  • Patent number: 5637796
    Abstract: The device is suited for taking measurements on more or less porous samples of geologic origin, for example physical parameters: wettability, capillary pressure, saturations, etc, in the presence of multiphase fluids that are displaced during drainage and imbibition operations. It comprises a modular cell whose length can be suited to that of a sample by adding tubular sections (24) of equal or different lengths that are interposed between two sleeves (1A, 1E). The containment cell is provided at its opposite ends with ends (13, 14) possibly fitted with semipermeable membranes, to which fluid lines (15, 16) are connected. Joining pieces (9) possibly provided with a control valve (10) can be fitted to all the sleeves (1A to 1E) for the connection of pressure detectors, gas injection means, etc. The device can be applied to optimization of hydrocarbon recovery in underground reservoirs.
