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.Louisiana. Additionally, the Company conducts midstream operations, primarily through its midstream joint ventures, San Mateo Midstream, LLC (“San Mateo I”) and San Mateo Midstream II, LLC (“San Mateo II” and, together with San Mateo I, “San Mateo”), in support of the Company’s exploration, development and production operations and provides natural gas processing, oil transportation services, oil, natural gas and salt water gathering services and salt water disposal services to third 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 the 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, 20182019 filed with the SEC on March 1, 20192, 2020 (the “Annual Report”). 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”), Consolidation (Topic 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 normal, recurring adjustments that are necessary for a fair presentation of the Company’s interim unaudited condensed consolidated financial statements as of June 30, 2019.March 31, 2020. Amounts as of December 31, 20182019 are derived from the Company’s audited consolidated financial statements included in the Annual Report. Certain reclassifications have been made to the December 31, 2018 financial statement amounts in order to conform them to the June 30, 2019 presentations.
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 oil and natural gas revenues, accrued assets and liabilities, stock-based compensation, valuation of derivative instruments, deferred tax assets and liabilities and oil and natural gas reserves. The estimates of oil and natural gas reserves quantities and future net cash flows are the basis for the calculations of depletion and impairment of oil and natural gas properties, as well as estimates of asset retirement obligations and certain tax accruals. While the Company believes its estimates are reasonable, changes in facts and assumptions or the discovery of new information may result in revised estimates. Actual results could differ from these estimates.
Change in Accounting PrinciplesRevenues
Leases. DuringThe following table summarizes the first quarter ofCompany’s total revenues and revenues from contracts with customers on a disaggregated basis for the three months ended March 31, 2020 and 2019 the Company adopted Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) and the amendments provided for in ASU 2018-11, Leases (Topic 842),which require the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous U.S. GAAP using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that the Company chose to apply. These practical expedients relate to (i) the identification and classification of leases that commenced before the effective date, (ii) the treatment of initial direct costs for leases that commenced before the effective date, (iii) the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset and (iv) the ability to initially apply the new lease standard at the adoption date. During the first quarter of 2019, the Company also adopted ASU 2018-01, Leases (Topic 842), which is a land easement practical expedient, and, as a result, the Company began evaluating land easements that are entered into or modified after December 31, 2018. See Note 3 for additional disclosures related to leases.(in thousands).

The adoption of these ASUs resulted in the Company recording in the condensed consolidated balance sheet beginning January 1, 2019 certain of the Company’s compressor leases, drilling rig leases and office leases, which were previously considered operating leases and not reported on the Company’s condensed consolidated balance sheets. As such, upon adoption, the Company recorded (i) long-term right of use assets of $62.3 million, which are included in “Other assets” and “Other property and equipment,” and (ii) net right of use liabilities of $62.3 million, which are included in “Other current liabilities” and “Other long-term liabilities.” There was no cumulative-effect adjustment to the opening balance of accumulated deficit as a result of the adoption of these ASUs.
Stock Compensation. During the first quarter of 2019, the Company also adopted ASU 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting,which extends the scope of Topic 718 to include share-based payment transactions related to the acquisition of goods and services from nonemployees. Previously, the Company accounted for stock-based awards to special advisors and contractors under ASC 505-50 as liability instruments, and the fair value of the awards was recalculated each reporting period. Upon adoption, all such awards are now measured at fair value on the grant date and the resulting expense is recognized on a straight-line basis over the awards’ vesting periods. The transitional guidance requires entities to remeasure all unvested awards that are being accounted for under ASC 505-50 as liability instruments as of the beginning of the year in which this ASU is adopted. Adoption of this ASU did not have a material impact on the Company’s condensed 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, 2020 and 2019, and 2018, the cost center ceiling was higher than the capitalized costs of oil and natural gas properties, and, as a result, no0 impairment charge was necessary.
The Company capitalized approximately $8.4$8.2 million and $6.8$8.4 million of its general and administrative costs and approximately $2.6$1.4 million and $2.6$1.6 million of its interest expense for the three months ended June 30,March 31, 2020 and 2019, and 2018, respectively. The Company capitalized approximately $16.8 million and $14.1 million of its general and administrative costs and approximately $4.2 million and $4.5 million of its interest expense for the six months ended June 30, 2019 and 2018, respectively.

NOTE 3 — LEASES

The Company determines if an arrangement is a lease at inception of the contract. If an arrangement is a lease, the present value of the related lease payments is recorded as a liability and an equal amount is capitalized as a right of use asset on the Company’s interim unaudited condensed consolidated balance sheet. Right of use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising Additionally, 0.8 million restricted shares, which are participating securities, were excluded from the lease. The Company’s estimated incremental borrowing rate, determined at the lease commencement date using the Company’s average secured borrowing rate, is used to calculate present value. The weighted average estimated incremental borrowing rate usedcalculations above for the three months ended June 30,March 31, 2019, was 3.73%. For these purposes,as the lease term includes optionssecurity holders do not have the obligation to extendshare in the lease when it is reasonably certain that the Company will exercise such option. Leases with terms of 12 months or less at inception are not recorded on the interim unaudited condensed consolidated balance sheet unless there is a significant cost to terminate the lease, including the cost of removallosses of the leased asset. As the Company is the responsible party under these arrangements, the Company records the resulting assets and liabilities on a gross basis in its interim unaudited condensed consolidated balance sheets.
The following table presents supplemental interim unaudited condensed consolidated statement of operations information related to lease expenses, on a gross basis, for the three and six months ended June 30, 2019 (in thousands). Lease payments represent gross payments to vendors, which, for certain of our operating assets, are partially offset by amounts received from other working interest owners in our operated wells.

NOTE 65 — INCOME TAXES
The Company’s effective tax raterates for the three and six months ended June 30,March 31, 2020 and 2019 was 26%were 24% and 37%33%, respectively. The Company’s total income tax provision for the three and six months ended June 30,March 31, 2020 and 2019 differed from amounts computed by applying the U.S. federal statutory tax rates to pre-tax income due primarily to the impact of permanent differences between book and tax income at June 30, 2019.
Due to a variety of factors, including the Company’s significant net incomeand state taxes, primarily in 2017 and 2018, the Company’s federal valuation allowance and a portion of the Company’s state valuation allowance were reversed at December 31, 2018 as the deferred tax assets were determined to be more likely than not to be utilized. As a portion of the Company’s state net operating loss carryforwards are not expected to be utilized before expiration, a valuation allowance will continue to be recognized until the state deferred tax assets are more likely than not to be utilized.
The Company’s deferred tax assets exceeded its deferred tax liabilities at June 30, 2018 due to the deferred tax assets generated by full-cost ceiling impairment charges in prior periods. The Company established a valuation allowance against most of the deferred tax assets beginning in the third quarter of 2015 and retained a full valuation allowance at June 30, 2018 due to uncertainties regarding the future realization of its deferred tax assets.New Mexico.

In April 2020, the Company restructured a portion of its oil derivative contracts, increasing its oil volumes hedged during the period from April through December 2020. As part of this restructuring, the Company repurchased the call options on certain existing open costless collars and kept the remaining put options, which represent options to sell at a specific exercise price, exchanged certain existing open costless collars and added swaps.
As a result of this restructuring process, the Company’s open oil derivative contracts for the period from April through December 2020 have changed. The restructuring transactions were executed with the same counterparties and were costless to the Company. As a result, the execution of the restructuring transactions is not expected to have a material impact on the consolidated financial statements of the Company. No changes were made to the Company’s open oil basis swaps from those positions noted above. In April 2020, the Company also entered into oil swaps for 2021 and natural gas collars for late 2020 and early 2021.

NOTE 98 — 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 that 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, 2019March 31, 2020 and December 31, 20182019 (in thousands).

At June 30,March 31, 2020 and December 31, 2019, the carrying value of borrowings under the Credit Agreement and the San Mateo Credit Facility approximated their fair value as both are subject to short-term floating interest rates that reflect market rates available to the Company at the time and are classified at Level 2 in the fair value hierarchy.
At June 30, 2019 and December 31, 2018, the fair value of the Notes was $1.07 billion and $0.97 billion, respectively, based on quoted market prices, which represent Level 1 inputs in the fair value hierarchy.

