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.

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.

It is shown that the evolutionary-catagenetic model for calculating the initial potential hydrocarbon resources can serve as a scientific basis for the separate quantitative prediction of areas of oil-and-gas content. In this case retrospectively evaluated are the scales of generation and accumulation of hydrocarbons in the source rocks during catagenetic evolution of sedimentary basin. The authors propose a method, the results of evaluation of generation and accumulation scales and initial potential oil and gas resources for major oil-and-gas bearing complexes of Dzhebol stage.

In this paper, four general directions are described to make evaluations and their resource potential; those are coal structure and coal level, gas content of deep coalbed, the coalbed thickness and distribution and the buried depth of coalbed. Coalfields of the study area are mainly Permian and Carboniferous coal seam of Shanxi Formation coal and Benxi group 11 # coal, coal seam depth 1370-1812m. No. 3 coal-seam average layer thickness of 1.6 m, the monolayer most 2 m thick; No. 11 coal-seam in the average layer thickness of 3 m, single-layer thickness of 4.5 m. Predict the amount of coal resources of 17.3 one hundred million t. Predict coal-bed methane resources of 27.68 billion cubic reserve abundance of 104 million square / km2 in. The exploration results show that this region has good development prospects.

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.
