Description

The multi-component converted wave seismic market has been largely overlooked in recent years, yet it holds significant potential for improving subsurface characterization for hydrocarbon exploration and development. Multi-component data provide complementary information to conventional P-wave imaging, which can be especially useful in complex or anisotropic geological settings. With the increasing availability of Ocean-Bottom Node (OBN) acquisition systems, high-quality multi-component data have become more accessible and operationally feasible. This technological progress now enables clearer imaging in gas-affected areas, improved anisotropy analysis, and reduced subsurface uncertainty, ultimately supporting better drilling decisions and higher success rates.

Sub-Topics that will be covered in the workshop:

This workshop will cover the full workflow from acquisition and processing to inversion, to improve subsurface characterization through converted-wave imaging, particularly when integrated with P-wave data.

Key topics will include:

  • Wavefield separation
  • Denoising
  • Event picking and imaging
  • Tomography and Full-Waveform Inversion (FWI)
  • Stratigraphic inversion

 

These topics will be illustrated with case studies highlighting the added value of converted waves in complex geological settings.

Contributions are welcome across all areas, including acquisition strategies, methodological developments, case studies, and novel algorithms for converted-wave data processing.

Participant Profile

This event is designed for researchers, both from industry and academia, practitioners, and students seeking to deepen their understanding of the added value of converted waves in enhancing subsurface imaging.

We invite participants to share their experiences, both success stories and challenge, through case studies for group discussion. These case studies may include business objectives, feasibility assessments, workflows, interpretation results, and remaining uncertainties.
