Covering the northern North Sea, including several large oil and gas discoveries such as Statfjord, Gullfaks, Oseberg and Brent, this large merged and reprocessed 3D survey also includes Visund, Gimle and Veslefrikk.
The main reservoir units in the area are Early to Middle Jurassic sandstones with a Jurassic source rock. Triassic reservoirs are seen in the northern part of the area, while Cretaceous and younger plays are less explored.
This conventional dataset was reprocessed from field data in 2013 and is available in both time and depth.
