MODELING OF FRACTURING IN A CARBONATE RESERVOIR: A CASE STUDY OF THE "VOSTOK" FIELD

Abstract

The article presents the results of modeling the fracturing of a carbonate reservoir within the Carboniferous deposits of KT-I and KT-II horizons, using an example from a field in the Eastern Flank Zone of the Pre-Caspian Depression. The structural features of the object are described in detail, including the presence of faults and a developed fracture network, which affect its filtration-capacity properties.

Modern geological modeling methods adapted for carbonate and fractured reservoirs were applied in the study. The result of the work was the creation of a three-dimensional geological model reflecting the distribution of high-fracture zones and their connection to well productivity.

The obtained model allows for the assessment of the impact of structural heterogeneities on the reservoir properties, significantly enhancing the accuracy of well productivity forecasting and optimizing subsequent development planning.
