Abstract: One disclosed sleeve assembly disposed within a base pipe includes a first sleeve portion having a first shear resistance for resisting movement of the sleeve assembly with respect to the base pipe, and a second sleeve portion moveable with respect the first sleeve portion and having a second shear resistance for resisting movement of the second sleeve portion with respect to the first sleeve portion, the second shear resistance being greater than the first shear resistance.

Abstract: Systems and methods for remotely setting a downhole device. The system includes a base pipe having inner and outer radial surfaces and defining one or more pressure ports extending between the inner and outer radial surfaces. An internal sleeve is arranged against the inner radial surface and slidable between a closed position, where the internal sleeve covers the one or more pressure ports, and an open position, where the one or more pressure ports are exposed to an interior of the base pipe. A trigger housing is disposed about the base pipe and defines an atmospheric chamber in fluid communication with the one or more pressure ports. A piston port cover is disposed within the atmospheric chamber and moveable between blocking and exposed positions. A wellbore device is used to engage and move the internal sleeve into the open position by applying predetermined axial force to the internal sleeve.

Abstract: Systems and methods for setting a down hole tool include a base pipe having an interior and defining a port that communicates with a pressure chamber positioned outside of the base pipe. A sleeve is positioned in the interior to substantially block the port and to prevent substantial fluid communication between the interior and the pressure chamber. The sleeve includes a first portion having a first shear resistance for resisting movement of the first portion with respect to the base pipe. The sleeve also includes a second portion having a second shear resistance for resisting movement of the second portion with respect to the first portion. Movement of the first portion with respect to the base pipe in response to overcoming the first shear resistance exposes the port to permit fluid communication between the interior and the pressure chamber for setting the down hole tool.

Abstract: An apparatus comprising a first casing string comprising one or more profiled seats furrowed into the first casing string's inner casing wall, a second casing string comprising an upper casing joint, a lower casing joint, and a tension-set external mechanical casing (EMC) packer positioned between the upper casing joint and the lower casing joint, wherein the tension-set EMC packer comprises a mandrel that is attached to the upper casing joint and to the lower casing joint, wherein the second casing string is disposed within the first casing string such that a casing casing annulus (CCA) is formed between the first casing string's inside diameter (ID) and the second casing string's outside diameter (OD), and wherein the recessed seats are positioned below the tension-set EMC packer prior to any engagement of the tension-set EMC packer with the first casing string.

Abstract: An apparatus and method for forming plugs in a wellbore, according to which a first volume of slurry is introduced into a work string in a wellbore so that it flows through the work string and discharges before hardening to form a plug. A second volume of slurry is also introduced into the work string so that it flows through the work string and discharges before hardening to form an additional plug.
