Matador Resources Company and Subsidiaries
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS -
UNAUDITED
NOTE 1 - NATURE OF OPERATIONS
Matador Resources Company, a Texas corporation (“Matador” and, collectively with its subsidiaries, the “Company”), is an independent energy company 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. The Company’s 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. 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. Additionally, the Company conducts midstream operations, primarily through its midstream joint venture, San Mateo Midstream, LLC (“San Mateo” or the “Joint Venture”), in support of the Company’s exploration, development and production operations and provides natural gas processing, oil transportation services, oil, natural gas oil and salt water gathering services and salt water disposal services to third parties on a limited basis.parties.
NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Interim Financial Statements, Basis of Presentation, Consolidation and Significant Estimates
The interim unaudited condensed consolidated financial statements of Matador and its subsidiariesthe Company 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, 20162017 (the “Annual Report”) filed with the SEC. The Company consolidates certain subsidiaries and joint ventures that are less 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 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 whichthat are necessary for a fair presentation of the Company’s interim unaudited condensed consolidated financial statements as of June 30, 2017.March 31, 2018. Amounts as of December 31, 20162017 are derived from the Company’s audited consolidated financial statements included 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 and midstream 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.
ReclassificationsChange in Accounting Principles
Certain reclassificationsDuring the first quarter of 2018, the Company adopted Accounting Standards Codification, Revenue from Contracts with Customers (Topic 606) (“ASC 606”), which specifies how and when to recognize revenue. This 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. The Company adopted the new guidance using the modified retrospective approach. The adoption did not require an adjustment to opening accumulated deficit for any cumulative effect adjustment and does not have a material impact on the Company’s consolidated balance sheets, statements of operations, statement of shareholders’ equity or statements of cash flows.  
Prior to the adoption of ASC 606, the Company recorded oil and natural gas revenues at the time of physical transfer of such products to the purchaser. The Company followed the sales method of accounting for oil and natural gas sales, recognizing revenues based on the Company’s actual proceeds from the oil and natural gas sold to purchasers.
The Company enters into contracts with customers to sell its oil and natural gas production. Revenue on these contracts is recognized in accordance with the five-step revenue recognition model prescribed in ASC 606. Specifically, revenue is

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES — Continued

recognized when the Company’s performance obligations under these contracts are satisfied, which generally occurs with the transfer of control of the oil and natural gas to the purchaser. Control is generally considered transferred when the following criteria are met: (i) transfer of physical custody, (ii) transfer of title, (iii) transfer of risk of loss and (iv) relinquishment of any repurchase rights or other similar rights. Given the nature of the products sold, revenue is recognized at a point in time based on the amount of consideration the Company expects to receive in accordance with the price specified in the contract. Consideration under the oil and natural gas marketing contracts is typically received from the purchaser one to two months after production.
The majority of the Company’s oil marketing contracts transfer physical custody and title at or near the wellhead, which is generally when control of the oil has been transferred to the purchaser. The majority of the oil produced is sold under contracts using market-based pricing, which price is then adjusted for differentials based upon delivery location and oil quality. To the extent the differentials are incurred after the transfer of control of the oil, the differentials are included in oil sales on the statements of operations as they represent part of the transaction price of the contract. If the differentials, or other related costs, are incurred prior to the transfer of control of the oil, those costs are included in production taxes, transportation and processing expenses on the Company’s consolidated statements of operations as they represent payment for services performed outside of the contract with the customer.
The Company’s natural gas is sold at the lease location, at the inlet or outlet of a natural gas plant or at an interconnect near a marketing hub following transportation from a processing plant. The majority of the Company’s natural gas is sold under fee-based contracts. When the natural gas is sold at the lease, the purchaser gathers the natural gas and transports the natural gas via pipeline to natural gas processing plants where natural gas liquid (“NGL”) products are extracted. The NGL products and remaining residue gas are then sold by the purchaser or the Company sells the natural gas to a third party. Under the fee-based contracts, the Company receives NGL and residue gas value, less the fee component, or is invoiced the fee component. To the extent control of the natural gas transfers upstream of the transportation and processing activities, revenue is recognized as the net amount received from the purchaser. To the extent that control transfers downstream of those services, revenue is recognized on a gross basis, and the related costs are included in production taxes, transportation and processing expenses on the Company’s consolidated statements of operations.
The Company recognizes midstream services revenues at the time services have been maderendered and the price is fixed and determinable. Third-party midstream services revenues are those revenues from midstream operations related to third parties, including working interest owners in our operated wells. All midstream services revenues related to the prior periods’Company’s working interest are eliminated in consolidation. Since the Company has a right to payment from its customers in amounts that correspond directly to the value that the customer receives from the performance completed on each contract, the Company applies the practical expedient in ASC 606 that allows recognition of revenue in the amount for which there is a right to invoice the customer without estimating a transaction price for each contract and allocating that transaction price to the performance obligations within each contract.
The Company determined the impact to its consolidated financial statements to conform to the current period presentation. Asas a result of the growthadoption of the Company’s midstream operations, these operations met the required threshold for segment reporting. Asthis standard was a result, $0.9$2.2 million decrease in oil and natural gas revenues and a $2.2 million decrease in production taxes, transportation and processing expenses for the three months ended June 30, 2016March 31, 2018, which was not material. As a result of adoption of this standard, the Company is now required to disclose the following information regarding revenues from contracts with customers and $1.4 million for the six months ended June 30, 2016 were reclassifiedrevenues from other income to third-party midstream services revenues. In addition, $1.1 million related to midstream operating costscontracts with customers on a disaggregated basis for the three months ended June 30, 2016March 31, 2018 (in thousands).

The Company does not disclose the value of unsatisfied performance obligations under its contracts with customers as it applies the practical exemption in accordance with ASC 606. The exemption, as described in ASC 606-10-50-14(a), applies to variable consideration that is recognized as control of the product is transferred to the customer. Since each unit of product represents a separate performance obligation, future volumes are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is not required.
During the first quarter of 2018, the Company adopted Accounting Standards Update (“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. The Company adopted ASU 2016-18 effective January 1, 2018 and determined that the adoption of this ASU changed the presentation of its beginning and ending cash balances and eliminated the presentation of changes in restricted cash balances from investing activities in its consolidated statements of cash flows. The Company adopted the new guidance using the retrospective transition method; as a result, approximately $6.0 million and $1.3 million of restricted cash was added to the beginning cash balance for the sixthree months ended June 30, 2016 were reclassified from lease operating expensesMarch 31, 2018 and 2017, respectively.
During the first quarter of 2018, the Company adopted ASU 2017-01, Business Combinations (Topic 805), which specifies the minimum inputs and processes required for an integrated set of assets and activities to plant and other midstream services operating expenses. These reclassifications had no effectmeet the definition of a business. The Company adopted ASU 2017-01 prospectively, which did not have a material impact on previously reported results of operations, cash flows or retained earnings.its consolidated financial statements.
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 that 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 both the three and six months ended June 30,March 31, 2018 and 2017, the cost center ceiling was higher than the capitalized costs

of 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 recordedno 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.charge was necessary.
The Company capitalized approximately $5.2$7.3 million and $4.0$5.6 million of its general and administrative costs for the three months ended June 30,March 31, 2018 and 2017, and 2016, respectively, and approximately $1.9 million and $1.7$1.2 million of its interest expense for the three months ended June 30,March 31, 2018 and 2017, and 2016, respectively. The Company capitalized approximately $10.8 million and $6.0 million of its general and administrative costs for the six months ended June 30, 2017 and 2016, respectively, and approximately $3.2 million and $2.2 million of its interest expense for the six months ended June 30, 2017 and 2016, respectively.

