Riphean-Palaeozoic series in the Khatanga-Lena interfluve: geological structure and petroleum potential

Khatanga-Lena region getting attention of researches for a long time, has become a focus area for intensive geological and geophysical studies both onshore and offshore. Major Russian petroleum companies have launched their exploration projects, they are: PJSC Lukoil, PJSC Surgutneftegas, PJSC NK Rosneft and JSC RNG. The paper discusses the features of geological structure and petroleum potential of Riphean-Palaeozoic sedimentary sequences within the north-eastern neighbourhood of Siberian Platform. On the results of the studies completed, the authors conclude that six promising plays are regionally developed in the study area, namely: Riphean, Upper Vendian - Lower Cambrian, Upper Cambrian, Devonian - Lower Carboniferous, Ordovician - Silurian, and Permian. The main genetic and morphological types of possible hydrocarbon traps are identified in the section of the sequences. The main and supposed oil and gas source formations are identified, their initial generation potential and degree of its realization are estimated. On the basis of all available geological and geophysical data, schemes and calculations, the schematic map of petroleum potential is created for Khatanga-Lena interfluve, and high-priority exploration target are specified in the region
