Abstract

A method for fracture stimulation of a subterranean formation having a wellbore includes providing a thermoset polymer nanocomposite particle precursor composition comprising a polymer precursor mixture, dispersed within a liquid medium, containing at least one of a monomer, an oligomer or combinations thereof having three or more reactive functionalities capable of creating crosslinks between polymer chains, wherein 1% to 100% by weight of said polymer precursor mixture is obtained or derived from a renewable feedstock; and from 0.001 to 60 volume percent of nanofiller particles possessing a length that is less than 0.5 microns in at least one principal axis direction; subjecting the nanocomposite particle precursor composition to polymerizing conditions to form the polymeric nanocomposite particle, whereby said nanofiller particles are substantially incorporated into a polymer; forming a slurry comprising a fluid and a proppant, wherein said proppant comprises the nanocomposite particles, said nanocomposite particles being formed from a rigid thermoset polymer matrix; and injecting into the wellbore said slurry at sufficiently high rates and pressures such that said formation fails and fractures to accept said slurry.