Recent Accounting Pronouncements
Revenue from Contracts with Customers.In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), which specifies how and when to recognize revenue. This 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. In August 2015, the FASB issued ASU 2015-14, 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, 2016. In May 2016, the FASB issued ASU 2016-11, which rescinds guidance from the SEC on accounting for gas balancing arrangements and will eliminate the use of the entitlements method. Entities have the option of using either a full retrospective or modified approach to adopt the new standards. In December 2016, the FASB issued ASU 2016-20, which clarifies disclosure requirements in ASU 2014-09. The Company expects to adopt the new guidance effective January 1, 2018 using the modified approach. The Company is evaluating the new guidance, including (i) identification of revenue streams and (ii) review of contracts and procedures currently in place.
Leases. In February 2016, the FASBFinancial Accounting Standards Board (“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

NOTE 5 -4 — DEBT
At June 30, 2017 and August 2, 2017,March 31, 2018, the Company had $575.0 million of outstanding 6.875% senior notes due 2023, no borrowings outstanding under the Company’s revolving credit agreement (the “Credit Agreement”) and approximately $0.8$2.1 million in outstanding letters of credit issued pursuant to the Credit Agreement. At May 2, 2018, the Company had $575.0 million of outstanding 6.875% senior notes due 2023, $45.0 million in borrowings outstanding under the Credit Agreement and approximately $3.0 million in outstanding letters of credit issued pursuant to the Credit Agreement.
Credit Agreement
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. During the first quarter of 2017,2018, the lenders completed their review of the Company’s proved oil and natural gas reserves at December 31, 2016,2017, and as a result, on April 28, 2017,March 5, 2018, the borrowing base was increased to $450.0$725.0 million. This March 2018 redetermination constituted the regularly scheduled May 1 redetermination. The Company elected to keep the borrowing commitment at $400.0 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 are limited to the leastlowest of the borrowing base, the maximum facility amount and the elected commitment. The Credit Agreement matures on October 16, 2020.
In the event of an 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 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.March 31, 2018.
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 15 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 9 -8 — 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.
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, 2017March 31, 2018 and December 31, 20162017 (in thousands).

NOTE 10 -9 — COMMITMENTS AND CONTINGENCIES

Processing, Transportation and Salt Water Disposal Commitments
Eagle 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, and the revenue the Company receives 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 paid $0.5 million and $0.8 million in processing and transportation fees under this agreement during the three months ended June 30, 2017 and 2016, respectively, and $1.0 million and $1.7 million in processing and transportation fees under this agreement during the six months ended June 30, 2017 and 2016, 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 facilities. Under this agreement, if the Company does not meet the volume commitment for transportation and processing at the facilities 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 transportation 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, 2017,March 31, 2018, the total deficiency fee required to be paid would be approximately $11.6$12.6 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 $3.7$3.5 million and $2.8$3.2 million in natural gas processing and gathering fees under this agreement during the three months ended June 30,March 31, 2018 and 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 — Eddy County, New Mexico Natural Gas Transportation
In late 2017, the Company entered into an 18-year, fixed-fee natural gas transportation agreement whereby the Company committed to deliver a portion of the residue natural gas production at the tailgate of San Mateo’s Black River cryogenic natural gas processing plant in the Rustler Breaks asset area (the “Black River Processing Plant”) to transport through the counterparty’s pipeline. Under this agreement, if the Company does not meet the volume commitment for transportation in a contract year, the Company will owe the fees to transport the committed volume whether or not the committed volume is utilized. The minimum contractual obligation at March 31, 2018 was approximately $58.8 million. The Company paid approximately $0.5 million in transportation fees under this agreement during the three months ended March 31, 2018.
In late 2017, the Company also entered into a fixed-fee NGL transportation and fractionation agreement whereby the Company committed to deliver its NGL production at the tailgate of the Black River Processing Plant. The Company is committed to deliver a minimum amount of NGLs to the counterparty upon construction and completion of a pipeline expansion and a fractionation facility by the counterparty, which is currently expected to be completed late in 2019. The Company has no rights to compel the counterparty to construct this pipeline extension or fractionation facility. If the counterparty does not construct the pipeline extension and fractionation facility, then the Company does not have any minimum volume commitments under the agreement. If the counterparty constructs the pipeline extension and fractionation facility on or prior to February 28, 2021, then the Company will have a commitment to deliver a minimum amount of NGLs for seven years following the completion of the pipeline extension and fractionation facility. If the Company does not meet its NGL volume commitment in any quarter during the seven-year commitment period, it will be required to pay a deficiency fee per gallon of NGL deficiency. Should the pipeline extension and fractionation facility be completed on or prior to February 28, 2021, the minimum contractual obligation during the seven-year period would be approximately $132.5 million.

For the secondfirst quarter of 2017,2018, we reported net income attributable to Matador Resources Company shareholders of approximately $28.5$59.9 million, or $0.28$0.55 per diluted common share on a GAAP basis, as compared to a net lossincome attributable to Matador Resources Company shareholders of $105.9$44.0 million, or $1.15$0.44 per diluted common share, for the secondfirst quarter of 2016.2017. For the secondfirst quarter of 2017,2018, our Adjusted EBITDA attributable to Matador Resources Company shareholders (“Adjusted EBITDA”), a non-GAAP financial measure, was $72.7$117.3 million, as compared to Adjusted EBITDA of $38.9$70.0 million during the secondfirst 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, 2017, 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 six months ended June 30, 2016. For the six months ended June 30, 2017, our Adjusted EBITDA, a non-GAAP financial measure, was $142.6 million, as compared to Adjusted EBITDA of $56.1 million during the six months ended June 30, 2016.2017.

