  • Magneto-optical sensor
    Patent number: 9133704
    Abstract: A magneto-optic sensor for oilfield application, the sensor (1, 1?, 101, 101?) receives an incident beam IB, IBA, IBB, IBC, IBD and comprises a polarizing element (3, 103) for providing a determined state of polarization beam and a Faraday rotator (4, 104) for providing a response beam having a modified state of polarization. The sensor provides a response beam (RB, RBA, RBB, RBC, RBD having an intensity dependent on an external magnetic field representative of a particular characteristic of a well-bore casing CC, CR applied on the Faraday rotator (4, 104).
    Type: Grant
    Filed: December 13, 2005
    Date of Patent: September 15, 2015
    Assignee: Schlumberger Technology Corporation
    Inventors: Frederique Kalb, Christine Aussibal
  • Apparatus for measuring an internal dimension of a well bore
    Patent number: 7884951
    Abstract: An apparatus for measuring an internal dimension of a well-bore comprising a tool adapted to be positioned inside the well bore. The tool comprises an optical caliper comprising an optical sensor providing a response correlated to the internal dimension of the well bore, the optical sensor being coupled to an optical fiber.
    Type: Grant