Operations Update
During the secondfirst quarter of 2019,2020, the oil and natural gas industry witnessed an abrupt and significant decline in oil prices from $63 per Bbl in early January to just above $20 per Bbl in late March. This sudden decline in oil prices was attributable to two primary factors: (1) the precipitous decline in global oil demand resulting from the worldwide spread of the novel coronavirus (“COVID-19”) and (2) a sudden, unexpected increase in global oil supply resulting from actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts by members of the Organization of Petroleum Exporting Countries and Russia (“OPEC+”) to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria. Primarily as a result of these unexpected events and the resulting declines in oil prices, Matador has significantly modified its 2020 operational plan.
We began 2020 operating six drilling rigs in the Delaware Basin, as we continued ourto 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 2019 operatinghad originally planned to operate these six drilling rigs in the Delaware Basin and continued to do so at June 30, 2019. Duringthroughout 2020. As a result of the secondevents noted above, however, we released one operated drilling rig from our Wolf asset area in Loving County, Texas late in the first quarter of 2019, these six2020, and we released a second operated drilling rigs were deployed across our Delaware Basin asset areas, but with an increased focus on the Antelope Ridge asset area. We expect to operate six rigs in the Delaware Basin throughout the remainder of 2019, with four rigs operating between the Rustler Breaks and Antelope Ridge asset areas, one rig operating in the Wolf and Jackson Trust asset areas and one rig operating in the Arrowhead, Ranger and Twin Lakes asset areas, although this rig, in particular, is expected to operate primarily infrom the Stebbins area and surrounding leaseholds in the southern portion of the Arrowhead asset area (the “Greater Stebbins Area”) forin late April 2020. We anticipate releasing one additional drilling rig by the remainderend of 2019.
We also concluded completion operations on our nine-well program in South Texas during the second quarter of 2019, which included eight completions2020. Thereafter, we expect to operate three drilling rigs in the Eagle Ford formation and one test of the Austin Chalk formation. The final four wells in this nine-well program were completed and turned to sales in the second quarter of 2019. These wells included two Eagle Ford completions on the Haverlah leasehold in Atascosa County, which were turned to sales in April, and two additional Eagle Ford completions on the Lloyd Hurt leasehold, which were turned to sales in May 2019. The rig used to drill these nine wells was released in early February 2019, and we have no additional operated drilling activities planned in the Eagle Ford shale forDelaware Basin throughout the remainder of 2019.2020. Two of these rigs are anticipated to operate in our Stateline asset area in Eddy County, New Mexico, and the third rig is expected to operate primarily in the Rustler Breaks and Antelope Ridge asset areas.
We completed and turned to sales a total of 1936 gross (15.1(15.9 net) wells in the Delaware Basin during the secondfirst quarter of 2019,2020, including 1417 gross (13.1(15.6 net) operated horizontal wells twoand 19 gross (2.0 net) operated vertical wells and three gross (0.1(0.3 net) non-operated horizontal wells. During the secondfirst quarter of 2019,2020, we completed and turned to sales a total of 17 gross (10.5 net) wells in the Antelope Ridge asset area, including 11 gross (10.4 net) operated wells and six gross (0.1 net) non-operated wells. The 11 gross operated wells turned to sales in the Antelope Ridge asset area included two Avalon completions, one First Bone Spring completion, four Second Bone Spring completions, one Third Bone Spring completion, two Wolfcamp A completions and one Wolfcamp B completion. These wells also included the first six gross (6.0 net) “Rodney Robinson” wells completed in the western portion of the Antelope Ridge asset area. The 1,200 gross and net acre Rodney Robinson tract is one of the key tracts we acquired in the BLM New Mexico Oil and Gas Lease Sale in September 2018 (the “BLM Acquisition”). These six Rodney Robinson wells, all two-mile laterals, were also the first wells drilled and completed on the 8,400 gross and net acres we acquired in the BLM Acquisition.
In the Rustler Breaks asset area, we began producing oil and natural gas from a total of 1216 gross (8.5(2.8 net) wells, in the Antelope Ridge asset area, including ninethree gross (8.4(2.6 net) operated wells and three13 gross (0.1(0.2 net) non-operated wells. Of the ninethree gross operated wells completed and turned to sales in the Antelope RidgeRustler Breaks asset area, two were Wolfcamp A-XY completions, three were First Bone Spring completions, three were Third Bone SpringA completions and one was a vertical completion in the Wolfcamp formation. In the Rustler Breaks and Arrowhead asset areas, we did not complete or turn to sales any operated or non-operated wells during the second quarter of 2019.B completion. In the Wolf and Jackson Trust asset areas, we began producing oil and natural gas from twothree gross (1.8(2.6 net) operated wells during the secondfirst quarter of 2019, including one2020, all of which were Wolfcamp B completion and one Second Bone Spring completion. In addition, we began producing oil and natural gas from a total of four gross (3.9 net) operated wells in the Ranger asset area during the second quarter of 2019, including one First Bone Spring completion, two Second Bone Spring completions and one Third Bone Spring completion. Finally, in the Twin Lakes asset area, we began producing oil and natural gas from one gross (1.0 net) well, a vertical completion in the Morrow formation, during the second quarter of 2019.A completions.
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 12 months. Our total Delaware Basin production for the secondfirst quarter of 20192020 was 51,75860,300 BOE per day, consisting of 32,84038,500 Bbl of oil per day and 113.5130.9 MMcf of natural gas per day, an 11%a 15% increase from production of 46,48952,600 BOE per day, consisting of 27,38132,000 Bbl of oil per day and 114.6123.9 MMcf of natural gas per day, in the secondfirst quarter of 2018.2019. The Delaware Basin contributed approximately 89%95% of our daily oil production and approximately 77%71% of our daily natural gas production in the secondfirst quarter of 2019,2020, as compared to approximately 92%93% of our daily oil production and approximately 82%81% of our daily natural gas production in the secondfirst quarter of 2018.2019.
WeDuring the first quarter of 2020, we did not conduct any operated drilling and completion activities on our leasehold properties in the Eagle Ford shale play in South Texas or in the Haynesville shale and Cotton Valley plays in Northwest Louisiana and East Texas in the second quarter of 2019, although weLouisiana. We did participate in eightthe drilling and completion of three gross (0.3(less than 0.1 net) non-operated Haynesville shale wells that were completed and turned to sales.sales in the first quarter of 2020.

Capital Resources UpdateBorrowing Base Increased
In April 2019,February 2020, the lenders underparty to our reserves-based revolving credit agreementfacility (the “Credit Agreement”), led by Royal Bank of Canada, completed their review of ourthe Company’s proved oil and natural gas reserves at December 31, 2018,2019, and, as a result, the borrowing base was increasedaffirmed at $900.0 million. The Company elected to $900.0 million withincrease the elected borrowing commitment remaining atfrom $500.0 million.million to $700.0 million, and the maximum facility amount remained $1.5 billion. We also added two new banks to our lending group as part of this redetermination process. This April 2019February 2020 redetermination constituted the regularly scheduled May 1 redetermination. Borrowings under the Credit Agreement are limited to the lowest of the borrowing base, the maximum facility amount and the elected borrowing commitment.
In June 2019, the lender commitments under San Mateo I’s revolving credit facility (the “San Mateo Credit Facility”), led by The Bank of Nova Scotia, were increased to $325.0 million, using the accordion feature. The San Mateo Credit Facility is guaranteed by San Mateo I’s subsidiaries, secured by substantially all of San Mateo I’s assets, including real property, and is non-recourse with respect to Matador and its wholly-owned subsidiaries, as well as San Mateo II.
20192020 Capital Expenditure Budget
On July 31, 2019,April 29, 2020, we increaseddecreased the range of our anticipated 2019 midstream capital expenditures from $55 to $75 million to $70 to $90 million, primarily for capital expenditures necessary to accommodate new customers and increased commitments from existing customers. The anticipated 2019 midstream capital expenditures reflect our proportionate share of San Mateo’s estimated 2019 capital expenditures and also account for portions of the $50 million capital carry that Five Point Energy LLC (“Five Point”) agreed to provide to us in conjunction with the formation of San Mateo II.
At July 31, 2019, our 2019 estimatedfull-year 2020 capital expenditures for drilling, completing and equipping wells from $690.0 to $750.0 million to $440.0 to $500.0 million, as we plan to reduce our operated drilling program from six rigs to three rigs by June 30, 2020, as noted above. At April 29, 2020, the range of our estimated 2020 midstream capital expenditures remained $640$85.0 to $680 million, despite an increase of four gross (6.8 net) additional operated wells expected to be completed and turned to sales in 2019, as compared to our original estimates.$105.0 million. See “— Liquidity and Capital Resources — 20192020 Capital Expenditure Budget” for more information regardinginformation.
Restructuring of Derivative Financial Instruments
During April 2020, we restructured a portion of our 2019 capital expenditure budget.then-existing 2020 West Texas Intermediate (“WTI”) oil derivative financial instruments, providing additional revenue protection should oil prices remain at currently depressed levels for the remainder of 2020 or should further market disruptions occur. As a result of these modifications, we almost doubled our oil volumes hedged for the period from April through December 2020. At April 29, 2020, we had approximately 10.3 million Bbl of oil hedged for the period from April through December 2020. These restructured derivative financial instruments include approximately 7.6 million Bbl of fixed-price oil swaps at a weighted average price of approximately $35 per Bbl and 2.3 million Bbl of oil collars with a weighted average floor price of approximately $48 per Bbl and a weighted average ceiling price of approximately $66 per Bbl. We also have approximately 0.4 million Bbl in oil put options, which represent options to sell at a specified exercise price, at a weighted average price of approximately $48 per Bbl for the period from April through June 2020.
In addition, during April 2020, we added approximately 5.5 million Bbl of oil swaps at a weighted average price of approximately $35 per Bbl for 2021. We also added natural gas collars for November and December 2020 for approximately 3.2 million MMBtu and for the first quarter of 2021 for approximately 4.8 million MMBtu, each with a weighted average floor price of approximately $2.52 per MMBtu and a weighted average ceiling price of approximately $3.71 per MMBtu.

Three Months Ended June 30, 2019March 31, 2020 as Compared to Three Months Ended June 30, 2018March 31, 2019
Oil and natural gas revenues. Our oil and natural gas revenues increased $2.0$4.6 million, or 1%2%, to $211.1$197.9 million for the three months ended June 30, 2019,March 31, 2020, as compared to $209.0$193.3 million for the three months ended June 30, 2018.March 31, 2019. Our oil revenues increased $22.8$15.4 million, or 14%10%, to $189.1169.6 million for the three months ended June 30, 2019March 31, 2020, as compared to $166.3154.2 million for the three months ended June 30, 2018March 31, 2019. The increase in oil revenues resulted from the 24%19% increase in our oil production to 3.33.7 million Bbl of oil for the three months ended June 30, 2019,March 31, 2020, as compared to 2.73.1 million Bbl of oil for the three months ended June 30, 2018.March 31, 2019. The increase in oil production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin. This increase was partially offset by a lower weighted average oil price realized for the three months ended June 30, 2019March 31, 2020 of $56.51$45.87 per Bbl, a decrease of 8% as compared to $61.44$49.64 per Bbl realized for the three months ended June 30, 2018.March 31, 2019. Our natural gas revenues decreased by $20.8$10.7 million, or 49%27%, to $22.0$28.3 million for the three months ended June 30, 2019,March 31, 2020, as compared to $42.7$39.1 million for the three months ended June 30, 2018.March 31, 2019. The decrease in natural gas revenues resulted from a 51%40% decrease in realized natural gas prices to $1.64$1.70 per Mcf for the three months ended June 30, 2019,March 31, 2020, as compared to $3.38$2.85 per Mcf realized for the three months ended June 30, 2018.March 31, 2019. This decrease was partially offset by the 6%22% increase in our natural gas production to 13.416.7 Bcf for the three months ended June 30, 2019,March 31, 2020, as compared to 12.713.7 Bcf for the three months ended June 30, 2018.March 31, 2019. The increase in natural gas production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.Basin as well as from significant volumes of natural gas production associated with two non-operated Haynesville shale wells completed and placed on production during the third quarter of 2019.

