Gas EOR in Tight Unconventionals

Management and Information

Course Description

The course will discuss the Huff-n-Puff gas EOR process specifically, but will also give a background in the relevant fundamentals of gas EOR methods (miscibility, vaporization, and displacement). Alternative EOR methods will also be discussed. The course is introduced by an industrywide summary of ongoing gas EOR projects in North American unconventionals.


  • 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
  • Gas containment issues
  • Operational considerations including compressor requirements
  • Basic gas EOR economics for unconventionals
  • Example problems

He founded the international consulting company whitson which consults on compositionally-sensitive reservoir processes for most major oil companies worldwide. Whitson is also founder, COB and technical consultant at Petrostreamz which has developed the Pipe-It software and services for value chain model integration and optimization.

Whitson has a BS in petroleum engineering from Stanford University and a PhD from the Norwegian Institute of Technology (now NTNU). He is a Distinguished Member of the Society of Petroleum Engineers (SPE) who twice received the SPE Cedric K. Fergusson award as co-author with Øivind Fevang in 1997 and with Lars Høier in 2001, and received the AIME-SPE Anthony F. Lucas Gold Medal in 2011. He also received the 2010 Excellence in Research Award from Statoil for his contributions to gas-based EOR and fluid characterization. Whitson was elected into the Norwegian Academy of Technological Sciences (NTVA) in 2012.
