    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： Oil-based settable spotting fluid compositions and methods of using the compositions are provided. The oil-based settable spotting fluid compositions are basically comprised of oil, an emulsifying surfactant for emulsifying the oil with water whereby an oil-external emulsion is formed, a de-emulsifying surfactant which in time de-emulsifies said oil-external emulsion when the emulsion is contacted with external water, a hydraulic settable component selected from the group consisting of ASTM Class C or the equivalent fly ash and ASTM Class F or the equivalent fly ash together with a source of calcium and water selected from the group consisting of fresh water and salt water.
