A method of servicing a wellbore penetrating a subterranean formation, comprising:
- placing into the wellbore a wellbore servicing fluid comprising a superabsorbent starch hydrogel (SSH) and an aqueous fluid, wherein the SSH is formed from an SSH reaction mixture comprising a starch, a crosslinker, a base, and water;
- wherein the starch is present in the SSH reaction mixture in an amount of from about 1 wt. % to about 15 wt. %, based on a total weight of the SSH reaction mixture;
- wherein a weight ratio of the starch to the crosslinker present in the SSH reaction mixture is in a range of from about 0.4 to about 20;
- and wherein the wellbore servicing fluid is thixotropic.
