Abstract: A fracturing fluid can include: a base fluid, wherein the base fluid comprises water; proppant; a friction reducer; and a friction reducer enhancer, wherein the friction reducer enhancer is a surfactant. The friction reducer enhancer can be in a concentration greater than or equal to a critical micelle concentration. Methods of fracturing a subterranean formation can include introducing the fracturing fluid into the subterranean formation. The friction reducer enhancer can increase the hydration rate of the friction reducer, whereby friction reduction of the fracturing fluid can occur much faster than without the friction reducer enhancer.

Abstract: A silane-modified colloidal silica in the form of a Pickering emulsion and a method for enhancing recovery of hydrocarbons and improving conformance using it. When injected into an oil well, the silane-modified colloidal silica separates into an aqueous phase and oil/oleic phase. The aqueous phase forms a gel that blocks the flow of water and the oleic phase that forms permits oil to flow out of the well.
