Higher Value Data with our Acquisition Package:
Passive data provides subsurface information that cannot be achieved with traditional surface surveys.
Our data acquisition package includes active-source + passive seismic data collection and passive processing to give you a more complete subsurface image.
Our Results:
-
A better earth model derived from the complete recording of signals traversing the survey area
-
Extract rock properties not available through traditional seismic surveys
-
A better solution to near-surface statics than the refraction-based method with improved velocity model
-
Higher value data that reduces your investment risk
Our Method:
Ambient Source Technology™
-
Simultaneous recording of active-source and passive data
-
Patented survey design techniques optimize passive data collection with active-source spreads
-
Passive data processing methods used to extract velocity information from the passive data to enhance the active-source data
-
Shallow subsurface velocity model
-
Additional Analyses: Background seismicity, travel-time tomography, receiver functions
-
Processing Flow: NodalSeismic processes the passive data to generate a velocity model and static solutions. These are delivered in a form readily usable by your seismic processing vendor.
