    Abstract: Apparatus and methods for selectively releasing a first wellbore componen t (30) to a second wellbore component (40) using a disconnect device. In one embodiment, the method includes coupling a disconnect device (20) to a work string (40) and a downhole tool (30); performing a downhole operation using the downhole tool, and selectively releasing an upper portion of the disconn ect device from a lower portion of the disconnect device, thereby releasing the downhole tool from the workstring. The method may also include reconnect ing the upper portion of the disconnect device to the lower portion of the d isconnect device. In one embodiment, the disconnect device is capable of tra nsferring torque to the wellbore component.

    IPC: E21B10/32

    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: SIGNAL OPERATED TOOLS FOR MILLING, DRILLING, AND/OR FISHING A disconnect tool (1000) for use in a string of tubulars, comprising: a tubular mandrel (1010) having a threaded inner surface; a tubular housing (1005) having a plurality of openings formed radially through a wall thereof; an arcuate dog (1015) disposed in each opening, each dog (1015) having an inclined inner surface and a portion of a thread (1065t) corresponding to the mandrel thread (1060t) and radially movable between an engaged position and a disengaged position, wherein each thread portion (1065t) engages the mandrel thread (1060t) in the engaged position, thereby longitudinally and rotationally coupling the housing (1005) and the mandrel (1010); a tubular (1040) sleeve longitudinally movable between a locked position and an unlocked position and having an inclined outer surface for engagement with the inclined inner surface of each dog (1015), wherein: the sleeve (1040) engages the dogs (1015) with the mandrel thread in the locked position, and the mandrel (1010), housing (1005), and sleeve (1040) define a flow bore through the disconnect tool (1000); a first (1078) spring biasing (1040) the sleeve toward the locked position; second springs (1082), each second spring biasing the respective dog (1015) toward the disengaged position; and an actuator (1075) comprising: a battery (314); a receiver (302) operable to receive an instruction signal; and a controller (310) operable to facilitate disengagement of the sleeve (1040) from the dogs (1015) in response to receipt of the instruction signal.
