5 days
GRE/EOR-G
Sessions
This course is not scheduled.
Who should attend?

Audience

    • Reservoir engineers involved in miscible gas injection EOR projects.

Level

  • Proficiency
  • This course provides a thorough understanding of the miscible gas injection method and its connection to the fundamental mechanisms of oil reservoir production. It also provides information for decision making in miscible gas injection EOR projects based on the presentation of the main displacement mechanisms, the related screening criteria, dedicated simulation software and field cases.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • describe recovery expectations from reservoirs under primary, secondary and tertiary methods,
  • describe main Enhanced Oil Recovery methods and explain the way they achieve higher recovery factor,
  • explain miscible gas injection mechanisms and related screening criteria,
  • list gas used in miscible gas injection method and compare their way of affecting oil recovery,
  • design and apply miscible gas injection method using empirical, analytical and simulation tools and finally evaluate its related performance.
