Abstract

The magpore method determines the pore fabric of sediment samples by saturating the pore network with a magnetic fl uid, then using<br>anisotropy of magnetic susceptibility (AMS) measurements to defi ne the preferred orientations of pore long and short axes. The full 3-D<br>permeability anisotropy of the sample can be predicted from the results, particularly the anisotropy degree and directions of maximum<br>and minimum permeability. The reliability of the method has been confi rmed by comparing magpore data with directly-measured 3-D<br>permeability anisotropy on sets of test samples.
