Highly sensitive ground motion velocity receivers; gas reservoir1-s or 2-s
<1000 V/m/s
The signals weaken at the rim of the reservoirs and are not observed outside the reservoir area.
Seismic-acoustic background noise differs widely.

16Passive seismic low frequencyLow frequency microtremors [4]Tight gas reservoir and an adjacent exploration area1500 V/m/sRequiring careful data analysis using microtremors around reservoirs with considerable noise (e.g., production noise) because (a) anomalies caused by noise can be misinterpreted as being caused by the reservoir or (b) such a high-noise environment can overwhelm the signal.
