New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Changes in Accounting Principles [Text Block]	Note 2 — Changes in Accounting Principles We adopted the provisions of FASB ASU No. 2016-02, “Leases,” and its amendments set forth by the provisions of ASU No. 2018-01, “Land Easement Practical Expedient for Transition to Topic 842,” ASU No. 2018-10, “Codification Improvements to Topic 842, Leases,” ASU No. 2018-11, “Targeted Improv ements,” ASU No. 2018-20, “Narrow-Scope Improvements for Lessors,” and ASU No. 2019-01, “Codification Improvements,” collectively FASB ASC Topic 842, “Leases” (ASC Topic 842), beginning January 1, 2019 . ASC Topic 842 establishes comprehensive accounting and financial reporting requirements for leasing arrangements, supersedes the existing requirements in FASB ASC Topic 840, “Leases” (ASC Topic 840), and requires lessees to recognize substantially all lease assets and lease liabilities on the balance sheet . The provisions of ASC Topic 842 also modify the definition of a lease and outline requirements for recognition, measurement, presentation and disclosure of leasing arrangements by both lessees and lessors. We adopted ASC Topic 842 using the modifie d retrospective approach and elected to utilize the Optional Transition Method, which permits us to apply the provisions of ASC Topic 842 to leasing arrangements existing at or entered into after January 1, 2019, and present in our financial statements com parative periods prior to January 1, 2019 under the historical requirements of ASC Topic 840. In addition, we elected to adopt the package of optional transition-related practical expedients , which among other things, allows us to carry forward certain hi storical conclusions reached under ASC Topic 840 regarding lease identification, classification, and the accounting treatment of initial direct costs. Furthermore, we elected not to record assets and liabilities on our consolidated balance sheet for new o r existing lease arrangements with terms of 12 months or less. The primary impact of applying ASC Topic 842 is the initial recognition of $ 998 m illion of lease liabilities and corresponding right-of-use assets on our consolidated balance sh eet as of January 1, 2019, for leases classified as operating leases under ASC Topic 840, as well as enhanced disclosure of our leasing arrangements. Our accounting treatment for finance leases remains unchanged. In addition, there is no cumulative effec t to retained earnings or other components of equity recognized as of January 1, 2019, and the adoption of ASC Topic 842 did not impact the presentation of our consolidated income statement or statement of cash flows. See Note 15 —Non-Mineral Leases for additional information related to the adoption of ASC Topic 842 . We adopted the provisions of FASB ASU No. 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , ” beginning January 1, 2019. The ASU allows a reclass ification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act, eliminating the stranded tax effects. The cumulative effect to our consolidated balance sheet at January 1, 2019 for the adoption of ASU No. 2018-02 w as as follows Millions of Dollars December 31 ASU No. 2018-02 January 1 2018 Adjustments 2019 Equity Accumulated other comprehensive loss $ (6,063) (40) (6,103) Retained earnings 34,010 40 34,050 For additional information regarding the impact of the adoption of ASU No. 2018-02, see Note 16—Accumulated Other Comprehensive Loss.

Variable Interest Entities (VIEs)	Mar. 31, 2019
Variable Interest Entity[Abstract]
Variable Interest Entity Disclosure [Text Block]	Note 3 — Variable Interest Entities We hold variable interests in VIEs that have not been consolidated because we are not considered the primary beneficiary. Information on our significant VIEs follows: Australia Pacific LNG Pty Ltd (APLNG) APLNG is considered a VIE, as it has entered into certain contractual arrangements that provide it with additional forms of subordinated financial support. We are not the primary beneficiary of APLNG because we share with Origin Energy and China Petrochem ical Corporation (Sinopec) the power to direct the key activities of APLNG that most significantly impact its economic performance, which involve activities related to the production and commercialization of coalbed methane, as well as LNG processing and e xport marketing. As a result, we do not consolidate APLNG, and it is accounted for as an equity method investment. As of March 31, 2019 , we have not provided any financial support to APLNG other than amounts previously contractually required. Unless we elect otherwise, we have no requirement to provide liquidity or purchase the assets of APLNG. See Note 6 —Investments, Loans and Long-Term Receivables, and Note 11 —Guarantees, for additional information. Marine Well Containment Company, LLC (M WCC) MWCC provides well containment equipment and technology and related services in the deepwater U.S. Gulf of Mexico. Its principal activities involve the development and maintenance of rapid-response hydrocarbon well containment systems that are deploy able in the Gulf of Mexico on a call-out basis. We have a 10 percent ownership interest in MWCC, and it is accounted for as an equity method investment because MWCC is a limited liability company in which we are a Founding Member and exercise significant influence through our permanent seat on the ten -member Executive Committee responsible for overseeing the affairs of MWCC. In 2016, MWCC executed a $ 154 million term loan financing arrangement with an external financial institution whose terms required the financing be secured by letters of credit provided by certain owners of MWCC, including ConocoPhillips. In connection with the financing transaction, we issued a letter of credit of $ 22 million which can be drawn upon in the event of a default by MWCC on its obligation to repay the proceeds of the term loan. The fair value of this letter of credit is immaterial and not recognized on our consolidated balance sheet. MWCC is conside red a VIE, as it has entered into arrangements that provide it with additional forms of subordinated financial support. We are not the primary beneficiary and do not consolidate MWCC because we share the power to govern the business and operation of the c ompany and to undertake certain obligations that most significantly impact its economic performance with nine other unaffiliated owners of MWCC. At March 31, 2019 , the carrying value of our equity method investment in MWCC was $ 1 26 million. We have not p rovided any financial support to MWCC other than amounts previously contractually required. Unless we elect otherwise, we have no requirement to provide liquidity or purchase the assets of MWCC.

