A procedure for solving compositional model equations is described. The procedure is based on the Newton-Raphson iteration method. The equations and unknowns in the algorithm are ordered in such a way that different fluid property correlations can be accommodated readily. Three different correlations have been implemented with the method. These include simplified correlations as well as a Redlich-Kwong equation of state (EOS). The example problems considered are a conventional waterflood problem, displacement of oil by CO/sub 2/, and the displacement of a gas condensate by nitrogen. These examples illustrate the utility of the different fluid property correlations. The computing times reported are at least as low as for other methods that are specialized for a narrower class of problems.
