ESPs have advantages over some of the other artificial lift methods because they can generate a higher formation drawdown and achieve a higher rate. However, their performance is impacted by gas interference and formation sand production, both of which have to be addressed when setting ESPs in production wells. This course will familiarize the user with the ESP system and it's optimum application. All components will be described in detail. The course uses computer software for numerous design and analysis class problems. Some films will be shown to illustrate installation, operation, and removal of failed equipment, new products, and best practices. Discussion is encouraged concerning experiences of successes and failures. Comparisons are made to other lift methods to help facilitate AL method selection.

Problems addressing solids, gas handling and viscosity are addressed. Best practices are stressed throughout so that a long lasting system can be developed for maximum profit. SCADA controls and VSDs are discussed. Participants will learn the function of the various components, and the concerns about installation, operation, and removal of failed equipment. Participants will be able to evaluate the design of a system for current and future conditions, analyze an installed system, and many other operational concerns of the ESP system. New developments are added to the course as they become available to the industry. Although the course uses industry computer software for design and analysis, much of the material is devoted to best practices, which is useful to both engineers and technicians. Deviation is not such a problem with ESPs but is discussed nonetheless. The common practice of using ESPs in unconventional wells with sharply declining production rates is also discussed. One personal computer is provided, at additional cost, for each two participants.
Engineers and field technicians who are responsible for the selection, operation, and maintenance and monitoring of ESP systems.
