Leverett J-function

（重定向自Leverett J function）

In petroleum engineering, the Leverett J-function is a dimensionless function of water saturation describing the capillary pressure,

where $S_w$ is the water saturation measured as a fraction, $p_c$ is the capillary pressure (in pascal), $k$ is the permeability (measured in m²), $\phi$ is the porosity (0-1), $\gamma$ is the surface tension (in N/m) and $\theta$ is the contact angle. The function is important in that it is constant for a given saturation within a reservoir, thus relating reservoir properties for neighboring beds.
