Abstract
The present invention provides improved methods and compositions for cementing pipe strings in well bores. The methods of the invention are basically comprised of preparing a cement composition comprised of a hydraulic cement, an epoxy resin, a hardening agent for the epoxy resin and sufficient water to form a pumpable slurry. Thereafter, the cement composition is introduced into the annulus between a pipe string and a well bore and the cement composition is allowed to set into a resilient impermeable solid mass.
