Dynamics of Electric Submersible Pumps
1992This paper deals with the dynamics of electric submersible pumps. Initially the linear torsional oscillations occurring under both transient start-up conditions and steady state excitation by harmonic torques generated from a variable speed drive are described with the aid of a realistic model.

Combined electrical and mechanical model of electric submersible pumps
IEEE Transactions on Industry Applications, 2001The electric submersible pump unit consists of a pump powered by a medium-voltage three-phase induction motor. The power transmission system is integrated with the riser pipes. Starting the pump causes heavy dynamic stresses on the motor shaft and the mechanical connection between pump (impellers) and shaft.

System Grounding of Electric Submersible Pumps
SPE Production Engineering, 1987Summary To ground or not to ground? That is the question. This paper assists in answering that question. Proper system grounding of electrical submersible pumps has long been an issue for debate. Some believe that an ungrounded system is best, whereas others are equally convinced that the opposite is true.

The Effects of Abrasives on Electrical Submersible Pumps
SPE Drilling Engineering, 1990SummaryThe electrical submersible pump (ESP) is a high-speed rotating device. Its operational life in oil wells can depend on the type and quantities of abrasives present in the produced fluid. This paper reports on a set of experiments performed in a specialized abrasive test loop. In the test, the size and quantity of abrasives were varied along with

Depth Constraint of Electric Submersible Pumps
SPE Production & Facilities, 1994Summary This paper summarizes the various factors that limit electric submersible pump (ESP) operation at increasing depth. It explores in detail two parametrically related constraints, pump-shaft horsepower capacity and thrust-bearing load capacity. The former limits the product of head and rate; the latter limits head.

Mechanics of an Electric Submersible Pump Failure Mode
SPE Permian Basin Oil and Gas Recovery Conference, 1998Abstract The occurrence of electric submersible pump (ESP) failures due to spinning diffusers is of a tolerable frequency in moderate operating cost circumstances. However, extremely high well servicing expenses are associated with many ESP applications.
