Chevron Corporation is an American multinational energy corporation specialising principally in oil and gas. The second-largest direct descendant of Standard Oil, and originally the Standard Oil Company of California, it operates in more than 180 countries.

Chevron is vertically integrated across hydrocarbon exploration, production, refining, marketing and transport, chemicals manufacture and power generation. It manufactures and sells fuels, lubricants, additives and petrochemicals, principally in western North America, the United States Gulf Coast, Southeast Asia, South Korea and Australia.

It ranked tenth on the Fortune 500 in 2023 and is the second-largest American oil company by revenue after ExxonMobil, another Standard Oil descendant. It is the last remaining oil and gas component of the Dow Jones Industrial Average, ExxonMobil having left the index in 2020.

The company has been the subject of extensive controversy over its environmental record, most prominently the contamination of the Lago Agrio oil field in Ecuador, a liability inherited with Texaco in 2001, and the subsequent litigation against the lawyer Steven Donziger. In 2024 Chevron was responsible for 512 million tonnes of carbon dioxide emissions, approximately 1.33 per cent of the global total.

History

Predecessors

Chevron's earliest predecessor, Star Oil, discovered oil at Pico Canyon in the Santa Susana Mountains north of Los Angeles in 1876. The well, producing 25 barrels a day, marked the discovery of the Newhall Field and has been described by the geophysicist Marius Vassiliou as the beginning of the modern oil industry in California. The energy analyst Antonia Juhasz has noted that while Star Oil's founders were influential in establishing the Californian industry, the Union Mattole Company had discovered oil in the state eleven years earlier.

In September 1879 Charles N. Felton, Lloyd Tevis, George Loomis and others formed the Pacific Coast Oil Company, which acquired Star Oil's assets with one million dollars of funding. Pacific Coast became the largest oil interest in California, and in 1900 John D. Rockefeller's Standard Oil acquired it for 761,000 dollars. In 1906 Pacific Coast absorbed the operations and assets of the Standard Oil Company of Iowa and renamed itself the Standard Oil Company (California).

Texaco

Chevron worked closely with Texaco for a century before acquiring it outright in 2001. Originally the Texas Fuel Company and later the Texas Company, Texaco was founded at Beaumont, Texas, as an oil equipment vendor by Joseph Cullinan, known as Buckskin Joe for his abrasive manner.

In 1936 Texaco formed a joint venture with California Standard named Caltex to drill and produce oil in Saudi Arabia. According to Juhasz, the two companies were often described as the terrible twins for the severity of their business practices.

Standard Oil breakup and the Chevron name

In 1911 the federal government broke Standard Oil into several companies under the Sherman Antitrust Act. One of the pieces, Standard Oil Co. (California), became Chevron, and joined the group of companies later known as the Seven Sisters that dominated the world oil industry through the middle of the twentieth century. The company adopted the name Standard Oil Co. of California in 1926.

Under the terms of the breakup, Standard of California could use the Standard name only within its original territory of the Pacific coast states plus Nevada and Arizona, and had to trade under another name elsewhere. Chevron today owns the Standard Oil trademark in sixteen western and south-eastern states. Because American trademark law operates on a use-it-or-lose-it basis, the company maintains one Standard-branded Chevron station in each state of that territory. Its position in Kentucky became unclear after it withdrew from retail sales there in July 2010.

The Chevron name came into use for some retail products in the 1930s, and the name Calso was used between 1946 and 1955 in states outside the west coast territory. Standard Oil Company of California ranked 75th among American corporations by the value of Second World War military production contracts.

Saudi Arabia and Aramco

In 1933 Saudi Arabia granted California Standard a concession to search for oil, and the company made its discovery in 1938. In 1948 it found Ghawar, the largest conventional oil field ever discovered.

California Standard's subsidiary, the California-Arabian Standard Oil Company, grew into the Arabian American Oil Company, ARAMCO, in 1944. The Saudi government began buying into ARAMCO in 1973, owned it entirely by 1980, and renamed it Saudi Arabian Oil Company, Saudi Aramco, in 1988.

The concession is among the most consequential commercial arrangements of the twentieth century. It placed an American company at the centre of the largest hydrocarbon reserves on earth, shaped the relationship between the United States and Saudi Arabia, and its eventual nationalisation established the pattern by which producing states took control of their own resources.

Merger with Gulf Oil, 1984

Standard Oil of California and Gulf Oil merged in 1984 in what was at the time the largest merger in history. To comply with antitrust law, California Standard divested many Gulf operating subsidiaries and sold Gulf stations in the eastern United States together with a Philadelphia refinery since closed.

