When an outflow performance simulator is used, it is recommended that a Correlation Comparison always be carried out. There is no universal rule for selecting the best flow correlation for a given application. Depending on the particular correlation, flow regimes are identified and specialized holdup and friction gradient calculations are applied for each flow regime. They are therefore more correctly termed two-phase flow correlations.

Thus flow correlations in common use consider liquid/gas interactions. The oil and water are lumped together as one equivalent fluid. This article details the most widely used correlations for the prediction of the Vertical Lift Performance. The primary purpose of a multiphase flow correlations is to predict the liquid holdup (and hence the flowing mixture density) and the frictional pressure gradient.
