Abstract: A compositional reservoir simulator using a sequential formulation of the fluid flow and phase equilibrium equations requires that the phase equilibrium and associated derivatives of the dependent phase equilibrium variables with respect to the pressure and moles of individual components be computed every time step for all the grid blocks in the system. The phase equilibrium calculations are computation intensive, since they solve a nonlinear system of equations and are thus iterative in nature. This paper describes techniques for implementing the phase equilibrium and the associated derivative calculations in a sequential compositional reservoir simulator designed for large reservoir models.
