Summary of Significant Accounting Policies	9 Months Ended
	Sep. 30, 2016
Accounting Policies [Abstract]
Summary of Significant Accounting Policies [Text Block]	Summary of Significant Accounting Policies General. The 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 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, 2015, filed on February 25, 2016 (EOG's 2015 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 nine months ended September 30, 2016, are not necessarily indicative of the results to be expected for the full year. Effective January 1, 2016, EOG adopted the provisions of Accounting Standards Update (ASU) 2015-03, "Interest - Computation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (ASU 2015-03). ASU 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct reduction from the related debt liability rather than as an asset. In connection with the adoption of ASU 2015-03, EOG restated its December 31, 2015 Consolidated Balance Sheet to reclassify $4.8 million of unamortized debt issuance costs from "Other Assets" to "Long-Term Debt." Debt issuance costs related to EOG's senior unsecured credit facility remain classified as "Other Assets." Recently Issued Accounting Standards. In August 2016, the Financial Accounting Standards Board (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 March 2016, the FASB issued 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. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, and early application is permitted. EOG is evaluating ASU 2016-09 in order to determine what impact the new standard will have 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 November 2015, the FASB issued 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. ASU 2015-17 is effective for financial statements issued for interim and annual periods beginning after December 15, 2016, and early application is permitted. EOG does not intend to early-adopt ASU 2015-17 and does not expect the new standard to have a material impact on its consolidated financial statements and related disclosures. In July 2015, the FASB issued ASU 2015-11, "Accounting for Inventory" (ASU 2015-11), which requires entities to measure most inventory at lower of cost or net realizable value. ASU 2015-11 defines net realizable value as "the estimated selling prices in the ordinary course of business, less reasonably predictable cost of completion, disposal and transportation." ASU 2015-11 is effective prospectively for interim and annual periods beginning after December 15, 2016, and early application is permitted. EOG is reviewing the requirements of the new standard and does not believe that the adoption of ASU 2015-11 will have a material impact on its consolidated financial statements and related disclosures. In May 2014, the FASB issued ASU 2014-09, "Revenue From Contracts With Customers" (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 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 continues to analyze ASU 2014-09, as well as subsequent guidance which amends and clarifies certain aspects of ASU 2014-09, in order to determine what impact it will have 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 2015 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included on the 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   September 30,   Nine Months Ended   September 30,   2016   2015   2016   2015 Lease and Well $ 8.9   $ 10.3   $ 28.2   $ 32.9 Gathering and Processing Costs 0.4   0.4   1.0   1.0 Exploration Costs 4.1   6.0   15.6   19.3 General and Administrative 24.2   23.6   52.3   48.8 Total $ 37.6   $ 40.3   $ 97.1   $ 102.0 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 September 30, 2016, approximately 21.4 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 $18.8 million and $20.0 million during the three months ended September 30, 2016 and 2015, respectively, and $45.0 million and $43.3 million during the nine months ended September 30, 2016 and 2015, respectively. Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the nine-month periods ended September 30, 2016 and 2015 are as follows:   Stock Options/SARs   ESPP   Nine Months Ended   September 30,   Nine Months Ended   September 30,   2016   2015   2016   2015 Weighted Average Fair Value of Grants $ 25.77   $ 21.87   $ 19.28   $ 21.40 Expected Volatility 31.52 %   38.04 %   36.54 %   32.54 % Risk-Free Interest Rate 0.78 %   0.83 %   0.43 %   0.12 % Dividend Yield 0.76 %   0.85 %   0.82 %   0.72 % Expected Life 5.4 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 nine-month periods ended September 30, 2016 and 2015 (stock options and SARs in thousands):   Nine Months Ended   September 30, 2016   Nine Months Ended   September 30, 2015   Number of Stock Options/SARs   Weighted Average Grant Price   Number of Stock Options/SARs   Weighted Average Grant Price Outstanding at January 1 10,744   $ 67.98   10,493   $ 64.96 Granted 1,821   94.87   2,029   69.95 Exercised (1) (1,673 )   49.85   (1,291 )   47.25 Forfeited (241 )   85.77   (203 )   80.12 Outstanding at September 30 (2) 10,651   $ 75.02   11,028   $ 67.67 Vested or Expected to Vest (3) 10,300   $ 74.60   10,653   $ 67.22 Exercisable at September 30 (4) 6,302   $ 66.46   6,121   $ 57.34 (1) The total intrinsic value of stock options/SARs exercised for the nine months ended September 30, 2016 and 2015 was $58.7 million and $52.4 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 September 30, 2016 and 2015 was $240.8 million and $136.9 million, respectively. At September 30, 2016 and 2015, the weighted average remaining contractual life was 4.1 years and 4.4 years, respectively. (3) The total intrinsic value of stock options/SARs vested or expected to vest at September 30, 2016 and 2015 was $237.2 million and $135.7 million, respectively. At September 30, 2016 and 2015, the weighted average remaining contractual life was 4.0 years and 4.3 years, respectively. (4) The total intrinsic value of stock options/SARs exercisable at September 30, 2016 and 2015 was $196.3 million and $121.6 million, respectively. At September 30, 2016 and 2015, the weighted average remaining contractual life was 2.8 years and 3.1 years, respectively. At September 30, 2016, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $106.1 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 3.0 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 $13.1 million and $16.2 million for the three months ended September 30, 2016 and 2015, respectively, and $45.5 million and $53.9 million for the nine months ended September 30, 2016 and 2015, respectively. The following table sets forth restricted stock and restricted stock unit transactions for the nine-month periods ended September 30, 2016 and 2015 (shares and units in thousands):   Nine Months Ended   September 30, 2016   Nine Months Ended   September 30, 2015   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 4,908   $ 70.35   5,394   $ 64.39 Granted 833   87.76   1,036   77.90 Released (1) (1,392 )   53.15   (1,250 )   51.02 Forfeited (269 )   76.40   (152 )   74.83 Outstanding at September 30 (2) 4,080   $ 79.37   5,028   $ 70.18 (1) The total intrinsic value of restricted stock and restricted stock units released for the nine months ended September 30, 2016 and 2015 was $116.3 million and $102.5 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 September 30, 2016 and 2015 was $394.6 million and $366.0 million, respectively. At September 30, 2016, unrecognized compensation expense related to restricted stock and restricted stock units totaled $170.3 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.8 years. Performance Units and Performance Stock. EOG grants performance units and/or performance stock (Performance Awards) to its executive officers. As more fully discussed in the grant agreements, the performance metric applicable to these performance-based grants 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 "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, 2015, 405,000 Performance Awards were outstanding. Upon completion of the Performance Period for the Performance Awards granted in 2012, a performance multiple of 200% was applied to the 2012 grants resulting in an additional grant of 142,556 Performance Awards in February 2016. During the nine-month period ended September 30, 2016, a total of 71,805 Performance Awards were granted. A total of 134,016 Performance Awards were released during the nine months ended September 30, 2016, with a total intrinsic value of $9.7 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 151,096 and a maximum of 819,594 Performance Awards could be outstanding. There were 485,345 Performance Awards outstanding as of September 30, 2016. The total intrinsic value of Performance Awards outstanding at September 30, 2016 was $46.9 million. Weighted average fair values and valuation assumptions used to value performance unit and performance stock grants of Performance Awards during the nine-month periods ended September 30, 2016 and 2015 are as follows:   Nine Months Ended   September 30,   2016   2015 Weighted Average Fair Value of Grants $ 112.09   $ 80.64 Expected Volatility 32.01 %   29.35 % Risk-Free Interest Rate 0.89 %   1.07 % Expected volatility is based on the term-matched historical volatility over the simulated term, which is calculated as the time between the grant date and the end of the performance period. The risk-free interest rate is based on a 3.25 year zero-coupon risk-free interest rate derived from the Treasury Constant Maturities yield curve on the grant date. Stock-based compensation expense related to the Performance Award grants totaled $5.7 million and $4.1 million for the three month periods ended September 30, 2016 and 2015, respectively, and $6.6 million and $4.8 million for the nine month periods ended September 30, 2016 and 2015, respectively. At September 30, 2016, unrecognized compensation expense related to Performance Awards totaled $7.4 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 3.3 years.

