Summary of Significant Accounting Policies [Text Block]	'
	1.    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, 2013, filed on February 24, 2014 (EOG's 2013 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, 2014, are not necessarily indicative of the results to be expected for the full year.
	On February 24, 2014, EOG's Board of Directors (Board) approved a two-for-one stock split in the form of a stock dividend, payable to stockholders of record as of March 17, 2014, and paid on March 31, 2014. All share and per share amounts in the financial statements and these notes have been restated to reflect the two-for-one stock split.
	Recently Issued Accounting Standards. In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2014-09 (ASU 2014-09), "Revenue From Contracts With Customers," 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 will be effective for interim and annual reporting periods beginning after December 15, 2016. Early application is not permitted. EOG is analyzing the requirements of ASU 2014-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

	2.    Stock-Based Compensation
	As more fully discussed in Note 6 to the Consolidated Financial Statements included in EOG's 2013 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 June 30,								Six Months Ended June 30,
		2014				2013				2014				2013
	Lease and Well	$	9.1			$	8.4			$	20.7			$	18.2
	Gathering and Processing Costs	0.2				0.3				0.5				0.6
	Exploration Costs	5.6				6.4				13.5				13.9
	General and Administrative	14.6				12.2				30.4				25
	Total	$	29.5			$	27.3			$	65.1			$	57.7
	The Amended and Restated EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan (2008 Plan) provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock, restricted stock units, performance units, performance stock and other stock-based awards. At June 30, 2014, approximately 32.3 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to the 2008 Plan from either 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 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 $11.7 million and $10.4 million during the three months ended June 30, 2014 and 2013, respectively, and $23.7 million and $20.8 million during the six months ended June 30, 2014 and 2013, 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, 2014 and 2013 are as follows:
		Stock Options/SARs								ESPP
		Six Months Ended June 30,								Six Months Ended June 30,
		2014				2013				2014				2013
	Weighted Average Fair Value of Grants	$	27.68			$	19.33			$	18.3			$	14.4
	Expected Volatility	35.15		%		35.82		%		25.83		%		29.95		%
	Risk-Free Interest Rate	0.86		%		0.48		%		0.09		%		0.12		%
	Dividend Yield	0.5		%		0.6		%		0.4		%		0.6		%
	Expected Life	5.2 years				5.5 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, 2014 and 2013 (stock options and SARs in thousands):
		Six Months Ended June 30, 2014							Six Months Ended June 30, 2013

	Exercisable at June 30 (4)	3,898			$	44.71			4,510			$	39.99
	-1	The total intrinsic value of stock options/SARs exercised for the six months ended June 30, 2014 and 2013 was $52.5 million and $62.1 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 June 30, 2014 and 2013 was $576.8 million and $219.5 million, respectively. At June 30, 2014 and 2013, the weighted average remaining contractual life was 4.2 years and 4.1 years, respectively.
	-3	The total intrinsic value of stock options/SARs vested or expected to vest at June 30, 2014 and 2013 was $553.8 million and $211.7 million, respectively. At June 30, 2014 and 2013, the weighted average remaining contractual life was 4.2 years and 4.1 years, respectively.
	-4	The total intrinsic value of stock options/SARs exercisable at June 30, 2014 and 2013 was $281.3 million and $116.7 million, respectively. At June 30, 2014 and 2013, the weighted average remaining contractual life was 2.8 years and 2.6 years, respectively.
	At June 30, 2014, unrecognized compensation expense related to non-vested stock option, SAR and ESPP grants totaled $83.5 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.2 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 $16.8 million and $16.6 million for the three months ended June 30, 2014 and 2013, respectively, and $39.5 million and $36.3 million for the six months ended June 30, 2014 and 2013, respectively.
	The following table sets forth restricted stock and restricted stock unit transactions for the six-month periods ended June 30, 2014 and 2013 (shares and units in thousands):

	Outstanding at June 30 (2)	5,673			$	57.06			7,472			$	45.56
	-1	The total intrinsic value of restricted stock and restricted stock units released for the six months ended June 30, 2014 and 2013 was $207.0 million and $35.4 million, respectively. The intrinsic value is based upon the closing price of EOG's common stock on the date restricted stock and restricted stock units are released.
	-2	The total intrinsic value of restricted stock and restricted stock units outstanding at June 30, 2014 and 2013 was $662.9 million and $491.9 million, respectively.
	At June 30, 2014, unrecognized compensation expense related to restricted stock and restricted stock units totaled $148.5 million. Such unrecognized expense will be amortized on a straight-line basis over a weighted average period of 2.1 years.
	Performance Units and Performance Stock. EOG grants performance units and/or performance stock to its executive officers. The fair value of the performance units and performance stock is estimated using a Monte Carlo simulation. Stock-based compensation expense related to performance unit and performance stock grants totaled $1.0 million and $0.3 million for the three months ended June 30, 2014 and 2013, and $1.9 million and $0.6 million for the six months ended June 30, 2014 and 2013.

