Abstract: An actuator and method for setting a subterranean tool uses an externally mounted actuator on a tubular string that is operably engaged to the tool to be actuated. At the desired location for actuation a signal is given to a valve assembly. The opening of the valve releases the pressurized compressible fluid against a floating piston. The piston drives viscous fluid ahead of itself through the now open valve that in turn drives an actuating piston whose movement sets the tool. The triggering mechanism to open the valve can be a variety of methods including an acoustic signal, a vibration signal, a change in magnetic field, or elastic deformation of the tubular wall adjacent the valve assembly.

Abstract: The tubular string to be expanded is run in on a running string. The swage assembly has a seal from the running string to the existing tubular and the top of the tubular string to be expanded also has a similar seal against the exiting tubular. Annulus pressure around the running string drives the swage assembly to support the expanded tubular to the exiting tubular and to continue expansion to the end of the tubular. Cementing then takes place followed by reconfiguring the swage assembly to engage the liner hanger seal with the result being a monobore connection in a single trip including the cementing.

Abstract: A string to be expanded is run in with a running string that supports a swage assembly. The running string is secured to the existing tubular and the top of the string to be expanded is sealed around the supported running string. The pressure applied to the annular space above the seal drives the liner over the swage. A cement shoe is affixed to the lower end of the string that is expanded after becoming detached from the running string assembly. When the expanded liner bottoms on a support, generally the hole bottom, the cement is delivered through the shoe and the expansion of the top of the string into a recess of the string above continues. The swage assembly with the seal and the anchor are then recovered as the running string is removed during the process of expanding the top of the expanded string into the lower end recess of the existing string already in the wellbore.

Abstract: In aspects, the present disclosure provides a monobore wellbore construction apparatus and method, which in one embodiment may include a series of overlapping expandable liner sections. In one aspect, the overlapping liner sections may be expanded and pressed to provide no gaps along the length of the liner system. In another aspect, the liner sections may include centralizers and/or circumferential seals that provide sealing functions and spaces between the overlapping liner sections. The liner sections may be lined with a suitable sealing material, including an epoxy or may be filled with cement or another desired materials.

Abstract: The expandable casing packing element systems for cased and open-hole wellbores include an expandable casing member having a sealing device comprising a sealing element disposed between at least two retainer rings. The retainer rings have flat cross-sections and the sealing element is forced radially outward by the expansion of the expandable casing against the two retainer rings such that the sealing element protrudes outwardly beyond the retainer rings and engages the wall of a wellbore in three locations. The retainer rings can also include flares that extend outwardly from the body of the expandable casing to which they are attached. As the expandable casing is expanded, the flares are forced inward to compress the sealing element which is then extruded radially outward through a gap between the two retainer rings to engage and seal off the wellbore.

Abstract: An apparatus for identifying oilfield tubular assets. A ring having an inner diameter is supported within the inner diameter of the tubular asset so that the inner diameter of the ring is substantially flush with the inner diameter of the tubular asset. At least one electronic circuit supported by the ring and adapted to transmit a unique identification code to a portable receiver. The portable receiver may have a display to communicate identity of the tubular asset. The portable receiver may display tubular asset maintenance and usage records stored at a central location or at the electronic circuit.

Abstract: A trans-axial cutting apparatus used for cutting an inner surface of an opening formed within an object and accessible from outside the object. The apparatus comprises an elongate portable frame. The frame supports a cutting member on the first side and a stabilizing member on the second side. The stabilizing member is adapted to secure the apparatus during operation of the cutting member. The apparatus may be used to cut a counter bore, a longitudinal slot or groove at a desired depth, a helical slot or groove at a desired depth, or a slot or groove at a desired depth and along a desired path within the opening. Additionally, the apparatus is adapted to make any of the preceding cuts in a tapered or stepped manner within the opening of the object.
