Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies General The company’s Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America. These require the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto, including discussion and disclosure of contingent liabilities. Although the company uses its best estimates and judgments, actual results could differ from these estimates as circumstances change and additional information becomes known. Subsidiary and Affiliated Companies The Consolidated Financial Statements include the accounts of controlled subsidiary companies more than 50 percent-owned and any variable interest entities in which the company is the primary beneficiary. Undivided interests in oil and gas joint ventures and certain other assets are consolidated on a proportionate basis. Investments in and advances to affiliates in which the company has a substantial ownership interest of approximately 20 percent to 50 percent, or for which the company exercises significant influence but not control over policy decisions, are accounted for by the equity method. Investments in affiliates are assessed for possible impairment when events indicate that the fair value of the investment may be below the company’s carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in net income. In making the determination as to whether a decline is other than temporary, the company considers such factors as the duration and extent of the decline, the investee’s financial performance, and the company’s ability and intention to retain its investment for a period that will be sufficient to allow for any anticipated recovery in the investment’s market value. The new cost basis of investments in these equity investees is not changed for subsequent recoveries in fair value. Differences between the company’s carrying value of an equity investment and its underlying equity in the net assets of the affiliate are assigned to the extent practicable to specific assets and liabilities based on the company’s analysis of the various factors giving rise to the difference. When appropriate, the company’s share of the affiliate’s reported earnings is adjusted quarterly to reflect the difference between these allocated values and the affiliate’s historical book values. Noncontrolling Interests Ownership interests in the company’s subsidiaries held by parties other than the parent are presented separately from the parent’s equity on the Consolidated Balance Sheet. The amount of consolidated net income attributable to the parent and the noncontrolling interests are both presented on the face of the Consolidated Statement of Income and Consolidated Statement of Equity. Included within noncontrolling interest is redeemable noncontrolling interest. Fair Value Measurements The three levels of the fair value hierarchy of inputs the company uses to measure the fair value of an asset or a liability are as follows. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included within Level 1 that are directly or indirectly observable for the asset or liability. Level 3 inputs are inputs that are not observable in the market. Derivatives The majority of the company’s activity in derivative commodity instruments is intended to manage the financial risk posed by physical transactions. For some of this derivative activity, the company may elect to apply fair value or cash flow hedge accounting with changes in fair value recorded as components of accumulated other comprehensive income (loss). For other similar derivative instruments, generally because of the short-term nature of the contracts or their limited use, the company does not apply hedge accounting, and changes in the fair value of those contracts are reflected in current income. For the company’s commodity trading activity, gains and losses from derivative instruments are reported in current income. The company may enter into interest rate swaps from time to time as part of its overall strategy to manage the interest rate risk on its debt. Interest rate swaps related to a portion of the company’s fixed-rate debt, if any, may be accounted for as fair value hedges. Interest rate swaps related to floating-rate debt, if any, are recorded at fair value on the balance sheet with resulting gains and losses reflected in income. Where Chevron is a party to master netting arrangements, fair value receivable and payable amounts recognized for derivative instruments executed with the same counterparty are generally offset on the balance sheet. Inventories Crude oil, petroleum products and chemicals inventories are generally stated at cost, using a last-in, first-out method. In the aggregate, these costs are below market. “Materials, supplies and other” inventories are primarily stated at cost or net realizable value. Properties, Plant and Equipment The successful efforts method is used for crude oil and natural gas exploration and production activities. All costs for development wells, related plant and equipment, proved mineral interests in crude oil and natural gas properties, and related asset retirement obligation (ARO) assets are capitalized. Costs of exploratory wells are capitalized pending determination of whether the wells found proved reserves. Costs of wells that are assigned proved reserves remain capitalized. Costs also are capitalized for exploratory wells that have found crude oil and natural gas reserves even if the reserves cannot be classified as proved when the drilling is completed, provided the exploratory well has found a sufficient quantity of reserves to justify its completion as a producing well and the company is making sufficient progress assessing the reserves and the economic and operating viability of the project. All other exploratory wells and costs are expensed. Refer to Note 21 Accounting for Suspended Exploratory Wells for additional discussion of accounting for suspended exploratory well costs. Long-lived assets to be held and used, including proved crude oil and natural gas properties, are assessed for possible impairment by comparing their carrying values with their associated undiscounted, future net cash flows. Events that can trigger assessments for possible impairments include write-downs of proved reserves based on field performance, significant decreases in the market value of an asset (including changes to the commodity price forecast or carbon costs), significant change in the extent or manner of use of or a physical change in an asset, and a more-likely-than-not expectation that a long-lived asset or asset group will be sold or otherwise disposed of significantly sooner than the end of its previously estimated useful life. Impaired assets are written down to their estimated fair values, generally their discounted, future net cash flows. For proved crude oil and natural gas properties, the company performs impairment reviews on a country, concession, PSC, development area or field basis, as appropriate. In Downstream, impairment reviews are performed on the basis of a refinery, a plant, a marketing/lubricants area or distribution area, as appropriate. Impairment amounts are recorded as incremental “Depreciation, depletion and amortization” expense. Long-lived assets that are held for sale are evaluated for possible impairment by comparing the carrying value of the asset with its fair value less the cost to sell. If the net book value exceeds the fair value less cost to sell, the asset is considered impaired and adjusted to the lower value. Refer to Note 9 Fair Value Measurements relating to fair value measurements. The fair value of a liability for an ARO is recorded as an asset and a liability when there is a legal obligation associated with the retirement of a long-lived asset and the amount can be reasonably estimated. Refer also to Note 25 Asset Retirement Obligations relating to AROs. Depreciation and depletion of all capitalized costs of proved crude oil and natural gas producing properties, except mineral interests, are expensed using the unit-of-production method, generally by individual field, as the proved developed reserves are produced. Depletion expenses for capitalized costs of proved mineral interests are recognized using the unit-of-production method by individual field as the related proved reserves are produced. Impairments of capitalized costs of unproved mineral interests are expensed. The capitalized costs of all other plant and equipment are depreciated or amortized over their estimated useful lives. In general, the declining-balance method is used to depreciate plant and equipment in the United States; the straight-line method is generally used to depreciate international plant and equipment and to amortize finance lease right-of-use assets. Gains or losses are not recognized for normal retirements of properties, plant and equipment subject to composite group amortization or depreciation. Gains or losses from abnormal retirements are recorded as expenses, and from sales as “Other income.” Expenditures for maintenance (including those for planned major maintenance projects), repairs and minor renewals to maintain facilities in operating condition are generally expensed as incurred. Major replacements and renewals are capitalized. Leases Leases are classified as operating or finance leases. Both operating and finance leases recognize lease liabilities and associated right-of-use assets. The company has elected the short-term lease exception and therefore only recognizes right-of-use assets and lease liabilities for leases with a term greater than one year. The company has elected the practical expedient to not separate non-lease components from lease components for most asset classes except for certain asset classes that have significant non-lease (i.e., service) components. Where leases are used in joint ventures, the company recognizes 100 percent of the right-of-use assets and lease liabilities when the company is the sole signatory for the lease (in most cases, where the company is the operator of a joint venture). Lease costs reflect only the costs associated with the operator’s working interest share. The lease term includes the committed lease term identified in the contract, taking into account renewal and termination options that management is reasonably certain to exercise. The company uses its incremental borrowing rate as a proxy for the discount rate based on the term of the lease unless the implicit rate is available. Goodwill Goodwill resulting from a business combination is not subject to amortization. The company tests such goodwill at the reporting unit level for impairment annually at December 31, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount. Environmental Expenditures Environmental expenditures that relate to ongoing operations or to conditions caused by past operations are expensed. Expenditures that create future benefits or contribute to future revenue generation are capitalized. Liabilities related to future remediation costs are recorded when environmental assessments or cleanups or both are probable and the costs can be reasonably estimated. For crude oil, natural gas and mineral-producing properties, a liability for an ARO is made in accordance with accounting standards for asset retirement and environmental obligations. Refer to Note 25 Asset Retirement Obligations for a discussion of the company’s AROs. For U.S. federal Superfund sites and analogous sites under state laws, the company records a liability for its designated share of the probable and estimable costs, and probable amounts for other potentially responsible parties when mandated by the regulatory agencies because the other parties are not able to pay their respective shares. The gross amount of environmental liabilities is based on the company’s best estimate of future costs using currently available technology and applying current regulations and the company’s own internal environmental policies. Future amounts are not discounted. Recoveries or reimbursements are recorded as assets when receipt is reasonably assured. Currency Translation The U.S. dollar is the functional currency for substantially all of the company’s consolidated operations and those of its equity affiliates. For those operations, all gains and losses from currency remeasurement are included in current period income. The cumulative translation effects for those few entities, both consolidated and affiliated, using functional currencies other than the U.S. dollar are included in “Currency translation adjustment” on the Consolidated Statement of Equity. Revenue Recognition The company accounts for each delivery order of crude oil, natural gas, petroleum and chemical products as a separate performance obligation. Revenue is recognized when the performance obligation is satisfied, which typically occurs at the point in time when control of the product transfers to the customer. Payment is generally due within 30 days of delivery. The company accounts for delivery transportation as a fulfillment cost, not a separate performance obligation, and recognizes these costs as an operating expense in the period when revenue for the related commodity is recognized. Revenue is measured as the amount the company expects to receive in exchange for transferring commodities to the customer. The company’s commodity sales are typically based on prevailing market-based prices and may include discounts and allowances. Until market prices become known under terms of the company’s contracts, the transaction price included in revenue is based on the company’s estimate of the most likely outcome. Discounts and allowances are estimated using a combination of historical and recent data trends. When deliveries contain multiple products, an observable standalone selling price is generally used to measure revenue for each product. The company includes estimates in the transaction price only to the extent that a significant reversal of revenue is not probable in subsequent periods. Stock Options and Other Share-Based Compensation The company issues stock options and other share-based compensation to certain employees. For equity awards, such as stock options, total compensation cost is based on the grant date fair value, and for liability awards, such as stock appreciation rights, total compensation cost is based on the settlement value. The company recognizes stock-based compensation expense for all awards over the service period required to earn the award, which is the shorter of the vesting period or the time period in which an employee becomes eligible to retain the award at retirement. The company’s Long-Term Incentive Plan (LTIP) awards include stock options and stock appreciation rights, which have graded vesting provisions by which one-third of each award vests on each of the first, second and third anniversaries of the date of grant. In addition, performance shares granted under the company’s LTIP will vest at the end of the three

