The authors present the results of geological and geophysical works and well data analysis, which were obtained using methods of geological mapping, stratigraphic profiling, and geological analysis. The wells were drilled within the south-western part of the Yevlakh-Aghjabedinsky trough. The paper also contains an assessment of the region petroleum potential. The demonstrated results of studies of oil and gas occurrence in Mesozoic deposits in the south-western part of the Yevlakh-Aghjabedinsky trough aimed at identification of promising zones for further investigations and exploration on the basis of geological and geophysical data and structural features of the region. The south-western part of the Yevlakh-Aghjabedinsky trough is situated at the Kurinsky trough and the Lesser Caucasus boundary; and complicated geological architecture is typical of it. The authors were concentrated on Mesozoic deposits, where the Jurassic-Lower Cretaceous volcanogenic-terrigenous and Upper Cretaceous volcanogenic-carbonate rocks are of key importance. The Upper Cretaceous carbonate rocks reach a considerable thickness, which makes them favourable for hydrocarbon accumulation. Paleostructural changes at the Eocene end and Paleogene beginning caused formation of new uplifts and variation of sediments’ depth of occurrence, thus influenced the oil and gas potential of the region. South-western part of the trough is expected to contain hydrocarbon resources because of the conditions favourable for hydrocarbon trap formation, especially in Upper Cretaceous and Paleogene deposits. Assessment of geological structure and paleostructural changes is indicative of high prospectivity of the south-western part of the trough in terms of hydrocarbon exploration, which requires further in-depth seismic studies and drilling wells for more precise assessment of hydrocarbon potential and economic viability.
