pdf Heat flow and thermal history of the Togur formation (Lower Jurassic) sources rocks and data about petroleum bearing East-Paidugin megadepression (south-east of Western Siberia)
The poorly studied East-Paidugin megadepression and the structures of its framing in the south-east of Western Siberia are new territories and new stratigraphic levels that are promising for predictive prospecting studies on the Lower Jurassic and pre-Jurassic petroleum bearing strata.
Paleotemperature modeling was performed in cross section of 26 deep wells. It is established that the value of the heat flow density varies within 36-56 mW/m2. The modeling is based on solving the heat conduction equation of a horizontally layered solid with a moving upper boundary, using original computer technology.
Schematic maps of the deep heat flow density on the Paleozoic basement top were constructed for the research area, and mapping of the catagenetic generation foci of the Togur oil was carried out.
Express-evaluation of the oil generation density identified potentially productive zones for oil accumulations searching in the Lower Jurassic and Pre-Jurassic sections. These productive zones represent the entire East-Paidugin megadepression, including the Vargat mezodepression, as well as the western part of the Vladimir megaledge (the western slope of the Belonogov mezoval) and the eastern part of the Parabel megaledge (the northeastern slope of the Kolpashev mezoswell).

Keywords: Togur Formation source rocks, paleotemperature modeling of the oil generation sources, oil generation density, potentially productive zones of the Lower Jurassic and pre-Jurassic petroleum bearing strata, East-Paidugin megadepression, south-east of Western Siberia.

pdf Heat flow, Triassic rift system and Mesozoic-Cenozoic faults (south-east of Western Siberia)
A qualitative and quantitative assessment of the influence of the Triassic rift system and Mesozoic-Cenozoic faults on the modern thermal field in the west of the Tomsk region has been carried out. It was revealed that the rift structures of the basement are not reflected in the modern thermal field, as well as disjunctive disturbances of the sedimentary cover, which is explained by the ancient age of their formation.

Keywords: thermal field, basement rift structures, disjunctive disturbances, Tomsk region.

pdf Hydrocarbons generation focis and accumulation within the pre-Jurassic section of the deep drilling Selveikin area (Tomsk Region)
Concurrent modelling of catagenetic focis of hydrocarbon generation in sedimentary basins: “present” Jurassic-Cretaceous and Silurian, Lower-Middle Devonian, Upper Devonian-Lower Carboniferous “paleobasins”, was performed for the first time. It was stated that the source rock of gas in reservoirs of the weathering crust and top of inner Paleozoic in conditions of geological and geophysical cross-sections of Selveikin area most likely is “Devonian” – domanicoid rocks of Chagin Formation.

Keywords: modelling of catagenetic foci of hydrocarbon generation, “present” sedimentary basin and Paleozoic “paleobasins”, reservoir of the weathering crust and inner Paleozoic, Tomsk Region.

pdf  Zoning of the shale oil area belonging to the southern part of the Koltogor-Urengoy paleorift
The search for “shale oil" remains an urgent task for Western Siberia, where the Upper Jurassic Bazhenov Formation is widespread. The developed infrastructure of the southeast area defines these lands as priority for zoning and allocation of prime areas. In tectonic terms, the studies are confined to the Koltogor-Urengoy paleorift and its framing structures. According to the geothermal criteria, the centers of generation and accumulation of Bazhenov oil have been identified in situ. The integral indicator of the density of generated oil resources is calculated, taking into account the time of the main oil generation zone and the geothermal temperature in this zone. Areas with high prospects of prospecting for "shale oil" are distinguished.

Keywords: shale oil, Bazhenov Formation, paleotemperature modeling, oil resources density, Koltogor-Urengoy paleorift, Western Siberia.

pdf Zonation of megadepressions of the Tomsk region depending on the frequentness of shale oil resources
It is assumed that main volume of shale oil (accumulated in situ) are localized where source rocks were in the main zone of oil generation ('oil window'). The results of zonation of Bazhenov Formation of Nyurolsk and Ust-Tymsk megadepressions by frequentness of shale oil resources performed at first time are presented. Zonation is based on the method of paleotemperature modeling, which allows to reveal and map areas of intensive oil generation in the source rocks by geotemperature criteria.

Keywords: shale oil, the Bazhenov Formation, main zone of oil generation, paleotemperature modeling, resources frequentness, Nyurolsk and Ust-Tymsk megadepressions.

pdf  Assessment of the influence of permafrost strata of late quaternary climate cooling on the geothermal regime of oil-sorce deposits of Western Siberia

The probable paleoclimatic factors influencing the formation of the geothermal regime of oil source deposits are determined: 1) secular variation of temperature on the surface of the Earth; 2) the formation and degradation of neopleistocene strata of permafrost rocks; 3) Late Quaternary ice caps. The purpose of research is quantitative assessment of the impact of frost on the geothermal regime and the implementation of the generation potential of Bazhenov sediments in the southeast of Western Siberia (latitude of Tomsk region). The author's method of research based on the method of paleotemperature modeling is applied - solving the inverse and direct issues of geothermy under a sedimentation conditions. It was established that the account of permafrost with thickness of about 300 m is required for adequate recovery of the thermal history of oil source deposits on south-eastern areas of Western Siberia. This will enable to properly take into account the history of the main phase of oil generation and not to underestimate (up to 25%) the hydrocarbon resources.

Keywords: geothermal regime of Bazhenov sediments, neopleistocene permafrost, paleotemperature modeling, hydrocarbon resources, south-east of Western Siberia.

pdf  Influence of paleoclimate on geothermal particularity and on the oil-generation potential of the Bazhenov Formation (south-east Western Siberia - Novosibirsk region)
The review of researches about the influence of paleoclimate (a century level temperatures chart on the surface of the Earth) on thermal history of deep source rocks and its influance of its generation potential is provided. Influence of the Mesozoic-Cenozoic climate on a geothermal regime of the Bazhenov Formation source rocks of south-east Western Siberia (Novosibirsk region) is estimated. The paleoclimate assessment on the basis of paleotemperature modeling verification results and identification by geotemperature criterion of paleospot of the Bazhenov oil generation in sedimentary sections of three deep wells which have been drilled in Bazhenov Formation on the Verkh-Tarsk area is carried out. The reconstruction of the thermal history of source rocks excluding paleoclimate won't be coordinated with "maximum paleotermometry" - vitrinite reflectance data and construct petroleum potential section. The local century course is recommended to be considered when determining of hydrocarbon resources by a volume and genetic method of the Tomsk, Novosibirsk and Omsk areas. Local century level temperatures chart of Earth's temperatures of the terrestrial surface, used at construction and reconstruction for the Southern Siberian paleoclimate zone, significantly contribute to ameliorate the oil resources prognose.

Keywords: paleoclimate, paleotemperature modeling, source rock, Bazhenov Formation, inferred resources, South-East of Western Siberia.

pdf  Reconstruction of geothermal history of the petroleum bearing Bazhenov Formation and estimation of the distribution of the offshore Neocomian reservoirs of the Nyurol megadepression
Description of the Neocomian shelf strata of the Nyurol megadepression and their structure is presented. Termal history of the Bazhenov source rocks strata is evaluated using the method of paleotemperatures modeling during the Jurassic time. Paleo-centers of oil generation are revealed and mapped considering geothermal criteria. Built maps of resources generation concentration and primary accumulated Bazhenov oil in the shelf reservoirs are presented. Recommended priority exploration areas are revealed.

Keywords: Neocom shelf, Bazhenov Formation, paleotemperature modeling, oil generation levels, density resources, Nyurol megadepression.