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The tables below show the fair value hierarchy for assets and liabilities measured at fair value on a recurring and nonrecurring basis at December 31, 2021 and December 31, 2020. Marketable Securities The company calculates fair value for its marketable securities based on quoted market prices for identical assets. The fair values reflect the cash that would have been received if the instruments were sold at December 31, 2021. Derivatives The company records most of its derivative instruments – other than any commodity derivative contracts that are accounted for as normal purchase and normal sale – on the Consolidated Balance Sheet at fair value, with the offsetting amount to the Consolidated Statement of Income. The company designates certain derivative instruments as cash flow hedges that, if applicable, are reflected in the table below. Derivatives classified as Level 1 include futures, swaps and options contracts traded in active markets such as the New York Mercantile Exchange. Derivatives classified as Level 2 include swaps, options and forward contracts principally with financial institutions and other oil and gas companies, the fair values of which are obtained from third-party broker quotes, industry pricing services and exchanges. The company obtains multiple sources of pricing information for the Level 2 instruments. Since this pricing information is generated from observable market data, it has historically been very consistent. The company does not materially adjust this information. Properties, Plant and Equipment The company did not have any individually material impairments in 2021. The company reported impairments for certain upstream properties in 2020 primarily due to downward revisions to its oil and gas price outlook. Investments and Advances In 2021, the company did not have any material impairments of investments and advances measured at fair value on a nonrecurring basis.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial and Derivative Instruments	Financial and Derivative Instruments Derivative Commodity Instruments The company’s derivative commodity instruments principally include crude oil, natural gas, liquefied natural gas and refined product futures, swaps, options, and forward contracts. The company applies cash flow hedge accounting to certain commodity transactions, where appropriate, to manage the market price risk associated with forecasted sales of crude oil. The company’s derivatives are not material to the company’s financial position, results of operations or liquidity. The company believes it has no material market or credit risks to its operations, financial position or liquidity as a result of its commodity derivative activities. The company uses derivative commodity instruments traded on the New York Mercantile Exchange and on electronic platforms of the Inter-Continental Exchange and Chicago Mercantile Exchange. In addition, the company enters into swap contracts and option contracts principally with major financial institutions and other oil and gas companies in the “over-the-counter” markets, which are governed by International Swaps and Derivatives Association agreements and other master netting arrangements. Depending on the nature of the derivative transactions, bilateral collateral arrangements may also be required. Derivative instruments measured at fair value at December 31, 2021, 2020 and 2019, and their classification on the Consolidated Balance Sheet below and Consolidated Statement of Income on the following page: Consolidated Balance Sheet: Fair Value of Derivatives At December 31 Type of Contract Balance Sheet Classification 2021 2020 Commodity Accounts and notes receivable, net $ 251 $ 73 Commodity Long-term receivables, net 62 1 Total assets at fair value $ 313 $ 74 Commodity Accounts payable $ 71 $ 172 Commodity Deferred credits and other noncurrent obligations 1 1 Total liabilities at fair value $ 72 $ 173 Consolidated Statement of Income: The Effect of Derivatives Gain/(Loss) Type of Derivative Statement of Year ended December 31 Contract Income Classification 2021 2020 2019 Commodity Sales and other operating revenues $ (685) $ 69 $ (291) Commodity Purchased crude oil and products (64) (36) (17) Commodity Other income (46) 7 (2) $ (795) $ 40 $ (310) All designated cash flow hedges during the year were settled by December 31, 2021.

Segment Reporting [Abstract]
Operating Segments and Geographic Data	Operating Segments and Geographic Data Although each subsidiary of Chevron is responsible for its own affairs, Chevron Corporation manages its investments in these subsidiaries and their affiliates. The investments are grouped into two business segments, Upstream and Downstream, representing the company’s “reportable segments” and “operating segments.” Upstream operations consist primarily of exploring for, developing, producing and transporting crude oil and natural gas; liquefaction, transportation and regasification associated with liquefied natural gas (LNG); transporting crude oil by major international oil export pipelines; processing, transporting, storage and marketing of natural gas; and a gas-to-liquids plant. Downstream operations consist primarily of refining of crude oil into petroleum products; marketing of crude oil, refined products, and lubricants; manufacturing and marketing of renewable fuels; transporting of crude oil and refined products by pipeline, marine vessel, motor equipment and rail car; and manufacturing and marketing of commodity petrochemicals, plastics for industrial uses, and fuel and lubricant additives. All Other activities of the company include worldwide cash management and debt financing activities, corporate administrative functions, insurance operations, real estate activities, and technology activities. The company’s segments are managed by “segment managers” who report to the “chief operating decision maker” (CODM). The segments represent components of the company that engage in activities (a) from which revenues are earned and expenses are incurred; (b) whose operating results are regularly reviewed by the CODM, which makes decisions about resources to be allocated to the segments and assesses their performance; and (c) for which discrete financial information is available. The company’s primary country of operation is the United States of America, its country of domicile. Other components of the company’s operations are reported as “International” (outside the United States). Segment Earnings The company evaluates the performance of its operating segments on an after-tax basis, without considering the effects of debt financing interest expense or investment interest income, both of which are managed by the company on a worldwide basis. Corporate administrative costs are not allocated to the operating segments. However, operating segments are billed for the direct use of corporate services. Non-billable costs remain at the corporate level in “All Other.” Earnings by major operating area are presented in the following table: Year ended December 31 2021 2020 2019 Upstream United States $ 7,319 $ (1,608) $ (5,094) International 8,499 (825) 7,670 Total Upstream 15,818 (2,433) 2,576 Downstream United States 2,389 (571) 1,559 International 525 618 922 Total Downstream 2,914 47 2,481 Total Segment Earnings 18,732 (2,386) 5,057 All Other Interest expense (662) (658) (761) Interest income 36 52 181 Other (2,481) (2,551) (1,553) Net Income (Loss) Attributable to Chevron Corporation $ 15,625 $ (5,543) $ 2,924 Segment Assets Segment assets do not include intercompany investments or receivables.

Descriptions of major affiliates and non-equity investments, including significant differences between the company’s carrying value of its investments and its underlying equity in the net assets of the affiliates, are as follows: Tengizchevroil Chevron has a 50 percent equity ownership interest in Tengizchevroil (TCO), which operates the Tengiz and Korolev crude oil fields in Kazakhstan. At December 31, 2021, the company’s carrying value of its investment in TCO was about $100 higher than the amount of underlying equity in TCO’s net assets. This difference results from Chevron acquiring a portion of its interest in TCO at a value greater than the underlying book value for that portion of TCO’s net assets. Included in the investment is a loan to TCO to fund the development of the FGP/WPMP with a balance of $4,500. Petropiar Chevron has a 30 percent interest in Petropiar, a joint stock company which operates the heavy oil Huyapari Field and upgrading project in Venezuela’s Orinoco Belt. In 2020, the company fully impaired its investments in the Petropiar affiliate and, effective July 1, 2020, began accounting for this venture as a non-equity method investment. Petroboscan Chevron has a 39.2 percent interest in Petroboscan, a joint stock company which operates the Boscan Field in Venezuela. In 2020, the company fully impaired its investments in the Petroboscan affiliate and, effective July 1, 2020, began accounting for this venture as a non-equity method investment. The company also has an outstanding long-term loan to Petroboscan of $560, which has been fully provisioned for at year-end 2021. Caspian Pipeline Consortium Chevron has a 15 percent interest in the Caspian Pipeline Consortium, which provides the critical export route for crude oil from both TCO and Karachaganak. Angola LNG Limited Chevron has a 36.4 percent interest in Angola LNG Limited, which processes and liquefies natural gas produced in Angola for delivery to international markets. Chevron Phillips Chemical Company LLC Chevron owns 50 percent of Chevron Phillips Chemical Company LLC. The other half is owned by Phillips 66. GS Caltex Corporation Chevron owns 50 percent of GS Caltex Corporation, a joint venture with GS Energy in South Korea. The joint venture imports, refines and markets petroleum products, petrochemicals and lubricants.

