摘要： 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.

摘要： The present invention provides improved foamed well cement slurries, additives and methods. The additives, which foam and stabilize a cement slurry containing fresh water or salt water, are basically comprised of a mixture of an ethoxylated alcohol ether sulfate surfactant, an alkyl or alkene amidopropyl betaine surfactant and an alkyl or alkene amidopropyl dimethyl amine oxide surfactant.

摘要： Well bore servicing fluids are provided that include a thermally activated viscosification compound. Further, methods of servicing a well bore are provided that include displacing such a servicing fluid into the well bore, wherein a viscosity of the servicing fluid increases as it passes down the well bore due to its temperature increasing. Thus, the viscosity of the servicing fluid is effective to suspend solids therein when the servicing fluid is in the well bore. The servicing fluid may be, for example, a cement slung, a drilling fluid, a gravel packing fluid, a fracturing fluid, a completion fluid, or a work-over fluid. In an embodiment, the thermally activated viscosification compound includes at least one water-soluble hydrophobically modified polymer comprising a hydrophobic substituent having from about 1 to about 22 carbon atoms.

摘要： Improved methods of generating gas in and foaming aqueous well fluids introduced into a subterranean zone are provided. A method of the invention includes the steps of combining with an alkaline aqueous well fluid one or more gas generating chemicals and a mixture of foaming and foaming stabilizing surfactants so that the gas generating chemical or chemicals react with the alkaline aqueous well fluid and gas and foam are formed in the well fluid while it is being pumped, and then pumping the well fluid into the subterranean zone.
