Based on the well-known results of studies of the ether-geosoliton concept of the growing Earth, the article presents the conclusions that made it possible to propose a model of thermonuclear synthesis of chemical elements that form renewable reserves of developed oil and gas fields. It was revealed that local zones of abnormally high production rates of production wells and, accordingly, large cumulative production at developed fields in Western Siberia are due to the restoration of recoverable reserves due to geosoliton degassing. Therefore, when interpreting the results of geological and geophysical studies, it is necessary to pay attention to the identified geosoliton degassing channels, since in the works of R. M. Bembel and others found that they contributed to the formation of a number of hydrocarbon deposits in Western Siberia. When interpreting the results of geological-geophysical and physicochemical studies of the fields being developed, it is recommended to study the data of the ring high-resolution seismic exploration technology in order to identify unique areas of renewable reserves, which can significantly increase the component yield of hydrocarbon deposits.

In the southeast of Western Siberia, the most studied are the Upper Jurassic deposits, most of the oil and gas fields being confined to them. However, the probability of discovering new hydrocarbon deposits in the Upper Jurassic horizons is extremely small. Therefore, of great importance is finding new hydrocarbon deposits in less studied deep-lying complexes. The article considers the development of a criterion for determining the saturation type of the terrigenous reservoirs in the Hettangian-Aalenian deposits in the southeast of the West Siberian sedimentary basin. We use the example of the Ust-Tym megadepression, a large depression located in the central part of the Tomsk region. The Lower and Middle Jurassic sections are represented by the Urman and Togur formations, Salat formation (Peshkov formation is its isochronous analogue) and Tyumen formation, and characterized by the alternation of predominantly sandy (potential reservoirs) and argillaceous-carbonaceous (seals) sequences. In the studied interval, tests were carried out in just a few wells, for which reason the identification of deposits and promising objects is complicated. Determining the type of reservoir saturation will significantly improve the assessment of oil and gas potential. As a result of interpreting lateral logging sounding data, the geoelectric parameters of the invasion zone and undisturbed formation were reconstructed for the Lower Jurassic and Aalenian deposits. Based on the well logging data interpretation by means of numerical inversion, we obtained the criterion for the saturation type of the reservoirs (Ju11-17) in the Hettangian-Aalenian complex. The boundary resistivity values for the oil-saturated reservoirs vary from 8 to 20 ohm∙m, while for the water-saturated ones they do not exceed 5 ohm∙m.

Practical value of this work consists in increasing the efficiency of exploration for oil and gas fields in Eastern Baghdad by optimizing and reducing the complex of well logging, coring, sampling and well testing of the formation beds and computerizing the data of interpretation to ensure the required accuracy and reliability of the determination of petrophysical parameters that will clarify and increase proven reserves of hydrocarbon fields in Eastern Baghdad. In order to calculate the most accurate water saturation values for each interval of Zubair formation, a specific modified form of Archie equation corresponding to this formation was developed.

Abstract In the article, in relation to the Arctic zone of the Russian Federation, a new method of forecasting hydrocarbon deposits based on computer geodynamic modelling procedures is considered. It is less expensive compared to field and analytical methods. The approbation of the method on the example of the Laptev Sea shelf zone showed a good interpretability of its results and their compliance with the forecast obtained by other methods. The rationality of using six geodynamic indicators for forecasting: the distributions of vortex structures of the velocity vectors of horizontal shear deformations and vortex structures of normal linear deformations; the values of the velocity vectors of horizontal shear deformations and velocity vectors of horizontal normal linear deformations; the distributions of the anomalous gravitational field in isostatic reduction and the reduced temperature. The sequence of stages in determining the potential of hydrocarbon deposits in the studied territories is described, which is associated with the solution of six interrelated sequential tasks: the choice of local territorial areas of optimal size - the calculation of geodynamic indicators – the allocation of homogeneous territorial clusters – the detailing and improvement of geodynamic indicators – the determination of the potential of oil and gas fields in the cluster – the localization of oil and gas fields in each cluster – construction of a digital forecast map of the location of oil and gas fields in the study area.

In the method of seismic location of oil and gas (SLONG), intended for predicting the oil and gas prospects of objects based on the data of seismic exploration method CDP-2D, the length of the laterally allocated sections of the presence of hydrocarbons is determined by statistical processing of all graphs of the energy distribution by depth of micro tremors. However, in this case, the results of processing depend on the repetition factor of impulse accumulations of fluctuations used. Therefore it is proposed to use a different approach to determine the length of the lateral sections of the presence of HC based on the processing of micro tremors recorded during CDP-2D, according to the method proposed by G.V. Vedernikov, E.A. Khagoev and T.I. Chichinina. As a result of applying this technique, it was found that all oil and gas fields are accompanied by anomalies in the micro tremors field in terms of energy and spectral characteristics of vibrations. Not stopping on the possibility of solving the inverse problem, we only note that according to this provision, the presence of a deposit should lead to anomalies in the micro tremors field and, in particular, to an increase in the energy oscillation. Therefore, if the presence of a deposit is established in any way, then we should expect the appearance of a section with an increased energy oscillation, which can be used to estimate the length of the deposit laterally. The fact of the presence of a deposit can be established by the results of processing the same CDP-2D profile using SLONG technology. If a positive SLONG result is obtained, a section with an increased energy of micro tremors should appear on the corresponding section of the profile, which will lead to the solution of the problem. Key words: Location, microtremors, length, anomaly.

The Impact

In the process of extraction, collection, transportation and primary processing of hydrocarbons, the lands of the fields are often damaged. For the further operation of the oil field, it is necessary to carry out not only reclamation of disturbed lands, but also oil-contaminated lands formed as a result of accidental spills. The natural environment of Western Siberia is a fragile environment and interference in its existing balance as a result of accidental spills of oil products and pollution of land and water bodies leads to negative consequences for the flora and fauna. If the impact on the natural environment during the development of oil and gas fields during the placement of oil field facilities can still be considered as permissible, then the ingress of oil products into the environment should be considered as negative with far-reaching consequences.
