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, 2018 , filed on February 26, 2019 (EOG's 2018 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, 2019 , are not necessarily indicative of the results to be expected for the full year. Effective January 1, 2019, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-02, "Leases (Topic 842)" (ASU 2016-02). ASU 2016-02 and other related ASUs require that lessees recognize a right-of-use (ROU) asset and related lease liability, representing the obligation to make lease payments for certain lease transactions, on the Condensed Consolidated Balance Sheets and disclose additional leasing information. EOG elected to adopt ASU 2016-02 and other related ASUs using the modified retrospective approach with a cumulative-effect adjustment to the opening balance of retained earnings as of the effective date. Financial results reported in periods prior to January 1, 2019, are unchanged. Additionally, EOG elected the package of practical expedients within ASU 2016-02 that allows an entity to not reassess prior to the effective date (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases, or (iii) initial direct costs for any existing leases, but did not elect the practical expedient of hindsight when determining the lease term of existing contracts at the effective date. EOG also elected the practical expedient under ASU 2018-01, "Leases (Topic 842) - Land Easement Practical Expedient for Transition to Topic 842," and did not evaluate existing or expired land easements not previously accounted for as leases prior to the January 1, 2019 effective date. There was no impact to retained earnings upon adoption of ASU 2016-02 and other related ASUs. See Note 14.

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 2018 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 Six Months Ended 2019 2018 2019 2018 Lease and Well $ 13.6 $ 11.4 $ 27.3 $ 24.2 Gathering and Processing Costs 0.3 0.1 0.5 0.2 Exploration Costs 6.5 5.7 13.0 12.6 General and Administrative 18.2 14.6 36.9 30.3 Total $ 38.6 $ 31.8 $ 77.7 $ 67.3 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, 2019 , approximately 13.0 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 $13.6 million and $11.7 million during the three months ended June 30, 2019 and 2018 , respectively, and $27.5 million and $23.7 million during the six months ended June 30, 2019 and 2018 , 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, 2019 and 2018 are as follows: Stock Options/SARs ESPP Six Months Ended Six Months Ended 2019 2018 2019 2018 Weighted Average Fair Value of Grants $ 25.68 $ 29.18 $ 22.98 $ 23.27 Expected Volatility 31.50 % 28.88 % 36.31 % 22.04 % Risk-Free Interest Rate 2.38 % 2.23 % 2.48 % 1.60 % Dividend Yield 0.96 % 0.67 % 0.83 % 0.66 % Expected Life 5.1 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 six -month periods ended June 30, 2019 and 2018 (stock options and SARs in thousands): Six Months Ended Six Months Ended Number of Stock Options/SARs Weighted Average Grant Price Number of Stock Options/SARs Weighted Average Grant Price Outstanding at January 1 8,310 $ 96.90 9,103 $ 83.89 Granted 32 93.29 32 110.17 Exercised (1) (157 ) 73.39 (1,662 ) 71.33 Forfeited (107 ) 105.47 (124 ) 92.07 Outstanding at June 30 (2) 8,078 $ 97.23 7,349 $ 86.71 Vested or Expected to Vest (3) 7,741 $ 96.78 7,006 $ 86.44 Exercisable at June 30 (4) 3,905 $ 86.71 2,938 $ 78.74 (1) The total intrinsic value of stock options/SARs exercised during the six months ended June 30, 2019 and 2018 was $3.9 million and $74.5 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, 2019 and 2018 was $45.0 million and $277.2 million , respectively. At June 30, 2019 and 2018 , the weighted average remaining contractual life was 4.0 years and 4.3 years , respectively. (3) The total intrinsic value of stock options/SARs vested or expected to vest at June 30, 2019 and 2018 was $44.4 million and $266.2 million , respectively. At June 30, 2019 and 2018 , the weighted average remaining contractual life was 3.9 years and 4.3 years , respectively. (4) The total intrinsic value of stock options/SARs exercisable at June 30, 2019 and 2018 was $37.1 million and $134.2 million , respectively. At June 30, 2019 and 2018 , the weighted average remaining contractual life was 2.5 years and 2.7 years , respectively. At June 30, 2019 , unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $81.3 million . Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.6 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 $23.1 million and $19.0 million for the three months ended June 30, 2019 and 2018, respectively, and $46.4 million and $41.3 million for the six months ended June 30, 2019 and 2018 , respectively. The following table sets forth restricted stock and restricted stock unit transactions for the six -month periods ended June 30, 2019 and 2018 (shares and units in thousands): Six Months Ended Six Months Ended 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 3,792 $ 96.64 3,905 $ 88.57 Granted 401 96.22 309 103.52 Released (1) (395 ) 93.84 (331 ) 69.55 Forfeited (68 ) 98.27 (120 ) 91.28 Outstanding at June 30 (2) 3,730 $ 96.86 3,763 $ 91.39 (1) The total intrinsic value of restricted stock and restricted stock units released during the six months ended June 30, 2019 and 2018 was $35.7 million and $34.9 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, 2019 and 2018 was $347.5 million and $468.2 million , respectively. At June 30, 2019 , unrecognized compensation expense related to restricted stock and restricted stock units totaled $158.2 million . Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.7 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 $1.9 million and $1.1 million for the three months ended June 30, 2019 and 2018 , respectively, and $3.8 million and $2.3 million for the six months ended June 30, 2019 and 2018 , respectively.

