pdf  Paleozoic section of the sedimentary cover of the East Siberian Sea’s northern outskirts and its importance to petroleum potential assessment
A section of regional seismic profile crossing the shelf of the East Siberian Sea from Wrangell Island to Mendeleev Uplift made in accordance with modern technologies is analyzed. It was found that the platform cover of the region includes not only the Upper Cretaceous and Cenozoic rocks with thickness up 0.5-1.5 km, as previously believed, but also two Late Paleozoic - Mesozoic sequences with a total thickness not less than 4-5 km. It was concluded on the basis of speed waves characteristics analysis and regional comparisons that petroleum generating potential preserved even into the lowest part of these strata. Carbonate levels characterized as favorable reservoir buildings of cavernous type are identified in this section. It is shown that the use of light modification of seismic survey in the region leads to partial coverage of the sedimentary section and to petroleum potential under-estimation.

Keywords: sedimentary cover, Upper Paleozoic, carbonate rocks, petroleum potential prospects, East Siberian Sea.
