A telemetry tool assembly for exploiting subsurface fluids and minerals through well construction and production. The assembly comprises a tube comprising a bore and a bore wall and first end and a second end. The respective ends each comprise internal and external upset portions welded to a pin end tool joint or box end tool joint, respectively. The upset portions comprise an internal and external conical transition section intermediate the respective tool joints and the tube. The external conical transition section comprises at least one socket comprising a removeable cover and side and bottom surfaces within the external conical transition section. The socket and cover comprise a seal between the cover and socket side walls. A telemetry adapter comprising electrical equipment is disposed within the one or more sockets and the assembly comprises a wired drill pipe (WDP). The socket surfaces comprise a hardness greater than the transition section.

Downhole tools, systems, and methods for electric-based fracturing are disclosed. A downhole tool for electric-based fracturing may include an outer enclosure, an insulator chamber disposed at least partially within the enclosure, and an electrode disposed at least partially within the insulator chamber. The electrode may extend out from the insulator chamber and the enclosure, and may be configured to transfer electric energy to an exterior environment surrounding the downhole tool. The insulator chamber may be configured to thermally and electrically insulate at least a portion of the electrode from the exterior environment.

A perforating gun assembly may include a first perforating gun housing, a first shaped charge provided within the first perforating gun housing, and an alignment sub coupled to the first perforating gun housing. The alignment sub may include a first sub body and a second sub body rotatably coupled to the first sub body.

A telemetry tool joint may comprise a tool joint body adapted for connection to a downhole tubular as part of a tool string. The tubular may be a drill pipe or a downhole tool such as a drill bit or component of a bottom hole assembly. The tool joint body may comprise an axial bore comprising a bore wall having an interior wall surface and a tapered outer wall surface. The tapered outer bore wall surface may comprise a first continuous thread form having multiple turns comprising a first thread start and a first thread end and a second continuous thread form having multiple turns comprising a second thread start and a second thread end. The respective thread forms may be separated by a gap along the tapered outer bore wall surface. The gap may comprise one or more annular recesses adapted for housing a radially oriented inductive coupler.

An apparatus and downhole tool having a releasable locking mechanism for holding a line reliably connected to a tool in a wellbore for providing communication with and/or power to the tool, the releasable locking mechanism has: a movable holding device that can be in a locked state for holding the line reliably connected to the downhole tool or in a released state for allowing release of the line from the tool; and a movable locking device that can be in a locking state wherein the movable locking device engages with the movable holding device in a manner that restricts movement of the movable holding device, thereby locking the movable holding device in its locked state, or that can be in a releasing state for releasing the movable holding device to its released state.

A perforation gun having a modified pin end for positioning a blast shield between adjacent guns, the blast shield electrically joining movable contact pins and propagating firing signals between while protecting against blast forces from previous explosions. The perforation guns also having a wiring port in the charge carrier and alignment pin for opening and adding detonation circuitry at time of use, positioned within the charge carrier where it is protected from damages caused by rough handling, flooding, vibrations, and blast forces.

An electrical power connector for an electrical submersible well pump motor has a housing having a bore. A pair of rigid insulators are within the bore of the housing, each of the insulators having a cylindrical outward-facing side that is in contact with an inward-facing side wall of the housing. A resilient elastomer seal is sandwiched between the insulators in sealing engagement with the inward-facing side wall. Passages extend through each of the insulators and the elastomer seal for receiving insulated conductors of a power cable. A spring in abutment with one of the insulators exerts an axial compressive force on the elastomer seal.

Systems and methods are provided to facilitate connection of multiple stage completions. A first completion stage is deployed at a wellbore location. Subsequently, the next completion stage is moved downhole into engagement with the first completion stage. The completion stages each have communication lines that are coupled together downhole via movement of the completion stages into engagement.

A method including, without removing a BHA from a wellbore of a well extending into a formation, extending, into an interior flow bore of the BHA, a first component of a wet latch assembly to provide an extended first component of the wet latch assembly, conveying downhole via a wireline cable, from a surface through an interior flow bore provided by a drill string, a second component of the wet latch assembly, and coupling the second component of the wet latch assembly with the extended first component of the wet latch assembly such that an electrical connection is established between the first component and the second component and between the BHA and the surface via the wireline cable, and testing the formation with a formation tester of the BHA, while providing power and/or data telemetry for the formation tester via the wet latch assembly and the wireline cable.

A system and method for hydraulic isolation of a downhole powered system. The system and method include a sliding sleeve, venting assemblies with venting ports, and check valves associated with a vent body, and an isolation sleeve, isolation valve, and integral packer for controlling fluid flow through the motor and pump assembly of the powered system. Also disclosed is a wet connect mandrel modified to receive the isolation sleeve, the isolation sleeve preferably capable of permitting the passage of tools therethrough and capable of preventing fluid through the inlet of the mandrel. The mandrel may also be outfitted with a built in sliding sleeve. The sleeves, valves and packer can be actuated mechanically, hydraulically or electrically. Electrical actuation can be facilitated using the power from an adjacent wet connect mandrel.
