WHO SHOULD ATTEND: Production, reservoir, completion, drilling and facilities engineers, analysts, operators, and anyone interested in learning about the implications of Electrical Submersible Pump (ESP) systems for their fields and reservoirs.
COURSE DESCRIPTION: The course covers the basic design principles of one of the most common artificial lift methods, Electrical Submersible Pumping, illustrated with many classroom examples. The proper design of ESP installations is a technical and economic problem. The course starts with a short overview of fundamentals and deals with well inflow performance, hydraulics, electrics, and a basic description of NODAL Analysis principles. The basic components of the ESP system: the pump, motor, protector, electric cable, are fully described by introducing their main structural and operational features. Trainees solve examples and class problems throughout the course. Animations and videos reinforce the concepts under discussion.
Special well conditions like high viscosity fluids, free gas production, and abrasive materials require special equipment completely covered during the course. A brief discussion on ESP application in unconventional wells is included. The course covers the application of Variable Speed Drives and their advantages in producing oil wells. The special feature of this course is a discussion of digital oilfield and a brief review of machine learning applications in the operations of ESPs.
Option: Client’s real-time system-based workflows and examples can be incorporated in the class discussions. Requires two-days of consulting and access to the client system at least 4 weeks before the class.
