New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
Accounting Changes [Text Block]	2 . Accounting Changes Effective January 1, 2018, ExxonMobil adopted the Financial Accounting Standards Board’s standard, Revenue from Contracts with Customers (Topic 606) , as amended. The standard establishes a single revenue recognition model for all contracts with customers, eliminates industry and transaction specific requirements, and expands disclosure requirements. The standard was adopted using the Modified Retrospective method, under which prior year results are not restated, but supplemental information is provided for any mat erial impacts of the standard on 2018 results. The adoption of the standard did not have a material impact on any of the lines reported in the Corporation’s financial statements . The cumulative effect of adoption of the standard was de minimis . The Corporation did not elect any practical expedients that require disclosure. See Note 9. Effective January 1, 2018, ExxonMobil adopted the Financial Accounting Standards Board’s Update, Financial Instruments – Overall (Subtopic 825-10): Recognition and Me asurement of Financial Assets and Financial Liabilities . The standard requires investments in equity securities other than consolidated subsidiaries and equity method investments to be measured at fair value with changes in the fair value recognized throug h net income. The Corporation elected a modified approach for equity securities that do not have a readily determinable fair value. This modified approach measures investments at cost minus impairment, if any, plus or minus changes resulting from observabl e price changes in orderly transactions for the identical or a similar investment of the same issuer. The cumulative effect adjustment related to the adoption o f this standard increased equity $47 million. The portion of unrealized gains and losses recogni zed during the reporting period o n equi ty securities still held at September 30 , 2018 and the carrying value of equity securities without readily determinable fair values at September 30, 2018 were not significant to the Corporation. The standard also expanded discl osures related to financial instruments . S ee Note 7. Effective January 1, 2018, ExxonMobil adopted the Financial Accounting Standards Board’s Update, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost . The update requires separate presentation of the service cost component from other components of net benefit costs. The other components are reported in a new line on the Corporation’s Statement of Income, “Non-service pension and postretirement benefit expense.” The Corporation elected to use the practical expedient which uses the amounts disclosed in the pension and other postretirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentatio n requirements, as it is impracticable to determine the amounts capitalized in those periods. Beginning in 2018, the other components of net benefit costs are included in the Corporate and financing segment. The estimated after-tax impact from the change i n segmentation is an increase in Corporate and financing expenses of about $ 100 million for the third quarter and $ 300 million for the first nine months of 2018. The increase in the Corporate and financing expenses is offset by lower expenses across the op erating segments. Additionally, only the service cost component of net benefit costs is eligible for capitalization in situations where it is otherwise appropriate to capitalize employee costs in connection with the construction or production of an asset. The impact of the retrospective prese ntation change on ExxonMobil's Consolidated Statement of I ncome for the three months and nine months ended September 30, 2017 , is shown below. Three Months Ended Nine Months Ended September 30, 2017 September 30, 2017 As Reported Change As Adjusted As Reported Change As Adjusted (millions of dollars) Production and manufacturing expenses 8,334 (382) 7,952 24,586 (1,008) 23,578 Selling, general and administrative expenses 2,725 (93) 2,632 7,952 (259) 7,693 Non-service pension and postretirement benefit expense - 475 475 - 1,267 1,267 Effective January 1, 2019, ExxonMobil will adopt the Financial Accounting Standards Board’s standard, Leases (Topic 842) , as amended. The standard requires all leases with an initial term greater than one year to be recorded on the balance sheet as a right of use asset and a lease liability. We expect to use a transition method that applies the new lease standard at January 1, 2019 , and recognizes a ny cumulative-effect adjustment s to the opening balance of 2019 retained earnings. The Corporation acq uired lease accounting software to facilitate implementation, and is currently configuring and testing the software. Based on leases outstanding at the end of 2017, the Corporation estimates the operating lease right of use asset and lease liability would have been in the range of $ 4 billion to $ 5 billion at that time. The effect on the Corporation’s balance sheet as a result of implementing the standard on January 1, 2019, could differ considerably depending on operating leases commenced in 2018 as well as interest rates and other factors such as the expiry or ren ewal of leases during the year.

Litigation And Other Contingencies [Abstract]
Litigation And Other Contingencies	3 . Litigation and Other Contingencies Litig ation 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 b ut 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 o f 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 up on 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 September 30, 2018 , 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 C orporation’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. As of September 30, 2018 Equity Other Company Third Party Obligations (1) Obligations Total (millions of dollars) Guarantees Debt-related 461 63 524 Other 1,008 4,046 5,054 Total 1,469 4,109 5,578 (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 fo rced 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 occ urrences 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 refu sed 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 rule s 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 I CSID on September 26, 2018. The net impact of th is 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 opera tions 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 oper ator 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 Contract ors 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 aw ard. 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 Nige rian federal high court in order to preserve their ability to seek enforcement of the PSC in the courts if necessary. F ollowing 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 to enforce , if necessary, the arb itration award against NNPC assets residing within that jurisdiction. NNPC has moved to dismiss the lawsuit. 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.

Revenue Recognition [Abstract]
Revenue Recognition [Text Block]	9. Addi tional Information on Revenue Recognition Accounting Policy for Revenue Recognition The Corporation generally sells crude oil, natural gas and petroleum and chemical products under short-term agreements at prevailing market prices. In some cases (e.g., natural gas), products may be sold under long-term agreements, with periodic price adjustments to reflect market conditions . Revenue is recognized at the amount the Corporation expects to receive when the customer has taken control, which is typically when title transfers and the customer has ass umed the risks and rewards of ownership. The prices of certain sales are based on price indexes that are sometimes not a vailable until the next period. In such cases, estimated realizations are accrued when the sale is recognized, and are finalized when th e price is available. Such adjustments to revenue from performance obligations satisfied in previous periods are not significant. Payment for revenue transactions is typically due within 30 days. Future volume delivery obligations that are unsatisfied at t he end of the period are expected to be fulfilled through o rdinary production or purchases. T hese performance obligations are based on market prices at the time of the transaction and are fully constrained due to market price volatility. “Sales and other operating revenue” and “Notes and accounts receivable” primarily arise from contracts with customers. Long-term receivables are primarily from non-customers. Contract a ssets are mainly from marketing assistance programs and are not significant. Contract li abilities are mainly customer prepayments and accruals of expected volume discounts and are not significant.
