Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | 1. Basis of Presentation and Principles of Consolidation Encana is in the business of the exploration for, the development of, and the production and marketing of oil, NGLs and natural gas. The interim Condensed Consolidated Financial Statements include the accounts of Encana and entities in which it holds a controlling interest. All intercompany balances and transactions are eliminated on consolidation. Undivided interests in oil and natural gas exploration and production joint ventures and partnerships are consolidated on a proportionate basis. Investments in non-controlled entities over which Encana has the ability to exercise significant influence are accounted for using the equity method. The interim Condensed Consolidated Financial Statements are prepared in conformity with U.S. GAAP and the rules and regulations of the SEC. Pursuant to these rules and regulations, certain information and disclosures normally required under U.S. GAAP have been condensed or have been disclosed on an annual basis only. Accordingly, the interim Condensed Consolidated Financial Statements should be read in conjunction with the annual audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2017, which are included in Item 8 of Encana’s 2017 Annual Report on Form 10-K. The interim Condensed Consolidated Financial Statements have been prepared following the same accounting policies and methods of computation as the annual audited Consolidated Financial Statements for the year ended December 31, 2017, except as noted below in Note 2. The disclosures provided below are incremental to those included with the annual audited Consolidated Financial Statements. These unaudited interim Condensed Consolidated Financial Statements reflect, in the opinion of Management, all normal and recurring adjustments necessary to present fairly the financial position and results of the Company as at and for the periods presented. Interim condensed consolidated financial results are not necessarily indicative of consolidated financial results expected for the fiscal year. |

New Accounting Pronouncements and Changes in Accounting Principles [Abstract] | |
Recent Accounting Pronouncements | 2. Recent Accounting Pronouncements Changes in Accounting Policies and Practices On January 1, 2018, Encana adopted the following ASUs issued by the FASB, which have not had a material impact on the Company's interim Condensed Consolidated Financial Statements: · ASU 2014-09, “Revenue from Contracts with Customers” under Topic 606. The new standard replaces Topic 605, “Revenue Recognition” as well as other industry-specific guidance within the Accounting Standards Codification. Topic 606 is based on the principle that revenue is recognized on the transfer of promised goods or services to customers in an amount that reflects the consideration the company expects to be entitled to in exchange for those goods or services. The standard has been applied using the modified retrospective approach and did not have a material impact on the Company’s Condensed Consolidated Financial Statements, other than enhancing disclosures related to the disaggregation of revenues from contracts with customers and performance obligations . The disclosures required under Topic 606 are included in Note 4, Revenues from Contracts with Customers. · ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The amendment requires the service cost component to be presented with the related employee compensation costs, while the other components of net benefit costs are required to be presented separately from the service cost component and outside the subtotal of income from operations. In addition, the amendment allows only the service cost to be eligible for capitalization. The amendment has been applied retrospectively for the presentation of net periodic pension costs and net periodic postretirement benefit cost, whereas prospective adoption has been applied to the capitalization of the service cost component. New Standards Issued Not Yet Adopted As of January 1, 2019, Encana will be required to adopt ASU 2016-02, “Leases” under Topic 842, which will replace Topic 840 “Leases”. The new standard will require lessees to recognize right-of-use assets and related lease liabilities for all leases, including leases classified as operating leases, on the Consolidated Balance Sheet. The dual classification model was retained for the purpose of subsequent measurement and presentation of leases in the Consolidated Statement of Earnings and Consolidated Statement of Cash Flows. Topic 842 also expands disclosures related to the amount, timing and uncertainty of cash flows arising from leases. The standard will be applied using a modified retrospective approach, in addition Encana intends to elect certain practical expedients which will allow the Company to retain the classification of leases assessed under Topic 840 which commenced prior to adoption. In January 2018, FASB issued ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”, which permits entities to elect an optional transition practical expedient for land easements that were not previously accounted for as leases under Topic 840. The expedient provides prospective application of Topic 842 to all new or modified land easements upon adoption of the new standard. Encana intends to elect this transitional practical expedient. Encana continues to review and analyze contracts, identify its portfolio of leased assets, gather the necessary terms and data elements, as well as identify the processes and controls required to support the accounting for leases and related disclosures. The Company is in the early stages of implementing a lease software system which will facilitate the measurement and required disclosures for operating leases. The Company anticipates the software implementation to be complete by the end of 2018. Although Encana is not able to reasonably estimate the financial impact of Topic 842 at this time, the Company anticipates there will be a material impact on the Consolidated Financial Statements resulting from the recognition of assets and liabilities from operating lease activities. As of January 1, 2019, Encana will be required to adopt ASU 2018-02 “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The amendments allow for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (“U.S. Tax Reform”). Amendments can be applied either in the period of adoption or retrospectively to each period in which the effect of the rate change from the U.S. Tax Reform is recognized. While Encana has other post-employment benefit plans which were affected by the U.S. Tax Reform, the impact is not material to the Company’s Consolidated Financial Statements. As a result, the Company does not intend to take the election provided in the amendment. As of January 1, 2020, Encana will be required to adopt ASU 2017-04, “Simplifying the Test for Goodwill Impairment”. The amendment eliminates the second step of the goodwill impairment test which requires the Company to measure the impairment based on the excess amount of the carrying value of the reporting unit’s goodwill over the implied fair value of its goodwill. Under this amendment, the goodwill impairment will be measured based on the excess amount of the reporting unit’s carrying value over its respective fair value. The amendment will be applied prospectively at the date of adoption. Encana is currently in the early stages of reviewing the amendment, but does not expect the amendment to have a material impact on the Company’s Consolidated Financial Statements. |