During the secondfirst quarter of 2017,2018, we continued 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 20172018 operating foursix 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 and2018. We expect to operate fivethose six rigs in the

Delaware Basin throughout the remainder of 2017,2018, including three rigs in ourthe Rustler Breaks and Antelope Ridgeasset area, one rig in the Wolf/Jackson Trust asset areas, one rig in our Wolfthe Ranger/Arrowhead and Jackson TrustTwin Lakes asset areas and one rig in our Ranger/Arrowhead and Twin Lakesthe Antelope Ridge 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. At June 30, 2017, we had incurred approximately $241 million, or 51%, of our 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 secondarea. San Mateo’s third commercial salt water disposal well in the Rustler Breaks asset area for San Mateo. Upon deliverybecame operational in the first quarter of 2018, and one of the sixth drilling rig,three rigs operating in the Rustler Breaks asset area is also expected to drill at least two additional commercial 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 wellwells in ourthat area during 2018 for San Mateo, which, when completed, will result in five commercial salt water disposal wells in the Rustler Breaks asset area. At August 2, 2017,Depending on commodity prices, costs, opportunities in new asset areas like Antelope Ridge, liquidity and other factors, we had no plans to use this sixthmay consider adding a seventh rig to drill additional oil andtowards the end of 2018.
In late March 2018, we completed the expansion of San Mateo’s Black River cryogenic natural gas wells forprocessing plant in the remainderRustler Breaks asset area in Eddy County, New Mexico (the “Black River Processing Plant”), adding an incremental designed inlet capacity of 2017.200 MMcf of natural gas per day and bringing the total designed inlet capacity of the Black River Processing Plant to 260 MMcf of natural gas per day. The expanded Black River Processing Plant supports our exploration and development activities in the Delaware Basin, and with the expanded capacity, San Mateo can offer natural gas processing services to other producers as well.
We also finishedDuring the first quarter of 2018, we did not conduct any operated drilling and completion activities on our five-well programleasehold properties in the Eagle Ford shale play in South Texas duringor in the second quarterHaynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas, although we did participate in the drilling and completion of 2017. Two of these3 gross (0.1 net) non-operated Haynesville shale wells that 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 secondthe first quarter 2017 production volumes. The rig used to drill these five wells was released in May 2017, and weof 2018. We have no additional operated drilling activities planned in the Eagle Ford or in the Haynesville shale and Cotton Valley plays for the remainder of 2017.2018.
We completed and turned to sales a total of 2129 gross (14.2(16.1 net) wells in the Delaware Basin during the secondfirst quarter of 2017,2018, including 16 gross (13.5(13.4 net) operated horizontal wells, one gross (1.0 net) operated vertical well and five12 gross (0.7(1.7 net) non-operated horizontal wells. During the first quarter of 2018, we began producing oil and natural gas from our first three gross (3.0 net) operated wells in the Antelope Ridge asset area, including a Wolfcamp A-XY completion, a Wolfcamp A-Lower completion and a First Bone Spring completion. We also participated in two gross (0.1 net) non-operated wells in the Antelope Ridge asset area. In the Rustler Breaks asset area, we began producing oil and natural gas from a total of 1316 gross (8.2(9.1 net) wells during the secondfirst quarter of 2017,2018, including nine gross (7.6(7.8 net) operated and fourseven gross (0.6(1.3 net) non-operated wells. Of the nine gross operated wells in the Rustler Breaks asset area, fivefour were Wolfcamp A-XY completions, two were Wolfcamp A-Lower completions, two were Wolfcamp B-Blair completions and one was a Wolfcamp A-Lower completion and three were Wolfcamp B-Blair completions.vertical Morrow completion. In addition, we began producing oil and natural gas from fivetwo gross (4.2(1.0 net) operated wells in the Wolf and Jackson Trust asset areaareas during the secondfirst quarter of 2017,2018, including onea Wolfcamp A-XY completion and four Second Bone Spring completions.a Wolfcamp A-Lower completion. In the Ranger, Ranger/Arrowhead and Twin Lakes asset areas, we began producing oil and natural gas from a total of onesix gross (0.1(2.9 net) wells, including three gross (2.6 net) operated wells and three gross (0.3 net) non-operated well, one gross (0.7 net) operated well and one gross (1.0 net) operated well, respectively,wells during the secondfirst quarter of 2017. The well in the Arrowhead asset area, a Second Bone Spring 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.2018.
As a result of our ongoing drilling and completion operations in these asset areas, our Delaware Basin production has continued to increase over the past twelve months. Our total Delaware Basin production for the secondfirst quarter of 20172018 was 27,62237,160 BOE per day, consisting of 16,64523,363 Bbl of oil per day and 65.982.8 MMcf of natural gas per day, a 90%51% increase from production of 14,52524,535 BOE per day, consisting of 9,78915,685 Bbl of oil per day and 28.453.1 MMcf of natural gas per day, in the secondfirst quarter of 2016.2017. The Delaware Basin contributed approximately 88% of our daily oil production and approximately 73% of our daily natural gas production in the first quarter of 2018, as compared to approximately 86% of our daily oil production and approximately 63%60% of our daily natural gas production in the secondfirst quarter of 2017,2017.
Strategic Relationship with Plains
On January 22, 2018, a subsidiary of San Mateo entered into a strategic relationship with a subsidiary of Plains All American Pipeline, L.P. (“Plains”) to gather and transport crude oil for us and additional customers in and around the Rustler Breaks asset area. Subsidiaries of San Mateo and Plains have agreed to work together through a joint tariff arrangement and related transactions to offer producers located within a joint development area of approximately 400,000 acres in Eddy County, New Mexico crude oil transportation services from the wellhead to Midland, Texas with access to other end markets, such as comparedCushing and the Gulf Coast. In addition, another subsidiary of Plains has agreed to approximately 72% ofpurchase our daily oil production and approximately 33% of our daily natural gas production in the second quarter of 2016.
During the second quarter of 2017 and through August 2, 2017, we acquired approximately 8,300 net acresRustler Breaks asset area 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 SoutheastEddy County, New Mexico and West Texas, primarilythe Wolf asset area 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 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, 2017, December 31, 2016 and June 30, 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. 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, 2017, December 31, 2016 and June 30, 2016 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, 2017, December 31, 2016 and June 30, 2016 were $85.0 million, $6.5 million and $4.9 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, including 52.3 million Bbl of oil and 258.7 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. At June 30, 2017, approximately 41% of our total proved reserves were proved developed reserves, 56% of our total proved reserves were oil and 44% of our total proved reserves were natural gas.
As a result of our drilling, completion and delineation activities in Southeast New Mexico and West Texas since 2014, our Delaware Basin oil and natural gas reserves have become a more significant component of our total oil and natural gas reserves. Our estimated Delaware Basin proved oil and natural gas reserves increased 63% from 66.2 million BOE at June 30, 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, 2017.

