    摘要: Methods and systems for failure point diagnostics in cable telemetry at a wellsite. The methods involve providing a system includes a cable operatively coupling between a surface modem and a downhole modem that is operatively coupled to a downhole toolstring of one or more downhole tools via a toolbus. The methods further involve generating a plurality of test signals, sequentially applying the test signals across one or more test loops in the cable telemetry system, and generating a failure point alert when at least one of the test signals fails in at least one of the test loops. The failure point alert identifies which component of the cable telemetry system caused the test signal to fail.

    摘要: 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.

    摘要: Systems and methods for toolstring communication in cable telemetry. The methods involve positioning a cable telemetry system in a wellbore. The cable telemetry system can include a surface modem, a downhole toolstring of downhole tools, a downhole modem operatively coupled to the downhole toolstring, a cable operatively coupling between the surface modem and the downhole modem, and a surface data routing module that polls and trains the cable telemetry system.

    摘要: Toolstring topology mapping systems having a downhole toolstring including a master node controller and a plurality of nodes and related methods. The methods involve querying each of the plurality of nodes in the downhole toolstring for actual topology information, receiving actual topology information from each of the plurality of nodes in the downhole toolstring in response to querying, and generating a topology map of the downhole toolstring based on the actual topology information from each of the plurality of nodes in the downhole toolstring. The methods can also involve comparing the topology map with the input topology information to identify topology mismatch and then take remedial actions if needed.
