NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1.    Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2019, filed on February 27, 2020 (EOG's 2019 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates. The operating results for the three and six months ended June 30, 2020, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2020, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-13, "Measurement of Credit Losses on Financial Instruments" (ASU 2016-13). ASU 2016-13 changes the impairment model for financial assets and certain other instruments by requiring entities to adopt a forward-looking expected loss model that will result in earlier recognition of credit losses. EOG elected to adopt ASU 2016-13 using the modified retrospective approach with a cumulative-effect adjustment to retained earnings as of the effective date. Financial results reported in periods prior to January 1, 2020, are unchanged. EOG assessed its applicable financial assets, which are primarily its accounts receivable from hydrocarbon sales and joint interest billings to third-party companies, including foreign state-owned entities in the oil and gas industry. Based on its assessment and various potential remedies ensuring collection, EOG did not record an impact to retained earnings upon adoption and expects current and future credit losses to be immaterial. EOG continues to monitor the credit risk from third-party companies to determine if expected credit losses may become material.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12), which amends certain aspects of accounting for income taxes. ASU 2019-12 removes specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020, and early adoption is permitted. EOG is continuing to evaluate the provisions of ASU 2019-12 and has not determined the full impact on its consolidated financial statements and related disclosures.

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2019 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Lease and Well	$	15.1	$	13.6	$	30.2	$	27.3
Gathering and Processing Costs	0.4		0.3		0.6		0.5
Exploration Costs	6.8		6.5		14.0		13.0
General and Administrative	17.3		18.2		34.8		36.9
Total	$	39.6	$	38.6	$	79.6	$	77.7

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

At June 30, 2020, approximately 7.0 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to 2008 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $15.0 million and $13.6 million during the three months ended June 30, 2020 and 2019, respectively, and $29.1 million and $27.5 million during the six months ended June 30, 2020 and 2019, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2020 and 2019 are as follows:

	Stock Options/SARs						ESPP
	Six Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Weighted Average Fair Value of Grants	$	16.94		$	25.68		$	20.80		$	22.98
Expected Volatility	42.10		%	31.50		%	35.24		%	36.31		%
Risk-Free Interest Rate	0.93		%	2.38		%	1.56		%	2.48		%
Dividend Yield	1.94		%	0.96		%	1.56		%	0.83		%
Expected Life	5.1 years			5.1 years			0.5 years			0.5 years

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

At June 30, 2020, unrecognized compensation expense related to restricted stock and restricted stock units totaled $154.2 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.4 years.

Performance Units. EOG grants performance units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the performance units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the performance units granted could be outstanding. The fair value of the performance units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the performance unit grants totaled $1.2 million and $1.9 million for the three months ended June 30, 2020 and 2019, respectively, and $2.3 million and $3.8 million for the six months ended June 30, 2020 and 2019, respectively.

The following table sets forth the performance unit transactions for the six-month periods ended June 30, 2020 and 2019 (units in thousands):

	Six Months Ended June 30, 2020				Six Months Ended June 30, 2019

9.    Pension and Postretirement Benefits

EOG has defined contribution pension plans in place for most of its employees in the United States, and a defined benefit pension plan covering certain of its employees in Trinidad. For the six months ended June 30, 2020 and 2019, EOG's total costs recognized for these pension plans were $20.7 million and $23.0 million, respectively. EOG also has postretirement medical and dental plans in place for eligible employees and their dependents in the United States and Trinidad, the costs of which are not material.

10.    Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at June 30, 2020 and December 31, 2019, and did not utilize any commercial paper borrowings during the six months ended June 30, 2020 and 2019.

At June 30, 2020, $750 million aggregate principal amount of EOG's 4.100% Senior Notes due 2021 was reclassified as long-term debt as a result of EOG's intent and ability to ultimately replace such amounts with other long-term debt.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-total capitalization (as such terms are defined in the Agreement) of no greater than 65%. At June 30, 2020, EOG was in compliance with this financial covenant. At June 30, 2020 and December 31, 2019, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at June 30, 2020, would have been 1.06% and 3.25%, respectively.

On April 1, 2020, EOG repaid upon maturity the $500 million aggregate principal amount of its 2.45% Senior Notes due 2020.

On April 14, 2020, EOG closed on its offering of $750 million aggregate principal amount of its 4.375% Senior Notes due 2030 and $750 million aggregate principal amount of its 4.950% Senior Notes due 2050 (together, the Notes). Interest on the Notes is payable semi-annually in arrears on April 15 and October 15 of each year, beginning on October 15, 2020. EOG received net proceeds of approximately $1.48 billion from the issuance of the Notes, which were used to repay the 4.40% Senior Notes due 2020 when they matured on June 1, 2020 (see below), and have also been used (and will continue to be used) for general corporate purposes, including the funding of capital expenditures.

On June 1, 2020, EOG repaid upon maturity the $500 million aggregate principal amount of its 4.40% Senior Notes due 2020.

Common Stock. On February 27, 2020, EOG's Board of Directors increased the quarterly cash dividend on the common stock from the previous $0.2875 per share to $0.375 per share, effective beginning with the dividend paid on April 30, 2020, to stockholders of record as of April 16, 2020.

(1) $207 million and $1 million are included in "Current Assets - Assets from Price Risk Management Activities" at June 30, 2020 and December 31, 2019, respectively, on the Condensed Consolidated Balance Sheets. $2 million is included in "Other Assets" at June 30, 2020, on the Condensed Consolidated Balance Sheets.

(2) $20 million is included in "Current Liabilities - Liabilities from Price Risk Management Activities" at December 31, 2019, on the Condensed Consolidated Balance Sheets.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) future crude oil and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the ASC. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

During the first half of 2020, due to the decline in commodity prices, proved oil and gas properties with a carrying amount of $1,424 million were written down to their fair value of $264 million, resulting in pretax impairment charges of $1,160 million for the six months ended June 30, 2020. In addition, EOG recorded pretax impairment charges of $72 million for the six months ended June 30, 2020, for a commodity price-related write-down of other assets.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At June 30, 2020 and December 31, 2019, respectively, EOG had outstanding $5,640 million and $5,140 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $6,416 million and $5,452 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

12.    Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2019 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Crude Oil Derivative Contracts. Prices received by EOG for its crude oil production generally vary from U.S. New York Mercantile Exchange (NYMEX) West Texas Intermediate (WTI) prices due to adjustments for delivery location (basis) and other factors. EOG has entered into crude oil basis swap contracts in order to fix the differential between Intercontinental Exchange (ICE) Brent pricing and pricing in Cushing, Oklahoma (ICE Brent Differential). Presented below is a comprehensive summary of EOG's ICE Brent Differential basis swap contracts as of June 30, 2020. The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of addition to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

EOG has entered into natural gas collar contracts, which establish ceiling and floor prices for the sale of notional volumes of natural gas as specified in the collar contracts. The collars require that EOG pay the difference between the ceiling price and the NYMEX Henry Hub natural gas price for the contract month (Henry Hub Index Price) in the event the Henry Hub Index Price is above the ceiling price. The collars grant EOG the right to receive the difference between the floor price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the floor price. In March 2020, EOG executed the early termination provision granting EOG the right to terminate certain 2020 natural gas collar contracts with notional volumes of 250,000 MMBtud at a weighted average ceiling price of $2.50 per MMBtu and a weighted average floor price of $2.00 per MMBtu for the period from April 1, 2020 through July 31, 2020.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net asset position at June 30, 2020 and December 31, 2019. EOG had no collateral posted and held collateral of $62 million at June 30, 2020, and had no collateral posted and held no collateral at December 31, 2019.

PART I.  FINANCIAL INFORMATION

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

EOG RESOURCES, INC.

Overview

EOG Resources, Inc., together with its subsidiaries (collectively, EOG), is one of the largest independent (non-integrated) crude oil and natural gas companies in the United States with proved reserves in the United States, Trinidad and China. EOG operates under a consistent business and operational strategy that focuses predominantly on maximizing the rate of return on investment of capital by controlling operating and capital costs and maximizing reserve recoveries. Each prospective drilling location is evaluated by its estimated rate of return. This strategy is intended to enhance the generation of cash flow and earnings from each unit of production on a cost-effective basis, allowing EOG to deliver long-term production growth while maintaining a strong balance sheet. EOG implements its strategy primarily by emphasizing the drilling of internally generated prospects in order to find and develop low-cost reserves. Maintaining the lowest possible operating cost structure that is consistent with efficient, safe and environmentally responsible operations is also an important goal in the implementation of EOG's strategy.

