Performance Forecasting in Shale Reservoirs

The “Performance Forecasting in Shale” book provides an overview of methods for forecasting production in shale oil and gas reservoirs. It examines physics-based analytical models, empirical correlations, numerical simulation, and hybrid approaches. Moreover, the text explains how to integrate data from geology, petrophysics, completion design, and initial performance to calibrate predictive models. Detailed field applications demonstrate probabilistic forecasting workflows to quantify uncertainty in shale well productivity and recovery. Furthermore, case studies illustrate use of predictive models to optimize completion strategies, well spacing, and development planning in shale assets. Overall, the book serves as a valuable reference on leveraging predictive modeling to de-risk shale development and maximize recovery.

The purpose of this collection of papers in the “Performance Forecasting in Shale Reservoirs” book is to introduce the subject of performance forecasting in shale reservoirs to engineers interested in gaining a basic overview of the technology and its applications. It is intended not to offer a comprehensive look at the topic but, rather, to provide the reader with enough knowledge to allow for more advanced study or work in the field. Topics covered include: Understanding Performance With Numerical Models • Performance Predictions With Analytical/Empirical Methods • Assessing Uncertainty and Recovery Estimation.
