Abstract
The present invention provides improved methods of sealing a string of pipe in a well bore. The methods basically include the steps of preparing a hardenable epoxy sealing composition which hardens into a solid mass having flexibility and resiliency comprising an epoxide containing liquid and a hardening agent, placing the epoxy composition in the annulus between the string of pipe and the walls of the well bore and allowing the epoxy resin to harden.
