Abstract: The present invention generally relates to an apparatus and method of jarring with an overpull generator. In one aspect, a method of dislodging an object stuck in a wellbore is provided. The method includes the step of running an assembly into the wellbore on a conveyance member and attaching the assembly to the object, wherein the assembly comprises an overpull generator and a delay force release device. The method also includes the step of generating an overpull force in the wellbore by selectively activating the overpull generator. Additionally, the method includes the step of applying an impact force to the object by activating the delay force release device and releasing the generated overpull force, thereby dislodging the object stuck in the wellbore. In a further aspect, an assembly for dislodging an object stuck in a wellbore is provided. In yet a further aspect, an overpull generator for use in generating an overpull force in a wellbore is provided. 2$ /7 7 o >7 2$ >7/> K 2$ >7 2$ >7 >7 2$7 ~K Cl oK/S 0 /7 7 4(1

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 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.
