Abstract

Disclosed is a gel composition comprising an acrylamide polymer or copolymer crosslinked with a dialdehyde (e.g. glyoxal, malondialdehyde, succindialdehyde, glutaraldehyde, adipaldehyde, ophthaldehyde, m-phthaldehyde or p-phthaldehyde) wherein the gel composition is formed by combining the acrylamide polymer or copolymer and dialdehyde in an aqueous solution at a pH in the range of about 9.0 to about 11, and wherein the acrylamide polymer or copolymer has a charge between about 15 to about 35 mole %, and wherein the molar ratio of dialdehyde to monomers of the acrylamide polymer or copolymer is in the range of about greater than about 1.1 to about 2.0. Further disclosed is a wellbore treatment fluid comprising the gel composition as defined above, and optionally further including a natural or synthetic proppant, selected from glass beads, ceramic beads, sand, gravel, and bauxite or combinations thereof. Also disclosed is a method of treating a wellbore comprising injecting a composition comprising an acrylamide polymer or copolymer into a wellbore; injecting a composition comprising dialdehyde into the wellbore, and injecting a pH modifying agent into the wellbore in an amount sufficient to produce a downhole solution pH in the range of about 9.0 to about 11, to produce an in-situ gel composition comprising an acrylamide polymer or copolymer crosslinked with dialdehyde; and wherein the acrylamide polymer or copolymer has a charge between about 15 to about 35 mole %, and wherein the molar ratio of dialdehyde to monomers of the acrylamide polymer or copolymer is in the range of about greater than about 1.1 to about 2.0.
