Shale PVT and Sampling

Reservoir Descriptions and Dynamics


This 1-day course is specially developed to complement the SPE Liquid-Rich Basins Conference. The main objective of the course is to convey practical aspects of PVT and phase behavior relevant for tight unconventionals. The course content is a cumulative result of working on engineering problems related to PVT and phase behavior in most of the major unconventional basins in North America; Eagle Ford, Permian, SCOOP/STACK, Montney and Bakken.

Topics include

  • Petroleum fluids
  • Reservoir Fluid Classification
  • Fluid Sampling
  • PVT laboratory experiments
  • Introduction to EOS models
  • Fluid Initialization and In-place Volumes
  • Black-oil PVT model and application to Liquid-rich fluids
  • Separator Shrinkage & Why It Matters
  • Introduction to Gas EOR / Huff-n-Puff

Learning Level


Course Length

1 Day

Why Attend?

Attendees will learn what PVT samples should be collected and how those samples are used specifically in shale. Some discussions include advanced black-oil, EOS compositional PVT modeling and gas-based EOR.

Who Should Attend

Petroleum, reservoir, production, facilities and process engineers. Also relevant for geologists, managers, government representatives and business unit team members exposed to PVT.

Special Requirements

Participants should have some means of note taking. Course materials will be complied in session based on classroom discussion and sent via electronic files after the course. Basic PVT understanding is required.


0.8 CEUs (Continuing Education Units) will be awarded for this 1-day course.

Mathias Lia CarlsenMathias 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.
