The Pre-Caspian Basin is a palaeo-depression located in the western part of Kazakhstan and Russia, bounded by the Palaeozoic carbonate platform of the Volga-Ural province to the north and west, and by Hercynian fold belts to the east and south. The basin hosts one of the largest hydrocarbon reserves in central Asia, principally within the excellent reservoirs of the Upper Devonian - Lower Permian carbonate platforms on the basin margins. The aim of this study is to understand the evolution of a carbonate platform in the northern portion of the Pre-Caspian Basin with particular attention on the processes of karstification. The controls on karst development are addressed through a sequence stratigraphic approach, in order to construct a geological and geometrical model of the evolution of the karst geometries. The 3D seismic data available allows the implementation of a multi-attribute approach in characterising structures and morphologies of interest. The results of this study have a positive impact on the understanding and reduction of the uncertainty associated with behaviours of fluid flow within karst-related structures.
