Mathematical models of relative permeability.

The usual practice is to build 2-phase RPM based on SCAL data and then use 3-phase RPM correlations (see table below).

In case the 2-phase SCAL data is insufficient or highly scattered one can use 2-phase RPM correlations (see table below), calibrated to whatever SCAL and production data available.