Disposal Groups Exluding Discontinued Operations Disclosure [TextBlock]	Note 5 — Assets Sold and Planned Dispositions Assets Sold On April 15, 2019, we completed the sale of our 30 percent interest in Greater Sunrise Fields to the government of Timor-Leste for $ 350 million before customary adjustments and will recognize an after-tax gain of approximately $ 50 million in the second quarter. The Greater Sunrise Fields are included in our Asia Pacific and Middle East segment. Planned Dispositions In January 2019, we entered into agreements to sell our 12.4 percent ownership interests in the Golden Pass LNG Terminal and Golden Pass Pipeline. We have also entered into agreements to amend our contractual obligations for retaining use of the facilities. As a result of entering into these agreements, we recorded a before-tax impairment of $ 60 million in the first quarter of 2019 which is included in the “Equity in earning s of affiliates” line on our consolidated income statement . The transaction is subject to regulatory approval. Both ownership interests are accounted for as equity affiliates in our Lower 48 segment. See Note 14 — Fair Value Measurement for additional i nformation. In April 2019, we entered into an agreement to sell two ConocoPhillips U.K. subsidiaries to Chrysaor E&P Limited for $ 2.675 billion plus interest and customary adjustments. Together the subsidiaries indirectly hold the company’s exploration and production assets in the U . K. As of March 31, 2019, the net carrying value was approximately $ 0. 8 billion, with $ 1.6 billion of PP&E , $ 0. 5 billion of working capital , $ 0. 4 billion of cumulative foreign currency translation adjustments , and deferred tax assets of $ 0.3 billion , offset by $ 2.0 billion of ARO . As part of the transaction, we expect to recognize a U.S. tax benefit of $ 0.2 billion in the second quarte r of 2019 related to a previously unrecognizable U.S. tax basis in the subsidiaries to be sold. Depending on the timing of regulatory approval and other specific conditions precedent , we anticipate recognizing a gain of approximately $ 2 billion before- and after-tax on completion of the sale in the second half of 2019 , subject to customary adjustments and foreign exchange impacts . The subsidiaries met held for sale criteria in April 2019. Results of operations for the U . K . are reported within our Europe and North Africa segment.

Investments, Loans and Long-Term Receivables	Note 6 —Investments, Loans and Long-Term Receivables APLNG APLNG executed project financing agreements for an $ 8.5 billion project finance facility in 2012. The $ 8.5 billion project finance facility was initially composed of financing agreements executed by APLNG with the Export-Import Bank of the United States for approximately $ 2.9 billion, the Export-Import Bank of China for approximately $ 2.7 billi on, and a syndicate of Australian and international commercial banks for approximately $ 2.9 billion. All amounts have been drawn from the facility. APLNG made its first principal and interest repayment in March 2017 and is scheduled to make b i-annual payments until March 2029. APLNG made a voluntary repayment of $ 1.4 billion to the Export-Import Bank of China in September 2018. At the same time, APLNG obtained a United States Private Placement (USPP) bond facility of $ 1.4 billion. APLNG made its first i nterest payment in March 2019 , and principal payments are scheduled to commence in September 2023, with bi-annual payments due on the facility until September 2030. During the first quarter of 2019, APLNG ref inanced $ 3.2 billion of existing project finance debt through two transactions. As a result of the first transaction, APLNG o btained a commercial bank facility of $ 2.6 billion. Interest and principal payments are scheduled to comm ence in September 2019, with bi-annual payments due on the facility until March 2028.

Interest payments are scheduled to commence in September 2019 , and principal payments are scheduled to commence in September 2023, with bi-annual payments due on the facility until September 2030. In conjunction with the $ 3.2 billion debt obtained during the first quarter of 2019 to refinance existing project finance debt, APLNG made voluntary repayments of $ 2.2 billion and $ 1.0 billion to a syndicate of Australian and international commercial banks and the Export-Import Bank of China, respectively. At March 31, 2019 , a balance of $ 7.0 billion was outstanding on the facilities. See Note 11 — Guarantees, for additional information.

