Abstract
The present invention relates to improved methods of sealing openings in a well bore penetrating a subterranean zone into which fluids contained in the well bore are lost or from which fluids undesirably flow into the well bore. The methods basically comprise the steps of preparing a hardenable epoxy sealing composition comprising an epoxide containing liquid and a hardening agent, placing the epoxy sealing composition by way of the well bore into the openings and into the subterranean zone and allowing the epoxy composition to harden whereby the well bore is sealed.