Three Months Ended June 30, 2017March 31, 2018 as Compared to Three Months Ended June 30, 2016March 31, 2017
Oil and natural gas revenuesrevenues. . Our oil and natural gas revenues increased $44.4$67.1 million to $113.8$182.0 million, or 64%58%, for the three months ended June 30, 2017,March 31, 2018, as compared to $69.3$114.8 million for the three months ended June 30, 2016.March 31, 2017. Our oil revenues increased $28.6$64.5 million, or 54%77%, to $81.3148.2 million for the three months ended June 30, 2017March 31, 2018, as compared to $52.783.6 million for the three months ended June 30, 2016March 31, 2017. The increase in oil revenues resulted from (i) a higher weighted average oil price realized for the three months ended June 30, 2017March 31, 2018 of $46.01$62.20 per Bbl, as compared to $42.84$50.72 per Bbl realized for the three months ended June 30, 2016,March 31, 2017, and (ii) the 44% increase in our oil production to 1.772.4 million Bbl of oil for the three months ended June 30, 2017,March 31, 2018, or about 19,42326,465 Bbl of oil per day, as compared to 1.231.6 million Bbl of oil, or about 13,51618,323 Bbl of oil per day, for the three months ended June 30, 2016.March 31, 2017. The increase in oil production iswas primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin. Our natural gas revenues increased by $15.8$2.6 million, or 95%8%, to $32.4$33.8 million for the three months ended June 30, 2017,March 31, 2018, as compared to $16.6$31.2 million for the three months ended June 30, 2016.March 31, 2017. The increase in natural gas revenues resulted from (i)the 28% increase in our natural gas production to 10.2 Bcf for the three months ended March 31, 2018, as compared to 7.9 Bcf for the three months ended March 31, 2017, which was partially offset by a higherlower weighted average natural gas price realized for the three months ended June 30, 2017March 31, 2018 of $3.40$3.33 per Mcf, as compared to $2.10$3.94 per Mcf realized for the three months ended June 30, 2016, and (ii) the 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.March 31, 2017. The increase in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.

Third-party midstream services revenues. Our third-party midstream services revenues increased $1.5 million to $2.1$3.1 million, or 129%97%, for the three months ended June 30, 2017,March 31, 2018, as compared to $0.9$1.6 million for the three months ended June 30, 2016.March 31, 2017. Third-party midstream services revenues are those revenues from midstream operations related to third parties, including working interest owners in our operated wells. This increase was primarily attributable to a significant increase in (i) natural gas gathering and processing revenues to approximately $1.6$1.9 million for the three months ended June 30, 2017,March 31, 2018, as compared to $1.1 million for the three months ended March 31, 2017, due to increased natural gas production in our Rustler Breaks and Wolf asset areas and (ii) an increase in our third-party salt water gathering and disposal revenue to approximately $1.1 million for the three months ended March 31, 2018, as compared to approximately $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 our Wolf asset area.March 31, 2017.
Realized gainloss on derivativesderivatives.. Our realized net gainloss on derivatives was $0.6$4.3 million for the three months ended June 30, 2017,March 31, 2018, as compared to a realized net gainloss of $2.5$2.2 million for the three months ended June 30, 2016.March 31, 2017. We realized a net gainloss of $0.6$4.3 million from our oil derivative contracts for the three months ended June 30, 2017,March 31, 2018 resulting from oil prices belowabove the floorshort call/ceiling prices of certain of our oil costless collar contracts and oil basis prices below swap prices of certain of our oil basis swap contracts. We realized a net gainsloss of $0.6$1.6 million and $1.9$0.6 million from our oil and natural gas derivative contracts, respectively, for the three months ended June 30, 2016, resulting from oil and natural gas prices 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. Our total natural gas volumes hedged for the three months ended June 30, 2017 were 109% higher than the total natural gas volumes hedged for the three months ended June 30, 2016.
Unrealized gain (loss) on derivatives. Our unrealized net gain on derivatives was $13.2 million for the three months ended June 30, 2017, as compared to an unrealized net loss of $26.6 million for the three months ended June 30, 2016. During the three months ended June 30, 2017, the aggregate net fair value of our open oil and natural gas derivative contracts increased to an asset of approximately $8.9 million from a liability of $4.3 million at March 31, 2017, resulting in an unrealized net gain on derivatives of $13.2 million for the three months ended June 30, 2017. During the three months ended June 30, 2016, the aggregate net fair value of our open oil and natural gas derivative contracts decreased to a liability of $17.2 million from an asset of $9.4 million at March 31, 2016, resulting in an unrealized loss on derivatives of $26.6 million for the three months ended June 30, 2016.
Six Months Ended June 30, 2017 as Compared to Six Months Ended June 30, 2016
Oil and natural gas revenues. Our oil and natural gas revenues increased $115.3 million to $228.6 million, or 102%, for the six months ended June 30, 2017, as compared to $113.3 million for the six months ended June 30, 2016. Our oil revenues increased $82.1 million, or 99%, to $165.0 million for the six months ended June 30, 2017, as compared to $82.8 million for the six months ended June 30, 2016. The increase in oil revenues resulted from (i) a higher weighted average oil price realized for the six months ended June 30, 2017 of $48.28 per Bbl, as compared to $36.43 per Bbl realized for the six months ended June 30, 2016, and (ii) the 50% increase in oil production to 3.42 million Bbl of oil in the six months ended June 30, 2017, or about 18,876 Bbl of oil per day, as compared to 2.27 million Bbl of oil, or about 12,495 Bbl of oil per day, in the six months ended June 30, 2016. This increased oil production is primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin. Our natural gas revenues increased by $33.2 million, or 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. The increase in natural gas revenues resulted from (i) a higher weighted average natural gas price realized for the six months ended June 30, 2017 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 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. The increase in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.
Third-party midstream services revenues. Our third-party midstream services revenues increased to $3.7 million, or 163%, for the six months ended June 30, 2017, as compared to $1.4 million for the six months ended June 30, 2016. This increase was primarily attributable to a significant increase in natural gas gathering 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, due to (i) our natural gas gathering system and 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 our Wolf asset area.
Realized gain (loss) on derivatives. Our realized net loss on derivatives was $1.7 million for the six months ended June 30, 2017, as compared to a net gain of approximately $9.5 million for the six months ended June 30, 2016. We realized net losses of $1.1 million and $0.6 million from our oil and natural gas derivative contracts, respectively, for the six months ended June 30, 2017 resulting from oil and natural gas prices that were above the ceiling prices of certain of our oil and natural gas costless collar contracts. We realized net gains of $6.0 million and $3.5 million from our oil and natural gas derivative contracts, respectively, for the six months ended June 30, 2016, resulting from oil and natural gas prices below the floor prices of the majority of our oil and natural gas costless collar contracts. We realized an average loss on our oil derivatives of approximately $0.48$1.81 per Bbl hedged on all of our open oil costless collar contractsproduced during the sixthree months ended June 30, 2017,March 31, 2018, as compared to an average gainloss of $5.11$0.99 per Bbl hedged forproduced during the sixthree months ended June 30, 2016.March 31, 2017. Our total oil volumes hedged for the three months ended June 30, 2017 were 86% higherMarch 31, 2018 represented 55% of our total oil production, as

