  • Patent number: 9376906
    Abstract: A method and apparatus for evaluating the subterranean formation of a wellbore includes conveying a downhole tool in a wellbore via a cable, and determining the torque in the cable in real-time. The method further involves conveying the downhole tool on a wireline, and automatically triggering an alert when the torque reaches a certain level. The apparatus includes a cable, a downhole tool attached to the cable for conveyance within the wellbore, and a sensor to measure torque in the cable. The apparatus may also include a telemetry system to communicate the torque data to the surface. The downhole tool includes a sensor to measure the relative torque between the downhole tool and the cable in real time.
