Precise and accurate characterization of reservoir fluid is a very important factor in reservoir simulation studies. PVT experiments are usually expensive and performed in limited conditions. Therefore, EOS based PVT packages are widely used for the prediction and evaluation of fluid properties over a wide range of temperature, pressure and composition. Because widely used commercial packages executed in DOS environment are not oriented towards users, we developed user-friendly phase behavior model utilizing the object-oriented language, Visual C++. This model is composed mainly of multiple stage separation module, phase envelope generation module, and experimental simulation module including CVD, CCE, DL, swelling test scheme. In order to investigate the validity and applicability of developed model, different equation of states were analysed for the prediction of fluid properties using reservoir fluid data. Good agreement was obtained between published and calculated results by this model.
