Abstract: PROCESS FOR OPTIMIZING THE PROPERTIES OF AQUEOUS POLYMER SOLUTIONS USED IN POLYMER FLOODING The invention relates to a process for optimizing the properties of aqueous polymer solutions used for polymer flooding which comprises treating the polymer solutions under turbulent flow conditions in dynamic fluid dispersing or pumping equipment such that the residence time of the polymer solution in this equipment is less than approximately 20 seconds and the pump energy used is from about 1 to about 15 watts/liter of solution processed. This process permits the optimization of flow properties important in polymer flooding which results in the improved efficiency of the polymer flooding process.
