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 months ended March 31, 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 Compensation (Notes

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 and Comprehensive Income based upon the job function of the employees receiving the grants as follows (in millions): Three Months Ended March 31, 2020 2019 Lease and Well $ 15.1 $ 13.7 Gathering and Processing Costs 0.3 0.2 Exploration Costs 7.2 6.5 General and Administrative 17.5 18.7 Total $ 40.1 $ 39.1 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 March 31, 2020 , approximately 6.7 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 $14.1 million and $13.9 million during the three months ended March 31, 2020 and 2019 , respectively. Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the three -month periods ended March 31, 2020 and 2019 are as follows: Stock Options/SARs ESPP Three Months Ended March 31, Three Months Ended March 31, 2020 2019 2020 2019 Weighted Average Fair Value of Grants $ 19.67 $ 27.19 $ 20.80 $ 22.98 Expected Volatility 33.43 % 31.81 % 35.24 % 36.31 % Risk-Free Interest Rate 1.43 % 2.51 % 1.56 % 2.48 % Dividend Yield 1.60 % 0.88 % 1.56 % 0.83 % Expected Life 5.0 years 5.0 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 three -month periods ended March 31, 2020 and 2019 (stock options and SARs in thousands): Three Months Ended March 31, 2020 Three Months Ended March 31, 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 9 75.44 17 96.67 Exercised (1) (23 ) 69.59 (43 ) 69.94 Forfeited (47 ) 96.81 (48 ) 105.43 Outstanding at March 31 (2) 9,334 $ 94.56 8,236 $ 96.99 Vested or Expected to Vest (3) 8,998 $ 94.55 7,892 $ 96.53 Exercisable at March 31 (4) 5,249 $ 94.33 3,997 $ 86.25 (1) The total intrinsic value of stock options/SARs exercised during the three months ended March 31, 2020 and 2019 was $0.4 million and $1.1 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 March 31, 2020 and 2019 was zero and $51.8 million , respectively. At March 31, 2020 and 2019 , the weighted average remaining contractual life was 4.0 years and 4.2 years , respectively. (3) The total intrinsic value of stock options/SARs vested or expected to vest at March 31, 2020 and 2019 was zero and $51.1 million , respectively. At March 31, 2020 and 2019 , the weighted average remaining contractual life was 4.0 years and 4.1 years , respectively. (4) The total intrinsic value of stock options/SARs exercisable at March 31, 2020 and 2019 was zero and $43.1 million , respectively. At March 31, 2020 and 2019 , the weighted average remaining contractual life was 2.8 years and 2.7 years , respectively. At March 31, 2020 , unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $74.9 million . Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.7 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 $24.8 million and $23.3 million for the three months ended March 31, 2020 and 2019 , respectively. The following table sets forth restricted stock and restricted stock unit transactions for the three -month periods ended March 31, 2020 and 2019 (shares and units in thousands): Three Months Ended March 31, 2020 Three Months Ended March 31, 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 26 63.48 371 96.72 Released (1) (259 ) 88.19 (247 ) 93.37 Forfeited (11 ) 89.86 (26 ) 98.11 Outstanding at March 31 (2) 4,302 $ 90.12 3,890 $ 96.85 (1) The total intrinsic value of restricted stock and restricted stock units released during the three months ended March 31, 2020 and 2019 was $11.0 million and $22.0 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 March 31, 2020 and 2019 was $154.5 million and $370.2 million , respectively. At March 31, 2020 , unrecognized compensation expense related to restricted stock and restricted stock units totaled $177.8 million . Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 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.

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 March 31, 2020 and December 31, 2019, and did not utilize any commercial paper borrowings during the three months ended March 31, 2020 and 2019. At March 31, 2020, $500 million aggregate principal amount of EOG's 4.40% Senior Notes due 2020 and $750 million aggregate principal amount of EOG's 4.10% Senior Notes due 2021 were 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 March 31, 2020, EOG was in compliance with this financial covenant. At March 31, 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 March 31, 2020, would have been 1.89% 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 will be used for general corporate purposes, including the funding of future capital expenditures and the repayment of the 4.40% Senior Notes due 2020 when they mature on June 1, 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.

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 March 31, 2020 and December 31, 2019 (in thousands): Fair Value Measurements Using: Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total At March 31, 2020 Financial Assets: (1) Crude Oil Swaps $ — $ 898,090 $ — $ 898,090 Crude Oil Basis Swaps — 888 — 888 Crude Oil Roll Differential Swaps — 7,255 — 7,255 Natural Gas Liquids Swaps — 30,822 — 30,822 Natural Gas Collars — 3,678 — 3,678 Financial Liabilities: Crude Oil Basis Swaps $ — $ 93 $ — $ 93 Natural Gas Basis Swaps — 7,712 — 7,712 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) $ 933 million and $ 1 million are included in "Current Assets - Assets from Price Risk Management Activities" at March 31, 2020 and December 31, 2019, respectively, 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. During the three months ended March 31, 2020, due to the decline in commodity prices, proved oil and gas properties, leasehold costs and other assets with a carrying amount of $1,813 million were written down to their fair value of $357 million , resulting in pretax impairment charges of $1,456 million for the three months ended March 31, 2020 . 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 March 31, 2020 and December 31, 2019 , EOG had outstanding $5,140 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,145 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 March 31, 2020.

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. On March 24, 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 million British thermal units (MMBtu) per day (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 April 1, 2020 through July 31, 2020.

(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 March 31, 2020 and December 31, 2019 . EOG had no collateral posted and held collateral of $ 762 million at March 31, 2020 , and had no collateral posted and held no collateral at December 31, 2019 .
