Abstract
Methods and compositions for treating aqueous fluids that may be included in treatment fluids that are used for treating a subterranean formation. In some embodiments, the methods include: providing a treatment fluid including an aqueous fluid and a composition that includes an oxygen scavenger, a pH-adjusting agent, and a corrosion inhibitor, wherein the aqueous fluid is aerated; contacting a metal surface with the treatment fluid; and introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation.
