Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	1.     Summary of Significant Accounting Policies
	The accompanying unaudited financial statements and notes of Devon Energy Corporation (“Devon”) have been prepared pursuant to the rules and regulations of the United States Securities and Exchange Commission. Pursuant to such rules and regulations, certain disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted. The accompanying financial statements and notes should be read in conjunction with the financial statements and notes included in Devon's 2013 Annual Report on Form 10-K.
	The accompanying unaudited interim financial statements furnished in this report reflect all adjustments that are, in the opinion of management, necessary for a fair statement of Devon's results of operations and cash flows for the three-month periods ended March 31, 2014 and 2013 and Devon's financial position as of March 31, 2014.
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Devon and entities in which it holds a controlling interest. All intercompany transactions have been eliminated. Undivided interests in oil and natural gas exploration and production joint ventures are consolidated on a proportionate basis. Investments in non-controlled entities, over which Devon has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method. In applying the equity method of accounting, the investments are initially recognized at cost, and subsequently adjusted for Devon’s proportionate share of earnings, losses, and distributions. Investments accounted for using the equity method and cost method are reported as a component of other long-term assets.
	As discussed more fully in Note 2, on March 7, 2014, Devon completed a business combination whereby Devon controls both EnLink Midstream Partners, LP (the “Partnership”) and its general partner entity, EnLink Midstream, LLC (“EnLink”). Devon controls both the Partnership’s and EnLink’s operations; therefore, the Partnership and EnLink’s accounts are included in Devon’s accompanying consolidated financial statements subsequent to the completion of the transaction. The portions of the Partnership and EnLink’s net earnings and stockholders’ equity not attributable to Devon’s controlling interest are shown separately as noncontrolling interests in the accompanying consolidated comprehensive statements of earnings and consolidated balance sheets.
	Intangible Assets
	EnLink’s long-term assets include intangible assets,  consisting of customer relationships. These assets are amortized on a straight-line basis over the expected periods of benefits, which range from fifteen to twenty years.

	2.    Acquisitions and Divestitures
	Formation of EnLink Midstream, LLC and EnLink Midstream Partners, LP
	On March 7, 2014, Devon, Crosstex Energy, Inc. and Crosstex Energy, LP (together with Crosstex Energy, Inc., “Crosstex”) completed a business combination to combine substantially all of Devon’s U.S. midstream assets with Crosstex’s assets to form a new midstream business. The new business consists of the Partnership and EnLink, a master limited partnership and a general partner entity, respectively, which are both publicly traded entities.
	In exchange for a controlling interest in both EnLink and the Partnership, Devon contributed its equity interest in a newly formed Devon subsidiary EnLink Midstream Holdings, LP (“EnLink Holdings”) and $100 million in cash. EnLink Holdings owns Devon’s midstream assets in the Barnett Shale in north Texas and the Cana and Arkoma Woodford Shales in Oklahoma, as well as Devon’s economic interest in Gulf Coast Fractionators in Mt. Belvieu, Texas. The Partnership and EnLink each own 50 percent of EnLink Holdings.
	The ownership of EnLink is approximately:
		•		70% - Devon
		•		30% - Public unitholders
	The ownership of the Partnership is approximately:
		•		52% - Devon
		•		41% - Public unitholders
		•		7% - EnLink
	This business combination was accounted for using the acquisition method of accounting. Under the acquisition method of accounting, EnLink Holdings was the accounting acquirer because its parent company, Devon, obtained control of EnLink and the Partnership as a result of the business combination. Consequently, EnLink Holdings’ assets and liabilities retained their carrying values. Additionally, the Crosstex assets acquired and liabilities assumed by the Partnership and EnLink in the business combination, as well as EnLink’s noncontrolling interest in the Partnership, were recorded at their fair values which were measured as of the acquisition date, March 7, 2014. The excess of the purchase price over the estimated fair values of Crosstex’s net assets acquired was recorded as goodwill. The purchase price allocation has been prepared on a preliminary basis pending receipt of a final valuation report and is subject to material change.
	The following table summarizes the preliminary estimate of the purchase price and its allocation to the assets acquired and liabilities assumed (in millions, except unit price).
	Crosstex Energy, Inc. outstanding common shares:
	Held by public shareholders			48.0
	Restricted shares			0.4
	Total subject to conversion			48.4
	Exchange ratio			1.0	x

