In mature, oil-producing reservoirs, conditions like natural fissions in the reservoir rock or resistance from heavier or more viscous oils require enhanced oil recovery (EOR) injection techniques. Polymer flooding is one EOR technique that is widely used because it can significantly improve oil recovery over conventional flooding. It uses polymer solutions in an aqueous medium to increase oil recovery by reducing the water-to-oil mobility ratio. Managing the viscosity of the EOR polymers at the well head supports efficient oil production, while helping to reduce the amount of EOR polymer needed.
