A study of a mature onshore field with more than 70 rod-pumped wells found several ways for improving pumping operations. The profitability of rod pumping is a direct function of the energy ...

Abstract: Disc-type permanent magnet motors are critical equipment for enhancing the efficiency and reliability of beam pumping units. This paper proposes a multi-objective optimization design method ...

A pilot project on a portable variable-speed-drive and load cell for obtaining counterbalance effect (CBE) data in the Duri steamflood improved the sucker-rod pumping efficiency from wells that had ...
