SNS2013M 3D

Modern 3D seismic data in an exciting frontier exploration zone
Website Map for Survey MC3D-SNS2013M
Extending 3D coverage to the north of the Southern North Sea gas province and frontier acreage on the Mid North Sea High, this modern dataset provides a new tool to expand understanding of the geological framework and hydrocarbon potential.
The main petroleum system is characterized by a Carboniferous source rock and individual Carboniferous to Lower Permian fluvio-deltaic reservoir sandstones, sealed by Zechstein evaporites. Additional post-salt discoveries are situated in Triassic sandstones, typically onlapping on Zechstein diapirs.
The introduction of a new 3D dataset over the Mid North Sea High provides an invaluable tool to research new sub- and supra-salt plays to the north of the main Permian basin and to better characterize the existing leads, including Carboniferous structures and an inferred Permian carbonate play.
