Patent number: 7931306Abstract: A vented gas riser for use in a system for conducting pressurized gas through a gas carrier pipe from a gas supply source line located below ground level to a delivery point disposed above ground is provided. A fluid tight gas riser protective casing is disposed around said carrier pipe and creates a gas escape passageway in an elongate annular space between the carrier pipe and the casing. Any gas which leaks from the gas carrier pipe is captured in the gas escape passageway. A riser transition head, which includes at least one vent passageway, provides a fluid connection with said gas escape passageway and with the atmosphere such that any gas which leaks in the vicinity of the gas escape passageway can escape through the at least one vent into the atmosphere.Type: GrantFiled: May 11, 2010Date of Patent: April 26, 2011Assignee: Energy Control Systems, Inc.Inventors: James M. Royston, John A. Samudovsky

Publication number: 20100276156Abstract: A technique is provided for installing a tubular hanger and tubular hanger seal in a wellhead. The technique comprises installing the tubular hanger with a setting tool. The tubular hanger may comprise a locking ring that is driven outward into engagement with a profile in the wellhead. The setting tool is adapted to rotate a moveable member of the tubular hanger relative to the tubular hanger body so as to drive the moveable member to expand the locking ring outward to engage a profile in the wellhead. The moveable member may be wedged between the locking ring and the tubular hanger body. The setting tool may be adapted to enable the moveable member and the tubular hanger body to be rotated independently. The annulus between the tubular hanger and the wellhead may be sealed by a seal that has a plurality of sealing elements that are coupled together by a series of catches.Type: ApplicationFiled: April 29, 2009Publication date: November 4, 2010Applicant: Vetco Gray Inc.Inventor: Charles E.
