In this paper, the study of the oil and gas potential of reservoirs belonging to the lower suits of PS (Gala and UG suits) in the eastern part of the Apsheron Peninsula was considered. The presence of non-anticlinal traps in the down part of the sections in Absheron peninsula was established. However, in the studied area, the oil and gas prospects in these suites have not yet been sufficiently studied by exploratory drilling. The integrated analysis of the lithofacies surveys and exploration data made it possible to determine the oil and gas prospects of reservoirs related to the lower part of PS such as Gala and UG. In addition, the reanalyzing of the old geophysical materials by considering the new log data and the depth maps of Gala and UG suits allows us to define the bottom and top boundaries of these suits for future explorations. The mostly perspective orientation on the lower suits borders of Bina – Hovsan trough , western and eastern buried parts of Gala – Turkan – Zira and Surakhany – Garackhur folding zones consisted of several local uplifts, have been considered as new zones of oil and gas exploration.
