  • Recently, TGS delivered more than 120,000 km regional broadband data offshore Portugal (left) and in the North Sea (right).

Clari-Fi™ is a broadband processing package which includes denoising, deghosting, designature and inverse-Q. A multi-domain denoising process attenuates various types of noise before the deghosting algorithm accounts for the local variations of source and receiver depths and the sea state. A global statistical approach is then used to address the source signature in different directions, before Q compensation with respect to the ray-paths. The resulting high quality broadband data improves visual and quantitative interpretation.
