Learning Objectives

  • Upon completion of the course, participants will be able to:
  • discuss the natural mechanisms of production of Oil & Gas reservoirs and their corresponding expected performance,
  • discuss the mechanisms of secondary recovery through water injection and non-miscible gas injection and their related expected performance,
  • list the main Enhanced Oil Recovery methods and discuss their mechanisms and corresponding expected performance,
  • describe typical EOR projects workflow and related screening criteria and economics,
  • carry out simple material balance calculations for matching reservoir parameters/forecast recovery.

Ways & Means

  • Interactive lectures and exercises.
  • Real field case studies.
  • Hands-on practices using dedicated industrial software for PVT matching, history matching and production forecast through material balance.