Third-party midstream services revenues. Our third-party midstream services revenues increased $11.0$4.0 million, or more than four-fold,34%, to $14.4$15.8 million for the three months ended June 30, 2019,March 31, 2020, as compared to $3.4$11.8 million for the three months ended June 30, 2018.March 31, 2019. 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 (i) an increase in our third-party salt water gathering and disposal revenues to approximately $6.3 million for the three months ended June 30, 2019, as compared to approximately $1.9 million for the three months ended June 30, 2018, and (ii) an increase in our third-party natural gas gathering, transportation and processing revenues to approximately $6.5$7.1 million for the three months ended June 30, 2019,March 31, 2020, as compared to $1.5$4.5 million for the three months ended June 30, 2018.March 31, 2019, and (ii) an increase in our third-party salt water gathering and disposal revenues to approximately $6.7 million for the three months ended March 31, 2020, as compared to approximately $5.7 million for the three months ended March 31, 2019.
Sales of purchased natural gas. Our sales of purchased natural gas were $9.0decreased $0.7 million, or 6%, to $10.5 million for the three months ended June 30, 2019. We had no sales of purchased natural gasMarch 31, 2020, as compared to $11.2 million for the three months ended June 30, 2018.March 31, 2019. The decrease was the result of a decrease in both the volume sold and the weighted average natural gas price realized for the three months ended March 31, 2020. Sales of purchased natural gas primarily reflect those natural gas purchase transactions that we periodically enter into with third parties whereby we purchase natural gas, process the third party’s natural gas at theSan Mateo’s Black River cryogenic natural gas processing plant in Eddy County, New Mexico (the “Black River Processing Plant”) and then purchase, and subsequently sell the residue gas and natural gas liquids (“NGL”) to other purchasers. These revenues, and the expenses related to these transactions included in “Purchased natural gas,” are presented on a gross basis in our interim unaudited condensed consolidated statement of operations.
Realized gain (loss) on derivatives. Our realized net gain on derivatives was $1.2$10.9 million for the three months ended June 30, 2019,March 31, 2020, as compared to a realized net lossgain of $2.5$3.3 million for the three months ended June 30, 2018.March 31, 2019. We realized a net gain of $1.2$11.5 million related to our oil costless collar contracts for the three months ended June 30, 2019,March 31, 2020, resulting from oil prices that were below the floor prices of certain of our oil costless collar contracts. We realized a net loss of $0.6 million related to our oil basis swap contracts for the three months ended March 31, 2020, resulting from oil basis prices that were above the fixed prices of certain of our oil basis swap contracts. We realized an average gain on our oil derivatives contracts of approximately $0.35$2.94 per Bbl produced during the three months ended June 30, 2019,March 31, 2020, as compared to an average lossgain of approximately $0.92$1.08 per Bbl produced during the three months ended June 30, 2018.March 31, 2019. Our total oil volumes hedged for the three months ended June 30, 2019March 31, 2020 represented 68%54% of our total oil production, as compared to 51%44% of our total oil production for the three months ended June 30, 2018. Our total natural gas volumes hedged for the three months ended June 30, 2019 represented 13% of our total natural gas production, as compared to 33% of our total natural gas production for the three months ended June 30, 2018.March 31, 2019.
Unrealized gain (loss) on derivatives. Our unrealized net gain on derivatives was $6.2$136.4 million for the three months ended June 30, 2019,March 31, 2020, as compared to an unrealized net gainloss of $1.4$45.7 million for the three months ended June 30, 2018.March 31, 2019. During the three months ended June 30, 2019,March 31, 2020, the net fair value of our open oil and natural gas derivative contracts increased to a net asset of $10.3$132.6 million from a net assetliability of $4.1$3.9 million at MarchDecember 31, 2019, resulting in an unrealized gain on derivatives of $6.2$136.4 million for the three months ended June 30, 2019.March 31, 2020. During the three months ended June 30, 2018, the net fair value of our open oil and natural gas derivative contracts increased to a net liability of $3.4 million from a net liability of $4.8 million at March 31, 2018, resulting in an unrealized gain on derivatives of $1.4 million for the three months ended June 30, 2018.
Six Months Ended June 30, 2019 as Compared to Six Months Ended June 30, 2018
Oil and natural gas revenues. Our oil and natural gas revenues increased $13.4 million, or 3%, to $404.3 million for the six months ended June 30, 2019, as compared to $391.0 million for the six months ended June 30, 2018. Our oil revenues increased $28.9 million, or 9%, to $343.3 million for the six months ended June 30, 2019, as compared to $314.4 million for the six months ended June 30, 2018. The increase in oil revenues resulted from the 27% increase in our oil production to 6.5 million Bbl of oil for the six months ended June 30, 2019, as compared to 5.1 million Bbl of oil for the six months ended June 30, 2018. The increase in oil production was primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin. This increase was partially offset by a lower weighted average oil price realized for the six months ended June 30, 2019 of $53.20 per Bbl, a decrease of 14% as compared to $61.80 per Bbl realized for the six months ended June 30, 2018. Our natural gas revenues decreased by $15.5 million, or 20%, to $61.0 million for the six months ended June 30, 2019, as compared to $76.5 million for the six months ended June 30, 2018. The decrease in natural gas revenues resulted from a lower weighted average natural gas price realized for the six months ended June 30, 2019 of $2.25 per Mcf, a decrease of 33% as compared to $3.35 per Mcf realized for the six months ended June 30, 2018. This decrease was partially offset by the 19% increase in our natural gas production to 27.1 Bcf for the six months ended June 30, 2019, as compared to 22.8 Bcf for the six months ended June 30, 2018. 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 $19.7 million to $26.2 million, or just over four-fold, for the six months ended June 30, 2019, as compared to $6.5 million for the six months ended June 30, 2018. This increase was primarily attributable to (i) an increase in our third-party salt water gathering and disposal revenues to approximately $12.0 million for the six months ended June 30, 2019, as compared to approximately $3.0 million for the six months ended June 30, 2018, and (ii) an increase in natural gas gathering, transportation and processing revenues to approximately $11.0 million for the six months ended June 30, 2019, as compared to $3.4 million for the six months ended June 30, 2018.
Sales of purchased natural gas. Our sales of purchased natural gas were $20.2 million for the six months ended June 30, 2019. We had no sales of purchased natural gas for the six months ended June 30, 2018.

Realized gain (loss) on derivatives. Our realized net gain on derivatives was $4.4 million for the six months ended June 30, 2019, as compared to a realized net loss of $6.7 million for the six months ended June 30, 2018. We realized a net gain of $4.5 million related to our oil costless collar contracts for the six months ended June 30, 2019, resulting from oil prices that were below the floor prices of certain of our oil costless collar contracts. We realized net losses of $6.7 million from our oil and natural gas derivative contracts for the six months ended June 30, 2018, 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 an average gain on our oil derivatives of approximately $0.70 per Bbl produced during the six months ended June 30, 2019, as compared to an average loss of $1.34 per Bbl produced during the six months ended June 30, 2018. Our total oil volumes hedged for the six months ended June 30, 2019 represented 57% of our total oil production, as compared to 53% of our total oil production for the six months ended June 30, 2018. Our total natural gas volumes hedged for the six months ended June 30, 2019 represented 13% of our total natural gas production, as compared to 37% of our total natural gas production for the six months ended June 30, 2018.
Unrealized (loss) gain on derivatives. Our unrealized net loss on derivatives was $39.6 million for the six months ended June 30, 2019, as compared to an unrealized net gain of $11.8 million for the six months ended June 30, 2018. During the period from December 31, 2018 through June 30, 2019, the aggregate net fair value of our open oil and natural gas derivative contracts decreased to a net asset of approximately $10.3$4.1 million from a net asset of approximately $49.8 million at December 31, 2018, resulting in an unrealized loss on derivatives of approximately $39.6$45.7 million for the sixthree months ended June 30,March 31, 2019. During the period from December 31, 2017 through June 30, 2018, the aggregate net fair value of our open oil and natural gas derivative contracts increased from a net liability of approximately $15.2 million to a net liability of approximately $3.4 million, resulting in an unrealized gain on derivatives of approximately $11.8 million for the six months ended June 30, 2018.

Three Months Ended June 30, 2019March 31, 2020 as Compared to Three Months Ended June 30, 2018March 31, 2019
Production taxes, transportation and processing. Our production taxes and transportation and processing expenses increased $1.4$2.1 million, or 7%10%, to $21.5$21.7 million for the three months ended June 30, 2019,March 31, 2020, as compared to $20.1$19.7 million for the three months ended June 30, 2018. TheMarch 31, 2019. This increase was primarily attributable to the $1.3$1.5 million increase in transportation and processing fees to $6.3$7.6 million for the three months ended June 30, 2019,March 31, 2020, as compared to $5.0$6.1 million for the three months ended June 30, 2018,March 31, 2019, principally due to the 6%22% increase in our natural gas production to 13.416.7 Bcf of natural gas for the three months ended June 30, 2019,March 31, 2020, as compared to 12.713.7 Bcf of natural gas for the three months ended June 30, 2018.March 31, 2019. On a unit-of-production basis, our production taxes and transportation and processing expenses decreased 7%8% to $3.86$3.35 per BOE for the three months ended June 30, 2019,March 31, 2020, as compared to $4.17$3.65 per BOE for the three months ended June 30, 2018. TheMarch 31, 2019. This decrease was primarily attributable to the 20% increase in our total oil equivalent production to 6.5 million BOE for the three months ended March 31, 2020, as compared to 5.4 million BOE for the three months ended March 31, 2019, and lower production taxes on a per unit basis as a result of the decrease in the weighted average oil and natural gas prices realized between the two periods.
Lease operating. Our lease operating expenses increased $1.3decreased $0.3 million, or 5%1%, to $26.4$30.9 million for the three months ended June 30, 2019,March 31, 2020, as compared to $25.0$31.2 million for the three months ended June 30, 2018. The increaseMarch 31, 2019. This decrease was largely attributable to decreases in equipment rental and workover expenses of $1.7 million, as well as a decrease in saltwater disposal expenses of $4.3 million associated with connecting more wells to salt water disposal pipelines. These decreases were largely offset by increases in compression, repairs and maintenance and non-operated lease operatingother expenses of approximately $2.6 million for the three months ended June 30, 2019, as compared to the three months ended June 30, 2018. This increase was partially offset by$5.7 million. On a decrease in salt water trucking and disposal costs as more ofunit-of-production basis, our operated wells have been connected to salt water disposal pipelines. Our lease operating expenses decreased 9% on a unit-of-production basis17% to $4.72$4.77 per BOE for the three months ended June 30, 2019,March 31, 2020, as compared to $5.19$5.78 per BOE for the three months ended June 30, 2018, as a result ofMarch 31, 2019. This decrease was attributable to the 16%20% increase in our total oil equivalent production to 6.5 million BOE for the three months ended June 30, 2019,March 31, 2020, as compared to 5.4 million BOE for the three months ended June 30, 2018.March 31, 2019.

Plant and other midstream services operating. Our plant and other midstream services operating expenses increased $2.7$0.6 million, or 48%7%, to $8.4$10.0 million for the three months ended June 30, 2019,March 31, 2020, as compared to $5.7$9.3 million for the three months ended June 30, 2018.March 31, 2019. This increase was primarily attributable to (i) increased expenses associated with the Black River Processing Plant of $3.1 million for the three months ended June 30, 2019, as compared to $1.9 million for the three months ended June 30, 2018, (ii) increased expenses associated with our expanded commercial salt water disposal operations of $3.8$5.1 million for the three months ended June 30, 2019,March 31, 2020, as compared to $3.0$4.3 million for the three months ended June 30, 2018, and (iii) increased expenses associated with pipeline operations of $1.6 million for the three months ended June 30, 2019, as compared to $1.0 million for the three months ended June 30, 2018.March 31, 2019.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses increased $13.3$13.8 million, or 20%18%, to $80.1$90.7 million for the three months ended June 30, 2019,March 31, 2020, as compared to $66.8$76.9 million for the three months ended June 30, 2018. On a unit-of-production basis, our depletion, depreciation and amortization expenses increased 4% to $14.37 per BOE for the three months ended June 30, 2019, as compared to $13.87 per BOE for the three months ended June 30, 2018. TheMarch 31, 2019. This increase in our total depletion, depreciation and amortization expenses was primarily attributable to (i) the 16%20% increase in our total oil equivalent production to 5.66.5 million BOE for the three months ended June 30, 2019,March 31, 2020, as compared to 4.85.4 million BOE for the three months ended June 30, 2018,March 31, 2019, and (ii) increased depreciation expenses attributable to our midstream segment of approximately $3.8$4.8 million for the three months ended June 30, 2019,March 31, 2020, as compared to $2.3$3.7 million for the three months ended June 30, 2018.March 31, 2019. On a unit-of-production basis, our depletion, depreciation and amortization expenses decreased 2% to $14.01 per BOE for the three months ended March 31, 2020, as compared to $14.25 per BOE for the three months ended March 31, 2019. On a unit-of-production basis, the impact of the increases in total oil equivalent production and midstream depreciation expenses was largely offset by higher total proved oil and natural gas reserves at June 30, 2019,March 31, 2020, as compared to June 30, 2018,March 31, 2019, primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.Basin, was largely offset by the increase in total oil equivalent production for the three months ended March 31, 2020, as compared to the three months ended March 31, 2019.