compared to 58% of our total oil production for the sixthree months ended June 30, 2016.March 31, 2017. We realized an average loss of approximately $0.05 per MMBtu hedged on all of our open natural gas costless collar contractsderivatives of less than $0.01 per Mcf produced during the sixthree months ended June 30, 2017,March 31, 2018, as compared to an average gainloss of approximately $0.61$0.08 per MMBtu hedged on all of our open natural gas costless collar contractsMcf produced for the sixthree months ended June 30, 2016.March 31, 2017. Our total natural gas volumes hedged for the sixthree months ended June 30, 2017 were 102% higher than theMarch 31, 2018 represented 41% of our total natural gas volumes hedgedproduction, as compared to 66% of our total natural gas production for the sixthree months ended June 30, 2016.March 31, 2017.
Unrealized gain (loss) on derivatives.Our unrealized net gain on derivatives was approximately $33.8$10.4 million for the sixthree months ended June 30, 2017,March 31, 2018, as compared to an unrealized lossnet gain of approximately $33.5$20.6 million for the sixthree months ended June 30, 2016.March 31, 2017. During the period from Decemberthree months ended March 31, 2016 through June 30, 2017,2018, the aggregate net fair value of our open oil and natural gas derivative contracts increased fromchanged to a net liability of approximately $25.0$4.8 million to an assetfrom a net liability of approximately $8.9$15.2 million at December 31, 2017, resulting in an unrealized net gain on derivatives of approximately $33.8$10.4 million for the sixthree months ended June 30, 2017. This gain is primarily attributable toMarch 31, 2018. During the decrease in oil and natural gas futures prices during the sixthree months ended June 30, 2017. DuringMarch 31, 2017, the period from December 31, 2015 through June 30, 2016, the aggregate net fair value of our open oil and natural gas derivative contracts decreased from an asset of approximately $16.3 millionchanged to a net liability of approximately $17.2$4.3 million from a net liability of $25.0 million at December 31, 2016, resulting in an unrealized lossnet gain on derivatives of approximately $33.5$20.6 million for the sixthree months ended June 30, 2016.March 31, 2017.

Three Months Ended June 30, 2017March 31, 2018 as Compared to Three Months Ended June 30, 2016March 31, 2017
Production taxes, transportation and processing. Our production taxes, transportation and processing expenses increased by $2.3$6.0 million to $12.9$17.8 million, or 22%51%, for the three months ended June 30, 2017,March 31, 2018, as compared to $10.6$11.8 million for the three months ended June 30, 2016.March 31, 2017. On a unit-of-production basis, our production taxes, transportation and processing expenses increased 10% to $4.37 per BOE for the three months ended March 31, 2018, as compared to $3.98 per BOE for the three months ended March 31, 2017. The increase in production taxes, transportation and processing expenses was primarily attributable to the $5.9 million increase in our production taxes of $3.1 million to $6.9$13.1 million for the three months ended June 30, 2017,March 31, 2018, as compared to $3.9$7.2 million for the three months ended June 30, 2016,March 31, 2017, primarily due to the 64%$67.1 million increase in oil and natural gas revenues for the three months ended June 30, 2017,March 31, 2018, as compared to the three months ended June 30, 2016.March 31, 2017. 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 increasedour 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, 2017, as compared to transportation 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, asincrease proportionately.

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 the second quarter of 2016.
Lease operating. Our lease operating expenses increased by $3.9$6.4 million to $16.0$22.1 million, or an increase of 32%41%, for the three months ended June 30, 2017,March 31, 2018, as compared to $12.2$15.8 million for the three months ended June 30, 2016.March 31, 2017. Our lease operating expenses on a unit-of-production basis remained consistent at $4.77increased 2% to $5.44 per BOE for the three months ended June 30, 2017,March 31, 2018, as compared to $4.78$5.31 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.March 31, 2017. The increase in lease operating expenses on an absolute basis for the three months ended June 30, 2017,March 31, 2018, as compared to the three months ended June 30, 2016,March 31, 2017, was primarily attributable to an increase in costs of services and equipment related to the increased number of wells at June 30, 2017,March 31, 2018, as compared to June 30, 2016,March 31, 2017, as a result of our increased delineation and development drilling activities in the Delaware Basin.
Plant and other midstream services operating. Our plant and other midstream services operating expenses increased by $1.9 million to $2.9$4.2 million, or an increase of 177%80%, for the three months ended June 30, 2017,March 31, 2018, as compared to $1.1$2.3 million for the three months ended June 30, 2016.March 31, 2017. This increase was partially attributable to the(i) increased expenses associated with our expanded

