Book excerpt: 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% CaCl2 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 tends to impart increased shear sensitivity. Degree of hydrolysis also affects performance of the modified polymer. 25 figures, 40 tables.

Book excerpt: The objective of this laboratory work is to develop improved mobility control agents that are more effective than the commercial polymers currently used in this process. During the second year of the project, the baseline testing of commercial products was completed. These baseline tests with polymers include studies on mobility control, retention, and shear degradation in Berea cores, the effect of common ions on rheological properties, thermal stability, microbial degradation, and surfactant-polymer interactions. These data are used for comparison of the commercial agents at standardized sets of conditions, and are also used to evaluate new, modified, or improved polymers. Work was also initiated on the synthesis, characterization, and preliminary screening of new and modified polymers. Testing of these analogs provides systematic correlations of polymer performance with polymer structure. This preliminary testing consists of measurements of shear degradation and viscosity loss in NaCl brines by the use of a simplified screening procedure. To date, a number of potential structure-utility relationships have been observed. Solution viscosities of all nonionic polymers tested are essentially insensitive to changes in NaCl concentration. Increasing the charge-to-mass ratio (degree of hydrolysis) of either polyacrylamides or N-alkyl analogs enhances the ability of these polymers to build viscosity in low salinity NaCl brines. However, such polymers are increasingly subject to viscosity loss as the salinity is increased. Above a certain critical molecular weight, polymers become more susceptible to shear degradation. Many of the polymers that possess stiffer backbones exhibit improved brine and shear stability. The results of these studies will be used to develop an improved mobility control polymer in the next phase of this project.

Available in PDF, EPUB and Kindle. Book excerpt: During the first year, the initial phase of the project included a literature survey of surfactant/polymer flooding, a summary of the current status of DOE-sponsored polymer and surfactant/polymer field projects, and a survey of oil industry personnel regarding difficulties encountered in the use of commercially available polymers. Major problems in the use of partially hydrolyzed polyacrylamides were identified. Purpose of Phase 1 was to delineate the strengths and weaknesses of commercial polymers. Laboratory tests in the second phase then were designed to measure and compare the factors considered to be of greatest importance. During the second year of the project, the Phase 2 baseline screening tests were completed, and Phase 3 work commenced on the synthesis, characterization, and preliminary screening of new or modified polymers. During the final year of the project, the preliminary screening tests were completed and polymers of interest were evaluated in more detail. This final report contains highlights of the significant accomplishments of the project and presents our conclusions regarding the development of improved mobility control agents. The work has shown that moderate changes in the basic structure of acrylamide polymers can produce significant effects on performance in oil recovery applications. Better viscosity retention in brine can be obtained by stiffening the polymer chain of acrylamide-type materials. Enhanced shear stability can be attained by increasing the polymer hydrophilicity.
