The exploration of oil and gas fields, their development, and the assessment of reserve potential are considered among the main and necessary conditions for obtaining reliable information about the reservoir properties of rocks forming the geological section. The Kura depression, which has significant oil and gas potential, is characterized by a complex structural-tectonic structure and specific sedimentation conditions. This area has been comprehensively studied for a long time using various geological and geophysical research methods. Based on the conducted studies, analyses were performed according to different empirical regularities. Oil and gas production in these fields is carried out from various horizons of the Upper Cretaceous, Eocene, Productive Series, Aghchagil and Absheron deposits, which have been under long-term exploitation. The geological structure of these fields has been studied using numerous geophysical and well logging methods, with each field divided into separate blocks and still under development. At the same time, the necessity of applying petrophysical approaches for more accurate prediction of oil and gas content is emphasized.
