Basis of Presentation	'
	Note 1—Basis of Presentation
	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 2012 Annual Report on Form 10-K.
	As a result of our separation of Phillips 66 on April 30, 2012, the results of operations for our former refining, marketing and transportation businesses; most of our former Midstream segment; our former Chemicals segment; and our power generation and certain technology operations included in our former Emerging Businesses segment (collectively, our “Downstream business”), have been classified as discontinued operations for all periods presented. In addition, the results of operations for our interest in the North Caspian Sea Production Sharing Agreement (Kashagan) and our Algerian and Nigerian businesses have been classified as discontinued operations for all periods presented. See Note 3—Discontinued Operations, for additional information. Unless indicated otherwise, the information in the Notes to the Consolidated Financial Statements relates to our continuing operations.

	Note 2—Change in Accounting Principles
	Effective January 1, 2013, we early adopted, on a prospective basis, Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2013-05, “Parent's Accounting for the Cumulative Translation Adjustment (CTA) upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.”  This ASU clarifies that the CTA should not be released into net income unless a parent sells a part of its investment within a foreign entity which represents the complete or substantially complete liquidation of the reporting parent's investment in the broader foreign entity. The ASU also requires the release of all the related CTA into net income upon gaining control in a step acquisition of an equity method investment that is considered to be a standalone foreign entity, and a pro rata release of the related CTA into net income upon a partial sale of an interest in an equity method investment that is considered to be a standalone foreign entity. There was no impact to our consolidated financial statements from the early adoption of this standard.

Separation of Downstream Business	'
	Note 3—Discontinued Operations
	Separation of Downstream Business
	On April 30, 2012, the separation of our Downstream business was completed, creating two independent energy companies: ConocoPhillips and Phillips 66. In connection with the separation, Phillips 66 distributed approximately $7.8 billion to us in a special cash distribution. The principal funds from the special cash distribution were designated solely to pay dividends, repurchase common stock, repay debt, or a combination of the foregoing, within twelve months following the distribution. The cash was included in the “Restricted cash” line on our consolidated balance sheet. No balance remained from the cash distribution as of September 30, 2013. We also entered into several agreements with Phillips 66 in order to effect the separation and govern our relationship with Phillips 66.
	Sales and other operating revenues and income from discontinued operations related to Phillips 66 for the
	three- and nine-month periods ended September 30, 2012, were as follows:
			Millions of Dollars
			2012
			Three Months Ended			Nine Months Ended
			30-Sep			30-Sep
	Sales and other operating revenues from discontinued
		operations	$		2		62,109
	Income from discontinued operations before-tax		$		2		1,792
	Income tax expense				-		542
	Income from discontinued operations		$		2		1,250
	Income from discontinued operations after-tax includes transaction, information systems and other costs incurred to effect the separation of $70 million for the nine-month period ended September 30, 2012. No separation costs were incurred during the first nine months of 2013.
	Prior to the separation, commodity sales to and purchases from Phillips 66 were $4,973 million and $166 million, respectively, for the nine-month period ended September 30, 2012. Prior to May 1, 2012, commodity sales and related costs were eliminated in consolidation between ConocoPhillips and Phillips 66. Beginning May 1, 2012, these revenues and costs represent third-party transactions with Phillips 66.
	Other Discontinued Operations
	As part of our ongoing asset disposition program, we agreed to sell our interest in Kashagan and our Algerian and Nigerian businesses (collectively, the “Disposition Group”). The Disposition Group was previously part of the Other International operating segment.
	On November 26, 2012, we notified government authorities in Kazakhstan and co-venturers of our intent to sell the Company's 8.4 percent interest in Kashagan to ONGC Videsh Limited (OVL). On July 2, 2013, we received notification from the government of Kazakhstan indicating it is exercising its right to pre-empt the proposed sale to OVL and designating KazMunayGas (KMG) as the entity to acquire the interest. On October 31, 2013, we completed the transaction with KMG for total proceeds of $5.4 billion. We recorded pre-tax impairments of $606 million and $43 million in the fourth quarter of 2012 and the first quarter of 2013, respectively. At September 30, 2013, the carrying value of the net assets related to our interest in Kashagan was $5.3 billion, net of impairments.
	On December 18, 2012, we entered into an agreement with Pertamina to sell our wholly owned subsidiary, ConocoPhillips Algeria Ltd., for a total of $1.75 billion plus customary adjustments. The transaction is targeted to close by the end of 2013. We received a deposit of $175 million in December 2012. The deposit is refundable in the event our co-venturer exercises its preemptive rights, which have been waived, or government approval is not received. At September 30, 2013, the net carrying value of our Algerian assets was $714 million.
	On December 20, 2012, we entered into agreements with affiliates of Oando PLC to sell our Nigerian business unit. This included its upstream affiliates and Phillips (Brass) Limited, which owns a 17 percent interest in the Brass LNG Project. Brass LNG plans to construct an LNG facility in the Niger Delta. In September 2013, we agreed to extend the outside date, or the date the sales agreements may terminate, for our Nigerian upstream affiliates to November 30, 2013, in order to provide additional time for Oando to obtain financing. This sale is expected to generate proceeds of $1.65 billion plus customary adjustments. We received a deposit of $435 million in December 2012 and may retain the deposit if closing does not occur due to default by the buyer or failure to obtain all consents required under Nigerian petroleum laws. In September 2013, we also agreed to extend the date for closing the sale of our interest in Brass LNG to the first quarter of 2014, subject to certain conditions. The sale of Brass LNG would generate proceeds of $105 million plus customary adjustments. At September 30, 2013, the net carrying value of our Nigerian assets was $371 million.
	At September 30, 2013, each component of the Disposition Group met the criteria to be classified as held for sale. Accordingly, we classified $11 million of loans and advances to related parties in the “Accounts and notes receivable—related parties” line and $7,421 million of noncurrent assets in the “Prepaid expenses and other current assets” line of our consolidated balance sheet. In addition, we classified $905 million of noncurrent liabilities in the “Accrued income and other taxes” line and $136 million of asset retirement obligations in the “Other accruals” line of our consolidated balance sheet. The carrying amounts of the major classes of assets and liabilities associated with the Disposition Group were as follows:

