Patent number: 10006256Abstract: Provided is a safety joint with a moveable seal designed to prevent hydrostatic locking. The safety joint is primarily made up assembling a pin end having a first seal, a threaded connection, and a second, moveable seal to a box end. The moveable seal is disposed in a recess formed in the pin end and includes an O-ring and a spring. When the safety joint is assembled downhole, a volume of fluid may become trapped between the first seal and the second seal. The trapped fluid in turn pushes the O-ring towards the spring, thereby limiting pressure build-up by substantially maintaining the volume trapped between the first and second seals.Type: GrantFiled: November 19, 2015Date of Patent: June 26, 2018Assignee: National Oilwell Varco, LLPInventors: James R. Streater, Jr., Daniel Hernandez, Jr., Josefat Rodriguez-Estrada, Jr., Francisco Tejada, Jr.

Patent number: 9212530Abstract: A grapple for use in an overshot has a tension ring with a reduced helix diameter. However, the helix diameter is not reduced on either sides of the control finger slot to allow the grapple to remain in contact with the control. In the alternative, a composite helix member may be utilized. Another embodiment comprises the inclusion of expansion blades on the inner diameter (“ID”) of the tension ring which allow the grapple to expand substantially before the fish reaches the segments. Another embodiment provides for a control with an offset finger to allow the guide thread ID to be smaller than the bowl helix major ID. Yet another embodiment provides a spiral grapple having grooves along its axis to provide the ability to catch a larger range of fish.Type: GrantFiled: November 15, 2010Date of Patent: December 15, 2015Assignee: NATIONAL OILWELL VARCO, L.P.Inventors: James R. Streater, Jr., Daniel Hernandez, Jr., Jose Saldana

One embodiment includes expansion blades on the inner diameter (“ID”) of the tension ring to allow the grapple to expand substantially before the fish reaches the segments. An embodiment provides for a control with an offset finger to allow the guide thread ID to be smaller than the bowl helix major ID. Also provided is grapple control for a spiral grapple that has at least one gap to allow the grapple control to be more compliant during fishing operations. The control may include one or more bridges of reduced thickness. Alternate embodiments include gaps and support bands with or without bridges and/or a backup ring to help eliminate misalignment of the grapple control with the support shoulder of the overshot guide.Type: GrantFiled: November 7, 2013Date of Patent: December 1, 2015Assignee: NATIONAL OILWELL VARCO, L.P.Inventors: James R.

Patent number: 7665927Abstract: The present invention is an improved swivel joint for use as part of a cable-guided fishing assembly. The swivel joint contains a bearing assembly comprising a series of ball bearings partially encased by an inner and outer race. During a cable-guided fishing operation, the inner and outer race exert a shearing, rather than compression, force on the ball bearing due to the unique configuration of the bearing assembly. This unique configuration increases the strength of the bearing assembly, and the corresponding strength of the swivel joint, without necessitating an increase in the outer diameter of the swivel joint.Type: GrantFiled: September 1, 2005Date of Patent: February 23, 2010Assignee: National-Oilwell DHT, L.P.Inventors: Gregg A. Bosley, Aditya V. Soman, David P. Ross, James R. Streater, Jr.
