Abstract:
Downhole tools comprising a body, wherein at least a portion of the body is degradable when exposed to a wellbore environment; and at least one aqueous-degradable sealing element comprising an aqueous-degradable elastomer comprising in the range of 0.05 to 1 parts by weight per hundred parts of the elastomer (phr) carbodiimide, wherein at least a portion of the aqueous-degradable sealing element hydrolytically degrades when exposed to an aqueous fluid.
