Abstract
Methods and systems for lifting wellbore fluids in a subterranean well towards a surface include providing a closed water system free of fluid communication with the wellbore fluids, the closed water system having a water storage tank located outside of a high temperature zone of the subterranean well. Water from the water storage tank is circulated into the high temperature zone of the subterranean well to form a steam. A downhole steam turbine is rotated by the steam to drive a submersible pump system in fluid communication with the wellbore fluids and the wellbore fluids are lifted towards the surface with the submersible pump system. The steam exiting from the steam turbine is directed towards the water storage tank.
