Under consignment to the Allied Forces during World War II, the Bahrain refinery’s capacity increases to 115,000 barrels a day.

After the war, Caltex ups its bunkering service, boosts the manufacture of lubricating oil and asphalt sales, and dramatically increases its refining capacity.

Socal and Texaco are partners in the California Arabian Standard Oil Co. (later Aramco), which soon becomes the most prolific oil producer in the world.

Caltex enters a joint venture with Nippon Oil Corporation subsidiary Tokyo Tanker Co., which launches its first supertanker, Nikko Maru, and the world’s largest tanker at that time, Tokyo Maru.

Caltex builds the Philippines’ first petroleum refinery, the Batangas Refinery, on a 300-acre site along the waters of Batangas Bay, about 72 miles south of Manila. Caltex commissions close to 20 new refineries from 1952 to 1966.

Constructing Australia’s Kurnell Refinery enables Caltex to process and distribute the increasing production from Caltex Pacific Indonesia’s Minas and Duri Fields.

Japan leads the world in demand, buying 11 million barrels of Caltex products. In the 1960s, Caltex’s product sales increase more than 10 per cent a year and its operations extend to more than 70 countries.

Socal and The Texas Co. divest Caltex of all its European assets following moves by Texaco to extend its interests in the Western Hemisphere. This episode is atypical in an otherwise harmonious and long-lived partnership.

Caltex’s advertising message stresses its multicultural employee base: “As a responsible petroleum marketer doing business in three continents flying over 60 different flags, Caltex has thrived under a simple yet sensible corporate policy… to employ, train, and advance citizens of each and every country where the Caltex Star shines.”

Caltex purchases Golden Fleece Petroleum and its 1,100 retail outlets, making it Australia’s second largest marketer of petroleum products.

Caltex expands and upgrades most of its 14 refineries to meet the needs of the rapidly growing Pacific Rim nations. Capping the list is the $1.7 billion, 130,000-barrel-a-day Star Refinery in Map Ta Phut, Thailand, a leader in design, safety features and pollution controls that will open in 1996.

The company changes its name to Caltex Corp., dropping ‘Petroleum’ from the name because non-petroleum products are becoming a growing source of revenue.

Caltex becomes a part of ChevronTexaco Corp.

ChevronTexaco Corp changes its name to Chevron Corporation.

Forbes’ describes Caltex as “the jewel in [Chevron’s] crown”. Chevron Corporation is currently one of the world's leading energy companies. With more than 53,000 employees, Chevron subsidiaries conduct business in approximately 180 countries around the world, producing and transporting crude oil and natural gas, refining, marketing and distributing fuels and other energy products.
