Abstract: The present invention generally relates to a pipe handling system for use with a tubular joining system (such as a welding or forging assembly) located on a drilling rig at a wellbore. In one aspect, a method of forming a string of pipe using a joining assembly at a wellbore is provided. The joining assembly includes an internal joining tool and an external joining tool. The method includes the step of picking up the pipe joint using an elevator. The method further includes the step of positioning a lower end of the pipe joint adjacent an end of a string of pipe disposed in the external joining tool. The method also includes the step of moving the internal joining tool from a first position to a second position relative to the elevator, wherein the second position is between the pipe joint and the string of pipe. The method further includes the step of forming a connection between the pipe joint and the string of pipe. The method further includes the step of gripping the pipe joint with a gripping tool and releasing the elevator from the pipe joint. Additionally, the method includes the step of lowering the pipe joint and the string of pipe into the wellbore. In another aspect, a method of forming a string of pipe using a joining assembly on a rig is provided. In a further aspect, a pipe handling system for locating a pipe joint in a joining assembly that includes an internal joining tool and an external joining tool is provided.

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: The present invention provides methods and apparatus for determining the location of an apparatus in a wellbore. The method includes lowering the apparatus with a conveying member and measuring a parameter associated with the conveying member. Thereafter, the measured parameter is used to determin e the location of the apparatus as well as other conditions in the wellbore. T he apparatus includes a conveying member operatively connected to an object released downhole. The apparatus may also include a dispensing apparatus coupled to one end of the conveying member. Preferably, the conveying member is a fiber optics line capable of transmitting optical signals. Other types of conveying members include a wire, a tube, and a cable. Additionally, a senso r may be disposed on the object and connected to the conveying member.

Abstract: A downhole apparatus comprises a plurality of tubing sections. Each tubing section has substantially cylindrical end portions initially of a first diameter for coupling to end portions of adjacent tubing sections. The end portions are expandable to a larger second diameter. Each tubing section als o has an intermediate folded wall portions initially in a folded configuration . The intermediate folded wall portions are unfoldable to define a substantial ly cylindrical form of a third diameter.
