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

CGG has a consistent regional dataset in the Northern North Sea (Norway and UK sectors) of more than 44,000 km² high-quality PSDM data. Adding to this extensive data library, CGG has acquired approximately 26,000 km² of East-West 3D data in order to provide a dual-azimuth volume over the NVG survey from the 2020-2022 seasons. The new survey includes a 1,900 km² sparse node patch West of Oseberg for additional insight.

The existing North-South data set will be reprocessed entirely, and together with the new survey, will create a dual-azimuth volume 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 improved 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.
