Water cut - Stiles
Input(s)
k: Permeability (mD)
h: Cumulative Thickness for Breakthrough Layer & Above (ft)
\(M_{w o}\): Mobility Ratio (fraction)
\(k_{t}\): Cumulative Flow Capacity for Breakthrough Layer & Above \((\mathrm{mD} \mathrm{ft})\)
\(h_{t}\): Cumulative Flow Capacity for the Whole Model \((\mathrm{mD} \mathrm{ft})\)
Output(s)
\(f_{w}\): Water Cut (fraction)
Formula(s)
\[
f_{w}=\frac{k * h * M_{w o}}{k * h * M_{w o}+k_{t} * h_{t}-k * h}
\]
