chevron.comChevron's origins date back to 1879 as the Pacific Coast Oil Company. It became Standard Oil of California (Socal) after the Standard Oil breakup. Through decades of mergers—including with Gulf Oil in 1984 and Texaco in 2001—the company grew into one of the world's largest energy firms. In 2022, Chevron announced its headquarters relocation to Houston.
Chevron operates in more than 180 countries and has major upstream assets in the Permian Basin, the Gulf of Mexico, Australia (Gorgon and Wheatstone LNG), and Kazakhstan (Tengiz). Its downstream operations include refineries across the Americas and Asia-Pacific.
