Shale PVT and Sampling


Reservoir Descriptions and Dynamics

Description

This 1-day course was specially developed to complement the SPE workshop on complex reservoir fluids. The major differences between PVT and sampling in ultra-tight formations such as shale versus traditional (>0.001 md) reservoirs will be covered. Discussions include methods to develop black-oil and EOS models to use for liquid-rich reservoir fluids. Topics include:

  • Surface production samples and readily accessible data—what they are and how to use them
  • When 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)
  • Why produced liquids (CGRs) are so much less than initial in-situ fluids

Learning Level

Intermediate

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 and (briefly) EOS compositional PVT modeling.

Who Should Attend

This course is for engineers involved in using or collecting samples, ordering or using PVT data for shale (ultra-tight)reservoirs, and for reservoir, production, and process engineers.

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 to advanced PVT understanding is required.

CEUs

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

Instructor

Curtis Hays Whitson is professor of petroleum engineering at the Norwegian University of Science and Technology (NTNU), Department of Petroleum Engineering and Applied Geophysics. He founded the international consulting company PERA in 1988, as well as Petrostreamz in 2006, a petroleum software company dealing with optimized integrated asset modeling (IAM).

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 over 100 papers, and has written three chapters of edited books.

Whitson consults extensively for the petroleum industry through PERA as staff consultant 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 BS in petroleum engineering from Stanford University and a PhD from the Norwegian Institute of Technology (now NTNU). He is an honorary member of the Society of Petroleum Engineers (SPE), and twice received 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 SPE. He received the 2010 Excellence in Research Award from Statoil for his contributions to gas-based EOR and fluid characterization.
