Priority directions for the development of the oil and gas complex is a systematic approach to assessing the prospects for the oil and gas potential of the regions. Based on the classification of oil systems proposed by Chinese researchers, the article discusses the characteristic features of the reservoirs of various oil and gas basins. There are three main types of petroleum hydrocarbon accumulations, which are characterized by the quality of the reservoir itself and the morphology of the traps, in combination with the corresponding indicators of hydrocarbon migration and accumulation. In accordance with the designated types of reservoirs, oil systems with their features of hydrocarbon ontogenesis are considered: source-rock petroleum system (or source system) with continuous reservoirs; an oil and/or gas oil system in tight, low-permeability rocks with quasi-continuous reservoirs and a traditional (conventional) reservoir oil system with discontinuous (discrete) reservoirs. It seems that the three oil systems under consideration can contain both a common source and several sources of hydrocarbons and from the standpoint of their formation and distribution, be genetically related to each other, i.e. be present in each pool as part of a single whole. Effective search and exploration at all stages requires comprehensive studies and various strategies taking into account the adoption of the paradigm of the integrity of the oil and gas basin in terms of the ontogenesis of oil and gas accumulations, their commonality and differences (in terms of the original source suites, migration processes, formation of traps and destruction clusters). Some information about the sedimentary basins of Australia, the Permian basin of the USA and the West Siberian oil and gas basin of Russia is given (both poor and rich in reserves and resources are used as examples). In each of the considered basins, it is proposed to assess the prospects of the territories in a comprehensive and systematic way, taking into account the classification features of oil systems.
