Description

The 'kr3p_StoneII_SwSg()' creates a table of three-phase oil relative permeability data for water, gas, and oil saturation values between zero and one. This model reads the water, and gas saturation values in the three-phase region as water, and gas saturation inputs into two-phase relative permeability models

SOIRW

irreducible oil saturation, fraction

SORW

residual oil saturation, fraction

SOIRG

irreducible oil saturation, fraction

SORG

residual oil saturation, fraction

SGCON

connate gas saturation, fraction

SGCRIT

critical gas saturation, fraction

KRWIRO

water relative permeability at irreducible oil

KROCW

oil relative permeability at connate water

KRGCL

gas relative permeability at connate liquid

NW

exponent term for calculating krw

NOW

exponent term for calculating krow

NG
