Paleohydrodynamic factor of the formation of the hydrocarbon deposits of the north-western part of the outer zone of the Pre-Carpathian foredeep

Paleohydrodynamic schemes of the Badenian-Sarmatian deposits of the north-western part of the Outer zone of the Pre-Carpathian foredeep are built on the basis of paleohydrodynamic reconstruction of paleopressures of formation waters of elision stage of sedimentary basin. Results of paleohydrodynamic reconstructions have demonstrated that the most part of the explored gas fields of the region is localized in the limits of the marked areas of inherited pressure minima. Comparison paleo- and modern hydrodynamic situation enable us to draw conclusion about conditions of field formation.
