improvements over our first Second Bone Spring well drilled in the Wolf prospect area. In particular, the recently-completed Dorothy White #123H well has continued to perform well in its first two months of production, having averaged approximately 450 Bbl of oil per day and 1.8 MMcf of natural gas per day (60% oil) during that period.
Our operational efficiencies continue to improve at Rustler Breaks and throughout our Delaware Basin, drilling and completions program. Through the first half of 2016, we have further reduced our average drilling time as compared to 2014 and 2015 in the Wolfcamp A-XY by approximately 28% and 12%, respectively, and in the Wolfcamp B by approximately 47% and 32%, respectively. Our fastest-drilled Wolfcamp A-XY well, the Paul #221H well, was drilled in 13.8 days from spud to a total depth of 14,468 feet, a decrease of 44% from the average drilling time in late 2014, and our fastest-drilled Wolfcamp B well, the B. Banker 33-23S-28E RB #221H well, was drilled in 17.5 days from spud to a total depth of 15,151 feet, a decrease of 58% from the average drilling time in 2014. These drilling times of 13.8 and 17.5 days are faster than our 2016 drilling objectives of 14 days for the Wolfcamp A-XY and 18 days for the Wolfcamp B, respectively, from spud to total depth, which we had targeted to achieve by year-end 2016. We delivered faster drilling times as a result of our increased knowledge of the geology and our experience with drilling in the Rustler Breaks area, as well as improvements in drilling the curve between the vertical and horizontalfor new 3-D seismic data across portions of these wells and continued applications of improved drill bit and bottomhole assembly technologies.
Due in part to these improvements in drilling times, continued innovation by our technical staff and lower-than-anticipated stimulation costs, the costs associated with recent Wolfcamp A-XY and Wolfcamp B wells at Rustler Breaks continued to decline and were among the lowest we have achieved to date. We have been able to drill, complete and equip several wells in the Wolfcamp A-XY for just under $5 million on each well and in the Wolfcamp B for approximately $5.5 million each. These costs were just under or in line with our targets for year-end 2016 for the Wolfcamp A-XY and the Wolfcamp B, all while maintaining or increasing the size and effectiveness of the completion design.
Operational efficiencies continued to improve in the Wolf prospect area as well. Through the first half of 2016, we have further reduced our average drilling time in the Wolfcamp A-X and A-Y by approximately 57% and 24% as compared to 2014 and 2015, respectively, and in the Second Bone Spring by approximately 42% as compared to our first well drilled in the Second Bone Spring in 2015. Our fastest-drilled Wolfcamp A well, the Dorothy White 82-TTT-B33 #203H well, was drilled in 17.3 days from spud to a total depth of 15,550 feet, a decrease of 60% from the 2014 average drilling time and faster than our Wolfcamp A drilling objective of 18 days from spud to total depth that we had targeted to achieve by year-end 2016 at Wolf. The Dorothy White #123H well was drilled in approximately 12.6 days from spud to total depth, with drilling times being faster than our 2016 year-end drilling target of 13 days for our Second Bone Spring wells. In the Dorothy White #123H well, our drilling engineers were also able to eliminate a second intermediate casing string typically used when drilling the Second Bone Spring in thisasset area. Not only did eliminating this casing string save approximately $650,000 in well costs on each well, but it also provides for larger casing to be set through the lateral, thereby reducing hydraulic horsepower costs during fracturing operations and enhancing the number of artificial lift options available in the future. Total cost to drill, complete and equip the Dorothy White #123H well was just over $4 million, but we estimate that we should be able to drill, complete and equip Second Bone Spring wells in this area for under $4 million in the near future.
Well costs associated with recent Wolfcamp A-X and A-Y wells drilled and completed in the Wolf prospect area also continued to decline. Costs to drill, complete and equip recent Wolfcamp A wells have ranged between $5 million and $6 million, with a number of these wells at or below our 2016 year-end target of $5.5 million. As at Rustler Breaks, we attribute these cost savings to the innovation and use of new technologies by our drilling, completions and production teams, as well as lower-than-expected stimulation costs.
At December 31, 2015,August 2, 2017, we held approximately 157,100189,500 gross (88,800(108,000 net) acres in the Permian Basin in Southeast New Mexico and West Texas, primarily in

the Delaware Basin in Lea and Eddy Counties, New Mexico and Loving County, Texas. Between January 1, 2016 and August 3, 2016, we added approximately 6,400 gross (3,100 net) acres in the Delaware Basin. As a result,

at August 3, 2016 our total acreage position in Southeast New Mexico and West Texas was approximately 161,900 gross (91,100 net) acres, almost all of which was in the Delaware Basin. During the second quarter of 2016, we also acquired mineral ownership in approximately 7,900 gross (1,700 net) acres in our Rustler Breaks, Wolf and Ranger/Arrowhead prospect areas. We plan to continue our leasing and acquisitionacquisitions efforts in the Delaware Basin during the remainder of 20162017 and may also considercontinue acquiring acreage in the Eagle Ford shale and Haynesville shaleshales as strategic opportunities are identified.
Estimated Proved Reserves
The following table sets forth our estimated total proved oil and natural gas reserves at June 30, 2016,2017, December 31, 20152016 and June 30, 2015.2016. Our production and proved reserves are reported in two streams: oil and natural gas, including both dry and liquids-rich natural gas. Where we produce liquids-rich natural gas, such as in the Delaware Basin and the Eagle Ford shale, the economic value of the natural gas liquids associated with the natural gas is included in the estimated wellhead natural gas price on those properties where the natural gas liquids are extracted and sold. These reserves estimates were based on evaluations prepared by our engineering staff and have been audited for their reasonableness and conformance with SEC guidelines by Netherland, Sewell & Associates, Inc., independent reservoir engineers. These reserves estimates were prepared in accordance with the SEC’s rules for oil and natural gas reserves reporting. The estimated reserves shown are for proved reserves only and do not include any unproved reserves classified as probable or possible reserves that might exist for our properties, nor do they include any consideration that would be attributable to interests in unproved and unevaluated acreage beyond those tracts for which proved reserves have been estimated. Proved oil and natural gas reserves are quantities of oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Our total proved reserves are estimated using a conversion ratio of one Bbl of oil per six Mcf of natural gas.

_______________
(1)Numbers in table may not total due to rounding.
(2)Our estimated proved reserves, Standardized Measure and PV-10 were determined using index prices for oil and natural gas, without giving effect to derivative transactions, and were held constant throughout the life of the properties. The unweighted arithmetic averages of the first-day-of-the-month prices for the period from July 2016 through June 2017 were $45.42 per Bbl for oil and $3.01 per MMBtu for natural gas, for the period from January 2016 through December 2016 were $39.25 per Bbl for oil and $2.48 per MMBtu for natural gas and for the period from July 2015 through June 2016 were $39.63 per Bbl for oil and $2.24 per MMBtu for natural gas, for the period from January 2015 through December 2015 were $46.79 per Bbl for oil and $2.59 per MMBtu for natural gas and for the period from July 2014 through June 2015 were $68.17 per Bbl for oil and $3.39 per MMBtu for natural gas. These prices were adjusted by property for quality, energy content, regional price differentials, transportation fees, marketing deductions and other factors affecting the price received at the wellhead. We report our proved reserves in two streams, oil and natural gas, and the economic value of the natural gas liquids associated with the natural gas is included in the estimated wellhead natural gas price on those properties where the natural gas liquids are extracted and sold.
(3)One thousand barrels of oil.
(4)One billion cubic feet of natural gas.
(5)One thousand barrels of oil equivalent, estimated using a conversion ratio of one Bbl of oil per six Mcf of natural gas.

