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.

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: This disclosure relates to acidizing retarder compositions and methods of reducing the rate of carbonate dissolution in carbonate acidizing treatments of carbonate formations using the acidizing retarder compositions. The methods may include dissolving one or more retarder compounds in a solution comprising a strong acid to form acidizing retarder compositions, and introducing the acidizing retarder compositions to carbonate formations. The acidizing retarder compositions may include one or more retarder compounds and a strong acid. At least one of the one or more retarder compounds may be a poloxamer. A concentration of the strong acid in the acidizing retarder composition may be 5 weight percent or greater.
