Capacity ratio of a hydraulically fractured surface
Input(s)
\(k_{f}\): Fracture Permeability \((\mathrm{mD})\)
\(k\) : Average Formation Permeability \((\mathrm{mD})\)
\(h\) : Formation Thickness (ft)
\(W\) : Fracture Thickness (ft)
Output(s)
\(c_{f}\): Cumulative Present Value of Production ($)
Formula(s)
\[
c_{f}=\frac{k_{f} \cdot W}{k \cdot h}
\]