Guarantees

Guarantees	Mar. 31, 2019
Guarantees [Abstract]
Guarantees	Note 11 —Guarantees At March 31, 2019 , we were liable for certain contingent obligations under various contractual arrangements as described below. We recognize a liability, at inception, for the fair value of our obligation as a guarantor for newly issued or modified guarantees. Unless the carrying amount of the liability is noted below, we have not recognized a liability because the fair value of the obligation is immaterial. In addition, unless otherwise stated, we are not currently performing with any significance under the guarantee an d expect future performance to be either immaterial or have only a remote chance of occurrence. APLNG Guarantees At March 31, 2019 , we had outstanding multiple guarantees in connection with our 37.5 percent ownership interest in APLNG. The following is a d escription of the guarantees with values calculated utilizing March 2019 exchange rates: During the third quarter of 2016, we issued a guarantee to facilitate the withdrawal of our pro-rata portion of the funds in a project finance reserve account. We estimate the remaining term of this guarantee is 12 years . Our maximum exposure under this guarantee is approximately $ 170 million and may become payable if an enforcement action is commenced by the project finance lenders against APLNG. At March 31, 2019 , the carrying value of this guarantee is approximately $ 14 million. In conjunction with our original purchase of an ownership interest in APLNG from Origin Energy in October 2008, we agreed to reimburse Origin Energy for our share of the existing contingent liability arising under guarantees of an existing obligation of APLNG to deliver natural gas under several sales agreements with remaining terms of up to 23 years . Our maximum pote ntial liability for future payments, or cost of volume delivery, under these guarantees is estimated to be $ 800 million ($ 1.4 billion in the event of intentional or reckless breach) and would become payable if APLNG fails to meet its obligations under thes e agreements and the obligations cannot otherwise be mitigated. Future payments are considered unlikely, as the payments, or cost of volume delivery, would only be triggered if APLNG does not have enough natural gas to meet these sales commitments and if the co-venturers do not make necessary equity contributions into APLNG. We have guaranteed the performance of APLNG with regard to certain other contracts executed in connection with the project’s continued development. The guarantees have remaining ter ms of up to 27 years or the life of the venture. Our maximum potential amount of future payments related to these guarantees is approximately $ 140 million and would become payable if APLNG does not perform. Other Guarantees We have other guarantees with maximum future potential payment amounts totaling approximately $ 780 million, which consist primarily of guarantees of the residual value of leased office buildings, guarantees of the residual value of corporate aircraft, and a guarantee for our por tion of a joint venture’s project finance reserve accounts. These guarantees have remaining terms of up to four years and would become payable if, upon sale, certain asset values are lower than guaranteed amounts, business conditions decline at guaranteed entities, or as a result of nonperformance of contractual terms by guaranteed parties. Indemnifications Over the years, we have entered into agreements to sell ownership interests in certain corporations, joint ventures and assets that gave rise to qua lifying indemnifications. These agreements include indemnifications for taxes, environmental liabilities, employee claims and litigation. The terms of these indemnifications vary greatly. The majority of these indemnifications are related to environment al issues, the term is generally indefinite and the maximum amount of future payments is generally unlimited. The carrying amount recorded for these indemnifications at March 31, 2019 , was approximately $ 90 million. We amortize the indemnification liabilit y over the relevant time period, if one exists, based on the facts and circumstances surrounding each type of indemnity. In cases where the indemnification term is indefinite, we will reverse the liability when we have information the liability is essenti ally relieved or amortize the liability over an appropriate time period as the fair value of our indemnification exposure declines. Although it is reasonably possible future payments may exceed amounts recorded, due to the nature of the indemnifications, it is not possible to make a reasonable estimate of the maximum potential amount of future payments. Included in the recorded carrying amount at March 31, 2019 , were approximately $ 30 million of environmental accruals for known contamination that are includ ed in the “Asset retirement obligations and accrued environmental costs” line on our consolidated balance sheet. For additional information about environmental liabilities, see Note 12 —Contingencies and Commitments.

