Get a unique insight into the structural geology and petroleum system of the Norwegian Sea with this large scale GeoStreamer dataset. The survey comprises MC3D-Q162013 and LN0902.
Late Jurassic rifting led to the formation of numerous horsts and rotated fault blocks along the margins of the Viking Graben. This area is known for its high-quality hydrocarbon reservoirs.
Coverage has been built up over several years of consistent acquisition using GeoStreamer technology. Earlier data vintages have been reprocessed and imaged in depth from original field data, using the same modern workflows to allow a unified interpretation approach through the entire volume.