	Long-Term Debt. During the six months ended June 30, 2014 and 2013, EOG utilized commercial paper and short-term borrowings under uncommitted credit facilities, bearing market interest rates, for various corporate financing purposes. EOG had no outstanding borrowings from commercial paper or uncommitted credit facilities at June 30, 2014. The average borrowings outstanding under the commercial paper program were $18 million and $21 million during the six months ended June 30, 2014 and 2013, respectively. The average borrowings outstanding under the uncommitted credit facilities were $0.2 million and zero during the six months ended June 30, 2014 and 2013, respectively. The weighted average interest rates for commercial paper borrowings during the six months ended June 30, 2014 and 2013 were 0.25% and 0.31%, respectively, and 0.70% for uncommitted credit facility borrowings during the six months ended June 30, 2014.
	On March 21, 2014, EOG closed its sale of the $500 million aggregate principal amount of its 2.45% Senior Notes due 2020 (Notes). Interest on the Notes is payable semi-annually in arrears on April 1 and October 1 of each year, beginning October 1, 2014. Net proceeds from the Notes offering of approximately $496 million were used for general corporate purposes.
	On March 17, 2014, EOG repaid upon maturity the $150 million aggregate principal amount of its 4.75% Subsidiary Debt due 2014 (Subsidiary Debt) and settled the foreign currency swap entered into contemporaneously with the issuance of the Subsidiary Debt for $32 million.
	On February 3, 2014, EOG repaid upon maturity the $350 million aggregate principal amount of its Floating Rate Senior Notes due 2014 (Floating Rate Notes). On the same date, EOG settled the interest rate swap entered into contemporaneously with the issuance of the Floating Rate Notes for $0.8 million.
	EOG currently has a $2.0 billion unsecured Revolving Credit Agreement (Agreement) with domestic and foreign lenders. The Agreement matures on October 11, 2016 and includes an option for EOG to extend, on up to two occasions, the term for successive one-year periods, subject to, among certain other terms and conditions, the consent of the banks holding greater than 50% of the commitments then outstanding under the Agreement. At June 30, 2014, there were no borrowings or letters of credit outstanding under the Agreement. Advances under the Agreement accrue interest based, at EOG's option, on either the London InterBank Offered Rate (LIBOR) plus an applicable margin (Eurodollar rate), or the base rate (as defined in the Agreement) plus an applicable margin. At June 30, 2014, the Eurodollar rate and applicable base rate, had there been any amounts borrowed under the Agreement, would have been 1.03% and 3.25%, respectively.
	Restricted Cash. In order to comply with the Canadian Alberta Energy Regulator's requirements to post financial security for well abandonment obligations, EOG Resources Canada Inc. (EOGRC) established a 160 million Canadian dollar letter of credit facility (subsequently increased to 190 million Canadian dollars) which matures on May 29, 2018 with Royal Bank of Canada (RBC) as the lender. The letter of credit facility requires EOGRC to deposit cash, in an amount equal to all outstanding letters of credit under such facility, in a cash collateral account at RBC. At June 30, 2014, the balance in this account was 170 million Canadian dollars (159 million United States dollars).
	Common Stock. On February 24, 2014, the Board increased the quarterly cash dividend on the common stock from the previous $0.09375 per share to $0.125 per share, effective beginning with the dividend paid on April 30, 2014 to stockholders of record as of April 16, 2014. On August 5, 2014, the Board increased the quarterly cash dividend on the common stock from the previous $0.125 per share to $0.1675 per share, effective beginning with the dividend to be paid on October 31, 2014, to stockholders of record as of October 17, 2014.

	As more fully discussed in Note 12 to the Consolidated Financial Statements included in EOG's 2013 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 June 30, 2014 and December 31, 2013 (in millions):

