Refinement of the Structure of the Pirallahi-south Area and the Prospects for Oil and Gas Potential of the Qala Suite

Despite the fact that the area is in a long-term development, its prospects are closely related to the refinement of the geological structure and the study of the section of productive deposits. The complex tectonic structure of the structures located in the northwest of the Absheron archipelago does not allow for an accurate determination of the boundaries of the distribution of deposits, including the Qala suite. For this article, new structural maps were compiled based on a comparison of numerous geological and geophysical profiles and well logs. The areas of distribution of sedimentary deposits of QaS have been clarified, and drilling of an appraisal (exploratory) well 1202 has been proposed in order to clarify the tectonic structure of the area.
