Gas EOR in Tight Unconventionals
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).
The 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.
- 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
- 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
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.
Reservoir engineers, production and completion engineers, process engineers (facilities), EOR technical management, and regulatory professionals.

Curtis Hays Whitson is professor of petroleum engineering at the Norwegian University of Science and Technology (NTNU), Dept. of Petroleum Engineering & Applied Geophysics; he founded the international consulting company PERA in 1988, as well as Petrostreamz in 2006, a petroleum software company dealing with optimized IAM (Integrated Asset Modeling).
Whitson researches and teaches both university and industry courses on petroleum phase behavior (PVT), gas-based EOR, gas condensate reservoirs, integrated-model optimization, petroleum-streams management, liquid-loading gas well performance, and liquids-rich shale well optimization. He has co-authored two books: Well Performance (Golan and Whitson) and the SPE monograph Phase Behavior (Whitson and Brulé), co-authored some 100 papers, and has written three chapters of edited books.
Whitson consults extensively for the petroleum industry through PERA, a specialty consulting company he founded in 1988. PERA staff consult on compositionally-sensitive reservoir processes for most major oil companies worldwide. Whitson is also CTO at Petrostreamz which has developed the new-generation software Pipe-It for optimized IAM.
Whitson has a B.Sc. degree in petroleum engineering from Stanford University and a PhD degree from the Norwegian Institute of Technology (now NTNU). He is an distinguished member of the Society of Petroleum Engineers (SPE), and he received twice the Cedric K. Fergusson award (as co-author with Øivind Fevang, 1997 and Lars Høier, 2001), and the Anthony F. Lucas Gold Medal (2011) from the SPE. He 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.
Mathias Lia Carlsen is GM Americas and a PE consultant at Whitson (earlier PERA) – a global company that has specialized in PVT, gas-based EOR and gas condensate reservoirs since 1988. Carlsen’s main area of work involves reservoir simulation and equation of state fluid characterization. Over the last three years, Carlsen has consulted on and supervised a wide range of projects related to PVT in tight unconventionals. Worth mentioning is the basin-wide EOS model developments in the Bakken, Montney, Eagle Ford, SCOOP/STACK and Permian. Currently, Carlsen is also working on gas EOR (Huff-n-Puff) pilots and field-wide implementation projects in the Eagle Ford, Permian, Bakken and Montney.
In addition to the consultancy, Carlsen researches and teaches industry courses on advanced PVT and phase behavior, EOS model development and gas based EOR. Carlsen holds a MSc degree in Petroleum Engineering from the Norwegian University of Science and Technology (NTNU) and was a Fulbright Scholar at Stanford University.
