Title: Developments and Applications in Near-surface Seismology
Room: Schubert 1
Convenors: Claudio Strobbia (Total)
Charlotte Krawczyk (Real Time Seismic)


Workshop description

*If you are interested in attending the workshop, make sure to register as soon as possible via the following webpage.

The workshop will discuss the specific acquisition geometries and strategies to acquire active and passive seismic data for reflection, refraction and surface wave applications, with single component and multi-component data, as well the possibilities and strategies for multipurpose acquisition.

The synergies between the multiple datasets will be explored; the joint inversion of multiple measurements will be discussed. The workshop focuses on mining, engineering and environmental applications, as well as on the oil and gas exploration, for which the near-surface modeling is discussed as part of the land seismic processing and for shallow hazard identification.

The topics that will be discussed comprise:

  • Recent advances in acquisition technologies for near-surface applications,
  • Use of multicomponent data for shear-wave characterization and imaging,
  • Use of shear waves and converted waves in shallow applications,
  • Challenges in data collection and integration for combined shallow and exploration applications,
  • Evolution of surface wave testing to 2D and 3D,
  • Estimation of anelastic properties,
  • Applications of full-waveform inversion,
  • Role of passive data in mapping near-surface anomalies, and 
  • Impact of the near surface perturbations in passive seismic processing.
