Relative Permeability Hysteresis Drainage: Capillary and viscous forces operate in the same direction. Imbibition: Capillary and viscous forces operate in opposite directions, resulting in a portion of the non-wetting phase becoming trapped and unable to move.

Calculation of Non-wetting Phase Relative Permeability (Land) Basis: Correct for amount of “trapped” phase. Use resulting “free” saturation for the calculations. Equations written for a gas-water two- phase system, gas is non-wetting phase. Applies oil-water system if it is strongly water-wet.
