Due to the decline in gas and condensate production at the Orenburg oil and gas condensate field, the priority area of activity of Gazprom PJSC and Gazprom Dobycha Orenburg LLC is the reproduction of the mineral resource base and the achievement of maximum component recovery factors to provide the Orenburg gas and chemical complex. The solution to this problem is directly related to the involvement of the unique reserves of hard-to-recover oil (matrix oil, high-molecular raw materials), confined to the gas-saturated part of the Orenburg field, in the production and deep complex processing. Hard-to-recover oil has a variable composition – from high-bituminous oil in fractured-porous and porous low-permeability reservoirs to liquid traditional oil in porous and large-pore permeable reservoirs. This paper analyzes the results of estimating the reserves of matrix oil, the predicted resources of associated components of matrix oil (metals) and the retained gas reserves, which are not included in the assessment of reserves.

The development of oil and gas condensate fields is accompanied by phase transformations of reservoir mixtures, i.e. the transition of condensate from the gas state at the formation pressure below the condensation start pressure and its reverse evaporation when the maximum condensation pressure passes. Dynamic condensation leads to a decrease in permeability in the bottomhole zone, as a result, the productivity of the well is reduced.We have used the method of gas-dynamics research at steady-state filtration conditions in our work in order to minimize the influence of retrograde processes and the justification of the technological well operation conditions of usage gasdynamics research at steady-state filtration conditions.Especially, set up a problem is important in conditions of low-permeability reservoirs with a significant potential content of condensate in the formation gas.

The development of methods and means to improve the efficiency of the mining facility is aimed at improving the efficiency of the use of raw materials concentrated in deposits of natural and man-made origin. This increase in efficiency is manifested through maximizing the content of commercial ore shipped for processing, creating prerequisites for increasing the shipment of commercial ore and increasing the productivity of the processing plant. Maximization of the content in commercial ore is based on the developed scheme of cyclical increase in the efficiency of resource potential use for the entire period of field development, supplemented by an improved method of current mining planning based on anisotropy of contents and dynamic conditions.

Extraction Of Metals

The state of the mineral resource base of hydrocarbons in recent years has been characterized by a decrease in proven reserves and extremely low rates of their reproduction. In Western Siberia, as in other oil-bearing provinces of Russia, economically profitable oil reserves are decreasing. It is obvious that the development of the fuel and energy complex is becoming more focused on the development of hard-to-recover reserves, which account for almost 2/3 of the proven oil reserves. Technologies for the extraction of such raw materials are characterized by higher capital costs, which requires the search for new ways to increase the profitability of projects. One of these areas is the extraction of metals from the associated water of oil and gas fields. In this paper, the possibility of using the technology for extracting lithium from the associated waters of the Orenburg oil and gas condensate field is evaluated, and the boundary conditions for the implementation of this technology are determined.

Low Permeability Reservoirs

The 21st century witnessed the development of the oil extraction industry in Russia due to the intensifica- tion of its production at the existing traditional fields of Western Siberia, the Volga region and other oil-extracting regions, and due discovering new oil and gas provinces. At that time the path to the development of fields in Eastern Siberia was already paved. The large-scale discoveries of a number of fields made here in the 70s-80s of the 20th century are only being developed now. The process of development itself is rather slow in view of a number of reasons. Create a problem of high cost value of oil extraction in the region. One of the major tasks is obtaining the maximum oil recovery factor while reducing the development costs. The carbonate layer lying within the Katangsky suite is low-permeability, and its inventories are categorised as hard to recover. Now, the object is at a stage of trial development,which foregrounds researches on selecting the effective methods of oil extraction.

Internationally the research of low permeability oil reservoir is a difficult point in the exploration and development of oil and gas field. This thesis, based on the research methods of low permeability reservoirs at home and abroad, summaries several major problems encountered in the process of low permeability oil exploration and development under the current technical conditions as well as the corresponding, but more effective technical measures that need to be constantly improved. And that exploration and development of low permeability of the reservoir will be the main battle field for some time in the future of oil exploration and development.

The analysis of the state and prospects for the development of the mineral resource base of the Vorkuta region of the Komi Republic, belonging to the Arctic zone, was carried out. It is shown that the coking coal deposits of the Pechora basin, the development of which is the basis for the existence of the city of Vorkuta, were and still are the most impor-tant ones. The reserves of coking coal are significant, however, the supply of them to operating mining enterprises is becoming more and more limited. To maintain and develop coal mining, it is necessary to build new mines. Along with the coal deposits, the Vorkuta region is of great interest in relation to other minerals. In the Kosyu-Rogovsk and Koro-taikha depressions, there are potential oil and gas-bearing structures, on the western slope of the Polar Urals – barite deposits, gold, chromium and copper occurrences, deserving further geological study and prospecting works. For a more complete disclosure and development of the mineral resource potential of the Vorkuta region, the extension of transport infrastructure is of great importance. The implementation of plans for the construction of railways, access to the Northern Sea Route, can contribute, in particular, to increasing the volume of coal production and wider supplies of coal using sea transport, and raising the investment attractiveness of the Arctic territories.

After the dissolution of the U.S.S.R., Russia is repositioning itself as a major political-economic actor in the Eurasian geo-region. These aspirations are commensurable with Russian history, geography, and rich mineral resource base, specifically energy. To a large extent, Russia's resurgence has been propelled by extraordinary reliance on oil and gas buttressed by high global energy prices. Russia's political-economic ambitions, posturing, and recent improvements are found in stark contrast with its mediocre ratings in social and environmental performance. The study explores strategic attractiveness, cost, and risk of doing business, and reveals that Russia trails Germany and U.S.A., key aspirational comparators, in critical global competitiveness rankings. It also lags behind China, a major comparator. Under high energy prices, Russia appears capable of maintaining a certain degree of global competitiveness and improvements, although tempered by growing politic-economic strategic ambitions. The study calls for reforms and strategic improvements in developing human capital and innovations toward sustainable global competitiveness.

Low Permeability Reservoirs

Ordos Basin is the second largest sedimentary basin in China with very rich oil and gas resources. The exploration targets are typical reservoirs of low permeability. To determine the accumulation mechanism of tight sandstone reservoir, thin section, SEM, numerical calculation were used. The result showed that sandstone should be ultro-low permeability reservoirs with the high content feldspar and lithic arkose or feldspathic litharenite. The reservoir became tight while oil filling, buoyant force is too small to overcome the resistance of capillary force. Therefore, overpressure induced by source rock generation is the accumulation drive force.
