Abstract
A digital structural model of sedimentary complexes in the Laptev sea allows us to trace and identify the boundaries of sedimentary basins and assess the scale and conditions of sedimentation, as well as to predict the areas of development of oil and gas source strata, collector and reservoirs. The generated basins model was detailed by selecting GAUS elements in it. In the central and southern part of the Laptev Sea basin, gas deposits are expected in all complexes, which is due to the increased heat flow and, as a result, a high degree of transformation of the oragnic substance of the oil and gas source rocks. Analysis of the results shows that a significant hydrocarbon potential is expected in the Paleogene clinoforms of the Eastern Arctic. At present, this complex is undervalued and additional study, including detailed mapping of its internal structure, is required for resource assessment.