Among the assets sold were Gulf's retail outlets in its home market of Pittsburgh, where Chevron has no retail presence, though it retained a regional headquarters there between 2010 and 2021, partly for drilling in the Marcellus Shale. Chevron sold the Gulf Oil trademarks for the entire United States to Cumberland Farms in 2010, that company having licensed the mark in the north-east since 1986.

In the same year Standard Oil of California changed its legal name to Chevron Corporation, having used the Chevron retail brand for decades.

Dynegy

In 1996 Chevron transferred its natural gas gathering, operating and marketing business to NGC Corporation, later Dynegy, in exchange for a holding of roughly 25 per cent. When Illinova Corporation became a wholly owned subsidiary of Dynegy in a merger completed on 1 February 2000, Chevron's stake rose to 28 per cent. It sold the holding in May 2007 for approximately 985 million dollars, realising a gain of 680 million dollars.

Texaco and Unocal, 2000 to 2005

Chevron announced the 45 billion dollar acquisition of Texaco on 15 October 2000. The transaction created the second-largest oil company in the United States and the fourth-largest publicly traded oil company in the world, with a combined market value of approximately 95 billion dollars. It completed on 9 October 2001, and the company traded as ChevronTexaco between 2001 and 2005 before reverting to Chevron, retaining Texaco as a retail brand.

In 2005 Chevron bought Unocal Corporation for 18.4 billion dollars, increasing its petroleum and natural gas reserves by about 15 per cent. Because of Unocal's substantial South East Asian geothermal operations, the purchase made Chevron a large producer of geothermal energy. The deal excluded Unocal's former retail business, including the Union 76 trademark, which had been sold to Tosco Corporation in 1997 and is now owned by Phillips 66.

The Unocal acquisition was politically contested. The Chinese state-owned CNOOC made a higher competing bid, which was withdrawn following opposition in the United States Congress on national security grounds, an early instance of energy assets becoming a subject of strategic rather than purely commercial competition.

Oil shale and disposals, 2006 to 2019

Chevron and the Los Alamos National Laboratory began cooperating in 2006 to improve hydrocarbon recovery from oil shale through a process named Chevron CRUSH, and the Department of the Interior issued a research and demonstration lease for a project in Colorado's Piceance Basin. Chevron notified the Bureau of Land Management in February 2012 that it intended to divest the lease.

In 2008 a Chevron subsidiary sold its equity distributor business in the United Kingdom to GB Oils for 21.9 million pounds.

From 2010 Chevron reduced its retail footprint and expanded in domestic natural gas. In July 2010 it ended retail operations in the mid-Atlantic, removing the Chevron and Texaco names from 1,100 stations. In 2011 it acquired the Pennsylvania company Atlas Energy for 3.2 billion dollars in cash plus 1.1 billion dollars of assumed debt, and three months later bought drilling and development rights to a further 228,000 acres in the Marcellus Shale from Chief Oil and Gas and Tug Hill. In September 2013 Total and a joint venture partner agreed to buy Chevron's retail distribution business in Pakistan.

In October 2014 Chevron sold a 30 per cent holding in its Canadian oil shale assets to the Kuwait Oil Company for 1.5 billion dollars. It sold its North Sea operations to Ithaca Energy for two billion dollars in May 2019.

In April 2019 Chevron announced an intention to acquire Anadarko Petroleum for 33 billion dollars, and withdrew when Occidental Petroleum outbid it, collecting a one billion dollar break fee. It acquired Noble Energy for five billion dollars in July 2020, gaining substantial positions in the Eastern Mediterranean including the Leviathan and Tamar gas fields offshore Israel.

Pandemic and consolidation, 2020 onward

Chevron reduced its workforce by 10 to 15 per cent during 2020 in response to the pandemic and the oil price war between Russia and Saudi Arabia. During the early stages of the pandemic it discussed a merger with ExxonMobil, which would have been among the largest corporate combinations in history and would have created the second-largest oil company in the world behind Saudi Aramco. The talks did not proceed.

The company later required some employees, including expatriate staff, those working overseas and workers on United States-flagged vessels, to be vaccinated against COVID-19.

In the 2020s Chevron concentrated on the Americas, withdrew gradually from parts of Africa and Southeast Asia, and invested in lower-carbon businesses. In February 2020 it joined Marubeni and WAVE Equity Partners in investing in Carbon Clean Solutions, which supplies portable carbon capture technology. In 2022 it agreed to acquire Renewable Energy Group, a biodiesel producer based in Ames, Iowa, completing on 13 June. In November 2022 it bought the compressed natural gas company Beyond6 and its 55 stations from Mercuria.

