Publication number: 20230392466Abstract: A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. The subsea wellhead assembly may include a tubing hanger positioned in or below a wellhead housing coupled to a subsea well, a tree cap fluidly coupled to the tubing hanger and disposed atop the wellhead housing, and a pair of master production valves configured to be selectively actuated from an open position to a closed position to shut in the subsea well, each of the pair of master production valves located within or below the wellhead housing.Type: ApplicationFiled: August 22, 2023Publication date: December 7, 2023Inventors: Chris D. Bartlett, Daniel J. McLaughlin, Raymond A. Guillory, Blake T. DeBerry, Marcus Smedley, Gregory K. Norwood, David A. Scantlebury, Andrew B. Mitchell, Darren W. Mills

Patent number: 11542778Abstract: A subsea wellhead assembly having an arrangement of primary well barriers provided in equipment that is located within the well and/or the wellhead housing is provided. All of the well barriers may be located within the tubing hanger and/or the production tubing string extending into the wellbore. The subsea wellhead assembly also includes a flowline connection body placed atop the wellhead housing and fluidly coupled to the tubing hanger. None of the primary barriers for the well are located in the flowline connection body.Type: GrantFiled: December 4, 2019Date of Patent: January 3, 2023Assignee: Dril-Quip, Inc.Inventors: Chris D. Bartlett, Daniel J. McLaughlin, Raymond Guillory, Blake T. DeBerry, Marcus Smedley

Patent number: 7008141Abstract: Expandable and contractible buoyancy modules are assembled to the risers of a deepwater exploration spar or other offshore structure to provide an upwardly directed buoyancy force to offset at least a portion of the weight of the riser. The buoyancy modules have a fabricated pressure tight expandable and contractible envelope composed of rubber or rubber-like material which is mounted onto a tubular member having a central passage for receiving the riser to be supported. The tubular member projects beyond the respective upper and lower ends of the envelope and defines upper and lower riser joint connectors and buoyancy module travel stops which secure the buoyancy module to the riser and provide for force transmission from the buoyancy module to selected locations along the length of the riser or to the upper end of the riser.Type: GrantFiled: December 4, 2000Date of Patent: March 7, 2006Assignee: FMC Technologies, Inc.Inventors: John A. Fitzgerald, Marcus A. Smedley, Harold B. Skeels, Christopher E. Cunninham

Patent number: 6640902Abstract: A wellhead system for petroleum producing wells comprises a “stack-down” casing hanger configuration. In this stack-down system, the hanger for each successively smaller diameter casing string is landed or “nested” within the hanger for the next larger casing string. This approach allows the pack-off for each casing hanger to be retrieved independently, thus allowing fluid communication to be established with any of the casing annuli after all of the casing strings and hangers have been installed. Thus the pressure in each annulus may be monitored while the well is in production mode.Type: GrantFiled: April 17, 2002Date of Patent: November 4, 2003Assignee: FMC Technologies, Inc.Inventors: Robert B. Baten, Harold B. Skeels, David MacFarlane, Russell E. McBeth, Randy J. Wester, Marcus A. Smedley

Patent number: 6557638Abstract: The concentric tubing completion system of the present invention comprises a surface Christmas tree which is located on a surface structure, a tieback connector which is secured to a mudline wellhead that is installed at the upper end of a subsea well bore, a mudline tubing hanger which is supported in the tieback connector, and a pair of concentric tubing strings which are suspended from corresponding tubing hangers in the surface Christmas tree and connected to the mudline tubing hanger. The annulus between the concentric tubing strings communicates with a number of passages in the mudline tubing hanger which are connected to the tubing annulus below the mudline tubing hanger. Thus, lift gas or other fluids may be communicated between the surface christmas tree and the tubing annulus through this annulus between the concentric tubing strings.Type: GrantFiled: September 14, 2001Date of Patent: May 6, 2003Assignee: FMC Technologies, Inc.Inventors: Christopher E. Cunningham, Christopher D. Bartlett, Marcus A. Smedley, Russell E. McBeth, Robert B. Baten
