Abstract

A method of dissolving a tool includes, positioning the tool within an environment reactive with at least a portion of the tool, introducing the environment below a surface of the tool through at least one perforation formed therein, reacting at least a portion of the tool exposed to the environment through the at least one perforation, weakening the tool to mechanical stress, and fracturing the tool.
