Norwegian Sea - Norway - 2012

HVG2012 3D GeoStreamer®

A continuation of the GeoStreamer campaign on the Halten Terrace
Website Map for Survey MC3D-HVG2012
Expand your understanding of the geological framework and hydrocarbon potential of the Halten Terrace to the north in a mature gas and condensate province on the Dønna Terrace, covering the Revfallet Fault Complex and the Rødøy High.
The main petroleum system is characterized by a Jurassic source rock and individual Jurassic fluvial-deltaic to shallow marine sandstones and deep marine Cretaceous turbidites. These are sealed by intra-Jurassic and Cretaceous mudstones.
Halten Terrace was the first area of the Norwegian Sea to benefit from the higher structural resolution and definition provided by GeoStreamer. The dataset has been merged with the NON2010 survey to the north.