It acquired Hess Corporation in 2024 after a protracted arbitration with ExxonMobil over rights of first refusal relating to the Stabroek block offshore Guyana, one of the most significant oil discoveries of the century, which Chevron won in 2025.

In 2025 the company relocated its corporate headquarters from San Ramon, California, where it had been based for decades, to Houston, citing proximity to the industry's centre of gravity and, implicitly, the regulatory and tax environment in Texas.

Operations

Chevron reports in two principal segments, upstream and downstream, supported by a chemicals business held in joint venture and by a growing new energies division.

Upstream

Upstream covers exploration, development and production of crude oil and natural gas, together with liquefied natural gas processing, transport and marketing, and carbon capture and storage. It generates the large majority of earnings.

In 2018 the company produced an average of 791,000 barrels of net oil equivalent a day in the United States alone. Production has since been reshaped by the Permian Basin, Guyana and the Eastern Mediterranean.

The Permian Basin in west Texas and New Mexico has become the company's most important asset. Chevron holds a large acreage position, much of it on favourable legacy terms inherited from land grants made to the Pacific Railroad in the nineteenth century and acquired through predecessors, meaning that a substantial part of the acreage carries no royalty obligation. The company has applied a factory approach to drilling, emphasising the pace and cost of repeated wells rather than individual well performance, and has treated the basin as a source of production that can be dialled up or down quickly in response to price.

Kazakhstan is the site of Tengizchevroil, a joint venture operating the Tengiz field, one of the largest and deepest in the world and among the most technically difficult because of high pressure and hydrogen sulphide content. The associated Future Growth Project, a multi-year expansion costing well above its original budget, increased capacity substantially. Chevron also holds an interest in the Karachaganak field and in the Caspian Pipeline Consortium, the export route that carries Kazakh crude across Russian territory to the Black Sea, a dependency that has become a significant political vulnerability.

Australia hosts the Gorgon and Wheatstone liquefied natural gas projects, among the largest resource developments ever undertaken by a private company. Gorgon, on Barrow Island, included the world's largest carbon dioxide injection scheme as a condition of its environmental approval.

Guyana became a major position through the acquisition of Hess, which holds 30 per cent of the Stabroek block operated by ExxonMobil, containing discoveries exceeding eleven billion barrels of recoverable oil equivalent, with very low production costs and rapid development timelines.

The Eastern Mediterranean came with Noble Energy: the Leviathan and Tamar gas fields offshore Israel, which supply the Israeli domestic market and export to Egypt and Jordan, and which sit within a contested maritime and political environment.

Other significant upstream positions include the Gulf of Mexico deepwater, Nigeria, Angola, Argentina's Vaca Muerta shale, Thailand and, subject to sanctions policy, Venezuela.

Downstream

Downstream covers refining, marketing, transport and lubricants. Chevron operates refineries including El Segundo and Richmond in California, Pascagoula in Mississippi and Salt Lake City in Utah, together with interests in refineries overseas.

The Pascagoula refinery is among the largest in the United States and supplies the Gulf Coast and export markets. The Californian refineries serve a state whose fuel specification is unique and whose regulatory environment the company has repeatedly described as hostile, a tension that culminated in the 2025 headquarters move to Houston and in announcements by Californian refiners, including Chevron's competitors, of closures.

Retail operates under the Chevron and Texaco brands in the Americas and the Caltex brand across Asia-Pacific, Africa and the Middle East. Chevron sells lubricants under the Havoline, Delo and Ursa names.

Chemicals

Chevron Phillips Chemical, owned equally with Phillips 66, manufactures olefins, polyolefins, aromatics and speciality chemicals, with major plants on the United States Gulf Coast and in the Middle East. It has invested in petrochemical capacity on the reasoning that demand for plastics and chemical feedstocks will persist longer than demand for transport fuels.

Chevron Oronite manufactures fuel and lubricant additives.

New energies

Chevron established a New Energies division in 2021 focused on hydrogen, carbon capture and storage, renewable fuels and offsets, alongside continued venture investment.

Renewable Energy Group, acquired in 2022, makes it a substantial producer of biodiesel and renewable diesel. In September 2023 the company took a majority stake in the Advanced Clean Energy Storage project in Utah, intended to be the largest hydrogen storage facility in the world, using salt caverns to store hydrogen produced from renewable electricity.

