Abstract

Research on fluid migration, particularly hydrocarbon fluids, in various geological structures of Ukraine is one of the leading directions for determining their influence on the development and genesis of mineral deposits. The formation of vein mineral complexes is one of the indicators of post-formational processes of fluid transfer of matter and mechanisms of fracture healing in sedimentary rocks, and it is characteristic of the terrigenous flysch deposits of the Dukla and Krosno structural-facial units of the Ukrainian Carpathians. The formation of mineral veins represented by calcite and quartz, including the “Marmarosh diamonds” type, in the deposits of the region’s flysch formation during the Oligocene-Miocene period was influenced by regional fluid-dynamic processes. The formation of several generations of secondary inclusions in “Marmarosh diamonds” indicates that the transverse Rakhiv-Tysia deep fault, within the zone of influence of which the studied veins are located, developed under conditions of periodic stress release, resulting in the formation of fault dislocations. Considering the cyclical (stage-by-stage) process of filling fault dislocations with mineral matter, quartz crystals formed during the final stages of the vein structure development within the zone of influence of the Rakhiv-Tysia transverse deep fault. The results obtained allow for the determination of specific local and regional mineral formation trends characteristic of the Krosno and Dukla structural-tectonic zones. The data obtained from complex precision studies should be applied as a prospecting criterion for hydrocarbon accumulations within the region.

Abstract

The influence of the chemical composition of marine and continental waters on the formation and transformation of clay minerals is examined using the Miocene evaporites of the Carpathian Foredeep and the Upper Neoproterozoic-Lower Cambrian evaporites of the Salt Range Formation (Pakistan) as case studies. Evidence for continental-water inflow in the Miocene evaporitic deposits of the Carpathian region is recorded in all facies based on geochemical indicators and, in the gypsum–anhydrite and halite facies, also by clay mineral assemblages atypical for these settings.

The principal controls on clay-mineral transformation under hypersaline conditions are identified, with brine concentration in both the evaporitic basin and buried deposits being the dominant factor, while interaction with organic matter against a background of volcanic activity represents the second most important control. Clay minerals from both the Badenian rock salt and the Upper Neoproterozoic-Lower Cambrian marls of the Salt Range Formation interacted with epigenetic organic matter: in the Carpathian region, regional thrusting created migration pathways for bitumens into Miocene evaporites, whereas the Sawal marl succession likewise contains bituminous layers and is regarded as a petroleum source rock.

Genetic affinities and differences among clay-mineral assemblages formed at successive stages of brine concentration in the Upper Neoproterozoic-Lower Cambrian evaporitic basin of the Salt Range Formation are demonstrated. The presence of identical intermediate transformation products indicates that the same controlling factors operated in the Biliyanwala salt succession as in the Sawal marl succession, whereas the absence of defective structures and the higher crystallinity of clay minerals in the salt unit confirm the decisive role of brine concentration in governing transformation processes.

Abstract

The paper considers the role of pore structure in the formation of local thermobaric conditions that may support methane generation in fossil organic matter through chain free-radical reactions. The gas–organic matter system is treated as a heterogeneous dispersed medium in which nano-, micro- and mesopores cannot be described only by bulk pressure and temperature. A dimensionless pore-pressure coefficient π = Pp/P∞ is used, where Pp is the pore pressure and P∞ is the geostatic pressure. The value π = 1 corresponds to equality between pore and geostatic pressures, whereas π < 1 indicates a pore-pressure deficit; therefore, 1 − π can be interpreted as a relative measure of rarefaction. Model data are analysed for pore diameters of 0.5, 1, 2, 5, 10, 20, 50, 100 and 1000 nm within the depth range 0–10 km. Additional trends are discussed for peat and brown coal, medium-rank coal and anthracite under heat flows of 40 and 100 mW/m2. The results show that pore size is the main factor controlling the deviation of pore pressure from geostatic pressure. In pores of 0.5–2 nm, π remains far below unity even at a depth of 10 km, whereas pores of 100–1000 nm approach a quasi-equilibrium state. A higher heat flow slightly lowers π in small pores and can promote the formation of free radicals, but this effect is secondary to the geometric restriction imposed by pore size and shape. The evolution from peat and brown coal to anthracite is therefore interpreted not only as a change in sorption capacity and transport properties, but also as a change in the abundance of local pore domains favourable to the mechanical destruction of organic matter, radical stabilization, and methane generation. The proposed interpretation links pore-scale pressure heterogeneity with the kinetics of homolytic reactions and provides a basis for further quantitative modelling of methane formation in a three-phase coal matrix.