	Crosstex Energy, Inc. common share price (1)		$	37.60
	Crosstex Energy, Inc. consideration		$	1,823
	Partnership outstanding units:
	Common units held by public unitholders			75.1
	Preferred units held by third party (2)			17.1
	Restricted units			0.4
	Total			92.6
	Partnership common unit price (3)		$	30.51
	Partnership common units value		$	2,825
	Partnership outstanding unit options value		$	4
	Total fair value of noncontrolling interests (3)		$	2,829
	Total consideration and fair value of noncontrolling interests		$	4,652
	__________________________
	(1) The final purchase price is based on the fair value of Crosstex Energy Inc.’s common shares as of the closing date, March 7, 2014.
	(2) The Partnership converted the preferred units to common units in February 2014.
	(3) The final purchase price is based on the fair value of the Partnership’s common shares as of the closing date, March 7, 2014.
	The preliminary allocation of the purchase price is as follows (in millions):
	Current assets		$	438
	Property, plant and equipment, net			2,412
	Intangible assets			427
	Equity investment			222
	Goodwill (1)			3,420
	Other long term assets			1
	Current liabilities			514
	Long-term debt			1,454
	Deferred income taxes			199
	Other long-term liabilities			101
	Total consideration and fair value of noncontrolling interests		$	4,652
	__________________________
	(1)  Goodwill was the excess of the consideration transferred over the net assets recognized and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Goodwill is not amortized and is not deductible for tax purposes.
	GeoSouthern Energy Acquisition
	On November 20, 2013, Devon entered into a Purchase and Sale Agreement with GeoSouthern Energy Corporation (“GeoSouthern”) and a wholly owned subsidiary of GeoSouthern to acquire GeoSouthern’s interests in certain affiliates (the “Acquired Companies”) that own certain oil and gas properties, leasehold mineral interest and related assets located in the Eagle Ford Shale. On February 28, 2014, the GeoSouthern acquisition closed and GeoSouthern transferred the Acquired Companies to Devon in exchange for the aggregate purchase price of approximately $6.0 billion. Devon funded the acquisition price with cash on hand and debt financing. In connection with the GeoSouthern acquisition, Devon acquired approximately 82,000 net acres located in DeWitt and Lavaca counties in south Texas. The transaction was accounted for using the acquisition method, which requires, among other things, that assets acquired and liabilities assumed be recognized at their fair values as of the acquisition date. The purchase price allocation has been prepared on a preliminary basis and is subject to material change. The following table summarizes the preliminary allocation of the purchase price to the assets acquired and liabilities assumed in the transaction (in millions).
	Cash and cash equivalents		$	95
	Other current assets			252

Derivative Financial Instruments [Abstract]	'
Derivative Financial Instruments	'
	3.     Derivative Financial Instruments
	Objectives and Strategies
	Devon periodically enters into derivative financial instruments with respect to a portion of its oil, gas and NGL production. These instruments are used to manage the inherent uncertainty of future revenues due to commodity price volatility and typically include financial price swaps, basis swaps, costless price collars and call options. Devon periodically enters into interest rate swaps to manage its exposure to interest rate volatility. Devon periodically enters into foreign exchange forward contracts to manage its exposure to fluctuations in exchange rates. Additionally, EnLink manages its exposure to fluctuations in commodity prices by hedging the impact of market fluctuations.
	Devon does not intend to hold or issue derivative financial instruments for speculative trading purposes and has elected not to designate any of its derivative instruments for hedge accounting treatment.
	Counterparty Credit Risk
	By using derivative financial instruments, Devon is exposed to credit risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. To mitigate this risk, the hedging instruments are placed with a number of counterparties whom Devon believes are acceptable credit risks. It is Devon's policy to enter into derivative contracts only with investment grade rated counterparties deemed by management to be competent and competitive market makers. Additionally, Devon's derivative contracts contain provisions that provide for collateral payments, depending on levels of exposure and the credit rating of the counterparty. As of March 31, 2014, Devon did not hold any cash collateral from its counterparties.
	Commodity Derivatives
	As of March 31, 2014, Devon had the following open oil derivative positions. The first table presents Devon’s oil derivatives that settle against the average of the prompt month NYMEX West Texas Intermediate futures price.