commercial salt water disposal operations ofto $2.2 million for the three months ended March 31, 2018, as compared to $1.5 million for the three months ended June 30,March 31, 2017, as compared to $0.7 million for the three months ended June 30, 2016, as a result of additional salt water disposal wells operating in the second quarter of 2017. Most of the remaining increase was attributable toand (ii) increased expenses of $0.8 million associated with the Black River Processing Plant which began operating in August 2016.to $1.7 million for the three months ended March 31, 2018, as compared to $0.8 million for the three months ended March 31, 2017.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses increased by $10.0$21.4 million to $41.3$55.4 million, or an increase of 32%63%, for the three months ended June 30, 2017,March 31, 2018, as compared to $31.2$34.0 million for the three months ended June 30, 2016.March 31, 2017. On a unit-of-production basis, our depletion, depreciation and amortization expenses increased slightly to $12.28$13.59 per BOE for the three months ended June 30, 2017,March 31, 2018, as compared to $12.25$11.45 per BOE for the three months ended June 30, 2016.March 31, 2017. 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, and (ii) the 32%37% increase in total oil and natural gasequivalent production to 3.44.1 million BOE for the three months ended June 30, 2017,March 31, 2018, as compared to 2.63.0 million BOE for the three months ended June 30, 2016.March 31, 2017. The impact of the increase in well costs and oil and natural gas production on depletion, depreciation and amortization was mostlypartially offset by higher total proved oil and natural gas reserves of 134.4 million BOE, or an increase of 41%, at June 30, 2017,March 31, 2018, as compared to total proved reserves of 95.5 million BOE at June 30, 2016.March 31, 2017. The increase in total proved oil and natural gas reserves was primarily attributable to the continuedour ongoing delineation and development of our acreagedrilling activities in the Delaware Basin. In addition, depreciation expenses attributable to our midstream segment were approximately $1.3$1.5 million for the three months ended June 30, 2017,March 31, 2018, as compared to $0.5$1.2 million for the three months ended June 30, 2016.
Full-cost ceiling impairment. At June 30, 2017, we recorded no impairment charge to the net capitalized costs of our oil and natural gas properties. We recorded an impairment charge of $78.2 million to the net capitalized costs of our oil and natural gas properties for the three months ended June 30, 2016.March 31, 2017.
General and administrative. Our general and administrative expenses increased $4.0$1.6 million to $17.2$17.9 million, or an increase of 30%10%, for the three months ended June 30, 2017,March 31, 2018, as compared to $13.2$16.3 million for the three months ended June 30, 2016.March 31, 2017. The increase 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 alsoprimarily 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 $5.11 per BOE for the three months ended June 30, 2017, as compared to $5.18 per BOE for the three months ended June 30, 2016.
Interest expense. For the three months ended June 30, 2017, we incurred total interest expense of approximately $11.1 million. We capitalized approximately $1.9 million of our interest expense on certain qualifying projects for the three months ended June 30, 2017 and expensed the 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 to operations. The increase in total interest expense of $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 debt outstanding. At June 30, 2017, we had no borrowings outstanding and $0.8 million in letters of credit outstanding under our revolving credit agreement (the “Credit Agreement”) 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 senior notes.
Total income tax benefit. Our deferred tax assets exceeded our deferred tax liabilities at June 30, 2017 due to the deferred tax amounts generated by the full-cost ceiling impairment charges recorded in prior periods. As a result, we established a valuation allowance against the deferred tax assets beginning in the third quarter of 2015. We retained a full valuation allowance at June 30, 2017 due to uncertainties regarding the future realization of our deferred tax assets.
Six Months Ended June 30, 2017 as Compared to Six Months Ended June 30, 2016
Production taxes, transportation and processing. Our production taxes, transportation and processing expenses increased by approximately $6.2 million to $24.7 million, or 34%, for the six months ended June 30, 2017, as compared to $18.5 million for the six months ended June 30, 2016. On a unit-of-production basis, our production taxes, transportation and processing expenses 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. The increase in production taxes, transportation and processing expenses was primarily attributable to the $8.0 million increase in our production taxes to $14.1 million for the six months ended June 30, 2017, 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 processing expenses. Transportation and processing expenses decreased to $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. This decrease of $1.8 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 36% 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, the expenses for the six months ended June 30, 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 lease operating expenses increased by $5.1 million to $31.8 million, or 19%, for the six months ended June 30, 2017, as compared to $26.7 million for the six months ended June 30, 2016. Our lease operating expenses unit-of-production basis decreased 11% to $5.02 per BOE for the six months ended June 30, 2017, as compared to $5.66 per BOE for the six months ended June 30, 2016. The decrease achieved in lease operating expenses on a unit-of-production basis was 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 six months ended June 30, 2016. This decrease was partially offset by increased workover expenses in 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 increased by $15.1 million to $75.3 million, or 25%, for the six months ended June 30, 2017, as compared to $60.2 million for the six months ended June 30, 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, and (ii) the 34% increase in oil and natural gas production to 6.3 million BOE for the six months ended June 30, 2017, as compared to 4.7 million BOE for the six months ended June 30, 2016. The decrease in our depletion, depreciation and amortization expenses on a unit-of-production basis was attributable to (i) the impairment charges recorded in 2016 and (ii) higher total 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 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 $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, 2017, we recorded no impairment charge to the net capitalized costs of our oil and natural gas properties. 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.
General and administrative. Our general and administrative expenses increased $7.2 million to $33.5 million, an increase of 27%, for the six months ended June 30, 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$4.2 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$1.7 million due to our increased delineation and development activities in the Delaware Basin for the sixthree months ended June 30, 2017,March 31, 2018, as compared to the sixthree months ended June 30, 2016. OurMarch 31, 2017. As a result of the 37% increase in oil and natural gas production for the three months ended March 31, 2018, as compared to the three months ended March 31, 2017, our general and administrative expenses decreased 5%20% on a unit-of-production basis to $5.29$4.40 per BOE for the sixthree months ended June 30, 2017,March 31, 2018, as compared to $5.58$5.50 per BOE for the sixthree months ended June 30, 2016, primarily due to our increased total oil equivalent production.March 31, 2017.
Interest expense.For the sixthree months ended June 30, 2017,March 31, 2018, we incurred total interest expense of approximately $20.8$10.4 million. We capitalized approximately $3.2$1.9 million of our interest expense on certain qualifying projects for the sixthree months ended June 30, 2017March 31, 2018 and expensed the remaining $17.7$8.5 million to operations. For the sixthree months ended June 30, 2016,March 31, 2017, we incurred total interest expense of approximately $15.6$9.7 million. We capitalized $2.2$1.2 million of our interest expense on certain qualifying projects for the sixthree months ended June 30, 2016March 31, 2017 and expensed the remaining $13.4$8.5 million to operations. The increase in total interest expense of $5.3 million for the six months ended June 30, 2017, as compared to the six months ended June 30, 2016, was attributable to an increase in the average debt outstanding. At June 30, 2017, we had no borrowings outstanding and $0.8 million in letters of credit outstanding under our Credit Agreement 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 senior notes.

Liquidity and Capital Resources
Our primary use of capital has been, and we expect will continue to be during the remainder of 20172018 and for the foreseeable future, for the acquisition, exploration and development of oil and natural gas properties and for midstream investments. Excluding any possible significant acquisitions, we expect to fund our capital expenditure requirements through the remainder of 2017 with2018 through a combination of cash on hand, (including proceeds we received in connection with the formation of the Joint Venture), operating cash flows and borrowings under our Credit Agreementthird amended and restated revolving credit agreement, as amended (the “Credit Agreement”) (assuming availability under our borrowing base). We continually evaluate other capital sources, including borrowings under additional credit arrangements, the sale or joint venture of midstream assets or oil and natural gas producing assets or acreage, particularly in our non-core asset areas, as well as potential issuances of equity, debt or convertible securities, none of which may be 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,At March 31, 2018, we had cash totaling approximately $27.0 million and restricted cash totaling approximately $25.8 million, most of which is associated with San Mateo. By contractual agreement, the cash in the accounts held by our less-than-wholly-owned subsidiaries is not to be commingled with other of our cash and is to be used only to fund the capital expenditures and operations of these less-than-wholly-owned subsidiaries.
During the first quarter of 2018, the lenders under our Credit Agreement completed their review of the Company’s proved oil and natural gas reserves at December 31, 2017, and as a result, on March 5, 2018, the borrowing base was increased to $725.0 million and the maximum facility amount remained at $500.0 million. This March 2018 redetermination constituted the regularly scheduled May 1 redetermination. The Company elected to keep the lenders’ borrowing commitment at $400.0 million. Borrowings under the Credit Agreement are limited to the lowest of the borrowing base, the maximum facility amount

and the elected commitment. The Credit Agreement matures on October 16, 2020. At March 31, 2018, we announcedhad no outstanding borrowings under our Credit Agreement.
In April 2018, we accessed the formationline of San Mateo, a strategic joint venture with Five Pointcredit under our Credit Agreement to operatefund certain of our acreage and expandmineral acquisitions, as well as for our Delaware Basinongoing exploration and development and midstream assets. We received $171.5activities and for general corporate purposes. At May 2, 2018, we had $45.0 million in connection with the formation of the Joint Ventureborrowings outstanding under our Credit Agreement and may earn up to an additional $73.5approximately $3.0 million in performance incentives overoutstanding letters of credit issued pursuant to 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.Credit Agreement.
We expect that development of our Delaware Basin assets will be the primary focus of our operations and capital expenditures for the remainder of 2017.2018. We operated fiveplan to operate six contracted drilling rigs in the Delaware Basin and one contracted drilling rigthroughout the remainder of 2018. One of the six rigs is also expected to drill at least two additional salt water disposal wells in the Eagle FordRustler Breaks asset area for San Mateo during the second quarter of 2017.2018. Our 20172018 estimated capital expenditure budget consists of $400$530 to $420$570 million for drilling, completions, facilities and infrastructure and $56$70 to $64$90 million for midstream capital expenditures, which represents our 51% share of anSan Mateo’s 2018 estimated 2017 capital expenditure budgetexpenditures. During the first quarter of $110 to $1252018, we incurred capital expenditures of approximately $170.5 million for drilling, completions, facilities and infrastructure and approximately $23.3 million for midstream activities, which was 51% of San Mateo. We