(2) The total intrinsic value of performance units released during the six months ended June 30, 2019 , was $7.7 million . 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, 2019 and 2018 was approximately $49.2 million and $71.4 million , respectively. (4) Upon the application of the relevant performance multiple at the completion of each of the remaining Performance Periods, a minimum of 205 and a maximum of 852 performance units could be outstanding. At June 30, 2019 , unrecognized compensation expense related to performance units totaled $6.0 million . Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 1.2 years .

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 or uncommitted credit facility borrowings at June 30, 2019 and December 31, 2018, and did not utilize any such borrowings during the six months ended June 30, 2019 . During the six months ended June 30, 2018, EOG utilized commercial paper borrowings, bearing market interest rates, for various corporate financing purposes. The average borrowings outstanding under the commercial paper program was $17 million during the six months ended June 30, 2018. The weighted average interest rate for commercial paper borrowings during the six months ended June 30, 2018, was 1.97% . On June 3, 2019, EOG repaid upon maturity the $900 million aggregate principal amount of its 5.625% Senior Notes due 2019. On June 27, 2019, EOG entered into a new $2.0 billion senior unsecured Revolving Credit Agreement (New Facility) with domestic and foreign lenders (Banks). The New Facility replaces EOG’s $2.0 billion senior unsecured Revolving Credit Agreement, dated as of July 21, 2015, with domestic and foreign lenders (2015 Facility), which had a scheduled maturity date of July 21, 2020 and which was terminated by EOG (without penalty), effective as of June 27, 2019, in connection with the completion of the New Facility. The New Facility 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 New Facility (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 New Facility will accrue interest based, at EOG’s option, on either the London InterBank Offered Rate plus an applicable margin (Eurodollar Rate) or the Base Rate (as defined in the New Facility) plus an applicable margin. The applicable margin used in connection with interest rates and fees will be based on EOG’s credit rating for its senior unsecured long-term debt at the applicable time. Consistent with the terms of the 2015 Facility, the New Facility contains representations, warranties, covenants and events of default that we believe 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 New Facility) of no greater than 65% . At June 30, 2019, EOG was in compliance with this financial covenant. There were no borrowings or letters of credit outstanding under the 2015 Facility as of (i) December 31, 2018 or (ii) the June 27, 2019 effective date of the closing of the New Facility and termination of the 2015 Facility. Further, at June 30, 2019, there were no borrowings or letters of credit outstanding under the New Facility. The Eurodollar Rate and Base Rate (inclusive of the applicable margin), had there been any amounts borrowed under the New Facility at June 30, 2019, would have been 3.30% and 5.50% , respectively. Common Stock. On May 2, 2019, EOG's Board of Directors increased the quarterly cash dividend on the common stock from the previous $0.22 per share to $0.2875 per share, effective beginning with the dividend to be paid on July 31, 2019, to stockholders of record as of July 17, 2019.

