DEEP FILTRATION AND CAPACITY PROPERTIES OF RESERVOIRS OF OIL FIELDS IN THE SOUTH CASPIAN BASIS

The relevance of research on the western edge of the South Caspian Basin (SCB) is explained by the fact that the main, actively developed offshore fields of the Absheron and Baku archipelagos are concentrated here. Each of these archipelagos contains large and well-known oil and gas fields, such as the "Neft Dashlari", Chilov, Sangachaly, Duvanny, Bulla, Alyat, and others. However, in all of these structures, the primary production complex is primarily the Productive Suit (PS). It has been established that the PS productive horizons are characterized by high reservoir and filtration properties, as well as by the geological structure of the section, which provides uniquely favorable conditions for the generation and accumulation of hydrocarbon deposits. Given this, the objective of the issues addressed in this article is to identify deep variations in the reservoir and filtration-capacity properties of oil-and-gas-bearing sediments and assess the possibility of detecting hydrocarbon accumulations at critical levels in the SCB section.
