It is shown that in 2019, the EU’s energy dependence on energy imports by types of fuel was: oil and oil products – more than 90 %, natural gas – about 80 %, solid fossil fuels – about 40 %. During 2014–2019, the decrease in the use of solid fuels (−4.9 %) was compensated by the increase in the use of renewable energy sources and biofuels (+2 %), as well as by the increase in the use of natural gas (+3.4 %), which could not cause a significant reduction in the share of fossil fuel use and a reduction in emissions of greenhouse gas – carbon dioxide CO2, at the same time the total dependence of EU countries on fuel imports increased from 54.4 to 60.7 % (by 6.3 %), which negatively affects the achievement of energy indicators of sustainable development. In 2019, the total share of renewable energy sources was 19.7 % with an ambitious goal of reaching 32 % in 2030. The energy components of sustainable development in Ukraine are analyzed. It is shown that, in particular, according to goal 7 “Affordable and clean energy”, the progress of the specified indicators is characterized by a low probability of achievement; in 2019, the share of coal imports in Ukraine was 68.6 %, oil – 76.7 %, natural gas – 45.1 %, and the total share of imports of primary energy resources by 2030 should be reduced to a level of not less than 12 % and the share of energy from renewable sources should reach 17 %. Based on a comparison of the energy components of sustainable development in the countries of the European Union and in Ukraine, the main requirements for energy indicators and tasks of sustainable development for Ukraine and its regions are proposed. These requirements differ in the addition of energy indicators and tasks of sustainable development in Ukraine with indicators that are monitored in the countries of the European Union and were not used in Ukraine before, as well as the introduction of indicators that take into consideration the energy characteristics of the regions of Ukraine. An adaptive structure of energy tasks and indicators for the regions of Ukraine is proposed.","PeriodicalId":176324,"journal":{"name":"Geology and Geochemistry of Combustible Minerals","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116828428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is known that peat has a pronounced ability to physical sorption and chemisorption, as a result it is able to accumulate a significant amount of metals, including dangerous – heavy, toxic and radioactive. Peat is used as an energy raw material, in recent years – as a raw material for the chemical and pharmaceutical industries. Thus, this geochemical research has scientific and applied importance for a wide range of industries and for environmental monitoring. The range of peat applications directly depends on the concentration of trace elements. The basic geochemical characteristics of peat lowland type in Lviv Region were found out. In general, the content of elements in the studied peat has concentrations lower than сlarkes in comparison with the lithosphere, soils and terrestrial plants. Lithophilic Sr, Yb, Be, Ba, siderophilic Mo, Co, and chalcophilic Pb, Ag are actively concentrated in comparison with clarkes in the lithosphere, soils, plant ashes and relative to background values in the soils of Ukraine. According to the results of a comprehensive analysis of the content of microelements in lowland peats of Lviv Region, three elements with high concentration were identified – Molybdenum, Strontium and Lead. Significant uneven distribution of microelement concentration with depth and area of distribution and high indicators of Mo, Yb, Sr, Be, Co, Ag, Ba, Pb relative to clarkes of lithosphere, soils, plant ash, etc. have been established. Comparison of patterns of accumulation and scattering of elements in peat with lithosphere, soils and terrestrial plants shows that peat is characterized by its own specific set of storage elements, there are specific patterns of accumulation and scattering of elements. Thus, peat has a clear geochemical structure that distinguishes them from mineral soils and lithosphere.","PeriodicalId":176324,"journal":{"name":"Geology and Geochemistry of Combustible Minerals","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128070027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper considers the geological zoning of oil and gas fields and deposits of solid combustible minerals, as well as their reserves and production. It is shown that the reserves of the main primary energy resources in Ukraine many times exceeds the extraction and has significant opportunities to increase due to the use of substandard combustible minerals. The principles of ecologically safe conversion of substandard combustible minerals in terrestrial and underground conditions are presented. The importance of energy utilization of methane from coal deposits, arrays of such man-made carbon-containing materials as coal mining waste, coal beneficiation, oil refining, etc. was noted.

In fields that are being operated for a long time, the prospects for industrial hydrocarbon accumulation can be associated with secondary gas traps of non-traditional type, in particular, technogenic ones, which are formed in low-pore reservoirs. A detailed analysis of the geological conditions of the East-Novoselovskyi field was carried out. They contribute to the formation of additional gas resources (“behind-pipe reserves” category), as well as the establishment of geological-industrial indices of the perspectivity for the formation of technogenic deposits was carried out. The purpose of the work is geological justification and finding perspective zones for the accumulation of behind-pipe reserves through the formation of technogenic deposits under the impact of a geomechanical factor, using the example of the East-Novoselovskyi oil-gas condensate field. For the geological conditions of the East-Novoselovskiy Oil-Gas Condensate Field, producing the additional gas reserves should be expected from technogenic deposits that are located above the industrial horizons that are being developed and formed in low-porous reservoirs under the action of a geomechanical factor, as a result of their decompaction after gas extraction from an industrial reservoir as a result of its compression. In accordance with the conducted research, the most perspective section, from the standpoint of the formation of a technogenic deposit and the accumulation of behind-pipe reserves, within the East-Novoselovskyi Oil-Gas Condensate Field there is the strata identified in the area of wells No. 16, 18, 60, in the section interval at a distance of 92.4 m up from the roof of the horizon (B-3b), which is located from a depth of 2141 m to the roof of the horizon B-3a, at a depth of 2 233 m. It is worthwhile to further carry out appropriate geophysical work for conducting the technological work for the development of technogenic deposits in perspective zones behind the casing column in operated wells. The account of the geomechanical factor opens up the perspective of producing the additional industrial gas influx at the late stages of the development of gas and gas-condensate fields, by predicting the geological conditions for the formation of the improved secondary filtration-capacitive properties favorable to form technogenic gas deposits.","PeriodicalId":176324,"journal":{"name":"Geology and Geochemistry of Combustible Minerals","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121915370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The geological structure of the area is illuminated from positions of gravitational tectogenesis. Two echelons of brachianticlinal uplifts, genetically related to the Krasnoritsk and Muratove-Tuba discharges, have been identified in the Carboniferous deposits. They were formed in nonconsolidated strata under conditions of stretching and rapid lowering of the Dnipro-Donets graben. Seismic surveys have revealed seven anticlines. Their feature is the orientation of structures along arcuate tectonic faults, asymmetry and displacement of anticlines with a depth to the southwest. According to the geomorphological features of the river valley of the Siverskyi Donets, a new uplift is predicted in the lowered block of the Tuba fault. In the Voronove anticline, three gas deposits have been established in the Bashkirian stratum. Nearby are Borivske, Muratove, Yevgeniivka, Krasnopopivka and other gas-condensate fields. Therefore, the gravigenic structures of the Ustynivka area are promising for the discovery of new deposits. Promising horizons of the Bashkirian stratum are at shallow depths: from 2 to 2.5 km. Our estimated gas reserves and resources of the Ustynivka area are 262 and 2100 million m3, respectively. Recommendations are given to clarify the form of gravigenic tectonic faults and related anticlines. The tasks for detailed seismic surveys and drilling are defined.