Recent Developments. The COVID-19 pandemic and the measures being taken to address and limit the spread of the virus have adversely affected the economies and financial markets of the world, resulting in an economic downturn that has negatively impacted, and may continue to negatively impact, global demand and prices for crude oil and condensate, natural gas liquids (NGLs) and natural gas. See PART II, ITEM 1A, "Risk Factors" below, for further discussion.

In early March 2020, due to the failure of the members of the Organization of the Petroleum Exporting Countries and Russia (OPEC+) to reach an agreement on individual crude oil production limits, Saudi Arabia unilaterally reduced the sales price of its crude oil and announced that it would increase its crude oil production. The combination of these actions and the effects of the COVID-19 pandemic on crude oil demand, resulted in lower commodity prices in March and April 2020. In April 2020, the members of OPEC+ reached an agreement to cut production beginning in May 2020 and extending through April 2022 with the quantity of the production cuts decreasing over time. In May and June 2020, crude oil prices recovered, but remain significantly below average prices in 2019 as a result of the rebalancing of crude oil supply from the actions of OPEC+ and the continuing effect of the COVID-19 pandemic on global demand.

In response to the current commodity price environment, EOG updated its 2020 capital and operating plan to reduce activity across its operating areas and decrease its total anticipated 2020 capital expenditures. EOG also elected to reduce its 2020 crude oil production, including delaying initial production from new wells and shutting-in or otherwise curtailing existing production. As a result, EOG expects its full-year 2020 total crude oil production to be lower than its full-year 2019 total crude oil production. See "2020 Capital and Operating Plan" below for further discussion.

Commodity Prices. As a result of the many uncertainties associated with (i) the world economic environment, (ii) the COVID-19 pandemic and its continuing effect on the economies and financial markets of the world and (iii) any future actions by the members of OPEC+, and the effect of these uncertainties on worldwide supplies of, and demand for, crude oil and condensate, NGLs and natural gas, EOG is unable to predict what changes may occur in crude oil and condensate, NGLs, and natural gas prices in the future. However, prices for crude oil and condensate, NGLs and natural gas have historically been volatile, and this volatility is expected to continue.

The market prices of crude oil and condensate, NGLs and natural gas during the remainder of 2020 will impact the amount of cash generated from EOG's operating activities, which will in turn impact EOG's financial position and results of operations. For the first six months of 2020, the average U.S. New York Mercantile Exchange (NYMEX) crude oil and condensate and natural gas prices were $36.97 per barrel and $1.85 per million British thermal units (MMBtu), respectively, both representing decreases of 36% from the average NYMEX prices for the same period in 2019. Market prices for NGLs are influenced by the components extracted, including ethane, propane and butane and natural gasoline, among others, and the respective market pricing for each component.

United States. EOG's efforts to identify plays with large reserve potential have proven to be successful. EOG has placed an emphasis on applying its horizontal drilling and completion expertise to unconventional crude oil and liquids-rich reservoirs, EOG continues to drill numerous wells in large acreage plays, which in the aggregate have contributed substantially to, and are expected to continue to contribute substantially to, EOG's crude oil and liquids-rich natural gas production.

During the first six months of 2020, EOG continued to focus on increasing drilling, completion and operating efficiencies gained in prior years. In addition, EOG continued to evaluate certain potential crude oil and liquids-rich natural gas exploration and development prospects and to look for opportunities to add drilling inventory through leasehold acquisitions, farm-ins, exchanges or tactical acquisitions. On a volumetric basis, as calculated using the ratio of 1.0 barrel of crude oil and condensate or NGLs to 6.0 thousand cubic feet of natural gas, crude oil and condensate and NGL production accounted for approximately 76% and 77% of EOG's United States production during the first six months of  2020 and 2019, respectively. During the first six months of 2020, EOG's drilling and completion activities occurred primarily in the Eagle Ford play, Delaware Basin play and Rocky Mountain area. EOG's major producing areas in the United States are in New Mexico and Texas. In the second quarter of 2020, EOG delayed initial production from most newly-completed wells and shut in some existing production.

Trinidad. In Trinidad, EOG continues to deliver natural gas under existing supply contracts. Several fields in the South East Coast Consortium (SECC) Block, Modified U(a) Block, Block 4(a), Modified U(b) Block, the Banyan Field and the Sercan Area have been developed and are producing natural gas which is sold to the National Gas Company of Trinidad and Tobago Limited and its subsidiary, and crude oil and condensate which is sold to Heritage Petroleum Company Limited. In the first half of 2020, EOG completed the drilling of one net exploratory well and was in the process of drilling and completing a second well on a different block as of June 30, 2020. Subsequent to the second quarter of 2020, it was announced that one of the exploratory wells found commercial quantities of proved reserves. During the remainder of 2020, EOG plans to drill two additional net wells, continue its evaluation of the remaining exploratory well and begin formulating development plans.

Other International. In the Sichuan Basin, Sichuan Province, China, EOG continues to work closely with its partner, PetroChina, under the Production Sharing Contract and other related agreements, to ensure uninterrupted production in order to reach the level allowed by pipeline capacity. All natural gas produced from the Baijaochang Field is sold under a long-term contract to PetroChina.

In March 2020, EOG began the process of exiting its Canada operations.

EOG continues to evaluate other select crude oil and natural gas opportunities outside the United States, primarily by pursuing exploitation opportunities in countries where indigenous crude oil and natural gas reserves have been identified.

Management continues to believe EOG has one of the strongest prospect inventories in EOG's history. When it fits EOG's strategy, EOG will make acquisitions that bolster existing drilling programs or offer incremental exploration and/or production opportunities.

2020 Capital and Operating Plan. Total anticipated 2020 capital expenditures are estimated to range from approximately $3.4 billion to $3.6 billion, including facilities and gathering, processing and other expenditures, and excluding acquisitions and non-cash transactions. The updated 2020 capital and operating plan represents a reduction in total anticipated capital expenditures compared to the original 2020 capital and operating plan and, as a result, EOG expects its full-year 2020 total crude oil production to be lower than its full-year 2019 total crude oil production.

EOG's 2020 capital expenditures will continue to be focused on drilling operations in its high rate-of-return plays as well as targeted infrastructure, exploration and environmental projects that support the long-term value of EOG. EOG remains flexible and will continue to evaluate its 2020 capital and operating plan. EOG expects to continue monitoring market conditions in the second half of the year and adjust its production volumes accordingly, with the anticipation of increasing production as prices improve. EOG will also continue to exercise financial flexibility with a goal toward preserving liquidity while supporting its dividend.

Capital Structure. One of management's key strategies is to maintain a strong balance sheet with a consistently below average debt-to-total capitalization ratio as compared to those in EOG's peer group. EOG's debt-to-total capitalization ratio was 22% at June 30, 2020 and 19% at December 31, 2019. As used in this calculation, total capitalization represents the sum of total current and long-term debt and total stockholders' equity.

-24-

At June 30, 2020, EOG maintained a strong financial and liquidity position, including $2.4 billion of cash and cash equivalents and $2.0 billion of availability under its senior unsecured revolving credit facility. EOG's cash and cash equivalents as of June 30, 2020 included $62 million of collateral deposits from counterparties in anticipation of future settlements of financial commodity derivative contracts.

On April 1, 2020, EOG repaid, with cash on hand, the $500 million aggregate principal amount of its 2.45% Senior Notes due 2020 that matured on that date.

On April 14, 2020, EOG closed on its offering of $750 million aggregate principal amount of its 4.375% Senior Notes due 2030 and $750 million aggregate principal amount of its 4.950% Senior Notes due 2050 (together, the Notes). EOG received net proceeds of approximately $1.48 billion from the issuance of the Notes, which were used to repay the 4.40% Senior Notes due 2020 when they matured on June 1, 2020 (see below), and have also been used (and will continue to be used) for general corporate purposes, including the funding of capital expenditures.

Additionally, on June 1, 2020, EOG repaid, with cash on hand, the $500 million aggregate principal amount of its 4.40% Senior Notes due 2020 that matured on that date.

EOG believes it has significant flexibility and availability with respect to financing alternatives, including borrowings under its commercial paper program, bank borrowings, borrowings under its senior unsecured revolving credit facility, joint development agreements and similar agreements and equity and debt offerings.

