Abstract:
Due to the severity and persistence of the global financial crisis started in 2007, central banks all over the world have adopted Unconventional Monetary Policies (UMPs), including negative policy rates, longer-term refinancing operations and large-scale purchases of financial assets. In this study, by referring to a time-series regression analysis with Newey-West correction, we evaluate the impact of UMPs implemented by the Eurosystem over the period 2008-2019 on the stocks of euro area banks’ deposit from households and non-financial corporations. The analysis of the effects of UMPs on the stocks of banks’ deposit represents a particularly innovative aspect of this research, where most of the scientific literature focuses on deposit interest rates. Our results suggest that the UMPs conducted by the Eurosystem have had a significant positive impact on euro area bank deposits, with particular reference to the relationship between Longer-term refinancing operations and Household overnight deposits, as well as between Securities held for monetary policy purposes and deposits from Households (total deposits) and from Corporates (overnight deposits).

Abstract:
Desiccation (water loss by drying or freeze-thaw sufficient to generate matric suction), can influence the performance of a tailings deposit both positively and negatively. The significance of desiccation is largest in tailings that have been dewatered prior to deposition, by thickening or filtration. Such tailings can be “stacked” or deposited with a significant slope, which usually implies that a substantial volume of tailings remain above water. Under such conditions the tailings, by accident or by design, may undergo desiccation before burial by fresh tailings. Desiccation can contribute substantially to strength, above and beyond the contribution arising from increase in density, through stress history effects. For some deposits, it is required practice that at least some tailings undergo desiccation to improve, particularly when those tailings for a structural part of a deposit. If, however, tailings remain exposed to the atmosphere in an unsaturated state for some period of time, this may have potential negative consequences through oxidation of sulphide minerals and the formation of acid drainage. This paper describes previous research on the strength gained through desiccation in tailings, and on modelling work that incorporates unsaturated soil phenomena into consolidation analysis. Both types of research are applied to a real field site, providing an example of how novel improvements to tailings management can arise out of application of principles of unsaturated soil mechanics.

Abstract:
Topical issues concerning the possibilities of effective development of unconventional gas fields, in particular gas hydrate as an element of Ukraine’s energy security, are covered. Attention is drawn to the need for an integrated approach to the development of unconventional hydrocarbon deposits using project management methods. The main challenges, opportunities, scenarios of energy security of Ukraine are studied. Priority tasks in the gas sector are analyzed in accordance with the implementation of the New Energy Strategy of Ukraine for the period up to 2035 at the stage “Optimization and innovative development of energy infrastructure (until 2025)” and “Ensuring sustainable development (until 2035)”. Peculiarities of development of unconventional hydrocarbon deposits at each stage of management – discovery, evaluation, development, production and closure of the project are determined. The purpose of the article is a comprehensive substantiation of organizational and technological decisions to increase the efficiency of development of offshore gas hydrate fields in comparison with other unconventional gas fields.

Abstract:
Abstract Shale formations have been recently treated only as source rocks and sealing packages mainly of conventional deposits. At present shales, which have a considerable concentration of highly mature organic matter appearing in complexes of over 30 m thick are used as unconventional sources for natural gas production with the use of advanced drilling technologies. Natural gas production in such rock formations necessitates performing a horizontal section in the borehole and a big number of hydraulic fracturing jobs. The unconventional shale gas deposits have been prospected also in Poland for a couple of years. Exploration works mainly concentrate on a vast area passing from Pomerania through Mazowsze to the Lublin region in Poland. The analysis of the geologic analyses reveals that the most perspective are shales in the Lower Paleozoic at a depth of 2500 m in the eastern part to about 4000 m in the western part of the area. The paper is focused on the quantitative and qualitative evaluation of environmental impact of natural gas exploration works from unconventional deposits. Special attention was paid to the hydraulic fracturing jobs in shales, which create particular hazard for water and soil environment. These hazards already appear at the stage of preliminary works, when big quantities of chemicals and water for frac jobs are stored in the rig area, and then, during realization of works, when the spent hydraulic fracturing fluid may penetrate the water-bearing horizons in the caprock. The composition of fracturing fluid used in Gapowo B-1A well are given along with the results of chemical analyses of a few parts of spent fracturing fluid samples pumped out from the borehole. The fluid turned out to be high in salt (high specific electrolyte conductance (SEC) and total dissolved substances (TDS) and a high toxicity for most of the living organisms). For this reason the spent fracturing fluid should not enter the environment without control.

