- W2259895912 abstract "Phase 1: Based on a literature survey and input solicited from industry, academic, and government sources, inadequacies of the currently used mobility control materials were assessed. Phase 2: Baseline screening of commercially available polymers began in January 1979. Rheological measurements and mobility control test in Berea cores have been completed on Dow Pusher 700, Betz Hi Vis, Nalco Nal-flo, Cyanamid 960S, Kelco Xanflood, and Abbott Xanthan Broth. Similar tests were completed for Pusher 500, Pusher 1000, Amoco Sweepaid 103, and Pfizer Flocon Biopolymer 1035. Shear degradation tests in Berea core plugs have been completed for one acrylamide-type polymer and one xanthan polymer in 0.3% NaCl. Similar tests in 3% NaCl plus 0.3% CaCl/sub 2/ are in progress. Viscosity and screen factor data have been collected for most of the commercially available polymers. Long-term thermal stability tests with one polyacrylamide polymer and one xanthan polymer have been initiated. Phase 3: The polymer synthesis phase of the program is in progress. A series of N-alkyl (N-methyl, N-isopropyl, and N-butyl) acrylamide homopolymers and copolymers with acrylic acid has been synthesized. Variations of the substituents on the acrylamide nitrogen atom did not substantially change the properties of the parent compound. Increasing the molecular weight more » tends to impart increased shear sensitivity. Degree of hydrolysis also affects performance of the modified polymer. 25 figures, 40 tables. « less" @default.