The company has invested in fusion research through stakes in Zap Energy and TAE Technologies, and in carbon capture through Carbon Clean Solutions and the Bayou Bend offshore sequestration hub on the Gulf Coast.

The strategy differs from that adopted by the European majors. Where BP and Shell announced substantial pivots toward electricity generation and renewables and subsequently retreated from those targets, Chevron and ExxonMobil concentrated on lowering the carbon intensity of existing operations and on technologies adjacent to their engineering competence, principally carbon capture, hydrogen and biofuels, arguing that they have no comparative advantage in building wind farms. Investors initially penalised the American approach and subsequently rewarded it as the European companies scaled back.

Venezuela

Chevron is the only major American oil company to have maintained a continuous presence in Venezuela through the nationalisations of the Chávez era and the sanctions that followed.

Restrictions imposed over corruption and human rights violations under Nicolás Maduro were relaxed by the Biden administration in November 2022, allowing Chevron to resume pumping, subject to conditions prohibiting sales to Russian or Iranian-affiliated entities and preventing direct profits reaching the state company PDVSA, with revenue instead applied to outstanding debts owed to Chevron.

On 29 November 2022 the Venezuelan petroleum minister Tareck El Aissami met the president of Chevron, Javier La Rosa, in Caracas, and the governing party stated its commitment to the development of oil production following the easing of sanctions. El Aissami resigned in March 2023 amid corruption allegations; he was a long-standing Maduro ally subject to a ten million dollar United States reward over alleged facilitation of drug trafficking, and had played a central role in evading economic sanctions.

Chevron's principal Venezuelan joint ventures are Petroboscán in the west and Petropiar in the eastern Orinoco Belt, with combined capacity near 180,000 barrels a day. Production at Petroboscán has at points been nil, while Petropiar has recorded close to 50,000 barrels a day.

The licence has been repeatedly narrowed, suspended and restored as United States policy has shifted, making the position one of the clearest illustrations of how far the company's operations depend on foreign policy decisions outside its control.

Financial performance

Chevron's results track the oil price closely. The company recorded losses in 2020 as demand collapsed during the pandemic, then reported record figures in 2022 following the Russian invasion of Ukraine: revenue of 246.3 billion dollars and profit of 36.5 billion dollars, both company records.

Days before publishing those results it raised its dividend and announced a 75 billion dollar share repurchase programme, drawing sharp criticism from the Biden administration and from commentators who argued that windfall profits arising from a war were being returned to shareholders rather than invested in production or passed to consumers. The company's response was that production decisions are governed by long-term economics rather than by short-term prices, and that returning capital is the appropriate use of cash the business cannot deploy at adequate returns.

Chevron has increased its dividend annually for more than three decades, a record maintained through several severe downturns and central to its shareholder base, which is weighted toward income investors. Capital discipline, meaning restraint in spending even when prices are high, has been the stated strategy since the industry's heavy losses in the 2014 to 2016 downturn.

Chevron deference

Chevron gave its name to one of the most consequential doctrines in American administrative law. In Chevron U.S.A., Inc. v. Natural Resources Defense Council (1984), the Supreme Court considered an Environmental Protection Agency interpretation of the Clean Air Act permitting a plant-wide definition of a pollution source, known as the bubble concept, which Chevron favoured and environmental groups opposed.

The court upheld the agency, and in doing so established a two-step framework: where a statute is ambiguous, courts should defer to a reasonable interpretation by the agency charged with administering it. Chevron deference became among the most cited decisions in American law, and for four decades it underpinned the regulatory authority of federal agencies across environmental, labour, health, financial and communications policy.

The Supreme Court overruled it in Loper Bright Enterprises v. Raimondo in 2024, holding that courts must exercise independent judgement in interpreting statutes. The decision transferred substantial interpretive power from agencies to the judiciary and is expected to make environmental and energy regulation considerably harder to sustain against challenge, an outcome that benefits the industry whose litigation created the doctrine in the first place.

Controversies

Ecuador and the Lago Agrio litigation

The most protracted controversy in Chevron's history concerns contamination in the Ecuadorian Amazon, inherited with Texaco in 2001.

Texaco operated in the Oriente region from 1964 to 1992 in consortium with the state company Petroecuador. Plaintiffs alleged that the operation deliberately discharged billions of gallons of produced water into unlined pits and waterways, and that the resulting contamination caused illness and destroyed the livelihoods of Indigenous communities including the Cofán, Siona, Secoya, Kichwa and Waorani.