	In the first quarter of 2013, Devon recognized asset impairments related to its oil and gas property and equipment as presented below.
		Three Months Ended March 31, 2013
		Gross		Net of Taxes
		(In millions)
	U.S. oil and gas assets	$	1,110	$	707
	Canada oil and gas assets		803		601
	Total asset impairments	$	1,913	$	1,308
	Oil and Gas Impairments
	Under the full-cost method of accounting, capitalized costs of oil and gas properties, net of accumulated DD&A and deferred income taxes, may not exceed the full-cost “ceiling” at the end of each quarter. The ceiling is calculated separately for each country and is based on the present value of estimated future net cash flows from proved oil and gas reserves, discounted at 10 percent per annum, net of related tax effects. Estimated future net cash flows are calculated using end-of-period costs and an unweighted arithmetic average of commodity prices in effect on the first day of each of the previous 12 months.
	The oil and gas impairments resulted primarily from declines in the U.S. and Canada full-cost ceilings. The lower ceiling values resulted primarily from decreases in the 12-month average trailing prices for oil, bitumen and NGLs, which reduced proved reserve values.

	In the first quarter of 2014, Devon recognized $37 million of estimated employee related costs associated with its Canadian non-core asset divestitures. Approximately $14 million of the employee related costs resulted from accelerated vesting of share-based grants, which are non-cash charges.
	Office Consolidation
	In October 2012, Devon announced plans to consolidate its U.S. personnel into a single operations group centrally located at the company’s headquarters in Oklahoma City. As of December 31, 2013, Devon had completed this initiative and incurred $134 million of restructuring costs associated with the office consolidation.

Included in the assets Devon contributed to EnLink Holdings was $402 million of goodwill, which is in the table below. The additional EnLink goodwill of $3.4 billion represents the goodwill recognized on the EnLink transaction described in Note 2. The decrease in Devon’s Canadian goodwill was primarily due to changes in the exchange rate between the United States dollar and the Canadian dollar, as well as goodwill removed in conjunction with minor asset divestitures.

	_____________________
		-1		March 31, 2014 short-term debt consists of $2.0 billion term loan drawn in conjunction with the GeoSouthern acquisition,  $1.6 billion of commercial paper and the EnLink $189 million senior note along with the associated $9 million premium, which was redeemed on April 18, 2014. December 31, 2013 short-term debt consists of $2.25 billion of senior notes issued in conjunction with the GeoSouthern acquisition, $1.3 billion of commercial paper and $500 million of senior notes due January 15, 2014.
	Commercial Paper
	As of March 31, 2014, Devon had $1.6 billion of outstanding commercial paper at an average rate of 0.23 percent.
	Credit Lines
	Devon has a $3.0 billion syndicated, unsecured revolving line of credit (the "Senior Credit Facility"). As of March 31, 2014, there were no borrowings under the Senior Credit Facility. The Senior Credit Facility contains only one material financial covenant. This covenant requires Devon’s ratio of total funded debt to total capitalization, as defined in the credit agreement, to be no greater than 65 percent. As of March 31, 2014, Devon was in compliance with this covenant with a debt-to-capitalization ratio of 28.3 percent.
	Term Loans
	In December 2013, in conjunction with the GeoSouthern acquisition, Devon entered into a term loan agreement with a group of major financial institutions. In February 2014, Devon drew $2.0 billion of term loans to finance, in part, the GeoSouthern acquisition and to pay transaction costs. Under the term loan agreement, $1.0 billion of the term loans have a maturity of three years, and the remaining $1.0 billion have a maturity of five years (the “5-Year Loans”). The 5-Year Loans will provide for the partial amortization of principal during the last two years that they are outstanding. Loans outstanding under the term loan agreement, at Devon’s election, bear interest at various fixed rate options for periods up to six months. Such rates are generally less than the prime rate. However, Devon may elect to borrow at the prime rate.
	Devon intends to repay the $2.0 billion term loans in the second quarter of 2014 using Canadian divestiture proceeds that will be repatriated to the U.S. Accordingly, amounts outstanding under the term loans have been classified as short-term debt in the consolidated balance sheet as of March 31, 2014.
	EnLink Debt
	Senior Notes
	The table below summarizes the fair value of EnLink’s debt as of March 7, 2014, the formation date of EnLink. The premiums are being amortized using the effective interest method. EnLink’s debt is non-recourse to Devon.
		March 7, 2014 Fair Value			Effective
		of Debt			Rate of Debt
		(In millions)
	8.875% due February 15, 2018 (principal of $725 million)	$	760		7.70%
	7.125% due June 1, 2022 (principal of $197 million)		226		5.30%
	Credit facilities		468
	Total long-term debt	$	1,454
	Credit Facilities
	The Partnership has a $1.0 billion unsecured revolving credit facility, which includes a $500 million letter of credit subfacility. As of March 31, 2014, there were no borrowings under the $1.0 billion credit facility.
	The $1.0 billion credit facility will mature on the fifth anniversary of the initial funding date, which was March 7, 2014, unless EnLink requests, and the requisite lenders agree, to extend it pursuant to its terms. The credit facility contains certain financial, operational and legal covenants.  Among other things, these covenants include maintaining a ratio of consolidated indebtedness to EnLink’s consolidated EBITDA (as defined in the credit facility, which definition includes projected EnLink EBITDA from certain capital expansion projects) of no more than 5.0 to 1.0. If EnLink consummates one or more acquisitions in which the aggregate purchase price is $50 million or more, the maximum allowed ratio of consolidated indebtedness to EnLink’s consolidated EBITDA will increase to 5.5 to 1.0 for the quarter of the acquisition and the three following quarters.
	EnLink also has a $250 million revolving credit facility, which includes a $125 million letter of credit subfacility, as well as an additional credit agreement in association with E2 Energy Services LLC under which EnLink can borrow up to $20 million. As of March 31, 2014, EnLink’s outstanding borrowings under the $250 million credit facility was $103 million and $15 million in association with the E2 Energy Services LLC credit agreement.
	The $250 million credit facility will mature on March 7, 2019. The credit facility contains certain financial, operational and legal covenants. The financial covenants will be tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter, and include (i) maintaining a maximum consolidated leverage ratio (as defined in the credit facility, but generally computed as the ratio of consolidated funded indebtedness to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) of 4.00 to 1.00, provided that the maximum consolidated leverage ratio is 4.50 to 1.00 during an acquisition period (as defined in the credit facility) and (ii) maintaining a minimum consolidated interest coverage ratio (as defined in the credit facility, but generally computed as the ratio of consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges to consolidated interest charges) of 2.50 to 1.00 at all times prior to the occurrence of an investment grade event (as defined in the credit facility).