Variable Interest Entities VIEs [Abstract]	'
Variable Interest Entities (VIEs)	'
	Note 4—Variable Interest Entities (VIEs)
	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:
	Freeport LNG Development, L.P. (Freeport LNG)
	We have an agreement with Freeport LNG to participate in an LNG receiving terminal in Quintana, Texas. We have no ownership in Freeport LNG; however, we own a 50 percent interest in Freeport LNG GP, Inc. (Freeport GP), which serves as the general partner managing the venture. We entered into a credit agreement with Freeport LNG, whereby we agreed to provide loan financing for the construction of the terminal. We also entered into a long-term agreement with Freeport LNG to use 0.9 billion cubic feet per day of regasification capacity, which expires in 2033. The terminal became operational in June 2008, and we began making payments under the terminal use agreement. At September 30, 2013, the prepaid balance of the terminal use agreement was $269 million, which is primarily reflected in the “Other assets” line on our consolidated balance sheet. Freeport LNG began making loan repayments in September 2008, and the loan balance outstanding was $522 million at September 30, 2013, and $565 million at December 31, 2012.
	In July 2013, we reached an agreement with Freeport LNG to terminate our long-term agreement at the Freeport LNG Terminal, subject to Freeport LNG obtaining regulatory approval and project financing for an LNG liquefaction and export facility in Texas, in which we are not a participant.  Upon satisfaction of these conditions, currently expected to occur by the end of the first quarter of 2014, we will pay Freeport LNG a termination fee of approximately $600 million.  Freeport LNG will repay the outstanding ConocoPhillips loan used by Freeport to partially fund the original construction of the terminal.  When the agreement becomes effective, we expect to recognize an after-tax charge to earnings of approximately $540 million.  At that time, our terminal regasification capacity will be reduced from 0.9 billion cubic feet per day to 0.4 billion cubic feet per day, until July 1, 2016, at which time it will be reduced to zero.
	Freeport LNG is a VIE because Freeport GP holds no equity in Freeport LNG, and the limited partners of Freeport LNG do not have any substantive decision making ability. Since we do not have the unilateral power to direct the key activities which most significantly impact its economic performance, we are not the primary beneficiary of Freeport LNG. These key activities primarily involve or relate to operating and maintaining the terminal. We also performed an analysis of the expected losses and determined we are not the primary beneficiary. This expected loss analysis took into account that the credit support arrangement requires Freeport LNG to maintain sufficient commercial insurance to mitigate any loan losses. The loan to Freeport LNG is accounted for as a financial asset, and our investment in Freeport GP is accounted for as an equity investment.
	Australia Pacific LNG (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 coalbed methane, 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, 2013, 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 7—Investments, Loans and Long-Term Receivables, and Note 13—Guarantees, for additional information.

