This study examines the methods of analysis and interpretation of geological and geophysical data aimed at identifying and describing clinoform structures and their properties in the Ustyurt region. The work utilizes 3D seismic survey data, geophysical well studies, and the results of seismic facies analysis and PMLI inversion to assess the porosity and gas saturation of the formations. The objective of this work is to study the clinoform structure of Paleogene gas deposits in the Ustyurt region and to identify the geological patterns governing the formation of productive horizons within clinoform structures. This aims to improve prediction accuracy and the efficiency of oil and gas field development. The focus is on analyzing attribute maps such as Signal Envelope, Vp/Vs, and Fluid Factor, which have allowed for the identification of zones with improved reservoir properties and the determination of promising drilling sites. These maps have shown a high degree of correlation with GIS data, enhancing the reliability of forecasts and optimizing field development processes. The study demonstrates that a comprehensive approach, including seismic facies analysis and PMLI inversion, is an effective tool for identifying productive horizons and zones with high reservoir properties. The results obtained provide opportunities for improving the accuracy of geological predictions and increasing the efficiency of gas extraction in the region. Future research is expected to further refine existing models and develop new methods for hydrocarbon exploration and extraction in challenging geological environments.
