Enhanced electrolytic degradation of controlled electrolytic material

1. A method for degrading a downhole article, comprising:

exposing the downhole article to a composition comprising a corrosive agent selected from a reducing sugar; and

contacting the downhole article with the corrosive agent to degrade the downhole article at a temperature of about 35° C. to about 150° C.;

wherein the downhole article is degraded at a faster rate in the presence of the corrosive agent as compared to a brine without the corrosive agent; and further

wherein the downhole article is degraded at a slower rate in the presence of the corrosive agent as compared to a mineral acid.

2. The method of claim 1 , wherein the downhole article comprises a metal selected from Group 2, Group 3, Group 4, Group 5, Group 6, Group 7, Group 8, Group 9, Group 10, Group 11, Group 12, Group 13, lanthanoid series, actinoid series of the periodic table, or a combination thereof.

3. The method of claim 2 , wherein the metal is selected from aluminum, calcium, cobalt, copper, chromium, gallium, indium, iron, indium, magnesium, manganese, molybdenum, nickel, nobelium, palladium, scandium, tin, titanium, tungsten, silicon, vanadium, yttrium, zinc, zirconium, or a combination thereof.

4. The method of claim 3 , wherein degrading the downhole article comprises reducing the metal in the downhole article by the corrosive agent or a product of the corrosive agent.

5. The method of claim 1 , wherein reducing the metal in the downhole article comprises oxidizing the reducing sugar.

6. The method of claim 5 , wherein the reducing sugar comprises a monosaccharide, disaccharide, oligosaccharide, polysaccharide, a derivative thereof, or a combination thereof.

7. The method of claim 6 , wherein the reducing sugar includes an aldose, ulosonic acid, or a combination thereof.

8. The method of claim 6 , wherein the reducing sugar includes a ketose, ulosonic acid, ulronic acid, or a combination thereof.

9. The method of claim 6 , wherein the reducing sugar is selected from glyceraldehyde, erythrose, threose, ribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, galactose, talose, dihydroxyacetone, erythrulose, ribulose, xylulose, psicose, fructose, sorbose, tagatose, glucuronic acid, galacturonic acid, cellobiose, maltose, lactose, melibiose, maltulose, lactulose, isomaltose, laminaribiose maltotriose, derivatives thereof, or a combination thereof.

10. The method of claim 3 , wherein degrading the downhole article comprises leaching the metal from the downhole article by a product of the corrosive agent.

11. The method of claim 1 , wherein the composition is substantially free of acid except for the corrosive agent, an acid produced from the corrosive agent, or a combination thereof.

12. A method for degrading a downhole article, comprising:

introducing a composition comprising a reducing sugar into a borehole; and

removing, by the composition, a metal from the downhole article to degrade the downhole article at a temperature of about 35° C. to about 150° C.;

wherein the downhole article is degraded at a faster rate in the presence of the corrosive agent as compared to a brine without the corrosive agent; and further

wherein the downhole article is degraded at a slower rate in the presence of the corrosive agent as compared to a mineral acid.

13. The method of claim 12 , further comprising oxidizing the reducing sugar,

wherein removing the metal comprises reducing the metal in the downhole article by the reducing sugar.
