Abstract

The energy components of sustainable development in the countries of the European Union have been analyzed, in particular according to goal 7 “Affordable and clean energy”, directions of the European Green Deal, taking into consideration synergies and compromises, as well as cross-cutting factors in achieving the specified indicators. 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.

Abstract

It is shown that the problem of the nature of water in oil and gas fields must be solved in an inextricable connection with the genesis and synthesis of natural hydrocarbons in the Earth’s bowels. The work offers an original solution, based on a new theory of the synthesis and genesis of hydrocarbons (oil, gas, etc.): abiogenic-biogenic dualism, which asserts that giant and supergiant oil and gas fields were formed from inorganic and organic original hydrocarbon-containing substances under the influence of abiogenic high-thermobaric deep fluid in harsh physical, physicochemical and geological conditions of the earth’s crust. Since the abiogenic high-thermobaric deep fluid contains hydrogen H+ and OH-containing anions, the described mechanism for the interaction of positively charged ions: C+, H+, CnHm+-radicals with the formation-synthesis of a complex hydrocarbon mixture such as gas, oil, bitumen, etc. must be logically supplemented by a reaction: Н2О → Н+ + ОН−. As a result of this complex physical and chemical process, the maximum concentration of (OH−) anions accumulated in the oxidation zone, which after the disappearance of the electric field become neutral and interact with each other according to the scheme: ОН + ОН = Н2О2 – hydrogen peroxide, which is an unstable compound, which decomposes into Н2О + О. Oxygen atoms became the starting substances for the formation of macro- and microcracks in these cavities under harsh conditions of rocks of the carbonate or quartz-carbonate type, etc., much less often – perfect mineral crystals, which with their defects in the process of growth (synthesis) captivate and preserve substances in the system (proper hydrocarbons and water). Тherefore, it was established for the first time that the natural water of oil and gas fields has a dual lithospheric-asthenospheric nature, while the lithospheric part is dominant, the isotopic composition is a mixture of these waters, and the deuterium isotope is more chemically active in complex physical and chemical processes, which run through the bowels of the planet. The obtained original data will contribute to the solution of Ukraine’s serious problem with energy carriers: natural gas, oil, coal and drinking water.

Abstract

It was established that in order to avoid errors in the interpretation of paleotectonic conditions of salt formation based on fluid inclusions in halite, the primary stage of the research should be the genetic identification of the sedimentation textures of halite and fluid inclusions in this mineral. For the thermometric study of inclusions and to determine the depth of the sedimentation basin based on the obtained data, only thermal test chambers are suitable which provide the possibility of observing groups of inclusions in different zones of sedimentary halite, as, for example, in the micro thermal test chamber designed by Prof. V. A. Kalyuzhny.

In the course of the research, the equipment of the thermometric method, which is based on the use of a microthermal test chamber designed by V. A. Kalyuzhny, was modernized. In particular, the material of the thermal chamber (stainless steel) was replaced with copper, which made it possible to avoid excessive thermal gradients into chamber and to increase the permissible heating rate by 20 times due to the higher thermal conductivity of copper. For the same purpose, the glass optical windows of the camera were replaced with leukosapphire windows, which have a much higher thermal conductivity. The measuring system of the installation is made on a miniature platinum resistance thermometer with an electronic measuring unit. These improvements made it possible to achieve high system stability and good reproducibility of measurement results.

Using the thermometric method, it was established that the temperature of sedimentation at the bottom of the Badenian salt basin of the Carpathian region was 19.5–20.5; 20.0–22.0; 24.0–26.0 °C, and on the surface of the brine was 34.0–36.0 °C. On this basis, a model of the basin with a pronounced thermocline and a total thickness of the water column of up to 30 meters was built, which is the most likely to establish the features of sedimentation. Crystallization of halite at different depths in basins with a thermocline can explain the presence of so-called “low-temperature” (24.0–25.0 °C) and “high-temperature” (37.8–42.6 °C) bottom halite in a number of ancient salt-bearing basins.

