West Coyote, on the northern edge of one of the largest oil fields in the Los Angeles Basin, produced about 250 million barrels of oil from sandstone at a depth of about 3,000 feet. Active from 1903 to 1996, it was one of the foundations of the oil industry in Southern California and played a significant role in the early history of both the city of La Habra and Chevron Corporation. On the flat land south of this site, Chevron operated its La Habra Research Laboratory from 1947 to 1999, where personnel made important contributions to mankind's knowledge of geophysics, oil field recovery processes, geology, and engineering, bringing international scientific recognition to La Habra. The diatomaceous shale here is from the Miocene Monterey Formation, collected near San Luis Obispo; this formation is one of the most important to California's petroleum industry because it is rich in organic material, making it a source of petroleum and, where fractured, a good reservoir, and oil and gas fields associated with it occur both onshore and offshore in California.
