Shale PVT and Sampling

Disciplines: Reservoir

Course Description

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 Attends

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.

Cancellation Policy

All cancellations must be received no later than 14 days prior to the course start date. Cancellations made after the 14-day window will not be refunded. Refunds will not be given due to no show situations.

Training sessions attached to SPE conferences and workshops follow the cancellation policies stated on the event information page. Please check that page for specific cancellation information.

SPE reserves the right to cancel or re-schedule courses at will. Notification of changes will be made as quickly as possible; please keep this in mind when arranging travel, as SPE is not responsible for any fees charged for cancelling or changing travel arrangements.

We reserve the right to substitute course instructors as necessary.

Multiphase RTA for Tight Unconventionals
Mathias Carlsen

Two common goals of Rate Transient Analysis (RTA) are the quantification of early time well performance using the Linear Flow Parameter (LFP), as well as the contacted pore volume being drained (e.g. OOIP and OGIP). These two parameters are essential f...
