Relative permeability - Corey exponents
Input(s)
\(k_{\text {roe }}\): Permeability at end point \((\mathrm{mD})\)
\(S_{w}\): Saturation of Water (fraction)
\(S_{\text {or }}\): Residual Water Saturation (fraction)
\(S_{w i}\): Initial Water Saturation (fraction)
\(N_{o}\): Corey Coefficient (fraction)
Output(s)
\(k_{r o}\): Relative Permeability at given Saturation (mD)
Formula(s)
\[
k_{r o}=k_{r o e} *\left(\frac{1-S_{w}-S_{o r}}{1-S_{w i}-S_{o r}}\right)^{N_{o}}
\]
