An extensive electrical and mechanical testing program has been performed on beam pumping systems in six producing properties in the Permian Basin of Texas. The subject properties are waterflood or carbon dioxide (C02) flood projects which produce from the San Andres formation. The effect of motor torque mode setting and direction of rotation was studied in 30 wells. The impact on important operational indicators such as electrical lifting cost, gear box loading, and rod loading are addressed. It should be noted that much of the data used in this paper was the subject of a paper entitled "Application of Real-Time Measurement of Motor Power to Determination of Beam Pump Efficiency" which was presented at the 1994 Southwestern Petroleum Short Course. Because more data has since been obtained, the conclusions below are more statistically significant.
