Publication number: 20130299193Abstract: An apparatus and method can be used to positively retain a lockdown ring to axially secure a wellbore member in a wellhead housing. In embodiments, the wellbore member, such as a tubing hanger, can be secured by a lockdown ring having a cylindrical surface below a tapered surface. An energizing ring having a cylindrical surface above a tapered surface can be used to move the lockdown ring from an unset position to a set position, thus energizing the lockdown ring. After being energized, the two cylindrical surfaces can engage each other so that axial movement of the energizing ring, of up to a predetermined distance, does not cause the lockdown ring to move from a set position to an unset position.Type: ApplicationFiled: May 10, 2012Publication date: November 14, 2013Applicant: Vetco Gray Inc.Inventor: Khanh Anh Duong

Publication number: 20130299194Abstract: A shaped charge pipe cutter is constructed with the cutter explosive material packed intimately around an axially elongated void space that is continued through a heavy wall boss portion of the upper thrust disc. The boss wall is continued to within a critical initiation distance of a half-cuter junction plane. An explosive detonator is positioned along the void space axis proximate of the outer plane of the upper thrust disc. Geometric configurations of the charge thrust disc and end-plate concentrate the detonation energy at the critical initiation zone.Type: ApplicationFiled: May 10, 2012Publication date: November 14, 2013Inventors: William T.

Publication number: 20130299196Abstract: A self-actuated cyclical flow interruption valve on a deployment tool is positioned at a proximal end of a well completion assembly. Fluid is pumped though the self-actuated cyclical flow interruption valve and vented immediately distal of the valve, to return to surface of the well. A water hammer pulse is generated each time the self-actuated cyclical flow interruption valve closes, thereby generating an impact force that acts to push the completion equipment distally into the well. The continuous cyclic force of the impact facilitates placement of the completion equipment where desired in the well, including within a horizontal extension of the well. Fluid discharged through the self-actuated cyclical flow interruption valve circulates up to the surface through a vertical and inclined section of the well.Type: ApplicationFiled: July 16, 2013Publication date: November 14, 2013Inventor: Jack J.

Publication number: 20130299198Abstract: A downhole fluid flow control system for autonomously controlling the inflow of production fluids. The fluid flow control system includes a flow control assembly having a fluid flow path through which a fluid flows. A support structure is positioned in the fluid flow path. A plug is releasably coupled to the support structure such that when fluid flow through the fluid flow path induces sufficient movement in the support structure, the movement causes release of the plug from the support structure into the fluid flow path, thereby restricting subsequent fluid flow in at least one direction through the fluid flow path.Type: ApplicationFiled: February 25, 2013Publication date: November 14, 2013Applicant: Halliburton Energy Services, Inc.Inventors: John Charles Gano, Michael Linley Fripp
