    Abstract: A friction reducer includes a polysaccharide-graft-water-soluble polymer is provided. A polysaccharide in an amount of from about 0.1 to 50% by weight (wt. %) may make up the polysaccharide-graft-water-soluble polymer. A wellbore treatment fluid is provided that includes an aqueous base fluid and the friction reducer in an amount up to about 10% of the wellbore treatment fluid. A method of using a wellbore treatment fluid includes the step of introducing the wellbore treatment fluid as previously provided into a wellbore.

    Abstract: Provided are water-soluble polymers that may include a water-soluble bipolymer, a water-soluble anionic terpolymer, and a water-soluble cationic terpolymer. The water-soluble polymers may include a reaction product of a first monomer that has a vinyl-containing group linked to a pendant carbohydrate moiety; a second monomer that has a vinyl group, a carbonyl group and a nitrogen; an anionic monomer in a water-soluble anionic terpolymer; and a cationic monomer in a water-soluble cationic terpolymer. Further provided are aqueous solutions that may include a water-soluble bipolymer, a water-soluble anionic terpolymer, and a water-soluble cationic terpolymer. Further provided are methods of use that may include introducing an aqueous solution into a formation such that the formation fractures, where the aqueous solution may include a water-soluble bipolymer, a water-soluble anionic terpolymer, and a water-soluble cationic terpolymer.
