| Summary: | In this paper we develop a semi-analytical procedure to determine the absolute permeability of rocks from microtomographical images. We underscore all phenomenological assumptions and hypothesis, we also point out some misleadings in current literature. The methodology is applied to three samples of sandstone rocks. The method was able to predict the order of magnitude for the two samples that have available experimental values. For the sample that does not show experimental permeability value, the result agrees with the order of magnitude predicted by other methods. |