	17.    Commitments and Contingencies
	Devon is party to various legal actions arising in the normal course of business. Matters that are probable of unfavorable outcome to Devon and which can be reasonably estimated are accrued. Such accruals are based on information known about the matters, Devon's estimates of the outcomes of such matters and its experience in contesting, litigating and settling similar matters. None of the actions are believed by management to involve future amounts that would be material to Devon's financial position or results of operations after consideration of recorded accruals. Actual amounts could differ materially from management's estimates.
	Royalty Matters
	Numerous oil and natural gas producers and related parties, including Devon, have been named in various lawsuits alleging royalty underpayments. The suits allege that the producers and related parties used below-market prices, made improper deductions, used improper measurement techniques and entered into gas purchase and processing arrangements with affiliates that resulted in underpayment of royalties in connection with oil, natural gas and NGLs produced and sold. Devon’s largest exposure for such matters relates to royalties associated with Devon’s operations in New Mexico. Devon expects to mediate or go to trial before the end of 2014 as ordered by the court in the first quarter of 2014. Devon does not currently believe that it is subject to material exposure with respect to such royalty matters.
	Environmental Matters
	Devon is subject to certain laws and regulations relating to environmental remediation activities associated with past operations, such as the Comprehensive Environmental Response, Compensation, and Liability Act and similar state statutes. In response to liabilities associated with these activities, loss accruals primarily consist of estimated uninsured remediation costs. Devon's monetary exposure for environmental matters is not expected to be material.
	Other Matters
	Devon is involved in other various routine legal proceedings incidental to its business. However, to Devon's knowledge, there were no other material pending legal proceedings to which Devon is a party or to which any of its property is subject.

