Northern Viking Graben

Reduce Near-Field Exploration Risk in the Northern North Sea with Dual-Azimuth Coverage

Viridien provides a comprehensive regional dataset spanning over 44,000 km² of high-quality North-South PSDM data across the Northern North Sea, including the Norwegian and UK sectors.

Building on this substantial data library, Viridien has recently acquired more than 28,000 km² of East-West 3D seismic data, enabling the creation of a dual-azimuth volume. This includes the NVG Hybrid dataset, which features an advanced acquisition approach that integrates full-waveform inversion (FWI) using sparsely distributed nodes alongside traditional streamer data.

Further expansions to the NVG survey in 2024 included new East-West data and sparse node acquisition, extending coverage into the Norwegian Sea and Møre Basin—further enriching the regional seismic offering.

NVG Dual Azimuth

New East-West acquisition is being combined with a full reprocessing of the underlying NVG North-South data to generate a dual-azimuth seismic data set.

Innovative, hybrid acquisition for greater uplift

The NVG Hybrid seismic dataset, covering the Oseberg and Martin Linge fields, optimizes full-waveform inversion (FWI) through sparsely distributed nodes in combination with streamer acquisition. By applying time-lag FWI (TLFWI) using offsets up to 60 km, we have greatly improved our velocity modeling and imaging capabilities of deeper and more complex subsurface targets.
