The anvil member and the sealing member are moveable relative to one another when the moveable member is moving from the open to the closed configuration. During opening and closing the sealing member is displaced away from the cutting device as the cutting device engages the anvil member. The sealing member is pushed away from the moveable member and the anvil to a maximum separation from the movable member at the point on the stroke when the cutting surface of the moveable member is moving past the anvil member. | ||||||

| 156 | Severing of downhole tubing with associated cable | US12055434 | 2008-03-26 | US08020619B1 | 2011-09-20 | Michael C. Robertson; William Boelte |
| Methods for severing tubing having a cable extending along its length include lowering a first cutting torch into the tubing to a desired location, igniting the first cutting torch, and directing cutting fluids in a circumferential arc to form a first cut in the tubing and sever the cable. A second cutting torch can be lowered and positioned relative to the first cut, and ignited to direct cutting fluids radially to cut the tubing all around the circumference, enabling retrieval of the tubing. The need for precise positioning and alignment of the torches to sever both the cable and tubing is thereby eliminated. | ||||||

| 158 | Auxiliary Conduit Cutting Apparatus | US12651132 | 2009-12-31 | US20100294478A1 | 2010-11-25 | Christopher W. Guidry; Anthony C. Zavesky; Joshua C. Joerg |
| A cutting assembly for external conduits on a tubing string or main tubular conduit features at least one breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing that is integral with a passage having threaded end connections. While in some scenarios it is preferred that the main tubular conduit is severed below the cutting assembly thus allowing the cutting apparatus to be retrieved with the upper portions of the cut main tubular conduit and external longitudinal member(s), in other circumstances it may be desired that the main tubular conduit is severed above the cutting assembly allowing the cutting apparatus to be left “downhole” with the lower portion of the cut main tubular conduit and the BHA. The cutter knife assembly chambers or channels can be in banks that are axially spaced using bypass channels to access lower banks. The cutter knife assembly and associated channels can be mirror images so that the external conduits can be cut regardless of where the tubing string is severed and one or more conduits can be cut with a single cutter assembly. | ||||||
| 159 | Auxiliary Conduit Cutting Apparatus | US12469388 | 2009-05-20 | US20100294477A1 | 2010-11-25 | Anthony C. Zavesky; Steven G. Blair; Christopher W. Guidry; Steve Rosenblatt |
| A cutting assembly for external conduits on a tubing string features a breakaway in the string that can be severed with a tensile force. Preferably each external conduit is run through a cutter housing. Upon severing of the string and applying a pickup force, a tension is applied to each external conduit since the severing of the string happens above all the cutter housings. Each housing cuts at least one conduit and the upper portion of the string brings with it the upper portion of the external conduit while the lower portions of each cut external conduit are retained in the cutter housings that remain downhole below the breakaway. In that manner there are no loose external conduit ends to interfere with and/or disturb subsequent fishing or other wellbore operations. | ||||||

| A wireline cutter comprises a primary housing with a first axial bore configured to receive a wireline positioned within a well bore, and a first blade mounted within the primary housing and operable to cut the wireline. A method of cutting a wireline in a well bore comprises running a wireline cutter into the well bore, receiving the wireline within the wireline cutter, and cutting the wireline with the wireline cutter. A one-trip cutting system for use in a well bore comprises a wireline cutter, and a coiled tubing cutter. A method for cutting a coiled tubing with a wireline disposed therein comprises running a system comprising a wireline cutter and a coiled tubing cutter into the well bore, cutting the coiled tubing with the coiled tubing cutter, and cutting the wireline with the wireline cutter, wherein both cutting steps are performed in one trip into the well bore. | ||||||
