Influence of pore geometry on water- oil relative permeability

Abstract

The interrelationship of pore geometry, rock properties, and wateroil relative permeability is illustrated with photomicrographs and relative permeability curves of reservoir rocks. Data are shown to be very similar within a given rock type, emphasizing the need to determine the various reservoir rock types and their distribution. Some effects of core handling are discussed. An example of calculated vs observed waterflood performance is shown, and a data collecting procedure is recommended.