Abstract

The publication is a review that presents in a concise form information about the chemical composition of living matter components and the mechanisms of their transformations, the result of which is the geopolymers formation. Among geopolymers, humic substances, including humic and fulvic acids, attract our attention. The relevance of this review lies in the importance of understanding multidirectional reactions, the result of which is the secondary polymerization of organic matter chemically active components that have passed the biodegradation barrier at the stage of sedimentation and diagenetic transformations. Humic substances, in their turn, are precursors of kerogen, therefore, an understanding of reaction mechanisms and their products provides complete information about the conditions of various types of kerogen formation, which are characterized by different ability to produce oil and gas. We paid special attention to polyphenols, which have high chemical activity and the ability to react with increasing molecular weight. In addition to the traditional Maillard reaction, among the condensation mechanisms we considered oxidative crosslinking of phenols, oxidative condensation of polyunsaturated fatty acids, and esterification of fatty acids with phenols. For each mechanism, the conditions for its implementation and probable contribution to the formation of humic substances are briefly considered. Analysis of probable mechanisms of formation of humic substances showed that condensation reactions can occur under geochemical conditions of sedimentation and early diagenesis. At the same time, their speeds are low, and the precursors necessary for the reactions, formed as a result of biological degradation, are contained in very small concentrations. We conclude that kerogen contains two components – primary, which enters its structure without any significant changes, and secondary, which is the result of a series of complex multidirectional reactions.

Abstract

An analysis was made as to the usage of geological-geophysical methods for studying of low-amplitude tectonic dislocations in coal-enclosing massifs. As a result of geophysical researches conducted at coal fields, mine fields and mine workings of the Lviv-Volyn Coal Basin, the methods of field observations by means of natural electromagnetic and electric fields were worked and their results were processed for prediction and diagnostics of tectonic dislocations with a break of continuity and zones of unstressed state. To raise the efficiency of the methods of electromagnetic fields it is recommended to carry out measurements at wide frequency range (from 5 to 50 hz) with orientation of the antenna according to the world sides (azimuthal surveying) and at narrow frequency range (5; 12.5; 17 khz) with the southern orientation of the antenna (frequency sensing). According to azimuthal surveying one can calculate the vector of maximum intensity of electromagnetic radiation. It was ascertained that over distinctive dislocation one can observe the variation in the direction and absolute value of vectors. Displacement of the anomaly of electromagnetic radiation intensity at different frequency range by profile indicates the direction of dipping of the area of displacement of dislocations with a break of continuity. The method of natural electromagnetic impulse field of the Earth fixes both the dislocations, distinguishes by geological-geophysical methods before, and new low-amplitude dislocations and stressed zones.Tectonic dislocations, that are displayed only in Paleozoic deposits, are distinguished by contrast anomalies of electromagnetic radiation in electromagnetic field, but dislocations with a break of continuity that cut the Mesozoic thickness and in most cases are accompanied by zones of rock fracturing in the Cretaceous deposits: by wide destructive anomalies. Plots over worked-out lavas with stressed deformational state are characterized by strongly differential abnormal values of the intensity of natural impulse electromagnetic field of the Earth. The method of natural electric field allows us to detect zones with water-bearing fracturing rocks in the upper part of the geological section. Methods of natural impulse electromagnetic field of the Earth and natural electric field may be used both independently and in the complex with other geophysical methods for detection and tracing of tectonic dislocations and dynamically-unstressed zones. Thus, the optimum apparatus-methodical complex for detection and diagnostics of low-amplitude dislocations with a break of continuity of coal-enclosing series by electromagnetic methods (NIEMF, NEF) was formed and effective methods of field observations, processinf and interpretation of data were developed.

