Acquisitions And Divestitures	2. Acquisitions and Divestitures Devon Acquisitions On January 7, 2016, Devon acquired approximately 80,000 net acres and assets in the STACK play for approximately $1.5 billion. Devon funded the acquisition with $849 million of cash and $659 million of common equity shares. The allocation of the purchase price at September 30, 2016 was approximately $1.3 billion to unproved properties and approximately $200 million to proved properties. EnLink Acquisitions On January 7, 2016, EnLink acquired Anadarko Basin gathering and processing midstream assets, along with dedicated acreage service rights and service contracts, for approximately $1.5 billion, subject to certain adjustments. EnLink funded the acquisition with approximately $215 million of General Partner common units and approximately $800 million of cash, primarily funded with the issuance of EnLink preferred units. The remaining $500 million of the purchase price is to be paid within one year with the option to defer $250 million of the final payment 24 months from the close date. The first $250 million of undiscounted future installment payment is reported in other current liabilities in the accompanying consolidated balance sheets with the remaining $250 million payment reported in other long-term liabilities. The accretion of the discount is reported within net financing costs in the accompanying consolidated comprehensive statement of earnings. A preliminary allocation of the purchase price at September 30, 2016 was $1.0 billion to intangible assets and approximately $400 million to property and equipment. On August 1, 2016, EnLink formed a joint venture to operate and expand its midstream assets in the Delaware Basin. The joint venture is initially owned 50.1% by EnLink and 49.9% by the joint venture partner. As of September 30, 2016, EnLink contributed approximately $244 million of existing non-monetary assets to the joint venture and had committed an additional $262 million in capital to fund potential future development projects and potential acquisitions. The joint venture partner committed an aggregate of approximately $400 million of capital, including cash contributions of approximately $138 million, and granted EnLink call rights beginning in 2021 to acquire increasing portions of the joint venture partner’s interest. Devon Asset Divestitures In the first nine months of 2016, Devon divested certain non-core upstream assets in the U.S., and subsequent to quarter-end, completed the divestiture of its 50% interest in the Access Pipeline in Canada. Upstream Asset Sales In the second quarter of 2016, Devon divested its non-core Mississippian assets for approximately $200 million. Estimated proved reserves associated with these assets were approximately 11 MMBoe, or less than 1% of total U.S. proved reserves. During the third quarter of 2016, in several separate transactions with different purchasers, Devon divested non-core upstream assets located in east Texas, the Anadarko Basin and the Midland Basin for approximately $1.7 billion. Estimated proved reserves associated with these assets were approximately 146 MMBoe, or approximately 9% of total U.S. proved reserves. Proceeds from the transactions have been utilized primarily for debt repayment and to support future capital investment in Devon’s core resource plays. Under full cost accounting rules, sales or other dispositions of oil and gas properties are generally accounted for as adjustments to capitalized costs, with no recognition of gain or loss. However, if not recognizing a gain or loss on the disposition would otherwise significantly alter the relationship between a cost center’s capitalized costs and proved reserves, then a gain or loss must be recognized. Absent gain recognition, the divestiture transactions that closed in the third quarter of 2016 would have significantly altered the costs and reserves relationship. Therefore, Devon recognized a $1.4 billion gain in the third quarter of 2016 associated with these divestitures. A summary of the gain computation follows. Three Months Ended September 30, 2016 (Millions) Proceeds received, net of purchase price adjustments and selling costs $ 1,653 Asset retirement obligation assumed by purchasers 250 Total consideration received 1,903 Allocated oil and gas property basis sold 355 Allocated goodwill 197 Total assets sold 552 Gains on asset sales $ 1,351 Access Pipeline Divestiture As of September 30, 2016, the Access Pipeline assets and liabilities were classified as held for sale in the accompanying consolidated balance sheet. In October 2016, Devon divested Access Pipeline for $1.1 billion ($1.4 billion Canadian dollars) and recognized a gain of approximately $540 million on the transaction. In conjunction with the divestiture, Devon entered into a transportation agreement whereby Devon’s Canadian thermal-oil acreage is dedicated to Access Pipeline for an initial term of 25 years. Devon will be charged a market-based toll on its thermal-oil production over this term. In addition, Devon will receive an incremental payment of approximately $120 million upon the sanctioning and development of a new thermal-oil project on Devon’s Pike lease in Alberta.

