The present invention provides methods and ultra-low density sealing compositions for sealing pipe in well bores penetrating formations which readily fracture at low hydrostatic pressures. A method of the invention basically comprises the steps of providing a hardenable ultra-low density sealing composition comprised of an epoxide containing liquid, a hardening agent, a hardening accelerating agent, a light weight filler and hollow glass michrospheres having a density in the range of from about 5 to 8.5 pounds per gallon, placing the sealing composition in the annulus between the pipe to be sealed and the walls of the well bore and allowing the sealing composition to harden therein.
