ABSTRACT:
The present invention provides improved methods and compositions for sealing a pipe string 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 high bond strength comprising an epoxide containing liquid, an organosilane compound and a hardening agent, placing the epoxy composition in the annulus between the pipe and the walls of the well bore and allowing the epoxy composition to harden.
