A packer for wells can include a body having a tubular shape, a sealing element having an upward end and a downward end and disposed around the body. The packer also includes a first prop upward of the sealing element, and a second prop downward of the sealing element. The first prop is configured to wedge under the upward end of the sealing element and the second prop is configured to wedge under the downward end of the sealing element to push the sealing element outward at both the upward end and the downward end.

Backup rings for a sealing element system for a downhole bridge plug assembly may include a circumferentially-expandable backup ring body having an engaging ring surface. A beveled ring surface may extend from the engaging ring surface. An interior ring surface may extend from the beveled ring surface to the engaging ring surface. A ring opening may be formed by the beveled ring surface. A plurality of spiral ring slots may extend through the backup ring body from the engaging ring surface to the beveled ring surface. A plurality of expandable ring portions may extend between the plurality of spiral ring slots. An at least partially circumferentially-expanding ring sleeve may extend from the backup ring body. In some embodiments, an outer width or diameter of the ring sleeve may correspond to an outer width or diameter of the backup ring body. The ring sleeve may include a ring sleeve wall extending from the interior ring surface of the backup ring body. A sleeve interior may be formed by the ring sleeve wall. A plurality of sleeve slots may extend through the ring sleeve wall. The plurality of sleeve slots may communicate with the plurality of spiral ring slots, respectively, in the backup ring body. A plurality of expandable sleeve portions may extend between the plurality of sleeve slots. The plurality of expandable sleeve portions may extend from the plurality of expandable ring portions of the backup ring body.

Provided is a slip ring for use with a sealing assembly, a sealing tool, and a method for sealing an annulus within a wellbore. The slip ring, in at least one aspect, includes a ring member having a first end, a second opposing end, a width (w), and a wall thickness (t). The slip ring, in this aspect, may additionally include a slot located entirely through the wall thickness (t) and extending between the first end and the second opposing end, the slot configured to allow the ring member to move between a radially reduced state and a radially enlarged state, and further wherein a first portion of the slot located at the first end and a second portion of the slot located at the second opposing end are radially offset from one another by at least 15-degrees.

An electric motor-actuated packer and/or anchor (EMAP/A) apparatus and method for use in downhole operations. The apparatus includes a packer subassembly and/or a slip subassembly and can be: set in a packer and anchor mode; set in an anchor-only mode without energizing the packer elements; repeatedly set and unset without run-in string manipulation; run in a multiple, or redundant, configuration within a given tool string, with each EMAP/A apparatus capable of being set/unset independently of the others; and combined within a tool string in a straddle packer configuration, with inverted and non-inverted EMAP/As providing the ability to isolate an interval of interest from both above and below the interval. Among other uses, the apparatus and method are well suited for application in a single-trip, e-coil conveyed completion system, and particularly one providing for radial hydraulic jetting.

A method of using a downhole tool that includes the step of operating a workstring to run the downhole tool into a wellbore to a desired position. The downhole tool includes a mandrel having a proximate end with a first outer diameter; a distal end with a second outer diameter; a flowbore; and an inner set of shear threads disposed in the flowbore at the proximate end.

A settable down hole tool is of increased drillability and/or of increased expansibility. The improvement in drillability can be caused by fracturing cast iron slips into a large number of small pieces that can be circulated out of a well without further reduction in size. The improvement in expansibility can be partially caused by providing an expander cone of increased hardness thereby allowing an increased angle on the expander cone and slips. The improvement in expansibility can be partially caused by increasing the thickness of the slips.
