Patent number: 10480248Abstract: A valve for subterranean whipstock service has a side port and a through passage with a biased movable sleeve to shift between circulation mode into the annulus and flow through mode for setting an anchor and then feeding window mill nozzles. The valve is run in when in circulation mode to allow operation of a measurement while drilling device. When the whipstock is properly oriented the pressure is increased to break a shear pin to allow a spring to bias the sleeve to the flow through position. The shifting of the sleeve opens a bypass passage around the restriction orifice that was first used to build pressure to break the shear pins that let the sleeve move under spring bias. As a result the spring can hold the sleeve in position despite high flow rates needed to remove cuttings from the mill as the window is opened.Type: GrantFiled: March 8, 2018Date of Patent: November 19, 2019Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Dylan A. Bulloch, Gregory L. Hern, Larry T. Palmer, Jason L. Cullum

Patent number: 9169697Abstract: Downhole abrading tools have one or more identification tags disposed in or on the cutting end of the tools, and a housing having a detector and a relay module. The identification tags emit one or more signals that are detected by the detector which is disposed in close proximity to the cutting end. The relay module is operatively associated with the detector. During operation of the tool, the cutting end is worn causing release or destruction of one or more identification tags. The release or destruction of one or more identification tags causes a change in the signal or signals being detected by the detector. The signal change(s) is/are communicated through the relay module to the operator so that the operator can identify in real-time the amount of wear of the cutting end and, in some embodiments, the location of the wear of the cutting end.Type: GrantFiled: February 25, 2013Date of Patent: October 27, 2015Assignee: Baker Hughes IncorporatedInventor: Larry T.

Patent number: 8919452Abstract: A casing spear may comprise a mandrel, and a slip assembly comprising at least one slip. The at least one slip may comprise a generally wedge-shaped surface positioned and configured to cause the at least one slip to move radially outwards relative to the mandrel in response to a rotation of the mandrel and a torque acting on the slip assembly, the torque opposing the rotation of the mandrel. Additionally, a method of operating a casing spear may comprise inserting a casing spear into a casing, rotating a mandrel of the casing spear, applying a torque to a slip assembly of the casing spear with the casing, opposing the rotation of the mandrel, and applying a force in a radial direction to at least one slip of a slip assembly of the casing spear in response to the torque.Type: GrantFiled: October 24, 2011Date of Patent: December 30, 2014Assignee: Baker Hughes IncorporatedInventors: Larry T.

Patent number: 7661478Abstract: A downhole tool can perform a series of operations with balls of the same size where movement caused by pressuring up on the first ball positions the next seat to accept another ball just like it. In a preferred embodiment a circulation sub is run in with a port closed and a first seat comprising of collets pushed together and preferably lined with a sleeve are in position to accept a first ball to perform a downhole operation and thereafter pass the ball and open the port. The act of opening the port gives support, by reducing their dimension, to the next assembly of collets also preferably lined with a sleeve so that they are energized to accept the same size ball. Pressuring up on the second ball can shift another sleeve to close the circulation port. The tool is modular and more than one module can be deployed in a given bottom hole assembly.Type: GrantFiled: October 19, 2006Date of Patent: February 16, 2010Assignee: Baker Hughes IncorporatedInventors: Larry T.