Segmented Information [Abstract] | |
Segmented Information | 3. Segmented Information Encana’s reportable segments are determined based on the Company’s operations and geographic locations as follows: · Canadian Operations includes the exploration for, development of, and production of oil, NGLs and natural gas and other related activities within the Canadian cost centre. · USA Operations includes the exploration for, development of, and production of oil, NGLs and natural gas and other related activities within the U.S. cost centre. · Market Optimization is primarily responsible for the sale of the Company’s proprietary production. These results are reported in the Canadian and USA Operations. Market optimization activities include third party purchases and sales of product to provide operational flexibility and cost mitigation for transportation commitments, product type, delivery points and customer diversification. These activities are reflected in the Market Optimization segment. Market Optimization sells substantially all of the Company’s upstream production to third party customers. Transactions between segments are based on market values and are eliminated on consolidation. Corporate and Other mainly includes unrealized gains or losses recorded on derivative financial instruments. Once the instruments are settled, the realized gains and losses are recorded in the reporting segment to which the derivative instruments relate. Corporate and Other also includes amounts related to sublease rentals.

(2) Canadian and USA Operations includes realized gains/(losses) on risk management. Corporate & Other includes unrealized gains/(losses) on risk management. (3) Corporate interest income of $8 million previously reported in revenues in Q1 2017 has been reclassified to other (gains) losses, net. The Company’s revenues from contracts with customers consists of product sales including oil, NGLs and natural gas, as well as the provision of gathering and processing services to third parties. Encana had no contract asset or liability balances during the periods presented. As at March 31, 2018, receivables and accrued revenues from contracts with customers were $658 million ( $676 million as at December 31, 2017). Performance obligations arising from product sales contracts are typically satisfied at a point in time when the product is delivered to the customer and control is transferred . Payment from the customer is due when the product is delivered to the custody point. The Company’s product sales are sold under short-term contracts with terms that are less than one year at either fixed or market index prices or under long-term contracts exceeding one year at market index prices. As at March 31, 2018, all remaining performance obligations are priced at market index prices or are variable volume delivery contracts. As such, the variable consideration is allocated entirely to the wholly unsatisfied performance obligation or promise to deliver units of production, and revenue is recognized at the amount for which the Company has the right to invoice the product delivered. Performance obligations arising from arrangements to gather and process natural gas on behalf of third parties are typically satisfied over time as the service is provided to the customer. Payment from the customer is due when the customer receives the benefit of the service and the product is delivered to the custody point or plant tailgate. The Company’s gathering and processing services are provided on an interruptible basis with transaction prices that are for fixed prices and/or variable consideration. Variable consideration received is related to recovery of plant operating costs or escalation of the fixed price based on a consumer price index. As the service contracts are interruptible, with service provided on an “as available” basis, there are no unsatisfied performance obligations remaining at March 31, 2018. |

