PO.SCAL.LET.Krow Function
Description:
Calculates LET-type oil relative permeability, [dimensionless].
Excel Function Syntax:
=PO.SCAL.LET.Krow(Sw, Swi, Sorw, Krow_Swi, Lo, Eo, To)
Parameters:
| Parameter | Description |
|---|---|
| Sw | Water saturation, [fraction]. |
| Swi | Irreducible (minimal) water saturation, [fraction]. |
| Sorw | Residual (minimal) oil saturation after water flooding, [fraction]. |
| Krow_Swi | End point of oil relative permeability, usually equals 1, [dimensionless]. |
| Lo | Empirical constant describes the lower part of the curve, [dimensionless]. |
| Eo | Parameter E describes the position of the slope (or the elevation) of the curve, [dimensionless]. |
| To | Empirical constant describes the upper part of the curve, [dimensionless]. |

LET Relative Permeability Curves
Generate oil-water relative permeability curves using the LET (Lomeland-Ebeltoft-Thomas) correlation. This model offers more flexibility than Corey for matching laboratory data.
Relative Permeability Model Comparison
Compare relative permeability predictions from Corey, LET, and Honarpour correlations. Model selection affects waterflood performance predictions.
