The main objective of the GeoBase project is to produce a set of refined tectonostratigraphic and paleogeographic models for the Barents Sea and Kara Sea hydrocarbon provinces. The project involves the synthesis of existing Russian and Norwegian geological and geophysical datasets and their interpretation using an interdisciplinary approach. By combining potential field data and selected seismic lines, further calibrated with deep and shallow boreholes and surrounding outcrops, the project has produced an integrated tectonic, structural and paleogeographic framework for the Barents Sea, northern Pechora region and Kara Sea areas. Such an integrated study is crucial and an obvious scientific way for understanding the spatial distribution of hydrocarbon source rocks and potential reservoir rocks as a base for identifying and valid the most promising petroleum plays concepts in the Barents Sea.
The study has provided a refined geological fundament for the crustal pattern and basin architecture of the Barents Sea - Kara Sea region, and the difference in the basins characteristics from the Western Barents Sea to the Eastern Barents Sea is better constrained. A series of 20 new paleogeographic maps spanning from Devonian to Eocene has been produced. The maps provides more high-resolution paleogeographic models compared to previous published maps from the region and serve as useful means for understanding the lateral distribution of the main sedimentary in the studied areas.
