Gulf

Company History: Gulf Oil was a major global oil company in operation from 1901 to 1985. The eighth-largest American manufacturing company in 1941 and the ninth largest in 1979, Gulf Oil was one of the Seven Sisters oil companies. Prior to its merger with Standard Oil of California, Gulf was one of the chief instruments of the Mellon family fortune; both Gulf and Mellon Financial had their headquarters in Pittsburgh, Pennsylvania, with Gulf's headquarters, the Gulf Tower, being Pittsburgh's tallest building until the completion of the U.S. Steel Tower.

Gulf Oil Corporation (GOC) ceased to exist as an independent company in 1985, when it merged with Standard Oil of California (SOCAL), with both rebranding as Chevron in the United States. Gulf Canada, Gulf's main Canadian subsidiary, was sold the same year with retail outlets to Ultramar and Petro-Canada and what became Gulf Canada Resources to Olympia & York. However, the Gulf brand name and a number of the constituent business divisions of GOC survived. Gulf has experienced a significant revival since 1990, emerging as a flexible network of allied business interests based on partnerships, franchises and agencies.

Successor/Parent History: In 1985, Socal merged with the Pittsburgh-based Gulf Oil and rebranded as Chevron; the newly merged company later merged with Texaco in 2001. Chevron manufactures and sells fuels, lubricants, additives, and petrochemicals, primarily in Western North America, the US Gulf Coast, Southeast Asia, South Korea and Australia. In 2018, the company produced an average of 791,000 barrels (125,800 m3) of net oil-equivalent per day in United States.

Chevron is one of the largest companies in the world and the second-largest oil company based in the United States by revenue, only behind fellow Standard Oil descendant ExxonMobil. Chevron ranked 10th on the Fortune 500 in 2023. The company is also the last-remaining oil-and-gas component of the Dow Jones Industrial Average since ExxonMobil's exit from the index in 2020.