Texaco conducted a remediation programme in the 1990s and obtained a release from the Ecuadorian government in 1998 covering its share of the liability. Chevron has consistently argued that this release extinguished its obligations, that Petroecuador operated the fields for two decades afterwards and is responsible for subsequent contamination, and that it never operated in the country in its own name.

Litigation begun in New York in 1993 was moved at Chevron's request to Ecuador, where in 2011 a court at Lago Agrio awarded 18 billion dollars, later reduced to 9.5 billion dollars. Chevron refused to pay, having by then no assets in Ecuador, and the plaintiffs sought enforcement in Canada, Brazil and Argentina.

Chevron then brought civil racketeering proceedings in New York against the plaintiffs' lawyer, Steven Donziger. In 2014 Judge Lewis Kaplan found that the Ecuadorian judgment had been obtained by fraud, that Donziger had ghostwritten a court-appointed expert's report and had promised a bribe to the judge, and declared the judgment unenforceable in the United States. The central testimony came from a former Ecuadorian judge, Alberto Guerra, who later admitted under oath in a separate arbitration that parts of his account had been untrue, and who had received payments and relocation from Chevron.

Donziger was subsequently held in contempt for refusing to surrender his electronic devices, prosecuted by a private law firm appointed by Kaplan after federal prosecutors declined the case, and placed under house arrest for more than two years before serving a further sentence. A United Nations working group found his detention arbitrary and in violation of international law. Supporters, including numerous Nobel laureates and human rights organisations, described the proceedings as the criminalisation of advocacy; Chevron maintains that the findings of fraud were made by a federal court after a full trial and have been upheld on appeal.

An international arbitration tribunal under the United States and Ecuador bilateral investment treaty subsequently ruled in Chevron's favour, finding that Ecuador had breached the 1998 settlement and ordering it to nullify the judgment.

The contamination itself has never been comprehensively remediated, and the communities affected have received nothing.

Richmond refinery

The Richmond refinery in California, one of the company's oldest, sits adjacent to a densely populated and predominantly working-class community. On 6 August 2012 a corroded pipe released hydrocarbon vapour that ignited, producing a fire and a plume that sent approximately 15,000 local residents to hospital seeking treatment for respiratory complaints.

The United States Chemical Safety Board found that Chevron had repeatedly declined recommendations from its own inspectors to replace the corroded line. The company pleaded no contest to six charges and paid two million dollars in fines and restitution, and settled with the city of Richmond for five million dollars.

Chevron has spent heavily on Richmond municipal politics, funding slates of candidates in local elections, most visibly in 2014 when it spent approximately three million dollars in a city of about 100,000 people and its preferred candidates were nonetheless defeated. In 2024 the company agreed to pay the city 550 million dollars over ten years in exchange for the withdrawal of a proposed ballot measure taxing refinery throughput.

Nigeria

Chevron's operations in the Niger Delta have generated repeated conflict with host communities over environmental damage, gas flaring and the distribution of revenue.

In May 1998 protesters occupied the Parabe offshore platform. Chevron transported Nigerian security forces to the platform by company helicopter, and two protesters were shot dead. Survivors sued under the Alien Tort Statute in Bowoto v. Chevron; a San Francisco jury found for Chevron in 2008, accepting that the company had called for assistance against what it regarded as a hostage situation.

Gas flaring in the Delta, long practised by all operators, has been a persistent source of criticism for its contribution to emissions, air quality and the waste of a resource that could have been captured.

Myanmar

Chevron held an interest in the Yadana gas pipeline, inherited from Unocal. Unocal had been sued in Doe v. Unocal over allegations that the Burmese military used forced labour, and committed killings and rape, in securing the pipeline route; the case settled in 2005 shortly before Chevron completed its acquisition.

In January 2022 Chevron announced that it would end all operations in Myanmar, citing human rights abuses and the deterioration of the rule of law following the 2021 coup, while stating a commitment to an orderly exit that would continue to supply energy to the region. Campaigners had argued for a faster withdrawal and for the suspension of payments to the military government in the interim.

Climate change

Chevron is among the small group of companies identified in the Carbon Majors research as responsible for a substantial share of cumulative industrial greenhouse gas emissions. In 2024 its emissions totalled 512 million tonnes of carbon dioxide, about 1.33 per cent of the global figure.

It is a defendant in numerous American lawsuits brought by states and municipalities seeking damages for climate-related harms on theories of public nuisance, failure to warn and deceptive marketing, and in proceedings elsewhere. The suits rest in substantial part on documents indicating that the industry understood the climate consequences of its products decades before it acknowledged them publicly, and that it funded organisations that disputed the science.