The estimated annual effective income tax rate is impacted by expected annual earnings, income tax related to foreign operations, the effect of legislative changes including U.S. Tax Reform, non-taxable capital gains and losses, tax differences on divestitures and transactions, and partnership tax allocations in excess of funding. During the three months ended March 31, 2017, the current income tax recovery was primarily due to the successful resolution of certain tax items previously assessed by the taxing authorities relating to prior taxation years. The effective tax rates of 5.6 percent and 0.7 percent for the three months ended March 31, 2018 and March 31, 2017, respectively, are lower than the Canadian statutory rate of 27 percent primarily due to the impact of the foreign jurisdictional tax rates relative to the Canadian statutory tax rate applied to jurisdictional earnings as well as the items discussed above. During the three months ended March 31, 2018, there was no change to the provisional tax adjustment recognized in 2017 resulting from the re-measurement of the Company’s tax position due to a reduction of the U.S. federal corporate tax rate under U.S. Tax Reform. The provisional amount recognized may change due to additional regulatory guidance that may be issued, and from additional analysis or changes in interpretation and assumptions of the U.S. Tax Reform made by the Company. |

During the twelve months ended December 31, 2017, Encana issued 58,480 common shares totaling $0.6 million under the DRIP. Dividends During the three months ended March 31, 2018, Encana paid dividends of $0.015 per common share totaling $15 million (2017 - $0.015 per common share totaling $15 million). For the three months ended March 31, 2018, the dividends paid included $0.3 million in common shares issued in lieu of cash dividends under the DRIP (2017 - $ 0.2 million). On April 30, 2018 , the Board of Directors declared a dividend of $0.015 per common share payable on June 29, 2018 to common shareholders of record as of June 15, 2018 . Normal Course Issuer Bid On February 26, 2018, the Company announced it received approval from the TSX to purchase, for cancellation, up to 35 million common shares pursuant to a normal course issuer bid (“NCIB”) over a 12-month period from February 28, 2018 to February 27, 2019 . The Company has authorization from its Board to spend up to $400 million on the NCIB. All purchases are made in accordance with the NCIB at prevailing market prices plus brokerage fees, with consideration allocated to share capital up to the average carrying amount of the shares, and any excess is allocated to retained earnings/accumulated deficit. During the three months ended March 31, 2018 , the Company purchased 10 million common shares for total consideration of approximately $111 million. Of the amount paid, $50 million was charged to share capital and $61 million was charged to accumulated deficit. Earnings Per Common Share The following table presents the computation of net earnings (loss) per common share: Three Months Ended March 31, (US$ millions, except per share amounts) 2018 2017 Net Earnings (Loss) $ 151 $ 431 Number of Common Shares: Weighted average common shares outstanding - Basic 971.5 973.0 Effect of dilutive securities - - Weighted average common shares outstanding - Diluted 971.5 973.0 Net Earnings (Loss) per Common Share Basic & Diluted $ 0.16 $ 0.44 Encana Stock Option Plan Encana has share-based compensation plans that allow employees to purchase common shares of the Company. Option exercise prices are not less than the market value of the common shares on the date the options are granted. All options outstanding as at March 31, 2018 have associated Tandem Stock Appreciation Rights (“TSARs”) attached. In lieu of exercising the option, the associated TSARs give the option holder the right to receive a cash payment equal to the excess of the market price of Encana’s common shares at the time of the exercise over the original grant price. In addition, certain stock options granted are performance-based whereby vesting is also subject to Encana attaining prescribed performance relative to predetermined key measures. Historically, most holders of options with TSARs have elected to exercise their stock options as a Stock Appreciation Right (“SAR”) in exchange for a cash payment. As a result, outstanding TSARs are not considered potentially dilutive securities. Encana Restricted Share Units (“RSUs”) Encana has a share-based compensation plan whereby eligible employees and Directors are granted RSUs. An RSU is a conditional grant to receive the equivalent of an Encana common share upon vesting of the RSUs and in accordance with the terms of the RSU Plan and Grant Agreement. The Company currently settles vested RSUs in cash. As a result, RSUs are not considered potentially dilutive securities. |

Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract] | |
Variable Interest Entity Disclosure | 15. Variable Interest Entities Production Field Centre In 2008, Encana entered into a contract for the design, construction and operation of the PFC at its Deep Panuke facility. Upon commencement of operations in December 2013, Encana recognized the PFC as a capital lease asset. Under the lease contract, Encana has a purchase option and the option to extend the lease for 12 one -year terms at fixed prices after the initial lease term expires in 2021 . As a result of the purchase option and fixed price renewal options, Encana has determined it holds variable interests and that the related leasing entity qualifies as a variable interest entity (“VIE”). Encana is not the primary beneficiary of the VIE as the Company does not have the power to direct the activities that most significantly impact the VIE’s economic performance. Encana is not required to provide any financial support or guarantees to the leasing entity or its affiliates, other than the contractual payments under the lease and operating agreements. Encana’s maximum exposure is the expected lease payments over the initial contract term. As at March 31, 2018, Encana had a capital lease obligation of $296 million ( $314 million as at December 31, 2017) related to the PFC. Veresen Midstream Limited Partnership Veresen Midstream Limited Partnership (“VMLP”) provides gathering, compression and processing services under various agreements related to the Company’s development of liquids and natural gas production in the Montney play. As at March 31, 2018, VMLP provides approximately 1,110 MMcf/d of natural gas gathering and compression and 600 MMcf/d of natural gas processing under long-term service agreements with remaining terms ranging from up to 13 to 27 years and have various renewal terms providing up to a potential maximum of 10 years. Encana has determined that VMLP is a VIE and that Encana holds variable interests in VMLP. Encana is not the primary beneficiary as the Company does not have the power to direct the activities that most significantly impact VMLP’s economic performance. These key activities relate to the construction, operation, maintenance and marketing of the assets owned by VMLP. The variable interests arise from certain terms under the various long-term service agreements and include: i) a take or pay for volumes in certain agreements; ii) an operating fee of which a portion can be converted into a fixed fee once VMLP assumes operatorship of certain assets; and iii) a potential payout of minimum costs in certain agreements. The potential payout of minimum costs will be assessed in the eight h year of the assets’ service period and is based on whether there is an overall shortfall of total system cash flows from natural gas gathered and compressed under certain agreements. The potential payout amount can be reduced in the event VMLP markets unutilized capacity to third party users. Encana is not required to provide any financial support or guarantees to VMLP. As a result of Encana’s involvement with VMLP, the maximum total exposure, which represents the potential exposure to Encana in the event the assets under the agreements are deemed worthless, is estimated to be $2,390 million as at March 31, 2018. The estimate comprises the take or pay volume commitments and the potential payout of minimum costs. The take or pay volume commitments associated with certain gathering and processing assets are included in Note 21 under Transportation and Processing. The potential payout requirement is highly uncertain as the amount is contingent on future production estimates, pace of development and the amount of capacity contracted to third parties. As at March 31, 2018, there were no accounts payable and accrued liabilities outstanding related to the take or pay commitment. |

Compensation Plans [Abstract] | |
Compensation Plans | 16. Compensation Plans Encana has a number of compensation arrangements under which the Company awards various types of long-term incentive grants to eligible employees and Directors. They may include TSARs, Performance TSARs, SARs, Performance Share Units (“PSUs”), Deferred Share Units (“DSUs”) and RSUs. These compensation arrangements are share-based. Encana accounts for TSARs, Performance TSARs, SARs, PSUs and RSUs held by employees as cash-settled share-based payment transactions and, accordingly, accrues compensation costs over the vesting period based on the fair value of the rights determined using the Black-Scholes-Merton and other fair value models. The following weighted average assumptions were used to determine the fair value of the share units held by employees: As at March 31, 2018 As at March 31, 2017 US$ Share Units C$ Share Units US$ Share Units C$ Share Units Risk Free Interest Rate 1.79% 1.79% 0.74% 0.74% Dividend Yield 0.55% 0.54% 0.51% 0.51% Expected Volatility Rate (1) 58.46% 54.78% 58.12% 54.02% Expected Term 2.0 yrs 2.1 yrs 1.9 yrs 1.9 yrs Market Share Price US$11.00 C$14.17 US$11.71 C$15.58 (1) Volatility was estimated using historical rates.

Fair Value Measurements [Abstract] | |
Fair Value Measurements | 18. Fair Value Measurements The fair values of cash and cash equivalents, accounts receivable and accrued revenues, and accounts payable and accrued liabilities approximate their carrying amounts due to the short-term maturity of those instruments. Recurring fair value measurements are performed for risk management assets and liabilities and other derivative contracts, as discussed further in Note 19. These items are carried at fair value in the Condensed Consolidated Balance Sheet and are classified within the three levels of the fair value hierarchy in the following tables. There have been no significant transfers between the hierarchy levels during the period. Fair value changes and settlements for amounts related to risk management assets and liabilities are recognized in revenues, transportation and processing expense, and foreign exchange gains and losses according to their purpose.