have allocated substantiallyMateo’s capital expenditures of $45.7 million. Substantially all of our 2018 estimated 2017 capital expenditures will be allocated 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, ourOur 2018 Delaware Basin drilling program will continue to focus on the continued development of the Wolf and Rustler Breaks asset areas and the further delineation and development of the Antelope Ridge, Jackson Trust, Ranger/Arrowhead Antelope Ridge and Twin Lakes asset areas, although we may also continueanticipate continuing to delineate previously untested zonesintervals in the Wolf and Rustler Breaks asset areas.areas during 2018 as well. Depending on commodity prices, costs, opportunities in new asset areas like Antelope Ridge, liquidity and other factors, we may consider adding a seventh rig towards the end of 2018.
During the second quarter of 2017 andFrom January 1, 2018 through August 2, 2017,April 30, 2018, we acquired approximately 8,3003,500 net leasehold and mineral 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.
for a total acquisition cost of approximately $30 million. We planintend to continue our leasingacquiring acreage and acquisitions effortsmineral interests, principally in the Delaware Basin, during the remainder of 2017 and may also continue acquiring acreage in the Eagle Ford and Haynesville shales.2018. These expenditures are opportunity-specific and per-acre prices can vary significantly based on the opportunity.prospect. As a result, it is difficult to estimate these 20172018 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, 2017, we had cash totaling approximately $131.5 million and restricted cash totaling approximately $15.0 million, most of which is associated with San Mateo. By contractual agreement, the cash 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. Additionally, at June 30, 2017, we had no outstanding borrowings under our Credit Agreement, which has a borrowing base of $450.0 million and an elected commitment of $400.0 million.2018.
Our 20172018 capital expenditures may be adjusted as business conditions warrant and the amount, timing and allocation of such 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 partnerjoint venture partners to meet itstheir capital obligations, other opportunities that may become available to us and our ability to obtain capital. When oil or natural gas prices decline, 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 20172018 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 forecastinghave forecasted 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 20172018 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 liquidsliquid (“NGL”) prices and to partially offset reductions in our cash flows from operations resulting from declines in commodity prices. As of August 2, 2017, we had approximately 65% of our anticipated oil production and approximately 70% of our anticipated natural gas production hedged for the remainder of 2017. See Note 87 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our open derivative financial instruments at June 30, 2017.March 31, 2018.

Cash Flows Provided by Operating Activities
Net cash provided by operating activities increased $71.6$74.8 million to $121.2$136.1 million for the sixthree months ended June 30, 2017March 31, 2018 from $49.6$61.3 million for the sixthree months ended June 30, 2016.March 31, 2017. Excluding changes in operating assets and liabilities, net cash provided by operating activities increased to $130.9$114.8 million for the sixthree months ended June 30, 2017March 31, 2018 from $43.5$63.8 million for the sixthree months ended June 30, 2016.March 31, 2017. This increase was primarily attributable to higher oil and natural gas production and higher commodity prices and was partially offset by the decrease in our realized gains on derivatives and an increase in certain expenses.oil prices. Changes in our operating assets and liabilities between the two periods resulted in a net decreaseincrease of approximately $15.8$23.8 million in net cash provided by operating activities for the sixthree months ended June 30, 2017,March 31, 2018, as compared to the sixthree months ended June 30, 2016.March 31, 2017.
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 liquidsNGL 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 increaseddecreased by $217.4$4.2 million to $383.5$220.8 million for the sixthree months ended June 30, 2017March 31, 2018 from $166.0$225.0 million for the sixthree months ended June 30, 2016.March 31, 2017. This increasedecrease in net cash used in investing activities is primarily due to an increasea decrease of $166.5$21.0 million in oil and natural gas properties capital expenditures for the sixthree months ended June 30, 2017,March 31, 2018, as compared to the sixthree months ended June 30, 2016.March 31, 2017. Cash used for oil and natural gas properties capital expenditures for the sixthree months ended June 30, 2017March 31, 2018 was primarily attributable to the acquisition of additional leasehold and mineral interests and to our operated drilling and completion activities in the Delaware Basin. A small portion of our capital expenditures for the six months ended June 30, 2017This decrease was directed to our participation in non-operated wells and our operated drilling and completion activities in the Eagle Ford shale. Additionally, there waspartially offset by 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 midstream and other property and equipment of approximately $5.8 million.$16.5 million primarily related to capital expenditures for San Mateo.
Cash Flows Provided by Financing Activities
Net cash provided by financing activities increaseddecreased by $40.2$138.9 million to $180.8$34.9 million for the sixthree months ended June 30, 2017March 31, 2018 from $140.6$173.8 million for the sixthree months ended June 30, 2016. The increase in net cash provided by financing activities forMarch 31, 2017. During the sixthree months ended June 30, 2017 was primarilyMarch 31, 2018, we received net proceeds of $14.7 million attributable to (i) the increase of $171.5 millionperformance incentives related to contributions from the formation of the Joint Venture and (ii) theSan Mateo as well as net increasecash of $12.7$24.5 million relatedattributable 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 outflowssubsidiaries. During the three months ended March 31, 2017, we received net proceeds of $2.7$171.5 million related to the purchaseformation 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 ($141.6 million including cost to issue equity).

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 a 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 income (loss) and net cash provided by operating activities, respectively.

Off-Balance Sheet Arrangements
From time-to-time, we enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations. As of June 30, 2017,March 31, 2018, the material off-balance sheet arrangements and transactions that we have entered into include (i) operating lease agreements, (ii) non-operated drilling commitments, (iii) termination obligations under drilling rig contracts, (iv) firm transportation, gathering, processing disposal and fractionationdisposal commitments and (v) contractual obligations for which the ultimate settlement amounts are not fixed and determinable, such as derivative contracts that are sensitive to future changes in commodity prices or interest rates, gathering, treating, fractionationtransportation and transportationdisposal commitments on uncertain volumes of future throughput, open delivery commitments and indemnification obligations following certain divestitures. Other than the off-balance sheet arrangements described above, the Company has no transactions, arrangements or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect the Company’s liquidity or availability of or requirements for capital resources.

