Well Testing: Interpretation Methods

Useful as both a text and a reference, this volume will greatly help practicing engineers and technicians to interpret well testing. It places emphasis on the most suitable interpretation methods for each case dealt with: traditional methods, standard type graphs, computer assisted graph generation, interpretation with the help of derivatives. The text presents all equations necessary for the interpretation while avoiding lengthy mathematical developments. Finally, the large number of references allows to trace the solutions back to their sources. The scope and field of application of these methods are developed, with many practical examples and a large number of illustrations. The book shows how an interpretation of well testing varies according to the type of reservoir limits (faults, channels, secant faults, constant pressure limits, closed reservoirs) and the well reservoir configurations (partial penetration wells, inclined wells, artificially fractured wells, horizontal wells, injection wells). It also treats the case of more complex reservoirs (fissured reservoirs, two-layered reservoirs). The methods to be used when the fluid contained in a well is a gas or a polyphasic fluid are described in detail. Lastly, it describes interference and pulse tests, involving several wells at a time.
