Miscellaneous Financial Information [Abstract]
Miscellaneous Financial Information	2. Miscellaneous Financial Information During the first quarter of 2020, the balance of supply and demand for petroleum and petrochemical products experienced two significant disruptive effects. On the demand side, the COVID-19 pandemic spread rapidly through most areas of the world resulting in substantial reductions in consumer and business activity and significantly reduced demand for crude oil, natural gas, and petroleum products. This reduction in demand coincided with announcements of increased production in certain key oil producing countries which led to sharp declines in prices for crude oil and other petrochemical products, and considerable volatility in financial markets during the first half of 2020. Crude oil, products and merchandise inventories are carried at the lower of current market value or cost, generally determined under the last-in first-out method (LIFO). The Corporation’s results for the second quarter of 2020 included a before-tax credit of $ 2,624 million, included in “Crude oil and product purchases” on the Statement of Income, as rising commodity prices reduced the charge against the book value of inventories from $ 2,777 million in the first quarter to $ 153 million in the second quarter. This adjustment, together with a similar adjustment for equity companies included in “Income from equity affiliates,” resulted in a $ 1,922 million after-tax credit to earnings (excluding noncontrolling interests) in the second quarter and will be re-evaluated at the end of each quarter in 2020. The earnings impact may be adjusted upward or downward this year based on prevailing market prices at the time of future evaluations. At year-end, any required adjustment is considered permanent and is incorporated into the LIFO carrying value of the inventory. As a result of sharp declines in prices for crude oil and other petrochemical products in the first half of 2020 and a significant decline in its market capitalization at the end of the first quarter, the Corporation recognized after-tax impairment charges of $ 836 million in the first half of 2020. These charges included goodwill impairments of $ 562 million in Upstream, Downstream, and Chemical reporting units and other impairment charges of $ 274 million, mainly in the Upstream segment. Fair value of the goodwill reporting units primarily reflected market-based estimates of historical EBITDA multiples at the end of the first quarter. Other impairment charges, mainly related to the Corporation’s investment in an Upstream equity company, were written down to estimated fair value based on recent third party price outlooks, internal estimates of future volumes and costs, and estimates of discount rates for similar properties. The charges related to goodwill impairment are included in “Depreciation and depletion” on the Statement of Income while the charges related to other impairments are largely included in “Income from equity affiliates.”

Litigation And Other Contingencies [Abstract]
Litigation And Other Contingencies	3. Litigation and Other Contingencies Litigation A variety of claims have been made against ExxonMobil and certain of its consolidated subsidiaries in a number of pending lawsuits. Management has regular litigation reviews, including updates from corporate and outside counsel, to assess the need for accounting recognition or disclosure of these contingencies. The Corporation accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. 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. The Corporation does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and which are significant, the Corporation discloses the nature of the contingency and, where feasible, an estimate of the possible loss. For purposes of our contingency disclosures, “significant” includes material matters, as well as other matters which management believes should be disclosed. ExxonMobil will continue to defend itself vigorously in these matters. Based on a consideration of all relevant facts and circumstances, the Corporation does not believe the ultimate outcome of any currently pending lawsuit against ExxonMobil will have a material adverse effect upon the Corporation's operations, financial condition, or financial statements taken as a whole. Other Contingencies The Corporation and certain of its consolidated subsidiaries were contingently liable at June 30, 2020, for guarantees relating to notes, loans and performance under contracts. Where guarantees for environmental remediation and other similar matters do not include a stated cap, the amounts reflect management’s estimate of the maximum potential exposure. These guarantees are not reasonably likely to have a material effect on the Corporation’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. As of June 30, 2020 Equity Other Company Third Party Obligations (1) Obligations Total (millions of dollars) Guarantees Debt-related 904 113 1,017 Other 692 4,663 5,355 Total 