摘要： A nanocomposite including a metal oxide and two-dimensional nanosheets. The metal oxide includes at least one of zirconia and titania, and the two-dimensional nanosheets include at least one of reduced graphene oxide and boron nitride. A weight ratio of the metal oxide to the two-dimensional nanosheets is in a range of 2:1 to 19:1, or in a range or 2:1 to 9:1. Making the nanocomposite includes forming a first aqueous dispersion including zirconia nanoparticles and graphene oxide powder, combining a reducing agent with the first aqueous dispersion, irradiating the first aqueous dispersion with microwave radiation, thereby yielding a second aqueous dispersion including zirconia and graphene, and separating the nanocomposite from the second aqueous dispersion, wherein the nanocomposite comprises zirconia and graphene.

摘要： 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.

摘要： Treating a gas condensate reservoir having a porous formation material includes introducing a formation treatment fluid to the gas condensate reservoir and maintaining the formation treatment fluid in the gas condensate reservoir. The formation treatment fluid is a dispersion including metal oxide nanoparticles, and the gas condensate reservoir includes discrete portions of condensate in contact with the porous formation material.

摘要： 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.

摘要： A foam composition includes a foam stabilizer, a foaming agent, a brine, and an inert gas. The foam stabilizer includes graphene. The foaming agent includes a viscoelastic surfactant. The inert gas is in the form of gas bubbles dispersed through a mixture of the foam stabilizer, the foaming agent, and the brine. The foam composition is configured to convert to a gel that is substantially impermeable to fluid flow in response to exposure to downhole conditions of a subterranean zone.
