Chevron Corporation is one of the world’s largest global energy companies. Headquartered in San Ramon, California, USA and active in more than 180 countries, it is engaged in every aspect of the oil and gas industry, including exploration and production; refining, marketing and transport; chemicals manufacturing and sales; and power generation. Chevron is one of the world’s six “supermajor” oil companies.
Chevron was originally known as Standard Oil of California, or Socal, and was formed amid the antitrust breakup of Standard Oil in 1911. It was one of the “Seven Sisters” that dominated the world oil industry during the early 20th century.
In 1984, the merger between Chevron and Gulf Oil became the largest merger in world history at the time. Because of its size, Gulf divested many of its worldwide operating subsidiaries and sold some Gulf stations and a refinery in the eastern United States to satisfy US antitrust requirements. In 2001, the former Chevron corporation merged with Texaco to form ChevronTexaco. On May 9, 2005, ChevronTexaco announced it would drop the Texaco moniker and return to the Chevron name. Texaco will remain as a brand under the Chevron Corporation. On August 19, 2005, Chevron merged with the Unocal Corporation, a move which, because of Unocal’s large South East Asian geothermal operations, made Chevron the largest producer of geothermal energy in the world.
