Patent number: 10487602Abstract: A well tool apparatus comprises a control arrangement configured to control response of the downhole tool by varying a bore-annulus pressure difference. The control arrangement includes a valve piston longitudinally slidable in a generally tubular controller housing that is in operation substantially co-axial with the wellbore, to open or close a valve port to a fluid flow connection between the drill strings interior and the tool. A latch mechanism is configured to latch the valve piston against movement in one axial direction, keeping the valve piston in an open or a closed condition. Unlatching of the valve piston requires displacement thereof in the other axial direction to a mode change position. A stay member is automatically displaceable under hydraulic actuation responsive to bore-annulus pressure differences above a trigger threshold value, to obstruct movement of the latched valve piston under hydraulic actuation to the mode change position.Type: GrantFiled: March 24, 2015Date of Patent: November 26, 2019Assignee: Halliburton Energy Services, Inc.Inventors: John Gerard Evans, Bradley David Dunbar, William Browning Bradford, David Wayne Cawthon, Jean-Pierre Lassoie

Patent number: 10443349Abstract: A well tool apparatus comprises a control arrangement configured to control response of the downhole tool by varying downhole drilling fluid conditions. The control arrangement includes a valve piston longitudinally slidable in a generally tubular controller housing that is in operation substantially co-axial with the wellbore, to open or close a valve port to a fluid flow connection between the drill strings interior and the tool. A latch mechanism is configured to latch the valve piston in an activated mode and/or a deactivated mode. Unlatching of the valve piston can be effected by displacement thereof in a particular axial direction to a mode change position. A stay member is automatically displaceable in the particular actual direction under hydraulic actuation responsive to above-threshold drilling fluid conditions, to obstruct movement of the valve piston under hydraulic actuation to the mode change position.Type: GrantFiled: April 15, 2015Date of Patent: October 15, 2019Assignee: Halliburton Energy Services, Inc.Inventors: Benjamin Evans, Olivier Christophe Roche, Jean-Pierre Lassoie

Patent number: 8807246Abstract: Described herein is a reamer tool (100) having a body (105) with bays (115) in which cutter arms (110) are mounted for deployment between a stowed position and a deployed position. A deployment mechanism is provided for deploying the cutter arms from their stowed position to their deployed position that maintains each cutter arm in a position that is substantially parallel to a longitudinal axis of the body (105) whilst in its stowed position and in its deployed position as well as during its deployment from its stowed position to its deployed position. A control module (300) is also described for controlling the deployment of the cutter arms (110). The control module (300) comprises a motor (310), a gearing mechanism (315) and a moveable element (320) that closes a port (385) in a first position and opens the port (385) in a second position.Type: GrantFiled: October 22, 2012Date of Patent: August 19, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Jean-Pierre Lassoie, John Ransford Hardin, Jr.
