  • Patent number: 8997850
    Abstract: An improved method and apparatus for dropping a ball, plug or dart during oil and gas well operations (e.g., cementing operations) employs a specially configured tool body assembly having valving members (e.g., safety or kelly values) and valving members holding plugs, balls, or darts to be dropped. In one embodiment, the ball(s), dart(s) or plug(s) are contained in a sliding sleeve that shifts position responsive to valve rotation. An optional indicator indicates to a user or operator that a ball or plug has passed a selected one of the valving members. A transmitter (or transceiver) provides an ability to generate a wireless signal that is received by receivers (or transceivers) on the tool body assembly. Each receiver (or transceiver) controls an electrical actuator that engages a valving member or the indicator. Wireless signals can be used to open or close a valve or to reset a “tripped” indicator.

  • Publication number: 20140367094
    Abstract: The present invention provides an apparatus and method for testing a wellbore, and to an apparatus and method to efficiently and effectively test the annular seal of a tubular string positioned within a wellbore. More specifically, the cement seal between a casing string and a wellbore is tested to assure there is no contamination of groundwater or between different geologic formations. An additional aspect of the present invention is to provide a testing assembly comprising a frangible body and a tool body, the tool body providing a passageway to the annular seal when the frangible body is drilled out. In one particular embodiment, the frangible body initially forms an encapsulated bore that aligns with the passageway.

  • Patent number: 8162047
    Abstract: An apparatus for reverse circulation cementing of surface casing in subterranean formations and associated methods are provided. One example of a method may involve a method of reverse circulation cementing a surface casing in a well bore with a conductor casing positioned therein comprising: providing a tool comprising at least one isolation device coupled to the surface casing; positioning the isolation device in the well bore to isolate an annulus between the surface casing and the conductor casing; flowing cement through a port in the conductor casing in a reverse circulation direction; and allowing the cement to set therein.

  • Patent number: 8127851
    Abstract: A system used to remove multiple isolation plugs from a wellbore. The system is efficient in fluidizing and circulating proppant located below an upper plug resting on top of proppant settled above a lower plug. The system uses a central port of the mill that is in communication with coiled tubing to fluidize and circulate the proppant around the perimeter of the upper plug. Once the proppant has been circulated from underneath the upper plug, the upper plug may mate and rotationally lock with a lower plug set within the wellbore. Upon locking, the system is able to rapidly mill out the upper plug and the lower plug until the lower plug is no longer set within the wellbore. The system provides for the rapid removal of multiple plugs positioned within a wellbore where an amount of proppant is present between the plugs.

  • Patent number: 8096357
    Abstract: The apparatus of the present invention provides a top drive supported tool for making up and running casing strings into a borehole. The tool comprises a fill-up and circulation assembly and a launcher assembly that is adapted to cooperate with a connectable cement wiper plug assembly for launching wiper plugs that control cement placement in the annulus between a casing string and a borehole containing the casing string. The tool of the present invention shortens or eliminates delays in well operations, thereby improving integrity of cement liners formed by placing cement slurry in a targeted interval.

  • Patent number: 8091628
    Abstract: Apparatus and methods for providing fluid and projectiles to downhole tubulars includes a manifold. The manifold may include a housing, a cartridge disposed within the housing, and an actuator. The cartridge includes multiple throughbores for selectively allowing a fluid flow to pass through, and storing a projectile. The actuator is adapted to move the multiple throughbores of the cartridge out of and into the fluid flow to release the stored projectile into the fluid flow. The manifold may include multiple projectiles that are stored laterally relative to each other for radial translation and release into the fluid flow.

    Abstract: A well head lubricator assembly including an elongated rigid tubular body defining an interior chamber open at a lower end to receive a plunger at a well head. The plunger is slidably positioned within the chamber in response to forces or loads acting thereon and has a seat arranged toward an upper end thereof. An upper end of the tubular body is closed. An axially elongated one-piece thermoplastic ether ester elastomer spring is slidingly positioned within the interior chamber of the tubular body. One end of the spring is seated on the seat of the plunger. The spring defines an elongated bore opening to opposed ends thereof. Moreover, the spring is provided with a plurality of axially spaced flange sections along a length thereof for guiding the spring for endwise sliding movement on an inside diameter of the tubular body. Any two flange sections on the spring are axially separated by an energy absorbing section for allowing the spring to react to energy imparted to the plunger.
