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)

$$ J=\frac{P c}{\sigma * \cos (\theta)} *\left(\frac{k}{\varnothing}\right)^{0.5} $$