        Wellhead crude oil and condensate revenues for the second quarter of 2020 decreased $1,914 million, or 76%, to $615 million from $2,529 million for the same period of 2019. The decrease was due to a lower composite average price ($1,223 million) and a decrease of 125 MBbld, or 27%, in wellhead crude oil and condensate production ($691 million). Decreased production was primarily in the Eagle Ford, the Rocky Mountain area and the Permian Basin. EOG's composite wellhead crude oil and condensate price for the second quarter of 2020 decreased 67% to $20.40 per barrel compared to $60.99 per barrel for the same period of 2019.

        NGL revenues for the second quarter of 2020 decreased $92 million, or 50%, to $94 million from $186 million for the same period of 2019 due to a lower composite average price ($50 million) and a decrease of 30 MBbld, or 23%, in NGL deliveries ($42 million). Decreased production was primarily in the Eagle Ford, the Permian Basin and the Rocky Mountain area. EOG's composite NGL price for the second quarter of 2020 decreased 35% to $10.20 per barrel compared to $15.63 per barrel for the same period of 2019.

        Wellhead natural gas revenues for the second quarter of 2020 decreased $128 million, or 47%, to $142 million from $270 million for the same period of 2019. The decrease was due to a lower average composite price ($86 million) and a decrease in natural gas deliveries ($42 million). Natural gas deliveries for the second quarter of 2020 decreased 209 MMcfd, or 15%, compared to the same period of 2019 due primarily to lower natural gas volumes in Trinidad, the Rocky Mountain area and the Marcellus Shale. EOG's composite wellhead natural gas price for the second quarter of 2020 decreased 38% to $1.36 per Mcf compared to $2.19 per Mcf for the same period of 2019.

        During the second quarter of 2020, EOG recognized net losses on the mark-to-market of financial commodity derivative contracts of $126 million compared to net gains of $177 million for the same period of 2019. During the second quarter of 2020, net cash received from settlements of financial commodity derivative contracts was $639 million compared to net cash received of $10 million for the same period of 2019.

        Gathering, processing and marketing revenues are revenues generated from sales of third-party crude oil, NGLs and natural gas, as well as fees associated with gathering third-party natural gas and revenues from sales of EOG-owned sand. Purchases and sales of third-party crude oil and natural gas may be utilized in order to balance firm transportation capacity with production in certain areas and to utilize excess capacity at EOG-owned facilities. EOG sells sand in order to balance the timing of firm purchase agreements with completion operations and to utilize excess capacity at EOG-owned facilities. Marketing costs represent the costs to purchase third-party crude oil, natural gas and sand and the associated transportation costs, as well as costs associated with EOG-owned sand sold to third parties.

        Gathering, processing and marketing revenues less marketing costs for the second quarter of 2020 decreased $82 million as compared to the same period of 2019 primarily due to lower margins on crude oil marketing activities. The margin on crude oil marketing activities for the second quarter of 2020 was negatively impacted by the decision early in the second quarter of 2020 to reduce commodity price volatility by selling May and June 2020 deliveries under fixed price arrangements.

Operating and Other Expenses.  For the second quarter of 2020, operating expenses of $2,190 million were $1,377 million lower than the $3,567 million incurred during the second quarter of 2019.  The following table presents the costs per barrel of oil equivalent (Boe) for the three-month periods ended June 30, 2020 and 2019:

	Three Months Ended June 30,
	2020		2019
Lease and Well	$	4.32	$	4.70
Transportation Costs	2.67		2.35
Depreciation, Depletion and Amortization (DD&A) -
Oil and Gas Properties	11.84		12.55
Other Property, Plant and Equipment	0.62		0.39
General and Administrative (G&A)	2.32		1.65
Interest Expense, Net	0.96		0.67
Total (1)	$	22.73	$	22.31

(1)Total excludes gathering and processing costs, exploration costs, dry hole costs, impairments, marketing costs and taxes other than income.

The primary factors impacting the cost components of per-unit rates of lease and well, transportation, DD&A, G&A and net interest expense for the three months ended June 30, 2020, compared to the same period of 2019, are set forth below. See "Operating Revenues" above for a discussion of wellhead volumes.

Lease and well expenses include expenses for EOG-operated properties, as well as expenses billed to EOG from other operators where EOG is not the operator of a property. Lease and well expenses can be divided into the following categories: costs to operate and maintain crude oil and natural gas wells, the cost of workovers and lease and well administrative expenses. Operating and maintenance costs include, among other things, pumping services, salt water disposal, equipment repair and maintenance, compression expense, lease upkeep and fuel and power. Workovers are operations to restore or maintain production from existing wells.

        Each of these categories of costs individually fluctuates from time to time as EOG attempts to maintain and increase production while maintaining efficient, safe and environmentally responsible operations. EOG continues to increase its operating activities by drilling new wells in existing and new areas. Operating and maintenance costs within these existing and new areas, as well as the costs of services charged to EOG by vendors, fluctuate over time.

        Lease and well expenses of $245 million for the second quarter of 2020 decreased $102 million from $347 million for the same prior year period primarily due to decreased operating and maintenance costs ($50 million) and decreased workover expenditures ($44 million), both in the United States, and decreased operating and maintenance costs in Canada ($8 million).

        Transportation costs represent costs associated with the delivery of hydrocarbon products from the lease to a downstream point of sale. Transportation costs include transportation fees, the cost of compression (the cost of compressing natural gas to meet pipeline pressure requirements), the cost of dehydration (the cost associated with removing water from natural gas to meet pipeline requirements), gathering fees and fuel costs.

        Transportation costs of $152 million for the second quarter of 2020 decreased $22 million from $174 million for the same prior year period primarily due to decreased transportation costs in the Rocky Mountain area ($14 million), Eagle Ford ($10 million) and Barnett Shale ($7 million), partially offset by increased transportation costs in the Permian Basin ($8 million) and South Texas ($3 million).

        DD&A of the cost of proved oil and gas properties is calculated using the unit-of-production method. EOG's DD&A rate and expense are the composite of numerous individual DD&A group calculations. There are several factors that can impact EOG's composite DD&A rate and expense, such as field production profiles, drilling or acquisition of new wells, disposition of existing wells and reserve revisions (upward or downward) primarily related to well performance, economic factors and impairments. Changes to these factors may cause EOG's composite DD&A rate and expense to fluctuate from period to period. DD&A of the cost of other property, plant and equipment is generally calculated using the straight-line depreciation method over the useful lives of the assets.

DD&A expenses for the second quarter of 2020 decreased $250 million to $707 million from $957 million for the same prior year period. DD&A expenses associated with oil and gas properties for the second quarter of 2020 were $256 million lower than the same prior year period. The decrease primarily reflects decreased production in the United States ($202 million) and in Trinidad ($8 million) and lower unit rates in the United States ($47 million). Unit rates in the United States decreased primarily due to upward reserve revisions and reserves added at lower costs as a result of increased efficiencies. DD&A expenses associated with other property, plant and equipment for the second quarter of 2020 were $6 million higher than the same prior year period primarily due to an increase in expense related to gathering and storage assets and equipment.

G&A expenses of $132 million for the second quarter of 2020 increased $10 million from $122 million for the same prior year period primarily due to idle equipment and termination fees ($26 million) and increased information system costs ($2 million), partially offset by a decrease in professional and other services ($11 million) and employee-related costs ($5 million).

Exploration costs of $27 million for the second quarter of 2020 decreased $5 million from $33 million for the same prior year period primarily due to decreased geological and geophysical costs in the United States.

Interest expense, net of $54 million for the second quarter of 2020 increased $4 million compared to the same prior year period primarily due to the issuance of the Notes in April 2020 ($15 million), partially offset by repayment in June 2019 of the $900 million aggregate principal amount of 5.625% Senior Notes due 2019 ($9 million).

Gathering and processing costs represent operating and maintenance expenses and administrative expenses associated with operating EOG's gathering and processing assets as well as natural gas processing fees and certain NGL fractionation fees paid to third parties. EOG pays third parties to process the majority of its natural gas production to extract NGLs.

Gathering and processing costs decreased $16 million to $97 million for the second quarter of 2020 compared to $113 million for the same prior year period primarily due to decreased operating costs ($8 million) and decreased gathering and processing fees ($6 million), both in the Eagle Ford.

