    摘要: A method of assembling an optical fiber cable on production casing includes positioning the optical fiber cable against a production casing at a hole of a well site, and affixing the optical fiber cable against the production casing by applying an adhesive to the production casing to secure the optical fiber cable against the production casing. The method further includes applying pressure to the adhesive to adhesively bond the optical fiber cable to the production casing along a length of the production casing while the production casing is being run-in-hole.

    摘要: A downhole sensor deployment assembly includes a body attachable to a completion string and one or more arms pivotably coupled to the body. A sensor pad is coupled to each arm and movable from a retracted position, where the sensor pad is stowed adjacent the completion string, and an actuated position, where the sensor pad is extended radially away from the completion string. One or more actuators are pivotably coupled to the body at a first end and pivotably coupled to a corresponding one of the one or more arms at a second end, the one or more actuators being operable to move the sensor pad to the actuated position. One or more sensor devices are coupled to the sensor pad for determining a resistivity of a formation, the one or more sensor devices comprising at least one of a sensing electrode, a transceiver, and a transmitter.

    摘要: An assembly for use in a well, where the assembly includes a casing section, a modular carrier body, at least one securing ring, and at least one at least one port through the modular carrier body for connecting a compression fitting for at least one fiber optic line. The modular carrier body has a shape that can conform to the outer diameter of the casing section, and has a carrier body interior to house at least one fiber optic line, and a fiber optic line splicing assembly. At least one securing ring has a shape conformable to both the outer diameter of the casing section and a portion of a surface of the modular carrier body. The assembly can have two securing rings on either end of the modular carrier body as it is mounted to the casing.

    摘要: A method of perforating a wellbore is provided. The method includes generating a shockwave that propagates throughout said wellbore by firing a perforation device at a perforating direction, and measuring the shockwave at a fiber optic cable in the wellbore using the fiber optic cable. The method further includes determining an orientation of the fiber optic cable relative to the perforating direction based on the shockwave and the perforating direction, and changing the perforating direction based on the orientation of said the optic cable for a subsequent perforation of the wellbore to minimize damage to the fiber optic cable during the subsequent perforation. The fiber optic cable is an existing cable that has been deployed before the method starts.
