Norwegian Sea - Norway - 2013

HVG2013 3D GeoStreamer®

High quality data for higher structural resolution and definition
Website Map for Survey MC3D-HVG2013
Expand your understanding of the geological framework and hydrocarbon potential of this mature province with this dataset covering the southern part of the Halten Terrace and the Grinda Graben.
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. The broadband seismic enables clear stratigraphic and structural definition of the Jurassic and Cretaceous targets.
Halten Terrace was the first area of the Norwegian Sea to benefit from the higher structural resolution and definition provided by GeoStreamer technology.