In 2024 the Federal Trade Commission was asked to examine Chevron's advertising on the basis that it overstated the significance of its lower-carbon investments relative to its overall capital spending, a complaint the company rejected.

Chevron's stated position is that it supports the Paris objectives, that it will reduce the carbon intensity of its production, and that hydrocarbons will remain necessary for decades, so that the responsible course is to supply them with lower emissions rather than to withdraw and cede supply to producers with weaker standards.

Clean Air Act violations

In March 2022 Chevron Phillips Chemical agreed to pay 118 million dollars over violations of the Clean Air Act at three Texas plants. The Department of Justice and Environmental Protection Agency found that the company had failed to operate flares properly, causing excess air pollution, and it agreed to install additional pollution control equipment.

Kazakhstan

Chevron reduced production at the Tengiz field in January 2022 during nationwide protests triggered by fuel price increases, which developed into the most serious unrest in Kazakhstan's independent history. Contract workers at the field have struck repeatedly over pay differentials between local and expatriate staff, and the concentration of the country's economy around a field operated by foreign companies has been a recurring political issue.

Political spending

Chevron is among the largest corporate spenders on lobbying in the United States and a significant donor to political committees. Its expenditure at municipal level in refinery communities, particularly Richmond, has attracted particular criticism for the disproportion between corporate resources and the size of the electorates concerned.

Disposals and legacy liabilities

Chevron's withdrawals from Africa and Southeast Asia have drawn criticism from campaigners who argue that selling ageing assets to smaller operators transfers decommissioning and remediation obligations to companies less able to meet them, leaving the liability with host states. The same argument has been made about the industry's disposals in the Niger Delta and the Gulf of Mexico.

Corporate affairs

Leadership

Mike Wirth has been chairman and chief executive since 2018, having joined the company in 1982 as a design engineer and risen through the refining and marketing businesses. His tenure has been defined by capital discipline, the Permian and Guyana positions, the Hess acquisition and arbitration, the relocation to Houston, and a lower-carbon strategy deliberately narrower than that of the European majors.

His predecessors include John Watson, chief executive from 2010 to 2018, who oversaw the Gorgon and Wheatstone projects and the industry's heavy losses in the downturn after 2014; David O'Reilly, from 2000 to 2009, who completed the Texaco and Unocal acquisitions; and Kenneth Derr, from 1989 to 1999, who restructured the company after the Gulf merger.

Governance

Chevron's board is drawn largely from industry, finance, academia and public service. Shareholder activity has been unusually persistent, with annual resolutions on emissions targets covering the use of sold products, on climate lobbying, on human rights due diligence and on the reporting of decommissioning liabilities. Several have attracted substantial minority support; a 2021 resolution asking the company to reduce emissions from the use of its products passed against the board's recommendation, an outcome that at the time was read as a significant shift in institutional investor sentiment and that has since partially reversed.

The activist investor Engine No. 1, which won board seats at ExxonMobil in 2021, drew attention to governance across the sector on the argument that boards lacked directors capable of assessing the risks of the energy transition.

Headquarters

Chevron was headquartered in San Francisco for most of its history and moved to a campus at San Ramon in the East Bay in 2002. In August 2024 it announced the relocation of its corporate headquarters to Houston, completing the move in 2025 and ending nearly 150 years of Californian domicile.

The company cited the concentration of the industry, its customers and its partners in Houston. Commentators also noted the contrast between California's regulatory regime, including its low carbon fuel standard, refinery rules and the state's own litigation against oil companies over climate damages, and the environment in Texas. Chevron retains substantial Californian operations, including the El Segundo and Richmond refineries and the San Ramon site.

Employment

Chevron employs approximately 45,000 people worldwide, a figure reduced substantially from earlier decades through disposals, outsourcing and successive restructurings, including the 10 to 15 per cent reduction announced during the pandemic and further cuts announced in 2025 as part of a programme to reduce structural costs.

The workforce is concentrated in engineering, geoscience, operations and trading. The company runs extensive graduate recruitment and has historically emphasised long careers and internal promotion, a pattern visible in the fact that its recent chief executives have each spent their entire working lives with the company.

Research and technology

Chevron Technical Center conducts research in reservoir characterisation, seismic imaging, enhanced oil recovery, drilling and completion, refining catalysis and, more recently, carbon capture and hydrogen.

The company has been a significant developer of deepwater production technology, subsea processing and high-pressure high-temperature drilling, capabilities required by the Gulf of Mexico and by fields such as Tengiz. Its interest in fusion, through Zap Energy and TAE Technologies, and in geothermal, inherited through Unocal, reflects a view that its engineering capability in subsurface and high-energy systems may transfer to other forms of generation.

