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.

Based on new geological and seismic data, using an integrated approach, the zones of distribution and the boundaries of thinning out of silty sand reservoir rocks of Vogulkinskaya strata were mapped, four traps and two zones (Ourinskaya, Eastern Tolumskaya), which are perspective for hydrocarbon deposits search, were distinguished. In Bazhenov horizon, the zones of development of anomalous sections and bituminous sediments were mapped, laying above Bazhenov formation, which are perspective for hydrocarbon deposits search. Recommendations for further exploration are given.

This paper discusses the issues of technological regulation and the methodology of research of complex reservoirs with hard-to-recover reserves on the example of fields in the West Siberian oil and gas province. The integrated analysis was based on a certain sequence that allows you to systematize and structure the data that was later added to the database of Petrel, CorelDRAW, and Isoline-GIS software systems. Informative constructions were performed and additional statistical data processing was performed in the «Statistica-Base» program.

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.

Modeling of the most common types formation of anticlinal and uplift-thrust tectonic structures was carried out with using optical polarization and tectonic-sedimentary methods based on seismic sections analysis of various areas and deposits located in the West Siberian oil and gas basin that were selected for examples. Experiments with using the optical-polarization method allowed us to research the nature of the stress-regime arising in the gelatin models of the sedimentary cover due to the growth of anticlinal blocks and uplift-thrust dislocations. By the level of tangential stresses and orientation of isoclines in optical models, zones of probable tectonogenic fracture and the direction of cracks are predicted. 2D tectonic-sedimentation modeling made possible to explain the mechanism of formation of “rootless” uplifts, zones of subsidence or decompression in sediments, the principle of tectonic “pump” function, and to obtain dependencies between size and shape of uplift, density and opening of cracks formed above, to calculate the value of fracture “porosity”, as well as lateral dimensions of zones of tectonogenic fracturing. 3D tectono-sedimentation modeling allowed to link hydrography of the earth surface of the simulated area with decompression of zones that came to the surface in the models. These zones of decompression can serve as a search sign for exploration of highly productive zones containing hydrocarbon deposits.

The probability estimation of oil and gas inside certain area is essential for decision making on the industrial exploitation of oil and gas bearing features. A quantitative assessment of the hydrocarbon contour mapping accuracy using ground-based spectrometric measurements, remote, geological and geophysical data requires a special validation procedure. Its purpose is to evaluate achieved accuracy and reliability as well as the conformance to specified requirements. The input data for validation of the hydrocarbon deposit contour by field spectrometry are the one points’ locations relative to the other contours detected by independent methods, such as remote, geological and geophysical. As the field spectrometry performed along spatial trace, the geometric drifts of other methods’ cross-points are estimated. The algorithm for the validation of hydrocarbon deposit contour mapping by field spectrometry, remote, geological and geophysical data is proposed in this paper. The algorithm was tested on over the Novotroitsky and East Rogintsy hydrocarbon deposits (Ukraine). Measurements along 14 spatial traces over the Novotroitsky’s deposit and 28 traces over the East Rogintsy’s one was carried out to perform validation. The average error probability was 0.28, which demonstrates an admissible reliability of hydrocarbon deposits contours’ mapping by field spectrometry data. The preliminary validation estimates engagement during the hydrocarbon deposits mapping provides the fact-based statistical consistency of the quantitative measurements received. In addition, it is possible to filter the outliers reasonable before final information product release, which will enhance the overall reliability.
