TGS now offers more than 21,500 km2 of GSX multi-client seismic data, which provides a modern, high-resolution foundation for development, ILX and TLX exploration activities across one of Norway’s most prospective offshore regions.
TGS now offers more than 21,500 km2 of GSX multi-client seismic data, which provides a modern, high-resolution foundation for development, ILX and TLX exploration activities across one of Norway’s most prospective offshore regions.
The GSX program delivers a high-density dual azimuth solution that complements existing GeoStreamer coverage, said TGS. Designed to resolve long-standing imaging challenges on the Halten Terrace, the dataset enables clearer interpretation of complex structures and identification of remaining prospectivity, the company added.
The Halten Terrace features high-quality hydrocarbon reservoirs within a structurally intricate setting shaped by Late Jurassic rifting, said TGS. Resulting horsts, tilted fault blocks and Cretaceous basin floor fans represent diverse play types that benefit from enhanced illumination and broadband fidelity, the company added.
To achieve this uplift, the GSX campaign applied multi-sensor broadband technology, dual azimuth illumination, wide tow sources, dense streamer spacing and long streamers for robust velocity model-building. The result is a dataset that significantly improves fault definition, structural imaging and reservoir characterisation, said TGS.
