2nd Seabed Seismic Workshop: Imaging Innovation for the Future

About

13–15 May 2025
Kuala Lumpur, Malaysia

The last decade has seen a gradual and sustained growth in seabed seismic, mainly using ocean bottom nodes (OBN) but also ocean bottom cables (OBC) and distributed acoustic sensors (DAS). Seabed seismic has become a technique of choice and now constitutes a large portion of newly acquired seismic worldwide, and this trend is expected to continue growing for the next 15-20 years.  This growth is mainly due to two factors. The first one is the economic factor – as the acquisition and sensor technologies have evolved, the cost of data acquisition has been reduced. This continues to be the main challenge and through this workshop we will look at strategies and developments that can help to reduce the costs even further. The second is the technical factor – processing, model building and imaging using multicomponent data has evolved significantly over the last decade with new technologies being explored as well as new workflows and algorithms being developed specifically for seabed seismic datasets. Through this workshop, we will also capture the current state of these advances and lay the groundwork for the direction we hope the developments take over the next few years. Furthermore, we have seen the benefits of seabed seismic for better constrained seismic inversion, monitoring studies as well as being an enabler for the future of energy.

This workshop aims to cover all aspects ocean bottom seismic and applications from source and sensor development, novel survey designs, new algorithm development for processing, imaging, and reservoir characterization up until utilization of AI/ML and finally interpretation of these datasets. Through theoretical talks, case studies and in-depth discussions we will share our experiences from various basins around the world, in different settings and for various utilizations – from exploration scale to field focused monitoring studies.
