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.

Abstract: A method for determining a relation between an initial saturation and a residual saturation in a first fluid in a porous sample, comprising the following steps saturating a porous sample with a second fluid; measuring a local volume of the second fluid in the porous sample; establishing a steady state profile of a saturation in the first fluid in the porous sample; generating a rise of a capillary ascension flow of the second fluid through the porous sample; during the capillary ascension flow, simultaneously measuring a local volume of the second fluid; and determining the relation between the initial saturation and the residual saturation based on the measured local volume.
