Publication number: 20230313673Abstract: A technique facilitates use of sensor data, e.g., pressure data, associated with hydraulic control lines. According to an embodiment, a well string is deployed in a borehole and comprises a tool coupled with a hydraulic control line and operated via hydraulic inputs delivered through the hydraulic control line. Additionally, a sensor is coupled to the hydraulic control line to monitor pressure in the hydraulic control line. The sensor may be located permanently downhole proximate the tool. A control module is configured to collect data from the sensor and to compare the data to a baseline pressure profile associated with the tool. The sensor data may be used to determine characteristics related to operation of the tool.Type: ApplicationFiled: June 2, 2023Publication date: October 5, 2023Inventors: Steven Nicholas Hill, Darcio Aparecido Braga, Geoffrey Pinard, Mannix Flores-Cruz

Patent number: 11174702Abstract: A downhole tool includes an upper flow tube connected to a lower flow tube, an upper flapper sub-assembly including an upper flapper, and a lower flapper sub-assembly including a lower flapper. The upper and lower flapper sub-assemblies are installed with respect to the upper and lower flow tubes in an “O” configuration such that the upper and lower flapper sub-assemblies are in a closed position. The upper and lower flapper sub-assemblies are capable of being independently actuated. The upper and lower flow tubes remain stationary when the upper flapper sub-assembly or the lower flapper sub-assembly is actuated from the closed position to an open position.Type: GrantFiled: August 15, 2018Date of Patent: November 16, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Marco Quilico, Jason Henry, Ignacio Marquez, Garis McCutcheon, Geoffrey Pinard

Patent number: 9103185Abstract: A technique facilitates prolonging the useful life of a subsurface valve without requiring replacement of the entire hydraulic chamber housing of the subsurface valve. A removable piston tube is provided and may be inserted into a valve housing of a subsurface valve. The removable piston tube is removably secured within a piston passage in the valve housing via a fastening mechanism. If necessary, the removable piston tube can be removed and replaced without requiring replacement of the overall housing.Type: GrantFiled: November 7, 2011Date of Patent: August 11, 2015Assignee: Schlumberger Technology CorporationInventors: David James Biddick, Paul G. Goughnour, Geoffrey Pinard

Publication number: 20110155396Abstract: An actuating component for a downhole tool is provided that includes a main actuating bore and an actuating liner configured to be accommodated within the main actuating bore. The actuating component may further include a piston configured to sealingly and translatably fit within the actuating liner and be coupled to the downhole tool wherein movement of the piston relative to the actuating liner actuates the downhole tool. A method of actuating a downhole tool is also provide that may include installing an actuating liner within a main actuating bore and providing a piston configured to translatably and sealably be accommodated within the actuating liner. The method may further comprise coupling the piston to an operative component of the downhole tool and applying pressure to a surface of the piston, thereby moving the piston relative to the actuating liner.Type: ApplicationFiled: December 29, 2009Publication date: June 30, 2011Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Geoffrey Pinard, David E.
