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_f -\phi_{f0})^3}{( 1 - \phi_f+\phi_{f0})^2} |
where
\phi_f | fracture porosity |
\phi_{f0} | fracture porositycut-off |
D_f | proppant grain size |
\tau_f | fracture pore channel tortuosity |
