A study showed that beam pumps, for the range of depths and rates studied, were always more energy efficient than electric submersible pumps (ESPs). In fact, the ESPs had lower efficiency and the beam pumps were more efficient than expected. The data are from a West Texas field. The study's object was to find a production rate above which EPSs are more energy efficient and below which beam pumps are more efficient. Many types of formulas are in use with varying degrees of sophistication or approximation. This paper reviews several equations for which the literature contained measured data for calculating the efficiency of artificial lift installations.
