Northern Viking Graben

Mitigate near-field risk in the Northern North Sea with a new dual-azimuth volume

Viridien has a consistent regional dataset in the Northern North Sea (Norway and UK sectors) of more than 44,000 km2 high-quality North-South PSDM data. Adding to this extensive data library, Viridien has recently acquired more than 28,000 km2 of East-West 3D data to provide a dual-azimuth volume. The latest additions to complement the NVG survey include new NVG Hybrid data, which showcases an innovative approach to optimizing full-waveform inversion (FWI) through sparsely distributed nodes combined with streamer acquisition, and the 2024 NVG EW data, which builds on the current east-west (EW) streamer coverage in the Norwegian North Sea.

These datasets are readily available to:

  • Identify and de-risk near-field exploration targets
  • Aid maturation of stranded discoveries towards development
  • Enhance the imaging of multi-directional fault patterns
  • Provide enhanced resolution to resolve complex reservoir stratigraphy

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.