Contingencies and Commitments

Contingencies and Commitments	3 Months Ended
Contingencies and Commitments	Mar. 31, 2019
Contingencies and Commitments [Abstract]
Contingencies and Commitments	Note 12 —Contingencies and Commitments A number of lawsuits involving a variety of claims arising in the ordinary course of business have been filed against ConocoPhillips. We also may be required to remove or mitigate the effects on the environment of the placement, storage, disposal or release of certain chemical, mineral and petroleum substances at various active and inactive sites. We regularly assess the need for accounting recognition or disclosure of these contingencies. In the ca se of all known contingencies (other than those related to income taxes), we accrue a liability when the loss is probable and the amount is reasonably estimable. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not reduce these liabilities for potential insurance or third-party recoveries. If applicable, we accrue receivables for probable insurance or other third-party recoveries. With respect to income tax-related contingencies, we use a cumulative probability-weighted loss accrual in cases where sustaining a tax position is less than certain. Based on currently available information, we believe it is remote that future costs rela ted to known contingent liability exposures will exceed current accruals by an amount that would have a material adverse impact on our consolidated financial statements. As we learn new facts concerning contingencies, we reassess our position both with re spect to accrued liabilities and other potential exposures. Estimates particularly sensitive to future changes include contingent liabilities recorded for environmental remediation, tax and legal matters. Estimated future environmental remediation costs are subject to change due to such factors as the uncertain magnitude of cleanup costs, the unknown time and extent of such remedial actions that may be required, and the determination of our liability in proportion to that of other responsible parties. Es timated future costs related to tax and legal matters are subject to change as events evolve and as additional information becomes available during the administrative and litigation processes. Environmental We are subject to international, federal, state and local environmental laws and regulations. When we prepare our consolidated financial statements, we record accruals for environmental liabilities based on management’s best estimates, using all information that is available at the time. We measure estimates and base liabilities on currently available facts, existing technology, and presently enacted laws and regulations, taking into account stakeholder and business considera tions. When measuring environmental liabilities, we also consider our prior experience in remediation of contaminated sites, other companies’ cleanup experience, and data released by the U.S. EPA or other organizations. We consider unasserted claims in o ur determination of environmental liabilities, and we accrue them in the period they are both probable and reasonably estimable. Although liability of those potentially responsible for environmental remediation costs is generally joint and several for fed eral sites and frequently so for other sites, we are usually only one of many companies cited at a particular site. Due to the joint and several liabilities, we could be responsible for all cleanup costs related to any site at which we have been designate d as a potentially responsible party. We have been successful to date in sharing cleanup costs with other financially sound companies. Many of the sites at which we are potentially responsible are still under investigation by the EPA or the agency concer ned. Prior to actual cleanup, those potentially responsible normally assess the site conditions, apportion responsibility and determine the appropriate remediation. In some instances, we may have no liability or may attain a settlement of liability. Whe re it appears that other potentially responsible parties may be financially unable to bear their proportional share, we consider this inability in estimating our potential liability, and we adjust our accruals accordingly. As a result of various acquisiti ons in the past, we assumed certain environmental obligations. Some of these environmental obligations are mitigated by indemnifications made by others for our benefit, and some of the indemnifications are subject to dollar limits and time limits. We are currently participating in environmental assessments and cleanups at numerous federal Superfund and comparable state and international sites. After an assessment of environmental exposures for cleanup and other costs, we make accruals on an undiscounted basis (except those acquired in a purchase business combination, which we record on a discounted basis) for planned investigation and remediation activities for sites where it is probable future costs will be incurred and these costs can be reasonably esti mated. We have not reduced these accruals for possible insurance recoveries. At March 31, 2019 , our consolidated balance sheet included a total environmental accrual of $ 176 million, compared with $ 178 million at December 31, 2018 , for remediation activities in the United States and Canada. We expect to incur a substantial amount of these expenditures within the next 30 years . In the future, we may be involved in additional environmental assessments, cleanups and pr oceedings. Legal Proceedings We are subject to various lawsuits and claims including but not limited to matters involving oil and gas royalty and severance tax payments, gas measurement and valuation methods, contract disputes, environmental damages, personal injury, and property damage. Our primary exposures for such matters relate to alleged royalty and tax underpayments on certain federal, state and privately owned properties and claims of alleged environmental contamination from historic operations. We will conti nue to defend ourselves vigorously in these matters. Our legal organization applies its knowledge, experience and professional judgment to the specific characteristics of our cases, employing a litigation management process to manage and monitor the legal proceedings against us. Our process facilitates the early evaluation and quantification of potential exposures in individual cases. This process also enables us to track those cases that have been scheduled for trial and/or mediation. Based on professi onal judgment and experience in using these litigation management tools and available information about current developments in all our cases, our legal organization regularly assesses the adequacy of current accruals and determines if adjustment of existi ng accruals, or establishment of new accruals, is required. Other Contingencies We have contingent liabilities resulting from throughput agreements with pipeline and processing companies not associated with financing arrangements. Under these agreements, we may be required to provide any such company with additional funds through adv ances and penalties for fees related to throughput capacity not utilized. In addition, at March 31, 2019 , we had performance obligations secured by letters of credit of $ 274 million (issued as direct bank letters of credit) related to various purchas e commitments for materials, supplies, commercial activities and services incident to the ordinary conduct of business. In 2007, ConocoPhillips was unable to reach agreement with respect to the empresa mixta structure mandated by the Venezuelan governmen t’s Nationalization Decree. As a result, Venezuela’s national oil company, Petróleos de Venezuela, S.A. (PDVSA), or its affiliates, directly assumed control over ConocoPhillips’ interests in the Petrozuata and Hamaca heavy oil ventures and the offshore Co rocoro development project. In response to this expropriation, ConocoPhillips initiated international arbitration on November 2, 2007, with the ICSID. On September 3, 2013, an ICSID arbitration tribunal held that Venezuela unlawfully expropriated ConocoP hillips’ significant oil investments in June 2007. On January 17, 2017, the Tribunal reconfirmed the decision that the expropriation was unlawful. In March 2019, the Tribunal unanimously ordered the government of Venezuela to pay ConocoPhillips $ 8.7 billion in compensation for the government’s unlawful expropriation of the company’s investments in Venezuela in 2007 . ConocoPhillips has filed a request for recognition of the Award in several jurisdictions. An Application for Rectification of the Award requesting correction of certain calculations was filed on behalf of the government of Venezuela, which the ICSID Tribunal is now reviewing. Once resolved, the government of Venezuela may then seek annulment of the Award . In 2014, ConocoPhi llips filed a separate and independent arbitration under the rules of the ICC against PDVSA under the contracts that had established the Petrozuata and Hamaca projects. The ICC Tribunal issued an award in April 2018, finding that PDVSA owed ConocoPhillips approximately $ 2 billion under their agreements in connection with the expropriation of the projects and other pre-expropriation fiscal measures. In August 2018, ConocoPhillips entered into a settlement with PDVSA to recover the full a mount of this ICC award, plus interest through the payment period, including initial payments totaling approximately $ 500 million within a period of 90 days from the time of signing of the settlement agreement. The balance of the settleme nt is to be paid quarterly over a period of four and a half years. To date, PDVSA has fully complied with the terms of this settlement agreement . Per the settlement, PDVSA recognized the ICC award as a judgment in various jurisdictions, and ConocoPhillips agreed to suspend its legal enforcement actions. ConocoPhillips has ensured that the settlement meets all appropriate U.S. regulatory requirements, including any applicable sanctions imposed by the U.S. against Venezuela. In 2016, ConocoPhillips filed a separate and independent arbitration under the rules of the ICC against PDVSA under the contracts that had established the Corocoro project. This ICC arbitration is currently in progress. In February 2017, the ICSID T ribunal unanim ously awarded Burlington Resources, Inc., a wholly owned subsidiary of ConocoPhillips, $ 380 million for Ecuador’s unlawful expropriation of Burlington’s investment in Blocks 7 and 21, in breach of the U.S.-Ecuador Bilateral Investment Treaty. The tribunal also issued a separate decision finding Ecuador to be entitled to $ 42 million for environmental and infrastructure counterclaims. In December 2017, Burlington and Ecuador entered into a settlement agreement by which Ecu ador paid Burlington $ 337 million in two installments. The first installment of $ 75 million was paid in December 2017, and the second installment of $ 262 million was paid in April 2018. The settlement i ncluded an offset for the counterclaims decision, of which Burlington is entitled to a $ 24 million contribution from Perenco Ecuador Limited, its co-venturer and consortium operator, pursuant to a joint and several liability provision in the JOA. Ecuador’s environmental and infrastructure counterclaims against Perenco remain pending in a separate ICSID arbitration between Perenco and Ecuador, and Burlington may owe Perenco a contribution under the JOA for damages found by this tribunal . In June 2017, FAR Ltd. initiated arbitration before the ICC against ConocoPhillips Senegal B.V. , now Woodside Senegal B.V., in connection with the sale of ConocoPhillips Senegal B.V. to Woodside Energy Holdings (Senegal) Limited in 2016. This arbitrati on is ongoing. In late 2017, ConocoPhillips (U.K.) Limited (CPUKL) initiated United Nations Commission on International Trade and Law (UNCITRAL) arbitration against Vietnam in accordance with the U.K.-Vietnam Bilateral Investment Treaty relating to a tax dispute arising from the 2012 sale of ConocoPhillips (U.K.) Cuu Long Limited and ConocoPhillips (U.K.) Gama Limited. The tribunal was constituted in February 2018. The arbitration is ongoing. In 2017 and 2018, cities, counties, and a state government in California, New York, Washington, Rhode Island and Maryland, as well as the Pacific Coast Federation of Fishermen’s Association, Inc., have filed lawsuits against oil and gas companies, including ConocoPhillips, seeking compensatory damages and equitable relief to abate alleged climate change impacts. ConocoPhillips is vigorously defending against these lawsuits. The lawsuits brought by the Cities of San Francisco, Oakland and New York have been dismissed by the district courts and appeals are pending. S everal Louisiana parishes and individual landowners have filed lawsuits against oil and gas companies, including ConocoPhillips, seeking compensatory damages in connection with historical oil and gas operations in Louisiana. ConocoPhillips will vigorousl y defend against these lawsuits .

