PVT in Modeling Horizontal Multi-Fractured Wells in Ultra-Tight Rock
PVT (fluid phase and volumetric behavior) impacts flow modeling in the reservoir, production pipes, and surface process facilities. Several special considerations are required for proper PVT description (sampling and modeling) of ultra-tight/shale formations. This course covers the key issues related to PVT in such systems: sampling, PVT lab tests, in-situ versus produced fluid streams, EOS and black-oil modeling, and transport properties such as viscosity and interfacial tension. A short review of non-conventional thermodynamics is also given, including capillarity and confinement on phase equilibria (e.g. saturation pressure and phase compositions).
- Surface production samples and readily-accessible data – what they are and how to use them.
- When to sample, and how to sample liquid-rich fluids.
- Black-oil PVT model and application to liquid-rich fluids.
- Correlations based on surface production samples.
- Equation of State (EOS) model review and application to liquid-rich fluids.
- Using numerical well models to back-calculated in-situ fluid composition (initial solution GOR).
- Disconnect between in-situ and produced well streams.
- Unconventional thermodynamics: capillarity and confinement
Petroleum or chemical engineer with basic PVT knowledge
Why You Should Attend
Attendees will gain a fundamental understanding of key PVT issues related to development of ultra-tight unconventional resources, from dry gas to gas condensate and high-GOR light oils found in plays such Eagle Ford, Bakken, Montney, Anadarko, and Permian basins.
Who Should Attend
Attendees should attend if they are involved in modeling reservoir or production or surface processes in ultra-tight reservoirs.

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.
