Summary of Accounting Policies (Policy)	9 Months Ended
Summary of Accounting Policies (Policy)	Sep. 30, 2023
Accounting Policies [Abstract]
Commitments and 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.
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.

Pioneer Natural Resources Merger	9 Months Ended
Pioneer Natural Resources Merger	Sep. 30, 2023
Business Combinations [Abstract]
Pioneer Natural Resources Merger	Denbury AcquisitionOn July 13, 2023, the Corporation entered into an agreement to acquire Denbury Inc., a developer of carbon capture, utilization and storage solutions and enhanced oil recovery in exchange for ExxonMobil common stock. Based on the July 12 closing price for ExxonMobil shares, and at a fixed exchange rate of 0.84 per Denbury share, the transaction value was $4.9 billion. We expect that the number of shares issuable in connection with the transaction to be approximately 45 million. Denbury scheduled a shareholder vote for October 31, 2023, and assuming shareholder approval, the transaction is currently expected to close in early November. In addition to carbon capture and storage assets, the acquisition includes Gulf Coast and Rocky Mountain oil and natural gas operations which consist of proved reserves totaling over 200 million barrels of oil equivalent (as of December 31, 2022), with approximately 47 thousand oil-equivalent barrels per day of production for the first half of 2023.Pioneer Natural Resources Merger On October 11, 2023, the Corporation entered into a merger agreement with Pioneer Natural Resources, an independent oil and gas exploration and production company, in exchange for ExxonMobil common stock. Based on the October 10 closing price for ExxonMobil shares, the fixed exchange rate of 2.3234 per Pioneer share, and Pioneer's outstanding net debt, the implied enterprise value of the transaction was approximately $65 billion. We expect that the number of shares issuable in connection with the transaction to be approximately 546 million. The transaction is currently expected to close in the first half of 2024, subject to regulatory approvals. Pioneer holds over 850,000 net acres in the Midland Basin of West Texas, which consist of proved reserves totaling over 2.3 billion barrels of oil equivalent (as of December 31, 2022) and over 700 thousand oil-equivalent barrels per day of production for the three months ended June 30, 2023.

(1) Included in the Balance Sheet lines: Notes and accounts receivable - net and Other assets, including intangibles - net.
(2) Included in the Balance Sheet line: Investments, advances and long-term receivables.
(3) Included in the Balance Sheet lines: Investments, advances and long-term receivables and Other assets, including intangibles - net.
(4) Included in the Balance Sheet lines: Accounts payable and accrued liabilities and Other long-term obligations.
(5) Excluding finance lease obligations.
(6) Advances to/receivables from equity companies and long-term obligations to equity companies are mainly designated as hierarchy level 3 inputs. The fair value is calculated by discounting the remaining obligations by a rate consistent with the credit quality and industry of the company.
(7) Included in the Balance Sheet line: Other long-term obligations. Includes contingent consideration related to a prior year acquisition where fair value is based on expected drilling activities and discount rates.

At September 30, 2023 and December 31, 2022, respectively, the Corporation had $834 million and $1,494 million of collateral under master netting arrangements not offset against the derivatives on the Condensed Consolidated Balance Sheet, primarily related to initial margin requirements.

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 September 30, 2023, the Corporation has designated $4.8 billion of its Euro-denominated debt and related accrued interest 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 $524 million and undrawn long-term committed lines of credit of $834 million as of third quarter 2023.

Derivative Instruments

The Corporation’s size, strong capital structure, geographic diversity, and the complementary nature of its business segments 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 to generate returns from trading. Commodity contracts held for trading purposes are presented in the Condensed Consolidated Statement of Income on a net basis in the line “Sales and other operating revenue" and in the Consolidated Statement of Cash Flows in “Cash Flows from Operating Activities”. 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 September 30, 2023 and December 31, 2022, or results of operations for the periods ended September 30, 2023 and 2022.

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 September 30, 2023 and December 31, 2022, was as follows:




(millions)	September 30, 2023	December 31, 2022
Crude oil (barrels)	14	4
Petroleum products (barrels)	(95)	(52)
Natural gas (MMBTUs)	(151)	(64)

Realized and unrealized gains/(losses) on derivative instruments that were recognized in the Condensed Consolidated Statement of Income are included in the following lines on a before-tax basis:





(millions of dollars)	Three Months Ended September 30,		Nine Months Ended September 30,
	2023	2022	2023	2022
Sales and other operating revenue	(1,049)	945	(66)	(3,003)
Crude oil and product purchases	34	(56)	14	(82)
Total	(1,015)	889	(52)	(3,085)

