SWL = 0.2 SWCR = 0.22 SOWCR = 0.2 KRO = 0.9 KRW = 1 SORW = 0.2 KRORW = 0.8 |
Saturation table end-point scaling (SWCR, SGCR, SOWCR, SOGCR, SWL)
SWCR - critical water saturation (that is the largest water saturation for which the water relative permeability is zero)
SOWCR - critical oil-in-water saturation (that is the largest oil saturation for which the oil relative permeability is zero in an oil-water system)
SWL - connate water saturation (that is the smallest water saturation in a water saturation function table)
Relative permeability end-point scaling (KRW, KRG, KRO, KRWR, KRGR, KRORG, KRORW)
KRW - relative permeability of water at maximum water saturation parameter
KRO - relative permeability of oil at maximum oil saturation parameter
KRWR - relative permeability of water at residual oil saturation (or residual gas saturation in a gas-water run) parameter
KRORW - relative permeability of oil at critical water saturation parameter

SGCR = 0.05 SOGCR = 0.4 KRORG = 0.7 KRGR = 0.8 KRG = 0.9 |
Saturation table end-point scaling (SWCR, SGCR, SOWCR, SOGCR, SWL)
SGCR - critical gas saturation (that is the largest gas saturation for which the gas relative permeability is zero)
SOGCR - critical oil-in-gas saturation (that is the largest oil saturation for which the oil relative permeability is zero in an oil-gas-connate water system)
Relative permeability end-point scaling (KRW, KRG, KRO, KRWR, KRGR, KRORG, KRORW)
KRG - relative permeability of gas at maximum gas saturation parameter
KRGR - relative permeability of gas at residual oil saturation (or critical water saturation in a gas-water run) parameter
KRORG - relative permeability of oil at critical gas saturation parameter
