Summary
Business Impact: This course provides engineers, geoscientists, and decision makers with the skills and understanding required to forecast production and estimate reserves in unconventional (ultra-low permeability) oil and gas reservoirs. The course will emphasize oil/gas-shale, as well as tight oil and gas formations.
Forecasts of future production and reserves are fundamentally important in evaluating the economics of any resource development and operation, and are critical for the evaluation of unconventional oil and gas resources, allowing for better business decisions. More accurate forecasts and reserves estimates also lead to greater credibility with investors in both public and private companies.
Duration and Training Method
A virtual classroom course divided into 8 webinar sessions over a two-week period (equivalent to a four-day classroom course), comprising lectures, discussion, case studies, and practical exercises to be completed by participants during and between sessions.
Participants, including geoscientists, engineers, and decisionmakers will learn to:
- Appraise the strengths and limitations of empirical production decline models for forecasting production and estimating reserves in low permeability reservoirs.
- Predict future production and reserves using empirical production decline models in low permeability reservoirs.
- Evaluate the strengths and limitations of theoretical production decline models for forecasting production and estimating reserves in low permeability reservoirs.
- Predict future production using theoretical production decline models in low permeability reservoirs.
- Judge the strengths and limitations of selected rate-transient analysis and reservoir stimulation techniques for forecasting production and estimating reserves in low permeability reservoirs.
- Construct type wells (a.k.a. type curves) using both empirical and model-based techniques.
- Predict and evaluate the influence of interference in infill or "parent-child" well interactions.
Concepts covered in this course are:
- Basic fluid flow theory
- Transient flow
- Radial and linear flow
- Constant rate and constant BHP production
- Radius of investigation
- Boundary-dominated flow
- Empirical production decline methods of forecasting production and estimating Reserves in Unconventional reservoirs
- Arps decline model
- Minimum terminal decline methodology
- A priori determination of Arps decline parameter “b”
- Advanced decline curve analysis and its limitations
- Stretched exponential model
- Blasingame modified power-law model
- Long-duration linear flow model. Duong model
- Comparison of models and recommended workflow
- Use of analytical reservoir models in forecasting production and estimating Reserves in Unconventional reservoirs
- Use of statistical resource analysis in estimating Reserves in Unconventional reservoirs
- Applications of appropriate methodology to example situations
Who should attend
This Skilled Application level course is designed for mid to senior level engineers, geoscientists, and decision makers and engineering managers with interests in unconventional reservoir evaluation.

Background
John Lee served as an Academic Engineering Fellow with the U.S. Securities & Exchange Commission (SEC) in Washington during 2007-8, and was a principal architect of the new SEC rules for reporting oil and gas reserves.
He worked for ExxonMobil, specializing in integrated reservoir studies, prior to joining the A&M faculty. He later was Regents Professor of Petroleum Engineering at Texas A&M. While at A&M, he also served as a consultant with S.A. Holditch & Associates, where he specialized in reservoir engineering aspects of unconventional gas resources.
John is the author of three textbooks published by SPE and has received numerous awards from SPE, including the Lucas Medal, the DeGolyer Distinguished Service Medal and Honorary Membership.
