Ultra-High Resolution Seismic Imaging
Gain ultimate clarity with Extended High-Resolution (XHR) 3D seismic for a more detailed understanding of the near-surface seafloor for applications across the offshore energy industry.
UHR-3D for Offshore Energy
Ultra-high-resolution 3D (UHR-3D) technology acquisition and imaging technology, also known as extended high-resolution (XHR), provides greater clarity to the seabed and near-surface, benefiting many offshore energy industries, including hydrocarbon exploration and appraisal, wind farm development and carbon storage mapping and monitoring.
The technology uses a wide-tow acquisition configuration combined with ultra-high frequency sources, enabling enhanced resolution and true 3D.
- A flexible solution for surveying in the vicinity of infrastructure
- Can be using in shallow waters (down to 7m)
- Deep tow allows for better weather tolerance, signal-to-noise, active positioning of the spread, and system robustness
- Addresses the shortcomings of other systems such as noise, bandwidth, acoustic positioning and operational robustness
- Able to pair with ocean bottom nodes (OBN) for enhanced insight
UHR-3D for Carbon Storage
Ultra-high-resolution 3D subsurface imaging enables the initial site identification and ongoing 4D seismic monitoring of carbon storage sites through a flexible, repeatable and cost-effective solution.
-
Designed to enable geophysical early phase 3D mapping and 4D monitoring of injected CO2
-
De-risk the overburden with enhanced imaging resolution
-
Pair with ocean bottom nodes (OBN) for velocity information
- Cost-efficient, consistent repeatability
UHR-3D for Wind
Ultra-High Resolution 3D seismic provides offshore wind developers with the detailed information they need to de-risk turbine locations and intra-array cable routes.
- Reduce intrusive techniques such as boreholes
- Optimize wind farm engineering applications.
- Access ultra-high-resolution imagery. Less than 1 m vertical scale sub 100 meters depth
- Leverage geological expertise and the world’s largest subsurface data library with TGS
Additional Applications of UHR-3D
With Ultra-High-Resolution 3D seismic, we provide a detailed 3D understanding of the shallow subsurface, helping you dramatically de-risk infrastructure construction and other offshore energy activities such as site characterization, siting of jack-up rigs and marine mineral exploration.

Combining UHR-3D with with OBN
Our UHR-3D technology can be combined with Ocean Bottom Node (OBN) acquisition to complement the ultra-high-resolution imaging. Our node platform's scalability is ground-breaking and tailored to fit any survey requirement. This enables us to deploy a few hundred nodes in combination with a UHR-3D survey, which provides a cost-efficient solution.
TGS has developed a proprietary node drop and self-recovery technique. This innovative node-handling solution removes the need for an ROV vessel and allows us to use the UHR-3D vessel for node operations. This is a step change towards more cost-effective and efficient node handling solutions.
