GEOSPECTRA IPDS® VERSUS 2-D/3-D SEISMIC
GEOSPECTRA IPDS®
Seismic
Passive method (non invasive)
Active method (highly invasive)
Detecting natural signals
Detecting induced signals
Micro-seismic / acoustic spectroscopy
Seismic refraction & reflection (travel time and amplitude)
No dispersion, no refraction, no absorption
High dispersion, high refraction, high absorption
Low frequency 0.1 - 8 Hz
High frequency > 10 Hz
Seismometer – high sensitivity
Geophone – low sensitivity
Detecting hydrocarbon fluids
Detecting shape of rock formation (structure)
Determine total net oil column
Determine depth of structures
Quick and accurate results with time and money savings
Time and money consuming in complex areas
GEOSPECTRA IPDS® direct hydrocarbon detection method
complements seismic data
