Summary of Significant Accounting Policies	3 Months Ended
	Mar. 31, 2017
Accounting Policies [Abstract]
Summary of Significant Accounting Policies [Text Block]	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, 2016, filed on February 27, 2017 (EOG's 2016 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, 2017, are not necessarily indicative of the results to be expected for the full year. Effective January 1, 2017, EOG adopted the provisions of Accounting Standards Update (ASU) 2016-09, "Improvements to Employee Share-Based Payment Accounting" (ASU 2016-09), which amends certain aspects of accounting for share-based payment arrangements. ASU 2016-09 revises or provides alternative accounting for the tax impacts of share-based payment arrangements, forfeitures and minimum statutory tax withholdings and prescribes certain disclosures to be made in the period the new standard is adopted. There was no impact to retained earnings with respect to excess tax benefits. EOG began recognizing all excess benefits and tax deficiencies as income tax expense or benefit as discrete events. The treatment of forfeitures did not change as EOG elected to continue the current process of estimating the number of forfeitures. As such, this had no cumulative effect on retained earnings. EOG elected to present changes to the statements of cash flows on a prospective transition method. Effective January 1, 2017, EOG adopted the provisions of ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes" (ASU 2015-17), which simplifies the presentation of deferred taxes in a classified balance sheet by eliminating the requirement to separate deferred income tax liabilities and assets into current and noncurrent amounts. Instead, ASU 2015-17 requires that all deferred tax liabilities and assets be shown as noncurrent in a classified balance sheet. In connection with the adoption of ASU 2015-17, EOG restated its December 31, 2016 balance sheet to reclassify $169 million of current deferred income tax assets as noncurrent. Recently Issued Accounting Standards. In February 2017, the Financial Accounting Standards Board (FASB) issued ASU 2017-05 “Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (ASU 2017-05). ASU 2017-05 clarifies the scope and application of ASC 610-20 to the sale or transfer of nonfinancial assets and, in substance, nonfinancial assets to noncustomers, including partial sales. ASU 2017-05 is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted, at the same time of adoption of ASU 2014-09, “Revenue From Contracts With Customers” (ASU 2014-09). EOG does not intend to early adopt ASU 2017-05. EOG is reviewing the provisions of ASU 2017-05 in connection with the adoption of ASU 2014-09 to determine its impact on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-01 "Business Combinations (Topic 805): Clarifying the Definition of a Business" (ASU 2017-01), which clarifies the definition of a business to provide guidance in evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. ASU 2017-01 provides a screen to determine when a set of assets is not a business, requiring that when substantially all fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset or group of similar identifiable assets, the set of assets is not a business. A framework is provided to assist in evaluating whether both an input and a substantive process are present for the set to be a business. ASU 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. No disclosures are required at transition and early adoption is permitted. EOG is evaluating ASU 2017-01 to determine the impact on its consolidated financial statements and related disclosures. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments” (ASU 2016-15).  ASU 2016-15 reduces existing diversity in practice by providing guidance on the classification of eight specific cash receipts and cash payments transactions in the statement of cash flows.  The new standard is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years.  Early adoption is permitted.  EOG does not expect the adoption of the new standard to have a material impact on its consolidated financial statements and related disclosures.    In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)" (ASU 2016-02), which significantly changes accounting for leases by requiring that lessees recognize a right-of-use asset and a related lease liability representing the obligation to make lease payments, for virtually all lease transactions. Additional disclosures about an entity's lease transactions will also be required. ASU 2016-02 defines a lease as "a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration." ASU 2016-02 is effective for interim and annual periods beginning after December 31, 2018 and early application is permitted. