OBS Technology Solutions in Intermediate & Deep Waters
Seabed Geosolutions offers several solutions in intermediate to deep waters utilizing the following versatile ocean bottom seismic (OBS) technologies:
- Manta® OBN - A single node technology for depths from 0 - 3000 meters - Manta is the evolution of seabed seismic technology. A single node system for all depths and environments. Simplified, automated, safe and versatile, it goes where traditional streamer seismic can’t. To learn more, visit the Manta webpage.
- Sercel SeaRay® OBC – For intermediate water depths to 300 meters - Seabed Geosolutions offers the Sercel SeaRay ocean bottom cable (OBC) system with which we can acquire exploration 2D, high-density 3D or development 4D programs with digital broadband sensors. Sercel SeaRay is an integrated multi-component 4C receiver with 3C Digital Sensor Unit (DSU) and one hydrophone providing improved sensor coupling and vector fidelity. One benefit of an OBC system such as Sercel SeaRay is its ability to provide real-time continuous seismic data recording and QC, unlimited by battery life.
- CASE Abyss® and Trilobit® OBN – ROV placed nodes ideal for intermediate to deep waters up to 3000 meters - There are occasions where towed streamers, ocean bottom cables, or shallow water cabled systems will have restricted access for imaging the subsurface. In these circumstances, we offer several proprietary ocean bottom node systems including Trilobit and Case Abyss ocean bottom nodes (OBN) technologies. Seabed Geosolutions nodes not only incorporate four component (4C) broadband surveys, but their flexibility also makes them ideal for obstacle avoidance or imaging in environmentally sensitive locations. Prolonged recording endurance and versatility in deployment method make our node solutions a highly viable option for challenging environments, as well as for enhanced subsurface imaging. CASE Abyss and Trilobit node systems’ 4C technology and proprietary design offer enhanced coupling to the seafloor, stability and reduced noise compared to streamer seismic acquisition. CASE Abyss’ externally planted sensor provides controlled planting for maximum ground coupling and vector fidelity. The Trilobit node’s ridged bottom faceplate offers stability and reduced noise in a compact and modular unit. Both systems provide a high signal-to-noise ratio.
Clearer, quieter data provide for easier multiple removal during processing and better subsurface imaging to help make well-informed decisions for the next step in field development.
