Seismic Interferometry: New Advances and New Applications

Date: Monday 5 June 2023

 

Convenors

  • Ilaria Barone (Università degli Studi di Padova)
  • Deyan Draganov (TU Delft)

 

Description

Retrieving responses between receivers or sources is the base of seismicinterferometry. One of the main applications is in passive seismics, e.g., the possibilityof using ambient-noise records instead of performing costly active seismic acquisitions.Another application is of using already acquired active-source data for retrieval ofcomplementary arrivals. One of the main purposes of application of seismicinterferometry is for building velocity models, which can be interpreted in terms ofgeological structures or used for other applications (e.g., statics computation, FWI, etc.),and imaging with retrieved reflections. But later advances show the possibility ofperforming reservoir monitoring, determining attenuation parameters, suppression ofsurface waves, retrieval of first breaks, etc.

This workshop intends to connect practitioners applying seismic interferometry atdifferent scales with different objectives. Participants will contribute case studies,highlighting both the successful and the challenging aspects of their work, and shareideas 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.
