Tertiary Oil-Recovery-Processes Research at the University of Texas. Final Report (Branched Alkyl Benzene Sulfonates, Secondary Alkane Sulfonates, alpha -Olefin and Ethoxylated Alkane Sulfonates).

摘要

During the past year we have continued two major projects: (1) the design and evaluation of newly made surfactants and (2) the adsorptive behavior of surfactant systems. In addition to these ongoing projects, we have initiated a study on mobilization of oil droplets. In surfactant design and evaluation we have completed room temperature studies on branched alkyl benzene sulfonates, gotten well under way on secondary alkane sulfonates, and initiated studies on alpha -olefin and ethoxylated alkane sulfonates. In surfactant adsorption studies, we have (1) investigated the influence of alcohol cosolvents on the adsorption of sodium laurate on powders, (2) continued studies of adsorption from microemulsions, (3) continued studies on monomer/micellar equilibrium by ultrafiltration, and (4) measured adsorption from excess aqueous phases. Finally, the recently initiated mobilization studies are being done under both equilibrium and non-equilibrium conditions. 46 figures, 2 tables. (ERA citation 08:031179)