Where these balances have the right of setoff, they are presented on a net basis. Related cash flows are recorded as operating activities on our consolidated statement of cash flows. On our consolidated income statement, realized and unrealized gains and losses are recognized either on a gross basis if directly related to our physical business or a net basis if held for trading.

Financial Instruments We invest excess cash in financial instruments with maturities based on our cash forecasts for the various currency pools we manage. The maturities of these investments may from time to time extend beyond 90 days. The types of financial instruments that we currently invest include: Time deposits: Interest bearing deposits placed with approved financial institutions. Commercial paper: Unsecured promissory notes issued by a corporation, commercial bank or government agency purchased at a discount to mature at par. Government or government agency obligations: Short-term securities issued by the U.S. government or U.S. government agencies. These financial instruments appear in the “Cash and cash equivalents” line of our consolidated balance sheet if the maturities at the time we made the investments were 90 days or less; otherwise, these financial instruments are included in the “S hort-term investments” line on our consolidated balance sheet .

Our cash equivalents and short-term investments are placed in high-quality commercial paper, government money market funds, government debt securities and time deposits with major international banks and financial institutions. The credit risk from our OTC derivative contracts, such as fo rwards, swaps and options, derives from the counterparty to the transaction. Individual counterparty exposure is managed within predetermined credit limits and includes the use of cash-call margins when appropriate, thereby reducing the risk of significan t nonperformance. We also use futures, swaps and option contracts that have a negligible credit risk because these trades are cleared with an exchange clearinghouse and subject to mandatory margin requirements until settled; however, we are exposed to the credit risk of those exchange brokers for receivables arising from daily margin cash calls, as well as for cash deposited to meet initial margin requirements. Our trade receivables result primarily from our petroleum operations and reflect a broad natio nal and international customer base, which limits our exposure to concentrations of credit risk. The majority of these receivables have payment terms of 30 days or less , and we continually monitor this exposure and the creditworthiness of the counterparti es. We do not generally require collateral to limit the exposure to loss; however, we will sometimes use letters of credit, prepayments and master netting arrangements to mitigate credit risk with counterparties that both buy from and sell to us, as these agreements permit the amounts owed by us or owed to others to be offset against amounts due to us. Certain of our derivative instruments contain provisions that require us to post collateral if the derivative exposure exceeds a threshold amount. We have contracts with fixed threshold amounts and other contracts with variable threshold amounts that are contingent on our credit rating. The variable threshold amounts typically decline for lower credit ratings, while both the variable and fixed threshold am ounts typically revert to zero if we fall below investment grade. Cash is the primary collateral in all contracts; however, many also permit us to post letters of credit as collateral, such as transactions administered through the New York Mercantile Exch ange. The aggregate fair value of all derivative instruments with such credit risk-related contingent features that were in a liability position on March 31, 2019 and December 31, 2018 , was $ 50 million and $ 62 million, respectively. For these instr uments , no collateral was posted as of March 31, or December 31, 2018 . If our credit rating had been downgraded below investment grade on March 31, 2019 , we would be required to post $ 50 million of additional collateral, either with cash or letters of credit.

