Summary of Significant Accounti

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 Six Months Ended 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 Six Months Ended 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.

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.

Fair Value Measurements	Fair Value Measurements Recurring Fair Value Measurements. As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2019 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the Condensed Consolidated Balance Sheets. The following table provides fair value measurement information within the fair value hierarchy for certain of EOG's financial assets and liabilities carried at fair value on a recurring basis at June 30, 2020 and December 31, 2019 (in thousands): Fair Value Measurements Using: Quoted Significant Significant Total At June 30, 2020 Financial Assets: (1) Crude Oil Swaps $ — $ 224,256 $ — $ 224,256 Crude Oil Roll Differential Swaps — 2,396 — 2,396 Natural Gas Liquids Swaps — 7,064 — 7,064 Natural Gas Collars — 4,338 — 4,338 Natural Gas Swaps — 2,533 — 2,533 Natural Gas Basis Swaps — 6 — 6 Financial Liabilities: Crude Oil Roll Differential Swaps $ — $ 16,855 $ — $ 16,855 Natural Gas Basis Swaps — 10,671 — 10,671 Natural Gas Liquids Swaps — 166 — 166 Natural Gas Collars — 4,313 — 4,313 At December 31, 2019 Financial Assets: (1) Natural Gas Liquids Swaps $ — $ 3,401 $ — $ 3,401 Natural Gas Basis Swaps — 970 — 970 Financial Liabilities: (2) Crude Oil Swaps $ — $ 23,266 $ — $ 23,266 (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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
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.
