Abstract: A system and method to minimize the likelihood of cable damage due to downhole operations such as perforating is disclosed. The system includes at least one transducer and at least one orientation device positioned adjacent a cable. A wireless signal from the transducer and/or orientation device is transmitted towards the cable. The wireless signal influences a wired signal transmitted in the cable. The influenced wired signal is used to identify the axial and radial orientation of the cable. The transducer may be secured to a mid-joint collar on the casing string in a portion of the wellbore to be perforated. The transducers are identified and located by the control system and a perforating tool can be adjusted to point away from the cable before firing of the perforating tool.
