PGS16004 3D GeoStreamer

De-risk exploration in an underexplored area with broadband technology
Website Map for Survey PGS16004
The survey covers the Nyk High, Vema Dome, part of the Vigrid and Någrind synclines and the Hel Graben. It will offer full 3D AVO-compliant coverage to promote the exploration potential in this underexplored area with recent discoveries and the development of the Aasta Hansteen field.
Several gas discoveries have been made on the Nyk High, such as the Haklang, Snefrid, Gymir, Roald Rygg and Ivory. The primary reservoir sandstones are the deep marine fans of Cretaceous age such as the Kvitnos, Nise and Springar formations.
GeoStreamer is true broadband achieved through dual-sensor acquisition and the latest and best processing workflow. This survey is designed to unravel the many structural and stratigraphic traps in the Cretaceous.
