A core sample from a subterranean reservoir is placed in a pressure cell holder and the core pressure is measured at a plurality of pressure points along the core before and during fluid flooding. A computed tomography (CT) scanning system provides images of the density distribution within the core sample during such waterflooding. Fluid saturation, determined from these CT images, and pressure gradients, determined from the pressure measurements are used to determine the relative permeability of the subterranean reservoir.
