The pressure transient test is one of the more important tools for evaluating reservoir performance. By measuring the change of pressure over time, pressure transient information is obtained. The method entails measuring flow rates and pressures under a range of flowing conditions and applying the data to a mathematical model. Fundamental data relating to the interval under test, such as reservoir height and details of the reservoir fluids, are also part of the input.
In many cases, wells and reservoirs were managed according to the data based on pressure transient tests. However, as the quality of information obtained from a pressure transient test depends, among other things, on the quality of the pressure and flow data, it is imperative to prevent inaccuracy in the pressure and flow measurements to assure integrity of data. At present, conventional pressure transient testing methods have been adapted in the petroleum industry. These methods provide useful general indicators of reservoir permeability, the flow capacity of the reservoir and any damage that may be restricting productivity.
