A method of treating a subterranean formation comprises forming a storable aqueous suspension comprising a carrier fluid, a superabsorbent polymer, a proppant the proppant being suspended in the carrier fluid as a substantially perfectly supported particulate; diluting the storable aqueous suspension in-line to a desired concentration; and introducing the diluted storable aqueous suspension into the subterranean formation. A sand control method is also disclosed.

1. A method of treating a subterranean formation, the method comprising: forming a storable aqueous suspension comprising a carrier fluid,a superabsorbent polymer, anda proppant, the proppant being suspended in the carrier fluid as a substantially perfectly supported particulate slurry;diluting the storable aqueous suspension in-line to a desired concentration; andintroducing the diluted storable aqueous suspension into the subterranean formation;wherein forming a storable aqueous suspension comprises combining the carrier fluid witha composite comprising the proppant and the superabsorbent polymer in an unhydrated form, the superabsorbent polymer being at least partially embedded in a void area of the proppant and mechanically locked with the proppant in the composite. 2. The method of claim 1, wherein the proppant used to make the composite has an internal porosity of about 4 to about 40 volume percent. 3. A method of fracturing a subterranean formation, the method comprising: suspending a proppant in a fluid comprising an aqueous-based carrier and a superabsorbent polymer to form a proppant-containing fluid;combining the proppant-containing fluid with a gaseous fluid to form a fracturing composition, the gaseous fluid constituting less than about 50 volume percent, and a sum of the volumes of the gaseous fluid, the proppant, and the superabsorbent polymer is greater than about 50%, each based on the total volume of the fracturing composition; andintroducing the fracturing composition into the subterranean formation,wherein the superabsorbent polymer comprises a repeating unit derived from an acrylic acid or a salt thereof, an acrylate, an acrylamide, a vinylpyrrolidone, a vinyl acetate, a vinyl alcohol, a 2-acrylamide-2-methylpropanesulfonic acid, a derivative thereof, or a combination thereof; andinternal crosslinks formed before the superabsorbent polymer is combined with the aqueous-based carrier. 4. The method of claim 3, wherein the fracturing composition comprises about 0.5 to about 50 pounds of the superabsorbent polymer per one thousand gallons of the proppant-containing fluid. 5. The method of claim 3, wherein the fracturing composition further comprises a viscosity modifying agent comprising a polysaccharide, a viscoelastic surfactant gelling agent, an uncrosslinked polymer comprising repeating units derived from one or more of the following monomers: an acrylate; an acrylamide; a vinylpyrrolidone; a vinyl ester; a vinyl alcohol; or a 2-acrylamide-2-methylpropanesulfonic acid, or a combination comprising at least one of the foregoing. 6. The method of claim 3, wherein the fracturing composition is free of a viscosity modifying agent. 7. The method of claim 3, further comprising pumping a pad fluid comprising a second gaseous fluid into the formation at a pressure sufficient to initiate a fracture. 8. The method of claim 7, wherein the pad fluid comprises the second gaseous fluid and an aqueous fluid.
