Water-soluble graphene oxide nanosheet assisted high temperature fracturing fluid

1. A fracturing fluid comprising:

an aqueous copolymer composition comprising a terpolymer comprising 2-acrylamido-2-methylpropanesulfonic acid, acrylamide, and acrylic acid monomer units, or a salt thereof;

a graphene oxide (GO) additive selected from a non-modified water-soluble graphene oxide and a bifacial hydrophilically-modified GO-AMPS-AA; and

a crosslinker comprising a metal.

2. The fracturing fluid of claim 1 , wherein the terpolymer comprises about 1 mol % to about 55 mol % of the 2-acrylamido-2-methylpropanesulfonic acid monomer units.

3. The fracturing fluid of claim 1 , wherein the fracturing fluid comprises about 15 to about 50 pounds of the copolymer per thousand gallons (pptg) of the fracturing fluid.

4. The fracturing fluid of claim 1 , wherein the fracturing fluid comprises about 0.01 pptg to about 20 pptg of the graphene oxide additive.

5. The fracturing fluid of claim 1 , wherein the crosslinker comprises zirconium, titanium, or chromium.

6. The fracturing fluid of claim 1 , wherein the weight ratio of the metal to the terpolymer is in a range of 0.01 to 0.10.

7. The fracturing fluid of claim 1 , comprising at least one of a gel stabilizer, a clay stabilizer, a viscosity breaker, a proppant, and a pH adjusting agent.

8. The fracturing fluid of claim 7 , comprising the pH adjusting agent, wherein the pH of the fracturing fluid is between about 2 to about 7.

9. The fracturing fluid of claim 1 , comprising between about 250 mg/L and about 50,000 mg/L of total dissolved solids.

10. The fracturing fluid of claim 1 , wherein the fracturing fluid has a viscosity that is reduced by about 5% to about 65% as compared to the same fracturing fluid that does not contain the graphene oxide additive.
