The role of the "land-sea" transition zone in the formation of oil and gas deposits in the Azerbaijani sector of the southern caspian

Abstract

Analysis of drilling data suggests that the activity of the buried volcano began at the end of the Middle Pliocene or the beginning of the Upper Pliocene and ended in the Middle Absheron. The activity of the Khara-Zira mud volcano most likely started at the end of the Productive Layer era and is currently ongoing. The Bulla-Sea uplift is an enclosed fold structure. Based on the VII horizon of the Productive Layer in the Garadag region, the Bulla-Sea uplift is primarily a large brachyanticlinal fold that is symmetric in the transverse section and asymmetric in the longitudinal section.
