ABSTRACT:
A fluid recovery system for producing subsurface oil and water deposits comprises a high capacity pump such as a high capacity centrifugal pump that is immersed within the deposit, a well casing that extends into the deposit from the surface, a source of rotatory motion power, and a power transmission system that connects the power source and the pump in the well casing. The power transmission system includes a step up transmission and a rod string which interconnects the power source and the step up transmission to deliver rotary motion to the step up transmission. The pump is connected to the step up transmission for delivery of higher speed rotary power to the pump. A method of operating the fluid recovery system is also disclosed.
