  • Patent number: 11274522
    Abstract: An apparatus and method for using a pressure-powered tool to perform a downhole operation in a well determine the operating condition of the tool based on indications of pressure in a region associated with the tool. If the pressure indications are indicative of an undesired operating condition, corrective action is taken, such as mechanically shifting the tool or rupturing the rupture disc of an electric rupture disc (ERD) system to shift the tool to a desired operating condition.
    Type: Grant
    Filed: December 9, 2019
    Date of Patent: March 15, 2022
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: Chao Wang, Julien Bost, Vincent Nicolas, Abbigail Ullrich, Quangen Du
  • Patent number: 11067106
    Abstract: A system and method for providing redundancy in hydraulic circuits in multi-cycle hydraulic tools is described. The problems of dysfunctional hydraulic tool due to the failure of electromechanical actuators are addressed by providing redundant actuators and associated circuitry design.
