Abstract: The mechanisms by which hydrates deposit in a petroleum production-line are likely to be related to pipeline surface properties, e.g. pipeline material, surface energy and roughness. In this work, the wettability alteration of pipeline surfaces from contact with oil, as well as the adhesion energy between water and solid in the presence of oil is investigated. Contact angles are determined as a function of solid material and oil composition, for both model oils and crude oils. Although contact angles in oil/brine/solid systems have been extensively reported in the literature, the variety of solids that may mimic a pipeline is limited. In this study, we include various metal surfaces in addition to glass and a coating. Initial results from using near infrared imaging for collecting contact angle data in non-translucent systems are also presented.
