Methods and ultra-low density sealing compositions for sealing pipe in well bores |
| abstract |
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. |
