Patent number: 11475649Abstract: A method including obtaining a first image of a geographical location and a physical object located therein. Pixels in the first image are assigned to corresponding points in a Cartesian coordinate system defined specifically for the first image. The resulting virtual map includes a virtual representation of the physical object, a set of Cartesian coordinates assigned to a set of pixels in the pixels, and a set of Cartesian rotation angles assigned to the set of pixels. A first transform is calculated that scales the Cartesian coordinate system to a physical scale of the geographical location. A data structure stored in a data repository is formed by applying the first transform to the virtual map. The data structure includes the set of pixels, a set of scaled Cartesian coordinates, the set of Cartesian rotation angles, and a physical scale virtual representation of the physical object.Type: GrantFiled: November 6, 2019Date of Patent: October 18, 2022Assignee: Schlumberger Technology CorporationInventors: Andrey Konchenko, Kim Swift, Bruce MacKay, Sergey Doronichev, Siau Ban Teh, Markus Schlafli, Salvador Ruiz-Esparza, Jared Krichko, Ewan Maxwell, Rod Shampine, Apoorva Dubey, Jared Bruns

Patent number: 11359622Abstract: A system for generating variable frequency tube waves includes a high pressure multiplex pump having a number of plungers, with each plunger operatively coupled to a suction valve on a suction side and a discharge valve on a discharge side. The suction valve or the discharge valve of a first one of the plungers includes an opening, such that the modified plunger on a discharge stroke pushes fluid through the opening in the suction or discharge valve. The system includes a tubular fluidly coupling the high pressure multiplex pump to a wellbore, and a pressure sensor that receives tube waves generated by the high pressure multiplex pump and reflected from the wellbore.Type: GrantFiled: January 3, 2020Date of Patent: June 14, 2022Assignee: Schlumberger Technology CorporationInventors: Rod Shampine, Rajesh Luharuka, Edward Leugemors, Laurent Coquilleau, John Daniels

Patent number: 10697252Abstract: A valve assembly for reversibly governing fluid flow through coiled tubing equipment. Valves of the assembly may be directed by a telemetric line running from an oilfield surface. In this manner, valve adjustment and/or reversibility need not require removal of the assembly from the well in order to attain manual accessibility. Similarly, operation of the valves is not reliant on any particular flow rate or other application limiting means. As such, multiple fluid treatments at a variety of different downhole locations may take place with a reduced number of trips into the well and without compromise to flow rate parameters of the treatments.Type: GrantFiled: September 17, 2018Date of Patent: June 30, 2020Assignee: Schlumberger Technology CorporationInventors: Rex Burgos, Victor M.

Patent number: 10047592Abstract: A technique facilitates performance of a perforating operation in a wellbore. The technique comprises positioning a perforating gun assembly downhole in a wellbore via coiled tubing. The perforating gun assembly has a plurality of individually controllable perforating gun sections which may be selectively fired at different well zones. An optical fiber is deployed along the coiled tubing to deliver control signals to the perforating gun assembly. The control signals enable sequential firing of the individually controllable perforating gun sections at the desired locations, e.g. well zones, along the wellbore.Type: GrantFiled: May 15, 2013Date of Patent: August 14, 2018Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Rex Burgos, Douglas Pipchuk, Rod Shampine, Victor M.