Full-cost ceiling impairment. We use the full-cost method of accounting for our investments in oil and natural gas properties. Under this method, we are 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 the three months ended March 31, 2020 and 2019, the full-cost ceiling was higher than the capitalized costs of oil and natural gas properties, and, as a result, no impairment charge was necessary.

The unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended March 31, 2020 were $52.23 per Bbl and $2.30 per MMBtu, respectively.  If the unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended March 31, 2020 had been $42.42 per Bbl and $2.05 per MMBtu, respectively, while all other factors remained constant, our full-cost ceiling would have been impaired by approximately $550.0 million on a pro forma basis.  The aforementioned pro forma prices, as estimated for the twelve month period July 2019 through June 2020, were calculated using a 12-month unweighted arithmetic average of oil and natural gas prices, which included the oil and natural gas prices on the first day of the month for the 10 months ended April 2020, with the price for April 2020 being held constant for May and June 2020.  This pro forma excess of our net capitalized costs above the full-cost ceiling is attributable to a pro forma reduction of approximately $840.0 million in the estimated value, discounted at 10%, of our total proved oil and natural gas reserves, including a pro forma decrease in our estimated total proved reserves of approximately 8% from our estimated proved reserves at March 31, 2020, primarily attributable to certain proved undeveloped locations that would no longer be classified as proved undeveloped reserves using the pro forma prices. This calculation of the impact of lower commodity prices on our estimated total proved oil and natural gas reserves and our full-cost ceiling was prepared based on the presumption that all other inputs and assumptions are held constant with the exception of oil and natural gas prices. Therefore, this calculation strictly isolates the impact of commodity prices on our full-cost ceiling and proved reserves. The impact of prices is only one of several variables in the estimation of our proved reserves and full-cost ceiling and other factors could have a significant impact on our future proved reserves and the present value of future cash flows. The other factors that impact future estimates of proved reserves include, but are not limited to, extensions and discoveries, acquisitions of proved reserves, changes in drilling and completion and operating costs, drilling results, revisions due to well performance and other factors, changes in development plans and production, among others. There are numerous uncertainties inherent in the estimation of proved oil and natural gas reserves and accounting for oil and natural gas properties in subsequent periods, and this pro forma estimate should not be construed as indicative of our development plans or future results. 
General and administrative. Our general and administrative expenses increased $0.5decreased $2.1 million, or 3%11%, to $19.9$16.2 million for the three months ended June 30, 2019,March 31, 2020, as compared to $19.4$18.3 million for the three months ended June 30, 2018.March 31, 2019. The decrease in general and administrative expenses was primarily attributable to a decrease of $2.6 million in stock-based compensation expense related to our liability-based awards as a result of the decrease in the price of our common stock at March 31, 2020, as compared to December 31, 2019. This decrease was partially offset by decreased capitalized general and administrative expenses on certain qualifying projects between the two periods. Our general and administrative expenses decreased 11%26% on a unit-of-production basis to $3.56$2.51 per BOE for the three months ended June 30, 2019,March 31, 2020, as compared to $4.02$3.39 per BOE for the three months ended June 30, 2018, primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.March 31, 2019.
Interest expense. For the three months ended June 30, 2019,March 31, 2020, we incurred total interest expense of approximately $20.7$21.3 million. We capitalized approximately $2.6$1.4 million of our interest expense on certain qualifying projects for the three months ended June 30, 2019March 31, 2020 and expensed the remaining $18.1$19.8 million to operations. For the three months ended June 30, 2018,March 31, 2019, we incurred total interest expense

of approximately $10.6$19.6 million. We capitalized approximately $2.6$1.6 million of our interest expense on certain qualifying projects for the three months ended June 30, 2018March 31, 2019 and expensed the remaining $8.0$17.9 million to operations.
Total income tax provision. We recorded a total income tax expense of $12.9$40.0 million for the three months ended June 30, 2019,March 31, 2020, which differsdiffered from amounts computed by applying the U.S. federal statutory ratetax rates to pre-tax income due primarily to the impact of permanent differences between book and taxable income and state taxes, primarily in New Mexico. The effective tax income. Due to a variety of factors, including our significant net income in 2017 and 2018, our federal valuation allowance and a portion of our state valuation allowance were reversed at December 31, 2018, as the deferred tax assets were determined to be more likely than not to be utilized. As a portion of our state net operating loss carryforwards are not expected to be utilized before expiration, a valuation allowance will continue to be recognized until the state deferred tax assets are more likely than not to be utilized. At June 30, 2018, our deferred tax assets exceeded our deferred tax liabilities due to the deferred tax amounts generated by 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, 2018 due to uncertainties regarding the future realization of our deferred tax assets.
Six Months Ended June 30, 2019 as Compared to Six Months Ended June 30, 2018
Production taxes, transportation and processing. Our production taxes, transportation and processing expenses increased $3.3 million, or 9%, to $41.2 millionrate for the sixthree months ended June 30, 2019, as compared to $37.9 million for the six months ended June 30, 2018. The increase in production taxes, transportation and processing expensesMarch 31, 2020 was primarily attributable to the $2.8 million increase in our transportation and processing expenses for the six months ended June 30, 2019, as compared to the six months ended June 30, 2018, principally due to the 19% increase in our natural gas production to 27.1 billion Bcf of natural gas for the six months ended June 30, 2019, as compared to 22.8 billion Bcf of natural gas for the six months ended June 30, 2018. On a unit-of-production basis, our production taxes, transportation and processing expenses decreased 12% to $3.76 per BOE for the six months ended June 30, 2019, as compared to $4.26 per BOE for the six months ended June 30, 2018. The decrease was primarily attributable to lower production taxes on a per unit basis as a result of the decrease in weighted average oil and natural gas prices realized between the two periods.
Lease operating. Our lease operating expenses increased $10.4 million, or 22%, to $57.5 million for the six months ended June 30, 2019, as compared to $47.2 million for the six months ended June 30, 2018. The increase in lease operating expenses for the six months ended June 30, 2019, as compared to the six months ended June 30, 2018, was primarily attributable to an increase in costs of services and equipment, including salt water disposal costs in asset areas other than Wolf and Rustler Breaks (which are

serviced by San Mateo)24%. Our lease operating expenses on a unit-of production basis decreased 1% to $5.24 per BOE for the six months ended June 30, 2019, as compared to $5.30 per BOE for the six months ended June 30, 2018.
Plant and other midstream services operating. Our plant and other midstream services operating expenses increased $7.8 million, or 79%, to $17.7 million for the six months ended June 30, 2019, as compared to $9.9 million for the six months ended June 30, 2018. This increase was primarily attributable to (i) increased expenses associated with our expanded commercial salt water disposal operations of $8.1 million for the six months ended June 30, 2019, as compared to $5.2 million for the six months ended June 30, 2018, (ii) increased expenses associated with the Black River Processing Plant, which was expanded late in the first quarter of 2018, of $6.1 million for the six months ended June 30, 2019, as compared to $3.6 million for the six months ended June 30, 2018, and (iii) increased expenses associated with pipeline operations of $3.7 million for the six months ended June 30, 2019, as compared to $1.6 million for the six months ended June 30, 2018.
Depletion, depreciation and amortization. Our depletion, depreciation and amortization expenses increased $34.8 million, or 28%, to $157.0 million for the six months ended June 30, 2019, as compared to $122.2 million for the six months ended June 30, 2018. On a unit-of-production basis, our depletion, depreciation and amortization expenses increased 4% to $14.31 per BOE for the six months ended June 30, 2019, as compared to $13.74 per BOE for the six months ended June 30, 2018. The increase in our total depletion, depreciation and amortization expenses was primarily attributable to (i) the 23% increase in our total oil equivalent production to 11.0 million BOE for the six months ended June 30, 2019, as compared to 8.9 million BOE for the six months ended June 30, 2018, and (ii) the increase in depreciation expenses attributable to our midstream segment of approximately $9.3 million for the six months ended June 30, 2019, as compared to $5.2 million for the six months ended June 30, 2018. On a unit-of-production basis, the impact of the increases in total oil equivalent production and midstream depreciation expenses was largely offset by higher total proved oil and natural gas reserves at June 30, 2019, as compared to June 30, 2018, primarily attributable to our ongoing delineation and development drilling activities in the Delaware Basin.
General and administrative. Our general and administrative expenses increased $0.9 million, or 2%, to $38.2 million for the six months ended June 30, 2019, as compared to $37.3 million for the six months ended June 30, 2018. Primarily as a result of the 23% increase in total oil equivalent production for the six months ended June 30, 2019, as compared to the six months ended June 30, 2018, our general and administrative expenses decreased 17% on a unit-of-production basis to $3.48 per BOE for the six months ended June 30, 2019, as compared to $4.19 per BOE for the six months ended June 30, 2018.
Interest expense. For the six months ended June 30, 2019, we incurred total interest expense of approximately $40.2 million. We capitalized approximately $4.2 million of our interest expense on certain qualifying projects for the six months ended June 30, 2019 and expensed the remaining $36.0 million to operations. For the six months ended June 30, 2018, we incurred total interest expense of approximately $21.0 million. We capitalized approximately $4.5 million of our interest expense on certain qualifying projects for the six months ended June 30, 2018 and expensed the remaining $16.5 million to operations.
Total income tax provision. We recorded a total income tax expensebenefit of $11.8$1.0 million for the sixthree months ended June 30,March 31, 2019, and the effective tax rate was 33%, which differsdiffered from amounts computed by applying the U.S. federal statutory rate to the pre-tax incomeloss due primarily due to the impact of permanent differences between book and tax income. Due to a variety of factors, including our significant net income in 2017 and 2018, our federal valuation allowance and a portion of our state valuation allowance were reversed at December 31, 2018, as the deferred tax assets were determined to be more likely than not to be utilized.

