The success of drilling oil and gas wells is largely determined by the presence of high HC-content and permeability of the reservoir at the point of penetration. For a reliable study of these characteristics should be used microseismic emission and the scattered reflection waves. For their observation, selection and positioning in geomedium we developed technology “Seismic Location of Emission Centers” and “Side-View Seismic Location”, which significantly extend the range of problems solved during seismic exploration of hydrocarbon deposits. Examples of application of these technologies in the exploration and development of hydrocarbon deposits are provided.

Hydrocarbon Deposits

Nadym-Pursk oil and gas region has been one of the main areas for the production of hydrocarbon raw materials since the sixties of the last century. A significant part of hydrocarbon deposits is at the final stage of field development. An increase in gas and oil production is possible subject to the discovery of new fields. The search for new hydrocarbon deposits must be carried out taking into account an integrated research approach, primarily the interpretation of seismic exploration, the creation of geological models of sedimentary basins, the study of geodynamic processes and thermobaric parameters. Statistical analysis of geological parameters of oil and gas bearing complexes revealed that the most promising direction of search are active zones — blocks with the maximum sedimentary section and accumulation rate. In these zones abnormal reservoir pressures and high reservoir temperatures are recorded. The Cretaceous oil and gas megacomplex is one of the main prospecting targets. New discovery of hydrocarbon deposits are associated with both additional exploration of old fields and the search for new prospects on the shelf of the north. An important area of geological exploration is the productive layer of the Lower-Berezovskaya subformation, in which gas deposits were discovered in unconventional reservoirs.

The predominant area of application of the developed methodology is the construction of the distribution of the geodynamic state of the developed hydrocarbon fields in oil and gas basin, and the identification of the corresponding distribution law. A number of the hydrocarbon deposits in terms of geological conditions of occurrence, structure and other parameters are geodynamically hazardous during their development. The Federal Law «On Subsurface Resources» (Article 24) requires conducting a complex of geological, surveying, and other observations sufficient for ensuring a normal technological cycle of work, and the prediction of hazardous situations. The developed methodology based on the construction of aggregated additive models for each reservoir and field is presented. It includes four sequential stages (24 operations): first — prepare geodynamic data; second — determine the geodynamic state of productive strata; third — find the geodynamic state of the developed deposits subsoil; fourth — build the distribution of the bowels geodynamic state of these fields for the entire oil and gas basin and identify the relevant distribution law. Oil and gas basin in the west of the Orenburg Region (Volga — Ural and Caspian oil and gas provinces) is considered as an example of implementation. Unique data of twenty geodynamic parameters of 320 productive strata (56 fields) were used. It is revealed that in accordance with the Pearson criterion, the theoretical data with a high confidence probability (95 %) correspond to the law of normal distribution. Developed methodology has significant technical and economic advantages, since it allows to identify the geodynamic state of productive strata and subsoil of the fields being developed, to identify hazardous geodynamic processes and to choose rational modes for the development of hydrocarbon deposits.

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.

Thickness of reservoir has a direct and close contact with oil and gas exploration and development, reservoir thickness is directly related to success and failure of the exploration and development. The main problem of the Seismic exploration is the limit of the resolution, geophysical workers have done a lot work, but the effect has been not obvious. Mainly to the following questions: 1、it is difficult to determine the boundaries of the reservoir；2、the limits of the resolution still exists. In this paper, through the study of the high-resolution sequence Stratigraphy and fine calibration, we used the sequence boundary and flooding surface to build the initial model, and then the density inversion was done to indentify the oil and gas reservoir. On the basis of the inversion, the density ranges of the sandstone in the sequence were calculated through geostatistics, and then we correctly calculated the thickness of the sandstone in every sequence, in this way we not only solved the problem of reservoir boundaries, but also improved the resolution.

The main provisions of the current paradigm of prospecting, exploration and production of hydrocarbons, which are based on petrophysics and seismic exploration, are considered. It is shown that within its framework it is possible to apply any new ideas about the structure of natural reservoirs, the origin and migration of hydrocarbons. This paradigm will make it possible to move to the preparation of a qualitatively new resource base of the oil and gas complex through the discovery and development of hydrocarbon deposits in the best natural reservoirs with the best petrophysical parameters, high density of light oil and gas reserves, and high well production rates. New highly profitable hydrocarbon deposits will be discovered in areas with developed infrastructure, mainly in well-known oil and gas provinces.

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.
