In the southern regions of Russia met with changes in the composition and properties of rocks and formation waters in the exploration of gas fields in the result of the formation of gas hydrates in the upper layers of the lithosphere. Production and there is the need to develop scientific methods for predicting the extent and direction of the composition and properties of rocks and formation water at hydrate processes in the Caspian Kalmykia (Kalmyk sector in South-West region of the Caspian basin) during the construction and operation of geological-¬ of facilities to minimize the impact on the cryogenic natural and industrial systems. During the development of hydrocarbon resources in the Caspian Kalmyk man-made cryogenic processes occur in rocks of estuarine zones around the wells and pipeline of commercial communications. Frequency of cryogenic freezing of rocks deep below the natural freezing, alternating with cyclic defrost them in the summer, changes the physical and mechanical properties of the rocks in which an industrial-technical systems, thereby reducing the load-bearing capacity of rocks, their density and coupling with industrial sites and objects, broken system mounting of industrial facilities and pipelines, leading to a crash and man-made disasters.
