A new approach in correlating the oil thermodynamic properties

A new compositional model is proposed to improve the prediction of phase be havior and physical properties of oil reservoir effluents. This work is bas ed on a very classical and easy-to-handle cubic equation of state (EoS) cou pled with a performing group contribution method devoted to the estimation of binary interaction parameters. The proposed model is compared to other p ublished methods on the basis of laboratory data on real fluids, including pressure/volume/temperature (PVT) measurements and slim tube experiments. T he method developed in this work shows enhanced results on a large range of pressure and temperature. (C) 2001 Published by Elsevier Science B.V.