	Our interest in Kashagan and the Algerian and Nigerian business units were considered held for sale at September 30, 2013. These assets are classified as discontinued operations. See Note 3—Discontinued Operations, for additional information.
	In March 2013, we sold the majority of our properties in the Cedar Creek Anticline for $989 million and recognized a before-tax loss on disposition of $49 million, which was included in the “Gain on dispositions” line on our consolidated income statement for the nine-month period ended September 30, 2013. At the time of the disposition, the carrying value of our interest, which was included in the Lower 48 and Latin America segment, was $1,038 million, which included $1,066 million of properties, plants and equipment (PP&E) and $28 million of asset retirement obligations.
	In June 2013, we sold a portion of our working interests in the Browse and Canning basins for $402 million. Because we retained a working interest in the unproved properties, proceeds were treated as a reduction of the carrying value of PP&E with no gain or loss on disposition recognized. Prior to the partial disposition, the carrying value of the PP&E associated with our interests, included in our Asia Pacific and Middle East segment, was $486 million.
	In August 2013, we sold our interest in the Clyden undeveloped oil sands leasehold for $724 million and recognized a before-tax gain on disposition of $614 million, which was included in the “Gain on dispositions” line on our consolidated income statement for the three- and nine-month periods ended September 30, 2013. At the time of the disposition, the carrying value of our interest in Clyden, which was included in the Canada segment, was $110 million and was classified as PP&E.
	In August 2013, we also sold our 39 percent interest in Phoenix Park Gas Processors Limited for $593 million and recognized a before-tax gain on disposition of $417 million, which was included in the “Gain on dispositions” line on our consolidated income statement for the three- and nine-month periods ended September 30, 2013.  At the time of the disposition, the carrying value of our equity investment in Phoenix Park, which was included in our Lower 48 and Latin America segment, was $176 million.

	APLNG
	In the fourth quarter of 2012, APLNG satisfied all conditions precedent to drawdown from the $8.5 billion project finance facility. The facility consists 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 billion, and a syndicate of Australian and international commercial banks for approximately $2.9 billion. In connection with the execution of the project financing, we provided a completion guarantee for our pro-rata share of the project finance facility until the project achieves financial completion. See Note 13—Guarantees, for additional information.
	APLNG is considered a VIE, as it has entered into certain contractual arrangements that provide it with additional forms of subordinated financial support. See Note 4—Variable Interest Entities (VIEs), for additional information.
	At September 30, 2013, the book value of our equity method investment in APLNG was $10,526 million, which included $1,601 million of cumulative translation effects due to strengthening of the Australian dollar relative to the U.S. dollar over time, and is included in the “Investments and long-term receivables” line on our consolidated balance sheet.
	Loans and Long-Term Receivables
	As part of our normal ongoing business operations and consistent with industry practice, we enter into numerous agreements with other parties to pursue business opportunities. Included in such activity are loans made to certain affiliated and non-affiliated companies. Significant loans to affiliated companies at September 30, 2013, included the following:
	$522 million in loan financing to Freeport LNG. See Note 4—Variable Interest Entities (VIEs), for additional information.
	$1,005 million in project financing to Qatar Liquefied Gas Company Limited (3) (QG3).
	The long-term portion of these loans is included in the “Loans and advances—related parties” line on our consolidated balance sheet, while the short-term portion is in “Accounts and notes receivable—related parties.”

	The nine-month periods of 2013 and 2012 included impairments in our Europe segment of $28 million and $79 million, respectively, primarily due to increases in the asset retirement obligation for the U.K. Don Field, which has ceased production. Additionally, the nine-month period of 2012 included a $213 million property impairment in our Canada segment for the carrying value of capitalized project development costs associated with our Mackenzie Gas Project. Advancement of the project was suspended indefinitely in the first quarter of 2012 due to a continued decline in market conditions and the lack of acceptable commercial terms. We also recorded a $481 million impairment for the undeveloped leasehold costs associated with the project, which was included in the “Exploration expenses” line on our consolidated income statement.