Fair Value Measurement

Fair Value Measurement	3 Months Ended
Fair Value Measurement	Mar. 31, 2019
Fair Value Measurement [Abstract]
Fair Value Measurement	Note 14 —Fair Value Measurement We carry a portion of our assets and liabilities at fair value that are measured at a reporting date using an exit price (i.e., the price that would be received to sell an asset or paid to transfer a liability) and disclosed according to the quality of valuation inputs under the following hierarchy: Level 1: Quoted prices (unadjusted) in an active market for identical assets or liabilities. Level 2: Inputs other than quoted prices that are directly or indirectly observable. Level 3: Unobservable inputs that are significant to the fair value of assets or liabilities. The classification of an asset or liability is based on the lowest level of input significant to its fair value. Those that are initiall y classified as Level 3 are subsequently reported as Level 2 when the fair value derived from unobservable inputs is inconsequential to the overall fair value, or if corroborated market data becomes available. Assets and liabilities initially reported as Level 2 are subsequently reported as Level 3 if corroborated market data is no longer available. Transfers occur at the end of the reporting period. There were no material transfers between levels during 2019 or 2018 . Recur ring Fair Value Measurement Financial assets and liabilities reported at fair value on a recurring basis primarily include our investment in Cenovus Energy shares and commodity derivatives. Level 1 derivative assets and liabilities primarily represent exchange-traded futures and options that are valued using unadjusted prices available from the underlying exchange. Level 1 also includes our investment in common shares of Cenovus Energy, which is valued using quotes for shares on the New York Stock Exchange. Level 2 derivative assets and liabilities primarily represent OTC swaps, options and forward purchase and sale contracts that are valued using adjusted exchange prices, prices provided by brokers or pricing service companies that are all corroborated by market data. Level 3 derivative assets and liabilities consist of OTC swaps, options and forward purchase and sale contracts where a significant portion of fair value is calculated from underlying market data that is not readily available.

The fair value s were determined by negotiated selling prices. For additional information, see Note 5 — Assets Sold and Planned Dispositions Reported Fair Values of Financial Instruments We used the following methods and assumptions to estimate the fair value of financial instruments: Cash and cash equivalents and short-term investments: The carrying amount reported on our consolidated balance sheet approximates fair value. Accounts and notes receivable (including long-term and related parties): The carrying amount reported on our consolidated balance sheet approximates fair value. The valuation technique and methods used t o estimate the fair value of the current portion of fixed-rate related party loans is consistent with Loans and advances—related parties. Investment in Cenovus Energy shares: See Note 7 —Investment in Cenovus Energy for a discussion of the carrying val ue and fair value of our investment in Cenovus Energy shares. Loans and advances—related parties: The carrying amount of floating-rate loans approximates fair value. The fair value of fixed-rate loan activity is measured using market observable data and is categorized as Level 2 in the fair value hierarchy. See Note 6 —Investments, Loans and Long-Term Receivables for additional information. Accounts payable (including related parties) and floating-rate debt: The carrying amount of accounts payable an d floating-rate debt reported on our consolidated balance sheet approximates fair value. Fixed-rate debt: The estimated fair value of fixed-rate debt is measured using prices available from a pricing service that is corroborated by market data; therefore , these liabilities are categorized as Level 2 in the fair value hierarchy.