Chevron Technology Ventures, established in 1999, is among the longer-established corporate venture arms in the sector.

Brand

The Chevron name and the chevron device, a pair of angled stripes in red and blue, have been used in retail since the 1930s. The company maintains three retail brands: Chevron in the Americas, Texaco in the Americas, Europe and Africa, and Caltex in Asia-Pacific, the Middle East and southern Africa.

Its advertising has for decades emphasised community, employees and technology rather than products, a strategy typical of an industry whose brand risk lies less in competitive positioning than in public licence to operate. The long-running Human Energy campaign is an example.

Chevron has sponsored Houston's professional sports and cultural institutions, and the Chevron Houston Marathon has carried the company's name since 2009. Its sponsorship of the golf tournament formerly known as the Dinah Shore, now the Chevron Championship, and its arts and education giving in refinery communities form part of the same approach.

Competition

Chevron's peers among the international majors are ExxonMobil, Shell, BP and TotalEnergies, with ConocoPhillips competing in upstream and the American independents including Occidental, EOG and Devon competing in shale.

The far larger producers are national oil companies, principally Saudi Aramco, the National Iranian Oil Company, Rosneft, Petrobras and CNPC, which control the majority of the world's reserves. The majors' position rests not on reserves, to which their access is limited, but on the technical and project management capability required to develop difficult resources, and on their integration across the chain.

The competitive question specific to Chevron is its concentration. It has a smaller and more focused portfolio than ExxonMobil or Shell, weighted toward the Permian, Kazakhstan, Australia and now Guyana. That concentration produces higher returns when those assets perform and greater exposure when any one of them is disrupted, as the dependence of Kazakh exports on a pipeline crossing Russia demonstrates.

Legacy of Standard Oil

Chevron is one of two large survivors of the 1911 dissolution of Standard Oil, alongside ExxonMobil, which was formed from the merger of the two largest fragments, Standard Oil of New Jersey and Standard Oil of New York.

The breakup produced 34 companies, several of which recombined over the following century: Chevron absorbed Standard Oil of Kentucky, Gulf and Texaco; Exxon and Mobil merged in 1999; and Amoco, formerly Standard Oil of Indiana, was acquired by BP. Within ninety years, a substantial part of what antitrust had separated had been reassembled, a pattern frequently cited in debate about the durability of structural remedies in competition law.

The Standard trademark persists in fragmentary form, with Chevron holding rights in sixteen states and maintaining a single Standard-branded station in each to preserve them.

Products

Fuels

Chevron markets petrol and diesel through approximately 8,000 Chevron and Texaco stations in the United States and several thousand Caltex sites internationally. Its fuels carry the Techron additive, introduced in 1995, a polyether amine detergent intended to reduce deposits on injectors and intake valves, and marketed heavily as a point of differentiation in a category where the base product is fungible.

The company also supplies aviation fuel, marine fuel and fuel oil to commercial and government customers, and operates a substantial trading business in crude and refined products, which both optimises the flow of its own barrels and takes positions in its own right.

Lubricants

Chevron is among the largest lubricant manufacturers in the world, selling Havoline for passenger vehicles, Delo for heavy duty and commercial fleets, Ursa for industrial and marine applications, and Rando and Regal for hydraulic and turbine use. Lubricants earn margins substantially higher than fuels and are less exposed to the decline in internal combustion transport, since industrial, marine and heavy equipment demand persists.

Base oils and additives

Chevron produces base oils, the refined stock from which lubricants are blended, and through Chevron Oronite manufactures the additive packages that determine a lubricant's performance. Oronite is one of a very small number of significant additive suppliers worldwide, and it sells to competitors as well as to Chevron's own blending operations.

Shipping

Chevron Shipping Company operates and charters a fleet of crude carriers, product tankers and liquefied natural gas vessels, moving the company's production to its refineries and markets. The fleet has been used to trial lower-carbon marine fuels and efficiency measures, and the company has been among the participants in industry work on methane slip from gas-fuelled engines.

Health, safety and environment

Chevron reports process safety and personal safety metrics annually, and operates a management system that governs design, maintenance and incident investigation across its facilities.

Its record nonetheless includes serious incidents beyond Richmond. These have involved refinery fires, offshore incidents, pipeline releases and, historically, contamination at legacy sites inherited through acquisition, including sites in California where operations predate modern environmental regulation by many decades.

