Poseidon Oil

Poseidon Oil was a subsidiary of Poseidon Energy before the Great War.

Background
Easily the most recognizable of the companies operating under the Poseidon name, Poseidon Oil did not limit itself only to the excavation, pumping, and transport of petroleum - it also operated a number of nuclear power plants, one of which was Atomic Powerplant No. 5 in Gecko. Major installations belonging to this corporation were the Poseidon Oil Rig, later used as the headquarters of the Enclave in the Pacific Ocean, and the Navarro Refinery on the coast of California.

Behind the scenes

 * Poseidon Oil would have played a minor role in Van Buren, as one of the sources of funding for the Maxson Bunker and the takeover of Tibbets Prison.
 * Chris Avellone shared concept areas about Poseidon Oil in Fallout Bible 8.

Appearances
Poseidon Oil appears in Fallout 2.
