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.
Claims20
A method comprising:
- providing a treatment fluid comprising an aqueous fluid and a composition that comprises 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.
A method comprising:
- providing a fracturing fluid comprising an aqueous fluid, one or more additives, and a composition comprising an oxygen scavenger, a pH-adjusting agent, and a corrosion inhibitor, wherein the aqueous fluid comprises dissolved oxygen gas in an amount of from about 4 ppm to about 14 ppm;
- contacting a metal surface with the fracturing fluid;
- and
- introducing the fracturing fluid into the wellbore at or above a pressure sufficient to create or enhance one or more fractures within the subterranean formation.
A fracturing fluid comprising:
- an aqueous fluid comprising dissolved oxygen gas;
- and
- a composition comprising an oxygen scavenger, a pH-adjusting agent, and a corrosion inhibitor.
