Overview

The Electrical Submersible Pump (ESP) is an artificial lift system that consists in a centrifugal multistage downhole pump that is driven by a downhole electric motor energized by a cable from the surface. Despite of being commonly used there are some conceptual and operational aspects that are not clearly understood and require a detailed review to ensure proper application of this method.

ESPs are used in wells that cease to flow or to boost production in wells that can flow naturally. The design and optimization of the ESP system aims to reduce the flowing bottom pressure through the increased pressure provided by the multiple stages which allows to overcome the weight of the column, the friction and the back pressure existing on the surface. This method is particularly attractive due to its ability to handle high production rates.

In order to have an adequate ESP operation, it is necessary to select the appropriate wells for its use based on the advantages and limitations of the method, understand each of its components, know the design / sizing process of the equipment, and its optimization.

Objective

To understand the theoretical foundations of the method of artificial lifting by Electrical Submersible Pump and the interrelation of all the components that make up this system.
