Abstract
Compositions for foamed fracturing fluids and methods of using a foamed fracturing fluid. A foamed fracturing fluid is introduced into a wellbore penetrating the subterranean formation at a pressure sufficient to create and/or expand a fracture in the subterranean formation. The foamed fracturing fluid is a formulation of an aqueous base fluid, a polymeric gelling agent comprising acrylamide and phosphonate monomers, a hydration aid, a foaming agent, a crosslinker, a gel stabilizer, an oxidative breaker, a pH adjustor, and a gas constituent of carbon dioxide, nitrogen, or a combination of carbon dioxide and nitrogen. The polymeric gelling agent of the foamed fracturing fluids may be broken as described herein to then release a phosphonate degradation product. The phosphonate degradation product may persist in the wellbore to inhibit scale formation as the well is brought to production.
