10. Spectral Noise Logging Type Library
kHz 1 3 10 20 30
Here is so called SNL type library – the typical SNL spectrum recorded in wide frequency range from low frequencies starting from 8 Hz to high frequencies up to 60 kHz. It contains all kind of noises from different sources and therefore provids the full picture of what going on around the sensor.
Based on the lab and filed experiments, the each type of noise can be distinguished as per their unique frequency pattern.
Here is a typical pattern for borehole flow noise,
for noise produced by flow through channels in cement.
The noise produced by matrix flow is localized in frequency, has a good correlation with permeability profile and is usually characterized by high frequencies (from 3 to 30 kHz) depending on rock quality index.
Fracture flows are seen as a localized noise in the lower frequency window than matrix flows.
