Patent number: 8936112Abstract: A downhole tool may include a generally hollow piston having a trigger element extending therefrom, the piston configured to slide along an axial cavity extending through a tubular body of the tool. The trigger element may move from a first position where the trigger engages a support on the body and the piston is fixed, to a second position where the trigger disengages and the piston is released. The tool may also include a generally tubular relief sleeve releasably coupled with the piston using a shear pin, while the trigger element is in the first position, and disposed between the trigger and an extension of the piston, to allow the sleeve to slide between the trigger and the extension after shearing of the pin. The piston, sleeve and pin may be configured to allow the sleeve to release from the piston in response to the shearing of the pin.Type: GrantFiled: August 24, 2012Date of Patent: January 20, 2015Assignee: Halliburton Energy Services, Inc.Inventors: Erik Dithmar, Philippe R Fanuel, Stein Eric Moi, Luis Quintana

Patent number: 7975783Abstract: In accordance with an embodiment of the present invention, a drilling tool includes a tubular body defining a longitudinal axial cavity extending therethrough and defining at least one cutter element recess. The drilling tool also includes a cutter element at least partially disposed within the at least one cutter element recess and includes at least first and second cutting arms at least substantially disposed within the cutter element recess in a retracted position. The first and second cutting arms are operable to move from the retracted position to an extended position in which the first and second cutting arms extend at least partially beyond a periphery of the tubular body. The first and second cutting arms and the tubular body enclose a space when the first and second cutting arms are in the extended position.Type: GrantFiled: August 28, 2009Date of Patent: July 12, 2011Assignee: Halliburton Energy Services, Inc.Inventors: Philippe Fanuel, Jean-Pierre Lassoie, Olivier Mageren, Luis Quintana, Erik Stein Moi, Erik Dithmar

Publication number: 20100126715Abstract: The invention relates to a bottom tool comprising a tubular body (1) with an axial chamber, a hollow piston (8) capable of sliding in said axial chamber, and an actuation device including a trigger member (14) connected to the hollow piston and capable of displacement from a hollow-piston immobilisation position to a withdrawal position in which it releases the hollow piston, a detent tubular sleeve (16) of the trigger member connected to the hollow piston by at least one shearing pin (17), and means for temporarily blocking the detent tubular sleeve that generates a hydraulic pressure rise on the tubular sleeve with a shearing of said at least one shearing pin and the sliding of the detent tubular sleeve in a release position in which the trigger member is capable of displacement into its withdrawal position.Type: ApplicationFiled: January 11, 2007Publication date: May 27, 2010Inventors: Erik Dithmar, Philippe R.