Litigation

Litigation	12 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Litigation	Litigation Ecuador Texaco Petroleum Company (Texpet), a subsidiary of Texaco Inc., was a minority member of an oil production consortium with Ecuadorian state-owned Petroecuador from 1967 until 1992. After termination of the consortium and a third-party environmental audit, Ecuador and the consortium parties entered into a settlement agreement specifying Texpet’s remediation obligations. Following Texpet’s completion of a three In February 2011, Chevron sued the Lago Agrio plaintiffs and several of their lawyers and supporters in the U.S. District Court for the Southern District of New York (SDNY) for violations of the Racketeer Influenced and Corrupt Organizations (RICO) Act and state law. The SDNY court ruled that the Ecuadorian judgment had been procured through fraud, bribery, and corruption, and prohibited the RICO defendants from seeking to enforce the Ecuadorian judgment in the United States or profiting from their illegal acts. The Court of Appeals for the Second Circuit affirmed, and the U.S. Supreme Court denied certiorari in June 2017, rendering final the U.S. judgment in favor of Chevron. The Lago Agrio plaintiffs sought to have the Ecuadorian judgment recognized and enforced in Canada, Brazil, and Argentina. All of those recognition and enforcement actions were dismissed and resolved in Chevron’s favor. Chevron and Texpet filed an arbitration claim against Ecuador in September 2009 before an arbitral tribunal administered by the Permanent Court of Arbitration in The Hague, under the United States-Ecuador Bilateral Investment Treaty. In August 2018, the Tribunal issued an award holding that the Ecuadorian judgment was based on environmental claims that Ecuador had settled and released, and that it was procured through fraud, bribery, and corruption. According to the Tribunal, the Ecuadorian judgment “violates international public policy” and “should not be recognized or enforced by the courts of other States.” The Tribunal ordered Ecuador to remove the status of enforceability from the Ecuadorian judgment and to compensate Chevron for any injuries resulting from the judgment. The third and final phase of the arbitration, to determine the amount of compensation Ecuador owes to Chevron, is ongoing. In September 2020, the District Court of The Hague denied Ecuador’s request to set aside the Tribunal’s award, stating that it now is “common ground” between Ecuador and Chevron that the Ecuadorian judgment is fraudulent. In December 2020, Ecuador appealed the District Court’s decision to The Hague Court of Appeals. In a separate proceeding, Ecuador also admitted that the Ecuadorian judgment is fraudulent in a public filing with the Office of the United States Trade Representative in July 2020. Management continues to believe that the Ecuadorian judgment is illegitimate and unenforceable and will vigorously defend against any further attempts to have it recognized or enforced. Climate Change Governmental and other entities in various jurisdictions across the United States have filed legal proceedings against fossil fuel producing companies, including Chevron entities, purporting to seek legal and equitable relief to address alleged impacts of climate change. Chevron entities are or were among the codefendants in 21 separate lawsuits brought by 17 U.S. cities and counties, two U.S. states, the District of Columbia and a trade group. One of the city lawsuits was dismissed on the merits, and one of the county lawsuits was voluntarily dismissed by the plaintiff. The lawsuits assert various causes of action, including public nuisance, private nuisance, failure to warn, design defect, product defect, trespass, negligence, impairment of public trust, and violations of consumer protection statutes, based upon the company’s production of oil and gas products and alleged misrepresentations or omissions relating to climate change risks associated with those products. The unprecedented legal theories set forth in these proceedings entail the possibility of damages liability (both compensatory and punitive), injunctive and other forms of equitable relief, including without limitation abatement and disgorgement of profits, civil penalties and liability for fees and costs of suits, that, while we believe remote, could have a material adverse effect on the company’s results of operations and financial condition. Further such proceedings are likely to be filed by other parties. Management believes that these proceedings are legally and factually meritless and detract from constructive efforts to address the important policy issues presented by climate change, and will vigorously defend against such proceedings. Louisiana Seven coastal parishes and the State of Louisiana have filed lawsuits in Louisiana against numerous oil and gas companies seeking damages for coastal erosion in or near oil fields located within Louisiana’s coastal zone under Louisiana’s State and Local Coastal Resources Management Act (SLCRMA). Chevron entities are defendants in 39 of these cases. The lawsuits allege that the defendants’ historical operations were conducted without necessary permits or failed to comply with permits obtained and seek damages and other relief, including the costs of restoring coastal wetlands allegedly impacted by oil field operations. Plaintiffs’ SLCRMA theories are unprecedented; thus, there remains significant uncertainty about the scope of the claims and alleged damages and any potential effects on the company’s results of operations and financial condition. Management believes that the claims lack legal and factual merit and will continue to vigorously defend against such proceedings.

