The technique may be useful in production applications, but the technique also can be used in fluid injection applications, e.g. gas injection applications. The technique employs a base pipe and a sand screen surrounding the base pipe. The base pipe comprises a plurality of flow restriction openings of reduced size and deployed in a selected pattern along the base pipe. The size and arrangement of the flow restriction openings reduces the peak flux of radial fluid flow through the sand screen to a rate less than a sand screen erosion rate.Type: ApplicationFiled: October 8, 2012Publication date: April 18, 2013Inventors: Robin Greene, Terje Moen

Patent number: 8403065Abstract: A riser for use in boring a subsea wellbore having a gooseneck assembly connected onto the riser. The gooseneck assembly has an outlet that couples with a flowline on the riser and a connector assembly that selectively decouples the gooseneck assembly from the flowline. A release member, such as a wire, cable, or rod, is attached to the connector so the connector assembly can be actuated by manipulating the release member from a remote location.Type: GrantFiled: September 4, 2009Date of Patent: March 26, 2013Assignee: Detail Designs, Inc.Inventors: Robert H. Taylor, Arthur Jones

Patent number: 8403057Abstract: A wellhead connection including first and second housings with the first housing partly within the second housing to form an annulus. The housings form a seal to a cylindrical inner bore when connected together. The first housing has a circumferential groove formed in its outer periphery. A radially expandable and contractable latch ring formed from latch ring segments is located in the annulus adjacent the circumferential groove. Radial actuators extend through the second housing to the latch ring segments to move the latch ring segments between a contracted position with the latch ring in contact with the circumferential groove, and an expanded position, with the latch ring out of contact with the circumferential groove. The upper and lower housings are adapted to lock the latch ring in the contracted position by applying a downward force on the latch rings, or by tightening the bottom connector to a wellhead member.Type: GrantFiled: August 17, 2010Date of Patent: March 26, 2013Assignee: Stream-Flo Industries Ltd.Inventors: Doyle W. Rodgers, Keith David Farquharson

Patent number: 8403066Abstract: A hybrid junction assembly is provided. The hybrid junction assembly may comprise a junction body configured to sealingly couple to a first control line and a second control line. In addition, the assembly may include a transfer conduit configured to fit within a hybrid control line such that an annulus is formed between the transfer conduit and the hybrid control line. The first control line and the transfer conduit may form a first communication pathway and the second control line and the annulus may form a second communication pathway. The transfer conduit and the hybrid control line may be sealingly coupled to the junction body.Type: GrantFiled: February 9, 2010Date of Patent: March 26, 2013Assignee: Schlumberger Technology CorporationInventors: Ramaswamy Meyyappan, Yasser El-Khazindar, Thomas D.

Publication number: 20130062073Abstract: An apparatus including a downhole tool for conveyance in a wellbore extending into a subterranean formation. The downhole tool includes a mandrel, and a first packer and a second packer expandable from the mandrel into contact with a wall of the wellbore. The downhole tool includes a standoff coupled to the mandrel between the first packer and the second packer and having a rigid outer perimeter that is diametrically larger than an outer perimeter of the mandrel.Type: ApplicationFiled: November 28, 2011Publication date: March 14, 2013Inventor: Nathan Landsiedel

Patent number: 8393397Abstract: An apparatus for separating a tubular string from a subsea well installation. The apparatus includes a heave compensator tensioning the tubular string, a subsea actuator assembly positioned within the tubular string, a subsea controller in communication with the subsea actuator assembly, a subsea safety tree positioned within the subsea well installation and a fluid delivery subsystem. An output signal generated by the subsea controller responsive to receipt of a predetermined input signal releases a piston of the subsea actuator assembly such that the tension in the tubular string shifts the piston relative to a cylinder energizing fluid in the fluid delivery subsystem to actuate the retainer valve, the shut-in valve assembly, the vent sleeve and the latch assembly, thereby safely separating the tubular string from a subsea well installation.Type: GrantFiled: March 17, 2010Date of Patent: March 12, 2013Assignee: Halliburton Energy Services, Inc.Inventors: Ross John Trewhella, Darryl K.

Publication number: 20130056222Abstract: Concentric control lines have an outer line disposed about one or more inner lines. Encapsulated together, the lines only require one penetration through the wellhead to extend downhole. At the wellhead, the lines communicate with an operating system, which can provide hydraulics, electric power, signals, or the like for downhole components. Beyond the wellhead, the concentric lines extend along the tubing to a manifold. The outer line sealably terminates at the manifold's inlet, while the inner conduit passes out an outlet with a sealed fitting to connect to a downhole component. A downhole line couples to an outlet of the manifold and communicates internally with the outer conduit terminated at the manifold's inlet. This downhole line can then extend to the same downhole component or some different component.Type: ApplicationFiled: September 7, 2011Publication date: March 7, 2013Applicant: WEATHERFORD/LAMB, INC.Inventors: Roddie R.
