ABSTRACT Background. The present study is aimed at integrating core and to refine the lithological framework, identify the main facies environments, and develop a conceptual sedimentological model, which is important for predicting the distribution of productive zones. Aim. Determination of the facies environments of the Zhetybay East field based on core studies. The study and interpretation of facies environments allow for a detailed characterization of the geological conditions of sedimentation, the parameters of the hydrodynamic regime, and the features of the paleoenvironment, which serve as a basis for stratigraphic correlation, paleogeographic reconstructions, and applied geological predictions. Materials and methods. The primary sources of information include historical data for each well in the field, results of laboratory studies (both standard and specialized) of core samples from three wells. Results. As a result of a comprehensive analysis of core materials, a facies interpretation of the Jurassic productive deposits of the Zhetybay East field was performed. The study identified the main facies environments of sedimentation and resulted in the development of a conceptual model of the field. Conclusion. A facies interpretation of the Jurassic deposits of the Zhetybay East field was carried out based on core analysis. The results obtained allow for refinement of the geological model and prediction of the distribution of productive horizons.
