Leverett J-function
Input(s)
\(\sigma\): Fluid interfacial tension \(\left(\mathrm{dyn} / \mathrm{cm}^{2}\right)\)
\(\theta\): Angle of wettability (fraction)
Pc: Capillary Pressure \((\mathrm{dyn} / \mathrm{cm})\)
k: Permeability \((\mathrm{mD})\)
\(\emptyset\): Porosity (fraction)
Output(s)
\(\mathrm{J}\): Leverett J-function (dimensionless)
Formula(s)
\[
J=\frac{P c}{\sigma * \cos (\theta)} *\left(\frac{k}{\varnothing}\right)^{0.5}
\]
