Abstract
The method comprises the following steps providing a porous sample containing a first fluid; establishing a steady state profile of a second fluid content in the porous sample by applying a first mechanical load, to create a plurality of regions having different second fluid contents in the porous sample; measuring, in each of the plurality of regions, a local saturation in the first fluid or/and in the second fluid; measuring, in each of the plurality of regions, a corresponding local electrical resistivity and/or conductivity; and determining a value of the representative parameter based on the corresponding values of local saturation and of local electrical conductivity and/or resistivity in each of the plurality of regions.
