South-West Barents Sea: New Opportunities from the Atlantic Margin

Paolo Esestime (Spectrum) uses Spectrum’s modern 3D multi-client seismic, in the SW Barents Sea, to highlight additional hydrocarbon prospectivity in Cretaceous-Paleogene plays. These 3D seismic campaigns, undertaken in 2011–2012 and 2016, have resulted in a comprehensive dataset which will generate new hydrocarbon prospects and raise the commercial profile of the most developed area in the Norwegian Barents Sea.

The Western Barents Sea has seen the highest rate of exploration success in all the Norwegian Barents Sea; it also includes active production facilities and future plans for development.

Successful hydrocarbon exploration in the Barents Sea relies on several hydrocarbons plays, laterally stacked in different basins, and vertically distributed in a variety of reservoirs. Triassic-Jurassic sands are historical targets for oil and gas; however, the recent discoveries of Gotha and Neiden have proved good reservoir properties even in Permian-Carboniferous carbonates.

The westernmost margin is currently considered a new venture area, where gas sands have been already found from the Cretaceous to the Paleogene.


Spectrum’s modern 3D multi-client seismic coverage over the Western Barents Sea allows detailed analysis of the petroleum system elements resulting from Atlantic margin processes. This highlights significant additional hydrocarbon prospectivity in relatively unexplored
Cretaceous-Paleogene plays proven in other sectors of the Atlantic Margin in Norway and UK.
