Calculation of fractional flow curve
Input(s)
\(\mu_{w}\): Water Viscosity \((\mathrm{cP})\)
\(k_{r w}\): Relative Permeability to Water (dimensionless)
\(k_{r o}\): Relative Permeability to Oil (dimensionless)
\(\mu_{o}\): Oil Viscosity \((\mathrm{cP})\)
Output(s)
\(f_{w}\): Fraction of Total Flowing Stream Composed of Water (dimensionless)
Formula(s)
\[
f_{w}=\frac{1}{1+\frac{\mu_{w} * k_{r o}}{k_{r w} * \mu_{o}}}
\]
