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)

$$ f_{w}=\frac{k * h * M_{w o}}{k * h * M_{w o}+k_{t} * h_{t}-k * h} $$
