Study of natural reservoir sedimentary environment at western flank of South Caspian depression

Based on the study of core material, the article proposes a new method for facies analysis of the section of the productive strata of Azerbaijan’s fields, as well as identifies facies variability direction of the “pereryv” formation. Methodological aspects of studying the structure of grains of deposits of the productive strata using a binocular microscope are considered. A 3D model of the spatial arrangement of the facies of the alluvial-delta genesis was constructed and their relationship with the structure of the South Caspian Depression was established, which makes it possible to correctly design wells both during prospecting and exploration drilling, and during field development.
