Abstract: Embodiments of the present invention generally relate to extendable cutting tools for use in a wellbore. 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: Apparatus and methods for selectively releasing a first wellbore component (30) to a second wellbore component (40) using a disconnect device. In one embodiment, the method includes coupling a disconnect device (20) to a workstring (40) and a downhole tool (30); 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. In one embodiment, the disconnect device is capable of transferring torque to the wellbore component.

Abstract: The present invention generally relates to methods and apparatus for subsea well intervention operations, including retrieval of a wellhead from a subsea well. In one aspect, a method of performing an operation in a subsea well is provided. The method comprising the step of positioning a tool proximate a subsea wellhead. The tool has at least one grip member and the tool is attached to a downhole assembly. The method also comprising the step of clamping the tool to the subsea wellhead by moving the at least one grip member into engagement with a profile on the subsea wellhead. The method further comprising the step of applying an upward force to the tool thereby enhancing the grip between the grip member and the profile on the subsea wellhead. Additionally, the method comprising the step of performing the operation in the subsea well by utilizing the downhole assembly. In another aspect, an apparatus for use in a subsea well is provided. In a further aspect, a method of cutting a casing string in a subsea well is provided.

Abstract: Embodiments of the present invention generally relate to signal operated tools for milling, drilling, and/or fishing operations. In one embodiment, a mud motor for use in a wellbore includes: a stator; a rotor, the stator and rotor operable to rotate the rotor in response to fluid pumped between the rotor and the stator; and a lock. The lock is operable to: rotationally couple the rotor to the stator in a locked position, receive an instruction signal from the surface, release the rotor in an unlocked position, and actuate from the locked position to the unlocked position in response to receiving the instruction signal.

Abstract: Oppfinnelsen viser en ledekildesammenstilling (100) for bruk ved forming av et. lateralt borehull fra et primært borehull. Ledekilesammenstillingen omfatter en hoveddel (122). og et bøyningsledd (120) over hoveddelen. Bøyningsleddet inkluderer en konkav del (111) for bøyning av en slipeborkrone i løpet av slipeoperasjon.Anordnet på en perforeringsplatedel (110) av den. konkave delen er en hevet overflateopsjon (116). Den opphøyde overflaten støtter en slipeborkrone over per-foreringsflatedelen i løpet av slipeoperasjonen. Dette vil igjen forhindre friksjonsmessig kontakt mellom slipeborkronen og perforeringsplatedelen i løpet av slipeoperasjon. Oppfinnelsen gir også en hittil ukjent metode for produsering av en ledekile hvor et hulrom er dannet bak perforeringsplaten ved å slipe ut baksiden av bøyningsleddet og deretter føye et annet bakre dekselledd til ledekiledelen for å fullføre sammenstillingen.