Derivative Instruments And Hedging Activities Disclosure [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 to hedge future prices received. Additionally, Devon and EnLink periodically enter into derivative financial instruments with respect to a portion of their oil, gas and NGL marketing activities. These commodity derivative financial instruments 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 and foreign exchange forward contracts to manage its exposure to fluctuations in the U.S. and Canadian dollar exchange rates. As of September 30, 2016, Devon did not have any open foreign exchange contracts. 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. As of December 31, 2015, Devon’s other current assets in the accompanying consolidated balance sheet included $236 million of accrued settlements that it received in January 2016. 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 generally contain provisions that provide for collateral payments, if Devon’s or its counterparty’s credit rating falls below certain credit rating levels. As of December 31, 2015, Devon held $75 million of cash collateral which represented the estimated fair value of certain derivative positions in excess of Devon’s credit guidelines. The collateral is reported in other current liabilities in the accompanying consolidated balance sheets. Commodity Derivatives As of September 30, 2016, Devon had the following open oil derivative positions.

Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 2016 2015 (Millions) U.S. oil and gas assets $ 317 $ 4,715 $ 2,810 $ 14,340 Canada oil and gas assets — 336 1,166 336 EnLink goodwill — 576 873 576 EnLink other intangible assets — 223 — 223 Other assets 2 1 2 4 Total asset impairments $ 319 $ 5,851 $ 4,851 $ 15,479 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% 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 from declines in the U.S. and Canada full cost ceilings. The lower ceiling values resulted primarily from significant decreases in the 12-month average trailing prices for oil, bitumen, gas and NGLs, which significantly reduced proved reserves values and, to a lesser degree, proved reserves. EnLink Goodwill Impairments and Other Intangible Assets Impairments In the first quarter of 2016 and the third quarter of 2015, Devon recognized goodwill and other intangible assets impairments related to EnLink’s business. Additional information regarding the impairments is discussed in Note 12.

Of these employee-related costs, approximately $60 million resulted from accelerated vesting of share-based grants, which are noncash charges. Additionally, approximately $30 million resulted from estimated defined benefit settlements. These cash and noncash charges included estimates for employees released from service during the first nine months of 2016, as well as amounts based on the number of employees expected to be impacted by certain of its non-core asset divestitures. As a result of the reduction in workforce and asset divestitures, Devon ceased using certain office space that was subject to non-cancellable operating lease arrangements. Consequently, Devon recognized $17 million of restructuring costs that represent the present value of its future obligations under the leases. Additionally, Devon recognized $3 million of asset impairment charges for leasehold improvements and furniture associated with the office space it ceased using. Transaction Costs In the first nine months of 2016, Devon and EnLink recognized transaction costs primarily associated with the closing of the acquisitions discussed in Note 2.

Statutory tax rate changes and other significant or unusual items are recognized as discrete items in the quarter in which they occur. At December 31, 2015, Devon recorded a 100%, or $967 million, valuation allowance against the U.S. deferred tax assets that largely resulted from the full cost impairments recognized during 2015. In the first and second quarters of 2016, Devon provided an additional $808 and $467 million, respectively, deferred tax valuation allowance to reflect its continued financial losses incurred largely by the additional full cost impairments. In the third quarter of 2016, Devon’s U.S. segment reduced its deferred tax valuation allowance by $479 million primarily due to the gain from the sale of assets recorded during the quarter. Also during the third quarter of 2016, Devon’s Canadian segment recorded a $71 million partial valuation allowance due to its continued financial losses. In the first quarter of 2016 and the third quarter of 2015, EnLink recorded goodwill and intangibles impairments totaling $873 million and $799 million, respectively. These impairments are not deductible for purposes of calculating income tax and therefore have an impact on the effective tax rate. Devon is under audit in the U.S. and various foreign jurisdictions as part of its normal course of business. The timing of resolution of income tax examinations is uncertain as are the amounts and timing of tax payments that are part of any audit settlement process. Devon believes that within the next 12 months, it is reasonably possible that certain tax examinations will be resolved by settlement with the taxing authorities. During the third quarter of 2016, Devon recognized $85 million of unrecognized tax benefits, including $34 million of interest, associated with such tax examinations.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill And Other Intangible Assets	1 2 . Goodwill and Other Intangible Assets Goodwill Devon performs an annual impairment test of goodwill at October 31, or more frequently if events or changes in circumstances indicate that the carrying value of a reporting unit may not be recoverable. Sustained weakness in the overall energy sector driven by low commodity prices, together with a decline in EnLink’s unit price, caused a change in circumstances warranting an interim impairment test of EnLink’s reporting units in the first quarter of 2016. Based on that test, EnLink recorded a noncash goodwill impairment of $873 million. This consisted of a full impairment charge of $93 million related to its Crude and Condensate reporting unit and partial impairment to its Texas and General Partner reporting units of $473 million and $307 million, respectively. In the third quarter of 2015, EnLink recorded a noncash goodwill impairment of $576 million related to its Louisiana reporting unit as a result of an interim impairment test. Asset Divestitures During the third quarter of 2016, Devon derecognized $197 million of goodwill in conjunction with the upstream oil and gas asset divestitures discussed in Note 2. Other Intangible Assets The following table presents other intangible assets reported in other long-term assets in the accompanying consolidated balance sheets. See Note 2 for discussion of changes in other intangible assets resulting from EnLink acquisitions during the first nine months of 2016. In the third quarter of 2015, Devon recorded a noncash intangible assets impairment of $223 million related to EnLink’s Crude and Condensate reporting unit resulting from an assessment of EnLink’s customer relationships. Level 3 fair value measurements were utilized for the impairment analysis of definite-lived intangible assets, which included discounted cash flow estimates, consistent with those utilized in the goodwill impairment assessment. September 30, 2016 December 31, 2015 (Millions) Customer relationships $ 1,793 $ 745 Accumulated amortization (142 ) (55 ) Net intangibles $ 1,651 $ 690 The weighted-average amortization period for other intangible assets is 14 years. Amortization expense for intangibles was approximately $29 million and $14 million for the three months ended September 30, 2016 and 2015, respectively, and $87 million and $44 million for the nine months ended September 30, 2016 and 2015, respectively.

