OBN

Ocean Bottom Node (OBN) seismic acquisition delivers high-resolution, full-azimuth imaging by placing autonomous nodes directly on the seafloor to capture detailed subsurface data. Designed for complex and technically demanding environments, OBN surveys provide clearer reservoir insight, improved structural definition and greater confidence in exploration and field development decisions. 

With more than 20 years of OBN experience and over 130 surveys completed worldwide, TGS combines proven nodal technology, automated handling systems and integrated project workflows to deliver predictable, high-value outcomes. Our modular MASS and ZNodal systems operate from shallow water to 4,000 meters depth, supporting safe, efficient deployment across diverse offshore settings — from infrastructure-led exploration to reservoir monitoring, CO₂ storage and marine resource projects.

Through our ECHOVA integrated workflow, we connect planning, acquisition and processing into a streamlined, transparent execution model. This end-to-end approach reduces operational risk, improves environmental performance and ensures consistent data quality, helping clients move forward with clarity, accountability and confidence.

UHR3D

2025 Ramform Atlas Hywind Tampen Windfarm - straight and crop

UHR3D

Ultra-High Resolution 3D seismic delivers precision imaging of the shallow subsurface, providing exceptional clarity of near-seafloor conditions. Using short streamers, shallow tow depths and high-frequency sources, UHR3D captures fine-scale geological features that are critical for offshore wind development, infrastructure planning and complex site investigations. 

Fully imaged 3D data volumes provide consistent spatial detail across compact or congested marine environments, improving detection of geohazards, soil variability and buried obstructions that conventional 2D or sparse 3D methods may overlook. Optimized for smaller survey areas and shallow targets, UHR3D supports early-stage decision-making with reliable, high-resolution subsurface insight. Advanced processing workflows including deghosting, statics correction and high-resolution velocity model building ensure data consistency and vertical precision down to a few meters. The result is a clear and actionable understanding of shallow geology that reduces uncertainty, improves design confidence and supports efficient project execution across offshore energy, wind and carbon storage developments.

Azimuths
Multi-Azimuth

Multi-Azimuth

Multi-azimuth, multi-sensor towed streamer configurations, deployed with single or multi-vessel wide-tow sources, address complex clastic and subsalt imaging challenges while providing an economic solution for richer seismic illumination and improved velocities. By tailoring azimuth acquisition to subsurface complexity, additional azimuths can enhance target illumination, improve lateral resolution and strengthen coherent noise attenuation. From cost-effective single-vessel multi-azimuth surveys to wide-azimuth and rich-azimuth multi-vessel geometries, acquisition design is optimized to balance geophysical objectives and project economics. 

Multi-azimuth acquisition improves subsurface characterization in clastic and carbonate environments and can be applied to new surveys or integrated with legacy narrow-azimuth data for rapid upgrades. Wide-azimuth and rich-azimuth geometries expand offset and azimuth diversity to enhance imaging beneath complex overburdens such as salt, while extended long-offset strategies strengthen Full Waveform Inversion and velocity model building. In the most demanding environments, hybrid acquisition approaches combining towed streamers and ocean bottom nodes further enrich offset and azimuth coverage to support advanced inversion and elastic property analysis.

The result is improved reservoir delineation, reduced uncertainty in amplitude and inversion workflows, and clearer subsurface understanding across exploration and field development projects.

3D

2D-cubed

2D-cubed seismic volumes transform dense 2D lines into a structurally conformable 3D volume at regional or basin scale, enabling 3D interpretation where 3D coverage is sparse, at close to 2D cost. By integrating multivintage 2D and selected 3D data into a unified dataset, 2Dcubed creates an interpretable 3D volume that unlocks the full capability of modern 3D interpretation software for regional screening and play evaluation.

The workflow demigrates and matches existing data for amplitude and phase consistency before applying dip and coherency-guided interpolation to generate a continuous 3D volume. The resulting dataset is 3D migrated and optimized for regional structural interpretation, helping validate the gross structural framework, identify prospective trends and guide future 3D survey design. While smaller-scale features still require conventional 3D acquisition, 2Dcubed provides a cost-effective solution for basin-scale screening and portfolio evaluation.

With more than 2.3 million square kilometers processed globally across diverse basins, 2Dcubed has proven its value as a regional decision-support tool, enabling companies to prioritize acreage, reduce exploration risk and communicate geological plays with greater clarity.