We retained a full valuation allowance at June 30, 2018 due to uncertainties regarding the future realization of our deferred tax assets.loss.
Liquidity and Capital Resources
Our primary use of capital has been, and we expect will continue to be during the remainder of 20192020 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 for the remainder of 2019our 2020 capital expenditures primarily through a combination of cash on hand, operating cash flows, performance incentives in connection with the formation of San Mateo, I that were received in the first quarter of 2019, borrowings under the Credit Agreement (assuming availability under our borrowing base)base of $900.0 million) and borrowings under the San Mateo I’s revolving credit facility (the “San Mateo Credit Facility.Facility”) (assuming availability under the accordion feature of such facility to up to $400.0 million). In addition, in 2020, we expect to receive the remaining portion of the $50.0 million capital carry Five Point agreed to provide to us in conjunction with the formation of San Mateo II. 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 leasehold interests particularly in our non-core asset areas, the sale or joint venture of oil and natural gas mineral interests as well asand 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.
At June 30, 2019 and July 31, 2019, we had (i) $1.05 billion of outstanding 5.875% senior notes due 2026 (the “Notes”), (ii) $205.0 million in borrowings outstandingIn February 2020, the lenders under the Credit Agreement completed their review of our proved oil and (iii) approximately $13.6natural gas reserves at December 31, 2019, and, as a result, the borrowing base was affirmed at $900.0 million. We elected to increase the borrowing commitment from $500.0 million in outstanding

lettersto $700.0 million, and the maximum facility amount remained $1.5 billion. We also added two new banks to our lending group as part of credit issued pursuant tothis redetermination process. This February 2020 redetermination constituted the regularly scheduled May 1 redetermination. Borrowings under the Credit Agreement and San Mateo I had $240.0 million in borrowings outstanding under the San Mateo Credit Facility and approximately $16.2 million in outstanding letters of credit issued pursuantare limited to the San Mateolowest of the borrowing base, the maximum facility amount and the elected commitment. The Credit Facility.Agreement matures in October 2023. The Credit Agreement requires the Company to maintain a debt to EBITDA ratio, which is defined as debt outstanding (net of up to $50.0 million of cash or cash equivalents) divided by a rolling four quarter EBITDA calculation, of 4.00 or less. The Company believes that it was in compliance with the terms of the Credit Agreement at March 31, 2020.

By contractual agreement, the cash in the accounts held by our less-than-wholly-owned subsidiaries is not to be commingled with our other cash and is to be used only to fund the capital expenditures and operations of these less-than-wholly-owned subsidiaries.
In April 2019, the lenders under our Credit Agreement, led by Royal BankAt March 31, 2020, we had (i) $1.05 billion of Canada, completed their review of our proved oil and natural gas reserves at December 31, 2018, and as a result, the borrowing base was increased to $900.0outstanding 5.875% senior notes due September 2026 (the “Notes”), (ii) $315.0 million with the elected borrowing commitment remaining at $500.0 million. This April 2019 redetermination constituted the regularly scheduled May 1 redetermination. Borrowingsin borrowings outstanding under the Credit Agreement are limitedand (iii) approximately $46.0 million in outstanding letters of credit issued pursuant to the lowestCredit Agreement. Between March 31 and April 29, 2020, we borrowed an additional $30.0 million under the Credit Agreement.
At March 31, 2020, San Mateo had $307.5 million in borrowings outstanding under the San Mateo Credit Facility and approximately $9.0 million in outstanding letters of credit issued pursuant to the borrowing base, the maximum facility amountSan Mateo Credit Facility. The San Mateo Credit Facility includes an accordion feature, which provides for potential increases to up to $400.0 million, and the elected borrowing commitment.

At March 31, 2020, the lender commitments under the San Mateo Credit Facility led by The Bank of Nova Scotia, were increased to $325.0 million, using the accordion feature.$375.0 million. The San Mateo Credit Facility is guaranteed by San Mateo I’s subsidiaries, secured by substantially all of San Mateo I’s assets, including real property, and is non-recourse with respect to Matador and its wholly-owned subsidiaries, as well as San Mateo II.II and its subsidiaries. The San Mateo Credit Facility requires San Mateo I to maintain a debt to EBITDA ratio, which is defined as total consolidated funded indebtedness outstanding (as defined in the San Mateo Credit Facility) divided by a rolling four quarter EBITDA calculation, of 5.00 or less, subject to certain exceptions. The San Mateo Credit Facility also requires San Mateo I to maintain an interest coverage ratio, which is defined as a rolling four quarter EBITDA calculation divided by San Mateo I’s consolidated interest expense for such period, of 2.50 or more. The Company believes that San Mateo I was in compliance with the terms of the San Mateo Credit Facility at March 31, 2020.

2020 Capital Expenditure Budget
During the secondfirst quarter of 2019,2020, the oil and natural gas industry witnessed an abrupt and significant decline in oil prices from $63 per Bbl in early January to just above $20 per Bbl in late March. This sudden decline in oil prices was attributable to two primary factors: (1) the precipitous decline in global oil demand resulting from the worldwide spread of COVID-19 and (2) a sudden, unexpected increase in global oil supply resulting from actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts by members of OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria. Primarily as a result of these unexpected events and the resulting declines in oil prices, Matador has significantly modified its 2020 operational plan.
We began 2020 operating six drilling rigs in the Delaware Basin, as we continued ourto 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 2019 operatinghad originally planned to operate these six drilling rigs in the Delaware Basin throughout 2020. As a result of the events noted above, however, we released one operated drilling rig from our Wolf asset area in Loving County, Texas late in the first quarter of 2020, and continued to do so at June 30, 2019. Duringwe released a second operated drilling rig from the Greater Stebbins Area in late April 2020. We anticipate releasing one additional drilling rig by the end of the second quarter these six operated drilling rigs were deployed across our Delaware Basin asset areas, but with an increased focus on the Antelope Ridge asset area. Weof 2020. Thereafter, we expect to operate sixthree drilling rigs in the Delaware Basin throughout the remainder of 2019, with four2020. Two of these rigs operating betweenare anticipated to operate in our Stateline asset area in Eddy County, New Mexico, and the third rig is expected to operate primarily in the Rustler Breaks and Antelope Ridge asset areas, one rig operating in the Wolf and Jackson Trust asset areas and one rig operating in the Arrowhead, Ranger and Twin Lakes asset areas, although this rig, in particular, is expected to operate in the Greater Stebbins Area for most of the remainder of 2019. We expect that developmentareas.
As a result of our Delaware Basin assets will beplans to reduce our operated drilling program from six to three rigs by the primary focusend of our operations and capital expenditures for the remainder of 2019.
During the second quarter of 2019,2020, on April 29, 2020, we also finisheddecreased the range of our nine-well program in South Texas, which we began in October 2018, including eight Eagle Ford shale wells and one Austin Chalk well. The rig used to drill these nine wells was released in early February 2019, and we have no additional operated drilling activities planned in the Eagle Ford shale for the remainder of 2019.
2019 Capital Expenditure Budget
At July 31, 2019, our 2019 estimatedanticipated full-year 2020 capital expenditures for drilling, completing and equipping wells (“D/C/E”) remained $640from $690.0 to $680$750.0 million as originally estimated. As a result of improved drilling and completion and capital efficiencies, an accelerated pace of activity and our expectations for acquiring additional working interests primarily through acreage trades in certainto $440.0 to $500.0 million. The range of our operated wells throughout 2019, we now expect to complete and turn to sales four gross (6.8 net) additional operated wells in 2019, as compared to our original 2019 plan, which includes four gross (3.0 net) additional wells resulting from an accelerated pace of drilling and completion activity in 2019 and 3.8 net additional wells attributable to increased working interests acquired or anticipated to be acquired in certain operated wells during the course of the year. Due to the lower well costs and facilities savings achieved thus far in 2019, however, at July 31, 2019, we anticipate we should be able to deliver these additional well completions within our originally budgeted estimates for D/C/Efull-year 2020 capital expenditures of $640 to $680 million. In addition, at July 31, 2019, we have no plans to add a seventh rig to our 2019 drilling program.
On July 31, 2019, we increased our anticipated 2019for midstream capital expenditures from $55remained $85.0 to $75$105.0 million, to $70 to $90 million, primarily for capital expenditures necessary to accommodate new customers and increased commitments from existing customers. During the first six months of 2019, San Mateo received an increased natural gas gathering and processing commitment from an existing natural gas customer and obtained a significant additional acreage dedication and a salt water disposal well permit from an existing salt water customer. In addition, San Mateo is in negotiations with other third parties to provide oil, natural gas and salt water gathering services, natural gas processing services and salt water disposal services. In order to provide the midstream services under these executed and anticipated agreements, San Mateo expects to undertake additional projects that will require added compression, oil, natural gas and water gathering lines and water disposal infrastructure not originally budgeted for in 2019. At July 31, 2019, San Mateo had also entered into an agreement to acquire an existing commercial salt water disposal well and facility, a salt water disposal permit and surface acreage near the Greater Stebbins Area. The anticipated total 2019 midstream capital expenditures of $70 to $90 million reflectwhich reflects our proportionate share of San Mateo’s estimated 2019 capital expenditures of $190.0 million to $235.0 million and also accountaccounts for the remaining portions of the $50$50.0 million capital carry that Five Point agreed to provide to us in conjunction with the formation of San Mateo II.

Substantially all of our remaining 2019these 2020 estimated capital expenditures will be allocated to (i) the further delineation and development of our leasehold position, (ii) the continued construction of midstream assets and (iii) our participation in certain non-operated well opportunities in the Delaware Basin, with the exception of amounts allocated to limited operations in our South Texas and Haynesville shale positions to maintain and extend leases and to participate in certain non-operated well opportunities.
To narrow any potential difference between our 20192020 capital expenditures and operating cash flows, we may divest portions of our non-core assets, particularly in the Haynesville shale and in parts of our South Texas and Haynesville shale positions (as we did in 2019, converting $21.9 million of non-core assets to cash), as well as consider monetizing other assets, such as certain mineral, royalty and midstream interests, as value-creating opportunities arise. For example, in the second quarter and early in the third quarter of 2019,In addition, we successfully closed and received approximately $22 million in proceeds attributable to the sale of portions of our properties, primarily in our South Texas and Haynesville shale positions, as well as a small portion of our leasehold in a non-operated area of the Delaware Basin. We intend to continue evaluating the opportunistic acquisition of acreage and mineral interests, principally in the Delaware Basin, during 2019.2020. These monetizations, divestitures and expenditures are opportunity-specific, and purchase price multiples and per-acre prices can vary significantly based on the asset or prospect. As a result, it is difficult to estimate these 20192020 monetizations, divestitures and capital expenditures with any degree of certainty; therefore, we have not provided estimated proceeds related to monetizations or divestitures or estimated capital expenditures related to acreage and mineral acquisitions for 2019.2020.
Our 20192020 capital expenditures may be adjusted as business conditions warrant and the amount, timing and allocation of such expenditures isare 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, the ability of our joint venture partners to meet their 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. In addition, we attempt to avoid long-term service agreements where possible to minimize ongoing future commitments.
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 20192020 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 have 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 realized oil, natural gas and NGL prices for the remainder of 20192020 and the hedges we currently have in place. As noted above, the oil and natural gas industry witnessed an abrupt and significant decline in oil prices

during the first quarter of 2020. As of April 29, 2020, WTI oil prices were below $20 per Bbl and were anticipated to remain below $30 per Bbl for the remainder of 2020. For further discussion of our expectations of such commodity prices, see “— General Outlook and Trends” below. We use commodity derivative financial instruments at times to mitigate our exposure to fluctuations in oil, natural gas and NGL prices and to partially offset reductions in our cash flows from operations resulting from declines in commodity prices. 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, 2019.instruments.