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. EOG is reviewing the provisions of ASU 2016-02 to determine the impact on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, which will require entities to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 will supersede most current guidance related to revenue recognition when it becomes effective. The new standard also will require expanded disclosures regarding the nature, amount, timing and certainty of revenue and cash flows from contracts with customers. ASU 2014-09 is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted.  The new standard permits adoption through the use of either the full retrospective approach or a modified retrospective approach.  In May 2016, the FASB issued ASU 2016-11 which rescinds certain SEC guidance in the related Accounting Standards Codification, including guidance related to the use of the "entitlements" method of revenue recognition used by EOG. EOG does not intend to early-adopt ASU 2014-09 and has not determined which transition method it will use. EOG has conducted an assessment of its contracts with customers, identified implementation matters and continues to analyze ASU 2014-09 in order to determine the impact, if any, on EOG's consolidated financial statements and related disclosures.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation [Text Block]	Stock-Based Compensation As more fully discussed in Note 7 to the Consolidated Financial Statements included in EOG's 2016 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   March 31,   2017   2016 Lease and Well $ 10.9   $ 10.4 Gathering and Processing Costs 0.2   0.3 Exploration Costs 6.2   6.5 General and Administrative 13.2   15.2 Total $ 30.5   $ 32.4 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 performance stock and other stock-based awards. At March 31, 2017, approximately 20.7 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to the 2008 Plan 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 $11.0 million and $13.2 million during the three months ended March 31, 2017 and 2016, 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, 2017 and 2016 are as follows:   Stock Options/SARs   ESPP   Three Months Ended   March 31,   Three Months Ended   March 31,   2017   2016   2017   2016 Weighted Average Fair Value of Grants $ 29.13   $ 20.87   $ 24.28   $ 17.56 Expected Volatility 31.67 %   36.45 %   30.33 %   36.79 % Risk-Free Interest Rate 1.36 %   1.03 %   0.65 %   0.49 % Dividend Yield 0.67 %   0.86 %   0.69 %   0.82 % Expected Life 5.3 years   5.3 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, 2017 and 2016 (stock options and SARs in thousands):   Three Months Ended   March 31, 2017   Three Months Ended   March 31, 2016   Number of Stock Options/SARs   Weighted Average Grant Price   Number of Stock Options/SARs   Weighted Average Grant Price Outstanding at January 1 9,850   $ 75.53   10,744   $ 67.98 Granted 5   101.61   5   69.03 Exercised (1) (600 )   57.53   (258 )   43.44 Forfeited (99 )   88.57   (60 )   85.65 Outstanding at March 31 (2) 9,156   $ 76.59   10,431   $ 68.48 Vested or Expected to Vest (3) 8,849   $ 76.20   10,060   $ 68.04 Exercisable at March 31 (4) 5,078   $ 67.74   5,770   $ 58.68 (1) The total intrinsic value of stock options/SARs exercised for the three months ended March 31, 2017 and 2016 was $26.6 million and $7.3 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, 2017 and 2016 was $199.3 million and $122.1 million, respectively. At March 31, 2017 and 2016, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively. (3) The total intrinsic value of stock options/SARs vested or expected to vest at March 31, 2017 and 2016 was $196.0 million and $121.1 million, respectively. At March 31, 2017 and 2016, the weighted average remaining contractual life was 3.8 years and 3.9 years, respectively. (4) The total intrinsic value of stock options/SARs exercisable at March 31, 2017 and 2016 was $155.5 million and $108.7 million, respectively. At March 31, 2017 and 2016, the weighted average remaining contractual life was 2.4 years and 2.7 years, respectively. At March 31, 2017, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $86.2 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.6 