The development of a multiphase, multicomponent thermal simulator requires careful consideration of several aspects of the problem. In this paper, one important aspect associated with the development of a compositional thermal simulator is discussed. This is the problem of disappearance and appearance of phases. New pseudo-equilibrium ratios are introduced to allow the use of one formulation regardless of the phases present. This approach handles the appearance and disappearance of oil, water and gas phases in an extremely simple fashion.
