ABSTRACT:
The pump and pump system of the present invention is designed to remove liquids, gas, sand and coal fines from gas and/or oil well bores. There is a need in the oil and gas industry to develop a more efficient operating pump that is capable of operating in wells that do not have enough bottom hole pressure to lift liquids to the surface causing the well to log off with fluids and if not economic, potentially be plugged prematurely. Additionally, this design will allow the producer the ability to conduct well bore maintenance such as acid flushes for perforation cleaning and scale batch treating for continued scale treatment.
