New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Significant Accounting Policies [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 Improvements,” 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 modified 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 comparative 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 historical 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 or existing lease arrangements with terms of 12 months or less. The primary impact of applying ASC Topic 842 is the initial recognition of $ 998 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 reclassification 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 was 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 (VIE

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 Petrochemical 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 CBM, as well as LNG processing and export marketing. As a result, we do not consolidate APLNG, and it is accounted for as an equity method investment. As of September 30, 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 (MWCC) 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 deployable 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. MWCC is considered 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 company and to undertake certain obligations that most significantly impact its economic performance with nine other unaffiliated owners of MWCC. Based on inputs related to the fair value of MWCC observed in the second quarter of 2019, we reduced the carrying value of our equity method investment in MWCC to $ 30 million and recorded a before-tax impairment of $ 95 million which is included in the “Equity in earnings of affiliates” line on our consolidated income statement. For additional information see Note 14—Fair Value Measurement. At September 30, 2019, the carrying value of our equity method investment in MWCC was $ 27 million. We have not provided 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 Group Excluding Discontinued Operation Additional Disclosures [Abstract]
Long Lived Assets Held For Sale [Text Block]	Note 5—Asset Dispositions Asset Dispositions 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, with an effective date of January 1, 2018. On September 30, 2019, we completed the sale for proceeds of $ 2.2 billion. In the nine-month period of 2019, we recorded a $ 1.8 billion before-tax and $ 2.1 billion after-tax gain associated with this transaction. Together the subsidiaries sold indirectly held our exploration and production assets in the U.K. At the time of disposition, the net carrying value was approximately $ 0.4 billion, consisting primarily of $ 1.6 billion of PP&E, $ 0.5 billion of cumulative foreign currency translation adjustments, and $ 0.2 billion of deferred tax assets, offset by $ 1.8 billion of ARO and negative $ 0.1 billion of working capital. The before-tax earnings associated with the subsidiaries sold were $ 0.6 billion and $ 0.4 billion for the nine-month periods of 2018 and 2019, respectively. Results of operations for the U.K. are reported within our Europe and North Africa segment. In the second quarter of 2019, we recognized an after-tax gain of $ 52 million upon the closing of the sale of our 30 percent interest in the Greater Sunrise Fields to the government of Timor-Leste for $ 350 million. The Greater Sunrise Fields were included in our Asia Pacific and Middle East segment. 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 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 earnings of affiliates” line on our consolidated income statement. We completed the sale in the second quarter of 2019. Results of operations for these assets are reported in our Lower 48 segment. See Note 14—Fair Value Measurement for additional information. In the second quarter of 2017, we completed the sale of our 50 percent nonoperated interest in the Foster Creek Christina Lake (FCCL) Partnership, as well as the majority of our western Canada gas assets to Cenovus Energy. Consideration for the transaction included a five-year uncapped contingent payment. The contingent payment, calculated on a quarterly basis, is $6 million CAD for every $1 CAD by which the WCS quarterly average crude price exceeds $52 CAD per barrel. Contingent payments received during the five-year period are recorded as “Gain on dispositions” on our consolidated income statement and reflected in our Canada segment. We recorded gains on dispositions for these contingent payments of $ 95 million and $ 104 million in the nine-month periods of 2018 and 2019, respectively. Planned Disposition In October 2019, we announced an agreement to sell the subsidiaries that hold our Australia-West assets and operations to Santos for $ 1.39 billion, plus customary adjustments, with an effective date of January 1, 2019. In addition, we will receive a payment of $ 75 million upon final investment decision of the Barossa development project. These subsidiaries hold our 37.5 percent interest in the Barossa Project and Caldita Field, our 56.9 percent interest in the Darwin LNG Facility and Bayu-Undan Field, our 40 percent interest in the Greater Poseidon Fields, and our 50 percent interest in the Athena Field. At September 30, 2019, the net carrying value was approximately $ 0.6 billion, consisting primarily of $ 1.2 billion of PP&E and $ 0.2 billion of cash and working capital, offset by $ 0.6 billion of ARO and $ 0.2 billion of deferred tax liabilities. This transaction met held for sale criteria in October 2019 and is expected to be completed in the first quarter of 2020, subject to regulatory approvals and other specific conditions precedent. Results of operations for the subsidiaries to be sold are reported within our Asia Pacific and Middle East segment.

