Mobility control in oil recovery by chemical flooding (polymer, micellar-polymer, and alkaline-polymer) can be achieved through the use of low-concentration water-soluble polymers in water or in chemical slugs. Since the late 1950's, water-soluble polymers have been studied extensively in laboratories by many researchers and widely used in many chemical flooding projects to improve sweep efficiency and increase ultimate oil recovery. Effective use of polymers as mobility control agents requires the understanding of the stability of polymers and their rheological behavior in reservoirs. An overview of the scientific literature on the application of water-soluble polymers in enhanced oil recovery (EOR) is presented. The processes, factors, and mechanisms that influence the stability of polymers and those that cause a reduction in water mobility are discussed. Existing knowledge of polymer flow behavior in porous media, and of surfactant-polymer interactions is reviewed. Also discussed are the case histories of 23 chemical flooding field projects. 177 refs., 6 figs., 5 tabs.
