Patent number: 9695678Abstract: A system and method allows the operation of a remotely located tool in an application where there is a telescoping space out joint in such a manner that the hanger need not be released. A hydraulic piston is surface actuated to move gripping teeth against the pipe and then take the pipe with the gripping teeth so that a tool that is engaged by the string can be remotely operated while safety features for the well can remain operative.

Rather, a check valve holds the shifted piston position until a differential pressure on the check valve drops to a predetermined value so that the check valve acts as a dump valve. The system operates off annulus pressure if the control line is damaged.Type: GrantFiled: June 6, 2014Date of Patent: July 4, 2017Assignee: Baker Hughes IncorporatedInventors: Andrew Webber, Drayton W.

Patent number: 8931548Abstract: A modular tool for use in subterranean formations includes a first module, a second module and one or more connectors for connecting the first and second modules. In particular, the first module includes a first collar that at least partially defines an exterior of the tool and that includes a first engagement mechanism at a first end of the collar and a second engagement mechanism at a second end of the collar. The first module also includes a fluid passageway for passing drilling fluid therethrough. The second module has a similar configuration as includes similar architecture. The one or more connectors facilitate the connection of at least one flowline fluidly connected to an exterior of the tool, and an electrical pathway for transmitting power and/or data between the modules.Type: GrantFiled: February 8, 2011Date of Patent: January 13, 2015Assignee: Schlumberger Technology CorporationInventors: Ashers Partouche, Steven G. Villareal, Julian J. Pop, Albert Hoefel, Kent D. Harms

Patent number: 8919457Abstract: An apparatus for determining the weight on a drill bit and axial forces along a drill string drilling though an earthen formation. The apparatus comprising an LVDT incorporated into a torsional bearing of a magneto-rheological damping system such that the LVDT senses the relative displacement and accelerations between a bearing mandrel portion and a bearing casing portion of the torsional damper. The LVDT is calibrated with respect to a spring in the damping system that resists relative motion between the bearing mandrel and bearing casing such that the output of the LVDT can be transformed into the force associated with the weight on the drill bit, and the same LVDT accelerations combined with the mass distribution along the drill string to determine axial stresses.Type: GrantFiled: April 29, 2011Date of Patent: December 30, 2014Inventor: Mark Hutchinson

Publication number: 20140326513Abstract: An impact dissipation tool for supporting a downhole tool in downhole applications. The tool includes a base and a housing. The tool also includes a carriage located within the housing and coupled to the base, the carriage being movable relative to the housing upon a predetermined impact force. A dissipator disposed inside the housing is collapsible due to the relative movement of the carriage and the housing. The collapse of the dissipator dissipates the impact force transferred to the downhole tool.Type: ApplicationFiled: July 17, 2014Publication date: November 6, 2014Applicant: Schlumberger Technology CorporationInventors: Alan J. Sallwasser, Bulent Finci, Jaime Pedraza, Akio Kita

Patent number: 8820007Abstract: A post sleeve installation assembly includes: an elastomeric sleeve core shaped to form a post sleeve when positioned in uncured concrete, a removable stiffener inside the core, an aperture extending lengthwise in the stiffener, a locking element positioned within the core, and an assembly plate coupled to the stiffener. The assembly plate clamps to a prefabricated sleeve element, with the core and stiffener positioned within a post cavity of the sleeve element. an installation stake is positioned in the aperture and prevented from sliding upwards by the locking element. A release point on the assembly plate permits an operator to release the locking element for removal of the stake. To install a post sleeve, the operator positions the installation assembly, clamped to a prefabricated sleeve element, in a post hole with the stake resting on the bottom, then fills the hole with concrete, manipulating the stake to position the assembly.Type: GrantFiled: September 23, 2011Date of Patent: September 2, 2014Inventor: N. Eric Knudsen

Patent number: 8714284Abstract: An apparatus and method for producing pressure signals which indicate when weight-on-bit, during the drilling of a wellbore, exceed a predetermined, upper limit. The apparatus includes a first mandrel and a second mandrel that inserts into and is axially moveable within the first mandrel. The position of the second mandrel may be dependent upon the balance of a biasing member's biasing strength and the weight-on-bit exerted on the drill bit. If weight-on-bit values overcome the biasing strength of the biasing member, the second mandrel may move uphole within the first mandrel and create a pressure signal that is detectable at surface so that the operator is made aware that weight-on-bit values exceed the upper limit.Type: GrantFiled: September 16, 2010Date of Patent: May 6, 2014Assignee: BBJ Tools Inc.Inventor: Bradley R. Cote

Patent number: 8708066Abstract: A drilling apparatus including a drill collar forming part of a primary drilling assembly and having an outward opening groove in the side thereof, and a secondary drilling assembly. The secondary drilling assembly includes a tubular drill string connected at one end to the drill collar, a drilling motor mounted in the drill string, and a drill bit mounted at the other end of the drill string and connected to the drilling motor. The secondary drilling assembly is mounted in the drill collar so as to be movable between a first position in which the drill bit is seated in the groove, and a second position in which the bit projects laterally from the groove in the side of the drill collar.Type: GrantFiled: August 30, 2007Date of Patent: April 29, 2014Assignee: Schlumberger Technology CorporationInventors: Jacques Orban, Sami Iskander

Patent number: 8439129Abstract: An anti-stall tool in an oil well drilling assembly that controls reciprocation of the drill bit by a controller that alters weight-on-bit (WOB) depending upon measured downhole pressure or torque at the downhole motor. The controller receives preset high and low working pressure limits for the downhole motor and keeps the drill bit rotating by maintaining WOB during normal drilling operations, increasing WOB if sensed working pressure indicates that drill bit loading or torque is undesirably low, and reversing WOB by retracting the drill bit if excessive working pressure or torque is sensed.Type: GrantFiled: February 22, 2012Date of Patent: May 14, 2013Assignee: WWT International, Inc.Inventors: Philip Wayne Mock, Rudolph Ernst Krueger, IV

Patent number: 8381842Abstract: In various embodiments, a mining device can include a first housing portion and a second housing portion where relative movement between the first and second housing portions can extend and/or retract a cutting member with respect to the mining device. The mining device can further include a cable which can be mounted to the second housing portion where the cutting member is mounted to the cable and can be radially extended with respect to the first and second housing portions when the second housing portion is moved relative to the first housing portion along an axis. As the cutting member is extended, it can contact the sidewalls of a subterranean shaft to loosen material therefrom.Type: GrantFiled: July 25, 2011Date of Patent: February 26, 2013Inventors: Larry P.
