Octane Springs is a large oil field in eastern Bone County, San Andreas. Its pumps and derricks, which can be easily spotted from the nearby tracks of the Brown Streak Railroad, service Green Palms, the refinery located immediately to the west. To the northwest of Octane Springs is Area 69, while to the south is Hunter Quarry. Meanwhile, east of the oil field is already Las Venturas, specifically the Blackfield district. Many of the moving components on the oil rigs are not solid and the player will pass right through them. Octane Springs resembles oil wells in Railroad Valley, Nye County, Nevada.