(6)Standardized Measure represents the present value of estimated future net cash flows from proved reserves, less estimated future development, production, plugging and abandonment costs and income tax expenses, discounted at 10% per annum to reflect the timing of future cash flows. Standardized Measure is not an estimate of the fair market value of our properties.
(7)PV-10 is a non-GAAP financial measure and generally differs from Standardized Measure, the most directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. PV-10 is not an estimate of the fair market value of our properties. We and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies and of the potential return on investment related to the companies’ properties without regard to the specific tax characteristics of such entities. Our PV-10 at June 30, 2016,2017, December 31, 20152016 and June 30, 20152016 may be reconciled to the Standardized Measure of discounted future net cash flows at such dates by reducing our PV-10 by the discounted future income taxes associated with such reserves. The discounted future income taxes at June 30, 2016,2017, December 31, 20152016 and June 30, 20152016 were in millions,$85.0 million, $6.5 million and $4.9 $12.4 and $78.7,million, respectively.
At June 30, 2017, our estimated total proved oil and natural gas reserves were 134.4 million BOE, including 75.0 million Bbl of oil and 356.5 Bcf of natural gas, with a Standardized Measure of $1,001.9 million and a PV-10, a non-GAAP financial measure, of $1,086.9 million. At December 31, 2016, our estimated total proved oil and natural gas reserves were 105.8 million BOE, including 57.0 million Bbl of oil and 292.6 Bcf of natural gas, and at June 30, 2016, our estimated total proved oil and natural gas reserves were 95.5 million BOE, an all-time high, including 52.3 million Bbl of oil and 258.7 Bcf of natural gas, with a Standardized Measure of $468.3 million and a PV-10, a non-GAAP financial measure, of $473.2 million. At December 31, 2015, our estimated total proved oil and natural gas reserves were 85.1 million BOE, including 45.6 million Bbl of oil and 236.9 Bcf of natural gas, and at June 30, 2015, our estimated total proved oil and natural gas reserves were 87.0 million BOE, including 40.6 million Bbl of oil and 278.6 Bcf of natural gas. Our proved oil reserves of 75.0 million Bbl at June 30, 2017 increased 32%, as compared to 57.0 million Bbl at December 31, 2016, and increased 43%, as compared to 52.3 million Bbl at June 30, 2016, also an all-time high, increased 15%, as compared to 45.6 million Bbl at December 31, 2015, and increased 29%, as compared to 40.6 million Bbl at June 30, 2015.2016. At June 30, 2016,2017, approximately 41% of our total proved reserves were proved developed reserves, 55%56% of our total proved reserves were oil and 45%44% of our total proved reserves were natural gas. Primarily as a result of the continued decline in commodity prices used to estimate proved reserves at June 30, 2016, certain of our proved undeveloped reserves were reclassified to contingent resources and are no longer considered proved reserves under applicable SEC guidelines.
As a result of our drilling, completion and delineation activities in West Texas and Southeast New Mexico and West Texas since 2014, our Delaware Basin oil and natural gas reserves continue tohave become a more significant component of our total oil and natural gas reserves. Our estimated Delaware Basin proved oil and natural gas reserves have increased approximately two-fold63% from 33.966.2 million BOE at June 30, 2015, or 39% of our total proved oil and natural gas reserves, including 21.9 million Bbl of oil and 71.4 Bcf of natural gas, to 66.2 million BOE,2016, or 69% of our total proved oil and natural gas reserves, including 40.3 million Bbl of oil and 155.3 Bcf of natural gas, to 108.1 million BOE, or 80% of our total proved oil and natural gas reserves, including 64.9 million Bbl of oil and 259.2 Bcf of natural gas, at June 30, 2016.2017.

Oil and natural gas revenues. Our oil and natural gas revenues decreased $18.5increased $44.4 million to $69.3$113.8 million, or a decrease of 21%64%, for the three months ended June 30, 2016,2017, as compared to $87.8$69.3 million for the three months ended June 30, 2015.2016. Our oil revenues decreased $15.8increased $28.6 million, or 23%54%, to $81.3 million for the three months ended June 30, 2017, as compared to $52.7 million for the three months ended June 30, 2016, as compared to $68.5 million for the three months ended June 30, 2015. The decreaseincrease in oil revenues resulted primarily from (i) a lowerhigher weighted average oil price realized for the three months ended June 30, 20162017 of $42.84$46.01 per Bbl, as compared to $54.37$42.84 per Bbl realized for the three months ended June 30, 2015. In addition, our2016, and (ii) the 44% increase in oil production decreased 2% to 1.231.77 million Bbl of oil for the three months ended June 30, 2016,2017, or about 13,51619,423 Bbl of oil per day, as compared to just over 1.261.23 million Bbl of oil, or about 13,84713,516 Bbl of oil per day, for the three months ended June 30, 2015. This small decrease2016. The increase in oil production wasis primarily a result of declining oil productionattributable to our ongoing delineation and development drilling activities in the Eagle Ford shale where we have not drilled and completed any new operated wells since early in the second quarter of 2015. We reduced our drilling program from five operated rigs in the first quarter of 2015 to two operated rigs in the second quarter of 2015, as compared to the three operated rigs as of August 3, 2016.Delaware Basin. Our natural gas revenues decreasedincreased by $2.7$15.8 million, or 14%95%, to $32.4 million for the three months ended June 30, 2017, as compared to $16.6 million for the three months ended June 30, 2016, as compared to $19.3 million for the three months ended June 30, 2015.2016. The decreaseincrease in natural gas revenues resulted from (i) a lowerhigher weighted average natural gas price realized for the three months ended June 30, 20162017 of $2.10$3.40 per Mcf, as compared to $2.78$2.10 per Mcf realized for the three months ended June 30, 2015. The lower weighted average natural gas price was partially mitigated by2016, and (ii) the 14%21% increase in our natural gas production to 9.6 Bcf for the three months ended June 30, 2017, as compared to 7.9 Bcf for the three months ended June 30, 2016, as compared to 7.0 Bcf for the three months ended June 30, 2015.2016. The increasedincrease in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin, which offset decliningBasin.

Third-party midstream services revenues. Our third-party midstream services revenues increased to $2.1 million, or 129%, for the three months ended June 30, 2017, as compared to $0.9 million for the three months ended June 30, 2016. This increase was primarily attributable to a significant increase in natural gas gathering and processing revenues to approximately $1.6 million for the three months ended June 30, 2017, as compared to $0.3 million for the three months ended June 30, 2016, due to (i) our natural gas gathering system and the Black River cryogenic natural gas processing plant (the “Black River Processing Plant”) in the Rustler Breaks asset area being placed into service in the second half of 2016 and (ii) increased natural gas production in the Eagle Ford and Haynesville shales where we have significantly reduced our activity since late 2014 and early 2015.Wolf asset area.

Realized gain on derivatives. Our realized net gain on derivatives was $0.6 million for the three months ended June 30, 2017, as compared to a realized net gain of $2.5 million for the three months ended June 30, 2016, as compared to2016. We realized a realizednet gain of $13.8$0.6 million from our oil derivative contracts for the three months ended June 30, 2015.2017, resulting from oil prices below the floor prices of certain of our oil costless collar contracts. We realized net gains of $0.6 million and $1.9 million from our oil and natural gas derivative contracts, respectively, for the three months ended June 30, 2016. For the three months ended June 30, 2015, we realized a net gain of $10.5 million, $2.7 million and $0.5 million attributable to our oil, natural gas and natural gas liquids (“NGL”) derivative contracts, respectively. The realized gains on our2016, resulting from oil and natural gas derivative contracts during the respective periods were attributable to commodity prices being below the floor prices of the majority of our oil and natural gas costless collar contracts. We realized an average gain of approximately $0.47 per Bbl hedged on all of our open oil costless collar contracts during the three months ended June 30, 2017, as compared to an average gain of $0.81 per Bbl hedged for the three months ended June 30, 2016. Our oil volumes hedged for the three months ended June 30, 2017 were 78% higher as compared to the three months ended June 30, 2016. We realized an average gain of approximately $0.65 per MMBtu hedged on all of our open natural gas costless collar contracts for the three months ended June 30, 2016 and 2015. The realized gain on our NGL derivative contracts during the three months ended June 30, 2015 resulted from NGL prices that were lower than the fixed prices of our NGL swap contracts; we had no open NGL derivative contracts in 2016. The average floor prices of our oil costless collar contracts were $42.48 per Bbl and $70.38 per Bbl for the three months ended June 30, 2016 and 2015, respectively. The average ceiling prices of our oil costless collar contracts were $61.16 per Bbl and $87.72 per Bbl for the three months ended June 30, 2016 and 2015, respectively. During the second quarter of 2016, our natural gas costless collar contracts had average floor and ceiling prices of $2.60 per MMBtu and $3.53 per MMBtu, respectively, as compared to $3.26 per MMBtu and $3.94 per MMBtu, respectively, during the second quarter of 2015. Our total oil and natural gas volumes hedged for the three months ended June 30, 20162017 were 1%109% higher and 31% lower, respectively, than the total oil and natural gas volumes hedged for the same period in 2015.three months ended June 30, 2016.