Taxes	Taxes Income Taxes Year ended December 31 2021 2020 2019 Income tax expense (benefit) U.S. federal Current $ 174 $ (182) $ (73) Deferred 1,004 (1,315) (1,074) State and local Current 222 65 153 Deferred 202 (152) (172) Total United States 1,602 (1,584) (1,166) International Current 4,854 1,833 4,577 Deferred (506) (2,141) (720) Total International 4,348 (308) 3,857 Total income tax expense (benefit) $ 5,950 $ (1,892) $ 2,691 The reconciliation between the U.S. statutory federal income tax rate and the company’s effective income tax rate is detailed in the following table: 2021 2020 2019 Income (loss) before income taxes United States $ 9,674 $ (5,700) $ (5,483) International 11,965 (1,753) 11,019 Total income (loss) before income taxes 21,639 (7,453) 5,536 Theoretical tax (at U.S. statutory rate of 21% ) 4,544 (1,565) 1,163 Effect of U.S. tax reform — — 3 Equity affiliate accounting effect (890) 211 (687) Effect of income taxes from international operations 2,692 (39) 2,196 State and local taxes on income, net of U.S. federal income tax benefit 216 (65) (18) Prior year tax adjustments, claims and settlements 1 362 (236) 192 Tax credits (173) (33) (18) Other U.S. 1, 2 (801) (165) (140) Total income tax expense (benefit) $ 5,950 $ (1,892) $ 2,691 Effective income tax rate 27.5 % 25.4 % 48.6 % 1 Includes one-time tax costs (benefits) associated with changes in uncertain tax positions. 2 Includes one-time tax costs (benefits) associated with changes in valuation allowances (2021 - $(624); 2020 - $0; 2019 - $0). The 2021 increase in income tax expense of $7,842 is a result of the year-over-year increase in total income before income tax expense, which is primarily due to higher upstream realizations, the absence of 2020 impairment and write-offs and higher downstream margins. The company’s effective tax rate changed from 25.4 percent in 2020 to 27.5 percent in 2021. The change in effective tax rate is mainly due to mix effects resulting from the absolute level of earnings or losses and whether they arose in higher or lower tax rate jurisdictions. The company records its deferred taxes on a tax-jurisdiction basis. The reported deferred tax balances are composed of the following: At December 31 2021 2020 Deferred tax liabilities Properties, plant and equipment $ 17,169 $ 16,603 Investments and other 4,105 5,617 Total deferred tax liabilities 21,274 22,220 Deferred tax assets Foreign tax credits (11,718) (10,585) Asset retirement obligations/environmental reserves (4,553) (4,721) Employee benefits (3,037) (3,856) Deferred credits (996) (1,056) Tax loss carryforwards (4,175) (6,701) Other accrued liabilities (239) (228) Inventory (289) (633) Operating leases (1,255) (1,234) Miscellaneous (3,657) (3,685) Total deferred tax assets (29,919) (32,699) Deferred tax assets valuation allowance 17,651 17,762 Total deferred taxes, net $ 9,006 $ 7,283 Deferred tax liabilities decreased by $946 from year-end 2020. The decrease to Investments and other was driven by a consolidated subsidiary restructuring, partially offset with an increase to Properties, plant and equipment. Deferred tax assets decreased by $2,780 from year-end 2020. This decrease was primarily related to decreases in tax loss carryforwards for various locations, and employee benefits, partially offset by the increase in foreign tax credits. The overall valuation allowance relates to deferred tax assets for U.S. foreign tax credit carryforwards, tax loss carryforwards and temporary differences. The valuation allowance reduces the deferred tax assets to amounts that are, in management’s assessment, more likely than not to be realized. At the end of 2021, the company had gross tax loss carryforwards of approximately $10,750 and tax credit carryforwards of approximately $993, primarily related to various international tax jurisdictions. Whereas some of these tax loss carryforwards do not have an expiration date, others expire at various times from 2022 through 2040. U.S. foreign tax credit carryforwards of $11,718 will expire between 2022 and 2032. At December 31, 2021 and 2020, deferred taxes were classified on the Consolidated Balance Sheet as follows: At December 31 2021 2020 Deferred charges and other assets $ (5,659) $ (5,286) Noncurrent deferred income taxes 14,665 12,569 Total deferred income taxes, net $ 9,006 $ 7,283 Income taxes are not accrued for unremitted earnings of international operations that have been or are intended to be reinvested indefinitely. The indefinite reinvestment assertion continues to apply for the purpose of determining deferred tax liabilities for U.S. state and foreign withholding tax purposes. U.S. state and foreign withholding taxes are not accrued for unremitted earnings of international operations that have been or are intended to be reinvested indefinitely. Undistributed earnings of international consolidated subsidiaries and affiliates for which no deferred income tax provision has been made for possible future remittances totaled approximately $49,200 at December 31, 2021. This amount represents earnings reinvested as part of the company’s ongoing international business. It is not practicable to estimate the amount of state and foreign taxes that might be payable on the possible remittance of earnings that are intended to be reinvested indefinitely. The company does not anticipate incurring significant additional taxes on remittances of earnings that are not indefinitely reinvested. Uncertain Income Tax Positions The company recognizes a tax benefit in the financial statements for an uncertain tax position only if management’s assessment is that the position is “more likely than not” (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term “tax position” in the accounting standards for income taxes refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods. The following table indicates the changes to the company’s unrecognized tax benefits for the years ended December 31, 2021, 2020 and 2019. The term “unrecognized tax benefits” in the accounting standards for income taxes refers to the differences between a tax position taken or expected to be taken in a tax return and the benefit measured and recognized in the financial statements. Interest and penalties are not included. 2021 2020 2019 Balance at January 1 $ 5,018 $ 4,987 $ 5,070 Foreign currency effects (1) 2 1 Additions based on tax positions taken in current year 194 253 94 Additions for tax positions taken in prior years 218 437 313 Reductions for tax positions taken in prior years (36) (216) (194) Settlements with taxing authorities in current year (18) (429) (78) Reductions as a result of a lapse of the applicable statute of limitations (87) (16) (219) Balance at December 31 $ 5,288 $ 5,018 $ 4,987 Approximately 82 percent of the $5,288 of unrecognized tax benefits at December 31, 2021, would have an impact on the effective tax rate if subsequently recognized. Certain of these unrecognized tax benefits relate to tax carryforwards that may require a full valuation allowance at the time of any such recognition. Tax positions for Chevron and its subsidiaries and affiliates are subject to income tax audits by many tax jurisdictions throughout the world. For the company’s major tax jurisdictions, examinations of tax returns for certain prior tax years had not been completed as of December 31, 2021. For these jurisdictions, the latest years for which income tax examinations had been finalized were as follows: United States – 2013, Nigeria – 2007, Australia – 2009, Kazakhstan – 2012 and Saudi Arabia – 2015. The company engages in ongoing discussions with tax authorities regarding the resolution of tax matters in the various jurisdictions. Both the outcome of these tax matters and the timing of resolution and/or closure of the tax audits are highly uncertain. However, it is reasonably possible that developments on tax matters in certain tax jurisdictions may result in significant increases or decreases in the company’s total unrecognized tax benefits within the next 12 months. Given the number of years that still remain subject to examination and the number of matters being examined in the various tax jurisdictions, the company is unable to estimate the range of possible adjustments to the balance of unrecognized tax benefits. On the Consolidated Statement of Income, the company reports interest and penalties related to liabilities for uncertain tax positions as “Income tax expense.” As of December 31, 2021, accrual benefit of $(76) for anticipated interest and penalty was included on the Consolidated Balance Sheet, compared with accrual benefit of $(95) as of year-end 2020. Income tax expense (benefit) associated with interest and penalties was $19, $(124) and $(3) in 2021, 2020 and 2019, respectively.

Redeemable long-term obligations consist primarily of tax-exempt variable-rate put bonds that are included as current liabilities because they become redeemable at the option of the bondholders during the year following the balance sheet date. The company may periodically enter into interest rate swaps on a portion of its short-term debt. At December 31, 2021, the company had no interest rate swaps on short-term debt. At December 31, 2021, the company had $10,075 in 364-day committed credit facilities with various major banks that enable the refinancing of short-term obligations on a long-term basis. The credit facilities allow the company to convert any amounts outstanding into a term loan for a period of up to one year. This supports commercial paper borrowing and can also be used for general corporate purposes. The company’s practice has been to continually replace expiring commitments with new commitments on substantially the same terms, maintaining levels management believes appropriate. Any borrowings under the facility would be unsecured indebtedness at interest rates based on the London Interbank Offered Rate (LIBOR), or Secured Overnight Financing Rate (SOFR) when LIBOR has permanently or indefinitely ceased or is no longer representative, or an average of base lending rates published by specified banks and on terms reflecting the company’s strong credit rating. No borrowings were outstanding under this facility at December 31, 2021.

In addition to the $2.6 billion in long-term debt that matured in 2021, the company also completed a tender offer in October 2021, with the objective of lowering future interest expenses, and redeemed bonds with a face value of $2.6 billion and a book value of $3.4 billion (including the fair market valuation adjustment for debt acquired in the Noble Energy acquisition), which resulted in an after-tax loss on the extinguishment of debt of $260 million. The company also repaid $1.1 billion of bank loans associated with the NBLX acquisition during 2021.

Accounting for Suspended Exploratory Wells [Abstract]
Accounting for Suspended Exploratory Wells	Accounting for Suspended Exploratory Wells The company continues to capitalize exploratory well costs after the completion of drilling when the well has found a sufficient quantity of reserves to justify completion as a producing well, and the business unit is making sufficient progress assessing the reserves and the economic and operating viability of the project. If either condition is not met or if the company obtains information that raises substantial doubt about the economic or operational viability of the project, the exploratory well would be assumed to be impaired, and its costs, net of any salvage value, would be charged to expense. The following table indicates the changes to the company’s suspended exploratory well costs for the three years ended December 31, 2021: 2021 2020 2019 Beginning balance at January 1 $ 2,512 $ 3,041 $ 3,563 Additions to capitalized exploratory well costs pending the determination of proved reserves 56 28 244 Reclassifications to wells, facilities and equipment based on the determination of proved reserves (425) (102) (500) Capitalized exploratory well costs charged to expense (34) (667) (125) Other * — 212 (141) Ending balance at December 31 $ 2,109 $ 2,512 $ 3,041 * 2020 represents fair value of well costs acquired in the Noble acquisition. 2019 represents property sales. The following table provides an aging of capitalized well costs and the number of projects for which exploratory well costs have been capitalized for a period greater than one year since the completion of drilling. At December 31 2021 2020 2019 Exploratory well costs capitalized for a period of one year or less $ 65 $ 26 $ 214 Exploratory well costs capitalized for a period greater than one year 2,044 2,486 2,827 Balance at December 31 $ 2,109 $ 2,512 $ 3,041 Number of projects with exploratory well costs that have been capitalized for a period greater than one year * 15 17 22 * Certain projects have multiple wells or fields or both. Of the $2,044 of exploratory well costs capitalized for more than one year at December 31, 2021, $1,119 is related to nine projects that had drilling activities underway or firmly planned for the near future. The $925 balance is related to six projects in areas requiring a major capital expenditure before production could begin and for which additional drilling efforts were not underway or firmly planned for the near future. Additional drilling was not deemed necessary because the presence of hydrocarbons had already been established, and other activities were in process to enable a future decision on project development. The projects for the $925 referenced above had the following activities associated with assessing the reserves and the projects’ economic viability: (a) $486 (four projects) – undergoing front-end engineering and design with final investment decision expected within four years; (b) $439 (two projects) – development alternatives under review. While progress was being made on all 15 projects, the decision on the recognition of proved reserves under SEC rules in some cases may not occur for several years because of the complexity, scale and negotiations associated with the projects. More than half of these decisions are expected to occur in the next five years. The $2,044 of suspended well costs capitalized for a period greater than one year as of December 31, 2021, represents 83 exploratory wells in 15 projects. The tables below contain the aging of these costs on a well and project basis: Aging based on drilling completion date of individual wells: Amount Number of wells 2000-2009 $ 312 16 2010-2014 1,146 50 2015-2020 586 17 Total $ 2,044 83 Aging based on drilling completion date of last suspended well in project: Amount Number of projects 2003-2012 $ 341 3 2013-2016 1,318 9 2017-2021 385 3 Total $ 2,044 15