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 $18.6 million and $18.7 million for the three months ended March 31, 2017 and 2016. The following table sets forth restricted stock and restricted stock unit transactions for the three-month periods ended March 31, 2017 and 2016 (shares and units in thousands):   Three Months Ended   March 31, 2017   Three Months Ended   March 31, 2016   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 3,962   $ 79.63   4,908   $ 70.35 Granted 402   99.52   284   75.26 Released (1) (360 )   61.96   (353 )   53.88 Forfeited (82 )   82.83   (39 )   75.35 Outstanding at March 31 (2) 3,922   $ 83.22   4,800   $ 71.81 (1) The total intrinsic value of restricted stock and restricted stock units released for the three months ended March 31, 2017 and 2016 was $36.0 million and $24.7 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 March 31, 2017 and 2016 was $382.6 million and $348.4 million, respectively. At March 31, 2017, unrecognized compensation expense related to restricted stock and restricted stock units totaled $168.5 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.7 years. Performance Units and Performance Stock. EOG has granted performance units and/or performance stock (Performance Awards) to its executive officers annually since 2012. As more fully discussed in the grant agreements, the performance metric applicable to the Performance Awards 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 Awards granted could be outstanding. Subject to the termination provisions set forth in the grant agreements and the applicable performance multiple, the grants of Performance Awards will generally "cliff" vest five years from the date of grant. The fair value of the Performance Awards is estimated using a Monte Carlo simulation. At December 31, 2016, 545,290 Performance Awards were outstanding. Upon completion of the Performance Period for the Performance Awards granted in 2013, a performance multiple of 200% was applied to the 2013 grants resulting in an additional grant of 118,834 Performance Awards in February 2017. A total of 89,224 Performance Awards were released during the three months ended March 31, 2017, with a total intrinsic value of $9.0 million, based upon the closing price of EOG's common stock on the release date. Upon the application of the performance multiple at the completion of the remaining Performance Periods, a minimum of 299,540 and a maximum of 850,260 Performance Awards could be outstanding. There were 574,900 Performance Awards outstanding as of March 31, 2017. The total intrinsic value of Performance Awards outstanding at March 31, 2017 was $56.1 million. Stock-based compensation expense related to the Performance Award grants totaled $0.9 million and $0.5 million for the three month periods ended March 31, 2017 and 2016, respectively. At March 31, 2017, unrecognized compensation expense related to Performance Awards totaled $9.6 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.8 years.

Debt Disclosure [Abstract]
Long-Term Debt [Text Block]	Long-Term Debt EOG had no outstanding commercial paper borrowings or uncommitted credit facility borrowings at March 31, 2017, and did not utilize any such borrowings during the three months ended March 31, 2017. During the three months ended March 31, 2016, EOG utilized commercial paper, bearing market interest rates, for various corporate financing purposes. The average borrowings outstanding under the commercial paper program were $118 million during the three months ended March 31, 2016. The weighted average interest rate for commercial paper borrowings was 0.75% during the three months ended March 31, 2016. At March 31, 2017, $600 million aggregate principal amount of EOG's 5.875% Senior Notes due 2017 were classified as long-term debt based upon its intent and ability to ultimately replace such amount with other long-term debt. EOG currently has a $2.0 billion senior unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders. The Agreement has a scheduled maturity date of July 21, 2020, 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. Advances under the Agreement 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 Agreement) plus an applicable margin. At March 31, 2017, there were no borrowings or letters of credit outstanding under the Agreement. The Eurodollar rate and applicable base rate, had there been any amounts borrowed under the Agreement, would have been 1.98% and 4.00%, respectively.