Oil and natural gas revenues. Our oil and natural gas revenues decreased by approximately $37.1increased $115.3 million to $228.6 million, or 25%102%, for the six months ended June 30, 2017, as compared to approximately $113.3 million for the six months ended June 30, 2016, as compared2016. Our oil revenues increased $82.1 million, or 99%, to $150.3$165.0 million for the six months ended June 30, 2015. Our oil revenues decreased by 26%2017, as compared to $82.8 million for the six months ended June 30, 2016, as compared to $112.3 million2016. The increase in oil revenues resulted from (i) a higher weighted average oil price realized for the six months ended June 30, 2015. The decrease in oil revenues resulted from a lower weighted average oil price realized in the six months ended June 30, 20162017 of $36.43$48.28 per Bbl, as compared to $49.48$36.43 per Bbl realized for the six months ended June 30, 2015. Our2016, and (ii) the 50% increase in oil production remained essentially flat at 2.27to 3.42 million Bbl of oil in the six months ended June 30, 2016,2017, or about 12,49518,876 Bbl of oil per day, as compared to 2.27 million Bbl of oil, or about 12,53412,495 Bbl of oil per day, in the six months ended June 30, 2015. Increasing2016. This increased oil production dueis primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin offset declining oil production from the Eagle Ford shale during this period.Basin. Our natural gas revenues decreasedincreased by $7.7$33.2 million, or 20%109%, to $63.7 million for the six months ended June 30, 2017, as compared to $30.4 million for the six months ended June 30, 2016, as compared to $38.1 million2016. The increase in natural gas revenues resulted from (i) a higher weighted average natural gas price realized for the six months ended June 30, 2015. Our2017 of $3.64 per Mcf, as compared to $2.07 per Mcf realized for the six months ended June 30, 2016, and (ii) the 19% increase in our natural gas production increased by 8%to 17.5 Bcf for the six months ended June 30, 2017, as compared to 14.7 Bcf for the six months ended June 30, 2016, as compared to 13.6 Bcf for the six months ended June 30, 2015.2016. The increase in natural gas production was primarily attributable to increased natural gas production associated with our operationsongoing delineation and development drilling activities in the Delaware Basin and new, non-operated Haynesville shale wells completed and placed on production on our Elm Grove properties in Northwest Louisiana duringBasin.
Third-party midstream services revenues. Our third-party midstream services revenues increased to $3.7 million, or 163%, for the latter half of 2015 and intosix months ended June 30, 2017, as compared to $1.4 million for the six months ended June 30, 2016. This production increase was largely offset byprimarily attributable to a lower weighted averagesignificant increase in natural gas price of $2.07 per Mcf realized duringgathering and processing revenues to approximately $2.8 million for the six months ended June 30, 2017, as compared to $0.7 million for the six months ended June 30, 2016, as compareddue to a weighted average(i) our natural gas pricegathering system and the Black River Processing Plant in the Rustler Breaks asset area being placed into service in the second half of $2.80 per Mcf2016 and (ii) increased natural gas production in our Wolf asset area.
Realized gain (loss) on derivatives. Our realized duringnet loss on derivatives was $1.7 million for the six months ended June 30, 2015, and declining natural gas production in the Eagle Ford shale where we have not drilled and completed any new operated wells since early in the second quarter of 2015.
Realized2017, as compared to a net gain on derivatives. We realized a gain on derivatives of approximately $9.5 million for the six months ended June 30, 2016, as compared to a gain2016. We realized net losses of approximately $32.3$1.1 million and $0.6 million from our oil and natural gas derivative contracts, respectively, for the six months ended June 30, 2015. For2017, resulting from oil and natural gas prices that were above the six months ended June 30, 2016, weceiling prices of certain of our oil and natural gas costless collar contracts. We realized net gains of approximately $6.0 million and $3.5 million attributable tofrom our oil and natural gas derivative contracts, respectively. For the six months ended June 30, 2015, we realized net gains of approximately $25.0 million, $6.3 million and $1.0 million attributable to our oil, natural gas and NGL derivative contracts, respectively. The net gain realized from our derivative contractsrespectively, for the six months ended June 30, 2016, resultedresulting from oil and natural gas prices that were below the floor prices of the majority of our oil and natural gas derivativecostless collar contracts. DuringWe realized an average loss of approximately $0.48 per Bbl hedged on all of our open oil costless collar contracts during the six months ended June 30, 2016, our natural gas costless collar contracts had average floor and ceiling prices of $2.62 per MMBtu and $3.56 per MMBtu, respectively,2017, as compared to $3.50 per MMBtu and $4.31 per MMBtu, respectively, for the six months ended June 30, 2015.

Three Months Ended June 30, 20162017 as Compared to Three Months Ended June 30, 20152016
Production taxes, transportation and marketing.processing. Our production taxes, transportation and marketingprocessing expenses increased by $0.3$2.3 million to $10.6$12.9 million,, or an increase of 3%22%, for the three months ended June 30, 2017, as compared to $10.6 million for the three months ended June 30, 2016. The increase in production taxes, transportation and processing expenses was primarily attributable to the increase in our production taxes of $3.1 million to $6.9 million for the three months ended June 30, 2017, as compared to $3.9 million for the three months ended June 30, 2016,, as compared primarily due to $10.3 millionthe 64% increase in oil and natural gas revenues for the three months ended June 30, 2015. On a unit-of-production basis, our production taxes and marketing expenses decreased by 2%2017, as compared to $4.14 per BOE for the three months ended June 30, 2016, as compared2016. In addition, the production tax rates in New Mexico are higher than production tax rates in Texas. As more of our oil and natural gas production becomes attributable to $4.24 per BOENew Mexico, we expect to continue to experience increased production tax expenses. The increased production taxes were partially offset by a decrease in transportation and processing expenses. Transportation and processing expenses decreased to $5.9 million for the three months ended June 30, 2015. The increase in production taxes and marketing expenses was primarily attributable2017, as compared to higher natural gas marketingtransportation and processing expenses of $6.7 million for the three months ended June 30, 2016. This decrease of $0.8 million was primarily due to the start-up in late August 2016 of the Black River Processing Plant, which processes most of the natural gas produced in our Rustler Breaks asset area in Eddy County, New Mexico, and the 34% decrease in natural gas production between the two periods in Northwest Louisiana and East Texas where our transportation and processing charges are highest on a unit-of-production basis. On a unit-of-production basis, our production taxes, transportation and processing expenses decreased 7% to $3.83 per BOE for the three months ended June 30, 2017, as

compared to $4.14 per BOE for the three months ended June 30, 2016. On a unit‑of-production basis, these second quarter 2017 expenses benefited from significantly higher total oil equivalent production, which increased 32% in the second quarter of 2017, as compared to natural gas marketing and processingthe second quarter of 2016.
Lease operating. Our lease operating expenses increased by $3.9 million to $16.0 million, or an increase of $6.132%, for the three months ended June 30, 2017, as compared to $12.2 million for the three months ended June 30, 2015. This increase of $0.6 million was primarily due to the increase in natural gas production in the Delaware Basin as2016. Our lease operating expenses on a percentage of our total natural gas productionunit-of-production basis remained consistent at $4.77 per BOE for the three months ended June 30, 2016,2017, as compared to $4.78 per BOE for the three months ended June 30, 2016. Our total oil equivalent production increased 32% to approximately 3.4 million BOE for the three months ended June 30, 2017 from approximately 2.6 million BOE for the three months ended June 30, 2016. The increase in lease operating expenses on an absolute basis for the three months ended June 30, 2017, as compared to the three months ended June 30, 2015. Natural gas marketing2016, was primarily attributable to an increase in costs of services and processing expenses are higherequipment related to the increased number of wells at June 30, 2017, as compared to June 30, 2016, as a result of our increased delineation and development activities in the Delaware Basin,Basin.
Plant and other midstream services operating. Our plant and other midstream services operating expenses increased by $1.9 million to $2.9 million, an increase of 177%, for the three months ended June 30, 2017, as compared to $1.1 million for the Eagle Ford shale, as the natural gas gathering and processing infrastructure

