This research applied multiphase pseudopressure and pseudotime concepts with appliying semi-analytical single phase solution for analysizing of transient-pressure of multiphase oil-gas flow. <br /> The pseudopressure and pseudotime concepts involves parameters of multiphase flow properties such as relative permeabilities and reservoir fluids into the two pseudo parameters that could reduce non linearities <br /> embedding in the multiphase diffusivity equation. The aim of this study is to examine application of the pseudopressure and pseudotime <br /> concepts in analysizing of transient pressure of two phase oil-gas flow with a flow rate constant. <br /> This study uses two dimensional, radial reservoir simulation model. That yields bottom hole transient pressure profiles using <br /> hypothetical data. In addition, effects of wellbore damage and wellbore storage on the build-up data were also studied. The results indicate that for low absolute permeabilities (50 <br /> md) the proposed method can reduce the error up to 10_554 % over the conventional method, and for high permeability (300 md) can reduce the <br /> error up to 6.004 % over the conventional method.