Abstract:
The first industrial oil in the Timan-Pechora oil and gas province was obtained in 1929. By now more than 230 hydrocarbon deposits have been explored in the Province. A significant part of these deposits is under development. At the same time, the originally explored total resources have been developed in terms of oil only by 50%, in terms of gas - by about 30%. The remaining unexplored part of the initial total resources is forecast to be located in difficult unconventional bedding conditions, in particular, in the domaniсites of the Upper Devonian period. The so-called shale oil and gas are associated with them. The forecasting, exploration, and development of oil and gas deposits in the domaniсites require new methodological and technological solutions. The article discusses the problems of unconventional hydrocarbon development using the example of the domaniсites of the Timan-Pechora oil and gas Province.

Abstract:
The paper provides new findings on vitrinite obtained from well-core samples of the Devonian and Carboniferous sedimentary strata of the oil-gas prospective fields, both in the eastern and western sides of the Dnieper-Donets Depression (DDD), with a focus on unconventional hydrocarbon prospecting. The organic matter was identified microscopically and vitrinite reflectance was systematically measured. In the deposits studied, vitrinite represents different types of organic macerals; disseminated vitrodetrinite being still dominant. Measurements of vitrinite reflectance strik-ing off different DDD surfaces reveal high average dispersion means ranging 0.5 to ~7.0%. This characterizes variable level of the organic matter maturity and its different property to generate hydrocarbons. However, in general, the vitrinite reflectance tends to gradually increase with depth, meaning gradual maturation of the organic matter from the younger beds to older ones, and a temperature rise conditioned by a temperature gradi-ent. Organic matter immature to generate significant amount of gaseous hydrocarbons is deposited in the DDD at the depth of 3000 m. However, down the depth of 2100 – 2300 m, the average vitrinite reflectance increases up to the values sufficient to consider organic matter mature, and to generate wet and dry gas. Thus, it is inferred to be prospective to explore for new shale gas deposits below the hypsometric level. On the other hand, the irregular dispersion of organic matter maturation in the DDD necessitates further detailed research, namely, into map-ping potentially prospective areas of gas generation.

Abstract:
Among the numerous human remains found in circular pits belonging to the fourth millennium BCE cultures north of the Alps, there are many examples of bodies laid in random (or unconventional) positions. Some of these remains in irregular configurations, interred alongside an individual in a conventional flexed position, can be considered as a ‘funerary accompaniment’. Other burials, of isolated individuals or multiple individuals buried in unconventional positions, suggest the existence of burial practices outside of the otherwise strict framework of funerary rites. The focus of this article is the evidence recently arising from excavation and anthropological studies from the Upper Rhine Plain (Michelsberg and Munzingen cultures). We assume that these bodies in unconventional positions were not dumped as trash, but that they were a part of the final act of a complex ritual. It is hypothesised that these bodies, interpreted here as ritual waste, were sacrificial victims, and a number of possible explanations, including ‘peripheral accompaniment’ or victims of acts of war, are debated.