has yet to meet the demand for these services duethree months ended June 30, 2016. This increase was partially attributable to the increased drilling activity inexpenses associated with our salt water disposal operations of $1.5 million for the Delaware Basin over the last few years. We anticipate that we will incur lower marketing and processing expenses for most of the natural gas produced in Eddy County, New Mexico once the cryogenic natural gas processing plant we are constructing and installing in the Rustler Breaks prospect area is completed and operational. On an absolute basis, our production taxes decreased by $0.3 millionthree months ended June 30, 2017, as compared to $3.9$0.7 million for the three months ended June 30, 2016, as compared to $4.2 million for the three months ended June 30, 2015, primarily due to the 21% decrease in oil and natural gas revenuesa result of additional salt water disposal wells operating in the second quarter of 2016 as compared to2017. Most of the second quarter of 2015.
Lease operating expenses. Our lease operating expenses decreased by $1.8 million to $13.2 million, or a decrease of 12%, for the three months ended June 30, 2016, as compared to $15.0 million for the three months ended June 30, 2015. Our lease operating expenses per unit of production decreased 16% to $5.17 per BOE for the three months ended June 30, 2016, as compared to $6.18 per BOE for the three months ended June 30, 2015. Our total oil equivalent production increased 5% to approximately 2.55 million BOE for the three months ended June 30, 2016 from approximately 2.42 million BOE for the three months ended June 30, 2015. The decrease achieved in lease operating expenses on a unit-of-production basisremaining increase was attributable to several key factors, including (i) decreased field supervisory costs as a numberexpenses of third-party contractors became full-time employees during the second quarter of 2016, (ii) decreased supervisory and chemical costs$0.8 million associated with our Eagle Ford operations and (iii) increased oil equivalent production as compared to the same periodBlack River Processing Plant, which began operating in 2015.August 2016.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses decreasedincreased by $20.5$10.0 million to $31.2$41.3 million, or a decreasean increase of 40%32%, for the three months ended June 30, 2016,2017, as compared to $51.8$31.2 million for the three months ended June 30, 2015.2016. On a unit-of-production basis, our depletion, depreciation and amortization expenses decreasedincreased slightly to $12.28 per BOE for the three months ended June 30, 2017, as compared to $12.25 per BOE for the three months ended June 30, 2016, or a decrease of 43%, from $21.39 per BOE for the three months ended June 30, 2015.2016. The decreaseincrease in theour total depletion, depreciation and amortization expenses was primarily attributable to (i) increased well costs, largely as a result of increased well stimulation costs, since December 31, 2016, and (ii) the decrease in unamortized property costs resulting from the full-cost ceiling impairments recorded in 2015 and 2016, as well as the 10%32% increase in our total estimated proved oil and natural gas production to 3.4 million BOE for the three months ended June 30, 2017, as compared to 2.6 million BOE for the three months ended June 30, 2016. The impact of the increase in well costs and oil and natural gas production on depletion, depreciation and amortization was mostly offset by higher total proved reserves between the two periods. Thisof 134.4 million BOE, or an increase of 41%, at June 30, 2017, as compared to total proved reserves of 95.5 million BOE at June 30, 2016. The increase in total proved oil and natural gas reserves was primarily attributable to the continued delineation and development of our acreage in the Delaware Basin. In addition, depreciation expenses attributable to our midstream segment were approximately $1.3 million for the three months ended June 30, 2017, as compared to $0.5 million for the three months ended June 30, 2016.
Full-cost ceiling impairment. At June 30, 2016, the net capitalized costs of our oil and natural gas properties exceeded the full-cost ceiling by $78.2 million. As a result,2017, we recorded anno impairment charge of $78.2 million to the net capitalized costs of our oil and natural gas properties. This full-cost ceiling impairment is reflected in our interim unaudited condensed consolidated statement of operations for the three months ended June 30, 2016. We also recorded an impairment charge of $229.0$78.2 million to the net capitalized costs of our oil and natural gas properties for the three months ended June 30, 2015.2016.
In determining the full-cost ceiling impairment at June 30, 2016, we estimated the PV-10 of our total proved oil and natural gas reserves using the unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended June 30, 2016 as required under the guidelines established by the SEC, which were $39.63 per Bbl and $2.24 per MMBtu, respectively.  If the unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended June 30, 2016 had been $37.90 per Bbl and $2.26 per MMBtu, respectively, while all other factors remained constant, our full-cost ceiling would have been reduced by an additional $48.5 million on a pro forma basis.  The aforementioned pro forma prices, as estimated for the twelve month period October 2015 through September 2016, were calculated using a 12-month unweighted arithmetic average of oil and natural gas prices, which included the oil and natural gas prices on the first day of the month for the 11 months ended August 2016, with the price for August 2016 being held constant for September 2016.  This pro forma increase in the excess of our net capitalized costs above the full-cost ceiling is attributable to a pro forma reduction of $48.5 million in the PV-10 of our total proved oil and natural gas reserves, including a pro forma decrease in our estimated total proved reserves to 94.9 million BOE, or a reduction of approximately 1%, from our reported estimated proved reserves of 95.5 million BOE at June 30, 2016, primarily attributable to certain proved undeveloped locations that would no longer be classified as proved undeveloped reserves using the pro forma prices. This calculation of the impact of lower commodity prices on our estimated total proved oil and natural gas reserves and our full-cost ceiling was prepared based on the presumption that all other inputs and assumptions are held constant with the exception of oil and natural gas prices.  Therefore, this calculation strictly isolates the impact of commodity prices on our full-cost ceiling and proved reserves.  The impact of prices is only one of several variables in the estimation of our proved reserves and full-cost ceiling and other factors could have a significant impact on our future proved reserves and the present value of future cash flows.  The other factors that impact future estimates of proved reserves include, but are not limited to, extensions and discoveries, acquisitions of proved reserves, changes in drilling and completion and operating costs, drilling results, revisions due to well performance and other factors, changes in development plans and production, among others.  There are numerous uncertainties inherent in the estimation of proved oil and natural gas reserves and accounting for oil and natural gas properties in subsequent periods and this pro forma estimate should not be construed as indicative of our development plans or future results. 

General and administrative. Our general and administrative expenses increased by $0.2$4.0 million to $13.2$17.2 million,, or an increase of 2%30%, for the three months ended June 30, 2016,2017, as compared to $13.0 million for the three months ended June 30, 2015. This increase is primarily attributable to increased payroll and related expenses associated with additional employees joining the Company between the respective periods. General and administrative expenses also included non-cash stock-based compensation expense of $3.3 million and $2.8$13.2 million for the three months ended June 30, 2016 and 2015, respectively.2016. The decreaseincrease in our general and administrative expenses was attributable to the $3.7 million increase in non-cash stock-based compensation expense to $7.0 million for the three months ended June 30, 2017, as compared to $3.3 million for the three months ended June 30, 2016. The increase in our general and administrative expenses was also attributable to increased payroll expenses of approximately $1.4 million associated with additional employees joining the Company to support our increased land, geoscience, drilling, completion, production, midstream, accounting and administration functions as a result of the continued growth of the Company. The increase in our non-cash stock-based compensation was attributable to the increased expense related to the continued vesting of awards granted from 2013 through 2017 and the granting of new awards during the second quarter of 2017, as well as a change in the vesting schedule applicable to equity awards granted to our board of directors resulting in a $1.5 million one-time stock-based compensation expense. These increases were partially offset by the increase in capitalized general and administrative expense of $1.3 million due to our increased delineation and development activities in the Delaware Basin for the three months ended June 30, 2017, as compared to the three months ended June 30, 2016. As a result, our general and administrative expenses decreased 1% on a unit-of-production basis to $5.18$5.11 per BOE for the three months ended June 30, 2016,2017, as compared to $5.35$5.18 per BOE for the three months ended June 30, 2015, was also attributable to the 5% increase in total oil equivalent production between the respective periods.2016.
Net gain (loss) on asset sales and inventory impairment. Interest expense.For the three months ended June 30, 2016,2017, we recognized $1.0incurred total interest expense of approximately $11.1 million. We capitalized approximately $1.9 million of our interest expense on certain qualifying projects for the deferred gain onthree months ended June 30, 2017 and expensed the sale of certain natural gas gathering and processing assets in Loving County, Texas that occurred in the fourth quarter of 2015.
Interest expense.remaining $9.2 million to operations. For the three months ended June 30, 2016, we incurred total interest expense of approximately $7.9 million. We capitalized $1.7 million of our interest expense on certain qualifying projects for the three months ended June 30, 2016 and expensed the remaining $6.2 million. For the three months ended June 30, 2015, we incurred total interest expense of $7.2 million. We capitalized $1.3 million of our interest expense on certain qualifying projects for the three months ended June 30, 2015 and expensed the remaining $5.9 million to operations. The increase in total interest expense isof $3.3 million for the three months ended June 30, 2017, as compared to the three months ended June 30,

