Expansion features and properties of oil and gas reservoirs of the North-Western slope of the South-Caspian basin
The paper presents reservoir properties changes in the productive strata within the limits of two anticline belts of the North-Western slope of the South-Caspian basin: Central-Apsheron and Sangachal-deniz - Duvanny-deniz - Khara-Zirya - Bulla-deniz. The results of the investigation show that in the North-Western part of the South-Caspian basin the Lower Cretaceous deposits possess satisfactory reservoir properties up to the depth of 6000 m. On the deeper levels reservoir properties of the sandy-aleurite rocks improve sufficiently due to deconsolidation and secondary processes.
