Patent number: 10138706Abstract: A technique includes running a seat assembly on a conveyance line into a tubing string, which has previously been installed in a well. The seat assembly includes a seat, which is adapted to receive an untethered object. The technique includes attaching the seat assembly to the string at a location downhole in the well; receiving the object to create a fluid barrier; and diverting fluid using the fluid barrier.Type: GrantFiled: May 13, 2015Date of Patent: November 27, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jason Baihly, Michael Bertoja, Robert A. Parrott, Bruno Lecerf, Don Aldridge

Patent number: 8944171Abstract: A technique includes deploying a string that includes a seat assembly in a well; and running a shifting tool in a passageway of the string. The shifting tool shifts the seat assembly to cause the seat assembly to transition between a first state in which the seat assembly forms a seat that is adapted to allow an untethered object communicated in the passageway of the string to pass through the seat assembly to a second state in which the seat assembly is adapted to catch the object to form a fluid barrier in the string. The fluid barrier is used to divert fluid in the tubing string to perform, for example, a stimulation operation.Type: GrantFiled: August 3, 2011Date of Patent: February 3, 2015Assignee: Schlumberger Technology CorporationInventors: Robert A. Parrott, Bruno Lecerf, Sergey Vladimirovich Solovyov, Mikhail Petrovich Gusev, Ilya Anatolievich Pavlov, Jason Baihly, Michael Bertoja

Patent number: 7762331Abstract: A process is disclosed for assembling a loading tube for a perforating gun for use in a perforating system. At a first location, e.g., a shop, which is not the location at which perforating operations will be conducted, the loading tube is completely assembled. The completely assembled loading tubing is then transported to a second location where perforating operations are to be conducted. In one embodiment, an RF-safe initiator, wiring, a detonating cord and a plurality of shaped charges are installed into the loading tube at a first location. The RF-safe initiators may comprise an exploding foil initiator or an exploding bridge wire. A process for assembling a loading tube for a single-shot perforating gun is also disclosed.Type: GrantFiled: December 21, 2006Date of Patent: July 27, 2010Assignee: Schlumberger Technology CorporationInventors: Kenneth Goodman, Michael Bertoja, Luis Ochoa

Patent number: 7510001Abstract: Various technologies described herein involve apparatuses for actuating a downhole tool. In one implementation, the apparatus may include a pressure sensor for receiving one or more pressure pulses and an electronics module in communication with the pressure sensor. The electronics module may be configured to determine whether the pressure pulses are indicative of a command to actuate the downhole tool. The apparatus may further include a motor in communication with the electronics module. The motor may be configured to provide a rotational motion. The apparatus may further include a coupling mechanism coupled to the motor. The coupling mechanism may be configured to translate the rotational motion to a linear motion. The apparatus may further include a valve system coupled to the coupling mechanism. The valve system may be configured to actuate the downhole tool when the valve system is in an open phase.Type: GrantFiled: February 24, 2006Date of Patent: March 31, 2009Assignee: Schlumberger Technology Corp.Inventors: Christian C. Spring, Matthe Contant, Kenneth Goodman, Samuel Tissot, Michael Bertoja

Publication number: 20070163774Abstract: A technique is provided to control flow in a well. A well completion comprises one or more flow control valve systems coupled by an electric line and a hydraulic line. Each flow control valve system comprises a flow control valve responsive to hydraulic input via the hydraulic line and an electro-mechanical device. The electro-mechanical device is responsive to inputs via the electric line and is used to control hydraulic input to the corresponding flow control valve.Type: ApplicationFiled: January 13, 2006Publication date: July 19, 2007Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Pierre Hosatte, Thomas MacDougall, Stephane Hiron, Michael Bertoja

Patent number: 7108065Abstract: A technique for preventing mineral, mineral salt and other deposits from impeding the motion of movable components in a submerged environment. The technique allows for a movable component in a submerged environment to move freely beneath a deformable member. As the member deforms, it fractures deposition products so they do not significantly impede the path of the movable component.Type: GrantFiled: December 19, 2002Date of Patent: September 19, 2006Assignee: Schlumberger Technology CorporationInventors: Michael Bertoja, Christophe Rayssiguier
