Comparative Simulation Studies of ESP Permanent Magnet and Induction Current Motors in ESP Selective Applications

Abstract

Abstract Induction alternating current (AC) motors (IACM) have been used in electrical submersible pumps (ESP) due to them being more cost effective and easier to manufacture compared with other type of motors used in ESP systems. With increase of oil demand globally, the application of electrical submersible pump systems also increased. Therefore, optimizations of ESP systems are needed. This paper will discuss and simulate both types of ESP motors, which are: induction AC motor and permanent magnet motor in ESP systems, with emphasizes on why some application are better suited for permanent magnet AC motor and others for induction current type motor. The option of choosing the optimum motor type is dependent on multiple factors that may include: ESP design reliability, wellbore complexity and completion strings, production requirements, reservoir fluids characteristics, power supply limitations and ESP designs challenges.
