Ether-geosoliton model of geological processes, developing V. I. Vernadsky's ideas (the degassing of the Earth) and D. I. Mendeleev’s ideas (mineral petroleum origin), explains not only the formation of hydrocar-bons and the formation of oil and gas fields, but also offers new approaches to the search and exploration of strategic raw materials in hydrocarbon fields in Western Siberia.

From the viewpoint of seismic survey, transition zone is a shallow water area where it is impossible to use marine cables because of low depth, there are difficulties in terms of coordination between geophones and environment, usage of explosives is prohibited, usage of air guns is ineffective. And besides, there are in-creased requirements concerning ecological safety. In order to solve this problem it is necessary to use multiva-riant systems of emergence, reception and registration, that is complex usage of explosions, surface sources, air guns, bottom and surface geophones and hydrophones. It is necessary to use overlapping and special technolo-gy for combination of data received from different systems and different field seasons (summer, winter).

The article describes the recent distribution of temperatures of rocks in the roof of Tyumen and Malyshev suites for the whole territory of the West Siberian sedimentary basin. A map of temperature changes in the regional oil and gas bearing horizon U2 was built. The prognosis of the temperatures distribution in the roof of Malyshev suite on the understudied by deep drilling in Arctic areas is made. The analysis of placement of the deposits in the Bath with different phase state of the hydrocarbons is presented.

The article considers the wells that have penetrated the carbonate sediments with the geological and paleontological information. By the late Devonian epoch paleogeographic scheme they are located in certain megazones with their inherent characteristics of sedimentation. Examples of lateral relations of carbonate or shalecarbonate rocks with subordinate volcanic rocks on Lovinsky and Khanty-Mansi areas are given. A variety of types of carbonate rocks is associated with structural features of basins in which there was sedimentation, as well as various secondary processes. Based on new geological information, obtained in recent years on Galyanovsk, South Galyanovsk, Khanty-Mansi and other areas, the areas of distribution of carbonate deposits within the Frolovskaya megadepression are clarified. Their petroleum potential is associated with reef structures is mostly confined to near rim parts of the deep depressions of the basement, a reliable mapping of which is possible with more detailed geophysical work.

It has been almost fifty years that the so called Bazhenov suite anomalous sections, i.e. formations distinguished by sandy-aleuritic inclusions in Bazhenov bituminous clay attract the wide range of geologists and geophysicists who circulate innumerable, often exotic assumptions concerning generation of anomalous sections. Integrated analysis of mixed geological and geophysical data on anomalous sections formation proved that the initial definition of the former as submarine landslide dislocation by K. I. Mikulenko and G. B. Ostry remains most accurate.

Rift trough of Central Africa have been studied in detail since the early 1980s and during this time, signifi-cant hydrocarbon reserves were discovered within these structures. The most promising is the Mujlad basin, within which the thickness of the sedimentary cover can reach 13,5 km. Analysis of the core material made it possible not only to isolate facies complexes and sedimentation environments, but also to link them spatially. Usage of sequence stratigraphy methods made it possible to qualitatively dissociate the sufficiently massive deposits of the Abu Gabra formation into synchronous intervals and determine the most promising areas of hydrocarbons accumulation.

This article is devoted to examine the pressure behavior during well tests at the system with two finite-conductivity vertical hydraulic fractures. An approximate numerical solution of the problem is obtained, simu-lation of studies by interference test is conducted. This was done by correlating the amplitude of the pressure in the observation well at the distance between two fractures with the fracture flow conductivity. The established mathematical model is used to interpret field case which have been get by method of interference test on a deposit with the low permeable reservoir.

The article presents a description of the settlement method of necessary injection rates calculation, which is depended on the injected water migration into the surrounding wells and their mutual location. On the basis of the settlement method the targeted program of geological and technical measures for regulating the work of the injection well stock was created and implemented by the example of the BV7 formation of the Uzhno-Vyintoiskoe oil field.

The kinetic constants of the decomposition reaction of an aqueous solution of a binary mixture used for thermal-pressure induced impact on the bottomhole zone during stimulation of oil inflow are determined. The obtained constants allow predicting the effects of pressure and temperature growth in the reaction zone. A mathematical model is proposed that makes it possible to describe the kinetics of the reaction taking into account the escape of gas.

The issue of reliability assurance while constructing the oil field facilities by the example of West Siberian oil fields is considered. In particular, attention is paid to the problems that arise during the stage of mechanized crude oil production in case of high water cut of well produce, in severe natural and climatic conditions areas. The whole field development technological chain from the stage of crude oil production to the stage of crude-oil gathering and transportation was analyzed. For every stage the major factors, decreasing the system reliability, were determined and the suggestions for the elimination of these factors or reducing their negative influence were made. A number of possible measures for improvement field facilities construction reliability and profitability are indicated.

The article discusses the differential equation of the stationary two-phase filtration, the obtained as a spe-cial case of nonlinear non-stationary equations. It is established that for the formulation of solutions it is necessary to use the dependence of water-saturation and oil-saturation factors on the pressure of water pumped into the reservoir. With the advance bringing into the development of the injection well, it has been established, that the water and oil flow rates and the water-cut coefficient depend on the selected coefficients of the relative permeability and the outer boundary of the drainage area. The merits and demerits of the stationary filtration model are estimated.
