  • Systems and methods for performing a polymer flood having a graded polymer concentration
    Patent number: 12618312
    Abstract: A method for performing a polymer flood of a hydrocarbon-bearing, subterranean reservoir. The method includes injecting a polymer solution from an injection well (32) into the subterranean reservoir to form a polymer slug in the subterranean reservoir, wherein the polymer slug has a leading front and a trailing rear (48), and a graded viscosity profile which decreases in viscosity from the front of the polymer slug to the rear of the polymer slug. The method additionally includes injecting an aqueous solution (50) from the injection well into the subterranean reservoir following to displace the polymer slug through the subterranean reservoir.

  • SYSTEMS AND METHODS FOR PERFORMING A POLYMER FLOOD HAVING A GRADED POLYMER CONCENTRATION
    Publication number: 20250052140
    Abstract: A method for performing a polymer flood of a hydrocarbon-bearing, subterranean reservoir (5) includes (a) injecting a polymer solution from an injection well (32) into the subterranean reservoir to form a polymer slug (44) in the subterranean reservoir, wherein the polymer slug has a leading front (46) and a trailing rear (48), and an S-shaped graded viscosity profile which decreases convexly in viscosity from the front of the polymer slug to an inflection point and concavely in viscosity from the inflection point to the rear of the polymer slug, (b) injecting an aqueous solution (50) from the injection well into the subterranean reservoir following (a) to displace the polymer slug through the subterranean reservoir.
