Electrical Submersible Pump : Principles, Installation, Operation, Maintenance and Troubleshooting


5-7 Mei 2014, Jogjakarta Plaza Hotel, Yogyakarta

 

 

INTRODUCTION :

This course is to summarize the state of the art of Electric Submersible Pump (ESP) technology. It included the example problems to illustrate the use of various theoretical solutions, it also listed an overview of conventional well productivity and Inflow Performance Relationship (IPR) technology and is general introduction to the latest methods of production optimization using ESP technology. This course compiled as aid to engineers and production people in the Petroleum Industry who have the responsibility of planning and selecting electrically driven submersible pumping equipment. Included are fundamental principles involving sizing, operation and trouble shooting of submersible pump equipment. Also included are tables, data and general information which it will be value to everyone who utilize s submersible pumping equipment. Much material of this course has been published previously and is reassembled in this course. However, there is also a considerable amount of new material included that will assist the participants of the course in their pump selection and operation. Designing a submersible pump installation is not an exact science; it is mostly an art. But it is a talent which can be easily acquired if care and attention are paid to what the well is telling us, and what we want to do with the well. The well conditions vary from one well to other, but the basic information required for a design does not. What we require from a particular well must, of course, be within the limits of the well in question. Submersible pump design provided information required for analyzing the behavior of a productivity well interval using rod pump. This thus makes it possible to answer some fundamental questions:

  • What is the well producing capacity?
  • What fluids do they produce?
  • At what flow rates?
  • What is the submersible pump to use?

In this course, it has also included example problems to illustrate the use of various theoretical solution. Wherever possible, it has not only discussed practical difficulties that one may encounter while using the theoretical solutions, but it has also listed some of the method that one can used to obtain the desired information. It also included descriptions on field histories wherever they were available and troubleshooting using submersible pump.

This course is mainly directed to the practicing professionals who make engineering calculations and decision on submersible pump application and troubleshooting. For managers, the course helps to review the present state of the art. It also outlined some of new method in artificial technology exist today. These gaps in technology will be useful for research engineers and research professionals to determine the areas of future research.
