    摘要: A bridge plug assembly that can be set in a wellbore tubular using wellbore pressure to form a pressure differential on a piston that actuates sliding members. A resilient member, such as a spring, is compressed from a downhole pressure differential. The bridge plug assembly can be removed by equalizing pressure across the piston and the spring. The spring can expand and re-stow the expanded plug. The plug can be formed from a nickel titanium alloy flexible member that can be selectively radially expanded so its outer surface sealingly engages a surrounding tubular. The percentage of weight of nickel can range up to about 40 to about 58%, 55% or to about 60%.

    摘要: A bridge plug assembly having a mandrel and an annular flexible member that is selectively fashioned into a volute that extends radially outward from the mandrel for isolating a portion of a tubular. In an example, a web member is provided that runs between the flexible member and the mandrel, and exits an end of the flexible member. Pulling the web member inverts an end of the flexible member rolling the sidewall of the flexible member into a volute. In another embodiment, upper and lower series of collars circumscribe the mandrel that when pushed towards one another axially squeeze the flexible member therebetween to outwardly bulge the flexible member into contact with a tubular. Continued force applied to the collars causes the flexible member to roll into a volute.

    摘要: A method of modifying polarity of light is provided. The light propagates through a first transverse plane and has known polarization states in respective cells of the first transverse plane. A first retardation compensator having respective waveplates matching the cells then changes the polarity of the light so that light propagating through a second transverse plane is circularly polarized across the entire second transverse plane. A second retardation compensator includes a plurality of quarter waveplates that change the polarization of the circularly polarized light, so that light passing through a third transverse plane is linearly polarized. The crystal alignment of the quarter waveplates and their shape and configuration are selected so that the direction of the polarization is normal to a radius from a single point.
