Audience

    • Newly-hired and 2- to 3-year experienced reservoir engineers, reservoir geologists, petroleum engineers and experienced technicians willing to deepen their knowledge in drive mechanisms and EOR: geoscientists, production, drilling and completion engineers moving towards reservoir engineering.

Level

  • Proficiency
  • This course provides a thorough understanding of drive mechanisms, Enhanced Oil Recovery (EOR) and ways to optimize recovery, reserves and field development.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • explain the natural mechanisms of production of oil and gas reservoirs and discuss their related performance,
  • perform simple material balance calculations for matching reservoir parameters/forecast recovery,
  • explain the mechanisms of secondary recovery through water and non-miscible gas injection and discuss their related performance,
  • explain the mechanisms of Enhanced Oil Recovery and describe main EOR methods,
  • describe typical EOR projects workflow, related screening criteria and economics.
