Patent number: 10415341Abstract: A downhole system including tubular casing string and a packer setting joint configured to receive a packer therein. The packer setting joint includes an interior and an exterior, and all interior and exterior surfaces from an uphole to a downhole end of the packer setting joint are machined surfaces. The uphole end of the packer setting joint is connected to the casing string, and the downhole end of the packer setting joint is connected to the casing string. The packer setting joint has a greater burst strength than a burst strength of a casing joint connected to the packer setting joint within the casing string.Type: GrantFiled: July 22, 2015Date of Patent: September 17, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Jack D. Farmer, David B. Ruddock, Michael J. Naquin, Allan R. McCoy

Publication number: 20170234091Abstract: A hydraulically operated downhole tool located at a depth where control line hydrostatic pressure would normally set the tool is temporarily isolated from hydrostatic pressure and changes thereto from well exposure or downhole operations until properly located. A removable barrier is placed in the control line to the tool at a height from the tool that limits the hydrostatic force exposed to the actuation mechanism for the tool. The preferred barrier is a rupture disc that is selectively broken with applied pressure from a remote location, typically the surface above the well. The mounting depth of the barrier can be varied to control the maximum hydrostatic pressure seen by the tool as it is advanced to the intended position.Type: ApplicationFiled: February 11, 2016Publication date: August 17, 2017Applicant: BAKER HUGHES INCORPORATEDInventors: Stephen H. Bisset, Gary L. Anderson, David B. Ruddock, Robert J. Taylor

Patent number: 9447649Abstract: A packer system including a packer and a setting mechanism. The setting mechanism has a setting piston that is actuatable in response to a fluid pressure in order to set the packer with the setting piston. The setting mechanism prevents actuation of the setting piston until the pressure is decreased below a threshold pressure from a value greater than the threshold pressure. A method of setting a packer is also included.Type: GrantFiled: June 6, 2013Date of Patent: September 20, 2016Assignee: BAKER HUGHES INCORPORATEDInventors: James C. Doane, Robert J. Taylor, Peter J. Fay, David B. Ruddock, Scott D. Collins, Rafael Ramirez, Gary L. Anderson

Patent number: 8365829Abstract: A pluggable seat includes, a first portion, positionable within a tubular, that is receptive to a runnable member seatable thereagainst, a second portion positioned downstream of the first portion, having a radial dimension smaller than a smallest radial dimension of the first portion, and a profile disposed at the second portion configured to increase resistance to extrusion of a runnable member past the pluggable seat in comparison to the same pluggable seat without the profile.Type: GrantFiled: September 11, 2009Date of Patent: February 5, 2013Assignee: Baker Hughes IncorporatedInventors: Justin Kellner, Travis Harris, Jason Coe, Dwayne Walkoviak, James Scott Sanchez, David B.

Patent number: 8157090Abstract: An organization system for a series of objects to be sequentially run downhole is disclosed. The preferred objects are spheres of progressively larger diameter put into a wellbore to land at discrete locations for operation of ports in a given sequence so that a specific producing zone or zones can be completed in increments that preferably go in an uphole direction as progressively larger spheres are inserted. In the preferred embodiment the process is fracturing where a series of ported subs are operated to selectively open for the fracture procedure at a specific location and then close or become isolated when another sphere is dropped. Optionally the balls can be recovered at the surface when production starts. The organizer prevents size confusion and gives a ready feedback as to the progress of a given job. Trays can be stacked and carried in a carrying case.Type: GrantFiled: October 23, 2009Date of Patent: April 17, 2012Assignee: Baker Hughes IncorporatedInventors: Donald F. Ingvardsen, Rafael Ramirez, David B. Ruddock, Michael J. Naquin

Patent number: 7673677Abstract: Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a reusable seat disposed within the bore. The seat comprises a slidable element, a fixed element, a plug element support member, a seat inner diameter, and a return member to urge the slidable element toward the run-in position. The plug element support member has a retracted position when the seat is in the run-in position and an extended position when the seat is in the set position. A plug element adapted to be disposed into the bore and landed on the seat to restrict fluid flow through the bore and the well conduit is used to move the plug element support member from the retracted position to the extended position, thereby providing support to the plug element landed on the seat.Type: GrantFiled: August 13, 2007Date of Patent: March 9, 2010Assignee: Baker Hughes IncorporatedInventors: James G. King, David B. Ruddock

Patent number: 7644772Abstract: Apparatuses for restricting fluid flow through a well conduit comprise a housing having a longitudinal bore and a seat disposed within the bore. The seat has a first position when the apparatus is in the run-in position and a second position when the apparatus is in the set position. The seat comprises an arcuate member comprising a plurality of slits defining a plurality of segment members having a gap there-between. Each of the gaps are variable such that movement of segment members inwardly causes the gaps to be narrowed or closed off completely when a plug element is disposed into the bore and landed on the arcuate member to move the arcuate member from the first position to the second position, causing restriction of fluid flow through the bore and the well conduit.Type: GrantFiled: December 22, 2008Date of Patent: January 12, 2010Assignee: Baker Hughes IncorporatedInventors: Marcus A.