Long-Term Debt	9 Months Ended
	Sep. 30, 2016
Debt Disclosure [Abstract]
Long-Term Debt [Text Block]	Long-Term Debt During the nine months ended September 30, 2016 and 2015, EOG utilized commercial paper borrowings bearing market interest rates, for various corporate financing purposes. At September 30, 2016 and 2015, EOG had zero and $30 million, respectively, of outstanding commercial paper borrowings and no uncommitted credit facility borrowings. The average borrowings outstanding under the commercial paper program were $155 million and $7 million during the nine months ended September 30, 2016 and 2015, respectively. The weighted average interest rates for commercial paper borrowings during the nine months ended September 30, 2016 and 2015 was 0.76% and 0.45%, respectively. At September 30, 2016, $600 million aggregate principal amount of EOG's 5.875% Senior Notes due 2017 were reclassified as long-term debt based upon its intent and ability to ultimately replace such amount with other long-term debt. On February 1, 2016, EOG repaid upon maturity the $400 million aggregate principal amount of its 2.500% Senior Notes due 2016 (2016 Notes). On January 14, 2016, EOG closed its sale of $750 million aggregate principal amount of its 4.15% Senior Notes due 2026 and $250 million aggregate principal amount of its 5.10% Senior Notes due 2036 (collectively, the Notes). Interest on the Notes is payable semi-annually in arrears on January 15 and July 15 of each year beginning on July 15, 2016. Net proceeds from the Notes offering totaled approximately $991 million and were used to repay the 2016 Notes when they matured on February 1, 2016, and for general corporate purposes, including repayment of outstanding commercial paper borrowings and funding of capital expenditures. 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 September 30, 2016, 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 1.53% and 3.50%, respectively.

