Paper: Submersible Motor Control

Submersible pumping applications are becoming more and more commonplace in the oilfields. Many oilfield personnel are quite familiar with the beam pump and its characteristics. Just as this unit has served reliably over the years, a properly installed and controlled submersible should give a respectable service life and should pay for its existence many times over. Maximizing the service life of submersible equipment entails the proper utilization and understanding of submersible motor controls. A variety of motor controls and their many features, ranging from simple load-break magnetic circuits to the more sophisticated solid-state monitoring technology, will be presented. This paper will treat not only control junctions but also what benefits the user can realize by proper application and analysis of particular control areas.
