Abstract: Fracturing a reservoir includes providing a pad fluid to the reservoir via a wellbore in a well to create fractures in the reservoir, providing a fracturing fluid to the fractures via the wellbore, providing a nanosilica carrier fluid to the fractures via the wellbore, activating the nanosilica particles with an activator to yield a nanosilica gel, and shutting in the wellbore at a wellbore pressure, thereby allowing the nanosilica gel to form proppant pillars in the fractures. The nanosilica carrier fluid includes nanosilica particles, and providing the nanosilica carrier fluid to the fractures comprises pulsing quantities of the nanosilica carrier fluid into a continuous flow of the fracturing fluid or alternately pulsing quantities of the nanosilica carrier fluid and the fracturing fluid. An elapsed time between pulsing the quantities of the nanosilica carrier fluid is between 2 seconds and 10 minutes.

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 polymer gel composition for treating an aqueous zone of a subterranean formation may include a base polymer, a cross-linking agent, and an adsorption system. The adsorption system may include one or more silane compounds or a combination of silane compounds and silicates. The adsorption system may improve bonding of the polymer gel composition to the pore surfaces of the rock in the aqueous zone. A method of treating an aqueous zone of a subterranean formation may include injecting the polymer gel composition into the aqueous zone of the formation and allowing the polymer gel composition to cure to form a cross-linked polymer gel matrix that provides a barrier that reduces or prevents the flow of aqueous materials from the aqueous zone to the wellbore.
