Gas Well Handbook deals exclusively with the theory and practice of gas well testing, including pressure transient analysis techniques, analytical methods required to interpret well behavior, evaluating reservoir quality, reservoir simulation, and production forecasts. A highly practical volume, this book is written for drilling engineers, well logging engineers, reservoir engineers, engineering students, geologists, and geophysicists. The author draws from his extensive experience in well testing, reservoir simulation, RVT analysis basics, and production operations from around the world, providing the reader with a thorough understanding of gas well testing methods and analysis. Emphasizing practical field application, over 100 field examples are presented to illustrate basic methods for analysis. Simple solutions to the diffusivity equation are discussed and their physical meanings examined.