Debt	'
	Note 10—Debt
	We have two commercial paper programs supported by our $7.5 billion revolving credit facility: the ConocoPhillips $6.35 billion program, primarily a funding source for short-term working capital needs, and the ConocoPhillips Qatar Funding Ltd. $1.15 billion program, which is used to fund commitments relating to QG3. Commercial paper maturities are generally limited to 90 days.
	At September 30, 2013, and December 31, 2012, we had no direct outstanding borrowings or letters of credit issued under our revolving credit facilities. In addition, under the ConocoPhillips Qatar Funding Ltd. commercial paper program, there was $961 million of commercial paper outstanding at September 30, 2013, compared with $1,055 million at December 31, 2012. Since we had $961 million of commercial paper outstanding and had issued no letters of credit, we had access to $6.5 billion in borrowing capacity under our revolving credit facilities at September 30, 2013.
	At September 30, 2013, we classified $865 million of short-term debt as long-term debt, based on our ability and intent to refinance the obligation on a long-term basis under our revolving credit facilities.
	During the first nine months of 2013, we repaid the following debt instruments at maturity:
	The $100 million 7.625% Debentures due 2013.
	The $750 million 5.50% Notes due 2013.
	During the second quarter of 2013, a lease of a semi-submersible floating production system (FPS) commenced for the Gumusut development, located in Malaysia, in which we are a co-venturer. The FPS lease provides for an initial noncancelable term of 15 years, a subsequent 5-year cancelable term with no required lease payments, and an additional 5-year term with terms and conditions to be agreed at a later date. The lease has no ongoing purchase options or escalation clauses. Certain contingent rental payments may be incurred if actual commissioning costs exceed provisioned amounts. The lease does not impose any significant restrictions concerning dividends, debt or further leasing activities.
	A capital lease asset and a capital lease obligation of $906 million were recognized for our proportionate interest in the FPS. The value of the capital lease asset and associated obligation are based on the present value of the future minimum lease payments using our pre-tax incremental borrowing rate of 3.58 percent for debt with similar terms. Following the startup of the FPS, the capital lease asset will be depreciated over a period consistent with the estimated proved reserves of Gumusut using the unit-of-production method with the associated depreciation included in the “Depreciation, depletion and amortization” line on our consolidated income statement. Future minimum lease payments under the capital lease are $46 million for the remainder of 2013, $78 million per year for 2014 through 2017, and $814 million for all years thereafter.

Guarantees [Abstract]	'
Guarantees	'
	Note 13—Guarantees
	At September 30, 2013, 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 either because the guarantees were issued prior to December 31, 2002, or 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, 2013, we have 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 2013 exchange rates:
	We have guaranteed APLNG's performance with regard to a construction contract executed in connection with APLNG's issuance of the Train 1 and Train 2 Notices to Proceed. We estimate the remaining term of this guarantee is four years. Our maximum potential amount of future payments related to this guarantee is approximately $150 million and would become payable if APLNG cancels the applicable construction contract and does not perform with respect to the amounts owed to the contractor.
	We have issued a construction completion guarantee related to the third-party project financing secured by APLNG. Our maximum potential amount of future payments under the guarantee is estimated to be $3.2 billion, which could be payable if the full debt financing capacity is utilized and completion of the project is not achieved. Our guarantee of the project financing will be released upon meeting certain completion tests with milestones, which we estimate would occur beginning in 2016. Our maximum exposure at September 30, 2013, is $2.5 billion based upon our pro-rata share of the facility used at that date. At September 30, 2013, the carrying value of this guarantee is approximately $114 million.
	In conjunction with our original purchase of an ownership interest in APLNG from Origin Energy in October 2008, we agreed to guarantee an existing obligation of APLNG to deliver natural gas under several sales agreements with remaining terms of 3 to 18 years. Our maximum potential amount of future payments, or cost of volume delivery, under these guarantees is estimated to be $1.0 billion ($2.1 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 32 years or the life of the venture. Our maximum potential amount of future payments related to these guarantees is approximately $200 million and would become payable if APLNG does not perform.
	Other Guarantees
	We have other guarantees with maximum future potential payment amounts totaling approximately $270 million, which consist primarily of guarantees of the residual value of leased corporate aircraft, guarantees to fund the short-term cash liquidity deficit of two joint ventures, a guarantee for our portion of a joint venture's debt obligations and a guarantee of minimum charter revenue for an LNG vessel. These guarantees have remaining terms of up to 11 years or the life of the venture 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 non-performance of contractual terms by guaranteed parties.
	Indemnifications
	Over the years, we have entered into various lease agreements or agreements to sell ownership interests in certain corporations, joint ventures and assets that gave rise to qualifying indemnifications. Agreements associated with these leases and sales include indemnifications for taxes, environmental liabilities, permits and licenses, employee claims, real estate indemnity against tenant defaults, 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, 2013, was approximately $60 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, 2013, were approximately $50 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 14—Contingencies and Commitments.
	In connection with the separation of the Downstream business, the Company entered into an Indemnification and Release Agreement with Phillips 66. This agreement provided for cross-indemnities between Phillips 66 and ConocoPhillips and established procedures for handling claims subject to indemnification and related matters. We evaluated the impact of the indemnifications given and the Phillips 66 indemnifications received as of the separation date and concluded those fair values were immaterial.

