Variable Interest Entity, Not Primary Beneficiary, Disclosures [Abstract]
Variable Interest Entity Disclosure [Text Block]	Note 3—Variable Interest Entities We hold variable interests in VIEs for which there are existing arrangements that provide those entities with additional forms of subordinated financial support. However, as we are not considered the primary beneficiary, these entities have not been consolidated in our financial statements. Marine Well Containment Company, LLC (MWCC) 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. 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 15—Fair Value Measurement. At December 31, 2019, the book value of our equity method investment in MWCC was $ 24 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. Australia Pacific LNG Pty Ltd (APLNG) We hold a 37.5 percent interest in APLNG, our joint venture with Origin Energy and Sinopec. We are not the primary beneficiary because we share, with our joint venture partners, the power to direct the key activities of APLNG that most significantly impacts its economic performance. Therefore, we do not consolidate APLNG and account for this entity as an equity method investment. As of December 31, 2019, we no longer have certain guarantees that provide APLNG with additional subordinated financial support. For additional information see Note 12—Guarantees.
