    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: The disclosed embodiments include a self-locking coupler, a method to couple adjacent tubing sections, and a self-locking coupling assembly. In one embodiment, the self-locking coupler includes a coupling shroud having an external interface proximate to a first end of the coupling shroud and a set of collet fingers that extends from the first end of the coupling shroud. The self-locking coupler also includes a locking sleeve having an internal interface that complements the external interface of the coupling shroud. The locking sleeve is movable from a first position on the external interface to a second position on the external interface. As the locking sleeve moves from the first position to the second position, the locking sleeve compresses the set of collet fingers into a cavity of a first seal ring coupled to a first tubing section to secure the coupling shroud to the first tubing section.

    Abstract: A shear coupling can be used with reciprocating and rotary pumps. The shear coupling uses a shear nut and connecting member as the shear element. The connecting member and shear nut are located inside the axial bore of the shear coupling to protect from corrosive wellbore elements. The coupling members may be connected by matching polygonal shaft and hub profiles on the coupling members to transmit torque. The shaft and hub may have octagonal profiles for better torque transmission capacity. The shear nut may be isolated from large alternating stresses due to pretensioning of the connecting member. The length of the connecting member, especially when pretensioned, and a reduced cross-section that may be formed on the outer surface of the shear coupling increase the overall flexibility of the shear coupling, thereby increasing the resistance to bending stress.

    Abstract: A downhole assembly that includes tubulars rotationally coupled to one another. An interface is between adjacent tubulars that makes up at least a portion of the rotational coupling. Certain surfaces of adjacent tubulars come into contact with one another when adjacent tubulars are rotationally coupled; and which are defined as contact surfaces. Each contact surface is profiled with facets that are complementary to facets on a corresponding contact surface of an adjacent tubular. The profiling of the contact surfaces is such that when a contact surface is brought together with a corresponding contact surface; facets on the contact surface abut facets on the corresponding contact surface along planes that are oblique or parallel with an axis of the tubular. At least some of a rotational torque transmitted between adjacent tubulars occurs across the abutting facets.

    Abstract: An insert for installation on an inner pipe member of a dual-pipe member assembly. The insert is interposed between an external shoulder formed on the inner pipe member and an internal shoulder formed in an outer pipe member. Shoulder-to-shoulder impacts between pipe members results in wear to the insert, rather than to either pipe member. The insert has the shape of an unclosed loop and is positioned within an endless external groove formed in the inner pipe member.

    Abstract: A remotely-operated fluid connection assembly to hold higher internal pressures in larger diameters. The assembly comprises a fluid connection adapter and a fluid connection housing assembly. When the adapter enters the housing assembly: (A) locking elements on the housing assembly constrict about the adapter; and (B) a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring tightens the locking elements against the adapter. Internal pressure further tightens the adapter against the locking elements and the first seal section against the first seal bore. The fluid connection adapter also provides a release collar in adapter release embodiments. Extension of the locking ring away from the fluid connection housing during disengagement contacts the release collar and separates the fluid connection adapter from the fluid connection housing assembly.

    Abstract: An adapter for a wired drill pipe joint includes an annular adapter body having a first end and a second end, an annular recess extending partially into the first end of the adapter body, a communication element disposed at least partially within the annular recess, wherein the second end of the adapter body is configured to releasably couple to an end portion of a first wired drill pipe joint, wherein the annular adapter body includes an arcuate key that is configured to restrict relative rotation of the adapter body with respect to the first wired drill pipe joint, wherein the annular adapter body and the communication element form a shoulder configured for engagement with a corresponding shoulder of a second wired drill pipe joint to form a rotary shouldered threaded connection between the first wired drill pipe joint and the second wired drill pipe joint.
