Abstract:
1. A method of treating a subterranean formation, comprising: providing a treatment fluid comprising: an aqueous fluid; a gelling agent; and a multifunctional boronic crosslinker comprising a dendritic polymer and two or more boronic functional groups, wherein the dendritic polymer comprises at least one monomer unit selected from the group consisting of an acrylamide, a 2-acrylamido-2-methyl propane sulfonic acid, a N,N-dimethylacrylamide, a vinyl pyrrolidone, a dimethylaminoethyl methacrylate, an acrylic acid, a dimethylaminopropylmethacrylamide, a vinyl amine, a vinyl acetate, a trimethylammoniumethyl methacrylate chloride, a methacrylamide, a hydroxyethyl acrylate, a vinyl sulfonic acid, a vinyl phosphonic acid, a vinylbenzene sulfonic acid, a methacrylic acid, a vinyl caprolactam, a N-vinylformamide, a diallyl amine, a N,N-diallylacetamide, a dimethyldiallyl ammonium halide, an itaconic acid, a styrene sulfonic acid, a methacrylamidoethyltrimethyl ammonium halide, a quaternary salt derivative of acrylamide, a quaternary salt derivative of acrylic acid, an alkyl acrylate, an alkyl methacrylate, an alkyl acrylamide, an alkyl methacrylamide alkyl dimethylammoniumethyl methacrylate halide, an alkyl dimethylammoniumpropyl methacrylamide halide, any derivative thereof, and any combination thereof; and introducing the viscosified fluid into a subterranean formation.
