Description
Retrieving responses between receivers or sources is the base of seismic interferometry. One of the main applications is in passive seismics, e.g., the possibility of using ambient-noise records instead of performing costly active seismic acquisitions.Another application is of using already acquired active-source data for retrieval of complementary arrivals. One of the main purposes of application of seismic interferometry is for building velocity models, which can be interpreted in terms of geological structures or used for other applications (e.g., statics computation, FWI, etc.), and imaging with retrieved reflections. But later advances show the possibility of performing reservoir monitoring, determining attenuation parameters, suppression of surface waves, retrieval of first breaks, etc.
This workshop intends to connect practitioners applying seismic interferometry at different scales with different objectives. Participants will contribute case studies, highlighting both the successful and the challenging aspects of their work, and share ideas on the latest algorithms and applications.
Participant Profile
This workshop is addressed to those who want to show their latest advances on this topic for different fields of application such as energy, CO2 storage, mineral exploration, engineering and environmental, global seismology.
