The treatment fluid may include from 40 weight percent to 70 weight percent acidizing fluid based on the total weight of the treatment fluid. The treatment fluid may include from 20 weight percent to 40 weight percent nanoparticle dispersion based on the total weight of the treatment fluid. The treatment fluid may include from 5 weight percent to 15 percent activator based on the total weight of the treatment fluid. Methods of treating a subterranean formation with the treatment fluids are also disclosed.

Abstract: An emulsion for hydraulic fracturing to provide a one-step delivery of a fracturing fluid and a breaker for hydraulic fracturing of a hydrocarbon-bearing formation is provided. The emulsion for hydraulic fracturing is a water-in-oil-in-water emulsion having an internal aqueous phase that includes a breaker, an external aqueous phase that includes a fracturing fluid and a proppant, and an intermediate hydrocarbon phase separating the internal aqueous phase and external aqueous phase. The emulsion may include nanometer-sized or micrometer-sized particles to form a Pickering emulsion.

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 lost-circulation material including a mixture of an aqueous colloidal dispersion and fatty acid. The aqueous colloidal dispersion includes silica nanoparticles and has a pH of at least 8. Combining the colloidal dispersion and the fatty acid initiates gelation of the lost-circulation material when the pH of the lost-circulation material is less than 8 and a temperature of the lost-circulation material is in a range of 5° C. to 300° C. Sealing an opening in a portion of a wellbore or a portion of a subterranean formation in which the wellbore is formed may include providing the aqueous colloidal dispersion and the fatty acid to the wellbore, mixing the colloidal dispersion and the fatty acid to yield the lost-circulation material, initiating gelation of the lost-circulation material, and solidifying the lost-circulation material in the wellbore to yield a set gel.
