Purpose. The development of a methodology for interpreting geophysical data for complex terrigenous reservoirs based on multidimensional interpretation relationships and consideration of thin layers to improve the accuracy of evaluating reservoir filtration-capacity properties and saturation. Methodology. A comprehensive research approach was employed, which included: generalization of petrophysical characteristics of formations based on well logging data (WLD); their analysis using multidimensional interpretation models; investigation of filtration-capacity properties (FCP) in thin reservoirs; and the construction of graphical and statistical models for visualizing the obtained results. Findings. A methodology for evaluating filtration-capacity properties based on petrophysical and interpretation models of WLD has been developed. This methodology is designed for analyzing complex terrigenous reservoirs, including thin formations (up to 2 meters), and enhances the accuracy of their interpretation. The effectiveness of the software was confirmed through the analysis of such reservoirs, ensuring higher calculation precision and accelerating the decision-making process. New interpretation approaches have been developed, taking into account formation structure patterns and the distribution of their filtration-capacity properties and saturation. A comparison with production data validated the methodology, improving the accuracy and efficiency of geophysical studies of oil and gas-bearing sequences. Originality. For the first time, a methodology for evaluating filtration-capacity properties has been proposed based on the application of multidimensional interpretation relationships in petrophysical and interpretation models, which has enabled data integration and adaptation for studying various types of terrigenous rocks. This, in turn, has expanded the possibilities for analyzing complex reservoirs and improved the accuracy of assessing their filtration-capacity properties and saturation. For the first time, patterns in the structure of terrigenous reservoirs have been identified, and the distribution characteristics of their filtration-capacity parameters and saturation have been quantitatively justified. Practical value. The application of multidimensional interpretation relationships in the developed methodology has significantly enhanced the reliability and efficiency of geophysical analysis of oil and gas-bearing sequences. The formation of models within a unified methodological approach has systematized the study process of complex reservoirs, allowing for the standardization of their investigation methods at various stages of well analysis. The use of the developed models enables a more precise assessment of reservoir oil and gas saturation, helping to minimize risks in production planning and increase hydrocarbon recovery rates. The proposed methodology can be implemented in geophysical studies of fields with various types of terrigenous rocks, making it a universal and valuable tool for a wide range of tasks in the oil and gas industry.
