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.

Abstract: The present invention relates to a method for determining a non-oil volume of a rock sample comprising: receiving a rock sample; and receiving a non-oil zone in a NMR map using a T1T2 sequence, the non-oil zone being associated to non-oil in the map; Then determining a first NMR map of the received rock sample using a T1T2 sequence, and determining a volume of non oil in the received rock sample based on an integral in an integration zone of the firstNMR map. The integration zone of the first NMR map being determined based on the received non-oil zone, and a calibration_value.

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.
