Beaverton Oil is an oil refinery situated in Beaverton. It appeared in Season Nine episode "Two Days Before the Day After Tomorrow".
Background[]
Stan, Cartman, and Kyle attempted to rescue the residents of Beaverton from a flood (after the government had decided not to). They took a speedboat on their way to Beaverton, but had lost control of the boat, before crashing into an oil factory, causing oil spillage into the flooded waters, which burned in the process. With no way out of the factory, Stan makes a phone call to Randy Marsh asking for his help, instead of telling the truth of what caused the flood in Beaverton.
As a helicopter arrived to rescue the boys, Cartman held Kyle back, demanding that the latter hand over his Jew Gold. However, Kyle threw it into the burning oil instead, before ditching Cartman on the way to the helicopter. The boys were eventually evacuated out of the factory, with Cartman hopping on board at the very last second.
