ABSTRACT:
Apparatus for recovery of liquid hydrocarbons from on top of ground water in which a recovery unit is used which sinks in the liquid hydrocarbon and floats on water. The sinking of the recovery unit allows liquid hydrocarbons to enter the unit so that they can be pumped out of the unit to a holding tank. Members are provided to center the unit in a well casing and hold it in a vertical position; these members are also used as conduits to pass liquid hydrocarbons, air, and water.
