Abstract
Systems, methods, and computer-readable media for downhole line detection. A system can send an electrical signal down an electric line that runs down an outside of a downhole casing of a wellbore. A downhole sensor system located at a downhole location inside the downhole casing can detect a magnetic field generated by a current of the electrical signal. Next, the system can identify a one or more characteristics of the magnetic field and/or the electrical signal. Based on the one or more characteristics, the system can determine a first position of the electric line relative to the downhole casing or the downhole sensor system. The system can then infer, based on the first position of the electric line, a second position of a non-electroconductive cable that runs alongside the electric line outside of the downhole casing of the wellbore.
