A time-tested classic, this volume presents a comprehensive study of the creation and analysis of transient pressure responses in wells. Basic principles are reviewed, and the applicability and limitations of the various techniques are critically discussed and illustrated with examples. With its detailed review of literature and extensive bibliography, this book serves as a useful guide and reference to engineers directly engaged in well pressure work. Chapter topics include pressure buildup analysis, determination of average reservoir pressure, multiple-rate flow test analysis, pressure analysis in injection wells, and effect of reservoir heterogeneities on pressure behavior.