Contingencies and Commitments [Abstract]	'
Contingencies and Commitments	'
	Note 14—Contingencies and Commitments
	A number of lawsuits involving a variety of claims arising in the ordinary course of business have been made 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. Environmental Protection Agency (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 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 in respect of sites 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. At September 30, 2013, our balance sheet included a total environmental accrual of $355 million, compared with $364 million at December 31, 2012, for remediation activities in the U.S. and Canada. We expect to incur a substantial amount of these expenditures within the next 30 years. We have not reduced these accruals for possible insurance recoveries. In the future, we may be involved in additional environmental assessments, cleanups and proceedings.
	Legal Proceedings
	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, are 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, 2013, we had performance obligations secured by letters of credit of $809 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, we announced we had been unable to reach agreement with respect to our migration to an 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, we filed a request for international arbitration on November 2, 2007, with the World Bank's International Centre for Settlement of Investment Disputes (ICSID). An arbitration hearing was held before an ICSID tribunal during the summer of 2010. On September 3, 2013, an ICSID arbitration tribunal held that Venezuela unlawfully expropriated ConocoPhillips' significant oil investments in June 2007. An additional arbitration phase is now proceeding to determine the amount of damages owed to ConocoPhillips for Venezuela's actions.
	In 2008, Burlington Resources, Inc., a wholly owned subsidiary of ConocoPhillips, initiated arbitration before ICSID against The Republic of Ecuador, as a result of the newly enacted Windfall Profits Tax Law and government-mandated renegotiation of our production sharing contracts. Despite a restraining order issued by the ICSID tribunal, Ecuador confiscated the crude oil production of Burlington and its co-venturer and sold the seized crude oil.  In 2009, Ecuador took over operations in Blocks 7 and 21, fully expropriating our assets. In June 2010, the ICSID tribunal concluded it has jurisdiction to hear the expropriation claim. On April 24, 2012, Ecuador filed a supplemental counterclaim asserting environmental damages, which we believe are not material. The ICSID tribunal issued a decision on liability on December 14, 2012, in favor of Burlington, finding that Ecuador's seizure of Blocks 7 and 21 was an unlawful expropriation in violation of the Ecuador-U.S. Bilateral Investment Treaty. An additional arbitration phase is now proceeding to determine the damages owed to ConocoPhillips for Ecuador's actions.
	ConocoPhillips served a Notice of Arbitration on the Timor-Leste Minister of Finance in October 2012 for outstanding disputes related to a series of tax assessments. Between December 2010 and September 2013, ConocoPhillips paid, under protest, tax assessments totaling approximately $232 million, which are primarily recorded in the “Investments and long-term receivables” line on our consolidated balance sheet. The arbitration will be conducted in Singapore under the United Nations Commission on International Trade Laws (UNCITRAL) arbitration rules, pursuant to the terms of the Tax Stability Agreement with the Timor-Leste government. The arbitration process is currently underway. Future impacts on our business are not known at this time.

