    摘要: The design method for complex electromagnetic materials is expanded from form-invariant coordinate transformations of Maxwell's equations to finite embedded coordinate transformations. Embedded transformations allow the transfer of electromagnetic field manipulations from the transformation-optical medium to another medium, thereby allowing the design of structures that are not exclusively invisible. A topological criterion for the reflectionless design of complex media is also disclosed and is illustrated in conjunction with the topological criterion to design a parallel beam shifter and a beam splitter with unconventional electromagnetic behavior.

    摘要: A method and apparatus for the management of injection and production of well fluids in a subterranean well is described to optimize the use of stimulation fluids to enhance their compatibility with subterranean reservoirs and the surface environment and thereby reducing the damage said fluids induce in subterranean reservoirs and upon flow back to the surface reduce their damage to the environment is described. More specifically, this method is directed to the subterranean treatment of injection fluids.

    摘要: The application discloses a safety valve including a flapper valve and a packer assembly to be installed in a bore to isolate a first zone from a second zone. Preferably, the safety valve includes a hydraulic conduit bypassing the flapper valve to allow communication therethrough when the valve is closed. Furthermore, the safety valve preferably allows unobstructed passage of tools and fluids therethrough when the flapper valve is open. The application discloses a method to install a safety valve in an existing string of tubing by deploying a packer assembly having an integral safety valve.
