The geochemical parameters investigated in this project are: rock mineralogy (Austin chalk, Indiana limestone, Silurian dolomite, and Berea sandstone), aqueous chemistry (pH and salinity), oil chemistry and temperature. If the effects of the proposed parameters are examined with respect to each other, an overwhelming number of experiments would be required. Therefore, conventional experimental studies such as contact angle measurements and flow through porous media experiments cannot be used to study all the parameters in the allocated time for this project. This paper will present an alternative method of estimating wettability that is much faster and has high repeatability, and thus creates a well-informed screening tool to sort through different possible chemical conditions present in the reservoir and pick the parameters of interest for further study.
