Water blockage agents using hydrolyzed canola protein hydrogels

摘要

Conformance fluids comprising a base fluid; and a canola protein-based hydrogel comprising a copolymer of a water-swellable polymeric material grafted onto a hydrolyzed canola protein backbone, wherein the canola protein-based hydrogel is present in the conformance fluid in an amount in the range of from about 1% to about 10% by weight of the conformance fluid.