The company's remediation obligations extend to fields and facilities acquired with Texaco, Gulf, Unocal and Noble, several of which carry liabilities arising from practices that were lawful when undertaken. The scale of eventual decommissioning costs across the industry, particularly for offshore infrastructure, is a recognised uncertainty in the sector's accounts.

The energy transition

Chevron's stated position is that global energy demand will continue to rise, that hydrocarbons will remain a substantial part of supply for decades, and that the company's contribution is to produce them at lower carbon intensity while investing in technologies where its engineering capability applies.

The strategic argument for this approach is that an oil company has no particular advantage in building wind farms or solar parks, which are financed and operated more cheaply by utilities and infrastructure funds, and that shareholders who want exposure to renewables can buy it directly. The counter-argument is that the approach amounts to managing decline while relying on offsets and on capture technologies that remain unproven at scale, and that it leaves the company exposed if demand falls faster than it assumes.

The divergence between the American and European majors on this question is among the clearest strategic splits in any global industry. BP and Shell announced substantial reallocations of capital toward electricity and renewables around 2020, were rewarded by some investors and punished by others, and both subsequently reduced those commitments and returned emphasis to oil and gas. Chevron and ExxonMobil did not move, and their relative share price performance through that period has been widely cited by each side of the argument.

What is not disputed is the arithmetic of the company's spending. The large majority of Chevron's capital budget continues to be directed at oil and gas, with lower-carbon investment measured in low single-digit billions against total capital expenditure several times larger, a ratio the company presents as proportionate and its critics present as evidence that the transition commitments are peripheral.

Human rights

Chevron publishes a human rights policy aligned to the United Nations Guiding Principles on Business and Human Rights, covering security arrangements, community engagement, resettlement and grievance mechanisms, and it participates in the Voluntary Principles on Security and Human Rights.

Its operations nonetheless take place in jurisdictions where those commitments are difficult to honour, including Nigeria, Angola, Equatorial Guinea, Kazakhstan, Venezuela and, until 2022, Myanmar. The recurring criticism is not that the policies are absent but that the presence of a major western operator supplies revenue and legitimacy to governments that use both against their own populations, a charge the company answers by arguing that withdrawal transfers the assets to operators with no such commitments at all.

Natural gas and liquefied natural gas

Natural gas has become a larger share of Chevron's production than oil in energy terms, and the company frames it as the hydrocarbon with the clearest role in a lower-carbon system, since gas generation emits roughly half the carbon dioxide of coal for the same electricity.

The Australian projects are the centrepiece. Gorgon, on Barrow Island off Western Australia, processes gas from the Gorgon and Jansz-Io fields and was among the most expensive resource developments ever undertaken, with costs rising well above the original estimate. Its environmental approval required the injection of reservoir carbon dioxide into a formation beneath the island, the largest such scheme in the world, which began several years later than planned and has operated below its target rate, drawing criticism from the Western Australian regulator and from campaigners who cite it as evidence of the difficulty of carbon capture at scale.

Wheatstone, near Onslow in Western Australia, processes gas from the Wheatstone and Iago fields together with third-party supply.

In the United States, Chevron's Gulf Coast position and its Permian associated gas feed both domestic demand and the liquefaction terminals that have made the country the largest exporter of liquefied natural gas in the world. The company has contracted capacity at several terminals rather than building its own, preferring to retain flexibility in a market whose long-term demand remains contested.

The Eastern Mediterranean position acquired with Noble supplies Israeli power generation and exports to Egypt and Jordan, and gives the company a role in regional energy diplomacy that carries political exposure alongside commercial return.

Refining

Chevron operates a smaller refining system than several of its peers, a deliberate position reflecting the view that refining earns thin and volatile margins and ties capital to specific geographies.

Its principal American refineries are Pascagoula in Mississippi, among the largest in the country and configured for heavy crude with substantial export capability; El Segundo in California, which supplies a large share of the fuel used in southern California and at Los Angeles International Airport; Richmond in northern California; and Salt Lake City in Utah. It holds interests in refineries in Thailand, Singapore and South Africa through joint ventures and affiliates.

The Californian refineries operate in the most demanding regulatory environment in the United States, producing a fuel specification used almost nowhere else, which means the state's supply cannot easily be replaced from elsewhere when a refinery goes down. Chevron has argued that the combination of that specification, the low carbon fuel standard, cap and trade obligations and proposed profit caps makes continued investment difficult to justify, and the announced closures of competing Californian refineries have lent weight to warnings about the state's future fuel supply. Critics regard the argument as leverage exercised by companies that remain profitable in the state.
