Research is reported devoted to determining the need for and technical/economic feasibility of using energy resources' concepts for ultrafiltration and reverse osmosis for treating oil field fluids and for reclaiming chemicals. Most of the work performed in the past reporting period has been involved in running emulsions through ultrafiltration membranes to determine flux rates. While a stable, remixable emulsion could not always be formulated using any sort of surfactant when starting from scratch, it was found that fairly stable emulsions can be made by starting with a small amount of ''feed'' emulsion from another batch. That is, water and oil are alternatively added to a small amount of stable emulsion until the resulting emulsion is approximately 10 parts of new material to 1 part of the starting emulsion. The resulting emulsion is quite stable and can be remixed easily by simple shaking after it has separated. Formulations using the same materials without starting from a seeding emulsion produce only a small water-in-oil layer, if any emulsion at all. Preliminary rate data for the various emulsions are tabulated. (JRD)