Share-based Payment Arrangement [Abstract]
Stock Options and Other Share-Based Compensation	Stock Options and Other Share-Based Compensation Compensation expense for stock options for 2021, 2020 and 2019 was $60 ($47 after tax), $94 ($74 after tax) and $81 ($64 after tax), respectively. In addition, compensation expense for stock appreciation rights, restricted stock, performance shares and restricted stock units was $701 ($554 after tax), $96 ($76 after tax) and $313 ($266 after tax) for 2021, 2020 and 2019, respectively. No significant stock-based compensation cost was capitalized at December 31, 2021, or December 31, 2020. Cash received in payment for option exercises under all share-based payment arrangements for 2021, 2020 and 2019 was $1,274, $226 and $1,090, respectively. Actual tax benefits realized for the tax deductions from option exercises were $(15), $8 and $43 for 2021, 2020 and 2019, respectively. Cash paid to settle performance shares, restricted stock units and stock appreciation rights was $163, $95 and $119 for 2021, 2020 and 2019, respectively. Cash paid in 2021 included $4 million for Noble awards paid under change-in-control plan provisions. Awards under the Chevron Long-Term Incentive Plan (LTIP) may take the form of, but are not limited to, stock options, restricted stock, restricted stock units, stock appreciation rights, performance shares and nonstock grants. From April 2004 through May 2023, no more than 260 million shares may be issued under the LTIP. For awards issued on or after May 29, 2013, no more than 50 million of those shares may be in a form other than a stock option, stock appreciation right or award requiring full payment for shares by the award recipient. For the major types of awards issued before January 1, 2017, the contractual terms vary between three years for the performance shares and restricted stock units, and 10 years for the stock options and stock appreciation rights. For awards issued after January 1, 2017, contractual terms vary between three years for the performance shares and special restricted stock units, five years for standard restricted stock units and 10 years for the stock options and stock appreciation rights. Forfeitures for performance shares, restricted stock units, and stock appreciation rights are recognized as they occur. Forfeitures for stock options are estimated using historical forfeiture data dating back to 1990. Noble Share-Based Plans (Noble Plans) When Chevron acquired Noble in October 2020, outstanding stock options granted under various Noble Plans were exchanged for Chevron options. These awards retained the same provision as the original Noble Plans. Awards issued may be exercised for up to five years after termination of employment, depending upon the termination type, or the original expiration date, whichever is earlier. Other awards issued under the Noble Plans included restricted stock awards, restricted stock units, and performance shares, which retained the same provisions as the original Noble Plans. Upon termination of employment due to change-in-control, all unvested awards issued under the Noble Plans, including stock options, restricted stock awards, restricted stock units and performance shares become vested on the termination date. If not exercised, awards will expire between 2022 and 2029. Fair Value and Assumptions The fair market values of stock options and stock appreciation rights granted in 2021, 2020 and 2019 were measured on the date of grant using the Black-Scholes option-pricing model, with the following weighted-average assumptions: Year ended December 31 2021 2020 2019 Expected term in years 1 6.8 6.6 6.6 Volatility 2 31.1 % 20.8 % 20.5 % Risk-free interest rate based on zero coupon U.S. treasury note 0.71 % 1.5 % 2.6 % Dividend yield 6.0 % 4.0 % 3.8 % Weighted-average fair value per option granted $ 12.22 $ 13.00 $ 15.82 1 Expected term is based on historical exercise and post-vesting cancellation data. 2 Volatility rate is based on historical stock prices over an appropriate period, generally equal to the expected term. A summary of option activity during 2021 is presented below: Shares (Thousands) Weighted-Average Averaged Remaining Contractual Term (Years) Aggregate Intrinsic Value Outstanding at January 1, 2021 90,150 $ 108.17 Granted 6,948 $ 88.20 Exercised (12,831) $ 99.64 Forfeited (6,868) $ 102.61 Outstanding at December 31, 2021 77,399 $ 108.10 4.17 $ 1,020 Exercisable at December 31, 2021 66,499 $ 109.80 3.45 $ 806 The total intrinsic value (i.e., the difference between the exercise price and the market price) of options exercised during 2021, 2020 and 2019 was $152, $92 and $516, respectively. During this period, the company continued its practice of issuing treasury shares upon exercise of these awards. As of December 31, 2021, there was $57 of total unrecognized before-tax compensation cost related to nonvested share-based compensation arrangements granted under the plan. That cost is expected to be recognized over a weighted-average period of 1.7 years. At January 1, 2021, the number of LTIP performance shares outstanding was equivalent to 4,434,797 shares. During 2021, 2,219,379 performance shares were granted, 1,378,766 shares vested with cash proceeds distributed to recipients and 252,345 shares were forfeited. At December 31, 2021, there were 5,023,065 performance shares outstanding that are payable in cash. The fair value of the liability recorded for these instruments was $683 and was measured using the Monte Carlo simulation method. At January 1, 2021, the number of restricted stock units outstanding was equivalent to 3,303,933 shares. During 2021, 1,381,433 restricted stock units were granted, 111,831 units vested with cash proceeds distributed to recipients and 186,898 units were forfeited. At December 31, 2021, there were 4,386,637 restricted stock units outstanding that are payable in cash. The fair value of the liability recorded for the vested portion of these instruments was $381, valued at the stock price as of December 31, 2021. In addition, outstanding stock appreciation rights that were granted under LTIP totaled approximately 3.4 million equivalent shares as of December 31, 2021. The fair value of the liability recorded for the vested portion of these instruments was $75.

Employee Benefit Plans

Retirement Benefits [Abstract]
Employee Benefit Plans	Employee Benefit Plans The company has defined benefit pension plans for many employees. The company typically prefunds defined benefit plans as required by local regulations or in certain situations where prefunding provides economic advantages. In the United States, all qualified plans are subject to the Employee Retirement Income Security Act (ERISA) minimum funding standard. The company does not typically fund U.S. nonqualified pension plans that are not subject to funding requirements under laws and regulations because contributions to these pension plans may be less economic and investment returns may be less attractive than the company’s other investment alternatives. The company also sponsors other postretirement benefit (OPEB) plans that provide medical and dental benefits, as well as life insurance for some active and qualifying retired employees. The plans are unfunded, and the company and retirees share the costs. For the company’s main U.S. medical plan, the increase to the pre-Medicare company contribution for retiree medical coverage is limited to no more than 4 percent each year. Certain life insurance benefits are paid by the company. The company recognizes the overfunded or underfunded status of each of its defined benefit pension and OPEB plans as an asset or liability on the Consolidated Balance Sheet. The funded status of the company’s pension and OPEB plans for 2021 and 2020 follows: Pension Benefits 2021 2020 Other Benefits U.S. Int’l.

For the year ended December 31, 2020, the increase in benefit obligations was primarily due to actuarial losses caused by lower discount rates used to value the obligations. Amounts recognized on a before-tax basis in “Accumulated other comprehensive loss” for the company’s pension and OPEB plans were $4,979 and $7,278 at the end of 2021 and 2020, respectively.

U.S. Int’l. U.S. Int’l. 2021 2020 2019 Assumptions used to determine benefit obligations: Discount rate 2.8 % 2.8 % 2.4 % 2.4 % 3.1 % 3.2 % 2.9 % 2.6 % 3.2 % Rate of compensation increase 4.5 % 4.1 % 4.5 % 4.0 % 4.5 % 4.0 % N/A N/A N/A Assumptions used to determine net periodic benefit cost: Discount rate for service cost 3.0 % 2.4 % 3.3 % 3.2 % 4.4 % 4.4 % 3.0 % 3.5 % 4.6 % Discount rate for interest cost 1.9 % 2.4 % 2.6 % 3.2 % 3.7 % 4.4 % 2.1 % 3.0 % 4.2 % Expected return on plan assets 6.5 % 3.5 % 6.5 % 4.5 % 6.8 % 5.6 % N/A N/A N/A Rate of compensation increase 4.5 % 4.0 % 4.5 % 4.0 % 4.5 % 4.0 % N/A N/A N/A Expected Return on Plan Assets The company’s estimated long-term rates of return on pension assets are driven primarily by actual historical asset-class returns, an assessment of expected future performance, advice from external actuarial firms and the incorporation of specific asset-class risk factors. Asset allocations are periodically updated using pension plan asset/liability studies, and the company’s estimated long-term rates of return are consistent with these studies. For 2021, the company used an expected long-term rate of return of 6.50 percent for U.S. pension plan assets, which account for 67 percent of the company’s pension plan assets. The market-related value of assets of the main U.S. pension plan used in the determination of pension expense was based on the market values in the three months preceding the year-end measurement date. Management considers the three Discount Rate The discount rate assumptions used to determine the U.S. and international pension and OPEB plan obligations and expense reflect the rate at which benefits could be effectively settled, and are equal to the equivalent single rate resulting from yield curve analysis. This analysis considered the projected benefit payments specific to the company’s plans and the yields on high-quality bonds. The projected cash flows were discounted to the valuation date using the yield curve for the main U.S. pension and OPEB plans. The effective discount rates derived from this analysis were 2.8 percent, 2.4 percent, and 3.1 percent for 2021, 2020, and 2019, respectively, for both the main U.S. pension and OPEB plans. Other Benefit Assumptions For the measurement of accumulated postretirement benefit obligation at December 31, 2021, for the main U.S. OPEB plan, the assumed health care cost-trend rates start with 6.2 percent in 2022 and gradually decline to 4.5 percent for 2031 and beyond. For this measurement at December 31, 2020, the assumed health care cost-trend rates started with 6.1 percent in 2021 and gradually declined to 4.5 percent for 2027 and beyond. Plan Assets and Investment Strategy The fair value measurements of the company’s pension plans for 2021 and 2020 are as follows: U.S. Int’l.