1,596 4,776 6,372 (1) ExxonMobil share Additionally, the Corporation and its affiliates have numerous long-term sales and purchase commitments in their various business activities, all of which are expected to be fulfilled with no adverse consequences material to the Corporation’s operations or financial condition. The operations and earnings of the Corporation and its affiliates throughout the world have been, and may in the future be, affected from time to time in varying degree by political developments and laws and regulations, such as forced divestiture of assets; restrictions on production, imports and exports; price controls; tax increases and retroactive tax claims; expropriation of property; cancellation of contract rights and environmental regulations. Both the likelihood of such occurrences and their overall effect upon the Corporation vary greatly from country to country and are not predictable. In accordance with a Venezuelan nationalization decree issued in February 2007, a subsidiary of the Venezuelan National Oil Company (PdVSA) assumed the operatorship of the Cerro Negro Heavy Oil Project. The decree also required conversion of the Cerro Negro Project into a “mixed enterprise” and an increase in PdVSA’s or one of its affiliate’s ownership interest in the Project. ExxonMobil refused to accede to the terms proffered by the government, and on June 27, 2007, the government expropriated ExxonMobil’s 41.67 percent interest in the Cerro Negro Project. ExxonMobil collected awards of $ 908 million in an arbitration against PdVSA under the rules of the International Chamber of Commerce in respect of an indemnity related to the Cerro Negro Project and $ 260 million in an arbitration for compensation due for the La Ceiba Project and for export curtailments at the Cerro Negro Project under rules of International Centre for Settlement of Investment Disputes (ICSID). An ICSID arbitration award relating to the Cerro Negro Project’s expropriation ($ 1.4 billion) was annulled based on a determination that a prior Tribunal failed to adequately explain why the cap on damages in the indemnity owed by PdVSA did not affect or limit the amount owed for the expropriation of the Cerro Negro Project. ExxonMobil filed a new claim seeking to restore the original award of damages for the Cerro Negro Project with ICSID on September 26, 2018. The net impact of this matter on the Corporation’s consolidated financial results cannot be reasonably estimated. Regardless, the Corporation does not expect the resolution to have a material effect upon the Corporation’s operations or financial condition. An affiliate of ExxonMobil is one of the Contractors under a Production Sharing Contract (PSC) with the Nigerian National Petroleum Corporation (NNPC) covering the Erha block located in the offshore waters of Nigeria. ExxonMobil's affiliate is the operator of the block and owns a 56.25 percent interest under the PSC. The Contractors are in dispute with NNPC regarding NNPC's lifting of crude oil in excess of its entitlement under the terms of the PSC. In accordance with the terms of the PSC, the Contractors initiated arbitration in Abuja, Nigeria, under the Nigerian Arbitration and Conciliation Act. On October 24, 2011, a three-member arbitral Tribunal issued an award upholding the Contractors' position in all material respects and awarding damages to the Contractors jointly in an amount of approximately $ 1.8 billion plus $ 234 million in accrued interest. The Contractors petitioned a Nigerian federal court for enforcement of the award, and NNPC petitioned the same court to have the award set aside. On May 22, 2012, the court set aside the award. The Contractors appealed that judgment to the Court of Appeal, Abuja Judicial Division. On July 22, 2016, the Court of Appeal upheld the decision of the lower court setting aside the award. On October 21, 2016, the Contractors appealed the decision to the Supreme Court of Nigeria. In June 2013, the Contractors filed a lawsuit against NNPC in the Nigerian federal high court in order to preserve their ability to seek enforcement of the PSC in the courts if necessary. Following dismissal by this court, the Contractors appealed to the Nigerian Court of Appeal in June 2016. In October 2014, the Contractors filed suit in the United States District Court for the Southern District of New York (SDNY) to enforce, if necessary, the arbitration award against NNPC assets residing within that jurisdiction. NNPC moved to dismiss the lawsuit. On September 4, 2019, the SDNY dismissed the Contractors’ petition to recognize and enforce the Erha arbitration award. The Contractors filed a notice of appeal in the Second Circuit on October 2, 2019. At this time, the net impact of this matter on the Corporation's consolidated financial results cannot be reasonably estimated. However, regardless of the outcome of enforcement proceedings, the Corporation does not expect the proceedings to have a material effect upon the Corporation's operations or financial condition.

