E-323 - Drilling & Completion - Wellbore Interface & Well Productivity

  • Newly-hired and 2-3 years experienced reservoir engineers, reservoir geologists, production engineers and experienced technicians willing to deepen their knowledge in drilling, completion, wellbore interface and well productivity; young scientists, geoscientists and petroleum engineers moving towards reservoir engineering.
  • This course provides a comprehensive knowledge about fundamentals of drilling, completion, wellbore interface and well productivity applied to Reservoir Engineering concerns.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • describe main drilling equipment and operations,
  • describe main completion equipment, operations and configurations,
  • describe main concepts of reservoir-wellbore interface and to choose an interface adapted to the conditions encountered in the reservoir,
  • discuss main concepts of wells productivity, included inflow, outflow and skin, to detect problems holding down wells productivity and to select adequate solutions.
  • No prerequisites for this course.