Impairments include: amortization of unproved oil and gas property costs as well as impairments of proved oil and gas properties; other property, plant and equipment; and other assets. Unproved properties with acquisition costs that are not individually significant are aggregated, and the portion of such costs estimated to be nonproductive is amortized over the remaining lease term. Unproved properties with individually significant acquisition costs are reviewed individually for impairment. When circumstances indicate that a proved property may be impaired, EOG compares expected undiscounted future cash flows at a DD&A group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimates of (and assumptions regarding) future crude oil and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated by using the Income Approach described in the Fair Value Measurement Topic of the Financial Accounting Standards Board's Accounting Standards Codification. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

Impairments of $305 million for the second quarter of 2020 were $193 million higher than impairments for the same prior year period primarily due to the impairments of sand and crude-by-rail assets in the United States ($219 million), of proved properties as a result of the decision to exit the Horn River Basin in Canada ($19 million) and increased amortization of unproved property costs in the United States ($14 million), partially offset by lower impairments of other assets in the United States ($60 million). EOG recorded impairments of proved properties, other property, plant and equipment and other assets of $245 million and $65 million for the second quarters of 2020 and 2019, respectively.

-30-

Taxes other than income include severance/production taxes, ad valorem/property taxes, payroll taxes, franchise taxes and other miscellaneous taxes. Severance/production taxes are generally determined based on wellhead revenues, and ad valorem/property taxes are generally determined based on the valuation of the underlying assets.

Taxes other than income for the second quarter of 2020 decreased $124 million to $80 million (9.4% of wellhead revenues) from $204 million (6.8% of wellhead revenues) for the same prior year period. The decrease in taxes other than income was primarily due to decreased severance/production taxes ($119 million) and decreased ad valorem/property taxes ($8 million), partially offset by a decrease in credits available to EOG in the second quarter of 2020 for state incentive severance tax rate reductions ($4 million), all in the United States.

Other income (expense), net for the second quarter of 2020 decreased $13 million compared to the same prior year period primarily due to an increase in deferred compensation expense ($7 million) and decrease in interest income ($5 million).

        In response to the economic impacts of the COVID-19 pandemic, the President of the United States signed the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) into law on March 27, 2020. The CARES Act provides economic support to individuals and businesses through enhanced loan programs, expanded unemployment benefits, and certain payroll and income tax relief, among other provisions.  The primary tax benefit of the CARES Act for EOG was the acceleration of approximately $150 million of additional refundable alternative minimum tax (AMT) credits into tax year 2019.  These credits originated from AMT paid by EOG in years prior to 2018 and were reflected as a deferred tax asset and a non-current receivable as of December 31, 2019 since they had been expected to either offset future current tax liabilities or be refunded on a declining balance schedule through 2021. As a result of the CARES Act, EOG has reclassified these credits from a non-current receivable in Other Assets to a current receivable in Income Taxes Receivable on the Condensed Consolidated Balance Sheet at June 30, 2020. The $150 million of additional refundable AMT credits were received in July 2020.

        EOG recognized an income tax benefit of $236 million for the second quarter of 2020 compared to an income tax provision of $242 million for the second quarter of 2019, primarily due to decreased pretax income.  The net effective tax rate for the second quarter of 2020 decreased to 21% from 22% in 2019.

Six Months Ended June 30, 2020 vs. Six Months Ended June 30, 2019

        Operating Revenues. During the first six months of 2020, operating revenues decreased $2,935 million, or 34%, to $5,821 million from $8,756 million for the same period of 2019. Total wellhead revenues for the first six months of 2020 decreased $2,453 million, or 43%, to $3,286 million from $5,739 million for the same period of 2019. During the first six months of 2020, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $1,079 million compared to net gains of $157 million for the same period of 2019. Gathering, processing and marketing revenues for the first six months of 2020 decreased $1,386 million, or 50%, to $1,401 million from $2,787 million for the same period of 2019. Net gains on asset dispositions were $30 million for the first six months of 2020 compared to net gains of $4 million for the same period of 2019.

        Wellhead crude oil and condensate revenues for the first six months of 2020 decreased $2,049 million, or 43%, to $2,680 million from $4,729 million for the same period of 2019 due to a lower composite average price ($1,663 million) and a decrease of 39 MBbld, or 9%, in wellhead crude oil and condensate production ($386 million). Decreased production was primarily due to decreases in the Eagle Ford and the Rocky Mountain area, partially offset by increased production in the Permian Basin. EOG's composite wellhead crude oil and condensate price for the first six months of 2020 decreased 38% to $36.16 per barrel compared to $58.61 per barrel for the same period of 2019.

        NGL revenues for the first six months of 2020 decreased $151 million, or 37%, to $254 million from $405 million for the same period of 2019 due to a lower composite average price ($172 million), partially offset by an increase of 6 MBbld, or 5%, in NGL deliveries ($21 million). Increased production was primarily in the Permian Basin. EOG's composite NGL price for the first six months of 2020 decreased 40% to $10.65 per barrel compared to $17.84 per barrel for the same period of 2019.

        Wellhead natural gas revenues for the first six months of 2020 decreased $254 million, or 42%, to $351 million from $605 million for the same period of 2019. The decrease was due to a lower composite wellhead natural gas price ($225 million) and a decrease in natural gas deliveries ($29 million). Natural gas deliveries for the first six months of 2020 decreased 70 MMcfd, or 5%, compared to the same period of 2019 due primarily to lower natural gas volumes in Trinidad, the Rocky Mountain area and the Marcellus Shale, partially offset by higher deliveries in South Texas and increased production of associated natural gas from the Permian Basin. EOG's composite wellhead natural gas price for the first six months of 2020 decreased 39% to $1.53 per Mcf compared to $2.51 per Mcf for the same period of 2019.

        During the first six months of 2020, EOG recognized net gains on the mark-to-market of financial commodity derivative contracts of $1,079 million compared to net gains of $157 million for the same period of 2019. During the first six months of 2020, net cash received from settlements of financial commodity derivative contracts was $724 million compared to net cash received for settlements of financial commodity derivative contracts of $31 million for the same period of 2019.

        Gathering, processing and marketing revenues less marketing costs for the first six months of 2020 decreased $168 million as compared to the same period of 2019 primarily due to lower margins on crude oil marketing activities, partially offset by higher margins on natural gas marketing activities. The margin on crude oil marketing activities for the first six months of 2020 was negatively impacted by the decline in price on crude oil in inventory awaiting delivery to customers and the decision early in the second quarter of 2020 to reduce commodity price volatility by selling May and June 2020 deliveries under fixed price arrangements.

Operating and Other Expenses. For the first six months of 2020, operating expenses of $6,850 million were $101 million higher than the $6,749 million incurred during the same period of 2019. The following table presents the costs per Boe for the six-month periods ended June 30, 2020 and 2019:

	Six Months Ended June 30,

        The primary factors impacting the cost components of per-unit rates of lease and well, transportation, DD&A, G&A and net interest expense for the six months ended June 30, 2020, compared to the same period of 2019 are set forth below. See "Operating Revenues" above for a discussion of wellhead volumes.

-33-

        Lease and well expenses of $575 million for the first six months of 2020 decreased $109 million from $684 million for the same prior year period primarily due to decreased workover expenditures ($54 million) and decreased operating and maintenance costs ($50 million), both in the United States, and decreased operating and maintenance costs in Canada ($14 million), partially offset by increased lease and well administrative expenses in the United States ($13 million).

        Transportation costs of $360 million for the first six months of 2020 increased $9 million from $351 million for the same prior year period primarily due to increased transportation costs in the Permian Basin ($43 million) and South Texas ($8 million), partially offset by decreased transportation costs in the Barnett Shale ($17 million), Rocky Mountain area ($10 million), Eagle Ford ($10 million) and Marcellus Shale ($2 million).

DD&A expenses for the first six months of 2020 decreased $130 million to $1,707 million from $1,837 million for the same prior year period. DD&A expenses associated with oil and gas properties for the first six months of 2020 were $141 million lower than the same prior year period. The decrease primarily reflects lower unit rates in the United States ($71 million) and decreased production in the United States ($61 million) and in Trinidad ($12 million). Unit rates in the United States decreased primarily due to upward reserve revisions and reserves added at lower costs as a result of increased efficiencies. DD&A expenses associated with other property, plant and equipment for the first six months of 2020 were $11 million higher than the same prior year period primarily due to an increase in expense related to gathering and storage assets and equipment.

