Abstract: Apparatus and methods for selectively releasing a first wellbore component to a second wellbore component using a disconnect device. The method includes coupling a disconnect device to a workstring and a downhole tool; performing a downhole operation using the downhole tool, and selectively releasing an upper portion of the disconnect device from a lower portion of the disconnect device, thereby releasing the downhole tool from the workstring. The method may also include reconnecting the upper portion of the disconnect device to the lower portion of the disconnect device. The disconnect device is capable of transferring torque to the wellbore component.

Abstract: A method and apparatus for stabilizing a downhole tool during a downhole operation is described herein. The method and apparatus include a stabilizer having a stabilization member adapted to move between a retracted position and an extended position in order to engage a surface in a wellbore. The stabilizer also includes a plurality of actuators adapted to move the stabilization members from the retracted position to the extended position.

Abstract: Embodiments of the present invention generally relate to extendable cutting tools for use in a well bore. In one embodiment, a tool for use in a wellbore includes a tubular body having a bore therethrough, an opening through a wall thereof, and a connector at each longitudinal end thereof; and an arm. The arm is pivotally connected to a first piston and rotationally coupled to the body, is disposed in the opening in a retracted position, and is movable to an extended position where an outer surface of the arm extends outward past an outer surface of the body. The tool further includes the first piston. The first piston is disposed in the body bore, has a bore therethrough, and is operable to move the arm from the retracted position to the extended position in response to fluid pressure in the piston bore exceeding fluid pressure in the opening. The tool further includes a lock operable to retain the first piston in the retracted position; and a second piston operably coupled to the lock.

Abstract: A method for logging a downhole formation in a wellbore. The method comprises drilling a wellbore with a drill bit coupled to a disconnect device (20). The disconnect device is then actuated to detach the drill bit from a portion of a conveyance (40). A logging operation is then performed between two portions of the disconnect device. The disconnect device may then be reattached.

Abstract: A stabiliser tool 112 which is coupled to a downhole tool includes extendable stabiliser members 118 possibly in the form of rollers that are extended along an axis 208 which is offset from the radius of the stabiliser tool body 112. Extension can be the result of hydraulic pressure acting on a piston arrangement 206, 209. Extension of the stabiliser members 118 can be compliant to allow for different diameters of the wellbore or casing as the stabiliser tool moves through the wellbore or casing.

Abstract: A method of re-entering a primary wellbore10 from a lateral wellbore 20 after a lateral wellbore has been completed comprises the steps of locating a cutting device (210 figure 3) such as a milling bit adjacent a tubular such as a liner 28 within a wellbore, rotating the milling bit whilst maintaining an axial position of the milling bit relative to the liner to initiate an opening18, and rotating and axially advancing the milling bit to complete the opening. Included is an embodiment relating to a method of removing a portion of a liner at an intersection of a lateral wellbore as well as an embodiment relating to a bottom hole assembly (200 figure 3) comprising a drill collar (230 figure 3), a sub (220, 220 figure 3) connected to the drill collar and a lead mill (210 figure 3).