The fair value is calculated by discounting the remaining obligations by a rate consistent with the credit quality and industry of the company. At June 30, 2020, the Corporation had $ 496 million of collateral under master netting arrangements not offset against the derivatives on the Consolidated Balance Sheet, primarily related to initial margin requirements. Long-term debt. The increase in the estimated fair value and book value of long-term debt reflects the Corporation’s issuance of new debt securities during 2020. The carrying value of these debt securities as of June 30, 2020, is below: Carrying Issuance Date Description of Notes Value (millions of dollars) March 2020 2.992% notes due 2025 1,500 3.294% notes due 2027 1,000 3.482% notes due 2030 2,000 4.227% notes due 2040 1,250 4.327% notes due 2050 2,750 April 2020 1.571% notes due 2023 2,750 2.992% notes due 2025 (1) 1,314 2.610% notes due 2030 2,000 4.227% notes due 2040 (1) 842 3.452% notes due 2051 2,750 June 2020 (2) 0.142% notes due 2024 1,680 0.524% notes due 2028 1,120 0.835% notes due 2032 1,120 1.408% notes due 2039 1,120 Total 23,196 (1) Includes premiums of $ 156 million. (2) Euro-denominated. The Corporation may use non-derivative financial instruments, such as its foreign currency-denominated debt, as hedges of its net investments in certain foreign subsidiaries. Under this method, the change in the carrying value of the financial instruments due to foreign exchange fluctuations is reported in accumulated other comprehensive income. As of June 30, 2020, the Corporation has designated $ 1.9 billion of its Euro-denominated long-term debt as a net investment hedge of its European business. The net investment hedge is deemed to be perfectly effective. The Corporation had undrawn short-term committed lines of credit of $ 15.4 billion and an undrawn long-term committed line of credit of $ 0.2 billion as of second quarter 2020. Derivative Instruments. The Corporation’s size, strong capital structure, geographic diversity and the complementary nature of the Upstream, Downstream and Chemical businesses reduce the Corporation’s enterprise-wide risk from changes in commodity prices, currency rates and interest rates. In addition, the Corporation uses commodity-based contracts, including derivatives, to manage commodity price risk and for trading purposes. Commodity contracts held for trading purposes are presented in the Consolidated Statement of Income on a net basis in the line “Sales and other operating revenue.” The Corporation’s commodity derivatives are not accounted for under hedge accounting. At times, the Corporation also enters into currency and interest rate derivatives, none of which are material to the Corporation’s financial position as of June 30, 2020, and December 31, 2019, or results of operations for the periods ended June 30, 2020, and 2019. Credit risk associated with the Corporation’s derivative position is mitigated by several factors, including the use of derivative clearing exchanges and the quality of and financial limits placed on derivative counterparties. The Corporation maintains a system of controls that includes the authorization, reporting and monitoring of derivative activity. The net notional long/(short) position of derivative instruments at June 30, 2020, and December 31, 2019, was as follows: June 30, Dec. 31, 2020 2019 Crude oil (millions of barrels) ( 32) 57 Petroleum products (millions of barrels) ( 53) ( 38) Natural Gas (MMBTUs) ( 351) ( 165) Realized and unrealized gains/(losses) on derivative instruments that were recognized in the Consolidated Statement of Income are included in the following lines on a before-tax basis: Three Months Ended Six Months Ended June 30, June 30, 2020 2019 2020 2019 (millions of dollars) Sales and other operating revenue ( 251) 33 985 ( 242) Crude oil and product purchases ( 178) 33 ( 530) 15 Total ( 429) 66 455 ( 227)

Allowance For Current Expected Credit Loss (CECL) [Abstract]
Allowance For Current Expected Credit Loss (CECL)	10. Allowance for Current Expected Credit Loss (CECL) Effective January 1, 2020, the Corporation adopted the Financial Accounting Standards Board’s update, Financial Instruments – Credit Losses (Topic 326) , as amended. The standard requires a valuation allowance for credit losses be recognized for certain financial assets that reflects the current expected credit loss over the asset’s contractual life. The valuation allowance considers the risk of loss, even if remote, and considers past events, current conditions and reasonable and supportable forecasts. The standard requires this expected loss methodology for trade receivables, certain other financial assets and off-balance sheet credit exposures. The cumulative