ABSTRACT:
A porous rock is saturated with a first fluid and electrical resistivity is measured along its length. A second fluid, immiscible with the first fluid, is injected into the porous rock at a first flow rate. This injection continues until displacement of the first fluid from the porous rock ceases and the pressure drop along the porous rock becomes constant, indicating a first residual fluid saturation equilibrium. The foregoing is repeated for a plurality of increasing second fluid injection flow rates to effect electrical resistivity measurements at decreasing residual fluid saturation equilibriums. The method may then be repeated substituting the second fluid for the first and vice versa to perform an imbibition experiment.
