Abstract
The major objectives of this work are: (1) extend the modified
Patel-Teja (MPT) equation of state proposed for aqueous
electrolyte systems (Zuo and Guo, 1991) to describe the
liquid-liquid and vapor-liquid-liquid equilibria of
hydrocarbon-water/brine systems through introducing an
unconventional mixing rule to the energy parameter "a", (2) apply
the revised MPT model (MPT2 model) to predict the effects of the
coexisting water/formation water phase on the high-pressure phase
behavior of reservoir oils/gas condensates, of which no
experimental data is available.The predicted results indicate that
the influence of the coexisting aqueous phase is not negligible.