Leases [Abstract]
Leases of Lessee Disclosure [Text Block]	Note 15 — Non-Mineral Leases The company primarily leases office buildings and drilling equipment, as well as ocean transport vessels, tugboats, corporate aircraft, and other facilities and equipment. Certain leases include escalation clauses for adjusting rental payments to reflect changes in price indices and other leases include payment provisions that vary based on the nature of usage of the leased asset. Additionally, the company has executed certain leases that provide it with the option to extend or renew the term of the lease , terminate the lease prior to the end of the lease term, or purchase the leased asset as of the end of the lease term. In other cases, the company has executed lease agreements that require it to guarantee the residual value of certain leased office buil dings. For additional information about guarantees, see Note 11 —Guarantees. There are no significant restrictions imposed on us by the lease agreements with regard to dividends, asset dispositions or borrowing ability. Certain arrangements may conta in both lease and non-lease components and we determine if an arrangement is or contains a lease at contract inception. Only the lease components of these contractual arrangements are subject to the provisions of ASC Topic 842, and any non-lease component s are subject to other applicable accounting guidance; however, we have elected to adopt the optional practical expedient not to separate lease components apart from non-lease components for accounting purposes. This policy election has been adopted for e ach of the company’s leased asset classes existing as of the effective date and subject to the transition provisions of ASC Topic 842 and will be applied to all new or modified leases executed on or after January 1, 2019. For contractual arrangements exec uted in subsequent periods involving a new leased asset class, the company will determine at contract inception whether it will apply the optional practical expedient to the new leased asset class. Leases are evaluated for classification as operating or finance leases at the commencement date of the lease and right-of-use assets and corresponding liabilities are recognized on our consolidated balance sheet based on the present value of future lease payments relating to the use of the underlying asset duri ng the lease term. Future lease payments include variable lease payments that depend upon an index or rate using the index or rate at the commencement date and probable amounts owed under residual value guarantees. The amount of future lease payments may be increased to include additional payments related to lease extension, termination, and/or purchase options when the company has determined, at or subsequent to lease commencement, generally due to limited asset availability or operating commitments, it is reasonably certain of exercising such options. We use our incremental borrowing rate as the discount rate in determining the present value of future lease payments, unless the interest rate implicit in the lease arrangement is readily determinable. Le ase payments that vary subsequent to the commencement date based on future usage levels, the nature of leased asset activities, or certain other contingencies are not included in the measurement of lease right-of-use assets and corresponding liabilities. We have elected not to record assets and liabilities on our consolidated balance sheet for lease arrangements with terms of 12 months or less. We often enter into leasing arrangements acting in the capacity as operator for and/or on behalf of certain oil and gas joint ventures of undivided interests. If the lease arrangement can be legally enforced only against us as operator and there is no separate arrangement to sublease the underlying leased asset to our coventurers, we recognize at lease commenceme nt a right-of-use asset and corresponding lease liability on our consolidated balance sheet on a gross basis. While we record lease costs on a gross basis in our consolidated income statement and statement of cash flows, such costs are offset by the reimb ursement we receive from our coventurers for their share of the lease cost as the underlying leased asset is utilized in joint venture activities. As a result, lease cost is presented in our consolidated income statement and statement of cash flows on a p roportional basis. If we are a nonoperating coventurer, we recognize a right-of-use asset and corresponding lease liability only if we were a specified contractual party to the lease arrangement and the arrangement could be legally enforced against us. I n this circumstance, we would recognize both the right-of-use asset and corresponding lease liability on our consolidated balance sheet on a proportional basis consistent with our undivided interest ownership in the related joint venture. The company has h istorically reco rded certain finance leases executed by investee companies accounted for under the proportionate consolidation method of accounting on its consolidated balance sheet on a proportional basis consistent with its ownership interest in the inve stee company. In addition, the company has historically recorded finance lease assets and liabilities associated with certain oil and gas joint ventures on a proportional basis pursuant to accounting guidance applicable prior to January 1, 2019. As of De cember 31, 2018, $ 420 million of finance lease assets (net of accumulated depreciation, depletion and amortization) and $ 688 million of finance lease liabilities were recorded on our consolidated balance sheet associated with these leases. In accordance w ith the transition provisions of ASC Topic 842, and since we have elected to adopt the package of optional transition-related practical expedients, the historical accounting treatment for these leases has been carried forward and is subject to reconsiderat ion upon the modification or other required reassessment of the arrangements prior to lease term expiration. In connection with our adoption of ASC Topic 842, we have recorded on our consolidated balance sheet $ 57 million of operating leases executed by investee companies accounted for under the proportionate consolidation method of accounting on a proportional basis consistent with our ownership interest in the investee company. The following tables sum marize the finance leases amounts that were reflected on our consolidated balance sheet as of December 31, 2018, the operating leases impact of adopting ASC Topic 842, and the right-of-use asset and lease liability balances reflected for both operating and finance leases on our consolidated balance sheet as of March 31, 2019: Millions of Dollars Carrying Amount Operating Leases Finance Leases Amounts recognized in line items in our Consolidated Balance Sheet upon adoption of ASC Topic 842 Right-of-Use Assets Properties, plants and equipment Gross $ 1,044 Accumulated depreciation, depletion and amortization (550) Net properties, plants and equipment as of December 31, 2018 $ 494 Adoption of ASC Topic 842 as of January 1, 2019 $ 998 Lease Liabilities Short-term debt $ 79 Long-term debt 698 Total finance leases debt as of December 31, 2018 $ 777 Adoption of ASC Topic 842 as of January 1, 2019 $ 998 Amounts recognized in line items in our Consolidated Balance Sheet at March 31, 2019 Right-of-Use Assets Properties, plants and equipment Gross $ 1,044 Accumulated depreciation, depletion and amortization (579) Net properties, plants and equipment * $ 465 Other assets $ 981 Includes proportionately consolidated finance lease assets (net of accumulated depreciation, depletion and amortization) of $ 398 million.

There is no significant difference in contractual terms or the policy for recognition of revenue from these contracts and those within the scope of ASC Topic 606. The following disaggregation of revenues is provided in conjunction with Note 21 — Segment Disclosures and Related Information : Millions of Dollars Three Months Ended March 31 2019 2018 Revenue from Contracts Outside the Scope of ASC Topic 606 by Segment Lower 48 $ 1,613 1,713 Canada 241 191 Europe and North Africa 227 357 Physical contracts meeting the definition of a derivative $ 2,081 2,261 Millions of Dollars Three Months Ended March 31 2019 2018 Revenue from Contracts Outside the Scope of ASC Topic 606 by Product Crude oil $ 188 286 Natural gas 1,768 1,890 Other 125 85 Physical contracts meeting the definition of a derivative $ 2,081 2,261 Practical Expedients Typically, our commodity sales contracts are less than 12 months in duration; however, in certain specific cases may extend longer, which may be out to the end of field life. We have long-term commodity sales contracts which use prevailing market prices a t the time of delivery, and under these contracts, the market-based variable consideration for each performance obligation (i.e., delivery of commodity) is allocated to each wholly unsatisfied performance obligation within the contract. Accordingly, we ha ve applied the practical expedient allowed in ASC Topic 606 and do not disclose the aggregate amount of the transaction price allocated to performance obligations or when we expect to recognize revenues that are unsatisfied (or partially unsatisfied) as of the end of the reporting period. Receivables and Contract Liabilities Receivables from Contracts with Customers At March 31, 2019 , the “ Accounts and n otes receivable ” line on our consolidated balance sheet , includes trade receivables of $ 2,638 million compared with $ 2,889 million at December 31, 201 8 , and includes both contracts with customers within the scope of ASC Topic 606 and those that are outside the scope of ASC Topic 606. We typically receive payment within 30 days or less (depending on the terms of the invoice) once delivery is made . Revenues that are outside the scope of ASC Topic 606 relate primarily to physical gas sales contracts at market prices for which we do not elect NPNS and are therefore accounted for as a derivative under ASC Topic 815. There is lit tle distinction in the nature of the customer or credit quality of trade receivables associated with gas sold under contracts for which NPNS has not been elected compared to trade receivables where NP NS has been elected. Contract Liabilities from Contracts with Customers We have entered into contractual arrangements where we license proprietary technology to customers related to the optimization process for operating LNG plants. The agreements typically provide for negotiated payments to be made a t stated milestones. The payments are not directly related to our performance under the contract and are recorded as deferred revenue to be recognized as revenue when the customer can utilize and benefit from their right to use the license. Payments are received in instal l ments over the construction period.

