A new approach to predict thermodynamic properties of oil

A new compositional model is proposed to improve the prediction of phase behavior and physical properties of reservoir effluents. This work is based on a very classical and easy-to-handle cubic equation of state ( EoS ) coupled with a performing group contribution method devoted to the estimation of binary interaction parameters. The proposed model is compared to other published methods on the basis of laboratory data on real fluids, including pressure / volume / temperature (PVT). The method developed in this work shows enhanced results on a large range of pressure and temperature. The calculated properties by this new method is compared with other results and a good agreement has been noticed.
