Evaluation of Downhole Electric Components by Monitoring Umbilical Health and Operation |
| 摘要 |
A method for monitoring a condition of a downhole system, the method comprising: delivering an electric signal to a downhole electric device via a downhole power transmission cable from a signal generator; receiving an electric response signal from the downhole power transmission cable; comparing the electric signal to the electric response signal to determine the location of a defect in the downhole system; and predicting a type of the defect based on said location, wherein the electric signal comprises one or more voltage pulses. |
