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


Easily the most recognizable of the companies operating under the Poseidon name, Poseidon Oil did not limit itself only to the excavation and pumping of petroleum - it also operated a number of nuclear power plants, one of which was Atomic Powerplant № 5 in Gecko.[1][2] Major installations belonging to this corporation were the Poseidon Oil Rig,[1][3] later used as the headquarters of the Enclave on the Pacific Ocean, and the Navarro Refinery[1] on the coast of California.

Together with the Enclave, Poseidon Oil helped finance Senator Todd Peterson's secret bunker.

    A. Ron Meyers: "{141}{}{There's a big Poseidon oil rig left out on the water. That's the final base of the Enclave, and unless I miss my bet, that's where your friends are, too.}"
    The Chosen One: "{143}{}{What else is going on out there on the rig?}"
    A. Ron Meyers: "{148}{}{Beats me. I was a Navarro tech, not a rig operator. We talked to them over the comm lines, and that was about the extent of it.}"