        G&A expenses of $246 million for the first six months of 2020 increased $18 million from $228 million for the same prior year period primarily due to idle equipment and termination fees ($26 million) and increased information system costs ($5 million), partially offset by a decrease in professional and other services ($8 million) and employee-related costs ($7 million).

        Interest expense, net of $99 million for the first six months of 2020 decreased $6 million compared to the same prior year period primarily due to repayment in June 2019 of the $900 million aggregate principal amount of 5.625% Senior Notes due 2019 ($21 million), partially offset by the issuance of the Notes in April 2020 ($15 million).

Impairments of $1,878 million for the first six months of 2020 were $1,694 million higher than impairments for the same prior year period primarily due to increased impairments of proved properties and other assets, primarily related to legacy and non-core natural gas, crude oil and combo plays in the United States ($1,374 million), sand and crude-by-rail assets in the United States ($219 million), as a result of the decision to exit the Horn River Basin in Canada ($79 million) and increased amortization of unproved property costs in the United States ($23 million). EOG recorded impairments of proved properties, other property, plant and equipment and other assets of $1,761 million and $91 million for the first six months of 2020 and 2019, respectively.

Taxes other than income for the first six months of 2020 decreased $159 million to $238 million (7.2% of wellhead revenues) from $397 million (6.9% of wellhead revenues) for the same prior year period. The decrease in taxes other than income was primarily due to decreased severance/production taxes ($128 million), decreased ad valorem/property taxes ($27 million) and an increase in credits available to EOG in the first six months of 2020 for state incentive severance tax rate reductions ($5 million), all in the United States.

EOG recognized an income tax benefit of $215 million for the first six months of 2020 compared to an income tax provision of $433 million for the first six months of 2019, primarily due to decreased pretax income. The net effective tax rate for the first six months of 2020 decreased to 19% from 23% in the first six months of 2019. The lower effective tax rate is mostly due to EOG's foreign operations, primarily related to increased losses in Canada, which have not been tax effected due to valuation allowances.

Capital Resources and Liquidity

        Cash Flow. The primary sources of cash for EOG during the six months ended June 30, 2020, were funds generated from operations, net proceeds from the issuance of long-term debt and net cash received from settlements of commodity derivative contracts. The primary uses of cash were exploration and development expenditures; funds used in operations; long-term debt repayments; dividend payments to stockholders; and other property, plant and equipment expenditures. During the first six months of 2020, EOG's cash balance increased $389 million to $2,417 million from $2,028 million at December 31, 2019.

        Net cash provided by operating activities of $2,673 million for the first six months of 2020 decreased $1,621 million compared to the same period of 2019 primarily due to a decrease in wellhead revenues ($2,453 million), a decrease in net cash received relating to income taxes ($255 million) and a decrease in gathering, processing and marketing revenues less marketing costs ($168 million), partially offset by an increase in net cash received for settlements of commodity derivative contracts ($692 million), a decrease in cash operating expenses ($239 million) and a favorable change in working capital ($95 million).

        Net cash used in investing activities of $2,376 million for the first six months of 2020 decreased by $1,147 million compared to the same period of 2019 due to a decrease in additions to oil and gas properties ($1,456 million) and an increase in proceeds from the sale of assets ($26 million), partially offset by an unfavorable change in components of working capital associated with investing activities ($304 million) and an increase in additions to other property, plant and equipment ($30 million).

        Net cash provided by financing activities of $92 million for the first six months of 2020 included net proceeds from the issuance of long-term debt ($1,484 million). Net cash used in financing activities for the first six months of 2020 included repayments of long-term debt ($1,000 million) and cash dividend payments ($384 million).

Total Expenditures. For the year 2020, EOG's updated budget for exploration and development and other property, plant and equipment expenditures is estimated to range from approximately $3.4 billion to $3.6 billion, excluding acquisitions and non-cash transactions. The table below sets out components of total expenditures for the six-month periods ended June 30, 2020 and 2019 (in millions):

	Six Months Ended June 30,
	2020		2019
Expenditure Category
Capital
Exploration and Development Drilling	$	1,694	$	2,692
Facilities	210		338
Leasehold Acquisitions (1)	75		145
Property Acquisitions (2)	51		322
Capitalized Interest	17		18
Subtotal	2,047		3,515
Exploration Costs	67		69
Dry Hole Costs	—		4
Exploration and Development Expenditures	2,114		3,588
Asset Retirement Costs	25		60
Total Exploration and Development Expenditures	2,139		3,648
Other Property, Plant and Equipment (3)	221		117
Total Expenditures	$	2,360	$	3,765

(1) Leasehold acquisitions included $48 million and $54 million for the six-month periods ended June 30, 2020 and 2019, respectively, related to non-cash property exchanges.

(2) Property acquisitions included $7 million and $18 million for the six-month periods ended June 30, 2020 and 2019, respectively, related to non-cash property exchanges.

(3) Other property, plant and equipment included $73 million of non-cash additions for the six-month period ended June 30, 2020 made in connection with a finance lease transaction.

        Exploration and development expenditures of $2,114 million for the first six months of 2020 were $1,474 million lower than the same period of 2019 primarily due to decreased exploration and development drilling expenditures in the United States ($1,021 million) and Other International ($9 million), decreased property acquisitions ($271 million), decreased facilities expenditures ($128 million) and decreased leasehold acquisitions ($70 million), partially offset by increased exploration and development drilling expenditures in Trinidad ($31 million). Exploration and development expenditures for the first six months of 2020 of $2,114 million consisted of $1,840 million in development drilling and facilities, $206 million in exploration, $51 million in property acquisitions and $17 million in capitalized interest. Exploration and development expenditures for the first six months of 2019 of $3,588 million consisted of $3,010 million in development drilling and facilities, $322 million in property acquisitions, $238 million in exploration and $18 million in capitalized interest.

The level of exploration and development expenditures, including acquisitions, will vary in future periods depending on energy market conditions and other economic factors. EOG believes it has significant flexibility and availability with respect to financing alternatives and the ability to adjust its exploration and development expenditure budget as circumstances warrant. While EOG has certain continuing commitments associated with expenditure plans related to its operations, such commitments are not expected to be material when considered in relation to the total financial capacity of EOG.

Commodity Derivative Transactions. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's Annual Report on Form 10-K for the year ended December 31, 2019, filed on February 27, 2020, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method. Under this accounting method, changes in the fair value of outstanding financial instruments are recognized as gains or losses in the period of change and are recorded as Gains (Losses) on Mark-to-Market Commodity Derivative Contracts on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss). The related cash flow impact is reflected in Cash Flows from Operating Activities on the Condensed Consolidated Statements of Cash Flows.

The total fair value of EOG's commodity derivative contracts was reflected on the Condensed Consolidated Balance Sheets at June 30, 2020, as a net asset of $209 million.

        Crude Oil Derivative Contracts. Prices received by EOG for its crude oil production generally vary from NYMEX West Texas Intermediate (WTI) prices due to adjustments for delivery location (basis) and other factors. EOG has entered into crude oil basis swap contracts in order to fix the differential between Intercontinental Exchange (ICE) Brent pricing and pricing in Cushing, Oklahoma (ICE Brent Differential). Presented below is a comprehensive summary of EOG's ICE Brent Differential basis swap contracts through July 30, 2020. The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of addition to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

        EOG has entered into natural gas collar contracts, which establish ceiling and floor prices for the sale of notional volumes of natural gas as specified in the collar contracts. The collars require that EOG pay the difference between the ceiling price and the NYMEX Henry Hub natural gas price for the contract month (Henry Hub Index Price) in the event the Henry Hub Index Price is above the ceiling price. The collars grant EOG the right to receive the difference between the floor price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the floor price. In March 2020, EOG executed the early termination provision granting EOG the right to terminate certain 2020 natural gas collar contracts with notional volumes of 250,000 MMBtud at a weighted average ceiling price of $2.50 per MMBtu and a weighted average floor price of $2.00 per MMBtu for the period from April 1, 2020 through July 31, 2020. The net cash EOG received for settling these contracts was $7.8 million. Presented below is a comprehensive summary of EOG's natural gas collar contracts through July 30, 2020, with notional volumes expressed in MMBtud and prices expressed in $/MMBtu.

•the use of competing energy sources and the development of alternative energy sources;

•the extent to which EOG incurs uninsured losses and liabilities or losses and liabilities in excess of its insurance coverage;

•acts of war and terrorism and responses to these acts; and

•the other factors described under ITEM 1A, Risk Factors, on pages 13 through 23 of EOG's Annual Report on Form 10-K for the fiscal year ended December 31, 2019, under ITEM 1A, Risk Factors, on page 37 of EOG's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2020, and under ITEM 1A, Risk Factors, in this Quarterly Report on Form 10-Q, and any updates to those factors set forth in EOG's subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K.

