Unconventional Reservoir Production (Rate-Transient) Analysis

Management and Information Reservoir Descriptions and Dynamics


This course provides an overview of the state-of-the-art in unconventional gas (shale gas, tight gas, and coalbed methane) and light oil (shale oil, tight oil, and “halo” oil) well production analysis. Unconventional reservoir properties are first reviewed, followed by a discussion of production analysis in the context of a field development optimization workflow. The concept of rate-transient analysis (RTA) is introduced, and example theoretical rate-transient signatures for fractured vertical and multi-fractured horizontal wells are reviewed.

An overview of analytical methods for RTA is then provided, including a discussion of how these techniques can be modified to account for unconventional reservoir properties such as multi-phase flow, non-static permeability, non-Darcy flow, and desorption. Empirical methods for production analysis are also briefly reviewed. Tight gas, shale gas, tight oil, shale oil, and coalbed methane field examples are provided to illustrate application of the techniques.

Chris Clarkson, P.Eng., is president of UROC Consulting. He is also a professor in the Department of Geoscience and the EnCana chair in Unconventional Gas Research at the University of Calgary. His research is investigating critical issues of importance to the industry through a comprehensive analysis of unconventional plays in western Canada.

A technical paper by Clarkson won the Rossiter W. Raymond (AIME) and Alfred Noble Prize (ASCE) for exceptional merit at SPE’s Annual Technical Conference and Exhibition in 2005. Clarkson also served as  a 2009–2010 SPE Distinguished Lecturer. His topic was “Coalbed Methane: What Secrets Remain Hidden in the Black Box.”

Clarkson earned his PhD from the University of British Columbia in 1998.
