Abstract

Embodiments for a high temperature fracturing fluid comprise an aqueous fluid, carboxyl-containing synthetic polymer, metal oxide nanoparticles having a particle size of 0.1 to 500 nanometers, and a metal crosslinker which crosslinks the carboxyl-containing synthetic polymers to form a crosslinked gel, wherein the metal oxide nanoparticles are dispersed within the crosslinked gel.
