Systems and methods of the present disclosure relate to protecting a control line as it passes through a junction in a downhole environment. An ETJ deployment tool (ETJDT) comprises a tool body comprising a central bore; at least one first component and at least one second component, each component operable to extend and retract laterally from the tool body, wherein the at least one second component is disposed at an axial distance from the at least one first component along the tool body; a member disposed within the central bore and operable to move forward upon receiving fluid; and a spring disposed axially between a portion of the member and the at least one second component.

A braking and setting device is configured to slow down a movement of a tool in a well and to fix the tool relative to the well. The braking and setting device includes two or more arms configured to extend from the tool, toward the well, to brake the movement of the tool along a longitudinal axis X; a movable piston configured to be hosted fully within the tool and to move only when a well fluid acts on a base portion of the movable piston, while a tip portion of the movable piston pushes away the two or more arms; and an actuation mechanism configured to establish a fluid communication between the well fluid and the base portion of the movable piston. The movable piston moves exclusively due to a force exerted by the well fluid on the movable piston.

An apparatus for remote actuation of a downhole device in a wellbore, that includes a cable head configured to connect with a cable in communication with surface equipment. The cable head is connected with a tractor module. A communication module is connected with the tractor, and a release device is connected with the communication module. The release device is connected with an anchor. The anchor section is connected with a downhole device. The downhole device is configured to communication with the communication module when the communication module is released from the release device.

A hydraulic set packer system includes an outer sleeve and a mandrel extending through the outer sleeve. The mandrel has a setting port extending through a radial wall of the mandrel, and the setting port is configured to provide fluid communication from a central bore of the mandrel to a setting chamber formed between the outer sleeve and the mandrel. The system also includes a piston configured to move axially along the mandrel in response to a setting pressure in the setting chamber. The piston is configured to drive at least one radially actuatable component to actuate in a radial direction to engage a wellbore wall. Further, the system includes a pressure isolation assembly disposed in the setting chamber. The pressure isolation assembly is configured to move axially with respect to the mandrel from a first position to a second position to seal the setting port.

A combination downhole assembly having a setting tool assembly coupled with a downhole tool. The setting tool assembly has an adapter housing configured to couple with a part of a workstring, and a power charge mandrel coupled with the adapter housing. There is a barrel piston releasably coupled with the power charge mandrel. During run-in, the barrel piston is in a first position. Upon activation of a setting sequence, the barrel piston moves to a second position. The setting sequence results in the barrel piston engaging a tension mandrel configured with a deceleration feature.

An annular pressure activated downhole tool has a housing including an outer surface, an inner surface defining a passage, an annular projection projecting into the passage from the inner surface, and an opening. A mandrel extends into the passage. The mandrel has a first end and a second end. A power spring support is detachably connected to the second end of the mandrel in the passage. A power spring is arranged about the mandrel and extends between the power spring support and the annular projection. A trigger housing is arranged in one of the mandrel and the power spring support. A trigger arranged in the trigger housing selectively engages with the inner surface. The trigger is operable to disengage from the inner surface of the housing, releasing the power spring, and shifting the mandrel along the passage when exposed to a selected annular pressure.

The present invention relates to a wireline expansion tool for setting of a completion tubular component such as a straddle, a liner, a patch or a liner hanger, the wireline expansion tool having an axial extension and comprising an electric motor connectable with and powered through a wireline, an axial force generator driven directly or indirectly by the electric motor for providing a movement along the axial extension, a radial expansion tool section connected with the axial force generator, and a completion tubular component, arranged at least partly around at least part of the radial expansion tool section for expanding at least part of the completion tubular component, wherein the radial expansion tool section comprises a first element movable along the axial extension by the axial force generator and a support structure connected with the first element, the support structure supporting the completion tubular component during expansion, and the first element being connected with the support structure for moving the support structure at least partly radially outwards for simultaneous expanding the completion tubular component. The invention also relates to a downhole tool string comprising the wireline expansion tool and a driving unit, such as a downhole tractor, for propelling the wireline expansion tool forward in the well.

A control mechanism of a core drilling rig includes a central rod (14) and an outer barrel (23). The central rod (14) passes through, from the rear to the front, the inner cavities of a fluid channel activation module, an outer barrel unlocking module, a flow diverging module, and a coring barrel connecting module. The coring barrel connecting module comprises a core tube connecting pipe (62), a core ring bearing (63), a bearing inner ring (64), a ball A (6211) and a ball B (6411). The core tube connecting pipe (62) is connected at the front side thereof to the coring barrel (65). The bearing inner ring (64) is inside the core tube connecting pipe (62). The core ring bearing (63) is connected to an inner wall of the outer barrel (23).
