Spectral Noise Log – SNL

images-pages-simulation1
Spectral Noise Log (SNL) is a very powerful tool designed to record sound in frequency range of 8 Hz to 60 kHz. SNL’s super sensitive hydrophones detect any small fluid noise even behind multiple barriers of pipes and cement in the wellbore and this has made it as an excellent solution for source identification in Gas Migration (GM) and Surface Casing Vent Flow (SCVF) in Canada.
SNL enables locating the source of small leaks by identifying the cross-flows, lateral flows and cement channels behind multiple casing barriers.
