Viking Graben - UK/Norway - 2012

Q16UK2012 3D GeoStreamer®

De-risk future exploration and extend production of existing fields
Website Map for Survey MC3D-Q16UK2012
The Q16-2012 GeoStreamer survey was acquired over the key southern extension of the Brae trend in the South Viking Graben (e.g., Larch, Sycamore, Thelma). Furthermore, it extends coverage westwards onto the Fladen Ground Spur (East Shetland Platform) and eastwards into the Gudrun Sub-Basin.
Both reservoir and source rocks for the main fields were formed during the Late Jurassic rifting. To the west, the fields follow the fault-bounded Brae trend; in the depo-centre, discoveries are located within fault blocks (J1). Clear Devonian reflectors on the platform provide additional potential.
Q16-2012 GeoStreamer provides an invaluable tool to de-risk future exploration, whilst providing the key dataset to extend production of existing fields. It also allows for a greater insight into the structural history and prospectivity of the Fladen Ground Spur and South Viking Graben.
