What is Noise Logging?

• A noise log is simply record of a passive measure of the audible sound detected by a sensitive hydrophone at a number of locations in the wellbore.
• Because sound is generated by fluid turbulence, high noise amplitudes indicate location where the flow path cause additional turbulence to develop mostly like:
  • Fluid movement through restricted channel
  • Leaks
  • Flow from perforation
  • Flow Past the logging sonde