Our investment on our consolidated balance sheet as of September 30, 2019, is carried at fair value of $ 1.95 billion, reflecting the closing price of Cenovus Energy shares on the NYSE of $ 9.38 per share on the last trading day of the quarter, an increase of $ 116 million from $ 1.84 billion at the end of the second quarter of 2019 and an increase of $ 489 million from $ 1.46 billion at year-end 2018. The increase in fair value represents the net unrealized gain recorded within the “Other income” line of our consolidated income statement in the first nine months of 2019 relating to the shares held at the reporting date. See Note 14—Fair Value Measurement, for additional information. Subject to market conditions, we intend to decrease our investment over time through market transactions, private agreements or otherwise.

Debt [Abstract]
Debt	Note 9—Debt Our revolving credit facility provides a total commitment of $ 6.0 billion and expires in May 2023 500 million, or as support for our commercial paper program. Our commercial paper program consists of the ConocoPhillips Company $ 6.0 billion program, primarily a funding source for short-term working capital needs. Commercial paper maturities are generally limited to 90 days. We had no commercial paper outstanding at September 30, 2019 or December 31, 2018. We had no direct outstanding borrowings or letters of credit under the revolving credit facility at September 30, 2019 or December 31, 2018. Since we had no commercial paper outstanding and had issued no letters of credit, we had access to $ 6.0 billion in borrowing capacity under our revolving credit facility at September 30, 2019. At September 30, 2019, we had $ 283 million of certain variable rate demand bonds (VRDBs) outstanding with maturities ranging through 2035. The VRDBs are redeemable at the option of the bondholders on any business day. If they are ever redeemed, we intend to refinance on a long-term basis, therefore, the VRDBs are included in the “Long-term debt” line on our consolidated balance sheet.

Guarantees

Guarantees	9 Months Ended
	Sep. 30, 2019
Guarantees [Abstract]
Guarantees	Note 11—Guarantees At September 30, 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 and expect future performance to be either immaterial or have only a remote chance of occurrence. APLNG Guarantees At September 30, 2019, we had outstanding multiple guarantees in connection with our 37.5 percent ownership interest in APLNG. The following is a description of the guarantees with values calculated utilizing September 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 11 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 September 30, 2019, the carrying value of this guarantee was approximately $ 14 million. For additional information, see Note 6—Investments, Loans and Long-Term Receivables.  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 potential liability for future payments, or cost of volume delivery, under these guarantees is estimated to be $ 720 million ($ 1.3 billion in the event of intentional or reckless breach), and would become payable if APLNG fails to meet its obligations under these 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 terms of up to 26 years or the life of the venture. Our maximum potential amount of future payments related to these guarantees is approximately $ 130 million and would become payable if APLNG does not perform. Other Guarantees We have other guarantees with maximum future potential payment amounts totaling approximately $ 800 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 portion of a joint venture’s project finance reserve accounts. These guarantees have remaining terms of up to three 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. In conjunction with the disposition of our two U.K. subsidiaries to Chrysaor E&P Limited, we will temporarily continue to support various guarantees and letters of credit which were provided for the benefit of entities that are now affiliates of Chrysaor E&P Limited. Our maximum potential payment exposure under these obligations is approximately $ 148 million. Chrysaor E&P Limited has agreed to fully indemnify ConocoPhillips for any losses suffered by us related to these obligations. Indemnifications Over the years, we have entered into agreements to sell ownership interests in certain corporations, joint ventures and assets that gave rise to qualifying 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 environmental issues, the term is generally indefinite and the maximum amount of future payments is generally unlimited. The carrying amount recorded for these indemnifications at September 30, 2019, was approximately $ 90 million. We amortize the indemnification liability 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 essentially 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 September 30, 2019, were approximately $ 30 million of environmental accruals for known contamination that are included 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	9 Months Ended

