Abstract: A subterranean formation sealant includes a mixture of an aqueous colloidal dispersion including silica nanoparticles and a C6-C12 fatty acid. Heating the sealant above 70° C. initiates gelation of the sealant. Sealing an opening in a water or gas producing zone in a subterranean formation includes providing a sealant including a mixture of a colloidal dispersion including silica nanoparticles and a C6-C12 fatty acid to the water or gas producing zone, initiating gelation of the sealant in situ, and solidifying the sealant in the water or gas producing zone to yield a set gel, thereby sealing the opening in the water or gas producing zone.

Abstract: A composition useful for subterranean water or gas shut off applications includes organosilane-modified colloidal silica and an accelerator. The accelerator includes one or more organic or inorganic salts. A method of using a composition, including an organosilane-modified colloidal silica and an accelerator, includes forming a fluid system that is flowed to a formation in a subterranean zone, such as through a wellbore, where the composition forms a gel to plug the formation and shut off water flow into the wellbore.