2016, was attributable to an increase in the average effective interest rate between comparable periods due to the issuancedebt outstanding. At June 30, 2017, we had no borrowings outstanding and $0.8 million in letters of our 6.875% senior notes due 2023 (the “Notes”) in April 2015. In late April 2015, we used a portion of the net proceeds from the issuance of the Notes and our April 2015 equity offering to repay allcredit outstanding borrowings under our Third Amended and Restated Revolving Credit Agreementrevolving credit agreement (the “Credit Agreement”), which had an effective interest rate of 2.9% for the three months ended June 30, 2015. and $575.0 million in outstanding senior notes. At June 30, 2016, we had no borrowings outstanding and $0.6 million in letters of credit outstanding under our Credit Agreement and $400.0 million in outstanding Notes.senior notes.
Total income tax benefit. Our deferred tax assets exceedexceeded our deferred tax liabilities at June 30, 2017 due to the deferred tax assetsamounts generated by the full-cost ceiling impairment charges recorded; asrecorded in prior periods. As a result, we established a valuation allowance against most of the deferred tax assets beginning in the third quarter of 2015. We retainretained a full valuation allowance at June 30, 20162017 due to uncertainties regarding the future realization of our deferred tax assets. Total income tax expense for the three months ended June 30, 2015 differed from amounts computed by applying the U.S. federal statutory tax rate to loss before income taxes due primarily to state tax apportionments and nondeductible expenses.
Six Months Ended June 30, 20162017 as Compared to Six Months Ended June 30, 20152016
Production taxes, transportation and marketing.processing. Our production taxes, transportation and marketingprocessing expenses increased by approximately $1.2$6.2 million to approximately $18.5$24.7 million, or an increase of approximately 7%34%, for the six months ended June 30, 2016,2017, as compared to $17.3$18.5 million for the six months ended June 30, 2015, in part due to our increased oil and natural gas production between the respective periods.2016. On a unit-of-production basis, our production taxes, transportation and marketingprocessing expenses increased by 3%remained consistent at $3.90 per BOE for the six months ended June 30, 2017, as compared to $3.91 per BOE for the six months ended June 30, 2016, as compared2016. The increase in production taxes, transportation and processing expenses was primarily attributable to $3.81 per BOEthe $8.0 million increase in our production taxes to $14.1 million for the six months ended June 30, 2015. The2017, as compared to $6.1 million for the six months ended June 30, 2016, primarily due to the $115.3 million increase in oil and natural gas revenues for the six months ended June 30, 2017, as compared to the six months ended June 30, 2016. In addition, the production tax rates in New Mexico are higher than production tax rates in Texas. As more of our oil and natural gas production becomes attributable to New Mexico, we expect to continue to experience increased production tax expenses. The increased production taxes were partially offset by a decrease in transportation and marketingprocessing expenses. Transportation and processing expenses on an absolute basis was primarily attributabledecreased to higher natural gas marketing$10.6 million for the six months ended June 30, 2017, as compared to transportation and processing expenses of $12.4 million for the six months ended June 30, 2016, as compared to natural gas marketing expenses2016. This decrease of $10.5$1.8 million for the three months ended June 30, 2015,was primarily due to the 8% increasestart-up in late August 2016 of the Black River Processing Plant, which processes most of the natural gas produced in our Rustler Breaks asset area in Eddy County, New Mexico, and the 36% decrease in natural gas production to 14.7 Bcf duringbetween the six months ended June 30, 2016, as compared to 13.6 Bcf of natural gas productiontwo periods in Northwest Louisiana and East Texas where our transportation and processing charges are highest on a unit-of-production basis. On a unit-of-production basis, the expenses for the six months ended June 30, 2015. 2017 also benefited from significantly higher total oil equivalent production, which increased 34% in the six months ended June 30, 2017, as compared to the six months ended June 30, 2016.
Lease operating. Our production taxes decreasedlease operating expenses increased by $5.1 million to $31.8 million, or 19%, for the six months ended June 30, 2016 by $0.7 million to $6.1 million,2017, as compared to $6.8$26.7 million for the six months ended June 30, 2015, primarily due to the 26% decrease in oil revenues during the six months ended June 30, 2016, as compared to the three months ended June 30, 2015.
Lease operating expenses. 2016. Our lease operating expenses increased by approximately $0.7 million, or an increase of 2%,unit-of-production basis decreased 11% to $28.7 million for the six months ended June 30, 2016, as compared to $28.0 million for the six months ended June 30, 2015. Our lease operating expenses per unit of production decreased 2% to $6.07$5.02 per BOE for the six months ended June 30, 2016,2017, as compared to $6.17$5.66 per BOE for the six months ended June 30, 2015. Between these respective periods, our total oil equivalent production increased approximately 4% to 4.72 million BOE from 4.54 million BOE.2016. The decrease achieved in lease operating expenses on a unit-of-production basis was primarily attributable to several key factors, including (i) decreased costs associated with our Eagle Ford operations, including workover, salt water disposal and chemical costs, (ii) additional salt water disposal and gathering capacity added in both the Wolf and Rustler Breaks asset areas and (iii) increased oil equivalent production as compared to the same periodsix months ended June 30, 2016. This decrease was partially offset by increased workover expenses in 2015.the Wolf asset area during the six months ended June 30, 2017.
Plant and other midstream services operating. Our plant and other midstream services operating expenses increased by $3.2 million to $5.3 million, an increase of 153%, for the six months ended June 30, 2017, as compared to $2.1 million for the six months ended June 30, 2016. This increase was partially attributable to the expenses associated with our salt water disposal operations of $3.0 million for the six months ended June 30, 2017, as compared to $1.6 million for the six months ended June 30, 2016, as a result of additional salt water disposal wells operating in the second quarter of 2017. The remaining increase was attributable to expenses of $1.8 million associated with the Black River Processing Plant, which began operating in August 2016.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses decreasedincreased by $38.1$15.1 million to $60.2$75.3 million, or a decrease of 39%25%, for the six months ended June 30, 2016,2017, as compared to $98.2$60.2 million for the six months ended June 30, 2015.2016. On a unit-of-production basis, our depletion, depreciation and amortization expenses decreased 7% to $11.89 per BOE for the six months ended June 30, 2017, as compared to $12.75 per BOE for the six months ended June 30, 2016. The increase in our total depletion, depreciation and amortization expenses was primarily attributable to (i) increased well costs, largely as a result of increased well stimulation costs, since December 31, 2016, or a decrease of about 41%, from $21.65 perand (ii) the 34% increase in oil and natural gas production to 6.3 million BOE for the six months ended June 30, 2015.2017, as compared to 4.7 million BOE for the six months ended June 30, 2016. The decrease in both the total and the per-unit-of-productionour depletion, depreciation and amortization expenses resulted fromon a unit-of-production basis was attributable to (i) the impairment charges recorded in 2016 and (ii) higher estimatedtotal proved reserves of 134.4 million BOE, or an increase of 41%, at June 30, 2017, as compared to total proved reserves of 95.5 million BOE or a 10% increase, at June 30, 2016, as compared to estimated total proved reserves of 87.0 million BOE at June 30, 2015, as well as the decrease in unamortized

property costs resulting from the full-cost ceiling impairments previously recorded in 2015 and 2016. ThisThe increase in total proved oil and natural gas reserves was primarily attributable to the continued delineation and development of our acreage in the Delaware Basin. In addition, depreciation expenses attributable to our midstream segment were approximately $2.5 million for the six months ended June 30, 2017, as compared to $1.0 million for the six months ended June 30, 2016.

