Thermally stable, nonionic foaming agent for foam-fracturing fluids

摘要

A method foamed fracturing may include providing a wellbore that extends into a subterranean formation and introducing a foamed fracturing fluid into the subterranean formation at a pressure sufficient to create or enhance at least one fracture in at least a portion of the subterranean formation. The foamed fracturing fluid may generally include an aqueous base fluid, a sugar derivative foaming agent, and a gas. 28/06/12,ck2009Ospecification.2