The company’s U.S. and U.K. pension plans comprise 94 percent of the total pension assets. Both the U.S. and U.K. plans have an Investment Committee that regularly meets during the year to review the asset holdings and their returns. To assess the plans’ investment performance, long-term asset allocation policy benchmarks have been established. For the primary U.S. pension plan, the company’s Investment Committee has established the following approved asset allocation ranges: Equities 40–65 percent, Fixed Income 20–40 percent, Real Estate 0–15 percent, Alternative Investments 0–5 percent and Cash 0–25 percent. For the U.K. pension plan, the U.K. Board of Trustees has established the following asset allocation guidelines: Equities 10–30 percent, Fixed Income 55–85 percent, Real Estate 5–15 percent, and Cash 0–5 percent. The other significant international pension plans also have established maximum and minimum asset allocation ranges that vary by plan. Actual asset allocation within approved ranges is based on a variety of factors, including market conditions and illiquidity constraints. To mitigate concentration and other risks, assets are invested across multiple asset classes with active investment managers and passive index funds. Cash Contributions and Benefit Payments In 2021, the company contributed $1,552 and $199 to its U.S. and international pension plans, respectively. In 2022, the company expects contributions to be approximately $1,100 to its U.S. plans and $200 to its international pension plans. Actual contribution amounts are dependent upon investment returns, changes in pension obligations, regulatory environments, tax law changes and other economic factors. Additional funding may ultimately be required if investment returns are insufficient to offset increases in plan obligations. The company anticipates paying OPEB benefits of approximately $150 in 2022; $146 was paid in 2021. The following benefit payments, which include estimated future service, are expected to be paid by the company in the next 10 years: Pension Benefits Other U.S. Int’l. Benefits 2022 $ 826 $ 296 $ 151 2023 982 211 149 2024 1,025 225 146 2025 1,022 232 144 2026 998 245 142 2027-2031 4,640 1,367 682 Employee Savings Investment Plan Eligible employees of Chevron and certain of its subsidiaries participate in the Chevron Employee Savings Investment Plan (ESIP). Compensation expense for the ESIP totaled $252, $281 and $284 in 2021, 2020 and 2019, respectively. Benefit Plan Trusts Prior to its acquisition by Chevron, Texaco established a benefit plan trust for funding obligations under some of its benefit plans. At year-end 2021, the trust contained 14.2 million shares of Chevron treasury stock. The trust will sell the shares or use the dividends from the shares to pay benefits only to the extent that the company does not pay such benefits. The company intends to continue to pay its obligations under the benefit plans. The trustee will vote the shares held in the trust as instructed by the trust’s beneficiaries. The shares held in the trust are not considered outstanding for earnings-per-share purposes until distributed or sold by the trust in payment of benefit obligations. Prior to its acquisition by Chevron, Unocal established various grantor trusts to fund obligations under some of its benefit plans, including the deferred compensation and supplemental retirement plans. At December 31, 2021 and 2020, trust assets of $36 and $36, respectively, were invested primarily in interest-earning accounts. Employee Incentive Plans The Chevron Incentive Plan is an annual cash bonus plan for eligible employees that links awards to corporate, business unit and individual performance in the prior year. Charges to expense for cash bonuses were $1,165, $462 and $826 in 2021, 2020 and 2019, respectively. Chevron also has the LTIP for officers and other regular salaried employees of the company and its subsidiaries who hold positions of significant responsibility. Awards under the LTIP consist of stock options and other share-based compensation that are described in Note 22 Stock Options and Other Share-Based Compensation

Commitments and Contingencies Disclosure [Abstract]
Other Contingencies and Commitments	Other Contingencies and Commitments Income Taxes The company calculates its income tax expense and liabilities quarterly. These liabilities generally are subject to audit and are not finalized with the individual taxing authorities until several years after the end of the annual period for which income taxes have been calculated. Refer to Note 17 Taxes for a discussion of the periods for which tax returns have been audited for the company’s major tax jurisdictions and a discussion for all tax jurisdictions of the differences between the amount of tax benefits recognized in the financial statements and the amount taken or expected to be taken in a tax return. Settlement of open tax years, as well as other tax issues in countries where the company conducts its businesses, are not expected to have a material effect on the consolidated financial position or liquidity of the company and, in the opinion of management, adequate provisions have been made for all years under examination or subject to future examination. Guarantees Indemnifications In the acquisition of Unocal, the company assumed certain indemnities relating to contingent environmental liabilities associated with assets that were sold in 1997. The acquirer of those assets shared in certain environmental remediation costs up to a maximum obligation of $200, which had been reached at December 31, 2009. Under the indemnification agreement, after reaching the $200 obligation, Chevron is solely responsible until April 2022, when the indemnification expires. The environmental conditions or events that are subject to these indemnities must have arisen prior to the sale of the assets in 1997. Long-Term Unconditional Purchase Obligations and Commitments, Including Throughput and Take-or-Pay Agreements The company and its subsidiaries have certain contingent liabilities with respect to long-term unconditional purchase obligations and commitments, including throughput and take-or-pay agreements, some of which may relate to suppliers’ financing arrangements. The agreements typically provide goods and services, such as pipeline and storage capacity, utilities, and petroleum products, to be used or sold in the ordinary course of the company’s business. The aggregate amounts of required payments under throughput and take-or-pay agreements are: 2022 – $1,049; 2023 – $1,106; 2024 – $1,119; 2025 – $1,193; 2026 – $1,223 ; after 2026 – $7,626. The aggregate amount of required payments for other unconditional purchase obligations are: 2022 – $57; 2023 – $257; 2024 – $242; 2025 – $252; 2026 – $200; after 2026 – Environmental The company is subject to loss contingencies pursuant to laws, regulations, private claims and legal proceedings related to environmental matters that are subject to legal settlements or that in the future may require the company to take action to correct or ameliorate the effects on the environment of prior release of chemicals or petroleum substances by the company or other parties. Such contingencies may exist for various operating, closed and divested sites, including, but not limited to, U.S. federal Superfund sites and analogous sites under state laws, refineries, chemical plants, marketing facilities, crude oil fields, and mining sites. Although the company has provided for known environmental obligations that are probable and reasonably estimable, it is likely that the company will continue to incur additional liabilities. The amount of additional future costs are not fully determinable due to such factors as the unknown magnitude of possible contamination, the unknown timing and extent of the corrective actions that may be required, the determination of the company’s liability in proportion to other responsible parties, and the extent to which such costs are recoverable from third parties. These future costs may be material to results of operations in the period in which they are recognized, but the company does not expect these costs will have a material effect on its consolidated financial position or liquidity. Chevron’s environmental reserve as of December 31, 2021, was $960. Included in this balance was $230 related to remediation activities at approximately 145 sites for which the company had been identified as a potentially responsible party under the provisions of the U.S. federal Superfund law or analogous state laws which provide for joint and several liability for all responsible parties. Any future actions by regulatory agencies to require Chevron to assume other potentially responsible parties’ costs at designated hazardous waste sites are not expected to have a material effect on the company’s results of operations, consolidated financial position or liquidity. Of the remaining year-end 2021 environmental reserves balance of $730, $466 is related to the company’s U.S. downstream operations, $50 to its international downstream operations, and $214 to its upstream operations. Liabilities at all sites were primarily associated with the company’s plans and activities to remediate soil or groundwater contamination or both. The company manages environmental liabilities under specific sets of regulatory requirements, which in the United States include the Resource Conservation and Recovery Act and various state and local regulations. No single remediation site at year-end 2021 had a recorded liability that was material to the company’s results of operations, consolidated financial position or liquidity. Refer to Note 25 Asset Retirement Obligations Other Contingencies Chevron receives claims from and submits claims to customers; trading partners; joint venture partners; U.S. federal, state and local regulatory bodies; governments; contractors; insurers; suppliers; and individuals. The amounts of these claims, individually and in the aggregate, may be significant and take lengthy periods to resolve, and may result in gains or losses in future periods.