At June 30, 2017March 31, 2018, we had no borrowings outstanding under our Credit Agreement and approximately $0.82.1 million in outstanding letters of credit issued pursuant to the Credit Agreement. The Credit Agreement matures in October 2020.
(2)The amounts included in the table above represent principal maturities only. Interest expense on our 6.875% senior notes due 2023 that are outstanding as of March 31, 2018 is expected to be approximately $39.5 million each year until maturity.
(3)At June 30, 2017,March 31, 2018, we had outstanding commitments to participate in the drilling and completion of various non-operated wells. Our working interests in these wells are typically small, and certain of these wells were in progress at June 30, 2017.March 31, 2018. If all of these wells are drilled and completed, we will have minimum outstanding aggregate commitments for our participation in these wells of approximately $19.7$30.1 million at June 30, 2017,March 31, 2018, which we expect to incur within the next year.
(4)We do not own or operate our own drilling rigs, but instead enter into contracts with third parties for such drilling rigs. See Note 109 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for more information regarding ourthese contractual commitments.
(5)Effective September 1, 2012, we entered into a firm five-year natural gas processing and transportation agreement for a significant portion of our operated natural gas production in South Texas. Effective October 1,In late 2015, we entered into a 15-year fixed-fee natural gas gathering and processing agreement for a significant portion of our operated natural gas production in Loving County, Texas. In late 2017, we entered into an 18-year fixed-fee natural gas transportation agreement where we committed to deliver a portion of the residue natural gas production at the tailgate of the Black River Processing Plant to transport through the counterparty’s pipeline in Eddy County, New Mexico. In late 2017, we also entered into a fixed-fee NGL transportation and fractionation agreement whereby we committed to deliver our NGL production at the tailgate of the Black River Processing Plant. We have committed to deliver a minimum amount of NGLs to the counterparty upon construction and completion of a pipeline expansion and a fractionation facility by the counterparty, which is currently expected to be completed late in 2019. We have no rights to compel the counterparty to construct this pipeline extension or fractionation facility. If the counterparty does not construct the pipeline extension and fractionation facility, then we do not have any minimum volume commitments under the agreement. If the counterparty constructs the pipeline extension and fractionation facility on or prior to February 28, 2021, then we will have a commitment to deliver a minimum amount of NGLs for seven years following the completion of the pipeline extension and fractionation facility. If we do not meet our NGL volume commitment in any quarter during the seven-year commitment period, we will be required to pay a deficiency fee per gallon of NGL deficiency. The amounts in the table assume that the seven-year period containing minimum NGL volume commitments begins in late 2019. See Note 9 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for more information regarding these contractual commitments.

General Outlook and Trends
For the three months ended June 30, 2017,March 31, 2018, oil prices averaged $48.15$62.86 per Bbl, ranging from a high of $53.40$66.14 per Bbl in mid-Aprillate January to a low of $42.53$59.19 per Bbl in late June,mid-February, based upon the NYMEX West Texas Intermediate oil futures contract price for the earliest delivery date. We realized ana weighted average oil price of $46.01$62.20 per Bbl ($46.3460.40 per Bbl including realized gainslosses from oil derivatives) for our oil production for the three months ended June 30, 2017,March 31, 2018, as compared to $42.84$50.72 per Bbl ($43.2949.73 per Bbl including realized gainslosses from oil derivatives) for the three months ended June 30, 2016.March 31, 2017. At AugustMay 2, 2017,2018, the NYMEX West Texas Intermediate oil futures contract for the earliest delivery date had increased from the weighted average price for the secondfirst quarter of 2017,2018, settling at $49.59$67.93 per Bbl, which was also ana significant increase as compared to $39.51$47.66 per Bbl at AugustMay 2, 2016.2017.
For the three months ended June 30, 2017,March 31, 2018, natural gas prices averaged $3.14$2.85 per MMBtu, ranging from a high of approximately $3.42$3.63 per MMBtu in mid-Maylate January to a low of approximately $2.89$2.55 per MMBtu in late June,mid-February, 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$3.33 per Mcf ($3.39 per Mcf including(with essentially no realized gains or losses from natural gas derivatives) for our natural gas production (including revenues attributable to natural gas liquids)NGLs) for the three months ended June 30, 2017,March 31, 2018, as compared to $2.10$3.94 per Mcf ($2.343.86 per Mcf, including realized gainslosses from natural gas derivatives) for the three months ended June 30, 2016.March 31, 2017. At AugustMay 2, 2017,2018, the NYMEX Henry Hub natural gas futures contract for the earliest delivery date had decreased from the weighted average price for the secondfirst quarter of 2017,2018, settling at $2.81$2.76 per MMBtu, which was also a small increasedecrease as compared to $2.73$3.20 per MMBtu at AugustMay 2, 2016.2017.
The prices we receive for oil, natural gas and natural gas liquidsNGLs 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 liquidsNGLs 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 liquidsNGLs have been volatile and these markets will likely continue to be volatile in the future. Declines in oil, natural gas or natural gas liquidsNGL prices not only reduce our revenues, but could also reduce the amount of oil, natural gas and natural gas liquidsNGLs we can produce economically. We are uncertain 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 liquidsNGL 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 liquidsNGL 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.
In addition, the prices we receive for our oil and natural gas production, in particular, often reflect a discount to the relevant benchmark prices, such as the NYMEX West Texas Intermediate oil price or the NYMEX Henry Hub natural gas price. The difference between these benchmark prices and the price we receive is called a differential. At March 31, 2018, most of our oil production from the Delaware Basin was sold based on prices established in Midland, Texas and most of our natural gas production from the Delaware Basin was sold based on prices established at the Waha Hub in far West Texas. During the first quarter of 2018, the price differentials for oil sold in Midland and natural gas sold at the Waha Hub compared to the benchmark prices for oil and natural gas, respectively, began to widen significantly. Although these widening differentials did not significantly impact our oil and natural gas revenues in the first quarter of 2018, these widening differentials are expected to negatively impact our oil and natural gas revenues beginning in the second quarter of 2018.
In early May 2018, these price differentials were approximately ($10.00) per barrel for oil and ($1.50) per MMBtu for natural gas. We anticipate that these widening price differentials could persist for 12 to 18 months or longer until additional oil and natural gas pipeline capacity from West Texas to the Texas Gulf Coast and other end markets is completed; however, we can provide no assurances as to how long these widening differentials may persist and, in fact, these price differentials could widen further in future periods. At May 2, 2018, we had approximately 55% of our anticipated Delaware Basin oil production for the remainder of 2018 hedged at a weighted average basis differential swap price of ($1.02) per barrel to help mitigate our exposure to these widening oil basis differentials. See Note 7 to the interim unaudited condensed consolidated financial statements in this Quarterly Report for a summary of these oil basis swaps. At May 2, 2018, we had no hedges in place to mitigate our exposure to basis differentials for our natural gas production.

Coinciding with the recent improvements in oil and natural gas prices since the latter part of 2016, we have begun to experienceexperienced price increases from certain of our service providers for some of the products and services we use in our drilling, completion and production operations. If oil 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 liquidsNGL price declines, however, drilling certain oil or natural gas wells may not be economical,economic, 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
Except as set forth below, there have been no material changes to the sources and effects of our market risk since December 31, 2016,2017, which are disclosed in Part II, Item 7A of the Annual 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 liquidsNGLs 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 liquidsNGL prices. CostlessTraditional costless collars provide us with downside price protection through the purchase of a put option whichthat 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. Participating three-way costless collars also provide the Company with downside price protection through the purchase of a put option, but they also allow the Company to participate in price upside through the purchase of a call option; the purchase of both the put option and the call option are financed through the sale of a call option. Because the proceeds from the call option sale are used to offset the cost of the purchased put and call options, these arrangements are also initially “costless” to the Company. In the case of a costless collar, the put option and the call option or options have different fixed price components. In a swap contract, a floating price is exchanged for a fixed price over a specified period, providing downside price protection.
