This paper presents the results of a study that compares the theoretically calculated power consumption of a Hydraulic Gas Pump, rod pumps, and electric submersible pumps. The results indicate that, depending on the flowing bottomhole pressure of a well, a Hydraulic Gas Pump can have lower power costs than a rod pump or a submersible pump.

We present a method for calculating the power cost of a Hydraulic Gas Pump and discuss the relationship of the power cost of this pump to the flowing bottomhole pressure. Several graphs compare the calculated power consumption of a rod pump, submersible pump, and Hydraulic Gas Pump for well depths ranging between 6,000 and 10,000 feet; flowing bottomhole pressure ranging between 500 and 2,000 psi; and production rates of 300 and 500 BLPD.
