The Murrieta Oil Field is an industrial area in metropolitan Los Santos, bordering East Los Santos to the west and the Palomino Highlands to the east. This area is supposedly rich in petroleum or crude oil deposits. The land contains various Brute pump jacks, which bob up and down to pump the crude oil from the ground.

- One of the 50 stunt jumps is performed near one of the factory buildings.
- The name "Murrieta" could be a reference to the city of Murrieta, California, named after Juan Murrieta, a Spanish land owner in California in the late 19th century.
