Abstract
Systems, apparatuses, and methods for hybrid cable telemetry. The methods can include positioning a toolstring in a wellbore. The toolstring can include an uphole telemetry cartridge and a downhole telemetry cartridge respectively adapted to send and receive telemetry data. The toolstring can also include a hybrid logging cable having optical fibers and copper conductors that can operatively couple the uphole telemetry cartridge to the downhole telemetry cartridge. The method can also include transferring data between the uphole telemetry cartridge and the downhole telemetry cartridge across the optical fibers and the copper conductors. The method can further include measuring a data transmission rate on the optical fibers and the copper conductors. The method can also include comparing the data transmission rate to a predetermined threshold. The method can further include detecting a data transmission failure when the data transmission rate falls below the predetermined threshold.
