In this paper, we present a case history of integrating mumerical and analytical well test analysis methods to interpret the pressure and production history of a complex, multilayer, multiphase reservoir. Some engineers believe that recent improvements in analytical models have made numerical modeling for well test interpretation all but obsolete. Others believe just as strongly that numerical models should be used for routine well test interpretation. Still others believe that both tools are useful, and that a combination of the two approaches provides the best general strategy for reservoir charactrization. This field case focuses on the Gas Research Institute(GR) Staged Field Experiment(SFE) No.2. This well was hydraulically fracturd. A variety of different analysis techniques were applied in order to evaluate the consistency between reservoir and fracture properties estimated by the different methods of analysis.
