W John Lee, PhD – Research Fellow


A world-renowned expert in the field of petroleum reservoir engineering, John Lee, holds BS, MS and PhD degrees in Chemical Engineering from The Georgia Institute of Technology and has been a leader in our industry for over five decades. He is best known for his recent publications and presentations on oil and gas reserves regulations and estimation, and production forecasting in unconventional gas reservoirs.

The author of four textbooks published by the Society of Petroleum Engineers, Dr. Lee has received numerous awards from that organization, including the Lucas Medal, the DeGolyer Distinguished Service Medal and the Society’s highest recognition - Honorary Member. He served as an Academic Engineering Fellow with the U.S. Securities & Exchange Commission (SEC) and was a principal architect of the modernized SEC rules for reporting oil and gas reserves.

Prior to entering the world of academia, Dr. Lee enjoyed a long professional career with Exxon, eventually heading Exxon Company, USA's major fields study group, where he supervised integrated field studies of Exxon's largest domestic reservoirs. He later joined the Petroleum Engineering faculty at Texas A&M, becoming Regents Professor of Petroleum Engineering and serving as a consultant with S.A. Holditch & Associates, where he specialized in reservoir engineering aspects of unconventional gas resources.

Dr. Lee is a Professor of Petroleum Engineering in the Harold Vance Department of Petroleum Engineering at Texas A&M University, and past holder of the Cullen Distinguished University Chair at The University of Houston.


John serves as Research Fellow with 3esi-Enersight, and is available to clients for consultations and advice on reserves and reporting for SEC compliance. He conducts independent research in reservoir engineering for unconventional resources to ensure our knowledge base remains current, providing us with the proper foundations on which to further our product development. Dr. Lee also mentors our technical and engineering staff, sharing his current research and the vast knowledge he has acquired throughout his distinguished career.
