One frequent observation from conventional pressure transient test analysis is that field data match mathematical models derived for homogeneous systems. This observation suggests that pressure data as presently interpreted may not contain details concerning certain reservoir heterogeneities. On the other hand, tracer tests may be more sensitive to heterogeneous elements present in the reservoir because of the convective nature of the flow test. In this study we investigate a possible improvement of conventional pressure transient and tracer test analysis by integrating these two types well-testing methods using the nonlinear least square regression method. To achieve this goal, a correlation between permeability and dispersivity is used to couple the response of both tests. A multi fracture tracer test model was coupled with conventional, fractal, and double porosity pressure models using a commercial spreadsheet. The proposed method is tested using experimental well test and tracer test data obtained from a fractured reservoir model where fracture apertures and distributions were known. It has been observed that the match of multi-fracture tracer test model coupled with dual-porosity-slabs pressure transient model was better than the other combinations. Moreover, this combination described the physics of the experiments better than the others did. It has been also observed that both models showed a nearly unique match
