Abstract The formation of the deep oil and gas bearing horizons hydrogeological conditions in the Middle Ob region and the West Siberian megabasin as a whole contains many questions and is a subject of discussion. This is due to numerous hydrogeodynamic and hydrogeochemical anomalies that do not have an unambiguous explanation. The hydrogeological conditions feature of the area under consideration is inversion hydrogeochemical zonation in the Lower Cretaceous and Upper Jurassic sediments, as well as the presence of low-mineralized formation waters of hydrocarbonate-sodium composition. The change in the genetic type of waters, the mineralization decrease, the calcium ion content decrease and an increase in the hydrocarbonate ion amount in the Mesozoic hydrogeological basin, is associated with the transformation of mineral and organic matter in sedimentary rocks during their immersion, occurring at the elision stage of the basin development.

Based on pyrolytic data (3 995 samples from 208 wells) organic matter types of Bazhenov Formation are identified in the central part of Western Siberian basin. Zones of kerogen types I, II, III and mixed I-II and II-III are mapped. Content of sulfur, paraffins, resins and asphaltenes, viscosity, density, temperature and gas content in oils from Upper Jurassic and Lower Cretaceous sediments (3 806 oil pools) are mapped. Oil gradations are identified and distributed. The alternative model of zones of kerogen II and IIS types is presented. The established distributions of organic matter types can be used in basin modeling and in assessment of oil-and-gas bearing prospects.

According to the results of a comprehensive sedimentological study of the core and well log data, the dissection of the bat-upper Jurassic sediments of the South of the West Siberian oil and gas basin was carried out. Quasi-isochronous marked levels are identified. They are represented by transgressive surfaces, maximum flooding surfaces and extended carbonaceous layers. They are the basis of the performed correlation. A number of characteristic lithological-facies sequences diagnosed by well log data was established.

In the work, on the basis of the data of the analysis of theoretical works and the laboratory studies carried out, the prediction of the values of corrosion rates in the circulating systems of coke plants was carried out using the Langelier and Ryznar stability indixes. The laws governing changes in the thermal stability of water as a function of temperature and water quality indicators (pH, alkalinity, total salinity, calcium ion content) have been established. Analysis of the obtained data showed that there is a clear dependence of the scale-corrosion properties of water on temperature and its chemical composition. A stable and effective supplying water composition for the circulating water supply system of the Kharkiv Coke Plant has been established.

In the paper the material composition of volcanic-sedimentary Triassic and Permian-Triassic sediments of Severo-Sosvinsky and Sherkalinsky grabens is considered. The scheme of distribution of Triassic and Permian-Triassic sediments of the western territory of Khanty-Mansiysk Autonomous Okrug - Ugra is presented. The sections of the wells, that have revealed the sediments, specific for grabenlike depressions, are described. The oil and gas content of volcanic-sedimentary sediments of Permian-Triassic age in the west of Khanty-Mansiysk Autonomous Okrug - Ugra was analyzed.
