Brief results of geological exploration for oil and gas within the Lena-Anabar trough and Anabar-Khatanga saddle are presented. The extremely low and uneven level of geological and geophysical study of the territories under consideration and the need to study the Middle Paleozoic complex of sediments are noted. Based on the published and archive information, a brief overview of lithological and stratigraphic descriptions of sections and features of the geological structure of the Middle Paleozoic deposits of the studied territory is made. A paleogeographic diagram of the Middle Paleozoic rift complex of the Laptev plate and the adjacent territory were constructed. The data indicating the oil-source properties of the Devonian deposits within the Anabar-Khatanga saddle are presented. On the basis of geological and geophysical data, an assumption is made about the presence of saliferous deposits in the section of the Kyutyungda graben. The possibility of realizing the oil-source potential of the Vendean-Cambrian deposits in the lower part of the section of the Kyutyungda graben is indicated. The prospects of oil and gas content of the southern part of the Laptev Sea shelf related to the Middle Paleozoic deposits are predicted.

The paper deals with the issue of regional gas content of Nejelinsky formation of the Lower Triassic. Based on the consideration of the peculiarities of the gas content of Nejelinsky formation and the upper productive horizons of the Permian age within the Khapchagai megawall, it is concluded that there are two types of deposits in the section of Nejelinsky formation. The rst type of deposits is gas-hydrodynamically limited in the volume of Nejelinsky formation and is genetically related to breakthrough gases from the Permian part of the section. The second type of deposits is gas-hydrodynamically related to deposits in the upper part of the Permian productive horizon. Due to the lack of its own gas formation potential in Nejelinsky formation outside the Khapchagai and Loglorsky shafts, it can only be considered as an e ective uid barrier. It is concluded that in the absence of isolated deposits in Nejelinsky formation, favorable reservoir properties in the Permian part of the section should be expected.
