Chevron

Chevron is one of the world's largest integrated energy companies. Headquartered in San Ramon, California, they conduct business in more than 100 countries.

Company Roots.
Chevron traces their earliest roots to a 1879 oil discovery at Pico Canyon, north of Los Angeles, which led to the formation of the Pacific Coast Oil Co. That company later became Standard Oil Co. of California and, subsequently, Chevron.

They took on the name "Chevron" when they acquired Gulf Oil Corp. in 1984, nearly doubling their worldwide proved oil and gas reserves. Chevron's merger with Gulf was at that time the largest in U.S. history.

Another major branch of the family tree is The Texas Fuel Company, which was formed in Beaumont, Texas, in 1901.

It later became known as The Texas Company and eventually Texaco. In 2001, the two companies merged to form ChevronTexaco. The name was changed to Chevron in 2005 to convey a clearer, stronger and more unified presence around the world.

The acquisition of Unocal Corporation in 2005 strengthened Chevron's position as an energy industry leader, enhancing their oil and natural gas assets around the world.