Abstract

In the western part of Upper Jurassic – Lower Cretaceous carbonate complex of Ukrainian Precarpathians, are the depression sediments, represented by open shelf deposits and reef destruction products. They were opened by wells in area adjacent to the Krakovets fault, their recorded length reaches 100 km. Numerous oil-shows and small deposits are known in the upper part.

Since the depressional formations of the Upper Jurassic are promising for hydrocarbons, detailed comprehensive studies are a necessary prerequisite for the effectiveness of further geological work. A detailed characteristic of these sediments is also necessary for regional and interregional correlation.

Based on the analysis and comparison of a complex of published data and the results of our microfaunal and microfacies studies, the structure and composition of depression formations of the Upper Jurassic – Lower Cretaceous carbonate complex in Ukrainian Precarpathians have been clarified. They consist of the forereef facies of Oxfordian (Boniv suite), Kimmerigian (Morantsy suite), Tithonian – Lower Berriasian (Lower subsuite of Carolina suite) and the open-marine formations of Upper Berriasian – Early Valanginian. (Upper subsuite of Carolina suite). These deposits extend in a narrow strip along the Krakovets fault and with regional erosion are covered by Neogene sediments. The full section of depression sediments has been opened by five wells. A detailed lithological and paleontological characteristic of these sediments at the macro- and microscopic levels is provided, zoning by foraminifera and tintinnids is characterized, correlative microfacies with planktonic microorganisms are determined.

The occurrence of depression deposits is prognosed under the thrust structures of the Carpathians. It expands the prospects of oil and gas potential of the region and needs further comprehensive research by various geological and geophysical methods.

Abstract

New data obtained as a result of geological mapping conducted in recent years, together with the analysis of literary sources, made it possible to distinguish the Late Cretaceous-Paleogene active margin of the Alkapa microcontinental terrane. Fore-Alkapa accretionary wedge composed of both the Pieniny Klippen Belt and Monastyrets Nappe were assigned to the Alkapa margin. Syn-orogenic formations (coarse-grained deposits of the trench-like basins in front of the wedge) and post-orogenic formations (deposits of the wedge-top basins) were distinguished. Geological evolution was considered in the context of the development of the entire Carpathian region.

The sedimentary successions of the Pieniny Klippen Belt and Monastyrets Unit were deposited in the basin located between the Alcapa and Tisza-Dacia terranes. Pieniny Klippen Belt composed of intensively deformed deposits had been formed as an accretionary wedge in front of the Alcapa active margin in the pre-Eocene time. Deformed deposits of the Pieniny Klippen Belt are unconformably covered by the post-orogene Eocene wedge-top sediments (Vulhivchyk Formation). Pieniny accretionary wedge was progradated onto the Monastyrets Basin. The stratigraphic succession of the Monastyrets Unit is characterized by coarsening upward from the Paleocene–Eocene thin-bedded flysch up to the Middle–Upper Eocene syn-orogenic massive sandy deposits. In addition, there are shallowing upward of these deposits. These patterns are characteristic of a growing accretionary wedge. Wedge progradation cased detaching of the deposits, synsedimentary uplifting and shallowing of the Monastyrets basin. Finally, the Monastyrets Nappe was added to the Fore-Alcapa accretionary wedge. Closuring of the Monastyrets “between-terrainian” flysch basin at the late Eocene and progradation of the Fore-Alcapa wedge onto the continental slope of the Tisza-Dacia Terrane at the Oligocene suggest the collision of the Alcapa and Tisza-Dacia Terrane.

