Artificial lift plays a crucial role in oil & gas production, especially in mature oilfield. Artificial lift is not only accelerating the production, but also vital to the economic success of the overall development. Therefore, selecting and designing the appropriate artificial lift is important. After completing the course, the participants will possess and enhance the skills necessary to select, design, plan, analyze and optimize the artificial lift system for offshore oilfield. This comprehensive course covers the artificial-lift methods and technologies that fall into two groups, those that use pumps and those that use gas. It provides information and concentrates on the proper selection, operation and maintenance of subsurface pumps so the best economical life can be obtained. It will enhance your knowledge, skills, and attitudes necessary to understand the artificial-lift methods and technologies. It provides the attendees with a thorough understanding of the theory behind all forms of artificial lift, the advantages and limitations of each system, application considerations, and sample performance predictions for each lift method.

This practical course is intended for personnel working indirectly with Artificial Lift Systems who require a fundamental overview of Electrical Submersible Pumping systems (ESP), Progressive Cavity Pumps (PCP), Gas Lift, Beam Pumping Units, Plunger Lift Systems, Jet Pumping Systems and Horizontal pumping Systems.
