Abstract:
A method of recovering hydrocarbons from a subterranean formation comprises introducing a suspension comprising at least one of silica nanoparticles or aluminum silicate nanoparticles into a subterranean formation and contacting surfaces of the subterranean formation with the suspension to form a layer of the at least one of silica nanoparticles or aluminum silicate nanoparticles on at least some surfaces of the subterranean formation. After introducing the suspension comprising the at least one of silica nanoparticles or aluminum silicate nanoparticles into the subterranean formation, the method further includes introducing a solution comprising at least one anionic surfactant into the subterranean formation and extracting hydrocarbons from the subterranean formation. Accordingly, in some embodiments, the nanoparticles may be introduced into the subterranean formation prior to introduction of the surfactant into the subterranean formation. Related methods of recovering hydrocarbons from the subterranean formation are also disclosed.

Claim (Index 9):
The method of  claim 1 , further comprising at least one of water flooding and steam flooding the subterranean formation prior to introducing the suspension comprising at least one of silica nanoparticles or aluminum silicate nanoparticles into the subterranean formation.