Fair Value Measurements [Text Block]	Fair Value Measurements As more fully discussed in Note 13 to the Consolidated Financial Statements included in EOG's 2015 Annual Report, certain of EOG's financial and nonfinancial assets and liabilities are reported at fair value on the 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 September 30, 2016. There were no such amounts outstanding at December 31, 2015. Amounts shown 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 September 30, 2016               Financial Assets (1)               Crude Oil Collars $ —   $ 1   $ —   $ 1 Natural Gas Price Swaps/Options —   4   —   4 (1) At September 30, 2016, $2.2 million is included in "Current Assets - Assets From Price Risk Management Activities" and $2.5 million is included in "Other Assets" on the 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. 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 $625 million were written down to their fair value of $518 million, resulting in pretax impairment charges of $107 million for the nine months ended September 30, 2016. Included in the $107 million pretax impairment charges are $103 million of impairments of proved oil and gas properties and other property, plant and equipment for which EOG utilized an accepted offer from a third-party purchaser as the basis for determining fair value.  Fair Value of Debt. At September 30, 2016 and December 31, 2015, EOG had outstanding $6,990 million and $6,390 million, respectively, aggregate principal amount of senior notes, which had estimated fair values of approximately $7,395 million and $6,524 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 2015 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. Presented below is a comprehensive summary of EOG's crude oil price swap contracts for the nine months ended September 30, 2016, with notional volumes expressed in barrels per day (Bbld) and prices expressed in dollars per barrel ($/Bbl). Crude Oil Price Swap Contracts     Volume (Bbld)   Weighted Average Price ($/Bbl) 2016         April 12, 2016 through April 30, 2016 (closed)   90,000   $ 42.30 May 1, 2016 through June 30, 2016 (closed)   128,000   42.56 EOG has entered into crude oil collar contracts, which establish ceiling and floor prices for the sale of notional volumes of crude oil as specified in the collar contracts. The collars require that EOG pay the difference between the ceiling price and the average NYMEX West Texas Intermediate crude oil price for the contract month (Index Price) in the event the Index Price is above the ceiling price. The collars grant EOG the right to receive the difference between the floor price and the Index Price in the event the Index Price is below the floor price. Presented below is a comprehensive summary of EOG's crude oil collar contracts for the nine months ended September 30, 2016, with notional volumes expressed in Bbld and prices expressed in $/Bbl.

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. Presented below is a comprehensive summary of EOG's natural gas call and put option contracts for the nine months ended September 30, 2016, with notional volumes expressed in MMBtud and prices expressed in $/MMBtu.

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. There were no derivative instruments in a net liability position at September 30, 2016. EOG had no collateral posted and held no collateral at September 30, 2016 and December 31, 2015.

Divestitures [Text Block]	Divestitures During the first nine months of 2016, EOG received proceeds of approximately $458 million primarily from sales of producing properties and acreage in Texas, the Rocky Mountain area and Oklahoma. Additionally, in the third quarter of 2016, EOG signed purchase and sale agreements for the sale of certain properties in the United States. At September 30, 2016, the book value of these proved oil and gas properties and other property, plant and equipment held for sale and the related asset retirement obligations were $55 million and $14 million, respectively. During the first nine months of 2015, EOG received proceeds of approximately $144 million primarily from sales of gathering and processing assets. During the third quarter of 2016, EOG completed the sale of all its Argentina assets.

Subsequent Events [Abstract]
Subsequent Event [Text Block]	Subsequent Event 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). Subject to the terms of the agreements, EOG issued to the shareholders of YPC, ABO and MYCO and to certain of the sellers under the related asset purchase transactions an aggregate of approximately 25 million shares of EOG common stock and paid to certain of the sellers under the asset purchase transactions an aggregate of approximately $16 million in cash for total consideration transferred of $2.4 billion. In addition, under the terms of the transactions, EOG repaid approximately $164 million of debt owed by the Yates Entities, which was offset by approximately $64 million of cash of the Yates Entities. The assets of the Yates Entities include producing wells in addition to acreage in the Delaware Basin Core, the Delaware Basin Shelf, the Powder River Basin and other Western basins. The financial results of YPC, ABO and MYCO will be included in EOG's consolidated financial statements beginning October 4, 2016. EOG will account for the mergers with YPC, ABO and MYCO and 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. Acquisition-related costs are expensed as incurred. Due to the limited time elapsed since the acquisition date, the initial accounting for the business combination is incomplete. As a result, EOG is unable to provide amounts recognized as of October 4, 2016, the acquisition date, for major classes of assets acquired and liabilities assumed from these transactions. This information will be included in EOG's Annual Report on Form 10-K for the year ended December 31, 2016.