ON KUZIAN SUITE OF THE MARMAROSH NAPPE OF THE UKRAINIAN CARPATHIANS

Abstract

In 1957, L. G. Tkachuk and D. V. Gurzhiy have singled out the Upper Paleozoic Kuzian suite in the north-western part of the Marmarosh crystalline massif at the Rachiv area. It consists of phyllites, limestones, quartzites and dolomites. The suite is widely distributed in the Dilovets subcover of the Marmarosh nappe at the Rakhiv and Chyvchynian areas. There are two alternative points of view upon the age of the Kuzian suite. Some geologists attribute it to Paleozoic time (Upper Devonian-Lower Carboniferous), the others attribute its lower part to the Upper Paleozoic, and the upper one: to Triassic. One can notice the existence of the different estimation of the lithological composition and different estimation of the lithological composition and the volume of the Kuzian suite.Thus, in 1970 A. K. Boiko has devided it into Muntselulska (Lower) phyllite-quartzite one of Paleozoic age and Upper (Triassic) phyllite-carbonate one for which he saved the name Kuzian suite. The important is that a stratigraphic interruption was fixed between the above-mentioned units. The phyllite-carbonate Kuzian suite is dated on the basis of transgressive occurrence of the middle Triassic dolomites on it, discovery of the post-Paleozoic mosses in its lower part at the Soimul Mountain, and in the upper one: the complex of spores and pollen of Mesozoic age. Geologists, that do not recognize the idea of belonging of the part of suite to Mesozoic, indicate the next contradiction. If we accept the Mesozoic age of the Kuzian suite, so we must affirm that carbonate series of Middle Triassic-Jurassic were deposited on the massif at the same time, and 5–8 km southerly, the regional metamorphism of the Kuzian suite occurred within that zone (by the way, according to some facts at an interval of 148–178 and 175–181 mln years, and according to another information: at an interval of 196–221 mln years. This remark is not correct because the age of the Kuzian suite is Lower Triassic (251.9–247.2 mln years), but metamorphism occurred much later. In those sections where the Kuzian suite lies on the Muntselulska one, basal conglomerates consisting of pebbles and quartzitic fragments of underling suite are present in its bottom. Rocks of the Muntselulska and Kuzian suite are similar by their metamorphism intensity. For the Mesozoic Kuzian suite the manifestations of the main magmatism are characteristic, unlike the Upper Paleozoic acids. The facts testify to that the Mesozoic Kusian suite is existing, but there is a certain indefinity as to its finer dividing, stratigraphic volume and correlation with deposits of Middle Triassic. To avoid confusion, it is expedient to alter the name of the Mesozoic Kuzian suite and to name it, for example, Neo-Kuzian.

Abstract

The object of research was the Ustynivka area, which is located in the north-eastern part of the Dnipro-Donets basin on the border between the northern board and axial part of the region.

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. The location of exploration and prospecting boreholes is proposed. Considering the displacement of the vaults of gravigenic structures with depth, to open the productive stratum in the apical parts of the uplifts, we recommend drilling inclined boreholes in the southwestern direction. Tasks for industrial development of deposits of Voronove structure are defined.

Abstract

A study of natural waters within the influence of the Dobrivlyany gas condensate field, located in the Dobryany and Dobrivlyany area village councils of the Stryi district of the Lviv Region of Ukraine, was conducted.

The purpose of the work is to evaluate the geochemical indicators of natural waters based on our own research, to find out the role of natural and man-made factors in the formation of the chemical composition of waters.

The objects of the research are surface waters and groundwaters within the influence of the Dobrivlyany gas condensate field.

Research results. In the research area, as well as in the Bilche-Volytsia zone in general, there are unfavorable conditions for active water exchange and the formation of fresh infiltration waters, since the upper part of the geological section is characterized by clayey Neogene deposits. The depth of penetration of fresh hydrocarbonate-calcium waters here does not exceed 70 m. The small thickness of the zone of active water exchange is one of the indicators of difficult water exchange in the subsoil, therefore, favourable conditions for the preservation of hydrocarbon deposits.

