XHR Infrastructure and Imaging
With Extended High-Resolution (XHR), we can help you de-risk the overburden and provide imaging of reservoirs. With broad-bandwidth and ultra-high resolution 3D data, the technology can potentially replace UHR 2D/3D for geohazard and site surveys
Broadband 3D Data for Renewables Risk Avoidance
With Extended High Resolution (XHR) Infrastructure, we provide a detailed 3D understanding of the near-surface seafloor, helping you dramatically de-risk infrastructure construction.
XHR is ideal for surveying the placement of offshore wind turbines, anchoring points, and jack-up rigs
Deployed in a wide-tow configuration, our Sealink 3840 recording system combines a set of ultra-high frequency sparker sources, enabling enhanced resolution and true 3D
Deep tow allows for better weather tolerance, signal-to-noise, active positioning of the spread, and system robustness
Versatile Imaging for Any Energy Projects
In addition to geohazard applications, Extended High Resolution (XHR) Imaging can provide 3D and 4D imaging for Carbon Storage and oil and gas reservoirs.
XHR is ideal for Carbon Storage Mapping and Monitoring by monitoring the development of CO2 plumes in the reservoir over time.
In order to confirm containment of stored CO2 detailed imaging of the overburden is key. XHR can help de-risking by providing ultra-high resolution images of the overburden
XHR can also be used for mapping and monitoring Oil and Gas reservoir.
Deployed in a wide-tow configuration, our Sealink 3840 recording system combines a set of air-gun sources enabling enhanced resolution and in true 3D.
XHR Imaging Combined with OBN
XHR Imaging can be combined with nodes to complement the ultra-high-resolution seismic data. The scalability of our node platform is ground-breaking and tailored to fit any survey requirement. This enables us to deploy a few hundred nodes in combination with an XHR 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 XHR vessel for node operations. This is a step change towards more cost-effective and efficient node handling solutions.
