Patent number: 10619428Abstract: A connection assembly for automated lifting and positioning of a chiksan or other fluid conduit in proximity to a fluid inlet of a device such as, for example, a cement or hydraulic fracturing head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet including, without limitation, when the device is positioned at an elevated location above a rig floor.Type: GrantFiled: July 9, 2018Date of Patent: April 14, 2020Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D. Robichaux, James G. Martens, John E. Hebert, Juan Carlos E. Mondelli, James Champagne, Joseph Boudreaux, Scottie J. Scott, Jeremy LeCompte

Patent number: 10570675Abstract: A centralizer assembly installed on a casing section. A bow spring assembly having bow spring members is installed around the outer surface of the casing section and can rotate about the outer surface of the casing section. A portion of the casing section that is aligned with the bow spring assembly is swaged to increase the outer diameter of that section. Bow spring heel supports prevent bow spring members from contacting the outer surface of the central casing section when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles.Type: GrantFiled: January 6, 2017Date of Patent: February 25, 2020Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D.

Patent number: 9683437Abstract: An electro-mechanical indicator system for signaling when a droppable object (such as, for example, a dart, plug or ball) is released during well cementing operations. A body section has first and second chambers divided by a fluid and pressure sealing barrier. A mechanical trigger mechanism is situated in the first chamber, which is exposed to elevated pressures and harsh wellbore fluids. Less robust components, such as sensor(s), power source(s), and signal device(s) located in the second chamber, remain isolated from the wellbore environment and elevated pressures.Type: GrantFiled: September 10, 2014Date of Patent: June 20, 2017Assignee: Blackhawk Specialty Tools, LLCInventors: Kenneth Flanigan, James F. Giebeler, Juan Carlos E. Mondelli, Ron D. Robichaux

Patent number: 9677351Abstract: An anchor assembly for anchoring casing or other pipe against axial upward movement while permitting rotation of the casing or other pipe. An inner mandrel member has a central bore and a flange member extending around the outer circumference of the mandrel. A friction reducing ring member is located on an upper surface of the flange member, while layered friction reducing sleeve members are positioned around the outer surface of the mandrel member. An anchor sleeve member is concentrically and rotatably positioned around the outer surface of the outermost friction reducing sleeve member. Connection flanges, each having at least one bore for attachment to a shackle or other connecting device, extend laterally from the outer periphery of the anchor sleeve member and allow for anchoring of the assembly (and any attached casing or other pipe) to a rig or other structural support member.Type: GrantFiled: September 18, 2013Date of Patent: June 13, 2017Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D. Robichaux, Thad Scott, James G. Martens, J. Christopher Jordan, Jr.

Patent number: 9605505Abstract: A remotely operated lifting top drive cement head has a high tensile strength and the ability to swivel or rotate. The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be launched as desired. The cement head can be remotely operated without requiring personnel to be lifted off the rig floor to actuate the tool or observe tool status.Type: GrantFiled: December 7, 2015Date of Patent: March 28, 2017Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D. Robichaux, James F. Giebeler, Juan Carlos E. Mondelli

Patent number: 9500060Abstract: A remotely operated lifting top drive cement head is provided having a high tensile strength, as well as the ability to swivel or rotate about a central vertical axis. The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be beneficially launched into said slurry flow at desired point(s) during the cementing process. The internal components of the cement head can be easily accessed using interrupted thread connections that can be quickly and easy connected and disconnected in the field without requiring specialized equipment. The cement head can be rigged up and remotely operated without requiring the lifting of personnel off the rig floor to actuate the tool or observe tool status.Type: GrantFiled: January 23, 2014Date of Patent: November 22, 2016Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D. Robichaux, James F. Giebeler, Juan Carlos E. Mondelli

Patent number: 9488032Abstract: An apparatus for retaining and securing elevated objects such as cement valves. A harness member is wrapped around the outer surface of an elevated object, and adjustable straps are tightened to secure the harness member in place. An elongate sling member, attached the harness member, is securely attached to a cement head assembly or other nearby support structure. The apparatus provides positive retention should an elevated object become detached, thereby preventing the object from falling and injuring personnel or damaging property.Type: GrantFiled: April 11, 2014Date of Patent: November 8, 2016Assignee: Blackhawk Specialty Tools, LLCInventors: Ron D. Robichaux, Bobby L. Brown

Patent number: 9328585Abstract: An auto-fill type float collar assembly is provided. The float collar assembly of the present invention has at least one curved flapper-style valve, preferably constructed of composite, non-metallic material. Each flapper of the present invention has a substantially 90° range of motion, and is closed via a torsion spring. Each flapper is held in the open (or “auto-fill”), position via an external shifting mechanism passing around, rather than through, the central flow bore of the assembly. A floatable actuation ball can be run with the tool, or pumped downhole, in order to selectively actuate the assembly and close the flappers when desired.Type: GrantFiled: January 12, 2015Date of Patent: May 3, 2016Assignee: Blackhawk Specialty Tools, LLCInventors: Brad Groesbeck, Jeffrey Arcement, J. Christopher Jordan, James G. Martens

Patent number: 9297218Abstract: A centralizer assembly having a tubular body member with upper and lower channels extending around the external surface of said central tubular body member. A bow spring assembly having bow spring members is installed around the outer surface of the tubular body member and can rotate about the outer surface of the central tubular body member. Bow spring heel supports prevent the bow spring members from contacting the outer surface of the central tubular member when compressed. Non-abrasive materials prevent damage to wellhead or other polished bore receptacles. A robust bolster frame protects the centralizer assembly during shipping, storage or other periods of non-use.Type: GrantFiled: August 10, 2015Date of Patent: March 29, 2016Assignee: Blackhawk Specialty Tools, LLCInventors: J. Christopher Jordan, James G. Martens, Jeffrey J. Arcement, Juan Carlos E. Mondelli, John E. Hebert, Scottie J. Scott, Thomas A. Dupre′
