Pioneer Natural Resources Merger	Mar. 31, 2024
Business Combination and Asset Acquisition [Abstract]
Pioneer Natural Resources Merger	Pioneer Natural Resources Merger On October 11, 2023, the Corporation entered into a merger agreement with Pioneer Natural Resources Company (Pioneer), an independent oil and gas exploration and production company, in exchange for ExxonMobil common stock. Based on the Octob er 5 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 545 million. The transaction is expected to close in the second quarter 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 2.4 billion barrels of oil equivalent (as of December 31, 2023) and over 700 thousand oil-equivalent barrels per day of production for the three months ended December 31, 2023.

Litigation And Other Contingenc

Litigation And Other Contingencies	3 Months Ended
Litigation And Other Contingencies	Mar. 31, 2024
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 marsh erosion 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 March 31, 2024, 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.

Includes contingent consideration related to a prior year acquisition where fair value is based on expected drilling activities and discount rates. At March 31, 2024 and December 31, 2023, respectively, the Corporation had $736 million and $800 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 March 31, 2024, the Corporation has designated $4.9 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 $323 million and undrawn long-term committed lines of credit of $1,914 million as of first quarter 2024. 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 March 31, 2024 and December 31, 2023, or results of operations for the periods ended March 31, 2024 and 2023. 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.

Basis Of Financial Statement Preparation [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.
