We study wettability in porous media by using micromodels (microfluidics) and -CT. We are characterizing multiphase flow in various wetting states and relations to trapping. We are working on establishing experimental support for the ensemble probability distribution by microscantomography of flow in rocks. The focus is to understand oil trapping in channels and pores at different conditions. The evolution of wettability together with the distribution of oil and water versus time will be monitored. The learning from these fundamental and simplified experiments will be extended to two phase flow experiments in complex micromodels. This approach will provide insight on both local and global dynamic wettability evolution.
