Ambient Source Technology™

NodalSeismic's Data Acquisition Services:

• Simultaneous Recording of Active-Source and Passive Seismic Data
• Passive-Only Surveys: Upgrade Previous Active-Source Surveys
• Passive Data Processing
• Passive Monitoring and Induced Seismicity Surveys
• Cable-Free Acquisition

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.