Fair Value Measurements	Fair Value Measurements As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2018 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, 2019 and December 31, 2018 (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 June 30, 2019 Financial Assets: Natural Gas Swaps $ — $ 18,507 $ — $ 18,507 Crude Oil Swaps — 118,854 — 118,854 Crude Oil Basis Swaps — 867 — 867 Financial Liabilities: Crude Oil Basis Swaps $ — $ 3,277 $ — $ 3,277 At December 31, 2018 Financial Assets: Crude Oil Basis Swaps $ — $ 23,806 $ — $ 23,806 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. 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. Proved oil and gas properties and other assets with a carrying amount of $413 million were written down to their fair value of $322 million , resulting in pretax impairment charges of $91 million for the six months ended June 30, 2019 . Included in the $91 million pretax impairment charges are $89 million 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 of Debt. At June 30, 2019 and December 31, 2018 , respectively, EOG had outstanding $5,140 million and $6,040 million aggregate principal amount of senior notes, which had estimated fair values at such dates of approximately $5,387 million and $6,027 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 2018 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 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. Commodity Derivative Contracts. Prices received by EOG for its crude oil production generally vary from U.S. New York Mercantile Exchange (NYMEX) West Texas Intermediate 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 pricing in Midland, Texas, and Cushing, Oklahoma (Midland Differential). Presented below is a comprehensive summary of EOG's Midland Differential basis swap contracts for the six months ended June 30, 2019 . The weighted average price differential expressed in dollars per barrel ($/Bbl) represents the amount of reduction to Cushing, Oklahoma, prices for the notional volumes expressed in barrels per day (Bbld) covered by the basis swap contracts.

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 those 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, 2019 and December 31, 2018 . EOG had no collateral posted and held collateral of $4 million at June 30, 2019 . EOG had no collateral posted or held at December 31, 2018 .

Leases [Abstract]
Lessee Operating and Finance Leases	Leases In the ordinary course of business, EOG enters into contracts for drilling, fracturing, compression, real estate and other services which contain equipment and other assets that meet the definition of a lease under ASU 2016-02. The lease term for these contracts, which includes any renewals at EOG's option that are reasonably certain to be exercised, ranges from one month to 30 years. ROU assets and related liabilities are recognized on commencement date on the Condensed Consolidated Balance Sheets based on future lease payments, discounted based on the rate implicit in the contract, if readily determinable, or EOG's incremental borrowing rate commensurate with the lease term of the contract. Contracts with lease terms less than 12 months are not recorded on the Condensed Consolidated Balance Sheets, but instead are disclosed as short-term lease cost. EOG has elected not to separate non-lease components from all leases, excluding those for fracturing services, real estate and salt water disposal, as lease payments for these contracts contain significant non-lease components, such as labor and operating costs. Lease costs are classified by the function of the ROU asset. The lease costs related to exploration and development activities are initially included in the Oil and Gas Properties line on the Condensed Consolidated Balance Sheets and subsequently accounted for in accordance with the Extractive Industries - Oil and Gas Topic of the Accounting Standards Codification. Variable lease cost represents costs incurred above the contractual minimum payments for operating and finance leases. The components of lease cost for the three month and six month periods ended June 30, 2019 , were as follows (in millions): Three Months Ended Six Months Ended Operating Lease Cost $ 134 $ 253 Finance Lease Cost: Amortization of Lease Assets 4 7 Interest on Lease Liabilities — 1 Variable Lease Cost 97 128 Short-Term Lease Cost 157 228 Total Lease Cost $ 392 $ 617 The following table sets forth the amounts and classification of EOG's outstanding ROU assets and related lease liabilities and supplemental information at June 30, 2019 (in millions, except lease terms and discount rates): Description Location on Balance Sheet Amount Assets Operating Leases Other Assets $ 895 Finance Leases Property, Plant and Equipment, Net (1) 59 Total $ 954 Liabilities Current Operating Leases Current Portion of Operating Lease Liabilities $ 397 Finance Leases Current Portion of Long-Term Debt 15 Long-Term Operating Leases Other Liabilities 527 Finance Leases Long-Term Debt 49 Total $ 988 (1) Finance lease assets are recorded net of accumulated amortization of $53 million at June 30, 2019 .