        In light of these risks, uncertainties and assumptions, the events anticipated by EOG's forward-looking statements may not occur, and, if any of such events do, we may not have anticipated the timing of their occurrence or the duration or extent of their impact on our actual results. Accordingly, you should not place any undue reliance on any of EOG's forward-looking statements. EOG's forward-looking statements speak only as of the date made, and EOG undertakes no obligation, other than as required by applicable law, to update or revise its forward-looking statements, whether as a result of new information, subsequent events, anticipated or unanticipated circumstances or otherwise.

ITEM 1. LEGAL PROCEEDINGS

        See Part I, Item 1, Note 8 to Condensed Consolidated Financial Statements, which is incorporated herein by reference.

ITEM 1A. RISK FACTORS

        There have been no material changes from the risk factors disclosed in Item 1A. Risk Factors of our Annual Report on Form 10-K for the year ended December 31, 2019, other than the following:

Outbreaks of communicable diseases can adversely affect our business, financial condition and results of operations.

        Global or national health concerns, including a widespread outbreak of contagious disease, can, among other impacts, negatively impact the global economy, reduce demand and pricing for crude oil, natural gas liquids (NGLs) and natural gas, lead to operational disruptions and limit our ability to execute on our business plan, any of which could materially and adversely affect our business, financial condition and results of operations. Furthermore, uncertainty regarding the impact of any outbreak of contagious disease could lead to increased volatility in crude oil, NGLs and natural gas prices.

For example, the current pandemic involving a highly transmissible and pathogenic coronavirus (COVID-19) and the measures being taken to address and limit the spread of the virus have adversely affected the economies and financial markets of the world, resulting in an economic downturn that has negatively impacted, and may continue to negatively impact, global demand and prices for crude oil and condensate, natural gas liquids (NGLs) and natural gas. The resulting decline in commodity prices has materially and adversely affected our cash flows and results of operations; if such decline were to continue for an extended period of time or worsen, our cash flows and results of operations would be further adversely affected. For further discussion regarding the potential impacts on us of lower commodity prices and extended declines in commodity prices, see ITEM 1A, Risk Factors, of our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, filed on February 27, 2020.

If the COVID-19 outbreak should continue or worsen, we may also experience disruptions to commodities markets, equipment supply chains and the availability of our workforce, which could adversely affect our ability to conduct our business and operations. Further, if the resulting economic downturn and adverse impact on commodity prices should continue or worsen, our customers and other contractual parties may be unable to pay amounts owed to us from time to time and to otherwise satisfy their contractual obligations to us, and may be unable to access the credit and capital markets for such purposes. Such inability of our customers and other contractual counterparties may materially and adversely affect our business, financial condition, results of operations and cash flows.

There are still too many variables and uncertainties regarding the COVID-19 pandemic - including the ultimate geographic spread of the virus, the duration and severity of the outbreak and the extent of travel restrictions and business closures imposed in affected countries - to fully assess the potential impact on our business, financial condition and results of operations.

Exhibit 95

Mine Safety Disclosure Exhibit

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act and the related rules promulgated thereunder by the United States Securities and Exchange Commission (SEC), each operator of a coal or other mine is required to disclose certain mine safety matters in its periodic reports filed with the SEC.

EOG Resources, Inc. (EOG) has sand mining operations in Texas and Wisconsin, which support EOG's exploration and development operations. EOG's sand mining operations are subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects mining facilities on a regular basis and issues citations and orders when it believes a violation has occurred under the Mine Act.

EOG was the operator of the following sand mining facilities during the quarter ended June 30, 2020:

•Hood County Sand Plant - Hood County, TX (MSHA ID 41-04696);

•

•Rawhide Sand Plant - Hood County, TX (MSHA ID 41-04777); and

•

•Chippewa Falls Sand Plant - Chippewa County, WI (MSHA ID 47-03624).

__________

During the quarter ended June 30, 2020, EOG did not receive any of the following from MSHA: (i) a citation for a violation of a mandatory health or safety standard that could significantly and substantially contribute to the cause and effect of a mine safety or health hazard under Section 104 of the Mine Act; (ii) an order issued under Section 104(b) of the Mine Act; (iii) a citation or order for unwarrantable failure to comply with mandatory health or safety standards under Section 104(d) of the Mine Act; (iv) written notice of a flagrant violation under Section 110(b)(2) of the Mine Act; (v) an imminent danger order issued under Section 107(a) of the Mine Act; (vi) any proposed assessments under the Mine Act; (vii) written notice of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of mine health or safety hazards under Section 104(e) of the Mine Act; or (viii) written notice of the potential to have such a pattern. Moreover, during the quarter ended June 30, 2020, EOG did not experience a mining-related fatality.

In addition, as of June 30, 2020, EOG did not have any legal action pending before the Federal Mine Safety and Health Review Commission (Mine Commission), and did not have any legal actions instituted or resolved before the Mine Commission during the quarter ended June 30, 2020.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

General. The condensed consolidated financial statements of EOG Resources, Inc., together with its subsidiaries (collectively, EOG), included herein have been prepared by management without audit pursuant to the rules and regulations of the United States Securities and Exchange Commission (SEC). Accordingly, they reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair presentation of the financial results for the interim periods presented. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations. However, management believes that the disclosures included either on the face of the financial statements or in these notes are sufficient to make the interim information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in EOG's Annual Report on Form 10-K for the year ended December 31, 2019, filed on February 27, 2020 (EOG's 2019 Annual Report).

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. Actual results could differ from those estimates. The operating results for the three and six months ended June 30, 2020, are not necessarily indicative of the results to be expected for the full year.

Effective January 1, 2020, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-13, "Measurement of Credit Losses on Financial Instruments" (ASU 2016-13). ASU 2016-13 changes the impairment model for financial assets and certain other instruments by requiring entities to adopt a forward-looking expected loss model that will result in earlier recognition of credit losses. EOG elected to adopt ASU 2016-13 using the modified retrospective approach with a cumulative-effect adjustment to retained earnings as of the effective date. Financial results reported in periods prior to January 1, 2020, are unchanged. EOG assessed its applicable financial assets, which are primarily its accounts receivable from hydrocarbon sales and joint interest billings to third-party companies, including foreign state-owned entities in the oil and gas industry. Based on its assessment and various potential remedies ensuring collection, EOG did not record an impact to retained earnings upon adoption and expects current and future credit losses to be immaterial. EOG continues to monitor the credit risk from third-party companies to determine if expected credit losses may become material.

Recently Issued Accounting Standards. In March 2020, the Financial Accounting Standards Board (FASB) issued ASU 2020-04, "Reference Rate Reform (Topic 848)" (ASU 2020-04), which provides optional expedients and exceptions for accounting treatment of contracts which are affected by the anticipated discontinuation of the London InterBank Offered Rate (LIBOR) and other rates resulting from rate reform. Contract terms that are modified due to the replacement of a reference rate are not required to be remeasured or reassessed under relevant accounting standards. Early adoption is permitted. ASU 2020-04 covers certain contracts which reference these rates and that are entered into on or before December 31, 2022. EOG is evaluating the provisions of ASU 2020-04 and has not determined the full impact on its consolidated financial statements and related disclosures related to its $2.0 billion senior unsecured Revolving Credit Agreement.

In December 2019, the FASB issued ASU 2019-12, "Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes" (ASU 2019-12), which amends certain aspects of accounting for income taxes. ASU 2019-12 removes specific exceptions within existing U.S. GAAP related to the incremental approach for intraperiod tax allocation and to the general methodology for calculating income taxes in interim periods, among other changes. ASU 2019-12 also requires an entity to reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, among other requirements. ASU 2019-12 is effective for interim and annual periods beginning after December 15, 2020, and early adoption is permitted. EOG is continuing to evaluate the provisions of ASU 2019-12 and has not determined the full impact on its consolidated financial statements and related disclosures.

