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.

A friction reducer comprising a polysaccharide-graft-water-soluble polymer (polysaccharide-g-water-soluble polymer).
A wellbore treatment fluid, comprising:
- an aqueous base fluid;
- and
- a friction reducer, where the friction reducer comprises a polysaccharide-graft-water-soluble polymer (polysaccharide-g-water-soluble polymer);
- where an amount of the friction reducer in the wellbore treatment fluid is in a range of from about 0.01 to 10 wt. % (weight percent).
A method of using a wellbore treatment fluid, comprising:
- introducing the wellbore treatment fluid into the wellbore, the wellbore treatment fluid comprising an aqueous base fluid and a friction reducer, where the friction reducer comprises a polysaccharide-graft-water-soluble polymer (polysaccharide-g-water-soluble polymer);
- where an amount of the friction reducer in the wellbore treatment fluid is in a range of from about 0.01 to 10 wt. % (weight percent).
