Open the CIPO recordAbstract From the Canadian patent
A method and apparatus are provided for measuring a parameter such as capillary pressure in porous media such as rock samples. The method comprises mounting a sample in a centrifuge such that different portions of the sample are spaced at different distances from the centrifuge axis rotating the sample about the axis, measuring a first parameter in the different portions of the sample and determining the value of a second parameter related to the force to which each portion is subjected due to rotation of the sample. In one embodiment the first parameter is relative saturation of the sample as measured by MRI techniques and the second parameter is capillary pressure.
