The hydrolysis of polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers at elevated temperatures was noted by Muller et al., (1980, 1981a, 1981b) and Shupe (1981) due to the increase of viscosity, change in pH, and evolution of ammonia observed in PAM solutions aged at elevated temperature, as well as precipitation
Abstract There are many oil reservoirs worldwide with substantial amount of H 2 S but otherwise very favorable conditions for polymer flooding such as low temperature, high permeability, and moderate to high oil viscosity. However, there is a legitimate concern about the chemical stability of polymers when there is dissolved oxygen in the injection water or injection facility and its high
