Due to the oil and gas prospects of the deep layers in Azerbaijan, a large amount of geological prospecting and geophysical work has been carried out recently, and scientific criteria have been developed that could be the basis for future exploration. It was noted that the main oil and gas fields are associated with the South Caspian and Kura basins, which were intensively buried during the Mesoceneozoic. Although researchers have no doubt that these sediments are highly promising in the central part of the basin and in the deeper layers in general, a quantitative or quantitative expression of the problem has not yet been found. It is known that exploration, production and assessment of potential in oil and gas fields is highly dependent on the collected information about the petrophysical characteristics of the layers, found in the geological profile.
 

The article presents a comparative analysis of deep reservoir rocks based on petrophysical studies conducted in the South Caspian Depression, the Kuran Depression and the Caspian-Guba oil and gas region. Analysis and interpretation of geological and geophysical and petrophysical data revealed that oil and gas reservoirs are mainly in volcanic-sedimentary and carbonate rocks. Briefly, the petrophysiological mapping of rocks drilled from exploratory wells in the area has been clarified. Summarizing the data obtained, it can be concluded that a large-scale change in the reservoir properties of field conversations is due to their lithological diversity and thermobaric conditions at depths.
 

Given the oil and gas prospect of this region, the presence of unexplored local deposits and the possibility of the appearance of new oil and gas fields in them, the study of the geological structure and collective features of the field when determining promising structures and objects of the oil and gas complex is an important problem.
