|Lithological features and filtration potential capacity of subsalt Vendian complex rocks of Eastern Siberia|
|On the basis of huge amount of factual data the lithologic and petrophysical characteristics of productive deposits of the Vendian complex of south of the Siberian platform are analyzed. The schematic maps of distribution of open porosity and permeability of carbonate and clastic rocks are constructed and analyzed for individual layers and areas of improved reservoirs are distinguished. The proposed maps show differences between petrophysical features of rocks that form the hydrocarbon bearing strata, as well as their variation within the major structures of the studied region. The promising areas for hydrocarbon deposits prospecting are highlighted taking into account the reservoir properties data for the studied area.
Keywords: Vendian, clastic sediments, carbonate sediments, porosity, permeability, fracture, reservoir, productive deposits, Baykit anteclise, Katanga saddle, Nepa-Botuoba anteclise, Siberian platform.

|Hydrocarbon concentration zones of land and offshore areasin the oil and gas basins of the East European platform margins(Barents-Caspian oil belt)|
Timan-Pechora, Volga-Urals and Caspian oil and gas provinces are located at the East European Platform margins as well as north and south adjacent Barents-Kara and North Caspian oil and gas provinces. Barents and Caspian oil and gas bearing zone is one of the richest oil and gas bearing zones in the world. The study of geodynamics, paleogeography, non-anticline traps distribution, zones of reservoir pinching-out at the East European Platform margins has allowed us to draw conclusions on hydrocarbon concentration zones of land and offshore areas of the oil and gas basins of Barents and Caspian oil and gas bearing zone.
Key words: Barents and Caspian oil and gas bearing zone, geodynamics, paleogeography, non-anticline traps, thinning zones.

|Ways of paleomagnetic records researchfor petroleum geology problems solution (Timan-Pechora province)|
|Some of new or only occasionally used ways of paleomagnetic records research in the sediment deposits are being discussed in order to solve the petroleum geology problems related to the study of paleogeodynamic and paleogeographic development environments of sedimentary basins as well as the processes of transformation constituent rocks. Experience in assessing of possible influence of geodynamic factors on the formation of sedimentary rocks, petroleum potential and migration ways of hydrocarbons of different tectonic cycles in the Timan-Pechora province is being discussed as an example. Analysis of the basin geodynamic development can identify generation areas, set the ways of hydrocarbons migration in reservoir strata, because gas fields form in areas of most subsidence, while oil fields form in areas less subsident. In conclusion, a summary of principles for solution of the geodynamics problems based on the study of paleomagnetism phenomena is given and several examples for problem solution in the area of hydrocarbons migration and accumulation on this basis in other regions are mentioned.
Key words: paleomagnetic research, geomagnetic field, geodynamic models, paleomagnetism, stratigraphy, oil and gas basins stratigraphy.

|Nonanticlinal traps - examples from Volga-Ural and Western Siberia oil-and-gas provinces|
|In the conditions of considerable output of hydrocarbon deposits in anticlinal structures in majority of oil and gas provinces of Russia, the main perspectives of hydrocarbon production is associated with non-anticlinal traps. Non-anticlinal traps are divided into four types: lithologically restricted, lithologically screened, stratigraphically screened and tectonically screened. These types are divided into subtypes and classes. Examples of traps of different types in the Volga-Ural and Western Siberia provinces are presented.
Key words: non-anticlinal trap, the Volga-Ural province, the Western Siberia province.