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 case 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 related 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 respect 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. Estimated 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 considerations. 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 our 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 federal 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 designated 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 concerned. 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. Where 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 acquisitions 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 estimated. We have not reduced these accruals for possible insurance recoveries. At September 30, 2019, our consolidated balance sheet included a total environmental accrual of $ 163 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 proceedings. 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 continue 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 professional 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 existing 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 advances and penalties for fees related to throughput capacity not utilized. In addition, at September 30, 2019, we had performance obligations secured by letters of credit of $ 221 million (issued as direct bank letters of credit) related to various purchase 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 government’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 Corocoro 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 ConocoPhillips’ 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 approximately $ 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. On August 29, 2019, the ICSID Tribunal issued a decision rectifying the award and reducing it by approximately $ 227 million. The award now stands at $ 8.5 billion plus interest. The government of Venezuela has announced that it intends to seek annulment of the award. In 2014, ConocoPhillips 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 amount 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 settlement is to be paid quarterly over a period of four and a half years. To date, ConocoPhillips has received approximately $ 754 million. Per the settlement, PDVSA recognized the ICC award as a judgment in various jurisdictions, and ConocoPhillips agreed to suspend its legal enforcement actions. The company is taking steps to secure payment of an outstanding amount of approximately $ 12 million from the initial payment obligation. ConocoPhillips has ensured that the settlement and any actions thereof meet all appropriate U.S. regulatory requirements, including those related to 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. On August 2, 2019, the ICC Tribunal awarded ConocoPhillips approximately $ 55 million under the Corocoro contracts. In February 2017, the ICSID Tribunal unanimously 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 Ecuador 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 included an offset for the counterclaims decision, of which Burlington is entitled to a contribution from Perenco Ecuador Limited, its co-venturer and consortium operator, pursuant to a joint and several liability provision in the JOA. In September 2019, a separate ICSID Tribunal issued an award in the Perenco arbitration, ordering Perenco to pay an additional $ 54 million to Ecuador for its environmental counterclaim. Burlington and Perenco will reconcile their shares of the environmental and infrastructure counterclaims according to their JOA participating interests, and we expect Burlington’s share will be immaterial. 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 arbitration 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. While the arbitration remains pending, the parties reached an agreement in principle in October 2019 to amicably resolve this dispute. 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. Lawsuits filed by other cities and counties in California and Washington are currently stayed pending resolution of the appeals brought by the Cities of San Francisco and Oakland to the U.S. Court of Appeals for the Ninth Circuit. Rulings in lawsuits filed in Maryland and Rhode Island, on the issue of whether the matters should proceed in state or federal court, are on appeal to the U.S. Court of Appeals for the Fourth Circuit and First Circuit, respectively. Several 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. All parish lawsuits are stayed pending an appeal to the Fifth Circuit Court of Appeals on the issue of whether they will proceed in federal or state court. ConocoPhillips will vigorously defend against these lawsuits.

Derivative and Financial Instruments [Abstract]
Derivative and Financial Instruments	Note 13—Derivative and Financial Instruments Derivative Instruments We use futures, forwards, swaps and options in various markets to meet our customer needs and capture market opportunities. Our commodity business primarily consists of natural gas, crude oil, bitumen, LNG and NGLs. Our derivative instruments are held at fair value on our consolidated balance sheet. 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. Gains and losses related to contracts that meet and are designated with the NPNS exception are recognized upon settlement. We generally apply this exception to eligible crude contracts.

Our foreign currency exchange derivative activity primarily relates to managing our cash-related foreign currency exchange rate exposures, such as firm commitments for capital programs or local currency tax payments, dividends and cash returns from net investments in foreign affiliates, and investments in equity securities. We do not elect hedge accounting on our foreign currency exchange derivatives.

The collar expired during the second quarter of 2019 and we entered into new foreign currency exchange forward contracts to sell $1.35 billion CAD at $0.748 CAD against the U.S. dollar. 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 in which 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 on 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 “Short-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 forwards, 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 significant 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 national 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 counterparties. 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 amounts 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 Exchange. The aggregate fair value of all derivative instruments with such credit risk-related contingent features that were in a liability position on September 30, 2019 and December 31, 2018, was $ 47 million and $ 62 million, respectively. For these instruments, no collateral was posted as of September 30, 2019 or December 31, 2018.

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 initially 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. Recurring 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 NYSE. 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 derived value uses industry standard methodologies that may consider the historical relationships among various commodities, modeled market prices, time value, volatility factors and other relevant economic measures. The use of these inputs results in management’s best estimate of fair value. Level 3 activity was not material for all periods presented. The following table summarizes the fair value hierarchy for gross financial assets and liabilities (i.e., unadjusted where the right of setoff exists for commodity derivatives accounted for at fair value on a recurring basis): Millions of Dollars September 30, 2019 December 31, 2018 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Assets Investment in Cenovus Energy $ 1,951 - - 1,951 1,462 - - 1,462 Commodity derivatives 153 86 24 263 236 181 33 450 Total assets $ 2,104 86 24 2,214 1,698 181 33 1,912 Liabilities Commodity derivatives $ 169 82 16 267 225 145 30 400 Total liabilities $ 169 82 16 267 225 145 30 400 The following table summarizes those commodity derivative balances subject to the right of setoff as presented on our consolidated balance sheet.

