ANALYSIS OF 2D SEISMIC EXPLORATION WORKS PERFORMED IN THE GEOLOGICALLY COMPLEX STRUCTURES OF THE BAKU ARCHIPELAGO

The article focuses on the assessment of the geologically complex structures of Baku archipelago, mainly Sangachal-deniz, Duvanni-deniz, and Khara-Zira anticlines which are located in the northern part of Baku archipelago. These complex geological structures were influenced by tectonic activities, including faults and mud volcanoes which were revealed by conducted seismic exploration from the 1950s to the present. Seismic attribute analysis, specifically Sweetness and Variance attributes were applied and the results were analyzed in order to interpret these features. These attributes allowed us to characterize the lithofacial changes and to identify fault systems and chaotic seismic patterns caused by volcanic activities. The geological evaluation of the 2D seismic exploration works carried out in the Sangachal-deniz-Duvanni-deniz-Khara-Zira area was performed using "IHS Kingdom Suite" and "Petrel" software packages. The integration of 2D seismic data with well and core data provides valuable insights into the reservoir properties, highlighting the potential for hydrocarbon exploration in this geologically complex area. The study underscores the importance of continued seismic exploration to refine subsurface models and identify hydrocarbon reservoirs.
