  • Stand break detection systems and methods
    Patent number: 11530608
    Abstract: Aspects of the present disclosure relate to a stand break detection system. In some embodiments, the stand break detection system includes a sensor and a data processing system. The sensor may measure a movement of drill pipe as it is tripped out of a wellbore. The processor may execute instructions stored in a memory to receive measured movement data from the sensor and identify a stand break associated with one or more drill pipes using the measured movement data.
    Type: Grant
    Filed: February 19, 2020
    Date of Patent: December 20, 2022
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION
    Inventors: James Minh Tran, Richard Woods, Tania Maria Oviedo Gutierrez, Irina Kim
