Details
While OBN acquisitions have clearly contributed to superior P-wave imaging compared to streamer data, leveraging the recorded converted waves remains more challenging. In this context, we explore the opportunities and recent advancements in converted-wave imaging, particularly when integrated with P-wave data. Our objective is to review key elements of this workflow—from wavefield separation, denoising, and picking, to imaging, tomography, full-waveform inversion, and stratigraphic inversion. These methodologies will be illustrated through a series of case studies, highlighting the added value of converted waves when combined with P waves to enhance subsurface characterization and improve imaging in complex geological environments.