There were no outstanding borrowings under the Senior Credit Facility at September 30, 2016. 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%. Under the terms of the credit agreement, total capitalization is adjusted to add back noncash financial write-downs such as full cost ceiling impairments or goodwill impairments. As of September 30, 2016, Devon was in compliance with this covenant with a debt-to-capitalization ratio of 20.6%. EnLink Debt All of EnLink’s and the General Partner’s debt is non-recourse to Devon. EnLink has a $1.5 billion unsecured revolving credit facility.

In addition, during the first nine months of 2016, EnLink issued approximately 7 million common units for net proceeds of $110 million. As a result of these transactions, Devon’s ownership interest in EnLink decreased from 28% at December 31, 2015 to 24% at September 30, 2016, excluding the interest held by the General Partner. Additionally, as a result of the transaction described in Note 2, Devon’s ownership in the General Partner decreased from 70% to 64% during the same time period. The net gains and losses and related income taxes resulting from these transactions have been recorded as an adjustment to equity, with the change in ownership reflected as an adjustment to noncontrolling interests. Distributions to Noncontrolling Interests EnLink and the General Partner distributed $224 million and $186 million to non-Devon unitholders during the first nine months of 2016 and 2015, respectively.

Commitments And Contingencies	19. 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 is also involved in governmental agency proceedings and is subject to related contracts and regulatory controls in the ordinary course of business, some that may lead to additional royalty claims. 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 environmental, health and safety laws and regulations, including 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 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.

Fair Value Disclosures [Abstract]
Fair Value Measurements	20. Fair Value Measurements The following table provides carrying value and fair value measurement information for certain of Devon’s financial assets and liabilities. The carrying values of cash, accounts receivable, other current receivables, accounts payable, other current payables and accrued expenses included in the accompanying consolidated balance sheets approximated fair value at September 30, 2016 and December 31, 2015. Therefore, such financial assets and liabilities are not presented in the following table. Additionally, the fair values of oil and gas assets, goodwill and other intangible assets and related impairments are measured as of the impairment date using Level 3 inputs. More information on these items is provided in Note 5 and Note 12.

Level 1 Fair Value Measurements Cash equivalents – Amounts consist primarily of money market investments. The fair value approximates the carrying value. Level 2 Fair Value Measurements Cash equivalents – Amounts consist primarily of commercial paper and Canadian agency and provincial securities 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 values of commercial paper and credit facility balances are the carrying values. Installment payment – The fair value of the EnLink installment payment as of September 30, 2016 was based on Level 2 inputs from third-party market quotations. Capital lease obligations – The fair value was calculated using inputs from third-party banks.

Segment Reporting [Abstract]
Segment Information	21. 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 E&P 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 both primarily engaged in oil and gas E&P activities. Devon considers EnLink, combined with the General Partner, to be an operating segment that is distinct from the U.S. and Canadian operating segments. EnLink’s operations consist of midstream assets and operations located across the U.S. 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.