Fair Value Disclosures [Abstract]
Fair Value Measurements [Text Block]	Fair Value Measurements As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2016 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, 2017 and December 31, 2016 (in millions):   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, 2017               Financial Assets:               Crude Oil Swaps $ —   $ 1   $ —   $ 1 Natural Gas Swaps —   1   —   1 Natural Gas Options/Collars —   4   —   4 Financial Liabilities:               Natural Gas Swaps $ —   $ 2   $ —   $ 2 Natural Gas Options/Collars —   5   —   5                 At December 31, 2016               Financial Assets:               Natural Gas Options/Collars $ —   $ 1   $ —   $ 1 Financial Liabilities:               Crude Oil Swaps $ —   $ 36   $ —   $ 36 Natural Gas Swaps —   4   —   4 Natural Gas Options/Collars —   22   —   22 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 $149 million were written down to their fair value of $11 million, resulting in pretax impairment charges of $138 million for the three months ended March 31, 2017. EOG utilized an accepted offer from a third-party purchaser as the basis for determining fair value for the $138 million of impairments of proved oil and gas properties and other property, plant and equipment.  Fair Value of Debt. At March 31, 2017 and December 31, 2016, EOG had outstanding $6,990 million aggregate principal amount of senior notes, which had estimated fair values of approximately $7,161 million and $7,190 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 [Text Block]	Risk Management Activities Commodity Price Risk. As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2016 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. On March 14, 2017, EOG executed the optional early termination provision granting EOG the right to terminate certain crude oil price swaps with notional volumes of 30,000 barrels per day (Bbld) at a weighted average price of $50.05 per barrel ($/Bbl) for the period March 1, 2017 through June 30, 2017. EOG received cash of $4.6 million for the early termination of these contracts. Presented below is a comprehensive summary of EOG's crude oil price swap contracts for the three months ended March 31, 2017, with notional volumes expressed in Bbld and prices expressed in $/Bbl. Crude Oil Price Swap Contracts     Volume (Bbld)   Weighted Average Price ($/Bbl) 2017         January 1, 2017 through February 28, 2017 (closed)   35,000   $ 50.04 March 1, 2017 through June 30, 2017 (closed)   30,000   50.05 On March 14, 2017, EOG entered into a crude oil price swap contract for the period March 1, 2017 through June 30, 2017, with notional volumes of 5,000 Bbld at a price of $48.81 per Bbl. This contract offsets the remaining crude oil price swap contract for the same time period with notional volumes of 5,000 Bbld at a price of $50.00 per Bbl. The net cash EOG will receive for settling these contracts is $0.7 million. The offsetting contracts were excluded from the above table. Presented below is a comprehensive summary of EOG's natural gas price swap contracts for the three months ended March 31, 2017, with notional volumes expressed in million British thermal units (MMBtu) per day (MMBtud) and prices expressed in dollars per MMBtu ($/MMBtu).

The call options require that EOG pay the difference between the call option strike price and either the average or last business day 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 call option strike price. In addition, EOG has purchased put options which establish a floor price for the sale of notional volumes of natural gas as specified in the put option contracts. The put options grant EOG the right to receive the difference between the put option strike price and the Henry Hub Index Price in the event the Henry Hub Index Price is below the put option strike price.

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 liability position at March 31, 2017 and December 31, 2016. EOG had no collateral posted and held no collateral at March 31, 2017 and December 31, 2016.

On October 4, 2016, EOG completed its previously announced mergers and related asset purchase transactions with Yates Petroleum Corporation (YPC), Abo Petroleum Corporation (ABO), MYCO Industries, Inc. (MYCO) and certain affiliated entities (collectively with YPC, ABO and MYCO, the Yates Entities). For a further discussion of these transactions, refer to Note 17 to the Consolidated Financial Statements in EOG's 2016 Annual Report. The assets of the Yates Entities include producing wells in addition to acreage in the Delaware Basin Core, the Powder River Basin, the Permian Basin Northwest Shelf and other Western basins. EOG accounted for the mergers with YPC, ABO and MYCO and the related asset purchase transactions as a business combination under the acquisition method with EOG as the acquirer. Under the acquisition method, the consideration transferred is allocated to the assets acquired and liabilities assumed based on their estimated fair values, with any excess of the consideration transferred over the estimated fair value of the identifiable net assets acquired recorded as goodwill. EOG did not record goodwill in connection with these transactions. There were no changes during the three months ended March 31, 2017, to the preliminary purchase price allocation. Certain data necessary to complete the purchase price allocation is preliminary, and includes, but is not limited to, the final valuations of oil and gas properties, the valuation of off-market transportation contracts and the calculation of deferred taxes based upon the underlying tax basis of assets acquired and liabilities assumed. EOG believes the estimates used are reasonable but are subject to change as additional information becomes available. Other.
