WebNov 4, 2015 · Φ is porosity in percent. A log ( k )- Φ plot based on Eq. 4 and showing five characteristic lines for pore throat radius is shown in Fig. 2. Note that at a given porosity, permeability increases roughly as the square of the pore throat radius. And for a given throat size, the dependence of permeability on porosity is slightly less than Φ2.
