ABSTRACT:
A method to enhance oil production from producing formations using a pressure differential created by evacuating a recovery hole cased through the overburden into the producing formation, and directionally injecting under pressure, into an injection hole in communication with the producing formation, a heated hydrocarbon solvent with surfactant added a distance from the recovery hole. The heat, solvent, pressure differential and surfactant will increase the flow of crude into the recovery hole.