Stock-Based Payments

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Stock-Based Compensation

As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2019 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the Condensed Consolidated Statements of Income (Loss) and Comprehensive Income (Loss) based upon the job function of the employees receiving the grants as follows (in millions):

	Three Months Ended June 30,				Six Months Ended June 30,
	2020		2019		2020		2019
Lease and Well	$	15.1	$	13.6	$	30.2	$	27.3
Gathering and Processing Costs	0.4		0.3		0.6		0.5
Exploration Costs	6.8		6.5		14.0		13.0
General and Administrative	17.3		18.2		34.8		36.9
Total	$	39.6	$	38.6	$	79.6	$	77.7

The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock and restricted stock units, performance units and other stock-based awards.

At June 30, 2020, approximately 7.0 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to 2008 Plan grants from previously authorized unissued shares or treasury shares to the extent treasury shares are available.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of stock option grants and SAR grants is estimated using the Hull-White II binomial option pricing model. The fair value of Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $15.0 million and $13.6 million during the three months ended June 30, 2020 and 2019, respectively, and $29.1 million and $27.5 million during the six months ended June 30, 2020 and 2019, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2020 and 2019 are as follows:

	Stock Options/SARs						ESPP
	Six Months Ended June 30,						Six Months Ended June 30,
	2020			2019			2020			2019
Weighted Average Fair Value of Grants	$	16.94		$	25.68		$	20.80		$	22.98
Expected Volatility	42.10		%	31.50		%	35.24		%	36.31		%
Risk-Free Interest Rate	0.93		%	2.38		%	1.56		%	2.48		%
Dividend Yield	1.94		%	0.96		%	1.56		%	0.83		%
Expected Life	5.1 years			5.1 years			0.5 years			0.5 years

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.

The following table sets forth stock option and SAR transactions for the six-month periods ended June 30, 2020 and 2019 (stock options and SARs in thousands):

	Six Months Ended June 30, 2020			Six Months Ended June 30, 2019
	Number of Stock Options/SARs	Weighted Average Grant Price		Number of Stock Options/SARs	Weighted Average Grant Price
Outstanding at January 1	9,395	$	94.53	8,310	$	96.90
Granted	16	58.40		32	93.29
Exercised (1)	(23)	69.59		(157)	73.39
Forfeited	(389)	91.39		(107)	105.47
Outstanding at June 30 (2)	8,999	$	94.66	8,078	$	97.23
Vested or Expected to Vest (3)	8,670	$	94.67	7,741	$	96.78
Exercisable at June 30 (4)	4,963	$	94.61	3,905	$	86.71

(1)The total intrinsic value of stock options/SARs exercised during the six months ended June 30, 2020 and 2019 was $0.4 million and $3.9 million, respectively. The intrinsic value is based upon the difference between the market price of EOG's common stock on the date of exercise and the grant price of the stock options/SARs.

(2)The total intrinsic value of stock options/SARs outstanding at June 30, 2020 and 2019 was $0.1 million and $45.0 million, respectively. At June 30, 2020 and 2019, the weighted average remaining contractual life was 3.9 years and 4.0 years, respectively.

(3)The total intrinsic value of stock options/SARs vested or expected to vest at June 30, 2020 and 2019 was $0.1 million and $44.4 million, respectively. At June 30, 2020 and 2019, the weighted average remaining contractual life was 3.9 years and 3.9 years, respectively.

(4)The total intrinsic value of stock options/SARs exercisable at June 30, 2020 and 2019 was zero and $37.1 million, respectively. At June 30, 2020 and 2019, the weighted average remaining contractual life was 2.7 years and 2.5 years, respectively.

At June 30, 2020, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $61.6 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.5 years.

Restricted Stock and Restricted Stock Units. Employees may be granted restricted (non-vested) stock and/or restricted stock units without cost to them. Stock-based compensation expense related to restricted stock and restricted stock units totaled $23.4 million and $23.1 million for the three months ended June 30, 2020 and 2019, respectively, and $48.2 million and $46.4 million for the six months ended June 30, 2020 and 2019, respectively.

The following table sets forth restricted stock and restricted stock unit transactions for the six-month periods ended June 30, 2020 and 2019 (shares and units in thousands):

	Six Months Ended June 30, 2020			Six Months Ended June 30, 2019
	Number of Shares and Units	Weighted Average Grant Date Fair Value		Number of Shares and Units	Weighted Average Grant Date Fair Value
Outstanding at January 1	4,546	$	90.16	3,792	$	96.64
Granted	67	51.83		401	96.22
Released (1)	(304)	88.58		(395)	93.84
Forfeited	(36)	90.61		(68)	98.27
Outstanding at June 30 (2)	4,273	$	89.67	3,730	$	96.86

(1)The total intrinsic value of restricted stock and restricted stock units released during the six months ended June 30, 2020 and 2019 was $13.1 million and $35.7 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the restricted stock and restricted stock units are released.

(2)The total intrinsic value of restricted stock and restricted stock units outstanding at June 30, 2020 and 2019 was $216.5 million and $347.5 million, respectively.

At June 30, 2020, unrecognized compensation expense related to restricted stock and restricted stock units totaled $154.2 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.4 years.

Performance Units. EOG grants performance units annually to its executive officers without cost to them. As more fully discussed in the grant agreements, the performance metric applicable to the performance units is EOG's total shareholder return over a three-year performance period relative to the total shareholder return of a designated group of peer companies (Performance Period). Upon the application of the performance multiple at the completion of the Performance Period, a minimum of 0% and a maximum of 200% of the performance units granted could be outstanding. The fair value of the performance units is estimated using a Monte Carlo simulation. Stock-based compensation expense related to the performance unit grants totaled $1.2 million and $1.9 million for the three months ended June 30, 2020 and 2019, respectively, and $2.3 million and $3.8 million for the six months ended June 30, 2020 and 2019, respectively.

The following table sets forth the performance unit transactions for the six-month periods ended June 30, 2020 and 2019 (units in thousands):

	Six Months Ended June 30, 2020				Six Months Ended June 30, 2019
	Number of Units		Weighted Average Price per Grant Date		Number of Units	Weighted Average Price per Grant Date
Outstanding at January 1	598		$	92.19	539	$	101.53
Granted	—		—		—	—
Granted for Performance Multiple (1)	66		100.95		72	69.43
Released (2)	(121)		104.69		(83)	85.65
Forfeited	—		—		—	—
Outstanding at June 30 (3)	543	(4)	$	90.48	528	$	99.64

(1)Upon completion of the Performance Period for the performance units granted in 2016 and 2015, a performance multiple of 150% and 200%, respectively, was applied to each of the grants resulting in additional grants of performance units in February 2020 and February 2019, respectively.

(2)The total intrinsic value of performance units released during the six months ended June 30, 2020 and 2019 was $9.0 million and $7.7 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date the performance units are released.

(3)The total intrinsic value of performance units outstanding at June 30, 2020 and 2019 was approximately $27.5 million and $49.2 million, respectively.

(4)Upon the application of the relevant performance multiple at the completion of each of the remaining Performance Periods, a minimum of 179 and a maximum of 907 performance units could be outstanding.

At June 30, 2020, unrecognized compensation expense related to performance units totaled $6.4 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.7 years.

Long-Term Debt and Common Stock

Debt Disclosure [Abstract]

Long-Term Debt and Common Stock

Long-Term Debt and Common Stock

Long-Term Debt. EOG had no outstanding commercial paper borrowings at June 30, 2020 and December 31, 2019, and did not utilize any commercial paper borrowings during the six months ended June 30, 2020 and 2019.

At June 30, 2020, $750 million aggregate principal amount of EOG's 4.100% Senior Notes due 2021 was reclassified as long-term debt as a result of EOG's intent and ability to ultimately replace such amounts with other long-term debt.

EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders (Banks). The Agreement has a scheduled maturity date of June 27, 2024, and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods subject to certain terms and conditions. The Agreement (i) commits the Banks to provide advances up to an aggregate principal amount of $2.0 billion at any one time outstanding, with an option for EOG to request increases in the aggregate commitments to an amount not to exceed $3.0 billion, subject to certain terms and conditions and (ii) includes a swingline subfacility and a letter of credit subfacility. Advances under the Agreement will accrue interest based, at EOG's option, on either LIBOR plus an applicable margin (Eurodollar rate) or the base rate (as defined in the Agreement) plus an applicable margin. The Agreement contains representations, warranties, covenants and events of default that EOG believes are customary for investment-grade, senior unsecured commercial bank credit agreements, including a financial covenant for the maintenance of a ratio of total debt-to-total capitalization (as such terms are defined in the Agreement) of no greater than 65%. At June 30, 2020, EOG was in compliance with this financial covenant. At June 30, 2020 and December 31, 2019, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and base rate (inclusive of the applicable margin), had there been any amounts borrowed under the Agreement at June 30, 2020, would have been 1.06% and 3.25%, respectively.

