Viking Graben - Norway

PGS14012 3D GeoStreamer

626 sq. km of 3D broadband data in the Viking Graben
Website Map for Survey PGS14012
This dataset covers the southern flank of the Ling Graben and the northern flanks of the Jæren High stretching from the Gaupe field in the west to the Danish-Norwegian Basin in the east, forming a southern continuation of GRVLIN.
The main petroleum system is characterised by a Jurassic source rock and individual Jurassic fluvial-deltaic to shallow marine sandstones with an unknown potential in salt induced anticlines and tilted fault blocks.
The survey was acquired to further unlock exploration potential in a relatively unknown exploration area with high resolution, broadband technology
