Results of studying the zones of oil and gas generation of the junction zone between tectonic structures of the southern part of the Laptev Sea and the Siberian Platform

In order to evaluate the oil and gas potential of the junction zone between tectonic structures of the southern part of the Laptev Sea and the Siberian Platform, the pods of active Upper Riphean, Vendian, Permian, Devonian and Upper Jurassic source rocks were identified and studied using numerical modeling methods. The impact of major tectonic shifts that occurred in the region during the second half of the Paleozoic and Mesozoic eras on the evolution of the source rocks was assessed. It was found that, except for the Upper Jurassic, all of the studied source rocks had passed the critical moment before the completion of major tectonic events in the region, which negatively impacted the formation of the hydrocarbon potential of the study area. As a result, low prospects are anticipated in the continental part of the junction zone, where small deposits are expected in the Vendian strata of the Lena-Anabar trough, given the presence of seals. A significant hydrocarbon potential, warranting further oil and gas exploration studies, is forecasted in the southern part of the Laptev Sea and the adjacent coast within the AnabaroKhatanga saddle. The primary exploration opportunities in this region are linked to Permian and Mesozoic deposits.
