Description

Calculate three-phase oil relative permeability using Stone I and Stone II models. These models combine two-phase water-oil and gas-oil data to predict oil mobility when all three phases are present.

Key Differences:

  • Stone I: Requires minimum oil saturation (Som) parameter
  • Stone II: Self-predicting - no Som required, uses water and gas rel perm directly

Assumptions:

  • Krw in three-phase = Krw from two-phase water-oil system
  • Krg in three-phase = Krg from two-phase gas-oil system
  • Only Kro is modified by three-phase interactions
