Patent number: 7073591Abstract: A subsea wellhead assembly has the capabilities of communicating from a tree assembly mounted on an inner wellhead housing to a casing annulus. A passage in the wellhead assembly extends within the bore of the wellhead housing from the casing annulus to the tree assembly. A portion of the passage is located within a casing hanger. The passage is opened and closed by a valve. The valve does not open the passage until the tree assembly is connected to the wellhead housing and a tubing hanger orientation sleeve lands in the wellhead assembly. The tubing hanger orientation sleeve actuates the valve when it lands to open the passage. When the passage is opened, the casing annulus is in fluid communication with the interior surface of the wellhead housing, which is in communication with the tree assembly.Type: GrantFiled: January 5, 2005Date of Patent: July 11, 2006Assignee: Vetco Gray Inc.Inventors: Alfred Massie, Harry A. Moore, Richard Lovell, Kevin G. Buckle, John H. Osborne

Patent number: 6705401Abstract: A susbsea well has communication passages to enable annulus pressure surrounding inner and intermediate strings of casings to be monitored at the surface. The passages both have outlets that allow communication to the tree assembly for monitoring. In one embodiment, the passage outlets are located in the bore of the high pressure well head housing and communicates to the tree assembly along an isolation sleeve. In another embodiment, the passage outlets are located on the exterior of the high pressure wellhead housing and communicate through a flying lead coming down from the tree. In another embodiment, the passage outlets are located on the exterior of the high pressure wellhead housing and communicate to an upward facing connection which is stabbed with a downward facing connection coming down from the tree.Type: GrantFiled: January 4, 2002Date of Patent: March 16, 2004Assignee: ABB Vetco Gray Inc.Inventors: Kevin G. Buckle, John H. Osborne, Bernard Humprey, Alan M. Clark, Alfred Massie

Patent number: 6698520Abstract: A subsea well apparatus has features for controlling and monitoring production fluid flow from a well. A christmas tree lands on a subsea wellhead, the tree having a tubular, open upper end. A first flow passage extends from a lower end of the tree to the upper end for communicating fluid with the well. A second flow passage extends downward from the upper end of the tree and has an outlet on a sidewall of the tree for communicating with a flowline. A production module lands on and is retrievable from the upper end of the tree, the module having a flow loop with one end in communication with the first flow passage and another end in communication with the second flow passage. At least one flow interface device is located in the loop of the production module. The flow interface device may be used to monitor or control the flow and may be a temperature or pressure sensor, a flow or multi-phase flow meter, or a choke.Type: GrantFiled: September 30, 2002Date of Patent: March 2, 2004Assignee: ABB Vetco Gray Inc.Inventors: Stephen P. Fenton, John H. Osborne, Rolf Nordaunet

Patent number: 5503230Abstract: A subsea well assembly has guides for orienting electrical connectors located on a concentric tubing hanger and on the tree. The guides use a guide slot and key to rotate the electrical connectors on the lower end of the tree when the tree is installed on the wellhead. The tree electrical connectors are located on the upper guide member and rotate relative to the tree as the guide slot engages the guide key. An annulus valve in the tubing hanger uses a sleeve with inner and outer metal seal lips.Type: GrantFiled: November 17, 1994Date of Patent: April 2, 1996Assignee: Vetco Gray Inc.Inventors: John H. Osborne, Brett R. McConaughy, Robert O. Lilley, Norman Brammer, Kenneth C. Davidson
