kr2p_ow.RdThe 'kr2p_ow()' creates a table of two-phase water and oil relative permeability data for water and oil saturation values between zero and one.
kr2p_ow(SWCON, SWCRIT, SOIRW, SORW, KRWIRO, KROCW, NW, NOW, NP)
| SWCON | connate water saturation, fraction |
|---|---|
| SWCRIT | critical water saturation, fraction |
| SOIRW | irreducible oil saturation, fraction |
| SORW | residual oil saturation, fraction |
| KRWIRO | water relative permeability at irreducible oil |
| KROCW | oil relative permeability at connate water |
| NW | exponent term for calculating krw |
| NOW | exponent term for calculating krow |
| NP | number of saturation points in the table, the maximum acceptable value is 501 |
A matrix with water saturation, oil saturation, water relative permeability, and oil relative permeability values, respectively
