Who Should Attend

Reservoir engineers, production and completion engineers, process engineers (facilities), EOR technical management, and regulatory professionals.


To learn about and share experiences in gas EOR in tight unconventionals. The course lectures and visual presentations are video recorded and made available to course participants. The instructor has worked on a number of commercial gas EOR projects in tight unconventionals.

Course Content

Gas-based EOR in tight unconventionals is a growing application to tap the vast unproduced oil and condensate resources in liquid-rich shale basins. The Huff-n-Puff process now involves several hundred wells in the Eagle Ford, and pilots are planned or ongoing in all other liquid-rich basins (Bakken, Permian, and Montney).

This course will discuss the Huff-n-Puff gas EOR process specifically, but will also address relevant fundamentals of displacement-based gas EOR methods (miscibility, vaporization, and displacement) in tight unconventionals.


Day one:

  • Introduction to Unconventional gas EOR
  • Summary of gas EOR methods and recovery mechanisms
  • What makes unconventional gas EOR different than conventional?
  • Huff-n-Puff process
  • Miscibility, PVT and injection gas selection relevant to H-n-P process

Day two:

  • Review ongoing industry gas EOR projects in North America unconventionals
  • Operational considerations including compressor requirements
  • Gas containment issues
  • Basic gas EOR economics for unconventionals
  • Reservoir modeling strategies
  • Alternative-to-HnP/Displacement EOR processes in tight unconventionals
  • Pre-worked example problems with Q&A and discussion
