  • Patent number: 10184313
    Abstract: A packer with a slip assembly utilizing retainable wing projections. The slip assembly is configured for anchoring the packer in a well upon setting. This setting or deployment of the slip assembly involves shearing of wing projections from the sides of the slips. In this way, the retaining of the wings by counterbore projections of the packer ceases to keep individual slips also retained. That is, the shearing now allows the slips to expand radially into the noted anchoring position. Additionally, utilizing this type of wing shearing for setting allows the wings and indeed, the majority of the slips to be of a composite polymer or other readily millable or otherwise removable material. Thus, following the isolation, a more efficient packer removal may be realized.

  • Patent number: 9828827
    Abstract: A composite plug that can be used in fracturing has backup rings for the seal that are preferably made of a composite material. The backup rings are essentially connected segments that allow the connections to break when the plug is set and the cones are brought closer together. When the rings break to form gaps between segments in a specific ring, the adjacent ring has offset gaps so that as a whole there are no extrusion gaps that would allow the seal element to pass. The rings can be rotationally locked to each other initially at the adjacent segments that are formed when the plug is set to maintain their relative positions so that gaps between segments adjacent the seal are overlapped with segments from the adjacent ring. The segmenting backup rings can be used on one or on both sides of a sealing element.

  • Patent number: 7694746
    Abstract: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.

  • Patent number: 5690172
    Abstract: The invention relates to a seal-sub packer assembly which is formed by a two-mandrel packer and a setting tool which positions the packer within the casing. A lower mandrel of the packer is provided with internal threads for engagement with the setting tool, thereby preventing premature setting of the packer. The exterior surface of the lower mandrel carries one or more sealing members which are compressed and forced to expand horizontally when the upper mandrel slides downwardly, shearing shear screws in response to a downward force acting on the setting tool. In an alternative embodiment, a liner hanger is secured to the lower mandrel, the liner hanger carrying an annular band with an inverted J-shaped slot through which a pin extends. When the body of the packer assembly is rotated in a predetermined direction, the guide pin extending through the J-slot resists premature setting of the packer.

    Abstract: A downhole packing mechanism for achieving sealed engagement with the bore of a well conduit comprises a mandrel positionable within a well by a tubing string. Surrounding the mandrel is a tubular body assemblage which is connectable to the mandrel for run-in purposes by a control dog and slot arrangement. An annular packing element surrounds the upper end of the tubular body assemblage and is compressed into sealing engagement with the well bore conduit by an upper slip assembly. A lower slip assembly surrounds the tubular body assemblage and is detachably engagable with the mandrel for setting by initial upward movement of the mandrel. Subsequent upward movement of the mandrel effects the upward movement of the upper slip assembly, the compression of the annular packing element into sealing engagement with the well conduit and the setting of the upper slip assembly. The device may be used as a packer, bridge plug, tubing hanger, or the like.

Cement is pumped down a tubing string, through the packer, the lining, check valves and forced upwardly in the annulus of the well bore. The pumped cement is followed by a non-setting liquid to clear the internal tubular structure. The packer assembly is then set in the wet cement of the annulus to provide an additional fluid seal in the well bore. The packer setting tool is released and the cement is allowed to harden and fix the linear and the packer assembly within the well bore.

    Abstract: A bridge plug tool is disclosed, for temporarily plugging off a well casing to perform a downhole operation, such as cementing, or acidizing. The tool includes a mandrel having separate thread segments thereon. During running in of the tool, one thread segment engages a set of control members, to keep the mandrel in place and to prevent it from shifting longitudinally. In the set position the control members are disengaged from the mandrel, and the other thread segment engages a set of lock members. Setting weight on the mandrel after engagement with the lock members causes a set of slips and packing elements to engage the casing wall. When the downhole job is finished, the mandrel is rotated to disengage from the lock members and to re-engage the control members. This sequence releases the slips so the tool can be retrieved from the casing, or re-set at another point in the casing.