The Company’s Level 1 and Level 2 risk management assets and liabilities consist of commodity fixed price contracts, fixed price swaptions, NYMEX call options, foreign currency swaps and basis swaps with terms to 2023. Level 2 also includes financial guarantee contracts as discussed in Note 19. The fair values of these contracts are based on a market approach and are estimated using inputs which are either directly or indirectly observable at the reporting date, such as exchange and other published prices, broker quotes and observable trading activity. Level 3 Fair Value Measurements As at March 31, 2018, the Company’s Level 3 risk management assets and liabilities consist of WTI three-way options and WTI costless collars with terms to 2018. The WTI three-way options are a combination of a sold call, bought put and a sold put. The WTI costless collars are a combination of a sold call and a bought put. These contracts allow the Company to participate in the upside of commodity prices to the ceiling of the call option and provide the Company with complete (collars) or partial (three-way) downside price protection through the put options. The fair values of the WTI three-way options and WTI costless collars are based on the income approach and are modelled using observable and unobservable inputs such as implied volatility. The unobservable inputs are obtained from third parties whenever possible and reviewed by the Company for reasonableness. A summary of changes in Level 3 fair value measurements for the three months ended March 31 is presented below: Risk Management 2018 2017 Balance, Beginning of Year $ (51) $ (36) Total Gains (Losses) 6 41 Purchases, Sales, Issuances and Settlements: Purchases, sales and issuances - - Settlements (17) - Transfers Out of Level 3 (1) - - Balance, End of Period $ (62) $ 5 Change in Unrealized Gains (Losses) Related to Assets and Liabilities Held at End of Period $ (24) $ 40 (1) The Company’s policy is to recognize transfers out of Level 3 on the date of the event of change in circumstances that caused the transfer. Quantitative information about unobservable inputs used in Level 3 fair value measurements is presented below: Valuation Technique Unobservable Input As at March 31, 2018 As at December 31, 2017 Risk Management - WTI Options Option Model Implied Volatility 24% - 83% 17% - 76% A 10 percent increase or decrease in implied volatility for the WTI options would cause a corresponding $1 million ( $2 million as at December 31, 2017) increase or decrease to net risk management assets and liabilities. |

Financial Instruments And Risk Management [Abstract] | |
Financial Instruments and Risk Management | 19. Financial Instruments and Risk Management A) Financial Instruments Encana’s financial assets and liabilities are recognized in cash and cash equivalents, accounts receivable and accrued revenues, accounts payable and accrued liabilities, risk management assets and liabilities, long-term debt and other liabilities and provisions. B) Risk Management Activities Encana uses derivative financial instruments to manage its exposure to cash flow variability from commodity prices and fluctuating foreign currency exchange rates. The Company does not apply hedge accounting to any of its derivative financial instruments. As a result, gains and losses from changes in the fair value are recognized in net earnings. Commodity Price Risk Commodity price risk arises from the effect that fluctuations in future commodity prices may have on future cash flows. To partially mitigate exposure to commodity price risk, the Company has entered into various derivative financial instruments. The use of these derivative instruments is governed under formal policies and is subject to limits established by the Board of Directors. The Company’s policy is to not use derivative financial instruments for speculative purposes. Crude Oil and NGLs - To partially mitigate crude oil and NGL commodity price risk, the Company uses WTI-based contracts such as fixed price contracts, fixed price swaptions, options and costless collars. Encana has also entered into basis swaps to manage against widening price differentials between various production areas and benchmark price points. Natural Gas - To partially mitigate natural gas commodity price risk, the Company uses NYMEX-based contracts such as fixed price contracts, fixed price swaptions and options. Encana has also entered into basis swaps to manage against widening price differentials between various production areas and benchmark price points. Foreign Exchange Risk Foreign exchange risk arises from changes in foreign currency exchange rates that may affect the fair value or future cash flows of the Company’s financial assets or liabilities. To partially mitigate the effect of foreign exchange fluctuations on future commodity revenues and expenses, the Company may enter into foreign currency derivative contracts. As at March 31, 2018, Encana has entered into $538 million notional U.S. dollar denominated currency swaps at an average exchange rate of US$0.7606 to C$1, which mature monthly through the remainder of 2018 .

