%X Variations of fluid saturation in formation induce unusual trends in pressure transient data, which may cause ambiguities in well test interpretations. Nevertheless, uniform saturation distribution is a common assumption applied in all multiphase well test analysis methods and the effects of fluids saturation changes have not been taken into account in all these approaches. We present a theoretical model which includes non-uniform fluid saturation in pressure transient formulation. The application of the developed model is demonstrated using a simulation of a reservoir containing non-uniform oil and water saturations in the initial condition. This model provides a basis for better interpretation of unusual pressure transient behavior affected by non-uniform saturation distribution.
