The company is based in San Ramon, California, United States of America and has a global workforce consisting of approximately 62,000 employees and about 5,800 service station employees.

In 2007, Chevron produced 2.62 million barrels of oil-equivalent per day. About 70 percent of that volume occurred outside the United States and in more than 20 different countries. Chevron had a global refining capacity of more than 2 million barrels of oil per day at the end of 2007. The company has invested in 13 power-generating facilities in the United States and Asia.

Chevron in the UK

Chevron have interests in nine oil-and-gas-producing fields in UK waters and also owns the Pembroke refinery in southwest Wales, which specializes in processing heavy, lower-quality crudes.

Their offshore operations are spearheaded from their offices in Hill of Rubislaw, Aberdeen. This new office complex was set up to provide research, development and technical services not just for the UK but for Chevron worldwide. When fully staffed it is expected to house over a 100 technology professionals.

Chevron's top 3 producing fields are:
  • The Captain field: Operated by Chevron who have an 85% interest in the field. Located 68 miles north of Aberdeen, Captain is a 4 legged platform sitting in water depths of 105 metres, bridge linked by a 68 metre walkway to the Wellhead Protector Platform. In 2007 total daily production averaged 51000 barrels of oil per day and 10 million cubic feet of gas per day.
  • The Britannia field: Jointly operated by Chevron who have a 32.4% interest. Britannia's total daily production averaged 19000 barrels of oil per day and 437 million cubic feet of gas per day.
  • The Alba field: Operated by Chevron who have an 23.4% interest in the field. Located 130 miles north east of Aberdeen this field was discovered in 1981 with first oil produced in 1994. The Alba platform sits in water depths of 138 metres and averaged 43000 barrels of oil per day in 2007. The oil produced is pumped from the platform 3km to a permanently moored floating storage unit from where it is offloaded by tanker for further transportation to refineries.
Chevron's other interests include:
  • The Erskine field: The Erskine platform is an unmanned facility located 150 miles east of Aberdeen. Discovered in 1981 first oil flowed in 1997, due in part to the extreme pressures (14000 psi) and temperatures (350 deg C) encountered.
  • Elgin/Franklin: Chevron holds a 3.9% equity.
  • Jade: Chevron holds a 19.9% equity.
  • Callanish and Brodgar: These 2 Britannia satellites are expected to begin production late 2008. Chevron holds a 16.5% and 25% equity respectively.
  • Alder: Located about 17 miles west of the Britania field, Alder is another high temperature high pressure field. Start up is likely in 2012. Chevron holds a 70% equity and is operator of the project.
The Pembroke refinery was opened in 1964. This is one of Chevron's 7 major refineries. It can process 220000 barrels of crude per day to produce 17 products including petrol, diesel, kerosene and LPG petrochem feedstocks. It boasts one of the worlds finest natural harbours allowing some 1800 vessels to dock there each year.
