Abstract
A method and device is disclosed for evaluating simultaneously, and with the same equipment, the electric resistivity and flow parameters of a porous medium, from experimental measurements obtained from at least one multi-flow type displacement experiment which has application in oil reservoir development. The method continuously measures as a function of time the differential pressure between two ends of a sample, the electric resistivity of the sample and, for each stabilization step, at least two values of a displaced fluid production volume are also measured. A continuous curve of the displaced fluid production volume, from which flow parameters are estimated by means of a numerical flow simulator, is then deduced therefrom.