Full-cost ceiling impairment. At June 30, 2016,2017, we recorded no impairment charge to the net capitalized costs of our oil and natural gas properties exceeded the cost center ceiling by $78.2 million. At March 31, 2016, the net capitalized costs of our oil and natural gas properties less related deferred income taxes exceeded the cost center ceiling by $80.5 million. As a result, weproperties. We recorded an impairment charge of $158.6 million to the net capitalized costs of our oil and natural gas properties for the six months ended June 30, 2016. At March 31, 2015, the net capitalized costs of our oil and natural gas properties less related deferred income taxes exceeded the cost center ceiling by $67.1 million. At June 30, 2015, the net capitalized costs of our oil and natural gas properties less related deferred income taxes exceeded the cost center ceiling by $229.0 million. As a result, we recorded an impairment charge of $296.2 million to the net capitalized costs of our oil and natural gas properties for the six months ended June 30, 2015.
General and administrative. Our general and administrative expenses remained flat at $26.4increased $7.2 million to $33.5 million, an increase of 27%, for both the six months ended June 30, 2016 and 2015. On a unit-of-production basis,2017, as compared to $26.4 million for the six months ended June 30, 2016. The increase in our general and administrative expenses was attributable to the $5.6 million increase in non-cash stock-based compensation expense to $11.2 million for the six months ended June 30, 2017, as compared to $5.6 million for the six months ended June 30, 2016. The increase in our non-cash stock-based compensation was attributable to the increased expense related to the vesting of awards granted from 2013 through 2017 and the granting of new awards during the second quarter of 2017, as well as a change in the vesting schedule applicable to equity awards granted to our board of directors resulting in a $1.5 million one-time stock-based compensation expense. The increase in our general and administrative expenses was also attributable to transaction costs of approximately $3.5 million related to the formation of San Mateo and increased payroll expenses of approximately $4.0 million associated with additional employees joining the Company to support our increased land, geoscience, drilling, completion, production, midstream, accounting and administration functions as a result of the continued growth of the Company. These increases were partially offset by the increase in capitalized general and administrative expenses of $4.9 million due to our increased delineation and development activities in the Delaware Basin for the six months ended June 30, 2017, as compared to the six months ended June 30, 2016. Our general and administrative expenses decreased by 4%5% on a unit-of-production basis to $5.29 per BOE for the six months ended June 30, 2017, as compared to $5.58 per BOE for the six months ended June 30, 2016, as comparedprimarily due to $5.81 per BOE for the six months ended June 30, 2015, as a result of our increased total oil equivalent production between the respective periods.production.
Net gain (loss) on asset sales and inventory impairment.Interest expense. For the six months ended June 30, 2016,2017, we recognized $2.1incurred total interest expense of approximately $20.8 million. We capitalized approximately $3.2 million of our interest expense on certain qualifying projects for the deferred gain onsix months ended June 30, 2017 and expensed the sale of certain natural gas gathering and processing assets in Loving County, Texas that occurred in the fourth quarter of 2015.
Interest expense. remaining $17.7 million to operations. For the six months ended June 30, 2016, we incurred total interest expense of approximately $15.6 million. We capitalized approximately $2.2 million of our interest expense on certain qualifying projects for the six months ended June 30, 2016 and expensed the remaining $13.4 million. For the six months ended June 30, 2015, we incurredmillion to operations. The increase in total interest expense of approximately $10.2 million.

The increase in total interest expensesix months ended June 30, 2016, was attributable to an increase in the average effective interest rate between comparable periods due to the issuancedebt outstanding. At June 30, 2017, we had no borrowings outstanding and $0.8 million in letters of the Notes in April 2015. In late April 2015, we used a portion of the net proceeds from the issuance of the Notes and our April 2015 equity offering to repay allcredit outstanding borrowings under our Credit Agreement.Agreement and $575.0 million in outstanding senior notes.

Total income tax expense for the six months ended June 30, 2015 differed from amounts computed by applying the U.S. federal statutory tax rates to pre-tax income due primarily to state tax apportionments and nondeductible expenses.
Liquidity and Capital Resources
Our primary use of capital has been, and we expect will continue to be during the remainder of 20162017 and for the foreseeable future, for the acquisition, exploration and development of oil and natural gas properties and for related midstream investments. Excluding any possible significant acquisitions, we expect to fund our capital expenditure requirements through the remainder of 2016 and into 2017 throughwith a combination of cash on hand (including proceeds we received in connection with the proceeds from our March 2016 equity offering,formation of the Joint Venture), operating cash flows and borrowings under our Credit Agreement (assuming availability under our borrowing base). We continually evaluate other capital sources, including borrowings under additional credit arrangements, potential joint ventures, the sale or joint venture of midstream assets or otheroil and natural gas producing assets or acreage, andparticularly in our non-core asset areas, as well as potential issuances of equity, debt or convertible securities, none of which may be available.available on satisfactory terms or at all. Our future success in growing proved reserves and production will be highly dependent on our ability to access outside sources of capital and to generate operating cash flows.
On February 17, 2017, we announced the formation of San Mateo, a strategic joint venture with Five Point to operate and expand our Delaware Basin midstream assets. We received $171.5 million in connection with the formation of the Joint Venture and may earn up to an additional $73.5 million in performance incentives over the next five years. We continue to operate the Delaware Basin midstream assets and retain operational control of the Joint Venture. The Company and Five Point own 51% and 49% of the Joint Venture, respectively. San Mateo will continue to provide firm capacity service to us at market rates, while also being a midstream service provider to third parties in and around our Wolf and Rustler Breaks asset areas.
We expect that development of our Delaware Basin assets will be the primary focus of our operations and capital expenditures for the remainder of 2017. We operated five contracted drilling rigs in the Delaware Basin and one contracted drilling rig in the Eagle Ford during the second quarter of 2017. Our 2017 estimated capital expenditure budget consists of $400 to $420 million for drilling, completions, facilities and infrastructure and $56 to $64 million for midstream capital expenditures, which represents our 51% share of an estimated 2017 capital expenditure budget of $110 to $125 million for San Mateo. We

have allocated substantially all of our estimated 2017 capital expenditures to the further delineation and development of our growing leasehold position and midstream assets in the Delaware Basin, with the exception of amounts allocated to limited operations in the Eagle Ford (including the five wells drilled and completed in 2017) and Haynesville shales to maintain and extend leases and to participate in certain non-operated well opportunities. For the remainder of 2017, our Delaware Basin drilling program will continue to focus on the development of the Wolf and Rustler Breaks asset areas and the further delineation and development of the Jackson Trust, Ranger/Arrowhead, Antelope Ridge and Twin Lakes asset areas, although we may also continue to delineate previously untested zones in the Wolf and Rustler Breaks asset areas.
During the second quarter of 2017 and through August 2, 2017, we acquired approximately 8,300 net acres in the Delaware Basin, mostly in and around our existing acreage positions, including new leasing activities, acquisitions of small interests from mineral and working interest owners in our operated wells and acreage trades or term assignments with other operators. We incurred capital expenditures of approximately $28.0 million to acquire this additional acreage throughout the Delaware Basin, as well as for new 3-D seismic data across portions of our Wolf asset area. At August 2, 2017, we held approximately 189,500 gross (108,000 net) acres in the Permian Basin in Southeast New Mexico and West Texas, primarily in the Delaware Basin in Lea and Eddy Counties, New Mexico and Loving County, Texas.
We plan to continue our leasing and acquisitions efforts in the Delaware Basin during the remainder of 2017 and may also continue acquiring acreage in the Eagle Ford and Haynesville shales. These expenditures are opportunity-specific and per-acre prices can vary significantly based on the opportunity. As a result, it is difficult to estimate these 2017 capital expenditures with any degree of certainty; therefore, we have not provided estimated capital expenditures related to acreage and mineral acquisitions for the remainder of 2017.
At June 30, 2016,2017, we had cash totaling $40.9approximately $131.5 million and restricted cash totaling approximately $15.0 million, most of which is associated with San Mateo. By contractual agreement, the borrowing basecash in the accounts held by our less-than-wholly-owned subsidiaries is not to be commingled with other Company cash and is to be used only to fund the capital expenditures and operations of these less-than-wholly-owned subsidiaries.

