WebApr 29, 2024 · Mechanism of polymer flooding. Polymer flooding improves oil recovery through a combined mechanism of mobility control, disproportionate permeability reduction and viscoelastic nature of the polymers. Mobility control. Mobility ratio is defined as the ratio of the mobility of the injectant (water) to the mobility of the displaced fluid (oil). Webpolymer flooding. 1. n. [Enhanced Oil Recovery] An enhanced oil recovery technique using water viscosified with soluble polymers. Viscosity is increased until the mobility of the injectant is less than that of the oil phase in place, so the mobility ratio is less than unity. This condition maximizes oil-recovery sweep efficiency, creating a ...