Income Taxes	Note 22 —Income Taxes Our effective tax rate for the first quarter of 2019 was 31 percent compared with 49 percent for the first quarter of 2018 . The effective tax rate for first quarter 2019 is lower than the effective tax rate for 2018 primarily due to higher before-tax income in lower tax jurisdictions for 2019 as well as a reduction of our U.S. valuation allowance for the first quarter of 2019. During the first quarter of 2019, our U.S. valuation allowance decreased by $ 103 million compared to an increase of $ 57 million for the first quarter of 2018. The change to our U.S. valuation allowance for both periods relates primarily to the fair value measuremen t of our Cenovus Energy common shares.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The interim-period financial information presented in the financial statements included in this report is unaudited and, in the opinion of management, includes all known accruals and adjustments necessary for a fair presentation of the consolidated financial position of ConocoPhillips and its results of operations and cash flows for such periods. All such adjustments are of a normal and recurring nature unless otherwise disclosed. Certain notes and other information have been condensed or omitted from the interim financial statements included in this report. Therefore, these financial statements should be read in conjunction with the consolidated financial statements and notes included in our 2018 Annual Report on Form 10-K.
New Accounting Pronouncements, Policy [Policy Text Block]	Note 2 — Changes in Accounting Principles We adopted the provisions of FASB ASU No. 2016-02, “Leases,” and its amendments set forth by the provisions of ASU No. 2018-01, “Land Easement Practical Expedient for Transition to Topic 842,” ASU No. 2018-10, “Codification Improvements to Topic 842, Leases,” ASU No. 2018-11, “Targeted Improv ements,” ASU No. 2018-20, “Narrow-Scope Improvements for Lessors,” and ASU No. 2019-01, “Codification Improvements,” collectively FASB ASC Topic 842, “Leases” (ASC Topic 842), beginning January 1, 2019 . ASC Topic 842 establishes comprehensive accounting and financial reporting requirements for leasing arrangements, supersedes the existing requirements in FASB ASC Topic 840, “Leases” (ASC Topic 840), and requires lessees to recognize substantially all lease assets and lease liabilities on the balance sheet . The provisions of ASC Topic 842 also modify the definition of a lease and outline requirements for recognition, measurement, presentation and disclosure of leasing arrangements by both lessees and lessors. We adopted ASC Topic 842 using the modifie d retrospective approach and elected to utilize the Optional Transition Method, which permits us to apply the provisions of ASC Topic 842 to leasing arrangements existing at or entered into after January 1, 2019, and present in our financial statements com parative periods prior to January 1, 2019 under the historical requirements of ASC Topic 840. In addition, we elected to adopt the package of optional transition-related practical expedients , which among other things, allows us to carry forward certain hi storical conclusions reached under ASC Topic 840 regarding lease identification, classification, and the accounting treatment of initial direct costs. Furthermore, we elected not to record assets and liabilities on our consolidated balance sheet for new o r existing lease arrangements with terms of 12 months or less. The primary impact of applying ASC Topic 842 is the initial recognition of $ 998 m illion of lease liabilities and corresponding right-of-use assets on our consolidated balance sh eet as of January 1, 2019, for leases classified as operating leases under ASC Topic 840, as well as enhanced disclosure of our leasing arrangements. Our accounting treatment for finance leases remains unchanged. In addition, there is no cumulative effec t to retained earnings or other components of equity recognized as of January 1, 2019, and the adoption of ASC Topic 842 did not impact the presentation of our consolidated income statement or statement of cash flows. See Note 15 —Non-Mineral Leases for additional information related to the adoption of ASC Topic 842 . We adopted the provisions of FASB ASU No. 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income , ” beginning January 1, 2019. The ASU allows a reclass ification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act, eliminating the stranded tax effects. The cumulative effect to our consolidated balance sheet at January 1, 2019 for the adoption of ASU No. 2018-02 w as as follows

Lease, Practical Expedients, Package [true false]	true
Practical Expedient, Lessor Single Lease Component [true false]	true
Revenue Recognition, Policy [Policy Text Block]	Practical Expedients Typically, our commodity sales contracts are less than 12 months in duration; however, in certain specific cases may extend longer, which may be out to the end of field life. We have long-term commodity sales contracts which use prevailing market prices a t the time of delivery, and under these contracts, the market-based variable consideration for each performance obligation (i.e., delivery of commodity) is allocated to each wholly unsatisfied performance obligation within the contract. Accordingly, we ha ve applied the practical expedient allowed in ASC Topic 606 and do not disclose the aggregate amount of the transaction price allocated to performance obligations or when we expect to recognize revenues that are unsatisfied (or partially unsatisfied) as of the end of the reporting period.

Practical Expedient	true
Revenue, Practical Expedient, Remaining Performance Obligation, Description	Typically, our commodity sales contracts are less than 12 months in duration; however, in certain specific cases may extend longer, which may be out to the end of field life. We have long-term commodity sales contracts which use prevailing market prices at the time of delivery, and under these contracts, the market-based variable consideration for each performance obligation (i.e., delivery of commodity) is allocated to each wholly unsatisfied performance obligation within the contract. Accordingly, we have applied the practical expedient allowed in ASC Topic 606 and do not disclose the aggregate amount of the transaction price allocated to performance obligations or when we expect to recognize revenues that are unsatisfied (or partially unsatisfied) as of the end of the reporting period.