On April 1, 2020, EOG repaid upon maturity the $500 million aggregate principal amount of its 2.45% Senior Notes due 2020.

On April 14, 2020, EOG closed on its offering of $750 million aggregate principal amount of its 4.375% Senior Notes due 2030 and $750 million aggregate principal amount of its 4.950% Senior Notes due 2050 (together, the Notes). Interest on the Notes is payable semi-annually in arrears on April 15 and October 15 of each year, beginning on October 15, 2020. EOG received net proceeds of approximately $1.48 billion from the issuance of the Notes, which were used to repay the 4.40% Senior Notes due 2020 when they matured on June 1, 2020 (see below), and have also been used (and will continue to be used) for general corporate purposes, including the funding of capital expenditures.

On June 1, 2020, EOG repaid upon maturity the $500 million aggregate principal amount of its 4.40% Senior Notes due 2020.

Common Stock. On February 27, 2020, EOG's Board of Directors increased the quarterly cash dividend on the common stock from the previous $0.2875 per share to $0.375 per share, effective beginning with the dividend paid on April 30, 2020, to stockholders of record as of April 16, 2020.

The estimated fair value of commodity derivative contracts was based upon forward commodity price curves based on quoted market prices. Commodity derivative contracts were valued by utilizing an independent third-party derivative valuation provider who uses various types of valuation models, as applicable.

Non-Recurring Fair Value Measurements. The initial measurement of asset retirement obligations at fair value is calculated using discounted cash flow techniques and based on internal estimates of future retirement costs associated with property, plant and equipment. Significant Level 3 inputs used in the calculation of asset retirement obligations include plugging costs and reserve lives. A reconciliation of EOG's asset retirement obligations is presented in Note 6.

When circumstances indicate that proved oil and gas properties may be impaired, EOG compares expected undiscounted future cash flows at a depreciation, depletion and amortization group level to the unamortized capitalized cost of the asset. If the expected undiscounted future cash flows, based on EOG's estimate of (and assumptions regarding) future crude oil and natural gas prices, operating costs, development expenditures, anticipated production from proved reserves and other relevant data, are lower than the unamortized capitalized cost, the capitalized cost is reduced to fair value. Fair value is generally calculated using the Income Approach described in the Fair Value Measurement Topic of the ASC. In certain instances, EOG utilizes accepted offers from third-party purchasers as the basis for determining fair value.

During the first half of 2020, due to the decline in commodity prices, proved oil and gas properties with a carrying amount of $1,424 million were written down to their fair value of $264 million, resulting in pretax impairment charges of $1,160 million for the six months ended June 30, 2020. In addition, EOG recorded pretax impairment charges of $72 million for the six months ended June 30, 2020, for a commodity price-related write-down of other assets.

EOG utilized average prices per acre from comparable market transactions and estimated discounted cash flows as the basis for determining the fair value of unproved and proved properties, respectively, received in non-cash property exchanges. See Note 4.

Fair Value Disclosures. EOG's financial instruments, other than commodity derivative contracts, consist of cash and cash equivalents, accounts receivable, accounts payable and current and long-term debt. The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate fair value.

At June 30, 2020 and December 31, 2019, respectively, EOG had outstanding $5,640 million and $5,140 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $6,416 million and $5,452 million, respectively. The estimated fair value of debt was based upon quoted market prices and, where such prices were not available, other observable (Level 2) inputs regarding interest rates available to EOG at the end of each respective period.

Risk Management Activities

Risk Management Activities

Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2019 Annual Report, EOG engages in price risk management activities from time to time. These activities are intended to manage EOG's exposure to fluctuations in commodity prices for crude oil, NGLs and natural gas. EOG utilizes financial commodity derivative instruments, primarily price swap, option, swaption, collar and basis swap contracts, as a means to manage this price risk. EOG has not designated any of its financial commodity derivative contracts as accounting hedges and, accordingly, accounts for financial commodity derivative contracts using the mark-to-market accounting method.

Crude Oil Derivative Contracts. Prices received by EOG for its crude oil production generally vary from U.S. New York Mercantile Exchange (NYMEX) West Texas Intermediate (WTI) prices due to adjustments for delivery location (basis) and other factors. EOG has entered into crude oil basis swap contracts in order to fix the differential between Intercontinental Exchange (ICE) Brent pricing and pricing in Cushing, Oklahoma (ICE Brent Differential). Presented below is a comprehensive summary of EOG's ICE Brent Differential basis swap contracts as of June 30, 2020. The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of addition to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

EOG has also entered into natural gas basis swap contracts in order to fix the differential between pricing at the Waha Hub in West Texas and NYMEX Henry Hub prices (Waha Differential). Presented below is a comprehensive summary of EOG's Waha Differential basis swap contracts as of June 30, 2020. The weighted average price differential expressed in $/MMBtu represents the amount of reduction to NYMEX Henry Hub prices for the notional volumes expressed in MMBtud covered by the basis swap contracts.

2020
January 1, 2020 through April 30, 2020 (closed)	50,000	$	1.40

In April 2020, EOG entered into Waha Differential basis swap contracts for the period from May 1, 2020 through December 31, 2020, with notional volumes of 50,000 MMBtud at a weighted average price differential of $0.43 per MMBtu. These contracts offset the remaining Waha Differential basis swap contracts for the same time period with notional volumes of 50,000 MMBtud at a weighted average price differential of $1.40 per MMBtu. EOG expects to pay net cash of $11.9 million for the settlement of these contracts. The offsetting contracts were excluded from the above table.

Commodity Derivatives Location on Balance Sheet. The following table sets forth the amounts and classification of EOG's outstanding financial derivative instruments at June 30, 2020 and December 31, 2019.  Certain amounts may be presented on a net basis on the Condensed Consolidated Financial Statements when such amounts are with the same counterparty and subject to a master netting arrangement (in thousands):

(1) The current portion of Assets from Price Risk Management Activities consists of gross assets of $239 million, partially offset by gross liabilities of $32 million at June 30, 2020. The current portion of Assets from Price Risk Management Activities consists of gross assets of $3 million, partially offset by gross liabilities of $2 million, at December 31, 2019.

(2) The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $23 million, partially offset by gross assets of $3 million, at December 31, 2019.

Credit Risk. Notional contract amounts are used to express the magnitude of a financial derivative. The amounts potentially subject to credit risk, in the event of nonperformance by the counterparties, are equal to the fair value of such contracts (see Note 11). EOG evaluates its exposure to significant counterparties on an ongoing basis, including that arising from physical and financial transactions. In some instances, EOG renegotiates payment terms and/or requires collateral, parent guarantees or letters of credit to minimize credit risk.

All of EOG's derivative instruments are covered by International Swap Dealers Association Master Agreements (ISDAs) with counterparties. The ISDAs may contain provisions that require EOG, if it is the party in a net liability position, to post collateral when the amount of the net liability exceeds the threshold level specified for EOG's then-current credit ratings. In addition, the ISDAs may also provide that as a result of certain circumstances, including certain events that cause EOG's credit ratings to become materially weaker than its then-current ratings, the counterparty may require all outstanding derivatives under the ISDAs to be settled immediately. See Note 11 for the aggregate fair value of all derivative instruments that were in a net asset position at June 30, 2020 and December 31, 2019. EOG had no collateral posted and held collateral of $62 million at June 30, 2020, and had no collateral posted and held no collateral at December 31, 2019.

The collars require that EOG pay the difference between the ceiling price and the NYMEX Henry Hub natural gas price for the contract month (Henry Hub Index Price) in the event the Henry Hub Index Price is above the ceiling price. The collars grant EOG the right to receive the difference between the floor price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the floor price. In March 2020, EOG executed the early termination provision granting EOG the right to terminate certain 2020 natural gas collar contracts with notional volumes of 250,000 MMBtud at a weighted average ceiling price of $2.50 per MMBtu and a weighted average floor price of $2.00 per MMBtu for the period from April 1, 2020 through July 31, 2020. The net cash EOG received for settling these contracts was $7.8 million. Presented below is a comprehensive summary of EOG's natural gas collar contracts as of June 30, 2020, with notional volumes expressed in MMBtud and prices expressed in $/MMBtu.
