Key words: facies model, facies sequence, facies unconformity, clinoforms, lithologically sealed structural traps.

A conceptual facies model of sedimentary basin describing it as stacked facies sequences confined by facies unconformity was generated. A conceptual model of clinoform sedimentary basin was proposed that allowed prediction of, firstly, structural traps with lithologic seal associated with micro-clinorform structure of shelfal sand reservoirs, and, secondly, structural traps with lithologic seal associated with dissecting the Achimov sheet sand by mudstone member markers into bodies with no hydrodynamic communication. Examples of such targets mapped in one of the biggest fields of West Siberia are shown. References

The Samotlorskoye field is one of the biggest fields in Russia. Largest reserves are confined to AV_1-5 formation units which have been developed for 40 years. Detailed 3D static and dynamic models are required to evaluate and localize remaining reserves. New approaches to well logging data interpretation are suggested to meet modeling and reserves estimation objectives: analysis of lithological features and permeability prediction with honoring reservoir types; estimation of porosity by SP method with using deconvolution; saturation determination by electric logging and capillary model during change in formation water salinity; horizontal and directional well-bore logging data interpretation, comparison and consistency of petrophysical data with well production performance. Also, the paper presents how the technology of integrated automated interpretation of logging data is implemented.

In reconstructing the paleorelief in the sedimentary section one can come to erroneous conclusions and incorrect predictions of reservoir and seal bodies distribution without accounting for sharply varying degree of compaction of shale (in 3-4 times) and sand (only by 15-20%) sediments. The paper presents some methods and results of conversion of present-day thickness into uncompacted thickness (as of the time of sedimentation) by core and logs (SP log) based on the case study of the Verkhnetyumenskaya subsuite in the south-west of Western Siberia.

Based on results of drilling at Verkhnechonskoye field, a detailed sedimentological model of preobrazhensky horizon was created, where four member can be identified that were formed under different facial conditions of shallow marine basin. The results obtained provide an explanation for low production rates and oil recovery factor at the field. A method of paleomorphological reconstructions was proposed that will enable to better understand the architecture and oil- and gas-bearing prospects of the Vendian carbonate complex.

Experience of digital simulation models showed that a simple increase of the spatial detail is not the key to an adequate description of field development. A more productive way is to define sufficient spatial detail and increased physical meaningfulness of hydrodynamic models. This article shows how to implement this ideology as an example Samotlorskoye field, one of the largest in Western Siberia.

In the article the actual problem of well test interpretation on vertical wells with hydraulic fracturing in conditions of low piezoconductivity is solved (heavy oil and low permeable reservoirs), where radial regime was not reached during the well test. The presented approach allows increasing the accuracy of interpretation, to lower uncertainty, and also to reduce necessary time for well test than it is required at the classical way of interpretation.

The classification of oil deposits by the complexity of their development and classification of enhancing reservoirs recovery (by R.Kh. Muslimov) are given.

The considerable role of matrix solid material, and most importantly, of an active mineral phase, forming the paltry part of the entire rock, in oil displacement is shown. Some measures, the implementation of which would contribute to the effective development of fields with hard-to-recover oil reserves are recommended.

The heat exchange between the atmosphere and the earth surface has a significant effect on the temperature distribution in the soil. The conditions variation on the ground surface leads to change of thermal regime and permafrost soil thickness. The calculations taking into account the key factors of the temperature regime forming allows to predict the temperature distribution in the soil. Thereby it is getting possible to correctly regulate the thermal-physic situation in the soil by the measures of heat exchange variation on the earth surface.
