INFLUENCE OF MULTIFRACTAL SCALING OF PORE GEOMETRY ON PERMEABILITIES OF SEDIMENTARY-ROCKS

Scanning electron microscope pictures of thin sections of sedimentary rocks have been digitized, and their pore space geometry analysed using multifractal statistics. It is observed that such analysis can lead to characterization of different sedimentological environments. In particular it is shown that the information dimension D(1) of the multifractal spectrum of the pore space is correlated to air permeability values measured from the corresponding core samples.
