    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： Well completion spacer fluids containing fibers and methods of using the spacer fluids are provided. A method of the invention for displacing a first fluid from a well bore with an incompatible second fluid comprises the following steps. A spacer fluid is placed between the first and second fluids to separate the first and second fluids and to remove the first fluid from the walls of the well bore. Thereafter, the first fluid and the spacer fluid are displaced from the well bore with the second fluid. The spacer fluid comprises water, a weighting material, a dispersing agent, a suspending agent and friction reducer and fibers. The spacer fluid containing the components mentioned above is preferably also foamed.
