“…Short brachyanticlinal form, complication of the structure by numerous faults suggest high rates of the development and -unlike the other folds -much more active development regime. We should note that those fea-tures were neither specific to other folds we studied nor the structures of the anticlinal zone of the Goshadash-Darwin kypesi Pirallahi adasi-Janub, which conentionally includes the Janub structure (Mukhtarova and Nasibova, 2020).…”

In the article, based on the study of paleotectonic, paleotemperature properties of the evolution of the western and eastern semi-basins of the South Caspian depression (SCD) and of the local elevations that have developed there, we found that within the Absheron Ridge and Turkmen shelf, which make up the north-northeastern slope of the depression, compressive stresses played a key role in the formation of local elevations, development of faults and mud volcanism, and in their oil and gas potential. By using a number of paleoprofiles constructed based on the seismogeological profile running in a southwest-northeast direc- tion, as well as morphological specifics of the local elevations developed within both the Absheron Ridge and the Turkmen shelf, we plotted and analyzed isomorphic maps reflecting the properties of distribution of the compressive stresses. Based on the paleoanalysis, we determined that the isometric Janub elevation, neither morphologically nor genetically, can be included into the same anticline zone as the local elevations under consideration. Studies suggest that they have developed under different tectonic regimes and the Janub structure belongs to a group of folds formed under another tectonic regime, i.e. new predicted anticline zone. The Janub-2 elevation, located southeast of the Janub fold, can be attributed to the predicted new anticlinal zone. In order to trace the continuation of this anticline zone in the southeast direction and identify potentially promising new buried elevations, it is advisable to carry out new series of transverse deep seismic profiling works in the southwest-northeast direction. The analysis revealed that the oil and gas potential, folding and evolution of mud volcanism in the area under study are associated with geodynamic processes. The impact of compressive stresses, as a geodynamic factor, on folding and faulting of the sedimentary mantle, mud volcanism and oil and gas potential is a relevant topic to study. The main research objective was determining the directions of exploration works based on deeep structure, paleotectonic, geodynamic and paleotemperature evolution environment of the SCD.

“…The Mishovdag fold is located on the Kalamaddin-Bandovan anticline zone between the Kichik Harami (in the northeast) and Galmaz (in the north-west) structures (Ganbarova, 2022;Mukhtarova, Nasibova, 2020). The fold is represented by a brachianticline, 20-25 km long and 4-6 km wide.…”

The article analyzes the geological structure, lithofascial, tectonic, and morpho- logical features of the Mishovdag oil field, which is a productive area in terms of oil content. Morphologically, it represents a brachianticlinal fold located in the north-west and south-east directions. The Mishovdag fold is located on the Kalamaddin-Bandovan anticline zone between the Kichik Harami (in the northeast) and Galmaz (in the northwest) structures. The Mishovdag-Galmaz part of the anticlinal zone extends in the sub-southern direction. The structures included in the zone are represented on the surface mainly by Aghjagil, Absheron, and ancient Khazar sediments. Productive layer sediments come to the surface in few areas. The tectonic movements and activity of mud volcanoes (active or buried) have left characteristic traces in the geological structure of the research area. Brachianticlinal and other types of structures were formed here. Under the strong influence of tectonic movements, the layers forming them were deformed and broken into blocks by regional tectonic faults. The anticlinal structures of the zone are complicated by longitudinal and latitudinal faults. The Mishovdag fold is represented by a brachianticline, 20-25 km long and 4-6 km wide. Brachianticline has a sharply asymmet- rical structure. The southwestern limb is steep, and inclined at an angle of 25-450, while the northeastern limb is flat and characterized by an inclination angle of 7-250. As a result of the analysis of the cross-sections of deep wells drilled in the field, it was determined that Mesozoic, Paleogene-Miocene, and Pliocene-Anthropogenic sediments are developed in the section of the fold. Sediments repre- senting the cross-section are characterized by high reservoir properties. Geological-geophysical works are carried out in the field. Core materials were taken from wells. The lithological-petrophysical characteristics – carbonate, porosity, and permeability of reservoir rocks have been determined according to core samples taken from exploration wells drilled in the field. The lithological-petrophysical characteristic regularities of change were investigated depending on depth.