	We have certain financial instruments on our consolidated balance sheet related to interest bearing time deposits and commercial paper. The following held-to-maturity financial instruments are included in “Cash and cash equivalents” on our consolidated balance sheet:
		Millions of Dollars
		30-Sep			31-Dec
		2013			2012
Cash	$	759		829
Time deposits		3,124		2,789
	$	3,883		3,618
In conjunction with the separation of our Downstream business, we received a special cash distribution from Phillips 66. See Note 3—Discontinued Operations, for additional information. The balance of the special cash distribution was zero at September 30, 2013, and $748 million at December 31, 2012, and was included in “Restricted cash” on our consolidated balance sheet. At December 31, 2012, the funds in the restricted cash account were invested in money market funds with maturities within 90 days from December 31, 2012.
Credit Risk
Financial instruments potentially exposed to concentrations of credit risk consist primarily of cash equivalents, over-the-counter (OTC) derivative contracts and trade receivables. Our cash equivalents are placed in high-quality commercial paper, 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 and swaps, 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 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 certain transactions administered through the New York Mercantile Exchange or the IntercontinentalExchange.
The aggregate fair value of all derivative instruments with such credit-risk-related contingent features that were in a liability position on September 30, 2013, and December 31, 2012, was $83 million and $130 million, respectively. For these instruments, no collateral was posted as of September 30, 2013, or December 31, 2012. If our credit rating had been lowered one level from its “A” rating (per Standard and Poor's) on September 30, 2013, we would be required to post no additional collateral to our counterparties. If we had been downgraded below investment grade, we would be required to post $83 million of additional collateral, either with cash or letters of credit.

Fair Value Measurement [Abstract]	'
Fair Value Measurement	'
	Note 16—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 which 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 that are 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 in or out of Level 1.
	Recurring Fair Value Measurement
	Financial assets and liabilities reported at fair value on a recurring basis primarily include commodity derivatives and certain investments to support nonqualified deferred compensation plans. The deferred compensation investments are measured at fair value using unadjusted prices available from national securities exchanges; therefore, these assets are categorized as Level 1 in the fair value hierarchy. 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 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 that are long term in nature and 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.
	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):

	At September 30, 2013, and December 31, 2012, we did not present any amounts gross on our consolidated
	balance sheet where we had the right of setoff.
	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 restricted cash: The carrying amount reported on the balance sheet approximates fair value.
	Accounts and notes receivable (including long-term and related parties): The carrying amount reported on the 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.
	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 7—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 the balance sheet approximates fair value. The valuation technique and methods used to estimate the fair value of the current portion of the joint venture acquisition obligation is consistent with the methodology below.
	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.
	Joint venture acquisition obligation—related party: Fair value is estimated based on the net present value of the future cash flows as a Level 2 fair value. At September 30, 2013, and December 31, 2012, effective yield rates were 0.74 percent and 0.7 percent, respectively, based on yields of U.S. Treasury securities of similar average duration adjusted for our average credit risk spread and the amortizing nature of the obligation principal. See Note 11—Joint Venture Acquisition Obligation, for additional information.

	In connection with the separation of the Downstream business on April 30, 2012, ConocoPhillips entered into an Employee Matters Agreement with Phillips 66 which provides that employees of Phillips 66 will no longer participate in benefit plans sponsored or maintained by ConocoPhillips upon separation.  As such, changes in net periodic benefit cost included in the table above primarily relate to the employees of Phillips 66 no longer participating in the ConocoPhillips benefit plans for the nine-month period ended September 30, 2013.
	During the first nine months of 2013, we contributed $231 million to our domestic benefit plans and $155 million to our international benefit plans.
	During the three months ended September 30, 2013, we concluded that lump-sum benefit payments will exceed the sum of service and interest costs for the plan year for the U.S. qualified pension plan. As a result, we recognized a proportionate share of prior actuarial losses, or pension settlement expense, of $50 million. In conjunction with the recognition of pension settlement expense, the assets and pension benefit obligation of the qualified pension plan were remeasured. At the measurement date, the net pension liability decreased $301 million to $725 million, resulting in a corresponding increase to other comprehensive income.
	During the three months ended September 30, 2012, we concluded that lump-sum benefit payments would exceed the sum of service and interest costs for the plan year for the U.S. qualified pension plan and U.S. non-qualified supplemental retirement plan. As a result, we recognized a proportionate share of prior actuarial losses, or pension settlement expense, of $137 million. In conjunction with the recognition of pension settlement expense, the assets and pension benefit obligation of the qualified pension plan were remeasured. At the measurement date, the net pension liability increased $432 million to $1,283 million, resulting in a corresponding decrease to other comprehensive income.

