Abstract: An improved wellhead electrical connection assembly utilizing upper and lower retention mechanisms to minimize pressure and fluid leakage in the event of a tubing part or other failure. The upper retention mechanism ensures the connection assembly remains within a tubing hanger. The lower retention mechanism provides a secure connection to a downhole cable that can breakaway without damaging or dislodging other components of the assembly during an emergency event.

Abstract: A connecting assembly for connecting a first body and a second body includes a connector having a plurality of segments and a main piston positioned around at least a portion of the connector. The connector includes: a channel that extends longitudinally through the connector from a first end to a second end; a plurality of teeth formed on an inside of the connector near the first end and near the second end; a first jaw formed of at least one teeth near the first end; and a second jaw formed of at least one teeth near the second end and axially spaced apart from the first jaw. Each of the plurality of teeth has a leading side facing an axial center of the connector, a top side, a contact point at a transition between the leading side and the top side, and a trailing side opposite the leading side. The teeth of the second jaw include: a first tooth axially closer to the axial center of the connector than the remaining teeth of the second jaw and an end tooth axially farther from the axial center of the connector than the remaining teeth of the second jaw.

Abstract: An electrical feedthrough assembly has a lower assembly having a first end and a second end. The lower assembly includes an outer body with a lower housing and an upper housing disposed within a bore of the outer body and a first conductor extending from the lower housing to the upper housing. Additionally, the lower housing extends axial outward from the outer body to form the first end and the upper housing extends axial outward from the outer body to form the second end. Further, the electrical feedthrough assembly has an upper assembly having body extending from a first end to a second end. The second body includes a pin end at the first end and the pin end is inserted into an opening of the second end of the lower assembly. A second conductor is disposed within the body. A chamber within the body holds the first conductor.

Abstract: A tensioning system includes a combined rope gripper and tension cylinder. A rope passes through the combined rope gripper and tension cylinder. Once the length and/or tension of the rope has been adjusted, a reel lock handle can be actuated to prevent further rotation of the reel. The combined rope gripper and tension cylinder can be actuated to hold the rope. The combined rope gripper and tension cylinder can also be actuated to reduce or prevent the release of tension in the rope.

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) at least a first seal section on the adapter sealingly contacts a first seal bore on the housing assembly. Progressive engagement of a locking ring upon the locking elements urges the locking elements to tighten against the adapter. Internal pressure encourages adapter displacement, which then further tightens the adapter against the locking elements as now restrained by the locking ring. Internal pressure further encourages the first seal section on the adapter to expand radially to tighten the contact with the first seal bore in the housing assembly.
