Geological Evolution and Trapping Mechanism of the North-West Barents Sea Continental Margin

Based on seismic, magnetic, gravimetric, literature data and on geological knowledge main tectonic events which had place in Paleozoic, Mesozoic and Cenozoic history in the Western Barents margin were determined. Seismic stratigraphic method was involved in interpretation of the seismic data. Six seismic stratigraphic complexes were outlined by seismic data. Main tectonic events (uplifts) were tied to regional unconformities traced by seismic. Main thickness of the sedimentary cover in the studied area is represented by Cenozoic deposits. Paleo geological profiles and paleo geographic maps were built for main tectonic events in Cenozoic. It helped to build geological model of the studied area. Perspective reservoirs in the sedimentary cover of the Western Barents margin were outlined in both Paleozoic-Mesozoic and Cenozoic stratigraphic intervals. Main oil and gas potential related to Paleocene – Lower Oligocene and Miocene reservoirs.
