Description After a presentation of the various interpretation techniques proposed by all well test interpretation computer programs (straight line
methods, pressure curve analysis, pressure derivative method), the advantages and limitations of the different approaches are discussed.
With today's powerful graphic and computing facilities, the characteristic features of the many different types of wells and reservoirs
are magnified, and a large catalogue of theoretical solutions is required for the analysis of transient test responses. More accurate
and useful information is extracted from well tests.
The interpretation models are reviewed for well, reservoir and boundary conditions.
The models hypothesis and the influence of the different parameters are presented in detail. Application to field measurements is thoroughly
documented. The most recent complex interpretation models, combining different types of well and reservoir configurations, are discussed.
Other testing methods, such as multiple well and single well vertical interference tests, or drill stem tests are explained. The analysis
techniques are presented for oil wells, but also in the case of gas or multiphase reservoirs.
Several real field examples are discussed
to illustrate practical well test diagnosis and interpretation. The different factors complicating well test analysis are reviewed.
