The common model of Hydraulic Fracture Permeability is based on Cozeny-Karman permeability @model:
(1) | k_f = \frac{D_f^2}{72 \cdot \tau^2} \cdot \frac{(\phi_{ef}-\phi_{ef0})^3}{( 1 - \phi_{ef}+\phi_{ef0})^2} |
where
\phi_{ef} | fracture porosity |
\phi_{ef0} | fracture porosity cut-off |
D_f | proppant grain size |
\tau_f | fracture pore channel tortuosity |