Asset Retirement Obligation Disclosure [Abstract]
Asset Retirement Obligations	Asset Retirement Obligations The company records the fair value of a liability for an asset retirement obligation (ARO) both as an asset and a liability when there is a legal obligation associated with the retirement of a tangible long-lived asset and the liability can be reasonably estimated. The legal obligation to perform the asset retirement activity is unconditional, even though uncertainty may exist about the timing and/or method of settlement that may be beyond the company’s control. This uncertainty about the timing and/or method of settlement is factored into the measurement of the liability when sufficient information exists to reasonably estimate fair value. Recognition of the ARO includes: (1) the present value of a liability and offsetting asset, (2) the subsequent accretion of that liability and depreciation of the asset, and (3) the periodic review of the ARO liability estimates and discount rates. AROs are primarily recorded for the company’s crude oil and natural gas producing assets. No significant AROs associated with any legal obligations to retire downstream long-lived assets have been recognized, as indeterminate settlement dates for the asset retirements prevent estimation of the fair value of the associated ARO. The company performs periodic reviews of its downstream long-lived assets for any changes in facts and circumstances that might require recognition of a retirement obligation. The following table indicates the changes to the company’s before-tax asset retirement obligations in 2021, 2020 and 2019: 2021 2020 2019 Balance at January 1 $ 13,616 $ 12,832 $ 14,050 Liabilities assumed in the Noble acquisition — 630 — Liabilities incurred 31 10 32 Liabilities settled (1,887) (1,661) (1,694) Accretion expense 616 560 628 Revisions in estimated cash flows 432 1,245 (184) Balance at December 31 $ 12,808 $ 13,616 $ 12,832 In the table above, the amount associated with “Revisions in estimated cash flows” in 2021 primarily reflects increased cost estimates and scope changes to decommission wells, equipment and facilities. The long-term portion of the $12,808 balance at the end of 2021 was $11,611.

Receivables [Abstract]
Financial Instruments - Credit Losses	Financial Instruments - Credit Losses Chevron’s expected credit loss allowance balance was $745 million as of December 31, 2021 and $671 million as of December 31, 2020, with a majority of the allowance relating to non-trade receivable balances. The majority of the company’s receivable balance is concentrated in trade receivables, with a balance of $16.4 billion as of December 31, 2021, which reflects the company’s diversified sources of revenues and is dispersed across the company’s broad worldwide customer base. As a result, the company believes the concentration of credit risk is limited. The company routinely assesses the financial strength of its customers. When the financial strength of a customer is not considered sufficient, alternative risk mitigation measures may be deployed, including requiring prepayments, letters of credit or other acceptable forms of collateral. Once credit is extended and a receivable balance exists, the company applies a quantitative calculation to current trade receivable balances that reflects credit risk predictive analysis, including probability of default and loss given default, which takes into consideration current and forward-looking market data as well as the company’s historical loss data. This statistical approach becomes the basis of the company’s expected credit loss allowance for current trade receivables with payment terms that are typically short-term in nature, with most due in less than 90 days. Chevron’s non-trade receivable balance was $3.4 billion as of December 31, 2021, which includes receivables from certain governments in their capacity as joint venture partners. Joint venture partner balances that are paid as per contract terms or not yet due are subject to the statistical analysis described above while past due balances are subject to additional qualitative management quarterly review. This management review includes review of reasonable and supportable repayment forecasts. Non-trade receivables also include employee and tax receivables that are deemed immaterial and low risk. Loans to equity affiliates and non-equity investees are also considered non-trade and associated allowances of $560 million are included within “Investments and Advances” on the Consolidated Balance Sheet at both December 31, 2021 and December 30, 2020.

