John Lee holds the Hugh Roy and Lillie Cranz Cullen Distinguished University Chair at 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 new 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 a Distinguished Member of SPE, a member of the US National Academy of Engineering, and the Russian Academy of Natural Sciences. He received his BS, MS, and PhD degrees in chemical engineering from the Georgia Institute of Technology.




Full Description
 

Description

This course provides participants with the skills and understanding required to forecast production and estimate reserves in unconventional (ultra-low permeability) reservoirs, mostly gas but with some applications to oil. The course will emphasize gas shale and tight gas formations.  On completion of this course, participants will have developed competence in their ability to forecast production and estimate reserves for individual gas and oil wells and reservoirs using state-of-the art methodology.

 Participants completing this course will be able to:

  • Recognize the strengths and limitations of volumetric methods for estimating reserves in unconventional reservoirs.
  • Recognize the strengths and limitations of analog methods for forecasting production and estimating reserves in unconventional reservoirs.
  • Recognize the strengths and limitations of empirical production decline models for forecasting production and estimating reserves in unconventional reservoirs.
  • Recognize the strengths and limitations of analytical reservoir models for forecasting production and estimating reserves in unconventional reservoirs.
  • Recognize the strengths and limitations of numerical reservoir simulators for forecasting production and estimating reserves in unconventional reservoirs.
  • Recognize the strengths and limitations of statistical resource analysis to entire reservoirs.
  • Apply appropriate methodology to typical situations requiring reserves estimates in unconventional reservoirs.

Training course held in Houston in conjunction with the 2011 Reserves and Resources Symposium is co-sponsored by SPE/AAPG/SPEE.