Abstract

The coal in the Dnieper brown coal basin contains high-quality bitumen, which is a raw material used in the production of lignite wax for a number of industries. A quantitative assessment of the variability of bituminousness from a number of indicators, with a possible genetic interpretation, revealed a dependence of bitumen yield on the petrographic composition of coal, as well as on some of its chemical and technological parameters. A positive correlation was found between bituminousness and the content of microcomponents of the liptinite group (primarily bituminite-desmite), the yield of volatiles, and the elemental composition of coal. Conversely, an inverse dependence was found between bitumen content and ash content and ash-forming components, as well as between bitumen content and humic acids. Insignificant correlations of bitumen with some rare elements in the Verkhniodniprovske deposit were revealed. Based on an analysis of the distribution of bitumen across the Verkhnyodniprovske deposit, as well as the Leifman – Vassoevich and Werner coefficient values, it can be concluded that marine conditions stimulate the transformation of organic matter, particularly the formation of bitumen. A slight decrease in bituminosity was detected in the marginal parts of the Verkhnyodneprovske deposit. It is hypothesised that these areas of peatland were situated on the slopes of an erosion-tectonic paleovalley, where the impact of seawater on the transformation of organic matter was less significant. The positive impact of marine conditions on bitumen formation is also illustrated on the example of the Novomyrhorod, Myronivske and Orativske deposits. No dependence of bituminosity was found on the thickness of the seam, the rocks of the roof and base, or the depth of its occurrence.

Abstract

An important factor in overcoming the crisis in the economy of Ukraine during the post-war reconstruction period is the proper provision of the economy’s needs in mineral and raw materials resources and their effective use.

In the geological and industrial assessment of coal deposits, they should be considered as complex coalbed methane. Coalbed methane as an unconventional source of hydrocarbons can be an alternative to electricity production by burning coal and a valuable energy and chemical raw material that can be successfully used in the energy and chemical industries.

The complex of factors influencing the total gas content (methane content) of a coalbed is analyzed and summarized: the complexity of the geological and tectonic structure of the territory; the degree of coal bearing capacity; the degree of metamorphism; gas capacity, composition and physicochemical properties of coal; porosity, sorption properties, density, permeability and fracturing of coal and host rocks; depth of coal seams; presence and thickness of overlying sediments; hydrogeological conditions; occurrence of methane weathering zone.

Purpose: assessment of methane production prospects of the coal-bearing stratum of the Tyagliv deposit (mine field Tyagliv No. 1) of the Lviv-Volyn basin according to geological criteria.

The Tyagliv deposit is the most gas-bearing in the Lviv-Volyn basin. The distribution of gases is characterized by extreme instability in area and depends on the tectonic structure. The article considers the gas-bearing and technogolic features of coal seams and Carbonaceous sandstones of the Serpukhovian and Bashkirian Carboniferous stages. Within the Tyagliv No. 1 mine field, coal seams b4, n9, n8в, n8, n7в, n7 (Buzhanskaya Formation of the Middle Carboniferous) and intervals of Carbonaceous sandstones belonging to the Serpukhovian Lower Carboniferous (n06Sn7) and the Bashkirian Middle Carboniferous (n8Sn9, n9Sb1, b1Sb4). were studied. Gas-bearing schemes of these objects are presented. Based on the presented material, an assessment of the prospects of the area of the Tyagliv No. 1 mine field was made, taking free and sorbed gas in coal-bearing strata into account.

According to all the proposed geological criteria, the coal-bearing strata of the mine field Tyagliv No. 1 may be promising for methane production. Taking into account the geological and exploration characteristics, we can speak of real prospects for independent methane production.
