Abstract
An improved wiper plug and methods of using the plug during casing and cementing operations within a subterranean wellbore are provided. The present plugs may pre-loaded with at least one engineered material and operative to release the material over time at a target location within the wellbore, such release serving to enhance the degradation of dissolvable components within the plugs and/or within the casing string, and/or to alter the chemical properties of the wellbore environment.