Business Combinations [Abstract]
Acquisition of Noble Energy, Inc.	Acquisition of Noble Energy, Inc. On October 5, 2020, the company acquired Noble Energy, Inc., an independent oil and gas exploration and production company. Noble’s principal upstream operations are in the United States, the Eastern Mediterranean and West Africa. Noble’s operations also include an integrated midstream business in the United States. The acquisition of Noble provides the company with low-cost proved reserves, attractive undeveloped resources and cash-generating assets. The aggregate purchase price of Noble was $4,109, with approximately 58 million shares of Chevron common stock issued as consideration in the transaction, representing approximately 3 percent of shares of Chevron common stock outstanding immediately after the acquisition. As part of the transaction, the company recognized long-term debt and finance leases with a fair value of $9,231. The acquisition was accounted for as a business combination under ASC 805, which requires assets acquired and liabilities assumed to be measured at their acquisition date fair values. Provisional fair value measurements were made for acquired assets and liabilities, and adjustments to those measurements may be made in subsequent periods, up to one year from the acquisition date, as information necessary to complete the analysis is obtained. Oil and gas properties were valued using a discounted cash flow approach that incorporated internally generated price assumptions and production profiles together with appropriate operating cost and development cost assumptions. Debt assumed in the acquisition was valued based on observable market prices for Noble’s debt. As a result of measuring the assets acquired and the liabilities assumed at fair value, there was no goodwill or bargain purchase recognized. The following table summarizes the values assigned to assets acquired and liabilities assumed: At October 5, 2020 Current assets $ 1,105 Investments and long-term receivables 1,282 Properties (includes $14,935 for oil and gas properties) 16,703 Other assets 607 Total assets acquired 19,697 Current liabilities 1,829 Long-term debt and finance leases 9,231 Deferred income taxes 2,355 Other liabilities 1,394 Total liabilities assumed 14,809 Noncontrolling interest and redeemable noncontrolling interest 779 Net assets acquired $ 4,109 The following unaudited pro forma summary presents the results of operations as if the acquisition of Noble had occurred January 1, 2019: Year ended December 31 2020 2019 Sales and other operating revenues $ 96,980 $ 144,303 Net income $ (9,890) $ 1,412 The pro forma summary uses estimates and assumptions based on information available at the time. Management believes the estimates and assumptions to be reasonable; however, actual results may differ significantly from this pro forma financial information. The pro forma information does not reflect any synergistic savings that might be achieved from combining the operations and is not intended to reflect the actual results that would have occurred had the companies actually been combined during the periods presented.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
General	General The company’s Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States of America. These require the use of estimates and assumptions that affect the assets, liabilities, revenues and expenses reported in the financial statements, as well as amounts included in the notes thereto, including discussion and disclosure of contingent liabilities. Although the company uses its best estimates and judgments, actual results could differ from these estimates as circumstances change and additional information becomes known.
Subsidiary and Affiliated Companies	Subsidiary and Affiliated Companies The Consolidated Financial Statements include the accounts of controlled subsidiary companies more than 50 percent-owned and any variable interest entities in which the company is the primary beneficiary. Undivided interests in oil and gas joint ventures and certain other assets are consolidated on a proportionate basis. Investments in and advances to affiliates in which the company has a substantial ownership interest of approximately 20 percent to 50 percent, or for which the company exercises significant influence but not control over policy decisions, are accounted for by the equity method. Investments in affiliates are assessed for possible impairment when events indicate that the fair value of the investment may be below the company’s carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in net income. In making the determination as to whether a decline is other than temporary, the company considers such factors as the duration and extent of the decline, the investee’s financial performance, and the company’s ability and intention to retain its investment for a period that will be sufficient to allow for any anticipated recovery in the investment’s market value. The new cost basis of investments in these equity investees is not changed for subsequent recoveries in fair value.
Noncontrolling Interests	Noncontrolling Interests Ownership interests in the company’s subsidiaries held by parties other than the parent are presented separately from the parent’s equity on the Consolidated Balance Sheet. The amount of consolidated net income attributable to the parent and the noncontrolling interests are both presented on the face of the Consolidated Statement of Income and Consolidated Statement of Equity. Included within noncontrolling interest is redeemable noncontrolling interest.
Fair Value Measurements	Fair Value Measurements The three levels of the fair value hierarchy of inputs the company uses to measure the fair value of an asset or a liability are as follows. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are inputs other than quoted prices included within Level 1 that are directly or indirectly observable for the asset or liability. Level 3 inputs are inputs that are not observable in the market.
Derivatives	Derivatives
Inventories	Inventories
Properties, Plant and Equipment	Properties, Plant and Equipment The successful efforts method is used for crude oil and natural gas exploration and production activities. All costs for development wells, related plant and equipment, proved mineral interests in crude oil and natural gas properties, and related asset retirement obligation (ARO) assets are capitalized. Costs of exploratory wells are capitalized pending determination of whether the wells found proved reserves. Costs of wells that are assigned proved reserves remain capitalized. Costs also are capitalized for exploratory wells that have found crude oil and natural gas reserves even if the reserves cannot be classified as proved when the drilling is completed, provided the exploratory well has found a sufficient quantity of reserves to justify its completion as a producing well and the company is making sufficient progress assessing the reserves and the economic and operating viability of the project. All other exploratory wells and costs are expensed. Refer to Note 21 Accounting for Suspended Exploratory Wells for additional discussion of accounting for suspended exploratory well costs. Long-lived assets to be held and used, including proved crude oil and natural gas properties, are assessed for possible impairment by comparing their carrying values with their associated undiscounted, future net cash flows. Events that can trigger assessments for possible impairments include write-downs of proved reserves based on field performance, significant decreases in the market value of an asset (including changes to the commodity price forecast or carbon costs), significant change in the extent or manner of use of or a physical change in an asset, and a more-likely-than-not expectation that a long-lived asset or asset group will be sold or otherwise disposed of significantly sooner than the end of its previously estimated useful life. Impaired assets are written down to their estimated fair values, generally their discounted, future net cash flows. For proved crude oil and natural gas properties, the company performs impairment reviews on a country, concession, PSC, development area or field basis, as appropriate. In Downstream, impairment reviews are performed on the basis of a refinery, a plant, a marketing/lubricants area or distribution area, as appropriate. Impairment amounts are recorded as incremental “Depreciation, depletion and amortization” expense. Long-lived assets that are held for sale are evaluated for possible impairment by comparing the carrying value of the asset with its fair value less the cost to sell. If the net book value exceeds the fair value less cost to sell, the asset is considered impaired and adjusted to the lower value. Refer to Note 9 Fair Value Measurements relating to fair value measurements. The fair value of a liability for an ARO is recorded as an asset and a liability when there is a legal obligation associated with the retirement of a long-lived asset and the amount can be reasonably estimated. Refer also to Note 25 Asset Retirement Obligations relating to AROs. Depreciation and depletion of all capitalized costs of proved crude oil and natural gas producing properties, except mineral interests, are expensed using the unit-of-production method, generally by individual field, as the proved developed reserves are produced. Depletion expenses for capitalized costs of proved mineral interests are recognized using the unit-of-production method by individual field as the related proved reserves are produced. Impairments of capitalized costs of unproved mineral interests are expensed. The capitalized costs of all other plant and equipment are depreciated or amortized over their estimated useful lives. In general, the declining-balance method is used to depreciate plant and equipment in the United States; the straight-line method is generally used to depreciate international plant and equipment and to amortize finance lease right-of-use assets. Gains or losses are not recognized for normal retirements of properties, plant and equipment subject to composite group amortization or depreciation. Gains or losses from abnormal retirements are recorded as expenses, and from sales as “Other income.” Expenditures for maintenance (including those for planned major maintenance projects), repairs and minor renewals to maintain facilities in operating condition are generally expensed as incurred. Major replacements and renewals are capitalized.
Leases	Leases Leases are classified as operating or finance leases. Both operating and finance leases recognize lease liabilities and associated right-of-use assets. The company has elected the short-term lease exception and therefore only recognizes right-of-use assets and lease liabilities for leases with a term greater than one year. The company has elected the practical expedient to not separate non-lease components from lease components for most asset classes except for certain asset classes that have significant non-lease (i.e., service) components. Where leases are used in joint ventures, the company recognizes 100 percent of the right-of-use assets and lease liabilities when the company is the sole signatory for the lease (in most cases, where the company is the operator of a joint venture). Lease costs reflect only the costs associated with the operator’s working interest share. The lease term includes the committed lease term identified in the contract, taking into account renewal and termination options that management is
Goodwill	Goodwill Goodwill resulting from a business combination is not subject to amortization. The company tests such goodwill at the reporting unit level for impairment annually at December 31, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying amount.
Environmental Expenditures	Environmental Expenditures Environmental expenditures that relate to ongoing operations or to conditions caused by past operations are expensed. Expenditures that create future benefits or contribute to future revenue generation are capitalized. Liabilities related to future remediation costs are recorded when environmental assessments or cleanups or both are probable and the costs can be reasonably estimated. For crude oil, natural gas and mineral-producing properties, a liability for an ARO is made in accordance with accounting standards for asset retirement and environmental obligations. Refer to Note 25 Asset Retirement Obligations for a discussion of the company’s AROs.
Currency Translation	Currency Translation The U.S. dollar is the functional currency for substantially all of the company’s consolidated operations and those of its equity affiliates. For those operations, all gains and losses from currency remeasurement are included in current period income. The cumulative translation effects for those few entities, both consolidated and affiliated, using functional currencies other than the U.S. dollar are included in “Currency translation adjustment” on the Consolidated Statement of Equity.
Revenue Recognition	Revenue Recognition The company accounts for each delivery order of crude oil, natural gas, petroleum and chemical products as a separate performance obligation. Revenue is recognized when the performance obligation is satisfied, which typically occurs at the point in time when control of the product transfers to the customer. Payment is generally due within 30 days of delivery. The company accounts for delivery transportation as a fulfillment cost, not a separate performance obligation, and recognizes these costs as an operating expense in the period when revenue for the related commodity is recognized. Revenue is measured as the amount the company expects to receive in exchange for transferring commodities to the customer. The company’s commodity sales are typically based on prevailing market-based prices and may include discounts and allowances. Until market prices become known under terms of the company’s contracts, the transaction price included in revenue is based on the company’s estimate of the most likely outcome. Discounts and allowances are estimated using a combination of historical and recent data trends. When deliveries contain multiple products, an observable standalone selling price is generally used to measure revenue for each product. The company includes estimates in the transaction price only to the extent that a significant reversal of revenue is not probable in subsequent periods. Revenue from contracts with customers is presented in “Sales and other operating revenue” along with some activity that is accounted for outside the scope of Accounting Standard Codification (ASC) 606, which is not material to this line, on the Consolidated Statement of Income. Purchases and sales of inventory with the same counterparty that are entered into in contemplation of one another (including buy/sell arrangements) are combined and recorded on a net basis and reported in “Purchased crude oil and products” on the Consolidated Statement of Income. Refer to Note 14 Operating Segments and Geographic Data for additional information on the company’s segmentation of revenue. Receivables related to revenue from contracts with customers are included in “Accounts and notes receivable, net” on the Consolidated Balance Sheet, net of the allowance for doubtful accounts. The net balance of these receivables was $12,877 and $7,631 at December 31, 2021 and December 31, 2020, respectively. Other items included in “Accounts and notes receivable, net” represent amounts due from partners for their share of joint venture operating and project costs and amounts due from others, primarily related to derivatives, leases, buy/sell arrangements and product exchanges, which are accounted for outside the scope of ASC 606 . Contract assets and related costs are reflected in “Prepaid expenses and other current assets” and contract liabilities are reflected in “Accrued liabilities” and “Deferred credits and other noncurrent obligations” on the Consolidated Balance Sheet. Amounts for these items are not material to the company’s financial position.
Stock Options and Other Share-Based Compensation	Stock Options and Other Share-Based Compensation The company issues stock options and other share-based compensation to certain employees. For equity awards, such as stock options, total compensation cost is based on the grant date fair value, and for liability awards, such as stock appreciation rights, total compensation cost is based on the settlement value. The company recognizes stock-based compensation expense for all awards over the service period required to earn the award, which is the shorter of the vesting period or the time period in which an employee becomes eligible to retain the award at retirement. The company’s Long-Term Incentive Plan (LTIP) awards include stock options and stock appreciation rights, which have graded vesting provisions by which one-third of each award vests on each of the first, second and third anniversaries of the date of grant. In addition, performance shares granted under the company’s LTIP will vest at the end of the three
Segment Reporting	Although each subsidiary of Chevron is responsible for its own affairs, Chevron Corporation manages its investments in these subsidiaries and their affiliates. The investments are grouped into two business segments, Upstream and Downstream, representing the company’s “reportable segments” and “operating segments.” Upstream operations consist primarily of exploring for, developing, producing and transporting crude oil and natural gas; liquefaction, transportation and regasification associated with liquefied natural gas (LNG); transporting crude oil by major international oil export pipelines; processing, transporting, storage and marketing of natural gas; and a gas-to-liquids plant. Downstream operations consist primarily of refining of crude oil into petroleum products; marketing of crude oil, refined products, and lubricants; manufacturing and marketing of renewable fuels; transporting of crude oil and refined products by pipeline, marine vessel, motor equipment and rail car; and manufacturing and marketing of commodity petrochemicals, plastics for industrial uses, and fuel and lubricant additives. All Other activities of the company include worldwide cash management and debt financing activities, corporate administrative functions, insurance operations, real estate activities, and technology activities. The company’s segments are managed by “segment managers” who report to the “chief operating decision maker” (CODM). The segments represent components of the company that engage in activities (a) from which revenues are earned and expenses are incurred; (b) whose operating results are regularly reviewed by the CODM, which makes decisions about resources to be allocated to the segments and assesses their performance; and (c) for which discrete financial information is available. The company’s primary country of operation is the United States of America, its country of domicile. Other components of the company’s operations are reported as “International” (outside the United States). Segment Earnings
Uncertain Income Tax Positions	Uncertain Income Tax Positions The company recognizes a tax benefit in the financial statements for an uncertain tax position only if management’s assessment is that the position is “more likely than not” (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term “tax position” in the accounting standards for income taxes refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.
Accounting for Suspended Exploratory Wells	Accounting for Suspended Exploratory Wells The company continues to capitalize exploratory well costs after the completion of drilling when the well has found a sufficient quantity of reserves to justify completion as a producing well, and the business unit is making sufficient progress assessing the reserves and the economic and operating viability of the project. If either condition is not met or if the company obtains information that raises substantial doubt about the economic or operational viability of the project, the exploratory well would be assumed to be impaired, and its costs, net of any salvage value, would be charged to expense.
