Application Area

     Model AT25 Logging CCL is mainly used for production well logging. It measures positions of collars of casing and tubing in the production wells, water-injection wells and gas-injection wells. It can also be used to correct well depth and detect sand level in production wells.

    1. The tool is powered by a single power supply and outputs analog signals. It is characterized by stable signal output, high sensitivity, good linearity, small temperature drift and strong adaptability.
    2. It can be connected to any surface computerized logging system.
