Workshop 9
Passive Seismic Interferometry, A Key Geophysical Method for Geological Resources Exploration and Management
Monday, June 8th|
Convenors
- Thomas Kremer (Geolinks)
- Alexandre Kazantsev (Storengy)
- Aurélien Mordret (GEUS)
Description
Passive seismic interferometry is redefining how we monitor and characterize the subsurface. By harnessing ambient seismic noise, this cost-effective and sustainable technique enables 3D characterization of seismic properties and continuous monitoring of subsurface processes without the need for active sources.
This workshop will showcase recent advances and practical applications of passive seismic interferometry across key domains of interest for geological resources exploration and management. Case studies will highlight its growing role in groundwater monitoring, geological gas storage, and georesource exploration, including hydrogen, geothermal, and mining. In parallel, dedicated sessions will address ongoing methodological developments, such as accounting for noise source variability, improving the estimation of seismic attenuation, means to reconstruct body waves for enhanced subsurface sensitivity, as well as general improvements in tomography algorithms.
Bringing together experts from academia, research institutions, and industry, this workshop offers a forum to discuss both challenges and opportunities in deploying passive seismic interferometry methods at operational scales. Participants will gain insights into innovative workflows, field examples, and data analysis strategies that are shaping the next generation of seismic monitoring solutions for sustainable resource management.
Sub-Topics that will be covered in the workshop:
- Application and use cases: groundwater
- Application and use cases: geological gas storage
- Application and use cases: geological exploration (H2, geothermal, mining)
- Methodological developments: noise source variations
- Methodological developments: seismic attenuation
- Methodological developments: body waves
- Methodological developments: full waveform ambient noise inversion
