Effective phase equilibrium calculation for equation of state compositional reservoir simulation

摘要

Field studies basedon compositional simulations require a huge number of phse equilibrium calculations resulting in costly computig times.The ost common method for reducing thecomputig time is tosimplify the fluid description by combining its components intoseveral pseudo-components.Themain drawback of such pseudoizationis the loss of detailed compositional information about the reservoir fluids.
