Oil Corporation (or just Oil Corp) was a company that specialised in oil. Once Earth had been drained of oil, from the 40th century onward Oil Corp based itself on the desert world of Boukon. They had moving oil rigs to harvest the oil, but the Pirates, like Captain Kaliko, kept bringing down the rigs and stealing the oil.
Oil Corp sent the spy, Swabb, onboard the Black Gold to kill Captain Kaliko and stop her reign of terror. The rigs attacked the pirate ship and it was destroyed. Swabb failed to kill Kaliko, but Kaliko was shortly afterwards murdered by Baltazar. (TV: The Infinite Quest)
