Statement

We have established a novel experimental and image analysis methodology to measure the relative permeability and pore occupancy in a complex micro-porous carbonate. We have demonstrated this by conducting waterflood experiments on Estaillades limestone sample at a capillary number, Ca =7.3×10-6 and performing differential imaging to distinguish macro-pore space, explicitly resolvable in the image, and micro-porosity, together with fluid occupancy. During multiphase flow we could distinguish three types of fluid occupancy in the micro-pore space II: filled with oil, filled with brine, and partially-saturated with both brine and oil present. The micro-porosity contributed significantly to the total porosity: the fully brine-saturated portion of the pore space contributed to a large initial brine saturation after primary drainage.
