In the geological section of Perm Region Upper Proterozoic sediments lying below the industrial development of the oil industry depths are considered as potentially oil generating and oil productive column. As part of these deposits two sets of rocks were allocated: Riphean and Vendian, degree of scrutiny that is uneven. This study was conducted on the results of the processing sections 700 wells penetrated these deposits in the Perm region. According to a survey set spatial boundaries spread stratigraphic subdivisions of the Riphean and Vendian complexes, changing the thickness and lithology Analyzed geological and geochemical information allowed to identify in these deposits Kaltasinsky retinue Lower Riphean complex having the most optimal and favorable conditions during sedimentation in terms of forming generation potential. To assess the possibility of generation of petroleum hydrocarbons in sediments authors analyzed Kaltasinsky Formation geological, chemical and pyrolytic bituminous indicators (from 200 - to 400 determinations). Using statistical analysis methods parameter distributions studied by area spread Kaltasinsky suites and the section in the Perm region. Zoning development of Kaltasinsky Formation was carried out by the degree of intensity of oil and gas generation. Thus, the analysis made it possible to differentiate the study area on the prospects of a possible oil and gas potential on the basis of the study of geological and geochemical characteristics of the organic matter of rocks and highlight priority areas for more detailed studies of the structural, tectonic and other features that characterize the conditions of migration and accumulation of hydrocarbons in the Upper ancient sediments.

The main purpose of this paper is to study the processes of formation of oil and gas potential in the Ural thrusts by the example of the Arakaevskaya key 1 well area located in the Sverdlovsk region in the poorly studied Lower-Serginsky perspective oil and gas area of West-Ural folding zone. According to the results of a comprehensive study of core and geophysical investigations have revealed a complex structure of the well section, divided into three parts (autochthon, parautochthon and allochthon), no oil shows and the development of the gas in the allochthon. Throughout the studied sections revealed widespread bitumen, as oil degradation products, and at the bottom of parautochthonous presence destroyed oil deposit, which occur in the generation of the Upper Devonian source rocks. According to the results of 1D basin modeling using palinspastic reconstruction concluded that the identified gas content in the Lower-Middle Carboniferous allochthonous rocks caused by the generation of gases in the source rocks after development processes of thrust dislocations and possibly at the expense of the destruction of the oil deposit. Due to the fact that Arakaevskaya well is drilled in the frontal part of thrust we suggested the possibility of oil deposits conservation in other areas of the Lower-Serginsky perspective oil and gas area. The results can be used to assess the petroleum and gas potential of the zone of folding of the Sverdlovsk region and other regions. Source

On the statistical level influence of different parameters on the petroleum geology of complicated structures in the Devonian clastic sediments in the Udmurt Republic is considered. Individual and complex probabilistic and statistical forecast model of oil and gas occurrence is constructed. The evaluation of oil and gas produced and identified local structures is carried out.