While exchange-traded contracts are subject to nominal credit risk due to the financial safeguards established by the New York Stock Exchange and the TSX, over-the-counter traded contracts expose Encana to counterparty credit risk. This credit risk exposure is mitigated through the use of credit policies approved by the Board of Directors governing the Company’s credit portfolio including credit practices that limit transactions according to counterparties’ credit quality. Mitigation strategies may include master netting arrangements, requesting collateral and/or transacting credit derivatives. The Company executes commodity derivative financial instruments under master agreements that have netting provisions that provide for offsetting payables against receivables. As a result of netting provisions, the Company’s maximum exposure to loss under derivative financial instruments due to credit risk is limited to the net amounts due from the counterparties under the derivative contracts, as disclosed in Note 18. As at March 31, 2018, the Company had no significant credit derivatives in place and held no collateral. As at March 31, 2018, cash equivalents include high-grade, short-term securities, placed primarily with financial institutions and companies with strong investment grade ratings. Any foreign currency agreements entered into are with major financial institutions that have investment grade credit ratings. A substantial portion of the Company’s accounts receivable are with customers in the oil and gas industry and are subject to normal industry credit risks. As at March 31, 2018, approximately 93 percent ( 92 percent as at December 31, 2017) of Encana’s accounts receivable and financial derivative credit exposures were with investment grade counterparties. As at March 31, 2018, Encana had two counterparties whose net settlement position individually accounted for more than 10 percent of the fair value of the outstanding in-the-money net risk management contracts by counterparty. As at March 31, 2018, these counterparties accounted for 53 percent and 11 percent of the fair value of the outstanding in-the-money net risk management contracts. As at December 31, 2017, Encana had three counterparties whose net settlement position accounted for 56 percent, 11 percent and 11 percent of the fair value of the outstanding in-the-money net risk management contracts. During 2015 and 2017, Encana entered into agreements resulting from divestitures, which may require Encana to fulfill certain payment obligations on the take or pay volume commitments assumed by the purchasers. The circumstances that would require Encana to perform under the agreements include events where a purchaser fails to make payment to the guaranteed party and/or a purchaser is subject to an insolvency event. The agreements have remaining terms from three to six years with a fair value recognized of $18 million as at March 31, 2018 ( $19 million as at December 31, 2017). The maximum potential amount of undiscounted future payments is $317 million as at March 31, 2018, and is considered unlikely. |

Divestiture transactions can reduce certain commitments disclosed above. Contingencies Encana is involved in various legal claims and actions arising in the normal course of the Company’s operations. Although the outcome of these claims cannot be predicted with certainty, the Company does not expect these matters to have a material adverse effect on Encana’s financial position, cash flows or results of operations. Management’s assessment of these matters may change in the future as certain of these matters are in early stages or are subject to a number of uncertainties. For material matters that the Company believes an unfavourable outcome is reasonably possible, the Company discloses the nature and a range of potential exposures. If an unfavourable outcome were to occur, there exists the possibility of a material impact on the Company’s consolidated net earnings or loss for the period in which the effect becomes reasonably estimable. The Company accrues for such items when a liability is both probable and the amount can be reasonably estimated. Such accruals are based on the Company’s information known about the matters, estimates of the outcomes of such matters and experience in handling similar matters. |

Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block] | Encana is in the business of the exploration for, the development of, and the production and marketing of oil, NGLs and natural gas. The interim Condensed Consolidated Financial Statements include the accounts of Encana and entities in which it holds a controlling interest. All intercompany balances and transactions are eliminated on consolidation. Undivided interests in oil and natural gas exploration and production joint ventures and partnerships are consolidated on a proportionate basis. Investments in non-controlled entities over which Encana has the ability to exercise significant influence are accounted for using the equity method. The interim Condensed Consolidated Financial Statements are prepared in conformity with U.S. GAAP and the rules and regulations of the SEC. Pursuant to these rules and regulations, certain information and disclosures normally required under U.S. GAAP have been condensed or have been disclosed on an annual basis only. Accordingly, the interim Condensed Consolidated Financial Statements should be read in conjunction with the annual audited Consolidated Financial Statements and the notes thereto for the year ended December 31, 2017, which are included in Item 8 of Encana’s 2017 Annual Report on Form 10-K. The interim Condensed Consolidated Financial Statements have been prepared following the same accounting policies and methods of computation as the annual audited Consolidated Financial Statements for the year ended December 31, 2017, except as noted below in Note 2. The disclosures provided below are incremental to those included with the annual audited Consolidated Financial Statements. These unaudited interim Condensed Consolidated Financial Statements reflect, in the opinion of Management, all normal and recurring adjustments necessary to present fairly the financial position and results of the Company as at and for the periods presented. Interim condensed consolidated financial results are not necessarily indicative of consolidated financial results expected for the fiscal year. |
Recent Accounting Pronouncements | Changes in Accounting Policies and Practices On January 1, 2018, Encana adopted the following ASUs issued by the FASB, which have not had a material impact on the Company's interim Condensed Consolidated Financial Statements: · ASU 2014-09, “Revenue from Contracts with Customers” under Topic 606. The new standard replaces Topic 605, “Revenue Recognition” as well as other industry-specific guidance within the Accounting Standards Codification. Topic 606 is based on the principle that revenue is recognized on the transfer of promised goods or services to customers in an amount that reflects the consideration the company expects to be entitled to in exchange for those goods or services. The standard has been applied using the modified retrospective approach and did not have a material impact on the Company’s Condensed Consolidated Financial Statements, other than enhancing disclosures related to the disaggregation of revenues from contracts with customers and performance obligations . The disclosures required under Topic 606 are included in Note 4, Revenues from Contracts with Customers. · ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. The amendment requires the service cost component to be presented with the related employee compensation costs, while the other components of net benefit costs are required to be presented separately from the service cost component and outside the subtotal of income from operations. In addition, the amendment allows only the service cost to be eligible for capitalization. The amendment has been applied retrospectively for the presentation of net periodic pension costs and net periodic postretirement benefit cost, whereas prospective adoption has been applied to the capitalization of the service cost component. New Standards Issued Not Yet Adopted As of January 1, 2019, Encana will be required to adopt ASU 2016-02, “Leases” under Topic 842, which will replace Topic 840 “Leases”. The new standard will require lessees to recognize right-of-use assets and related lease liabilities for all leases, including leases classified as operating leases, on the Consolidated Balance Sheet. The dual classification model was retained for the purpose of subsequent measurement and presentation of leases in the Consolidated Statement of Earnings and Consolidated Statement of Cash Flows. Topic 842 also expands disclosures related to the amount, timing and uncertainty of cash flows arising from leases. The standard will be applied using a modified retrospective approach, in addition Encana intends to elect certain practical expedients which will allow the Company to retain the classification of leases assessed under Topic 840 which commenced prior to adoption. In January 2018, FASB issued ASU 2018-01, “Land Easement Practical Expedient for Transition to Topic 842”, which permits entities to elect an optional transition practical expedient for land easements that were not previously accounted for as leases under Topic 840. The expedient provides prospective application of Topic 842 to all new or modified land easements upon adoption of the new standard. Encana intends to elect this transitional practical expedient. Encana continues to review and analyze contracts, identify its portfolio of leased assets, gather the necessary terms and data elements, as well as identify the processes and controls required to support the accounting for leases and related disclosures. The Company is in the early stages of implementing a lease software system which will facilitate the measurement and required disclosures for operating leases. The Company anticipates the software implementation to be complete by the end of 2018. Although Encana is not able to reasonably estimate the financial impact of Topic 842 at this time, the Company anticipates there will be a material impact on the Consolidated Financial Statements resulting from the recognition of assets and liabilities from operating lease activities. As of January 1, 2019, Encana will be required to adopt ASU 2018-02 “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income”. The amendments allow for a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (“U.S. Tax Reform”). Amendments can be applied either in the period of adoption or retrospectively to each period in which the effect of the rate change from the U.S. Tax Reform is recognized. While Encana has other post-employment benefit plans which were affected by the U.S. Tax Reform, the impact is not material to the Company’s Consolidated Financial Statements. As a result, the Company does not intend to take the election provided in the amendment. As of January 1, 2020, Encana will be required to adopt ASU 2017-04, “Simplifying the Test for Goodwill Impairment”. The amendment eliminates the second step of the goodwill impairment test which requires the Company to measure the impairment based on the excess amount of the carrying value of the reporting unit’s goodwill over the implied fair value of its goodwill. Under this amendment, the goodwill impairment will be measured based on the excess amount of the reporting unit’s carrying value over its respective fair value. The amendment will be applied prospectively at the date of adoption. Encana is currently in the early stages of reviewing the amendment, but does not expect the amendment to have a material impact on the Company’s Consolidated Financial Statements. |
