P
assive seismic exploration methodology, in particular the
IPSS/IPDS (infrasonic passive seismic spectroscopy/infrasonic
passive differential spectroscopy) and PST/MST (passive seismic
tomography/micro seismic tomography) techniques, use spectroscopic
and time analysis of the seismic background noise acquired passively
using high sensitivity ‘very broad band’ (VBB) 3D seismometers.
Passive seismic methods are applied to study, detect and monitor
hydrocarbon reservoirs in exploration areas and developed fields.
Passive seismic is a direct hydrocarbon saturation indicator
technique; it detects the presence of subsurface hydrocarbons by
recording and analysing the low‑frequency seismic background
noise between 0.5 ‑ 10 Hz and the time domain, in order to observe
microseismic events.
The measurements can be calibrated with well data and integrated
with other geophysical data to provide information, which can reduce the
uncertainty level for drilling and field development decisions.
