Abstract: 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.

Abstract: A tool with a deformable element that is configured to flex across an annulus based on a force being applied to an inner surface of the deformable element. The deformable element may be configured to be positioned within a chamber that is covered by a first rupture disc. The deformable element may include seals, flex joints, and a body.

Abstract: A wiper plug to activate an internal sleeve positioned within a landing collar, wherein the landing collar and the internal sleeve are integral components

Abstract: A downhole tool with a flapper positioned within a mandrel. More specifically, embodiments are directed toward flappers with different mechanisms to open and close the flapper.

Abstract: A weld joint and method of welding a joint in parts subject to expansion in use. The weld joint is between dissimilar steel alloys and a weldable nickel-base shim is located between faces of the steel alloys prior to welding by an electron beam. Embodiments of an expandable metal sleeve and a metal packer for use as an isolation barrier in a well, are described which include the weld joint.

Abstract: A high expandable straddle and a method of providing annular isolation at a location in a well bore. The straddle includes two expandable pipe sections with a base pipe section therebetween and end pipe sections for connection in a tubular string. The straddle may be run in tubing with restricted inner diameters and by the introduction of pressure to the saddle over 30% expansion can occur to the expandable pipe sections to seal and grip the tubing spanning a fault. An embodiment is described with the straddle being of unitary construction, the expansion pipe sections having thinned walls and being entirely formed of an austenitic stainless steel. An anchoring arrangement and/or seals may also be located on the expandable pipe sections.

Abstract: A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.

Abstract: A wiper plug to activate an internal sleeve positioned within a landing collar, wherein the landing collar and the internal sleeve are integral components.

Abstract: A tool to remove portions of casing from a wellbore. A tool may include a bottom sub-assembly and casing that selectively detach from a sub-assembly. This may allow for tools and casing within the wellbore to be efficiently and effectively removed from the wellbore without having to cut tools down well.

Abstract: 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.

Abstract: A frac plug with a flapper positioned within a shearable housing. More specifically, embodiments are directed towards an upper portion of the shearable housing that is configured to be separated from an insert responsive to flowing back through the frac plug.

Abstract: A dissolvable frac plug with an internal chamber surrounded by an external wall with the chamber containing a tracer compound in an amount sufficient to be observed from water or other wellbore fluids when released. The tracer compound is released from the chamber as a portion or portions of the external wall dissolves due to contact with water or other wellbore fluids. The released tracer compound can be monitored from the water or other wellbore fluids.

Abstract: A frac plug with a flapper, wherein the flapper is configured to set and unset based on a pressure differential and/or fluid flow associated with the frac plug.

Abstract: A downhole coupling mechanism for use in downhole tools that find application in wells exploited by a hydraulic refracturing process. The downhole coupling mechanism connects first and second tubular sections via a tensile load arrangement of wires located in complimentary grooves, a torque arrangement of interlocking lugs and notches on opposite ends, and a seal arrangement. The downhole coupling mechanism provides a thin walled coupling where a screw-threaded connection could not achieve the required tensile load, torque and sealing properties needed. Embodiments of a thin walled anchor and packer including the downhole coupling mechanism are described.

Abstract: A toe sleeve that is configured to allow communication between an inner diameter of the tool and an annulus outside of the tool during a bleed off cycle, which occurs after testing the casing. To test the casing, pressure within the inner diameter of the tool may be increased, and during a bleed off cycle the pressure within the inner diameter of the tool may be reduced.
