Patent ID: 8513167

Claim:
A method of preparing a wellbore servicing fluid comprising: forming an oxidized polysaccharide by contacting a polysaccharide composition with an oxidizing agent and oxidatively cleaving at least one chemical bond of the polysaccharide selected from the group consisting of a glycosidic linkage and a hydroxylated carbon-carbon bond, wherein the oxidizing agent comprises a material with the general formula Y.nH 2 O.mH 2 O 2 wherein Y is a salt, n is equal to or greater than zero and m is equal to or greater than 1; contacting the oxidized polysaccharide with a sulfonating agent to form a carboxylated sulfonated polysaccharide; and contacting the carboxylated sulfonated polysaccharide with a wellbore servicing fluid.
