Abstract:
A method for degrading a downhole article includes exposing the downhole article comprising a controlled electrolytic material to a composition that comprises a reducing agent. The method also includes contacting the downhole article with the reducing agent to degrade the downhole article. Additionally, a composition for degrading a downhole article includes water, chelant, metal ions, and a reducing agent that includes ascorbic acid, erythorbic acid, a derivative thereof, a salt thereof, or a combination thereof.
