The article discusses the controversial issues of well log correlation of the Riphean, Vendian, Cambrian and Mesozoic sequences, which is prospects for oil and gas within the Aldan-Maya petroleum region. The author's version of the stratigraphic correlation is based on the interpretation of logging data, seismic surveys, core description, archival and published materials. The results obtained can be used for stratigraphic picks correction and structural maps plotting.

The article describes the recent distribution of temperatures of rocks in the roof of Tyumen and Malyshev suites for the whole territory of the West Siberian sedimentary basin. A map of temperature changes in the regional oil and gas bearing horizon U2 was built. The prognosis of the temperatures distribution in the roof of Malyshev suite on the understudied by deep drilling in Arctic areas is made. The analysis of placement of the deposits in the Bath with different phase state of the hydrocarbons is presented.

The surface of the folded base of the platforms is an important geological boundary separating rock complexes formed in different geodynamic settings and characterized by different physical properties, which largely determine the patterns of formation of minerals in them. Therefore, determining the depth of its occurrence and morphology is not only theoretical, but also practical. Despite many years of studying the foundation of the west of the Turan Platform, there is no unity among geologists and geophysicists in their ideas about its structure, depth of occurrence and surface structure. In this regard, the aim of the work is to build a structural map of the surface of the foundation of the west of the Turan plate, to identify the main tectonic structures and their morphology. The construction is based on a comprehensive analysis of drilling materials and geophysical data. When drawing up the structural map, all the currently available geological and geophysical material was used, including data from drilling, gravity and magnetic surveys, and seismic surveys of various modifications, which made it possible to perform fairly detailed and reliable constructions. The article provides a detailed description of the surface structure of the folded base of the west Turan platform. The obtained results can be used in solving the issues of oil and gas potential of the studied territory. The folded base of the western Turan plate is a heterogeneous and heterochronous formation, differentiated by the depth of occurrence, which allows for morphostructural zoning of its surface.

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.

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.
