Oil Ocean Refinery is a location in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a facility in the Great Desert belonging to the Eggman Empire; its purpose is to serve as a refueling station for the new Death Egg.
The Oil Ocean has been maintained by Grandmaster Beauregard Rabbot's Great Desert Dark Egg Legion; they would also protect it from the Sand-Blasters, the Freedom Fighters from nearby Sand Blast City who sought the refinery for themselves. Because of Sonic and Bunnie's actions however, the refinery received heavy damage, making the location useless for some time.
Although badly damaged, the Oil Ocean Refinery was later fueled with energy from the Death Egg, along with the Northern Tundra's refueling station. The local Dark Egg Legion chapter and the Sand Blasters would also continue to wage war over it, with one such confrontation ending when the undercover Mighty the Armadillo destroyed an attacking Legion tank.
- The Oil Refinery is based on the Oil Ocean Zone from the Sega Mega Drive video game Sonic the Hedgehog 2.