At June 30, 2016 and August 3, 2016, we had no borrowings outstanding, $0.6which has a borrowing base of $450.0 million and $0.8 million in outstanding lettersan elected commitment of credit pursuant to our Credit Agreement, respectively, and $400.0 million of outstanding Notes.million.
As of August 3, 2016, we anticipated investing approximately $325.0 million in capital for acquisition, exploration and development activities in 2016. We incurred total capital expenditures of approximately $198.0 million during the first six months of 2016, which was in line with our budgeted capital expenditures of $192.0 million. Our 20162017 capital expenditures may be adjusted as business conditions warrant as evidenced by the substantial reduction in our 2016 capital expenditure budget, as compared to our 2015 capital spending. While we have budgeted $325.0 million in capital expenditures for 2016,and the amount, timing and allocation of our capitalsuch expenditures is largely discretionary and within our control.
The aggregate amount of capital we will expend may fluctuate materially based on market conditions, the actual costs to drill, complete and place on production operated or non-operated wells, our drilling results, the actual costs and scope of our midstream

activities, including the expansion of the Black River Processing Plant, the ability of our Joint Venture partner to meet its capital obligations, other opportunities that may become available to us and our ability to obtain capital. When oil or natural gas prices decline, as oil and natural gas prices have done since mid-2014, or costs increase significantly, we have the flexibility to defer a significant portion of our capital expenditures until later periods to conserve cash or to focus on projects that we believe have the highest expected returns and potential to generate near-term cash flows. We routinely monitor and adjust our capital expenditures in response to changes in prices, availability of financing, drilling, completion and acquisition costs, industry conditions, the timing of regulatory approvals, the availability of rigs, success or lack of success in our exploration and development activities, contractual obligations, drilling plans for properties we do not operate and other factors both within and outside our control.
Exploration and development activities are subject to a number of risks and uncertainties, which could cause these activities to be less successful than we anticipate. A significant portion of our anticipated cash flows from operations for the remainder of 20162017 is expected to come from producing wells and development activities on currently proved properties in the Wolfcamp and Bone Spring plays in the Delaware Basin, the Eagle Ford shale in South Texas and the Haynesville shale in Northwest Louisiana. Our existing wells may not produce at the levels we are forecasting and our exploration and development activities in these areas may not be as successful as we anticipate. Additionally, our anticipated cash flows from operations are based upon current expectations of oil and natural gas prices for the remainder of 20162017 and the hedges we currently have in place. We use commodity derivative financial instruments at times to mitigate our exposure to fluctuations in oil, natural gas and natural gas liquids prices and to partially offset reductions in our cash flows from operations resulting from declines in commodity prices. AtAs of August 3, 2016,2, 2017, we had approximately 50%65% of our anticipated oil production and approximately 55%70% of our anticipated natural gas production hedged for the remainder of 2016.2017. See Note 8 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our open derivative financial instruments at June 30, 2016.2017.

(1)Adjusted EBITDA is a non-GAAP financial measure. For a definition of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to our net income (loss) and net cash provided by operating activities, see “— Non-GAAP Financial Measures” below.
Cash Flows Provided by Operating Activities
Net cash provided by operating activities decreased by $63.8increased $71.6 million to $49.6$121.2 million for the six months ended June 30, 2016, as compared to net cash provided by operating activities of $113.42017 from $49.6 million for the six months ended June 30, 2015.2016. Excluding changes in operating assets and liabilities, net cash provided by operating activities decreased by $65.5increased to $130.9 million to $43.5 million for the six months ended June 30, 20162017 from $109.0$43.5 million for the six months ended June 30, 2015.2016. This decrease isincrease was primarily attributable to the 25% decrease in ourhigher oil and natural gas revenues betweenproduction and higher commodity prices and was partially offset by the respective periods.decrease in our realized gains on derivatives and an increase in certain expenses. Changes in our operating assets and liabilities between the six months ended June 30, 2015 and the six months ended June 30, 2016two periods resulted in a net increasedecrease of $1.7approximately $15.8 million in net cash provided by operating activities for the six months ended June 30, 2017, as compared to the six months ended June 30, 2016.
Our operating cash flows are sensitive to a number of variables, including changes in our production and volatility of oil and natural gas prices between reporting periods. Regional and worldwide economic activity, the actions of OPEC, weather, infrastructure capacity to reach markets and other variable factors significantly impact the prices of oil and natural gas. These factors are beyond our control and are difficult to predict. We use commodity derivative financial instruments to mitigate our exposure to fluctuations in oil, natural gas and natural gas liquids prices. In addition, we attempt to avoid long-term service agreements where possible in order to minimize ongoing future commitments.
Cash Flows Used in Investing Activities
Net cash used in investing activities decreasedincreased by $128.0$217.4 million to $383.5 million for the six months ended June 30, 2017 from $166.0 million for the six months ended June 30, 2016 from $294.02016. This increase in net cash used in investing activities is primarily due to an increase of $166.5 million in oil and natural gas properties capital expenditures for the six months ended June 30, 2015. This decrease in net cash used in investing activities for the six months ended June 30, 2016,2017, as compared to the six months ended June 30, 2015, is primarily attributable to the following factors: (i) a decrease of $74.6 million in oil and natural gas properties capital expenditures due to our reduced 2016 capital expenditure budget, (ii) a $23.7 million decrease in cash used as a result of expenditures incurred in 2015 in connection with

our merger with Harvey E. Yates Company (the “HEYCO Merger”) and (iii) a decrease in restricted cash of $44.3 million primarily attributable to the return of cash from the escrow account established to facilitate potential like-kind exchange transactions associated with the sale of certain midstream assets in Loving County, Texas in the fourth quarter of 2015. This decrease was partially offset by the $14.7 million increase in cash used primarily for our midstream investments, including for the construction and installation of the natural gas processing plant and natural gas gathering system in the Rustler Breaks prospect area in Eddy County, New Mexico.2016. Cash used for oil and natural gas properties capital expenditures for the six months ended June 30, 20162017 was primarily attributable to our operated drilling and completion activities and the acquisition of additional leasehold and mineral interests and our operated drilling and completion activities in the Delaware Basin. A small portion of our capital expenditures for the six months ended June 30, 20162017 was directed to our participation in non-operated wells primarilyand our operated drilling and completion activities in the Delaware BasinEagle Ford shale. Additionally, there was an increase in cash outflows related to restricted cash of approximately $57.7 million between the two periods. These increases were partially offset by a decrease in cash used for other property and the Haynesville shale.equipment of approximately $5.8 million.
Cash Flows Provided by Financing Activities
Net cash provided by financing activities decreasedincreased by $85.2$40.2 million to $180.8 million for the six months ended June 30, 2017 from $140.6 million for the six months ended June 30, 2016 from $225.8 million2016. The increase in net cash provided by financing activities for the six months ended June 30, 2015.2017 was primarily attributable to (i) the increase of $171.5 million related to contributions from the formation of the Joint Venture and (ii) the net increase of $12.7 million related to contributions from and distributions to the non-controlling interest owners of less-than-wholly-owned subsidiaries, which were offset by (x) an increase in cash outflows of $2.7 million related to the purchase of the non-controlling interest of a less-than-wholly-owned subsidiary and (y) an increase in cash outflows of $2.0 million related to taxes paid in connection with the net share settlement of stock-based compensation. The net cash provided by financing activities for the six months ended June 30, 2016 was primarily attributable to the net proceeds from our March 2016 equity offering of $142.4 million ($141.5141.6 million including cost to issue equity). The net cash provided by financing activities for the six months ended June 30, 2015 was primarily attributable to the net proceeds from our April 2015 Notes offering of approximately $391.0 million, the net proceeds from our April 2015 equity offering of $187.5 million and proceeds from borrowings under the Credit Agreement of $125.0 million. These net proceeds were partially offset by (i) the $477.0 million repayment of the borrowings outstanding under our Credit Agreement and debt obligations assumed in the HEYCO Merger and (ii) the taxes paid on net share settlement of stock-based compensation of $1.6 million.
See Note 5 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our debt, including our Credit Agreement and the Notes.senior notes.

