Geological assessment of Gurgan-Deniz field based on seismic attribute analysis

The seismic analysis of the hydrocarbon-rich Gurgan-Deniz Field in the expansive Caspian region is vital for efficient exploration and maximizing resource potential. This comprehensive study leverages sophisticated seismic techniques to unravel the basin’s intricate subsurface architecture and stratigraphic layering, characterized by geological complexities. The area’s diverse tectonic history and varied depositional settings pose unique interpretive challenges and exploratory opportunities. By integrating high-resolution seismic data with geological computer modeling, this investigation aims to enhance the comprehension of these intricacies, thereby supporting optimized exploration strategies. The paper outlines the seismic data acquisition, processing, and interpretation methodologies employed, providing a detailed analysis of the structural and stratigraphic features revealed. Such insights are crucial for petroleum prospecting and reserve estimation efforts within the enigmatic Gurgan-Deniz Field. Utilizing 3D seismic data and attribute analysis, the study examines dynamic parameters of seismic waves and lithological properties of rocks, with a focus on RMS Amplitude, Relative Acoustic Impedance (RAI), and Chaos attributes. The integration of seismic attribute analysis with well and core data allows for accurate predictions of reservoir properties and the spatial distribution of potential hydrocarbon-bearing formations. This approach not only delineates prospective areas but also mitigates exploration risks and optimizes resource development in this strategically significant region. The findings demonstrate the effectiveness of seismic attribute analysis in navigating complex geological environments, providing valuable guidance for future exploration and development activities in the Absheron Archipelago. Overall, this study contributes to optimizing resource extraction and management strategies, underscoring the critical role of advanced geophysical techniques in hydrocarbon exploration and emphasizing the potential of these methods to enhance the efficiency and accuracy of exploration efforts in challenging geological settings.