We manage our operations through six operating segments, which are defined by geographic region: Alaska, Lower 48 and Latin America, Canada, Europe, Asia Pacific and Middle East, and Other International.
	On April 30, 2012, our Downstream business was separated into a stand-alone, publicly traded corporation, Phillips 66. In 2012, we also agreed to sell our Nigerian and Algerian businesses and our interest in Kashagan. Accordingly, results for these operations have been reported as discontinued operations in all periods presented. Commodity sales to Phillips 66, which were previously eliminated in consolidation prior to the separation, are now reported as third-party sales. For additional information, see Note 3—Discontinued Operations.

	Note 22—Income Taxes
	Our effective tax rates from continuing operations were 45 percent for both the third quarter and first nine months of 2013, compared with 52 percent for the corresponding periods of 2012. The lower rates were primarily due to a smaller proportion of income in higher tax jurisdictions in 2013, as well as tax expense recognized in the third quarter of 2012 associated with a change in U.K. tax legislation. Additionally, the tax rate for the first nine months of 2013 reflected a favorable tax resolution associated with the sale of certain western Canada properties, which occurred in a prior year.
	During the first nine months of 2013, unrecognized tax benefits decreased $220 million to $652 million at September 30, 2013, mainly due to the favorable tax resolution noted above. Included in this balance is $419 million which, if recognized, would impact our effective tax rate.
	For both the third quarter and the first nine months of 2013, the effective tax rate in excess of the domestic federal statutory rate of 35 percent was primarily due to foreign taxes.

	We have various cross guarantees among ConocoPhillips, ConocoPhillips Company, ConocoPhillips Australia Funding Company, ConocoPhillips Canada Funding Company I, and ConocoPhillips Canada Funding Company II, with respect to publicly held debt securities. ConocoPhillips Company is 100 percent owned by ConocoPhillips. ConocoPhillips Australia Funding Company, ConocoPhillips Canada Funding Company I and ConocoPhillips Canada Funding Company II are indirect, 100 percent owned subsidiaries of ConocoPhillips Company. ConocoPhillips and ConocoPhillips Company have fully and unconditionally guaranteed the payment obligations of ConocoPhillips Australia Funding Company, ConocoPhillips Canada Funding Company I, and ConocoPhillips Canada Funding Company II, with respect to their publicly held debt securities. Similarly, ConocoPhillips has fully and unconditionally guaranteed the payment obligations of ConocoPhillips Company with respect to its publicly held debt securities. In addition, ConocoPhillips Company has fully and unconditionally guaranteed the payment obligations of ConocoPhillips with respect to its publicly held debt securities. All guarantees are joint and several. The following condensed consolidating financial information presents the results of operations, financial position and cash flows for:
	ConocoPhillips, ConocoPhillips Company, ConocoPhillips Australia Funding Company, ConocoPhillips Canada Funding Company I, and ConocoPhillips Canada Funding Company II (in each case, reflecting investments in subsidiaries utilizing the equity method of accounting).
	All other nonguarantor subsidiaries of ConocoPhillips.
	The consolidating adjustments necessary to present ConocoPhillips' results on a consolidated basis.
	This condensed consolidating financial information should be read in conjunction with the accompanying consolidated financial statements and notes.
	Subsequent to September 30, 2013, we completed a legal amalgamation of ConocoPhillips Canada Funding Company I, ConocoPhillips Canada Funding Company II and Burlington Resources Finance Company, with the amalgamated company continuing as ConocoPhillips Canada Funding Company I. The amalgamation did not significantly change the nature of the outstanding debt of these entities or the terms of parental guarantees, which remain full and unconditional, as well as joint and several. We do not expect the amalgamation to impact our consolidated financial position, results of operations or cash flows.
