Oil's well was released for the Colecovision in 1983. In the game you play an oil factory, yes an oil factory. You have to send your lone oil pipe down underground to collect oil. You have to collect all the oil on the level to advance to the next one. This is one of the trickier bits of the game, the further down you go the more oil there is but there are also animals (Badgers, Moles, and Turtles) that try to cut the oil line. Pesky little critters.
