Publication number: 20120292034Abstract: A side pocket mandrel has openings to receive a plurality of valves such that the flow of fluid from outside the string and into the tubular such as in gas lift will flow through the valves in series. The side pocket mandrel that has a single valve pocket can also be used in tandem with another similar side pocket mandrel to get the same dual barrier configuration to meet requirements of many jurisdictions of such a valve arrangement for tubular wall openings.Type: ApplicationFiled: May 19, 2011Publication date: November 22, 2012Applicant: BAKER HUGHES INCORPORATEDInventor: Peter J.

Patent number: 8291980Abstract: A tubular valving system includes a tubular having a plurality of ports. A plurality of sleeves are disposed at the tubular covering the plurality of ports, and a plug runnable within the tubular is seatingly engagable with the plurality of sleeves such that attainment of a first pressure applied against the plug and one of the plurality of sleeves causes movement of the one of the plurality of sleeves to thereby uncover at least one of the plurality of ports covered by the one of the plurality of sleeves. At least one of the plurality of sleeves is yieldable to allow passage of the plug upon attainment of a second pressure applied thereagainst, and a plurality of occlusive members occlude the plurality of uncovered ports until a later time.Type: GrantFiled: August 13, 2009Date of Patent: October 23, 2012Assignee: Baker Hughes IncorporatedInventor: Peter J.

Patent number: 8291982Abstract: A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular.Type: GrantFiled: December 29, 2011Date of Patent: October 23, 2012Assignee: Baker Hughes IncorporatedInventors: Douglas J. Murray, Robert S. O'Brien, Peter J. Fay, Sean L. Gaudette

Publication number: 20120227980Abstract: Plug element systems comprise a tubular member having at least two seats. An eccentrically-shaped plug member comprises an upper end portion and a lower end portion. The upper end portion comprises an upper end diameter can be less than, greater than, or equal to a lower end portion diameter of the lower end portion. The eccentric shape of the plug member permits it to pass through a first seat and land on a second seat comprising a second seat length where both the first seat and the second seat comprise substantially equal inner seat diameters.Type: ApplicationFiled: March 10, 2011Publication date: September 13, 2012Inventor: Peter J.

Publication number: 20120186806Abstract: A plurality of rows of locking dogs are provided with housing flexibility between rows to allow them to share a shear loading while leaving enough structural integrity in the housing to define the windows through which the dogs emerge. The dogs can also have extensions with a surface that grippingly engages the housing adjacent the window on extension of the dogs such that loads can transfer from the housing into the extension and into the profile in which the dog is disposed rather than passing the shear stress through the window edge into the dog that is in the profile. The dog configuration can also share the load on multiple contact surfaces of the housing to reduce stress at each contact location.Type: ApplicationFiled: January 25, 2011Publication date: July 26, 2012Applicant: BAKER HUGHES INCORPORATEDInventors: Peter J. Fay, Marcus A. Avant

Publication number: 20120080188Abstract: A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves one series of which can be put in the wide open position after run in for gravel packing and fracturing zones one at a time or in any desired order. These valves are then closed and another series of valves can be opened wide but with a screen material juxtaposed in the flow passage to selectively produce from one or more fractured zones. An annular path behind the gravel is provided by an offset screen to promote flow to the screened production port. The path can be a closed annulus that comes short of the production port or goes over it. For short runs an exterior screen or shroud is eliminated for a sliding sleeve with multiple screened ports that can be opened in tandem.Type: ApplicationFiled: December 13, 2011Publication date: April 5, 2012Applicant: BAKER HUGHES INCORPORATEDInventors: Bennett M.

Patent number: 8002044Abstract: A liner hanger has a housing with a pocket disposed on an inner wall surface and a slip slidingly engaged within the pocket. A moveable cover is disposed interior to the slip thereby restricting movement of the slip from a unset position to a set position. The liner hanger housing is secured in the string of casing and an actuator is mounted on the liner. As the liner is moved through the casing coupler, the actuator actuates the cover, causing the cover to be moved so that the slip can move axially downward from its unset position to its set position. As the cover is moved, the slip moves radially inward and grips the liner to secure the liner within the casing string of the wellbore.Type: GrantFiled: June 3, 2009Date of Patent: August 23, 2011Assignee: Baker Hughes IncorporatedInventors: Peter J.
