NOTE: NUMPVT records must be read.

24.5 Relative Permeability and Capillary Pressure Tables

The following saturation-dependent data should be entered a total of
NROCK times - one set of records for each Rock region defined in Section 24,4.

1, Heading Up to 80 characters.

2 SAT1 KROW1 KRW1 KRG1 KROG1 PCOW1 PCGO1

SAT Phase saturation (fr). Set SAT1 = 0.0 and SATn = 1.0,
KROW Oil relative permeability for oil-water system (fr).
KRW Water relative permeability for oil-water system (fr).
KRG Gas relative permeability for gas-oil system (fr).
KROG Oil relative permeability for gas-oil system (fr).
PCOW Oil/water capillary pressure (psi).
PCGO Gas/oil capillary pressure (psi).
NOTE: SAT refers to the saturation of each particular
phase. For example, in a data line following SAT = 0.2 we
have
KROW Oil relative permeability at 20% oil saturation.
KRW Water relative permeability at 20% water saturation.
KRG Gas relative permeability at 20% gas saturation.
KROG Oil relative permeability at 20% liquid (water plus oil)
saturation.
PCOW Oil/water capillary pressure at 20% water saturation.
PCGO Gas/oil capillary pressure at 20% gas saturation.
NOTE: KROG is used only when a three-phase oil relative
permeability is calculated (ITHREE= 1 in Record 4 below).
