ABSTRACT:
A fluid driven power system is located in a borehole for driving a downhole pump for pumping water to the surface. An uphole pump driven by a windmill is provided for pumping fluid from a storage system downhole for operating the fluid driven power system. An energy storage system is provided for operating the downhole fluid driven power system when the wind velocity is low. The energy storage system comprises a fluid accumulator which is pressurized by fluid from the uphole pump during low velocity wind. As the pressure in the accumulator builds up to a certain level, fluid from the accumulator is released to operate the downhole fluid driven power system.
