SC - 16 Gas EOR in Tight Unconventionals

Society of Petroleum Engineers

Thursday, 29 July – Friday, 30 July 2021, 8:00 a.m.–5:00 p.m.  |  Houston, Texas

Who Should Attend

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

This Learning Level is set at: Intermediate

Objectives

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).

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.

Topics

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

Instructors

Curtis Hays Whitson

Curtis Hays Whitson is a professor of petroleum engineering at the Norwegian University of Science and Technology (NTNU). He founded the international consulting company whitson which consults on compositionally-sensitive reservoir processes for most major oil companies worldwide.

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.

Mathias Lia Carlsen

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.
