An outer diameter of a mandrel with a recess to accommodate lower slips with a larger thickness, a sealing element with a concave outer diameter to control a pressure differential caused by a Bernoulli Effect across the sealing element, and a disc that is selectively secured to a housing via a removable shear pin, wherein shear pins with different pressure ratings may be inserted into the housing.

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.

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.

A downhole tool having a mandrel and a slip. The mandrel has a mandrel body having a proximate end; a distal end; and an outer surface. The slip is a hybrid slip having a slip shell engaged with a slip core. When the slip shell is engaged with the slip core, at least one break point of the slip shell is aligned with a respective break point of the slip core.

A transforming bridge-to-flow-through frac plug has a mandrel, a retaining sleeve, a pair of cones, a pair of slips, a packing element, and a keeper ring. The mandrel is concentrically connected within the retaining sleeve, and is constructed of a dissolvable material such that the mandrel is dissolvable through application of a solvent in order to form a big bore flow-through frac plug if removal of the frac plug by milling is not possible. The pair of cones, pair of slips, packing element, and keeper ring are positioned on the exterior of the retaining sleeve in order to secure the frac plug in place after a setting operation, even if the mandrel is dissolved in order to form the big bore flow-through frac plug.

A downhole tool suitable for use in a wellbore, the tool having a cone mandrel having a dual-cone outer surface. The downhole tool includes a carrier ring disposed around one end of the cone mandrel, and a seal element disposed around the carrier ring. There is a slip disposed around or proximate to an other end of the cone mandrel.

A packer assembly includes a mandrel and a packing element disposed about the mandrel. Upper and lower recovery sleeves are disposed about the mandrel and extend between the mandrel and respective upper and lower ends of the packing element. The upper and lower recovery sleeves each have a recovery profile embedded within the packing element. Upper and lower backup assemblies are movably disposed about the respective upper and lower recovery sleeves, adjacent to the respective upper and lower ends of the packing element. The packer assembly includes at least one release mechanism. When setting the packer assembly in a bore, the packing element is axially compressed between the upper and lower backup assemblies to contact the bore wall, and the upper and lower backup assemblies splay outwards. Upon release, the packing element and backup assemblies retract, thereby facilitating retrieval of the packer assembly from the bore.
