    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： A process for providing a protective layer to an article. The process includes depositing a layer of material onto a surface of the article with a thermal spray process. Examples of thermal spray process include high velocity oxygen/air fuel, atmospheric plasma spray, and chemical vapor deposition. Coating methods, such as cold vapor deposition and physical vapor deposition, may also be used. The layer can then be bonded to the article by heating material in the layer adjacent its connection with the article. Bonding the layer to the article can be performed by irradiating the layer with a collimated light source, the layer irradiation can be applied concurrently with the thermal spray process

    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.

    摘要： A method for mitigating crack initiation and propagation on a surface of a metal component due to susceptibility to corrosion comprises depositing a metallic material on the surface of the component to form a coating, and then converting at least an outer layer of the coating to an electrically insulating material. The deposition of the metallic material is carried out by a method selected from the group consisting of wire-arc spraying, physical vapor deposition, and chemical vapor deposition. Electrochemical corrosion potential less than −0.23 VSHE based on the standard hydrogen electrode can be achieved with the method of coating of the present invention. This method is applied to produce coated structural components of water-cooled nuclear reactor.