Cash Flows Provided by Operating Activities
Net cash provided by operating activities decreased $59.7increased $50.1 million to $194.5$109.4 million for the sixthree months ended June 30, 2019March 31, 2020 from $254.2$59.2 million for the sixthree months ended June 30, 2018.March 31, 2019. Excluding changes in operating assets and liabilities, net

cash provided by operating activities increased to $255.5$134.3 million for the sixthree months ended June 30, 2019March 31, 2020 from $251.0$117.7 million for the sixthree months ended June 30, 2018,March 31, 2019, primarily attributable to the increase in our totalhigher oil equivalentand natural gas production, which was partially offset by the decrease inlower realized oil and natural gas prices betweenfor the two periods.three months ended March 31, 2020, as compared to the three months ended March 31, 2019. Changes in our operating assets and liabilities between the two periods resulted in a net decreaseincrease of approximately $64.2$33.6 million in net cash provided by operating activities for the sixthree months ended June 30, 2019,March 31, 2020, as compared to the sixthree months ended June 30, 2018.March 31, 2019.
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 the Organization of Petroleum Exporting Countries (OPEC),OPEC+ and other large state-owned oil producers, weather, infrastructure capacity to reach markets and other variable factors significantly impact the prices of oil and natural gas. Furthermore, the continued effect of COVID-19 and the corresponding decline in oil demand will also significantly impact the prices we receive for our oil production. 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 NGL prices.
Cash Flows Used in Investing Activities
Net cash used in investing activities decreasedincreased by $98.9$33.3 million to $394.7$248.2 million for the sixthree months ended June 30, 2019March 31, 2020 from $493.6$214.9 million for the sixthree months ended June 30, 2018.March 31, 2019. This decreaseincrease in net cash used in investing activities is due to an increase in part tomidstream capital expenditures of approximately $40.1 million, which was partially offset by a decrease of $71.7$8.3 million in oil and natural gas properties capital expenditures for the sixthree months ended June 30, 2019,March 31, 2020, as compared to the sixthree months ended June 30, 2018.March 31, 2019. Cash used for midstream capital expenditures for the three months ended March 31, 2020 was primarily attributable to the expansion of the Black River Processing Plant and midstream facilities in the Greater Stebbins Area and the Stateline asset area. Cash used for oil and natural gas properties capital expenditures for the sixthree months ended June 30, 2019March 31, 2020 was primarily attributable to our operated and non-operated drilling and completion activities in the Delaware Basin and in South Texas. The remaining decrease in net cash used in investing activities was primarily attributable to a decrease in cash used for midstream capital expenditures of $14.2 million, primarily related to capital expenditures for San Mateo, and an increase of $13.9 million in proceeds from the sale of assets.Basin.

Cash Flows Provided by Financing Activities
Net cash provided by financing activities decreasedincreased by $79.4$12.1 million to $201.0$130.5 million for the sixthree months ended June 30, 2019March 31, 2020 from $280.4$118.4 million for the sixthree months ended June 30, 2018. This decrease in netMarch 31, 2019. During the three months ended March 31, 2020, our primary sources of cash provided byfrom financing activities is dueincluded borrowings under the Credit Agreement of $60.0 million, borrowings under the San Mateo Credit Facility of $19.5 million and net contributions related to the formation of San Mateo I and from non-controlling interest owners in part to a net increase inless-than-wholly-owned subsidiaries of $53.2 million. During the three months ended March 31, 2019, we had borrowings under our Credit Agreement of $165.0$100.0 million, betweenas well as net contributions related to the two periods, offset by a reduction in proceeds from the issuanceformation of common stock of $226.6 millionSan Mateo I and a decrease of $34.1 million in contributions from non-controlling interest owners in less-than-wholly-owned subsidiaries.subsidiaries of $18.7 million.
See Note 4 to the unaudited condensed consolidated financial statements in this Quarterly Report for a summary of our debt, including the Credit Agreement, the San Mateo Credit Facility and the Notes.
Non-GAAP Financial Measures
We define Adjusted EBITDA as earnings before interest expense, income taxes, depletion, depreciation and amortization, accretion of asset retirement obligations, property impairments, unrealized derivative gains and losses, certain other non-cash items and non-cash stock-based compensation expense, and net gain or loss on asset sales and inventory impairment. Adjusted EBITDA is not a measure of net income (loss) or cash flows as determined by GAAP. Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies.
Management believes Adjusted EBITDA is necessary because it allows us to evaluate our operating performance and compare the results of operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in calculating Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which certain assets were acquired.
Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss) 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 and net cash provided by operating activities, respectively.

This decreaseincrease in net income attributable to Matador Resources Company shareholders is primarily attributable to (i)an increase of $182.1 million in unrealized gain on derivatives, from an unrealized loss of $45.7 million for the three months ended March 31, 2019 to an unrealized gain of $136.4 million for the three months ended March 31, 2020. This increase was partially offset by a $13.3 million increase in depletion, depreciation and amortization expenses, (ii) a $10.1 million increase in interest expense and (iii) a $12.9$41.0 million increase in the deferred income tax provision between the two periods. This decrease was partially offset by an increase of $3.7 million from realized loss to realized gain on derivatives and an increase of $4.7 million in unrealized gain on derivatives.
Net income attributable to Matador Resources Company shareholders decreased by $99.9 million to $19.8 million for the six months ended June 30, 2019, as compared to $119.7 million for the six months ended June 30, 2018. This decrease inprovision. In addition, net income attributable to Matador Resources Company shareholders is primarily attributable to (i) a $51.4 million decrease from unrealized gain to unrealized loss on derivatives, (ii) a $34.8 million increase in depletion, depreciation and amortization expenses, (iii) a $19.5 million increase in interest expense and (iv) an $11.8 million increase in the deferred income tax provision between the two periods.

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, 2019,March 31, 2020, the material off-balance sheet arrangements and transactions that we have entered into include (i) non-operated drilling commitments, (ii) termination obligations under drilling rig contracts, (iii) firm transportation, gathering, processing and disposal commitments and (iv)(iii) 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, transportation and disposal 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.

General Outlook and Trends
In 2018During the first quarter of 2020, the oil and 2019,natural gas industry witnessed an abrupt and significant decline in oil prices generally improved from the lower prices we experienced in 2016 and 2017, although oil prices remained significantly below their most recent highs in 2014.prices. For the three months ended June 30, 2019,March 31, 2020, oil prices averaged $59.96$45.78 per Bbl, ranging from a high of $66.30$63.27 per Bbl in early January to a low of $20.09 per Bbl in late April to a low of $51.14 per Bbl in mid-June,March, based upon the NYMEX West Texas IntermediateWTI oil futures contract price for the earliest delivery date. This sudden decline in oil prices was attributable to two primary factors: (1) the precipitous decline in global oil demand resulting from the worldwide spread of COVID-19 and (2) a sudden, unexpected increase in global oil supply resulting

from actions initiated by Saudi Arabia to increase its oil production to world markets following the failure of efforts by members of OPEC+ to agree on coordinated production cuts at their March 6, 2020 meetings in Vienna, Austria.
As noted previously in this Quarterly Report, Matador has significantly modified its 2020 operational plan primarily as a result of these unexpected events and the resulting decline in oil prices. We began 2020 operating six drilling rigs in the Delaware Basin but plan to reduce our operated drilling program from six to three drilling rigs by the end of the second quarter of 2020. Thereafter, we expect to operate three drilling rigs in the Delaware Basin throughout the remainder of 2020, but we are prepared to reduce our drilling activities further should conditions warrant. At April 29, 2020, the general outlook for the oil and natural gas industry for the remainder of 2020 remains highly uncertain, and we can provide no assurances as to when the economic disruptions resulting from COVID-19 and the corresponding decline in oil demand may begin to improve. Until such time, however, we anticipate that oil prices will remain well below the prices realized in 2019.
We realized a weighted average oil price of $56.51$45.87 per Bbl ($56.8648.81 per Bbl including realized gains from oil derivatives) for our oil production for the three months ended June 30, 2019,March 31, 2020, as compared to $61.44$49.64 per Bbl ($60.5250.72 per Bbl including realized lossesgains from oil derivatives) for our oil production for the three months ended June 30, 2018.March 31, 2019. At July 31, 2019,April 29, 2020, the NYMEX West Texas IntermediateWTI oil futures contract for the earliest delivery date had decreased significantly from the average price for the secondfirst quarter of 2019,2020, settling at $58.58$15.06 per Bbl, which was also a significant decrease as compared to $68.76 per Bbl$63.50 at July 31, 2018.April 29, 2019.
Natural gas prices were significantly lower in the first quarter of 2020, as compared to the first quarter of 2019. For the three months ended June 30, 2019,March 31, 2020, natural gas prices averaged $2.51$1.87 per MMBtu, ranging from a high of approximately $2.71$2.20 per MMBtu in early AprilJanuary to a low of approximately $2.19$1.60 per MMBtu in late June,March, 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 $1.64$1.70 per Mcf (with no realized gains or losses from natural gas derivatives) for our natural gas production (including revenues attributable to NGLs) for the three months ended June 30, 2019,March 31, 2020, as compared to $3.38$2.85 per Mcf (with no($2.84 with realized gains or losses from natural gas derivatives) for our natural gas production (including revenues attributable to NGLs) for the three months ended June 30, 2018.March 31, 2019. At July 31, 2019,April 29, 2020, the NYMEX Henry Hub natural gas futures contract price for the earliest delivery date had decreasedincreased from the average price forend of the secondfirst quarter of 2019,2020, settling at $2.23$1.87 per MMBtu, which was also a decrease as compared to $2.78$2.59 per MMBtu at July 31, 2018.April 29, 2019.
The prices we receive for oil, natural gas and NGLs heavily influence our revenue, profitability, cash flow available for capital expenditures, access to capital and future rate of growth. Oil, natural gas and NGL prices are subject to wide fluctuations in response to relatively minor changes in supply and demand. Historically, the markets for oil, natural gas and NGLs have been volatile, and these markets will likely continue to be volatile in the future. Declines in oil, natural gas or NGL prices not only reduce our revenues, but could also reduce the amount of oil, natural gas and NGLs we can produce economically, and, as a result, could have an adverse effect on our financial condition, results of operations, cash flows and reserves.reserves and our ability to comply with the leverage ratio covenant under our Credit Agreement. We are uncertain if or when oil and natural gas prices may rise from their current levels, and, in fact, oil and natural gas prices may decrease in future periods. See “Risk Factors — Our Success Is Dependent on the Prices of Oil and Natural Gas. Low Oil and Natural Gas Prices and the Continued Volatility in These Prices May Adversely Affect Our Financial Condition and Our Ability to Meet Our Capital Expenditure Requirements and Financial Obligations.” in the Annual Report.
From time to time, we use derivative financial instruments to mitigate our exposure to commodity price risk associated with oil, natural gas and NGL 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 NGL 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 ourthe Credit Agreement and through the capital markets.
During April 2020, we restructured a portion of our then-existing 2020 WTI oil hedges, providing additional revenue protection should oil prices remain at currently depressed levels for the remainder of 2020 or should further market disruptions occur. As a result of these modifications, we almost doubled our oil volumes hedged for the period from April through December 2020. At April 29, 2020, we had approximately 10.3 million Bbl of oil hedged for the period from April through December 2020. These hedges include approximately 7.6 million Bbl of fixed-price oil swaps at a weighted average price of approximately $35 per Bbl and 2.3 million Bbl of oil collars with a weighted average floor price of approximately $48 per Bbl and a weighted average ceiling price of approximately $66 per Bbl. We also have approximately 0.4 million Bbl in oil put options at a weighted average price of approximately $48 per Bbl for the period from April through June 2020. In addition, during April 2020, we added approximately 5.5 million Bbl of oil swaps at a weighted average price of approximately $35 per Bbl for 2021. We also added natural gas collars for November and December 2020 for approximately 3.2 million MMBtu and for the first quarter of 2021 for approximately 4.8 million MMBtu, each with a weighted average floor price of approximately $2.52 per MMBtu and a weighted average ceiling price of approximately $3.71 per MMBtu.
The prices we receive for our oil and natural gas production often reflect a discount to the relevant benchmark prices, such as the NYMEX West Texas IntermediateWTI oil price or the NYMEX Henry Hub natural gas price. The difference between the benchmark price and the price we receive is called a differential. At June 30, 2019,March 31, 2020, most of our oil production from the Delaware Basin was

