As a result of a thorough analysis of geophysics data and deep drilling, it was established that the most likely zones for the discovery of new oil and gas reserves are localized in the north and center of the Pre-Verkhoyansk trough, as well as in the southeastern part of the Siberian platform along the Aldan-Maya trough. The high content of hydrocarbons in the formation waters of productive layers indicates large-scale processes of gas formation and active vertical and horizontal migration, which contributes to the creation of a favorable environment for the formation of free gas. Particular attention is drawn to deposits in Jurassic deposits, formed due to the secondary capture of gas ows during intense vertical and inter-reservoir movement. The key reservoirs for future discoveries are the sandy-clayey Permian deposits under the clayey strata of the Lower Triassic Nedzhelin Formation. Most proven gas reserves are associated with large, high-amputation swell-like uplifts. Modern geological structures and the hydrodynamic potential of the region determine optimal conditions for the migration of hydrocarbons. It is proposed to designate the Kitchanskaya, Yakutskaya and Munskaya zones of expected oil and gas accumulation as priority objects in the central part of the Pre-Verkhoyansk trough and adjacent territories of the Vilyui syneclise. The article examines the oil and gas potential prospects of the Aldan-Maya trough. Here, buried landforms play a key role in geological structures and determine the prospects for the generation and migration routes of hydrocarbons, in the structure of lithological-stratigraphic traps. The industrial signi cance of deposits contained in Riphean sediments has been con rmed in adjacent territories, in particular within the Berezovskaya depression.
