32 hours PRO/BLPROSPER
Level
Proficiency
Audience
  • Reservoir or well performance engineers and technicians.
Purpose
  • This course aims a deepen knowledge of well lift optimization and master use of the software program Prosper.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • build a PVT model which will be used in a well performance study,
  • analyze the link between reservoir characteristics and production,
  • model and analyze crucial parameters of well performance,
  • identify reasons for poor well performance,
  • select and design the adequate artificial lift methods.
Prerequisite
  • No prerequisites for this course.
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 PROSPER™ (license not provided).
Observation
Total duration of the training is 32 hours, spread over an 8-week period.
