    摘要: An assembly and method of manufacturing an assembly for use as an isolation barrier to be run in and secured within a well. The assembly has a sleeve member positioned on the exterior of a tubular body, fixed at each end to create a chamber therebetween. Fluid can enter the chamber through a port in the tubular body to morph the sleeve member against a larger diameter surface in the well. The sleeve member is formed of at least two materials, welded together and machined before being arranged on the tubular body. One material is more expandable than the other so as to morph more easily. The sleeve is connected to the tubular body by screw threads and seals. Initial construction of the sleeve member allows welding, inspection and machining without affecting the tensile strength of the tubular body or complete assembly.

    摘要: A tool comprising a movable sleeve with an inner diameter, an outer diameter, and a screen. The screen being configured to filter materials flowing into a first port within the moveable sleeve, wherein the outer diameter of the movable sleeve is positioned adjacent to an inner diameter of the tool, wherein the screen is configured to move with the moveable sleeve. The tool further comprising a temporary member positioned on the inner diameter of the moveable sleeve, the temporary member being configured to temporarily cover an inner sidewall of the screen.

    摘要: A sliding object positioned on a breakable stem, wherein slips are configured to be engaged, followed by the breakable stem breaking, performing a fracturing procedure above the object, and sliding the object on the stem based on flow back through the frac plug mandrel. The object may be part of the frac plug, and run in the hole along with the frac plug in a single run. This allows the well to be pressure tested, perforated, and re-establish communication without positioning additional tools, sleeves, balls, etc. downhole.

    摘要: A downhole anchor mechanism for use in downhole tools. The downhole anchor mechanism generally consists of a plurality of sliders that pivot outwardly from a downhole tool body to engage distal ends thereof against a well casing. The sliders are operatively engaged within faceted cavities associated with the tool body, which creates load components that act in a tangential direction, allowing a thin-walled tool body to withstand increased holding force.
