Synopsis

This book is designed to be a technical reference for engineers and technicians who interpret well tests. For each case examined, it describes the most suitable interpretation methods, such as traditional methods, type curves, computer-generated type curves, and interpretation using derivatives. It cites the equations used to interpret results, while avoiding detailed mathematical discussions. Nevertheless, as numerous references are provided, those who wish to can trace the solutions back to their origins. The book also indicates the conditions under which different methods are useful, and is illustrated with a large number of figures and practical examples. The text shows how the interpretation of a well test varies according to the type of reservoir limits (e.g., faults, channels, secant faults, constant pressure limits, closed reservoir, etc.), the well reservoir configuration (e.g., partial penetration wells, inclined wells, artificially fractured wells, horizontal wells, injection wells, etc.), and the nature of more complex reservoirs (fissured reservoirs, two-layered reservoirs). It indicates which methods to use when the fluid in a well is a gas or a polyphasic fluid. Lastly, it deals with tests applied to multiple wells, including interference tests and pulse tests.Contents: Principle: 1. Principles of well testing. 2. Wellbore storage. 3. Skin.

About this title

Synopsis

This text and reference places emphasis on the most suitable interpretation methods for each case: traditional methods, standard type graphs, computer assisted graph generation, interpretation with the help of derivatives. All necessary equations are presented for the interpretation while avoiding lengthy mathematical developments. The large number of references allows users to trace the solutions back to their sources. Bourdarot shows how 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 (particle penetration wells, inclined wells, artificially fractured wells, horizontal wells, injection wells). It also treats cases in more complex reservoirs (fissured reservoirs, two-layered reservoirs). Lastly, it describes interference and pulse test, involving several wells at a time. Partial Contents: Interpretation methods Reservoir boundaries Reservoir aspects Well aspects Fluid aspects Interferences.
