Remedial well bore sealing method

摘要

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, are sealed by providing a hardenable epoxy sealing composition comprising an epoxide-containing liquid and a hardening agent, by way of the well bore into the openings and into the subterranean zone and allowing the epoxy composition to harden whereby the openings in the well bore are sealed.