Non-GAAP Financial Measures
We define Adjusted EBITDA as earnings before interest expense, income taxes, depletion, depreciation and amortization, accretion of asset retirement obligations, property impairments, unrealized derivative gains and losses, certain other non-cash items and non-cash stock-based compensation expense, and net gain or loss on asset sales and inventory impairment. Adjusted EBITDA is not a measure of net income (loss) or cash flows as determined by GAAP. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.
Management believes Adjusted EBITDA is necessary because it allows us to evaluate our operating performance and compare the results of operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in calculating Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which certain assets were acquired.
Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income or cash flows from operating activities as determined in accordance with GAAP or as ana primary indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDA are significant components of understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure. Our Adjusted EBITDA may not be comparable to similarly titled measures of another company because all companies may not calculate Adjusted EBITDA in the same manner.

The following table presents our calculation of Adjusted EBITDA and the reconciliation of Adjusted EBITDA to the GAAP financial measures of net lossincome (loss) and net cash provided by operating activities, respectively.

General Outlook and Trends
For the three months ended June 30, 2016,2017, oil prices rangedaveraged $48.15 per Bbl, ranging from a high of $53.40 per Bbl in mid-April to a low of approximately $35.70$42.53 per Bbl in early April to a high of approximately $51.23 per Bbl in earlylate June, based upon the NYMEX West Texas Intermediate oil futures contract price for the earliest delivery date. We realized an average oil price of $42.84$46.01 per Bbl ($43.2946.34 per Bbl including realized gains from oil derivatives) for our oil production for the three months ended June 30, 2016,2017, as compared to $54.37$42.84 per Bbl ($62.72

43.29 per Bbl including realized gains from oil derivatives) for the three months ended June 30, 2015. Subsequent to June 30, 2016, oil prices have decreased and, at2016. At August 3, 2016,2, 2017, the NYMEX West Texas Intermediate oil futures contract for the earliest delivery date closedhad increased from the weighted average price for the second quarter of 2017, settling at $40.83$49.59 per Bbl, which was also an increase as compared to $45.17$39.51 per Bbl at August 3, 2015.2, 2016.
For the three months ended June 30, 2016,2017, natural gas prices rangedaveraged $3.14 per MMBtu, ranging from a high of $2.92approximately $3.42 per MMBtu in mid-May to a low of approximately $2.89 per MMBtu in late June, to a low of $1.90 per MMBtu in mid-April, based upon the NYMEX Henry Hub natural gas futures contract price for the earliest delivery date. We realized a weighted average natural gas price of $3.40 per Mcf ($3.39 per Mcf including realized losses from natural gas derivatives) for our natural gas production (including revenues attributable to natural gas liquids) for the three months ended June 30, 2017, as compared to $2.10 per Mcf ($2.34 per Mcf including realized gains from natural gas derivatives) for our natural gas production for the three months ended June 30, 2016, as compared to $2.78 per Mcf ($3.24 per Mcf including aggregate realized gains from natural gas and NGL derivatives) for the three months ended June 30, 2015. Because we report our production volumes in two streams, oil and natural gas, including dry and liquids-rich natural gas, revenues associated with extracted natural gas liquids are included with our natural gas revenues, which has the effect of increasing the weighted average natural gas price realized on a per Mcf basis. Since June 30, 2016, natural gas prices have remained relatively stable, and at2016. At August 3, 2016,2, 2017, the NYMEX Henry Hub natural gas futures contract for the earliest delivery date closedhad decreased from the weighted average price for the second quarter of 2017, settling at $2.84$2.81 per MMBtu, which was a small increase as compared to $2.75$2.73 per MMBtu at August 3, 2015.2, 2016.
The prices we receive for oil, natural gas and natural gas liquids heavily influence our revenue, profitability, cash flow available for capital expenditures, access to capital and future rate of growth. Oil, natural gas and natural gas liquids are commodities, and therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil, natural gas and natural gas liquids have been volatile and these markets will likely continue to be volatile in the future. Declines in oil, natural gas or natural gas liquids prices not only reduce our revenues, but could also reduce the amount of oil, natural gas and natural gas liquids we can produce economically. We are uncertain when, or if oil and natural gas prices may rise from their current levels, and in fact, oil and natural gas prices may decrease again in future periods.
From time to time, we use derivative financial instruments to mitigate our exposure to commodity price risk associated with oil, natural gas and natural gas liquids prices. Even so, decisions as to whether, at what price and what production volumes to hedge are difficult and depend on market conditions and our forecast of future production and oil, natural gas and natural gas liquids prices, and we may not always employ the optimal hedging strategy. This, in turn, may affect the liquidity that can be accessed through the borrowing base under our Credit Agreement and through the capital markets. We expect our realized gains from derivatives to be less for
Coinciding with the remainderrecent improvements in oil and natural gas prices since the latter part of 2016, as comparedwe have begun to comparable periods in 2015, especiallyexperience price increases from our service providers for some of the products and services we use in our drilling, completion and production operations. If oil derivative contracts.and natural gas prices remain at their current levels for a longer period of time or should they increase further, we could experience additional price increases for drilling, completion and production products and services, although we can provide no estimates as to the eventual magnitude of these increases.
Like other oil and natural gas producing companies, our properties are subject to natural production declines. By their nature, our oil and natural gas wells will experience rapid initial production declines. We attempt to overcome these production declines by drilling to develop and identify additional reserves, by exploring for new sources of reserves and, at times, by acquisitions. During times of severe oil, natural gas and natural gas liquids price declines, however, drilling additionalcertain oil or natural gas wells may not be economical, and we may find it necessary to reduce capital expenditures and curtail drilling operations in order to preserve liquidity. A material reduction in capital expenditures and drilling activities could materially impact our production volumes, revenues, reserves, cash flows and our availability under our Credit Agreement.
We strive to focus our efforts on increasing oil and natural gas reserves and production while controlling costs at a level that is appropriate for long-term operations. Our ability to find and develop sufficient quantities of oil and natural gas reserves at economical costs is critical to our long-term success. Future finding and development costs are subject to changes in the costs of acquiring, drilling and completing our prospects.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.Risk
Except as set forth below, there have been no material changes to the sources and effects of our market risk since December 31, 2015,2016, which are disclosed in Part II, Item 7A of the Annual Report.Report and incorporated herein by reference.
Commodity price exposure. We are exposed to market risk as the prices of oil, natural gas and natural gas liquids fluctuate as a result of changes in supply and demand and other factors. To partially reduce price risk caused by these market fluctuations, we have entered into derivative financial instruments in the past and expect to enter into derivative financial instruments in the future to cover a significant portion of our anticipated future production.
We typically use costless (or zero-cost) collars and/or swap contracts to manage risks related to changes in oil, natural gas and natural gas liquids prices. Costless collars provide us with downside price protection through the purchase of a put option thatwhich is financed through the sale of a call option. Because the call option proceeds are used to offset the cost of the put option, these arrangements are initially “costless” to us. In the case of a costless collar, the put option and the call option have different fixed price components. In a swap contract, a floating price is exchanged for a fixed price over a specified time,period, providing downside price protection.

We record all derivative financial instruments at fair value. The fair value of our derivative financial instruments is determined using industry-standard models that consider various inputs including: (i) quoted forward pricespurchase and sale information available for commodities, (ii) time value of money and (iii) current market and contractual prices for the underlying instruments, as well as other relevant economic measures.similarly traded securities. At June 30, 2016,2017, Comerica Bank, The Bank of Nova Scotia, BMO Harris Financing Inc. (Bank of Montreal) and SunTrust Bank (or affiliates thereof) were the counterparties for all of our derivative instruments. We have evaluatedconsidered the credit standing of the counterparties in determining the fair value of our derivative financial instruments. See Note 8 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our open derivative financial instruments at June 30, 2016.2017.
