A deep well pumping apparatus utilizing a geothermal source of energy is disposed within or above a stratum having a cool irrigating fluid, and an associated heat exchange unit is disposed within a stratum having the geothermal source. An organic working fluid is conveyed under pressure through the heat exchange unit and applied as a gas to a turbine assembly operatively coupled to the pump. The spent working fluid and cool irrigation fluid are then conveyed to the surface.
