    2018-3-22 · Adding a small concentration of polymer to water will significantly increase the viscosity of the water (Nouri & Root, 1971). The polymers most commonly used as mobility control agents include synthetic polymers (e.g., hydrolyzed polyacrylamide), biopolymers (e.g., xanthan), and, recently, associative polymer.