	Crude Oil Options/Swaptions	—		110		—		110
	Foreign Currency Rate Swap	—		40		—		40
	Interest Rate Swap	—		1		—		1
	The estimated fair value of crude oil and natural gas derivative contracts (including options/swaptions) and the interest rate swap contract was based upon forward commodity price and interest rate curves based on quoted market prices. The estimated fair value of the foreign currency rate swap was based upon forward currency rates. 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 with a carrying amount of $95 million were written down to their fair value of $20 million, resulting in pretax impairment charges of $75 million for the six months ended June 30, 2014. Included in the $75 million pretax impairment charges are $56 million of impairments of proved oil and gas properties for which EOG utilized an accepted offer from a third-party purchaser as the basis for determining fair value. Significant Level 3 inputs associated with the calculation of discounted cash flows used in the impairment analysis include EOG's estimate of future crude oil and natural gas prices, production costs, development expenditures, anticipated production of proved reserves, appropriate risk-adjusted discount rates and other relevant data.
	Fair Value of Debt. At both June 30, 2014 and December 31, 2013, EOG had outstanding $5,890 million aggregate principal amount of debt, which had estimated fair values of approximately $6,323 million and $6,222 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 [Text Block]	'
	12.    Risk Management Activities
	Commodity Price Risk. As more fully discussed in Note 11 to the Consolidated Financial Statements included in EOG's 2013 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. In addition to financial transactions, from time to time, EOG is a party to various physical commodity contracts for the sale of hydrocarbons that cover varying periods of time and have varying pricing provisions. These physical commodity contracts qualify for the normal purchases and normal sales exception and, therefore, are not subject to hedge accounting or mark-to-market accounting. The financial impact of physical commodity contracts is included in revenues at the time of settlement, which in turn affects average realized hydrocarbon prices.
	Commodity Derivative Contracts. Presented below is a comprehensive summary of EOG's crude oil derivative contracts at June 30, 2014, with notional volumes expressed in barrels per day (Bbld) and prices expressed in dollars per barrel ($/Bbl).

	-1	EOG has entered into crude oil derivative contracts which give counterparties the option to extend certain current derivative contracts for additional six-month periods. Options covering a notional volume of 69,000 Bbld are exercisable on or about December 31, 2014. If the counterparties exercise all such options, the notional volume of EOG's existing crude oil derivative contracts will increase by 69,000 Bbld at an average price of $95.20 per barrel for each month during the period January 1, 2015 through June 30, 2015.
	Presented below is a comprehensive summary of EOG's natural gas derivative contracts at June 30, 2014, with notional volumes expressed in million British thermal units (MMBtu) per day (MMBtud) and prices expressed in dollars per MMBtu ($/MMBtu).

	-1	EOG has entered into natural gas derivative contracts which give counterparties the option of entering into derivative contracts at future dates. All such options are exercisable monthly up until the settlement date of each monthly contract. If the counterparties exercise all such options, the notional volume of EOG's existing natural gas derivative contracts will increase by 480,000 MMBtud at an average price of $4.63 per MMBtu for each month during the period August 1, 2014 through December 31, 2014.
	-2	EOG has entered into natural gas derivative contracts which give counterparties the option of entering into derivative contracts at future dates. All such options are exercisable monthly up until the settlement date of each monthly contract. If the counterparties exercise all such options, the notional volume of EOG's existing natural gas derivative contracts will increase by 175,000 MMBtud at an average price of $4.51 per MMBtu for each month during the period January 1, 2015 through December 31, 2015.
	Foreign Currency Exchange Rate Derivative. EOG was party to a foreign currency aggregate swap with multiple banks to eliminate any exchange rate impacts that may have resulted from the Subsidiary Debt issued by one of EOG's Canadian subsidiaries. The foreign currency swap expired and was settled contemporaneously with the repayment upon maturity of the Subsidiary Debt on March 17, 2014 (see Note 10).
	Interest Rate Derivative. EOG was a party to an interest rate swap with a counterparty bank. The interest rate swap was entered into in order to mitigate EOG's exposure to volatility in interest rates related to its Floating Rate Notes. The interest rate swap expired and was settled contemporaneously with the repayment upon maturity of the Floating Rate Notes on February 3, 2014 (see Note 10).
	The following table sets forth the amounts and classification of EOG's outstanding derivative financial instruments at June 30, 2014 and December 31, 2013. Certain amounts may be presented on a net basis on the consolidated financial statements when such amounts are with the same counterparty and subject to a master netting arrangement (in millions):

	-2	The noncurrent portion of Assets from Price Risk Management Activities consists of gross assets of $11 million, partially offset by gross liabilities of $6 million at June 30, 2014.
	-3	The current portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $352 million, partially offset by gross assets of $14 million at June 30, 2014, and gross liabilities of $137 million, partially offset by gross assets of $10 million at December 31, 2013.
	-4	The noncurrent portion of Liabilities from Price Risk Management Activities consists of gross liabilities of $6 million, offset by gross assets of $6 million at June 30, 2014.
	Credit Risk. Notional contract amounts are used to express the magnitude of commodity price, foreign currency and interest rate swap agreements. 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 outstanding 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 June 30, 2014 and December 31, 2013. EOG held no collateral at June 30, 2014 and December 31, 2013. EOG had collateral of $79 million posted at June 30, 2014 and no collateral posted at December 31, 2013.
