Patent number: 10781663Abstract: A tubular includes an outer surface, an inner surface defining a passage, and a plurality of openings extending through the outer surface and the inner surface. A sleeve is positioned within the passage. The sleeve includes an outer surface portion having at least one recess. At least one release member extends from the inner surface into the at least one recess. The at least one release member maintains the sleeve in a first configuration relative to the plurality of openings. At least one of the inner surface and the outer surface portion includes a self-holding connection that establishes one of a reduced diameter portion of the passage and an increased diameter portion of the sleeve. The self-holding connection is configured to maintain the sleeve in a second configuration axially shifted relative to the first configuration.Type: GrantFiled: July 13, 2018Date of Patent: September 22, 2020Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Carlos De La Cruz, Sean Gaudette, Robert O'Brien

Patent number: 10655431Abstract: A bypass diverter sub including a housing defining a flow passage, a control line bypass piston arranged within a control line bypass bore defined in a wall of the housing, and a balance line bypass piston arranged within a balance line bypass bore defined in the wall. An outer magnet is disposed within a magnet chamber and is operatively coupled to the control and balance line bypass. A flow tube profile is positioned within the flow passage and provides an inner magnet magnetically coupled to the outer. The flow tube profile is movable between a first position, where control line and balance line pressures circulate through the bypass diverter sub to a subsurface safety valve, and a second position, where the control line pressure is diverted into the flow passage and the balance line pressure is diverted into a balance line jumper conduit.Type: GrantFiled: March 11, 2016Date of Patent: May 19, 2020Assignee: Halliburton Energy Services, Inc.Inventors: Merced Gonzalez, Andrew Kelbie

Patent number: 10605047Abstract: An actuator assembly for effective interventionless activation of a valve in wells of multilateral architecture. The assembly may be pressure actuated from an oilfield surface even in certain circumstances where another valve in another leg of the well has been opened in a manner compromising pressure control of the well. Due to the multi-stage nature of the actuator, pressure based activation remains viable as a result of supplemental and/or fail-safe modes of actuation, for example, where such pressure control becomes compromised.Type: GrantFiled: October 26, 2016Date of Patent: March 31, 2020Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Dinesh Patel

Patent number: 10370938Abstract: A technique provides a simplified and cost-effective approach for deployment and operation of completion systems. The construction of the overall completion system and the deployment methodology provide an efficient approach for placement and operation of completion systems in a variety of wellbores. In many applications, the system and methodology may be used for sand control applications in which the completion equipment comprises sand control features, such as sand screens deployed along well zones.Type: GrantFiled: September 18, 2014Date of Patent: August 6, 2019Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventor: Dinesh Patel

Patent number: 10364986Abstract: A system and method for vent gas combustion in storage tank for heavy oil production is provided. Auxiliary burners located are provided for combusting the well casing gas. A burner management system for controlling the auxiliary burners is provided which receives a gas pressure value and initiates the auxiliary burners based upon one or more threshold values when the gas pressure exceeds the one or more pressure values. An auxiliary exhaust stack may be collocated with a main exhaust stack of a tank heater for the storage tank.Type: GrantFiled: October 15, 2015Date of Patent: July 30, 2019Assignee: REM Technology Inc.Inventors: Howard L. Malm, Leslie Allan Keast, Greg Brown

Patent number: 10337285Abstract: A downhole tool and method, of which the downhole tool includes a first sub defining a port extending radially therethrough, a second sub spaced apart from the first sub, and a housing connected with the first and second subs. A valve element is disposed at least partially within the housing, and is movable from a closed position to an open position. In the closed position, the valve element blocks fluid communication between a bore and an opening in the housing. When the valve element is in the open position, fluid communication between the bore and the opening is permitted. An actuation chamber is defined between the first sub, the housing, and the valve element, and is in fluid communication with the bore via a flow path that includes the port. A flow restrictor in the flow path is configured to slow fluid flow from the bore to the actuation chamber.Type: GrantFiled: December 16, 2016Date of Patent: July 2, 2019Assignee: INNOVEX DOWNHOLE SOLUTIONS, INC.Inventor: Justin Kellner
