Production Forecast, Reserves Estimates and Reporting Rules for Unconventional Resources


This course teaches the skills and understanding needed to forecast production and estimate reserves in unconventional (ultra-low permeability) oil and gas reservoirs, with an emphasis on shale and tight reservoirs. You’ll learn the basic theories that describe transient and stabilized fluid flow in tight reservoirs, as well as the effect of some of the most common drilling and completion techniques for recovering these resources. This course also provides substantial detail and interpretation of the US Securities and Exchange Commission’s modernized rules for reporting oil and gas reserves as well as the SPE/WPC/AAPG/SPEE Petroleum Resources Management System (PRMS), which is the basis for many of the new SEC reserves definitions. The effects of the new rules on low-permeability reservoir disclosures and recommendations for adapting to the new rules are also discussed.

Why Attend?

There are various ways to forecast production and estimate the size of unconventional gas reservoirs. You’ll learn the strengths and weaknesses of each system and how to develop reliable forecasts in this course.

Who Should Attend

The course is for engineers and geoscientists who are interested in learning how to evaluate unconventional reservoirs.

Special Requirements

W. John Lee holds the Hugh Roy and Lillie Cranz Cullen Distinguished University Chair in the University of Houston’s petroleum engineering program. Prior to this, Lee held the L.F. Peterson Chair in petroleum engineering at Texas A&M University. He was the former executive vice president of S.A. Holditch & Associates, where he specialized in reservoir engineering for unconventional gas reservoirs. He served as an Academic Engineering Fellow with the US Securities & Exchange Commission (SEC) in Washington during 2007–2008, and was a principal architect of the modernized SEC rules for reporting oil and gas reserves.

Prior to beginning is career in academia, Lee managed Exxon’s Major Fields Study Group. He has written many technical papers and three SPE textbooks: Well Testing, Gas Reservoir Engineering, and Pressure Transient Testing. Lee is an Honorary Member of SPE and a member of the US National Academy of Engineering. He received his BChE, MS, and PhD degrees in chemical engineering from the Georgia Institute of Technology.
