The depletion of reserves at mature hydrocarbon fields in Kazakhstan necessitates the development of new approaches for regional petroleum prospectivity assessment. The South Torgay sedimentary basin remains one of the most promising hydrocarbon provinces of the Republic of Kazakhstan, hosting several large and medium-sized oil and gas fields. However, despite its recognized petroleum potential, significant parts of the basin remain insufficiently studied, particularly with respect to the spatial relationships bet...

The Akshabulak and Aryskum structures, located within the Aryskum depression of the South Torgay sedimentary basin, are among the most thoroughly investigated hydrocarbon-bearing areas in Kazakhstan. The discovery of several oil and gas fields in these structures was facilitated by seismic surveys conducted between 1986 and 1988. The present study aims to develop predictive exploration models based on the analysis of density heterogeneities and the distribution of horizontal lithostatic pressure components derived...
