E-465 - Well Inflow & Outflow Performance

  • Reservoir or well performance engineers and technicians
  • To deepen knowledge of well lift optimization and master use of the software program Prosper
Learning Objectives
  • To build a PVT model which will be used in a well performance study
  • To analyze the link between reservoir characteristics and production
  • To understand how wells can produce naturally
  • To understand the main artificial lift methods and their use
  • To model and understand crucial parameters of well performance
  • To identify reasons for poor well performance
Ways and means
  • Multimedia online learning with personal coaching
  • Before training starts, 2 hours are dedicated to introduce the training agenda, methods and tools
  • The exact needs and expectations of each participant are also assessed and discussed (MCQ and phone interview with the tutor)
  • During the training, individual phone contact with the tutor and web conferences with other participants
  • Use of the software program PROSPERā„¢ (license not provided)
Total duration of the training is 32 hours, spread over an 8-week period
