A workstring apparatus for creating an annular seal in a wellbore is described. Workstring comprises at least one packer apparatus comprising a body portion and an elastomeric packer element which is deformable into an outwardly deployed condition to deform wellbore casing. A fluid accumulator is provided to hold fluid to actuate at least one hydraulic cylinder of the packer apparatus. An electrically powered pump is operable to pump fluid from accumulator into the hydraulic cylinders of packer apparatus to deform the elastomeric packer element outwardly. A wireline connects the workstring to the surface and provides electrical power to the workstring. Wireline may be an electrical feed such as a composite rod or e-coil.

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 force setting apparatus comprises a valve manifold forming a plurality of ports and a rotary valve coupled to the valve manifold and rotatable on the valve manifold. The plurality of ports are in fluid communication with a plurality of pistons. The rotary valve is coupled to an air chamber that used to transfer low pressurized oil coming from the pistons and out of the ports. The valve is rotatable to uncover the plurality of ports and allow high pressurized oil to flow through a plurality of pistons and out of the plurality of ports. The valve is rotatable to cover the plurality of ports and allow low pressurized oil to flow through the valve and out of the air chamber.

A downhole vibration tool includes a body, a mandrel, a spring, and a balance piston. The body may be generally tubular and may have one or more helical slots formed on an inner surface thereof. The mandrel may be generally tubular, may have a bore, and may be positioned at least partially within the body. The mandrel may have one or more helical splines formed on an outer surface of the mandrel, the helical splines engaging the helical slots of the body such that the mandrel is translatable axially relative to the body. The spring may be positioned in an annular space formed between the mandrel and the body defined as a spring chamber. The balance piston may be in an annular space formed between the mandrel and the body, wherein the balance piston separates an oil-filled chamber from an internal pressure chamber.

A method of separating a downhole tubular includes running a tool into a wellbore to a predetermined location on a work string and actuating flow actuated slips. The method also includes maintaining slips in a set position by providing a first upward force on the work string. The method further includes rotating the work string to separate an upper portion of the tubular from a lower portion using a cutter assembly disposed on the work string below the slips and pulling the upper portion of the tubing and the tool from the wellbore.

A method and apparatus for a locking system for a downhole tool. The locking system includes a first portion having a plurality of displaceable members, a second portion disposed around the first portion; a locked position wherein axial movement between the members is prevented; and an unlocked position wherein axial movement between the members is permitted.

An activation control module utilizes gravity and/or centrifugal acceleration to move a mechanical element that controls, activates or deactivates a mechanical or hydraulic mechanism, for use with a downhole tool such as a drilling tool or reamer in a wellbore. In embodiments, the activation control module described herein may utilize a combination of centrifugal acceleration and/or gravity due to an inclination of the downhole tool to move a valve, which turns off pressure to a hydro-mechanical system. The activation control modules may be utilized in applications where very little space is available for larger mechanisms. Further, the activation control modules do not require expensive and complex electro-mechanical systems, reducing or eliminating the need for batteries, wiring, electronics, motors, pumps and the like. Moreover, the activation control modules described herein do not require the use of a turbine, a centrifugal clutch or a linear actuator.

Certain aspects and features of the disclosure relate to a hydraulic connector for use in a wellbore, for example, with or as part of a disconnect tool. The hydraulic connector can isolate hydraulic fluids in upper and lower hydraulic lines using hydraulic pistons. The pistons in the upper and lower parts of the hydraulic connector interconnect mechanically when the connector is engaged and communicate pressure without transferring hydraulic fluid across the interface. The hydraulic fluid can therefore remain confined within the upper and lower hydraulic lines even when the disconnect tool is disengaged, reducing or eliminating incidents of hydraulic fluid leaking or spilling into the wellbore.