	The following methods and assumptions were used to estimate the fair values in the tables above.
	Level 1 Fair Value Measurements
	Cash equivalents —  Amounts consist primarily of U.S. and Canadian treasury securities and money market investments. The fair value approximates the carrying value.
	Level 2 Fair Value Measurements
	Cash equivalents —  Amounts consist primarily of Canadian agency and provincial securities and commercial paper investments. The fair value approximates the carrying value.
	Commodity, interest rate and foreign currency derivatives — The fair values of commodity, interest rate and foreign currency derivatives are estimated using internal discounted cash flow calculations based upon forward curves and data obtained from independent third parties for contracts with similar terms or data obtained from counterparties to the agreements.
	Debt — Devon's debt instruments do not actively trade in an established market. The fair values of its debt are estimated based on rates available for debt with similar terms and maturity. The fair value of Devon’s commercial paper and EnLink’s credit facility is the carrying value.
	Obligations under capital leases —  The fair value of obligations under capital leases was calculated using inputs from third-party banks.
	Level 3 Fair Value Measurements
	Long-term investments — Devon’s long-term investments as of December 31, 2013 consisted entirely of auction rate securities. In the first quarter of 2014, Devon redeemed all these securities for approximately $57 million, or $5 million below their carrying value.

Segment Information [Abstract]	'
Segment Information	'
	19.    Segment Information
	Devon manages its operations through distinct operating segments, which are defined primarily by geographic areas. For financial reporting purposes, Devon aggregates its U.S. operating segments into one reporting segment due to the similar nature of the businesses. However, Devon's Canadian operating segment is reported as a separate reporting segment primarily due to the significant differences between the U.S. and Canadian regulatory environments. Devon’s U.S. and Canadian segments are all primarily engaged in oil and gas exploration and production activities.
	With the formation of EnLink in the first quarter of 2014, Devon considers EnLink to be an operating segment that is distinct from its existing operating segments. EnLink’s operations consist of midstream assets and operations located across the United States. Additionally, EnLink has a management team that is primarily responsible for capital and resource allocation decisions. Therefore, EnLink is presented as a separate reporting segment. For the reporting periods prior to the formation of EnLink, Devon has reclassified, from its U.S. segment to the EnLink segment, all asset-level amounts related to the midstream assets that it contributed to EnLink Holdings.

Summary Of Significant Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying consolidated financial statements include the accounts of Devon and entities in which it holds a controlling interest. All intercompany transactions have been eliminated. Undivided interests in oil and natural gas exploration and production joint ventures are consolidated on a proportionate basis. Investments in non-controlled entities, over which Devon has the ability to exercise significant influence over operating and financial policies, are accounted for using the equity method. In applying the equity method of accounting, the investments are initially recognized at cost, and subsequently adjusted for Devon’s proportionate share of earnings, losses, and distributions. Investments accounted for using the equity method and cost method are reported as a component of other long-term assets.
	As discussed more fully in Note 2, on March 7, 2014, Devon completed a business combination whereby Devon controls both EnLink Midstream Partners, LP (the “Partnership”) and its general partner entity, EnLink Midstream, LLC (“EnLink”). Devon controls both the Partnership’s and EnLink’s operations; therefore, the Partnership and EnLink’s accounts are included in Devon’s accompanying consolidated financial statements subsequent to the completion of the transaction. The portions of the Partnership and EnLink’s net earnings and stockholders’ equity not attributable to Devon’s controlling interest are shown separately as noncontrolling interests in the accompanying consolidated comprehensive statements of earnings and consolidated balance sheets.
Intangible Assets	'
	Intangible Assets
	EnLink’s long-term assets include intangible assets,  consisting of customer relationships. These assets are amortized on a straight-line basis over the expected periods of benefits, which range from fifteen to twenty years.

Covenant description

'

'

'

'

'

'

'

'

'

'

'

'

'

'The credit facility contains certain financial, operational and legal covenants. Among other things, these covenants include maintaining a ratio of consolidated indebtedness to EnLink's consolidated EBITDA (as defined in the credit facility, which definition includes projected EnLink EBITDA from certain capital expansion projects) of no more than 5.0 to 1.0. If EnLink consummates one or more acquisitions in which the aggregate purchase price is $50 million or more, the maximum allowed ratio of consolidated indebtedness to EnLink's consolidated EBITDA will increase to 5.5 to 1.0 for the quarter of the acquisition and the three following quarters.

'

'The financial covenants will be tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter, and include (i)B maintaining a maximum consolidated leverage ratio (as defined in the credit facility, but generally computed as the ratio of consolidated funded indebtedness to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) of 4.00 to 1.00, provided that the maximum consolidated leverage ratio is 4.50 to 1.00 during an acquisition period (as defined in the credit facility) and (ii)B maintaining a minimum consolidated interest coverage ratio (as defined in the credit facility, but generally computed as the ratio of consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges to consolidated interest charges) of 2.50 to 1.00 at all times prior to the occurrence of an investment grade event (as defined in the credit facility).
