This paper compares the output of several available empirical black oil model correlations against compositional model results. In this process, the limitations of these models became apparent.

Even acknowledging the imperfections of black model implementation, it is possible to improve the quality of the outputs by means of making the definitions consistent and coherent across the prediction ranges.

A new method is outlined in order to extend the validity of the models in predicting both reservoir and multiphase flow simulations.

This new method is presented here and will be extended in a separated paper.