Non-Recurring Fair Value Measurement The following table summarizes the fair value hierarchy by major category and date of remeasurement for assets accounted for at fair value on a non-recurring basis: Millions of Dollars Fair Value Measurements Using Fair Value Level 1 Inputs Level 2 Inputs Before-Tax Loss Equity method investments March 31, 2019 $ 171 171 - 60 May 31, 2019 30 - 30 95 During the first quarter of 2019, the carrying values of our equity method investments in the Golden Pass LNG Terminal and Golden Pass Pipeline were written down to fair value. The fair values were determined by negotiated selling prices. For additional information, see Note 5—Asset Dispositions. During the second quarter of 2019, our equity method investment in MWCC was determined to have a fair value below its carrying value, and the impairment was considered to be other than temporary. For additional information, see Note 3—Variable Interest Entities. 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 to 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 value 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 and 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.

Non-Mineral Leases

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 buildings. 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 contain 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 components 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 each 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 executed 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 during 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. Lease 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 commencement 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 reimbursement 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 proportional 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. In 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 historically recorded 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 investee 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 December 31, 2018, $ 420 million of finance lease assets (net of accumulated DD&A) and $ 688 million of finance lease liabilities were recorded on our consolidated balance sheet associated with these leases. In accordance with 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 reconsideration 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 summarize 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 September 30, 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 September 30, 2019 Right-of-Use Assets Properties, plants and equipment Gross $ 1,069 Accumulated depreciation, depletion and amortization ( 634) Net properties, plants and equipment * $ 435 Other assets ** $ 805 * Includes proportionately consolidated finance lease assets (net of accumulated depreciation, depletion and amortization) of $ 359 million. **As a result of the sale of two ConocoPhillips U.K. subsidiaries, right-of-use assets decreased approximately $ 0.2 billion in the third quarter of 2019.

During the first nine months of 2019, we contributed $ 174 million to our domestic benefit plans and $ 429 million to our international benefit plans, including a $ 324 million contribution made in conjunction with the completion of our sale of two ConocoPhillips U.K. subsidiaries. In 2019, we expect to contribute approximately $ 220 million to our domestic qualified and nonqualified pension and postretirement benefit plans and $ 455 million to our international qualified and nonqualified pension and postretirement benefit plans. During the three-month period ended September 30, 2019, lump-sum benefit payments exceeded the sum of service and interest costs for the fiscal year for the U.S. qualified pension plan and a U.S. nonqualified supplemental retirement plan. As a result, we recognized a proportionate share of prior actuarial losses from other comprehensive income as pension settlement expense of $ 37 million. In conjunction with the recognition of pension settlement expense, the fair market values of pension plan assets were updated and the pension benefit obligations of the U.S. qualified pension plan and the U.S. nonqualified supplemental retirement plan were remeasured as of September 30, 2019. At the measurement date, the net pension liability increased by $ 108 million. This is primarily a result of a decrease in the discount rate from 4.30 percent at December 31, 2018 to 3.10 percent at September 30, 2019 for the U.S. qualified pension plan and from 4.05 percent at December 31, 2018 to 2.80 percent at September 30, 2019 for the U.S. nonqualified supplemental retirement plan, resulting in a corresponding decrease to other comprehensive income. The sale of two ConocoPhillips U.K. subsidiaries completed during the third quarter of 2019 led to a significant reduction of future services of active employees in certain international pension plans, resulting in a curtailment. In conjunction with the recognition of the curtailment, the fair market values of pension plan assets were updated, the pension benefit obligation was remeasured, and the net pension asset decreased by $ 43 million, resulting in a corresponding decrease to other comprehensive income. This is primarily a result of a decrease in the discount rate from 2.90 percent at December 31, 2018 to 1.80 percent at September 30, 2019 offset by a decrease in the pension benefit obligation from curtailment. Severance Accrual The following table summarizes our severance accrual activity for the nine-month period ended September 30, 2019: Millions of Dollars Balance at December 31, 2018 $ 48 Accruals ( 2) Benefit payments ( 22) Foreign currency translation adjustments ( 1) Balance at September 30, 2019 $ 23 Of the remaining balance at September 30, 2019, $ 6 million is classified as short term.

