Abstract
Surface areas of two synthetic and three natural consolidated porous samples were obtained by the orr low-pressure permeametry technique. The results suggest that the orr technique is a useful substitute for the low-temperature gas adsorption (bet) method for determining the surface area of rock samples. It was more rapid than the bet method, and the surface-area values obtained were larger but agreed better with bet values than values calculated from the kozeny-carman equation. Efforts were unsuccessful to demonstrate the influence of channel-size distribution on pressure-flow rate curves by means of experimental data and a parallel channel model.
