Abstract
The present invention provides improved methods of sealing a bridge plug or the like in a pipe disposed in a well bore. The methods basically include the steps of preparing a hardenable epoxy sealing composition which hardens into a resilient solid mass having a high pipe surface bond strength, placing the epoxy composition into the pipe adjacent to the bridge plug therein and allowing the epoxy composition to harden.
