Transient testing is facing a challenge to have the information it provides incorporated in numerical simulators used to predict reservoir performance. The main reason for the problem is that transient testing technology, developed largely via analytical solutions, provides average reservoir parameters not suited to the numerically discretized environment of current reservoir simulators. Previous efforts to include transient testing data in numerical reservoir simulation studies focused on history matching the pressure behavior during the test on a Cartesian-type plot just like matching stabilized production rates and pressures. Such approach neglects the wealth of information contained in the transient behavior of the tests.A method called Numerical Well Testing (NWT) is proposed in this talk to preserve the information obtainable from traditional well test analysis and deliver it in a form suitable for direct use in numerical reservoir simulation. NWT is a systematic method that consists of five steps starting with traditional well test analysis, locally refining grids based on the analysis results, modifying full field numerical models, upscaling the results, and predicting future reservoir performance. Two field examples are used to illustrate the method. The talk concludes by describing the software developments needed to make NWT a routine analysis method.Bio - Medhat M.
