Recent years have seen the discovery of over 50 local structures on the Laptev Sea shelf. Facies variations and intricate architecture of sedimentary sequences, their partition by displacements of complex kinematics determined the formation of different types of hydrocarbon traps. The evidence obtained from the seismic stratigraphic and seismic facial analysis as well as the structural mapping based on 2-D CDP reflection data has revealed the presence of structural, lithologic, lithologic/stratigraphic and combination hydrocarbon traps. The presented subdivision of hydrocarbon traps provides the basis for more efficient exploration during the early stages of studying exploration targets.

Key words: sedimentary basin, seismic sequence, displacement, strike-slip, normal fault, reverse fault, horst, graben, hydrocarbon trap, oil and gas play, oil and gas accumulation zone.
