Abstract
A method is provided for producing hydrocarbons from a subterranean reservoir. A mixture of steam and HS-sorbent particles (e.g., nanoparticles) is injected into the subterranean reservoir. This may be performed during the steam phase of a steam injection operation, such as steam assisted gravity drainage (SAGD), steam flooding, or cyclic steam stimulation, which is performed on the reservoir. The injected steam reduces the viscosity of the hydrocarbons in the subterranean formation. The injected HS-sorbent particles attach to the subterranean reservoir and adsorb HS therein. The hydrocarbons are produced to the surface, without producing the HS-sorbent particles with adsorbed HS that remain attached to the subterranean reservoir.
