High temperature fracturing fluids with nano-crosslinkers

A fracturing fluid system for increasing hydrocarbon production in a subterranean reservoir formation, the fracturing fluid system comprising a fluid composition and a base fluid,

• a. the fluid composition comprising:
• a nano-crosslinker, wherein the nano-crosslinker comprises a nanomaterial and a crosslinker, wherein the crosslinker comprises a chemical group selected from the group consisting of carbonyl, sulfhydryl, amine and imine, wherein the nano-crosslinker is produced by a method selected from the group consisting of pre-treating the nanomaterial with the crosslinker such that the crosslinker has been functionalized onto the nanomaterial, embedding the crosslinker on the nanoparticle, grafting the crosslinker onto the nanomaterial, and coating the crosslinker on the nanomaterial, and
• a base polymer;
• and
• b. the base fluid operable to suspend the fluid composition, the base fluid comprising water;
• wherein the fluid composition and the base fluid are combined to produce the fracturing fluid system, wherein the fracturing fluid system is operable to increase conductivity in the subterranean reservoir formation.
