EXAMPLE #$2$

A core sample from a uniform sandstone formation has a permeability of $480mD$ and a porosity of $0\mathrm{.}17.$

Estimate:

$($a$)$ the average pore throat radius of the core;

$($b$)$ specific surface areas $s_{V{p}_p}$ and $s_{Vgr}.$

$1mD=9\mathrm{.}8717{10}^{-4}{m}^2$

$m={10}^{-6}m={10}^{-4}cm$

$($a$)4\mathrm{.}7{10}^{-4}cm$

$($b$)4,\frac{2351}{c}m,\frac{8671}{c}m$