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 Nine Months Ended September 30 September 30 2019 2018 2019 2018 Revenue from Outside the Scope of ASC Topic 606 by Segment Lower 48 $ 1,099 1,534 3,823 4,547 Canada 86 87 427 374 Europe and North Africa 344 276 731 956 Physical contracts meeting the definition of a derivative $ 1,529 1,897 4,981 5,877 Millions of Dollars Three Months Ended Nine Months Ended September 30 September 30 2019 2018 2019 2018 Revenue from Outside the Scope of ASC Topic 606 by Product Crude oil $ 266 267 619 843 Natural gas 1,159 1,522 4,022 4,775 Other 104 108 340 259 Physical contracts meeting the definition of a derivative $ 1,529 1,897 4,981 5,877 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 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. Receivables and Contract Liabilities Receivables from Contracts with Customers At September 30, 2019, the “Accounts and notes receivable” line on our consolidated balance sheet, includes trade receivables of $ 2,566 million compared with $ 2,889 million at December 31, 2018, 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 little 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 NPNS has been elected. Contract Liabilities from Contracts with Customers We have entered into contractual arrangements where we license our proprietary technology to customers related to the optimization process for operating LNG plants. The contracts typically provide for negotiated payments to be made at 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 installments over the construction period. Millions of Dollars Contract Liabilities At December 31, 2018 $ 206 Contractual payments received 73 Revenue recognized ( 199) At September 30, 2019 $ 80 Amounts Recognized in the Consolidated Balance Sheet at September 30, 2019 Noncurrent liabilities $ 80 $ 80 We expect to recognize the contract liabilities as of September 30, 2019, as revenue between 2021 and 2022.

Segment Disclosures and Related Information	Note 21—Segment Disclosures and Related Information We explore for, produce, transport and market crude oil, bitumen, natural gas, LNG and NGLs on a worldwide basis. We manage our operations through six operating segments, which are primarily defined by geographic region: Alaska, Lower 48, Canada, Europe and North Africa, Asia Pacific and Middle East, and Other International. Corporate and Other represents income and costs not directly associated with an operating segment, such as most interest expense, corporate overhead and certain technology activities, including licensing revenues.

Income Taxes [Abstract]
Income Taxes	Note 22—Income Taxes Our effective tax rates for the three- and nine-month periods ended September 30, 2019, were 12 percent and 21 percent, respectively, compared with 36 percent and 39 percent for the same periods of 2018. T he effective tax rate for the three- and nine -month periods ended September 30, 2019 is lower than the effective tax rate for the same periods of 2018 primarily due to the recognition of a U.S. capital loss benefit related to the disposition of two of our U.K. subsidiaries, the recognition of tax incentives in Malaysia, a reduction in our valuation allowance for 2019, and changes in our mix of income between higher and lower tax jurisdictions. During the three- and nine-month periods ended September 30, 2019 , we recognized a U.S. tax benefit of $ 28 million and $ 262 million, respectively, related to the recognition of a U.S. capital loss benefit on our U.K. entity disposition. During the third quarter of 2019, we received final partner approval in the Malaysia Block G to claim certain deepwater tax credits. As a result, we recorded an income tax benefit of $ 164 million. During the three- and nine-month periods ended September 30, 2019, our valuation allowance decreased by $ 32 million and $ 224 million, respectively, compared to increases of $ 16 million and $ 61 million for the same periods of 2018. The change to our valuation allowance between periods relates primarily to the decrease in the deferred tax asset related to the increase in the fair value measurement of our Cenovus Energy common shares as well as recognition and realization of deferred tax assets due to the disposition of the Greater Sunrise Fields . For additional information on asset dispositions, see Note 5—Asset Dispositions.

Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Note 23—New Accounting Standards In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments” (ASU No. 2016-13), which sets forth the current expected credit loss model, a new forward-looking impairment model for certain financial instruments based on expected losses rather than incurred losses. The ASU is effective for interim and annual periods beginning after December 15, 2019. Entities are required to adopt ASU No. 2016-13 using a modified retrospective approach, subject to certain limited exceptions. The impact of adopting this ASU is not expected to be material to our financial statements.

Significant accounting policies (Policies)	9 Months Ended
	Sep. 30, 2019
Policy Text Block [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]	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 Improvements,” 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 modified 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 comparative 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 historical 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 or existing lease arrangements with terms of 12 months or less. The primary impact of applying ASC Topic 842 is the initial recognition of $ 998 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 reclassification 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.
Revenue Recognition, Policy [Policy Text Block]	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.
Long-Duration Contracts Revenue Recognition, Policy [Policy Text Block]	We have entered into contractual arrangements where we license our proprietary technology to customers related to the optimization process for operating LNG plants. The contracts typically provide for negotiated payments to be made at 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 installments over the construction period.
Lessee, Leases [Policy Text Block]	We adopted ASC Topic 842 using the modified 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 comparative 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 historical 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 or existing lease arrangements with terms of 12 months or less.
