Patent number: 9435159Abstract: A polycrystalline diamond compact comprising a diamond table is formed in a high-pressure, high-temperature process using a catalyst, the catalyst being substantially removed from the entirety of the diamond table, and the diamond table attached to a supporting substrate in a subsequent high-pressure, high-temperature process using a binder material differing at least in part from a material of the catalyst. The binder material is permitted to penetrate substantially completely throughout the diamond table from an interface with the substrate to and including a cutting surface, and the binder material is selectively removed from a region or regions of the diamond table by a conventional technique (e.g., acid leaching). Cutting elements so formed and drill bits equipped with such cutting elements are also disclosed.Type: GrantFiled: October 28, 2013Date of Patent: September 6, 2016Assignee: Baker Hughes IncorporatedInventor: Danny E.

Patent number: 9416636Abstract: A hydraulic cutting tool, a system, and a method are for hydraulic cutting through a pipe wall of a pipe body. For this purpose, the cutting tool is provided with at least one cutting section comprising at least one fluid discharge body. Each such fluid discharge body comprises at least two outwardly directed discharge openings having non-parallel discharge directions directed at a common intersection point located outside the fluid discharge body. The cutting is carried out by means of an abrasive fluid being supplied, via a flow-through pipe string, to the at least one fluid discharge body from a remote location. Thereby, abrasive cutting jets will discharge at high velocity from the fluid discharge body so as to meet and disperse in the intersection point, thus weakening the further cutting ability of the cutting jets.Type: GrantFiled: April 7, 2014Date of Patent: August 16, 2016Assignee: Well Technology ASInventors: Morten Myhre, Arne Gunnar Larsen, Roy Inge Jensen, Patrick Andersen, Erlend Engelsgjerd, Markus Iuell, Arnt Olav Dahl, Nils Rune Haga, Arnold Ostvold

Patent number: 9416612Abstract: The cutting structure on the lower mill is arrayed in rows that are preferably parallel. The cutting structure in each row is made sharper and more durable than prior designs with the objective of cutting the window higher than where the window mill started the window. The use of the rows increases the contact stress of the inserts on the casing inside wall because at any given time fewer and sharper inserts are cutting the casing wall to lengthen the window. As a row wears down the next row takes over to continue the cutting where the previous row was active and to further penetrate the casing wall. The cutout angle can also increase as this occurs. As a result a decreased insert density results in more effective casing wall cutting to extend the window to allow larger tools to exit into the window off the whipstock.Type: GrantFiled: December 4, 2013Date of Patent: August 16, 2016Assignee: Baker Hughes IncorporatedInventors: Calvin J. Stowe, Tejas J. Ghegadmal, Andrew D. Ponder

Patent number: 9416623Abstract: A tool string having a pressure dependent mandrel and actuator assembly can operate at the annulus pressure within a wellbore to lock the mandrel actuator assembly and prevent further motion of the mandrel within the tool string as the tool string is moved upward or downward in the wellbore. The tool string can further include a valve connected to the actuator assembly, where the valve can be in an open configuration within the wellbore due to the annulus pressure and related motion of the mandrel, and then be locked in an open configuration regardless of the annulus pressure as the tool string is moved upward or downward in the wellbore.Type: GrantFiled: December 18, 2013Date of Patent: August 16, 2016Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Kevin Michael Renkes, Scott Luke Miller