Abstract:
An integrated stratigraphic analysis of a ~350 ft drill core from Upton County (Texas) has revealed pervasive variability of several key siliciclastic and carbonate lithofacies in vertical section, where organic-rich siliceous mudrock beds alternate with aluminum-rich mudrocks and calcareous gravity flow deposits. Sediment chemistry, especially major and trace elements derived from x-ray fluorescence, captures this variability with high sensitivity. The high frequency chemostratigraphic variability appears to be cyclic, and it is interpreted to represent the first example of deep-water Late Pennsylvanian cyclothems for the Midland Basin. Positive trace metal (Mo, Cr) correlations to total organic carbon and gamma ray response in siliceous mudrocks, in conjunction with abundant pyrite, indicate bottom-water anoxia and possibly euxinia within the basin. The influence of glacial ice-sheets on the water level of the global ocean, in concert with local oceanographic gradients, regional tectonics, and tropical paleoclimate, constitute the primary controls on lithofacies and chemostratigraphy. The results of this study have implications for understanding the depositional history of the Midland Basin, as well as for identifying horizontal drilling zones for resource development.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior<br>O presente estudo aborda a caracterização faciológica e quimioestratigráfica do intervalo de folhelhos betuminosos da Formação Tremembé (Oligoceno da Bacia de Taubaté), bem como a avaliação econômica desses depósitos na região de Pindamonhangaba e Moreira César, SP. A partir da coleta sistemática de amostras de testemunhos do poço MOR-SP, foram determinados os teores de COT, S e RI, assim como dados de Pirólise Rock-Eval. Com base nesses dados seis unidades quimioestratigráficas(designadas de I a VI a partir da base) foram definidas no intervalo de cerca de 40 metros de espessura. Dados previamente estudados dos poços TMB-SP e PND-SP foram utilizados para correlação dessasunidades.Com base nos dados de Pirólise RockEval foi possível quantificar o volume de óleo potencialmente recuperável através do aproveitamento industrial dos folhelhos betuminosos. No intervalo mais promissor (unidades VI e V), compreendendo uma seção de cerca de 17 metros de espessura, o rendimento de óleo é de cerca de 25,7 milhões de barris por km2, na área do poço MOR-SP.Os dados obtidos apontam para uma importante jazida não convencional de folhelho betuminoso (oilshale), cujo aproveitamentoeconômico, se executado,requerirá, além de novas soluções tecnológicas, a implementação de ações de forma a minimizar os impactos sociais e ambientais de uma possível operação extrativa desse recurso.<br>The present study deals with the faciologic and chemostratigraphic characterization of the oil shale interval of the TremembéFormation(Oligocene, TaubatéBasin), and the economic evaluation of these deposits in the Pindamonhangaba and Moreira Cesar,SP regions. From the systematic sampling of the MOR-SP borehole, we determined TOC, S and IR contents, as well as data from Rock-Eval pyrolysis. Based on these data, six chemostratigraphic units (designated from I up to VI in the base) were defined in the interval of about 40 meters in thickness. Data previously studied of TMB-SP and PND-SP wells were used for correlation of these units. Based on data from Rock-Eval pyrolysis, it was possible to quantify the volume of oil potentially recoverable through industrial exploitation of bituminous shale. In the most promising interval (units V and VI), comprising a section of about 17 meters thick, the oil yield is about 25.7 million barrels perkm2 in the area of MOR-SP well. The data point is an important deposit of non-conventional bituminous shale (oilshale), which sees an economic use, if implemented, will require additional new technological solutions, the implementation of actions to minimize the social and environmental impacts of a possible extractive operation of this resource.

Abstract:
Shale gas development rapidly transformed energy production when new techniques emerged in the late 1990s and 2000s. The combination of high-volume hydraulic fracturing and horizontal drilling, or “fracking,” allowed development in vast, previously inaccessible, “unconventional” oil and gas deposits. Fracking has been welcomed by many national governments as a purportedly low-greenhouse-gas-emitting, energy-security-providing windfall. But it has simultaneously motivated vehement local opposition, to some surprising political effect. Many jurisdictions around the globe now have bans on the practice. This chapter explores shale gas development as a contested “sociotechnical imaginary,” an imagined form of social order reflected in technological projects. Drawing on the controversy in New York in the United States, it demonstrates how the “drill, baby, drill” imaginary was debunked as groups framed it as inherently risky and dangerous, and sought to empower institutions supporting an alternative imaginary.
