A new type of pump to be used as a stripper pump for oil wells has been developed by Enersave Pumps, Incorporated of Roswell, New Mexico. The Enersave 500 pump has no moving mechanical parts between the down-hole pistons which lift the fluid and the driving unit at the surface. Rather, a pressure pulse created by the driving unit, usually called the pulser, is transmitted through the fluid in the well string to the down-hole unit and creates the pumping action. Object of the project was to optimize the configuration of the pump, that is, increase the production flow rate while minimizing the energy consumption needed to obtain this flow rate. New Mexico State University's role in this project was to model the pump using computer techniques to provide guidelines for improvement in pump design, to supervise the performance of field and bench testing of the redesigned versions of the pump to validate the actual performance of the pump, and to provide a life cycle cost analysis of the pump. Experimental results at depths to as much as 1729 feet show that the redesigned pump will deliver 3 gpm with an average power input of about 1 hp. The energy requirements of the Enersave 500 pump are on the average 25% lower than the energy requirements of an equivalent pump-jack, the typical pump now used in the oil fields for stripper well operation. Further, a life cycle cost analysis of the Enersave 500 pump compared to an equivalent pump-jack shows the Enersave 500 pump to be more economical to purchase and operate.