As a result of exploratory work, the Dobrivlyany gas condensate field was opened in 2016. During 2016–2019, 7 boreholes were drilled, and industrial gas inflows were received from horizons LD-9, LD-12, and N1kr+K2. In tectonic terms, the deposit is confined to the northwestern part of the Kosiv-Ugersko subzone of the Bilche-Volytsia zone of the Carpathian Foredeep.

Observation of the macro component composition of groundwater from the wells of the Dobrivlyany gas condensate field indicates the stability of the hydrodynamic conditions of the deposit and, accordingly, the low variability of their geochemical characteristics. Direct hydrogeochemical zonation is clearly manifested in the increase in water mineralization with depth: for the LD-9 horizon at depths of 800–840 m, it varies within the range of 34.74–48.55 g/dm3, for LD-12 at depths of 995–1010 m – 33.82–73.70 g/dm3 and for N1kr+K2 at 1131–1158 m – 67.49–100.31 g/dm3. The content of Br and J doubles with depth. All waters are of the chloride-calcium type (according to Sulin), and genetic indicators vary within narrow limits (rNa/rCl – 0.82–0.91; Cl/Br – 216–315; rSO4 ∙ 100/rCl – 0.003–0.5) and indicate their thalassogenic sedimentogenic origin. The analysis of research results showed that underground waters belong to a single hydrodynamic system, and are characterized by the same type of water according to their chemical composition.

According to the qualitative characteristics of groundwater from an ecological borehole and a well in the Dobrivlyany village remain clean and meets regulatory requirements for drinking water. At the same time, water from a well in Vivnya village is characterized by a high content of nitrates (2.28 maximum permissible concentration), which is caused by the location of the pig complex “Halychyna-Zakhid” LLC on the outskirts. Increased content of organic substances in the waters of two wells of the Railiv village was also established, in which the permanganate oxidizability reaches 1.08–1.24 maximum permissible concentration, and, according to Hygienic requirements for drinking water intended for human consumption, is unfit for consumption. The waters of the Kolodnytsia River are chloride-hydrocarbonate sodium-calcium (calcium-sodium) in composition, while the waters of the Stryi River and the Zhizhava River are calcium bicarbonate.

Abstract

The construction of the new Beskydy railway tunnel, which revealed the indigenous deposits of the Krosno formation of the Ukrainian Carpathians, provided an opportunity to obtain new results from the study of another prospective oil and gas-bearing areas of the flysch formation within the Krosno structural-facies unit. There is a second tunnel in length in Ukraine and passes under the Verkhovyna watershed ridge of the Ukrainian Carpathians. Its section is represented by the rocks of the Krosno formation, namely the stratification of sandstones, argillites and silt stones. There are two fracture zones have been indentified here, in which developed veinle-impregnated mineralization of ore (sulfides) and non-ore (calcite and quartz type of the “Marmarosh diamonds”) minerals. Calcite and quartz formas monominerals veins and in paragenesis calcite-quartz type of the “Marmarosh diamonds” ‒ sulfides. Quartz occurs in the form of splice sand well-faceted crystals, transparent, in yellow, brown, black, green colour. Calcite of a milky, translucent colour in the form of veins, veinlets, impregnation, powder on quartz, druz. Contains significant impurities of magnesium, manganese and iron which means the presence of a rhodochrosite-magnesite-siderite component. Hydrocarbon fluids are present in all calcite and quartz crystals of the “Marmarosh diamonds” type. By chemical composition, it is methane with impurities of higher hydrocarbons (up to hexane). Sometimes the manifestations of the outflow of a black substance with the smell of oil from the cracks in the veinlet-impregnated mineralization are recorded studied rock complexes of the flysch formation of the Krosno zone of the Ukrainian Carpathians (construction area of the new branch of the Beskydy railway tunnel), which acquires an important genetic significance.
