Polymers for mobility control in enhanced oil recovery
This report focuses on the FY-89 results of a fundamental research program underway in the Polymer Science Laboratories at the University of Southern Mississippi to develop novel associative polymers which should be significantly more efficient than those presently used in Enhanced Oil Recovery processes. These new systems rely on cooperative hydrophobic associations to yield appropriate rheological behavior. We hope to ultimately develop, with the help of appropriate rheological behavior. We hope to ultimately develop, with the help of industry, simple copolymer systems which could be easily utilized by independent oil operators in mobility control processes. Research has focused on preparation, characterization and rheological study of copolymers possessing intra- or intermolecular associations. Associative copolymers of acrylamide with N-alklacrylamides; terpolymers of acrylamide, N-decylacrylamide, and NaAMPS, NaA, or NaAMB; and copolymers of acrylamide with the zwitterionic AMPDAPS monomer have been shown to possess rheological behavior of potential in EOR processes. The salt-induced conformational responses and resulting association mechanisms are being studied by a number of techniques including rheometry, gel permeation chromatography, quasielastic light scattering, and fluorescence spectroscopy. 114 refs., 50 figs., 18 tabs.
