  • Patent number: 10267111
    Abstract: Dual section mills are selectively sequentially operated by locking an actuator for the backup mill as the primary mill has blades extended with internal flow through a housing. When the primary mill is spent the support string is shifted to defeat a lock on an actuation piston for the backup mill so that its blades can extend and continue to mill to finish the job. The blades of the primary mill continue to rotate in the already milled portion of the window as the secondary mill enlarges the window. Another way the secondary mill is actuated is to open access to flow to the secondary mill by removing a pressure barrier such as a valve or a disappearing plug, for example.

  • Patent number: 10161209
    Abstract: The present invention provides a section mill/casing cutter/stabilizer apparatus and method featuring a segmented body that allows different pressure actuated sequences of extending stabilizer blades and cutting blades to cause the cutting and milling of wellbore casing and other debris in a wellbore. Applied pressure results in the flow through a flow restriction that creates a force on return springs associated with the centering and the cutting blades. The segmented body allows the manipulation of the blades and centralizers as needed. The spring returns a mandrel to the original retracted or run-in position on cessation or reduction of flow. The ability to vary the segments and sequences makes it easier to run the apparatus in conjunction with other milling and cutting tools, enhancing their performance through centralization and enlarging of cutting capacity.

  • Patent number: 10081996
    Abstract: In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.

  • Patent number: 9725977
    Abstract: Cutter blades extend and stay extended as long as pressure on a piston is continued. The blades either open fully in open hole or cut through the wall of a tubular and then mill in an uphole direction to take out a piece of the tubular. The piston that held out the blades when pressure was applied is acted on by a return bias when the pressure is removed so that the blades can retract and the tool removed through the cut tubular. As a backup a plug can be dropped to obstruct a through passage in the piston so that pressure from the surface can be used to force the piston back to retract the blades. Continued drilling operations or the cut and milled portion can be then blocked off such as with cement for a plug and abandonment of the well.

    Abstract: Methods and apparatus, for performing rotary, cutting and/or crushing operations in a subterranean borehole or conduit thereof, which use higher and lower pressures therein to operate a motor, actuator and/or piston, particularly for sealing operations using a downhole assembly, placeable with a cable. The downhole assembly comprises at least a motor or actuator coupled to at least one of a rotary tool, axial cutting tool and/or packer or piston. The motor or actuator piston may be operated by differential fluid pressure across ends thereof, to form a space free of debris that may be provided for placement of a settable sealing material to prevent leakage paths in the concrete seal of said subterranean borehole or conduits thereof.

  • Patent number: 7918280
    Abstract: A communication tool apparatus is described which is adapted to provide selective communication of control fluid through a downhole tool, such as a safety valve. The downhole safety valve is a tubing retrievable subsurface safety valve (“TRSSSV”). The communication tool may be run downhole and within the TRSSSV. Once within the TRSSSV, the communication tool apparatus activates a cutting device within the TRSSSV such that communication of control fluid through the TRSSSV is possible. A replacement safety valve run on a wireline may then be inserted into the TRSSSV and be operated via the control fluid line, as a new communication path created by the communication tool described herein. A method of using the communication tool apparatus is also described.

  • Patent number: 7909100
    Abstract: Casing cutter for severing multiple tubulars in a well bore has a pair of cutter blades pivotally mounted on a support body. The blades are pivotally mounted for gradual movement outside of the support body when downward force is applied to proximate ends of the cutter blades. The support body is rotated inside the innermost of the multiple tubulars, while the cutter blades sever the tubulars of progressively increasing diameter. Should the cutter blades or pivotal connections become unusable, the tool body can be rotated about the vertical axis and secured to a downhole string by the opposite end. A substitute pair of cutter blades are then engaged on the tool body and operated to cut the casings similar to the first set of the cutter blades.

    Abstract: Embodiments of the present invention generally relate to a method and/or apparatus for deploying wireline tools with a non-electric string. In one embodiment, a method of determining a free point of a tubular string stuck in a wellbore includes deploying a tool string in the stuck tubular with a non-electric string. The free point assembly includes a battery, a controller, and a free point tool. The method further includes activating the free point tool by the controller. The free point tool contacts an inner surface of the stuck tubular string. The method further includes applying a tensile force and/or torque to the stuck tubular string; and measuring a response of the tubular string with the free point tool.

  • Patent number: 7861783
    Abstract: A method for adapting a tubular element extending into a wellbore formed in an earth formation, where the tubular element is susceptible to damage caused by axially compressive forces acting on the tubular element as a result of compaction of the earth formation surrounding the tubular element. The method comprises the steps of reducing the axial stiffness of at least one section of the tubular element, and allowing each tubular element section of reduced axial stiffness to be axially compressed by the action of said axially compressive forces, thereby accommodating compaction of the earth formation surrounding the tubular element.

  • Patent number: 7708077
    Abstract: A bottom hole assembly in a casing-while-drilling operation is retrieved attaching a wireline to the bottom hole assembly. The density of the fluid in the casing string is lightened to a lesser density than the fluid in the annulus, thereby creating a pressure differential between fluid above the bottom hole assembly and fluid below the bottom hole assembly to exert an upward force on the bottom hole assembly. The operator pulls upward on the wireline to assist the upward force in moving the bottom hole assembly up the casing string.