Based on the July 12 closing price for ExxonMobil shares, and at a fixed exchange rate of 0.84 per Denbury share, the transaction value was $4.9 billion. We expect that the number of shares issuable in connection with the transaction to be approximately 45 million. Denbury scheduled a shareholder vote for October 31, 2023, and assuming shareholder approval, the transaction is currently expected to close in early November. In addition to carbon capture and storage assets, the acquisition includes Gulf Coast and Rocky Mountain oil and natural gas operations which consist of proved reserves totaling over 200 million barrels of oil equivalent (as of December 31, 2022), with approximately 47 thousand oil-equivalent barrels per day of production for the first half of 2023.Pioneer Natural Resources Merger On October 11, 2023, the Corporation entered into a merger agreement with Pioneer Natural Resources, an independent oil and gas exploration and production company, in exchange for ExxonMobil common stock. Based on the October 10 closing price for ExxonMobil shares, the fixed exchange rate of 2.3234 per Pioneer share, and Pioneer's outstanding net debt, the implied enterprise value of the transaction was approximately $65 billion. We expect that the number of shares issuable in connection with the transaction to be approximately 546 million. The transaction is currently expected to close in the first half of 2024, subject to regulatory approvals. Pioneer holds over 850,000 net acres in the Midland Basin of West Texas, which consist of proved reserves totaling over 2.3 billion barrels of oil equivalent (as of December 31, 2022) and over 700 thousand oil-equivalent barrels per day of production for the three months ended June 30, 2023.

Impairment or Disposal of Tangible Assets Disclosure [Abstract]
Russia	RussiaIn response to Russia’s military action in Ukraine, the Corporation announced in early 2022 that it planned to discontinue operations on the Sakhalin-1 project (“Sakhalin”) and develop steps to exit the venture. In light of this, an impairment assessment was conducted, and management determined that the carrying value of the asset group was not recoverable. As a result, the Corporation’s first-quarter 2022 earnings included after-tax charges of $3.4 billion largely representing the full impairment of its operations related to Sakhalin. On a before-tax basis, the charges amounted to $4.6 billion, substantially all of which is reflected in the line captioned “Depreciation and depletion (includes impairments)” on the Condensed Consolidated Statement of Income. Effective October 14, 2022 the Russian government unilaterally terminated the Corporation’s interests in Sakhalin, transferring operations to a Russian operator. The Corporation’s fourth-quarter 2022 results included an after-tax benefit of $1.1 billion largely reflecting the impact of the expropriation on the company’s various obligations related to Sakhalin. The Corporation's exit from the project resulted in approximately 150 million oil-equivalent barrels no longer qualifying as proved reserves at year-end 2022.

Loss Contingency [Abstract]

Litigation And Other Contingencies

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.

State and local governments and other entities in various jurisdictions across the United States and its territories have filed a number of legal proceedings against several oil and gas companies, including ExxonMobil, requesting unprecedented legal and equitable relief for various alleged injuries purportedly connected to climate change. These lawsuits assert a variety of novel, untested claims under statutory and common law. Additional such lawsuits may be filed. We believe the legal and factual theories set forth in these proceedings are meritless and represent an inappropriate attempt to use the court system to usurp the proper role of policymakers in addressing the societal challenges of climate change.

Local governments in Louisiana have filed unprecedented legal proceedings against a number of oil and gas companies, including ExxonMobil, requesting compensation for the restoration of coastal marshes in the state. We believe the factual and legal theories set forth in these proceedings are meritless.

While the outcome of any litigation can be unpredictable, we believe the likelihood is remote that the ultimate outcomes of these lawsuits will have a material adverse effect on the Corporation’s operations, financial condition, or financial statements taken as a whole. We will continue to defend vigorously against these claims.

Other Contingencies

The Corporation and certain of its consolidated subsidiaries were contingently liable at September 30, 2023, 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. Where it is not possible to make a reasonable estimation of the maximum potential amount of future payments, future performance is expected to be either immaterial or have only a remote chance of occurrence. 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.

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; sanctions 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.

Discontinued Operations and Disposal Groups [Abstract]
Divestment Activities	Divestment Activities Through September 30, 2023, the Corporation realized proceeds of approximately $3.1 billion from its divestment activities in 2023 with negligible impact on net after-tax earnings. This included the sale of the Aera Energy joint venture, Esso Thailand Ltd., the Billings Refinery, certain unconventional assets in the United States, as well as other smaller divestments. In 2022, the Corporation realized proceeds of approximately $5 billion and recognized net after-tax earnings of approximately $0.4 billion from its divestment activities. This included the sale of certain unproved assets in Romania and unconventional assets in Canada and the United States, as well as other smaller divestments. In November 2022, the Corporation executed an agreement for the sale of the Santa Ynez Unit and associated assets in California. The agreement is subject to certain conditions precedent and government approvals and does not yet meet held-for-sale criteria under ASC 360. Should the conditions precedent be met and the potential transaction close, the Corporation would expect to recognize a loss of up to $2 billion. In February 2022, the Corporation signed an agreement with Seplat Energy Offshore Limited for the sale of Mobil Producing Nigeria Unlimited. The agreement is subject to certain conditions precedent and government approvals. In mid-2022, a Nigerian court issued an order to halt transition activities and enter into arbitration with the Nigerian National Petroleum Company. The closing date and any loss on sale will depend on resolution of these matters.
