Abstract
A core sample of a porous rock from a subterranean reservoir is placed in a pressure cell holder. The sample is desaturated to first fluid irreducible desaturation with a second fluid through a porous plate preferentially wet to only the first fluid. The sample is then flooded with a plurality of first and second fluid ratios. Core pressure is measured along the core at various differential pressure plateau's during initial first fluid desaturation and again during fluid flooding with first and second fluids. A computed tomography (CT) scanning system provides images of the density distribution within the core sample during such flooding. Fluid saturation, determined from these CT images, and the pressure measurements are used to determine the relative permeability and capillary pressure responses of the fluids within the subterranean reservoir.
