<p>A treatment fluid composition for treating a subterranean formation is formed from an aqueous fluid, a hydratable polymer and a polymer breaking system. The polymer breaking system includes an oxidizing breaking agent and an activator capable of providing a bisulfite ion source. A method of treating a subterranean formation may also be performed by forming a treatment fluid comprising an aqueous hydrated polymer solution and a polymer breaking system. The polymer breaking system includes a breaking agent of an oxidizer and an activator capable of providing a bisulfite ion source. The treatment fluid is introduced into the formation.</p> |
