“…Nevertheless, a number of works devoted to the oil-source rock correlation of the South-Eastern part of the basin proved that oil of accumulations of the studied area was generated in Bazhenov formation only (Kontorovich, 1997;Goncharov, 2002). Besides, organic-rich shales of the lower Toarcian Togur Bed can be proposed as possible source for petroleum accumulation of the studied area.…”

TX 75083-3836 U.S.A., fax 01-972-952-9435. AbstractDuring the work a 3D model of oil migration for Jurassic petroleum system in the area of interest was created. Modelling was based on the MPath software developed by the Permedia Group, Ottawa, Canada.An integrated approach to the evaluation was taken including analysis of geochemical dataset, and geological information. 3-D cube with grid resolution 500x500 m was constructed from the map horizons built on the base of interpretation of 2-D seismic realized within the studied territory during resent 20 years.In order to provide complex analysis of petroleum system a number of its elements were evaluated: distribution and quality of source rock, including its richness and maturation of source rock; thermal history of the basin; quality and distribution of reservoir rocks including analysis of capillary threshold pressures; paleostructural setting of the territory during migration history.According to the geochemical source rock and oil correlation, Bazhenov formation was considered as a principle source rock for the studied area.Expulsion modelling demonstrates that main kitchen areas are confined to depressions located in the eastern and north-eastern part of the territory -Yuzhno-Koltogor depression and Ilyahskiy Flexure. The main migration scenario suggests that that oil migrated stratigraphically downwards from Bazhenov source rock, then lateral migration in fill-spill manner occurred in the Upper Vasyugan J 1 carrier beds.Model obtained shows good predictive power in reconstruction of secondary migration processes and demonstrates rather good correlation with real data. Moreover, model obtained allows proposing increase in STOOIP for several low studied "small" fields located within the area.

“…The migration and thickening of heavy oil in the West Siberia Basin occurred during a period of active Turonian-Pleistocene tectonism. The Lower Cretaceous heavy-oil reservoir was at a shallower depth than now (Kontorovich, 1997). Moreover, faults in the sedimentary cover played an important role in hydrocarbon migration, degradation and accumulation.…”

Gl obal recoverable resources of heavy oil and oil sands have been assessed by CNPC using a geology-based assessment method combined with the traditional volumetric method, spatial interpolation method, parametric-probability method etc. The most favourable areas for exploration have been selected in accordance with a comprehensive scoring system. The results show: (1) For geological resources, CNPC estimate 991.18 billion tonnes of heavy oil and 501.26 billion tonnes of oil sands globally, of which technically recoverable resources of heavy oil and oil sands comprise 126.74 billion tonnes and 64.13 billion tonnes respectively. More than 80% of the resources occur within Tertiary and Cretaceous reservoirs distributed across 69 heavy-oil basins and 32 oil-sands basins. 99% of recoverable resources of heavy oil and oil sands occur within foreland basins, passive continental-margin basins and cratonic basins. (2) Since residual hydrocarbon resources remain following large-scale hydrocarbon migration and destruction, heavy oil and oil sands are characterized most commonly by late hydrocarbon accumulation, the same basin types and source-reservoir conditions as for conventional hydrocarbon resources, shallow burial depth and stratabound reservoirs. (3) Three accumulation models are recognised, depending on basin type: degradation along slope; destruction by uplift; and migration along faults. (4) In addition to mature exploration regions such as Canada and Venezuela, the Volga-Ural Basin and the Pre-Caspian Basin are less well-explored and have good potential for oil-sand discoveries, and it is predicted that the Middle East will be an important region for heavy-oil development.

Wettability of organic-rich source rocks: case study on Bazhenov Formation (Abalak-Bazhenov group)

Abstract. In this work, we have investigated the wettability of Bazhenov Formation rock samples using a nuclear magnetic resonance (NMR), the methods of vapor adsorption, and wetting contact angle. We have conducted the petrographic description of rocks using ultra-thin sections and scanning electron microscopy (SEM). In addition, we used data on the organic content (TOC) obtained by the Rock-Eval method and the results of lithological typing on thin sections for detailed analysis of NMR and contact angle methods results. Thus, for target rock, the groups with a similar rock wettability were highlighted by the lithological description of thin sections. The calculation of the wetting angle provided an initial assessment of the surface wettability of the rock and made it possible to establish the relationship between the wetting angle and the TOC, which is relevant for rocks of the Abalak-Bazhenov group. The NMR method described the core plug wettability proved to be less sensitive to the rock lithotype and organic matter (OM) texture in the rock and, therefore, used for the integral characterization of core plugs. Correlations of calculated wetting angle and adsorption wettability index vs. TOC and OM texture illustrated the dependence of rock wettability behavior on both the lithological specifics and the OM properties.
