Abstract: The paper discusses the conditions of formation and development of reservoir properties (porosity and permeability) at great depths of the Earth’s crust. Using geomechanical modeling technology, secondary permeability of deep Paleozoic deposits of the southern part of the Ural foredeep was estimated. The carried out research allowed to reveal the areas of increased fracture values. These zones are the most favorable for hydrocarbon accumulations search in the southern part of the Ural foredeep
