|Southern-eastern part of Kaliningrad region - new openings and oil prospect perspectives|
|For a long time (until the mid-1980s), the territory of the eastern part of the Kaliningrad region was not considered among the promising directions for increasing the region's raw resource quantity. It was believed that the geological prerequisites of this region (low thickness of the sedimentary cover, remoteness from the axial most submerged part of the Kursh Depression with the optimum depth of burial of source rocks and other factors) do not contribute enough to the formation of oil accumulations. However, the subsequent discoveries of a number of oil fields made it possible to reconsider the views on the prospects of this area of the Russian Baltic Syneclise. The results of geological exploration work of recent years are considered. The example of the Ryazan accumulation (Kursh Depression Baltic Syneclise) gives a geological description of typical objects of oil prospecting, promising local uplifts and future research directions.
Keywords: geological prospecting, oil accumulation, oil-bearing prospects, Baltic syneclise.

|Potential of geological and economic research concerning the adoption of administrative decisions on development of raw material bases of hydrocarbons|
|The goals and objectives of the procedure for geological and economic assessment of the resource base of hydrocarbons, its role and place in making managerial decisions on a wide range of problems associated with the development and operation of the mineral and raw materials complex of Russia are considered. The features of the geological and economic evaluation are applied to oil and gas objects. The main groups of risks associated with the implementation of oil and gas production projects are considered, the potential of probabilistic methods of their accounting is critically analyzed.
The most important factors affecting the financial and economic efficiency of oil and gas projects and their investment attractiveness (the state of the hydrocarbon market, the tax system, the availability of transport and production infrastructure) are described, and the potential of geological and economic analysis as a tool for minimizing their negative impact is explored.
The role of the classification of reserves and resources as a basic element of the geological and economic analysis of the resource base of hydrocarbons is considered, attention is focused on the shortcomings from this position of its new version, introduced since 01.01.2016.
Keywords: geological and economic evaluation, hydrocarbon raw materials, classification of hydrocarbon reserves and resources, probabilistic methods.

|Probabilistic methods application for oil geological research|
|The potential of involvement of probabilistic methods is discussed with regard to the specifics of oil geological issues arising from the need to consider sophisticated and multifactorial processes, information about which is most often very limited and characterized by a high level of uncertainty. The features of the mathematical framework that implements this approach are analyzed; and the methodological challenges and technological limitations are investigated. The conditions and criteria ensuring correct application of this tools and the reliability of the results and estimates, which directly determine the effectiveness of managerial decisions in the oil and gas sector formed on their basis, are analyzed.
Keywords: oil and gas geology, estimation of reserves, geological and economic evaluation, probabilistic and statistical methods, the probability density function.

|On the basis of the results of geological and economic evaluation of subsoil blocks within the Timan-Pechora province the most significant determinants of commercial interest of subsoil users and perspectives of involving oil resources in the study and subsequent development are investigated, i.e. structure of the resource base from geological point of view (size and depth of occurrence of the projected objects, productivity of host deposits), the availability of transport and production infrastructure, and the level of the tax burden. The influence of some of these factors is subject to regulation. The possible ways of increasing the investment attractiveness of oil assets that can stimulate licensing process in the region are described.

|Geological and economic characteristics as a basis for evaluation of petroleum production prospects in Eastern Siberia|
|The hydrocarbon resources and petroleum production prospects in Eastern Siberia are characterized from the geological and economic positions. The relationship between investment projects and structure of resource base is analyzed. It is shown that the amount of proven oil reserves within the region does not provide projected production volumes and filling of the Eastern Siberia - Pacific Ocean pipeline by oil. The extensive exploration is required to increase active reserves. The large-scale development of gas resources is only possible providing the solution of the problem of disposing of the helium, which content is unique in the region.

|New classification of reserves as a means for tax system optimization in oil and gas production: current situation and prospects|
|The elements of a new classification of hydrocarbon reserves, which characterize the economic component of oil and gas objects, are considered.
The new classification’s opportunities in terms of reliable estimation of investment attractiveness of the hydrocarbon resources are analyzed on the
example of oil objects within the territory of the Nenets Autonomous District and the Komi Republic (Timan-Pechora oil and gas province). Some
drawbacks of the classification, associated with the lack of tax component in the proposed system of estimation, are marked. The system of tax
optimization for investment projects in this economic area is proposed, considering the quality of resources, macroeconomic conditions of projects
implementation and state interests in the creation of effective subsoil policy along with budget revenue optimization.

|Geological and economic aspects of developing the hydrocarbon resource base, Kaliningrad oblast|
|The overwhelming majority (76%) of the Kaliningrad oblast reserve fund objects are characterized by the smallest localized recoverable hydrocarbon resources in not excess of 100 thousand t. These objects contain one third of total oil resources of identified and prepared structures of this region. Within the Kaliningrad region characterizing by the predominance of the smallest objects in the structure of the prospective resource base, the profitability of developing the considerable part of oil potential will depend on exploration efficiency (mainly on wildcat drilling success). Tax privileges are necessary for decreasing the profitability threshold of reserves and including a part of the resource base unattractive for investors in industrial turnover. Their volume must be determined individually by each object and must depend on oil cost and the cost price of its production. For this region, in which all producing oil is exported, the only essential direction of forming such privileges is a severance tax.
