Textbook in PDF format This book is a comprehensive overview of shale gas science and engineering, covering key facets such as the geological and geochemical characteristics of shale gas reservoirs, gas transport mechanisms in shale nanopores, mathematical models and case studies for gas production, and enhancing gas recovery methods. The author presents a systematic summarization of gas flow and production in shale gas reservoirs from micropore to macro-reservoir scale. The research methods encompass experiments, well-testing, numerical simulation, and mathematical derivation
