    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.

    摘要: Cement is conditioned, cured and/or tested while applying a specified temperature and/or pressure. In certain embodiments, the specified temperature and/or pressure applied during the testing substantially simulates anticipated static downhole conditions the cement will be subjected to in use. In certain embodiments, the specified temperature and/or pressure applied during the receiving substantially simulates pumping placement conditions the cement will be subjected to in use. In certain embodiments, the cement can be conditioned in a conditioning vessel while applying specified temperature and/or pressure to the cement. In certain embodiments, the temperature and/or pressure applied in the conditioning substantially simulates anticipated pumping placement conditions the cement will be subjected to in use.
