WebNov 19, 2024 · Summary. Darcy’s law connects the gradient of pressure and flow velocity in rocks via their permeability κ. Depending on flow velocity, pressure and matrix properties, there are law corrections after Forchheimer, Brinkman and Klinkenberg. Rock permeability depends on ambient pressure, temperature and deviatoric stresses.
