Abstract
A method of stimulating a subterranean formation includes preparing an aqueous dispersion including one or more cellulosic nanoparticles. The cellulosic nanoparticles have respective surfaces functionalized with one or more hydrophilic polymers or ligands, one or more hydrophobic polymers or ligands, or a combination thereof. The method also includes pumping the aqueous dispersion into the subterranean formation.