effect adjustment related to the adoption of this standard reduced equity by $ 93 million. The Corporation is exposed to credit losses primarily through sales of petroleum products, crude oil, NGLs and natural gas, as well as loans to equity companies and joint venture receivables. A counterparty’s ability to pay is assessed through a credit review process that considers payment terms, the counterparty’s established credit rating or the Corporation’s assessment of the counterparty’s credit worthiness, contract terms, country of operation, and other risks. The Corporation can require prepayment or collateral to mitigate certain credit risks. The Corporation groups financial assets into portfolios that share similar risk characteristics for purposes of determining the allowance for credit losses. Each reporting period, the Corporation assesses whether a significant change in the risk of credit loss has occurred. Among the quantitative and qualitative factors considered are historical financial data, current conditions, industry and country risk, current credit ratings and the quality of third-party guarantees secured from the counterparty. Financial assets are written off in whole, or in part, when practical recovery efforts have been exhausted and no reasonable expectation of recovery exists. Subsequent recoveries of amounts previously written off are recognized in earnings. The Corporation manages receivable portfolios using past due balances as a key credit quality indicator. The Corporation recognizes a credit allowance for off-balance sheet credit exposures as a liability on the balance sheet, separate from the allowance for credit losses related to recognized financial assets. Among these exposures are unfunded loans to equity companies and financial guarantees that cannot be cancelled unilaterally by the Corporation. In the first half of 2020, the COVID-19 pandemic spread through most areas of the world resulting in economic uncertainty, global financial market volatility, and negative effects in the credit markets. The Corporation has considered these effects, along with the significantly lower balances of trade receivables at the end of the quarter, in its estimate of credit losses and concluded no material adjustment to credit allowances in the quarter was required. At June 30, 2020, the Corporation’s evaluation of financial assets under Financial Instruments – Credit Losses (Topic 326) , as amended, included $ 15,519 million of notes and accounts receivable, net of allowances of $ 153 million, and $ 9,434 million of loans and long-term receivables, net of allowances of $ 443 million, and certain other financial assets where there is immaterial risk of loss.

Summary of Accounting Policies

Summary of Accounting Policies (Policy)	6 Months Ended

Summary of Accounting Policies [Abstract]
Inventory Policy	Crude oil, products and merchandise inventories are carried at the lower of current market value or cost, generally determined under the last-in first-out method (LIFO). The earnings impact may be adjusted upward or downward this year based on prevailing market prices at the time of future evaluations. At year-end, any required adjustment is considered permanent and is incorporated into the LIFO carrying value of the inventory.
Legal Costs Policy	The Corporation accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated. 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. The Corporation does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and which are significant, the Corporation discloses the nature of the contingency and, where feasible, an estimate of the possible loss. For purposes of our contingency disclosures, “significant” includes material matters, as well as other matters which management believes should be disclosed.
Net Investment Hedge Risk Management Policy	The Corporation may use non-derivative financial instruments, such as its foreign currency-denominated debt, as hedges of its net investments in certain foreign subsidiaries. Under this method, the change in the carrying value of the financial instruments due to foreign exchange fluctuations is reported in accumulated other comprehensive income.
Credit Loss Financial Instrument Policy	The Corporation groups financial assets into portfolios that share similar risk characteristics for purposes of determining the allowance for credit losses. Each reporting period, the Corporation assesses whether a significant change in the risk of credit loss has occurred. Among the quantitative and qualitative factors considered are historical financial data, current conditions, industry and country risk, current credit ratings and the quality of third-party guarantees secured from the counterparty.
