Central Graben - Denmark - 2013

TEG2013 3D GeoStreamer®

High quality 3D data are key to unlock new play potential
Website Map for Survey MC3D-TEG2013
Targeting the Danish Central Graben over the Tail End Graben, the Coffee Soil Fault and onto the Ringkøbing Fyn High, this survey provides the first 3D images of the area.
The Danish Central Graben is a mature and prolific area with discoveries in Late Jurassic sandstones and Cretaceous chalk and limestones. The dataset reveals a potential new play of Permo-carboniferous age in a previously poorly imaged basin east of the Coffee Soil Fault.
This high-density, broadband GeoStreamer dataset provides fresh insight into the structures in this area.
