Oil's Well

A version with improved visuals and without Mitchell's involvement was released for MS-DOS in 1990.

The player collects oil for a drilling operation by moving the drill head through a maze using four directional control buttons. The drill bit is trailed by a pipeline connecting it to the base. Subterranean creatures populate the maze; the head can destroy the creatures, but the pipeline is vulnerable. As the player traverses the maze, the pipe grows longer, but pressing a button quickly retracts the head. There are 8 levels to play through.

ANALOG Computing said that Oil's Well for the Atari 8-bit was a "truly different and challenging" variant on the "'gobble the dots' theme", with good gameplay and graphics. Dave Stone in Computer Gaming World stated that "The action's well-paced, the difficulty progressive. While getting to a higher level is somewhat dependent on getting the right breaks — good eye-hand coordination, timing, and strategy are essential". Ahoy! stated that while the Commodore version's graphics and sounds were only "serviceable; gameplay is, in my experience, unique... Recommended". InfoWorld called the IBM PCjr version "a clever, basic game", and InfoWorld's Essential Guide to Atari Computers cited the Atari 8-bit version as "Sierra's trickiest". The U.S. gaming magazine Computer Games awarded Oil's Well the 1984 Golden Floppy Award for Excellence, in the category of "Maze Game of the Year."

Despite already being a clone of Anteater, several additional clones borrowed the theme of Oil's Well: Pipeline Run for the Commodore 64 in 1990 and Oilmania for the Atari ST in 1991.
