Chevron Corporation is an American multinational energy corporation predominantly specializing in oil and gas. The second-largest direct descendant of Standard Oil, and originally known as the Standard Oil Company of California, it is active in more than 180 countries. Within oil and gas, Chevron is vertically integrated and is involved in hydrocarbon exploration, production, refining, marketing and transport, chemicals manufacturing and sales, and power generation. Founded originally in Southern California during the 1870s, the company was then based for many decades in San Francisco, California, before moving its corporate offices to San Ramon, California, in 2001; on August 2, 2024, Chevron announced that it would be transferring its headquarters to Houston, Texas. Chevron traces its history back to the second half of the 19th century to small California-based oil companies which were acquired by Standard and merged into Standard Oil of California. Wikipedia
