Assessment of hard-to-recover oil reserves production potential in Tomsk region

The development of the licensed areas, profound geological exploration, enhanced oil recovery due to innovative technologies introduction and revitalization of oil production from unconventional horizons could significantly increase the oil production in the Tomsk region. This article deals with the issue of oil producing companies’ affairs of the Tomsk region for the past 10 years and proves the oil production potential growth through the development of both conventional and hard-to-recover unconventional oil reserves, concentrated in the Bazhenov and Tyumen Formations, as well as in the Lower Jurassic sediments. The Russian Federation is far behind from the economically developed countries, especially from the United States, in the exploitation of hard-to-recover unconventional hydrocarbon resources. The «shale revolution» was determined by a complex of financial and tax incentives introduced for oil and gas companies. However, this was mainly beneficial for medium and small sized companies. Therefore, both the business entities and regional authorities should increase the investments spending, as well as introduce the additional tax incentives considering the quality and type of potentially available raw hydrocarbons produced in the region, in contrast to the declared benefits in the territory of Eastern Siberia. The introduction of tax incentives justified by the authors, and the implementation of public-private partnership mechanism will ensure the profitability of marginal and hard-to-recover deposits development of the Tomsk region in the long run, which in its turn, should ensure the stability of the economic development of the reviewed subject of the Russian Federation

Mechanisms of proton-proton inelastic cross-section growth in multi-peripheral model within the framework of perturbation theory. Part 2

We demonstrate a new technique for calculating proton-proton inelastic cross-section, which allows one by application of the Laplace' method replace the integrand in the integral for the scattering amplitude in the vicinity of the maximum point by expression of Gaussian type. This in turn, allows one to overcome the computational difficulties for the calculation of the integrals expressing the cross section to sufficiently large numbers of particles. We have managed to overcome these problems in calculating the proton-proton inelastic cross-section for production (n \le 8) number of secondary particles in within the framework of \phi^3 model. As the result the obtained dependence of inelastic cross-section and total scattering cross-section on the energy \sqrt{s} are qualitative agrees with the experimental data. Such description of total cross-section behavior differs considerably from existing now description, where reggeons exchange with the intercept greater than unity is considered.Comment: 11 pages, 10 figures (v3: some inaccuracies corrected

Economic tools for realization of methane production project on Kuzbass coal deposits

Environmental issues and, above all, issues related to the release of greenhouse gases into the atmosphere, such as coal bed methane, actualize the challenge of searching a variety of options for its disposal. The difference in the macroeconomic, industrial, geological and infrastructural features determine the need to choose the most cost-effective option for using of methane emitted from the coal deposits. Various economic ways to improve the profitability of production are viewed on the basis of the analysis of methane production project from Kuzbass coal deposits, Kemerovo region, Russia

Production operation of small petroleum enterprises in Tomsk region

Implementing resource-innovative strategy to develop Russian fuel-and-energy sector implies the promotion of small oil production enterprises developing fields with the reserves of less than 5 mln. tons. However, the efficiency of such enterprises, investigated on the example of Tomsk region (considering the indexes of oil extraction, growth of reserves, amount of capital expenditures and geological surveys), signifies the presence of definite tendencies. Consequently, management decisions concerning economic, organizational, financial and fiscal character should be taken in order to eliminate detrimental factors

Financial Aspects of Technological Concept for Energy Efficiency Enhancement during Stripper Wells Development in Tomsk Region

The issue of operating costs cutting in terms of falling oil prices on the world market actualizes the challenge to find technological solutions to reduce electricity consumption during well operation. This is especially important for stripped-wells of small deposits in Tomsk region. The correlation analysis between the cost of oil production, electricity, heat and fuel consumption during the extraction of one ton of oil allowed the authors to focus on the financial aspect of such technological solutions like periodic well operation in the Shinginskoye field as well as to recommend the application of this method at the other fields in Tomsk region

On some fundamental peculiarities of the traveling wave reactor

On the basis of the condition for nuclear burning wave existence in the neutron-multiplicating media (U-Pu and Th-U cycles) we show the possibility of surmounting the so-called dpa-parameter problem, and suggest an algorithm of the optimal nuclear burning wave mode adjustment, which is supposed to yield the wave parameters (fluence/neutron flux, width and speed of nuclear burning wave) that satisfy the dpa-condition associated with the tolerable level of the reactor materials radioactive stability, in particular that of the cladding materials. It is shown for the first time that the capture and fission cross-sections of $^{238}$U and $^{239}$Pu increase with temperature within 1000-3000K range, which under certain conditions may lead to a global loss of the nuclear burning wave stability. Some variants of the possible stability loss due to the so-called blow-up modes (anomalous nuclear fuel temperature and neutron flow evolution) are discussed and are found to possibly become a reason for a trivial violation of the traveling wave reactor internal safety.Comment: 44 pages, 19 figures, 2 table

On the contact detection for contact-impact analysis in multibody systems

One of the most important and complex parts of the simulation of multibody systems with contact-impact involves the detection of the precise instant of impact. In general, the periods of contact are very small and, therefore, the selection of the time step for the integration of the time derivatives of the state variables plays a crucial role in the dynamics of multibody systems. The conservative approach is to use very small time steps throughout the analysis. However, this solution is not efficient from the computational view point. When variable time step integration algorithms are used and the pre-impact dynamics does not involve high-frequencies the integration algorithms may use larger time steps and the contact between two surfaces may start with initial penetrations that are artificially high. This fact leads either to a stall of the integration algorithm or to contact forces that are physically impossible which, in turn, lead to post-impact dynamics that is unrelated to the physical problem. The main purpose of this work is to present a general and comprehensive approach to automatically adjust the time step, in variable time step integration algorithms, in the vicinity of contact of multibody systems. The proposed methodology ensures that for any impact in a multibody system the time step of the integration is such that any initial penetration is below any prescribed threshold. In the case of the start of contact, and after a time step is complete, the numerical error control of the selected integration algorithm is forced to handle the physical criteria to accept/reject time steps in equal terms with the numerical error control that it normally uses. The main features of this approach are the simplicity of its computational implementation, its good computational efficiency and its ability to deal with the transitions between non contact and contact situations in multibody dynamics. A demonstration case provides the results that support the discussion and show the validity of the proposed methodology.Fundação para a Ciência e a Tecnologia (FCT

Analysis of the oil companies’ performance (on the example of Tomsk Region)

The implementation of socio-economic development programs of Tomsk region is largely determined by the activities of oil companies. Analyzing the outcomes of their activity is necessary to reveal the basic trends and influencing factors for the development of measures to support basic industry. The analysis shows that there are few successful companies carrying out the license agreements and plans for oil extraction, as well as investing in exploration and development of new deposits. As a consequence, forecasts for growth of hydrocarbon reserves in the long run and the implementation of the energy strategy of Tomsk region for the period up to 2020 are not promising. The current situation is primarily caused by current tax and investment policies towards small subsoil users who operate small and medium-sized fields in complicated industrial and geological conditions. As a result, we have an increase in costs for growth of hydrocarbon reserves per meter of deep drilling and the costs of preparing each ton of oil, which ultimately leads to lower profitability of oil companies