sold based on prices established in Midland, Texas, andTexas. For most of the first nine months of 2019, almost all 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 second quarterTexas, and portions of 2018, the price differentials for oil sold in Midland andour natural gas are still sold atbased on Waha compared to the benchmark prices for oil and natural gas, respectively, began to widen significantly and continued to widen throughout most of the year. These widening basis differentials negatively impacted our oil and natural gas revenues in 2018.
During 2018, the Midland-Cushing (Oklahoma) oil price differential increased substantially from essentially no difference in the first quarter to as much as $16.00 per Bbl in late September but narrowed to about $5.00 per Bbl at the

beginning of 2019. The Midland-Cushing (Oklahoma) oil price differential narrowed further to less than $1.00 per Bbl during the first quarter of 2019 but widened again during the second quarter to levels experienced at the beginning of the year. The Midland-Cushing (Oklahoma) oil price differential has narrowed again early in the third quarter of 2019 and may become positive in the future, although it is possible that this differential could widen further at certain times during the remainder of 2019.
Our realized price for our Delaware Basin natural gas production is exposed to the Waha-Henry Hub basis differential. This natural gas price differential increased significantly throughout 2018 from about $0.50 per MMBtu at the beginning of the year to between $1.00 and $2.00 per MMBtu for most of 2018, but reaching highs of greater than $4.00 per MMBtu for a brief period nearprices. At the end of the year. The natural gas price differential narrowed to between $1.00 and $2.00 per MMBtu at the beginning ofSeptember 2019, and remained there throughout much of the first quarter.
The natural gas basis differentials widened significantly in April 2019 for a short period of time, including a few days when natural gas was being sold at Waha for negative prices as high as ($7.00) to ($9.00) per MMBtu on a daily market basis, resulting, in part, from a number of simultaneous outages and maintenance projects impacting major pipelines in the area. Natural gas prices at Waha were positive for most of the latter part of April 2019, but daily market prices for natural gas sold at Waha reached negative levels of ($2.00) to ($3.00) per MMBtu in late May. During the second quarter of 2019, the average daily Waha natural gas price was ($0.07) per MMBtu. In response to these basis differentials, we temporarily shut in certain high gas-oil ratio wells and took other actions to mitigate the impact of these negative prices on our results. Daily market prices for natural gas sold at Waha were positive for the month of July, although prices at Waha remained well below Henry Hub prices.
The majority of our Delaware Basin natural gas production is expected to remain exposed to the Waha-Henry Hub basis differentials until early in the fourth quarter of 2019, whenhowever, the Kinder Morgan Gulf Coast Express Pipeline Project (“GCX(the “GCX Pipeline”) is expected to becomebecame operational. We have secured firm natural gas transportation and sales on the GCX Pipeline for an average of approximately 110,000 to 115,000 MMBtu per day at a natural gas price based upon Houston Ship Channel pricing.
After a lengthy period beginning in the second quarter of 2018 in which the Midland-Cushing (Oklahoma) oil price differential was negative, reaching as high as ($16.00) per Bbl in late September 2018, this oil price differential became positive late in the third quarter of 2019 and remained positive into the first quarter of 2020. With the abrupt decline in oil prices during the first quarter of 2020, however, the Midland-Cushing (Oklahoma) oil price differential experienced significant volatility in April 2020. At April 29, 2020, this oil price differential was approximately $2.50 per Bbl, despite being approximately ($6.00) per Bbl earlier in April. It is possible that the differential could turn negative again at certain times during the remainder of 2020. At April 29, 2020, we had derivative contracts in place to mitigate our exposure to this Midland-Cushing (Oklahoma) oil price differential on a portion of our anticipated oil production for the remainder of 2020 and throughout 2021 and 2022.
In addition, as a result of oil futures prices being significantly higher than spot prices for oil, the monthly “roll,” which typically has minimal impact on our realized oil pricing, is expected to be significant and negative during the second quarter of 2020. As a result, our weighted average oil price differential relative to the WTI benchmark price is anticipated to be negative and in the range of ($6.00) to ($9.00) per Bbl in the second quarter of 2020, inclusive of the monthly roll and transportation costs.
Our realized prices for a portion of our Delaware Basin natural gas production are exposed to the Waha-Henry Hub basis differential. This Waha basis differential has increased significantly over the past two years, including a few days in April 2019 when natural gas was being sold at the Waha hub for negative prices as high as ($7.00) to ($9.00) per MMBtu on a daily market basis. During the second half of 2019, the Waha basis differentials improved, and natural gas prices at the Waha hub averaged approximately $1.00 per MMBtu for the final six months of the year. Despite improving during the second half of 2019, beginning in the fourth quarter, the Waha basis differential widened further at times, and natural gas prices at the Waha hub were slightly negative on certain days in late December 2019. In early 2020, the Waha basis differential continued to deteriorate, and natural gas prices at the Waha hub were negative on certain days in April 2020. However, the Waha basis differential narrowed in late April 2020, with the futures market indicating Waha basis differentials between ($0.30) and ($0.60) per MMBtu throughout the remainder of 2020 as of late April.
Beginning in late September 2019, as the GCX Pipeline became operational, we began selling a majority of our produced Delaware Basin natural gas at Houston Ship Channel pricing, and we have realized an improvement in the natural gas pricing received despite higher transportation charges incurred to transport the natural gas to the Gulf Coast. Further, approximately 23%29% of our reported natural gas production in the secondfirst quarter of 20192020 was attributable to the Haynesville and Eagle Ford shale plays, which are not exposed to Waha pricing. In addition, as a two-stream reporter, most of our natural gas volumes in the Delaware Basin are processed for NGLs, resulting in a further reduction in the reported natural gas volumes exposed to Waha pricing.
These widening oil and natural gas basis differentials are largely attributable to industry concerns regarding oil storage capacity and the near-term sufficiency of pipeline takeaway capacity for oil, natural gas and NGL production in the Delaware Basin. At July 31, 2019,April 29, 2020, we had not experienced oil storage concerns or material pipeline-related interruptions to our oil, natural gas or NGL production. During the third quarter of 2018,In certain recent periods, shortages of NGL fractionation capacity were experienced by certain operators in the Delaware Basin and elsewhere.Basin. Although we did not encounter such fractionation capacity problems, then and do not expect to encounter such problems going forward, we can provide no assurances that such problems will not arise. If we do experience any interruptions with takeaway capacity, oil storage or NGL fractionation, our oil and natural gas revenues, business, financial condition, results of operations and cash flows could be adversely affected.
We anticipate that the volatility in these oil and natural gas price differentials could persist throughout much of the remainder of 20192020 or longer until additional oil and natural gas pipeline capacity from West Texas to the Texas Gulf Coast and other end markets is completed.completed and as the balance between oil supply and demand is restored. We can provide no assurances as to how long these volatile differentials may persist, and as noted above, these price differentials could widen furtherdeteriorate in future periods. Should we experience future periods of negative pricing for natural gas as we did during the second quarter of 2019, we may temporarily shut in certain high gas-oil ratio wells and take other actions to mitigate the impact on our realized natural gas prices and results. In addition, we have no derivative contracts in place to mitigate our exposure to these natural gas price differentials during 2020.
In addition to concerns regarding oil and natural gas prices and basis differentials, the remainderdestruction of 2019global oil demand resulting from decline in economic activity associated with COVID-19, in conjunction with the recent actions initiated by Saudi Arabia to increase its oil production to world markets, has led to a significant oversupply of oil worldwide. On April 10, 2020, the members of OPEC+ (led by Saudi Arabia) reversed course and have limitedannounced their intentions to reduce oil basis hedges in placeproduction

