In September 1879, the Pacific Coast Oil Company was created. They kept the name until 1906, when it merged with a Standard Oil subsidiary and became Standard Oil Company (California). Standard Oil of California and Gulf Oil merged in 1984, which became the largest merger in history at that time. The company would change its name to Chevron Corporation the same year. Chevron later merged with Texaco in 2001.
