The company’s origins are traced to the 1879 Pico Canyon oil discovery and Pacific Coast Oil, formed on 10 September that year. Standard Oil of New Jersey acquired it in 1900; it remained separate until combination with Standard Oil (California) in 1906. Shipping began with Pacific Coast Oil in 1895 and Standard Oil in 1898. The 1911 trust dissolution made the California concern independent. Acquisition of Pacific Oil in 1926 led to reincorporation as Standard Oil of California, or SOCAL. Rosanoski distinguishes Pacific Oil from Pacific Coast Oil tentatively and notes conflicting accounts of the California names.
Caltex was formed with The Texas Co. in 1936. The partners also held interests in Bahrain Petroleum, California Arabian Standard Oil, later Aramco, and Nederlandsche Pacific Petroleum, later Caltex Pacific Indonesia. Signal Oil was acquired in 1947 and Standard Oil of Kentucky in 1961. Gulf’s acquisition is dated to early 1984 in one source and 1985 in another.
The Chevron name was adopted in 1984 according to the later company and Lloyds account; Thompson places it after the 1985 Gulf purchase. Rosanoski rejects earlier register claims of a 1984 California/Pacific merger. By 1980–1981 vessels had apparently moved under Chevron USA. Shipping subsidiaries included California Shipping, California Tanker, California Transport and Foreign Tankship. California Shipping and later Chevron Shipping operated the fleet. Talbot-Booth’s supposed control of Anglo-American and Standard Oil of New Jersey is identified as erroneous in the source; it also lists operation for Standard Oil of Indiana.