significantly for the remainder of 2020 and into 2021 and 2022. It is uncertain, however, to what degree these production cuts may restore the balance between oil supply and demand, and most oil and natural gas industry observers remain skeptical that oil prices can improve substantially until oil demand begins to improve, most likely as a result of the “re-opening” of the world economy as concerns surrounding COVID-19 begin to subside.
In the near term, and certainly through the second quarter of 2020, there is a significant risk that oil production in the United States may exceed available oil storage capacity. Should this occur, we may be required by our oil purchasers to shut in a portion or all of our oil production for a period of time. Further, the concern over available oil storage capacity may also result in lower oil prices, and as a result, we may elect to shut in or curtail certain volumes of our oil production temporarily rather than sell the oil at further depressed prices. At April 29, 2020, we had determined to voluntarily curtail or shut in portions of our Delaware Basin and Eagle Ford shale oil production in May 2020 and will likely curtail and shut in portions of our oil production during June as well. As most of our natural gas production in the Delaware Basin is associated with oil production, portions of our natural gas production will also be curtailed or shut in. When shut-in wells resume production, they may not produce at their previous rates, and we may be required to expend capital to improve their production. We can provide no assurances as to whether additional portions of our oil production may be shut in or curtailed in the future or how long these periods may persist.
Further, if oil prices remain at their current depressed levels during the second quarter of 2020, we anticipate that we could realize a full-cost ceiling impairment to the net capitalized value of our oil and natural gas properties. In determining whether a full-cost ceiling impairment existed at March 31, 2020, we estimated the value, discounted at 10%, of our total proved oil and natural gas reserves using the unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended March 31, 2020 as required under the guidelines established by the SEC, which were $52.23 per Bbl and $2.30 per MMBtu, respectively. No full cost ceiling impairment was required at March 31, 2020. If the unweighted arithmetic average of oil and natural gas prices as of the first day of each month for the trailing 12-month period ended March 31, 2020 had been $42.42 per Bbl and $2.05 per MMBtu, respectively, while all other factors remained constant, our full-cost ceiling would have been impaired by approximately $550.0 million on a pro forma basis. The aforementioned pro forma prices, as estimated for the twelve month period July 2019 through June 2020, were calculated using a 12-month unweighted arithmetic average of oil and natural gas prices, which included the oil and natural gas prices on the first day of the month for the 10 months ended April 2020, with the price for April 2020 being held constant for May and June 2020. This pro forma excess of our net capitalized costs above the full-cost ceiling is attributable to a pro forma reduction of  approximately $840.0 million in the estimated value, discounted at 10%, of our total proved oil and natural gas reserves, including a pro forma decrease in our estimated total proved reserves of approximately 8% from our estimated proved reserves at March 31, 2020, primarily attributable to certain proved undeveloped locations that would no longer be classified as proved undeveloped reserves using the pro forma prices. This calculation of the impact of lower commodity prices on our estimated total proved oil and natural gas reserves and our full-cost ceiling was prepared based on the presumption that all other inputs and assumptions are held constant with the exception of oil and natural gas prices. Therefore, this calculation strictly isolates the impact of commodity prices on our full-cost ceiling and proved reserves. The impact of prices is only one of several variables in the estimation of our proved reserves and full-cost ceiling and other factors could have a significant impact on our future proved reserves and the present value of future cash flows.  The other factors that impact future estimates of proved reserves include, but are not limited to, extensions and discoveries, acquisitions of proved reserves, changes in drilling and completion and operating costs, drilling results, revisions due to well performance and other factors, changes in development plans and production, among others.  There are numerous uncertainties inherent in the estimation of proved oil and natural gas reserves and accounting for oil and natural gas properties in subsequent periods and this pro forma estimate should not be construed as indicative of our development plans or future results. 
Our oil and natural gas exploration, development, production, midstream and related operations are subject to extensive federal, state and local laws, rules and regulations. The regulatory burden on the oil and natural gas industry increases our cost of doing business and affects our profitability. Because these laws, rules and regulations are frequently amended or reinterpreted and new laws, rules and regulations are proposed or promulgated, we are unable to predict the future cost or impact of complying with the laws, rules and regulations to which we are, or will become, subject. For example, in early 2019 and 2020, separate bills were introduced in the New Mexico Senate proposing to add a surtax on natural gas processors and proposing to place a moratorium on hydraulic fracturing. In 2019, New Mexico’s governor also signed an executive order requiring a regulatory framework to ensure reductions of methane emissions. Although thesuch bills relating to the moratorium on hydraulic fracturing and the tax on natural gas processors werehave not passed, in the most recent legislative session, these and other laws, rules and regulations, including any federal legislation, regulations or orders intended to limit or restrict oil and natural gas operations on federal lands, if enacted, could have an adverse impact on our business, financial condition, results of operations and cash flows. In addition, certain segments of the investor community have recently expressed negative sentiment towards investing in the oil and natural gas industry, recent equity returns in the sector versus other industry sectors have led to lower oil and natural gas representation in certain key equity market indices and some investors, including certain pension funds, university endowments and family foundations, have stated policies to reduce or eliminate their investments in the oil and natural gas sector based on social and environmental considerations.

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 NGL price declines, however, drilling additional oil or natural gas wells may not be 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. See “Risk Factors — Our Exploration, Development, Exploitation and Midstream Projects Require Substantial Capital Expenditures That May Exceed Our Cash Flows from Operations and Potential Borrowings, and We May Be Unable to Obtain Needed Capital on Satisfactory Terms, Which Could Adversely Affect Our Future Growth.” in the Annual Report.
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, 2018,2019, 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 NGLs 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 NGL prices. Traditional costless collars provide us with downside price protection through the purchase of a put option that 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 Companyus with downside price protection through the purchase of a put option, but they also allow the Companyus 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.us. 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.
In response to the decline in the price of oil, in April 2020 we repurchased the call options on certain existing open oil costless collars and kept the remaining put options, exchanged certain existing open oil costless collars and added oil swaps.
We record all derivative financial instruments at fair value. The fair value of our derivative financial instruments is determined using purchase and sale information available for similarly traded securities. At June 30, 2019,March 31, 2020, The Bank of Nova Scotia and BMO Harris Financing (Bank of Montreal) (or affiliates thereof) were the counterparties for all of our derivative instruments. At April 29, 2020, The Bank of Nova Scotia, BMO Harris Financing (Bank of Montreal) and SunTrustTruist Bank (or affiliates thereof) were the counterparties for all of our derivative instruments. We have considered the credit standing of the counterparties in determining the fair value of our derivative financial instruments. 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, 2019.instruments.

Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this Quarterly Report, we evaluated the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of June 30, 2019March 31, 2020 to ensure that (i) information required to be disclosed in the reports it files and submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that (ii) information required to be disclosed under the Exchange Act is accumulated and communicated to the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
Changes in Internal Control over Financial Reporting
There were no changes in our internal controls during the three months ended June 30, 2019March 31, 2020 that have materially affected or are reasonably likely to have a material effect on our internal control over financial reporting.

Part II — OTHER INFORMATION
Item 1. Legal Proceedings
We are party to several legal proceedings encountered in the ordinary course of business. While the ultimate outcome and impact on us cannot be predicted with certainty, in the opinion of management, it is remote that these legal proceedings will have a material adverse impact on our financial condition, results of operations or cash flows.
On November 4, 2019, the Company received a Notice of Violation and Finding of Violation from the EPA and a Notice of Violation from the New Mexico Environment Department (the “NMED”) alleging violations of the Clean Air Act and New Mexico State Implementation Plan at certain of its operated locations in New Mexico. The Company has provided information to the EPA and NMED and is engaged in discussions regarding a resolution of the alleged violations. The Company believes it is remote that the resolution of this matter will have a material adverse impact on the Company’s financial condition, results of operations or cash flows. Resolution of the matter may result in monetary sanctions of more than $100,000.
Item 1A. Risk Factors
We are subject to various risks and uncertainties in the course of our business. For a discussion of such risks and uncertainties, please see “Item 1A. Risk Factors” in the Annual Report. There have been no material changes to the risk factors we have disclosed in the Annual Report, except as follows:
We Face Numerous Risks Related to the COVID-19 Global Pandemic, Which Has Had and Is Likely to Continue to Have a Material Adverse Effect on Our Business, Financial Condition, Results of Operations and Cash Flows.
Since the beginning of 2020, the COVID-19 pandemic has spread across the globe and disrupted economies and industries around the world, including the exploration and production and midstream businesses. The rapid spread of COVID-19 has led to the implementation of various responses, including federal, state and local government-imposed quarantines, shelter-in-place mandates, sweeping restrictions on travel and other public health and safety measures, nearly all of which have materially reduced global demand for crude oil. The extent to which COVID-19 will continue to affect our business, financial condition, results of operations and cash flows and the demand for our production will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration or any recurrence of the outbreak and responsive measures, additional or modified government actions, new information which may emerge concerning the severity of COVID-19 and the effectiveness of actions taken to contain COVID-19 or treat its impact now or in the future, among others.
Some impacts of the COVID-19 pandemic that could have an adverse effect on our business, financial condition, results of operations and cash flows include:
significantly reduced prices for our oil, natural gas and NGL production, resulting from a world-wide decrease in demand for hydrocarbons and a resulting oversupply of existing production;
further decreases in the demand for our oil production, resulting from significantly decreased levels of global, regional and local travel as a result of federal, state and local government-imposed quarantines, including shelter-in-place mandates, enacted to slow the spread of COVID-19;
increased likelihood that we will, either voluntarily or as a result of third-party and regulatory mandates, curtail or shut in production, resulting from depressed oil prices, lack of storage and other market or political forces;
significant decreases in the volumes of oil, natural gas and water that are transported, gathered, processed or disposed of by San Mateo due to curtailed or shut-in production by Matador or other of San Mateo’s customers; 
increased costs associated with, or actual unavailability of, facilities for the storage of oil, natural gas and NGL production in the markets in which we operate;
increased operational difficulties associated with the delivery of oil, natural gas and NGLs to end-markets, resulting from pipeline and storage constraints;
the potential for the operations of the Black River Processing Plant and other critical midstream infrastructure to be adversely impacted by outbreaks of COVID-19;
the potential for forced curtailment of oil and NGL production by state governmental agencies, resulting in a need to significantly curtail or shut in our production;
the potential for loss of leasehold interests for the failure to produce oil and natural gas in paying quantities as a result of significantly lower commodity prices, voluntary or forced curtailments or other factors related to the misalignment of supply and demand, and the potential to incur significant costs associated with litigation related to the foregoing;

increased third-party credit risk, including the risk that counterparties may not accept the delivery of our oil, natural gas and NGL production, resulting from adverse market conditions, a lack of access to capital and storage and the failure of certain of our counterparties to continue as going concerns;
increased likelihood that counterparties to our existing agreements may seek to invoke force majeure provisions to avoid the performance of contractual obligations, resulting from significantly adverse market conditions;
the potential impact for delays in construction or increased costs related to the expansion of the Black River Processing Plant and other midstream construction projects, including construction of the natural gas pipelines connecting our Stateline asset area and the Greater Stebbins Area to the Black River Processing Plant;
increased costs, staffing requirements and difficulties sourcing oilfield services related to social distancing measures implemented in connection with federal, state or local government and voluntarily imposed quarantines; and
increased legal and operational costs related to compliance with significant changes in federal, state and local laws and regulations.
The COVID-19 outbreak continues to rapidly evolve, and the extent to which the outbreak may impact our business, financial condition, results of operations and cash flows will depend highly on future developments, which are very uncertain and cannot be predicted with confidence. Additionally, the extent and duration of the impact of the COVID-19 pandemic on our stock price and that of our peer companies is uncertain and may make us look less attractive to investors and, as a result, there may be a less active trading market for our common stock, our stock price may be more volatile and our ability to raise capital could be impaired.
