An interactive computer model has been developed using thermodynamic properties evaluated by the optimal selection of Peng-Robinson (PR) or Modified Soave-Redlich-Kwong (MSRK) equations of state for high pressure multicomponent, hydrocarbon phase equilibrium calculations. Evaluation of the thermodynamic properties using the PR or MSRK equations of state requires input data of critical pressure, critical temperatures, and acentric factor for each component. A procedure is developed for evaluating this data for petroleum fractions such that the equation of state matches experimental reservoir fluid phase behavior. The developed phase behavior algorithm is tested on a wide range of reservoir fluids including gas condensates and volatile oils. The phase behavior model is applied successfully to predicting the depletion performance of a gas condensate reservoir. 20 references.
