Sources of financing technologies for monitoring and purifying atmospheric air (for example, the city of Mariupol)
Authors A. Melikhov, O. Laktionova, V. Kolosok, M. Vereskun and Y. LogvinovSummaryThe search for funding sources for improving the technologies for monitoring and purifying atmospheric air, including closed low-waste ones, is a topical research topic. A closed low-waste technology for utilization of dust and other harmful substances during the operation and repair of equipment of metallurgical enterprises in Mariupol is presented, which complies with international standards and the law of Ukraine “On Waste”. Disposal of dust and other harmful substances is carried out in accordance with sanitary rules, the order of accumulation, setting the maximum amount and organizing the logistics of their transportation. Closed low-waste technology is aimed at monitoring, cleaning, filtering and neutralizing elements of harmful substances, dust, welding aerosols (WA). The sanitary and hygienic conditions of the operating metallurgical enterprises and the population of Mariupol have been significantly improved. Dusty waste containing expensive alloying elements in the solid component (SC) and in the gaseous component (GC) are briquetted into granules, bags, which are reused in metallurgy. To accelerate the implementation of the proposed closed low-waste technology, the authors investigated and proposed to introduce a methodology aimed at optimizing funding sources, including a certain set of borrowed, own, credit and indirect funding sources.

Hydroacoustic impact monitoring of the river environment in the waters of the main navigation fairway of the Pripyat River within the Chornobyl Radiation and Ecological Biosphere Reserve
Authors O. A. Shchyptsov, A. Yu. Gordeev, S. G. Fedoseienkov and O. I. ShundelSummaryThe report presents the results of expeditionary research of changes in the general relief of the river bottom, its geomorphological and lithological features, survey of sunken objects of natural and artificial origin, detected navigational hazards, their nature and location in the investigated area of the main navigation fairway of the Pripyat River within the Chornobyl Radiation and Ecological Biosphere Reserve, that were obtained by scientists of the State Institution “Scientific Hydrophysical Centre of the National Academy of Sciences of Ukraine” (hereinafter – Hydrophysical Centre) in particular in the interests of navigation and hydrographic support of shipping.
A planar hydroacoustic survey of the bottom of the aquatorium with a total area of over 4 km2 was carried out with the use of the ship modular sonar complex developed by the Hydrophysical Centre. As the outcome of cruise a significant amount of hydrophysical (hydroacoustic) data was obtained, sunken objects of natural and artificial origin were discovered and identified. According to the results of research, the spatial distribution of micro-and mesoforms of the bottom relief was defined, the structure of the upper part of the bottom sediment thickness was determined and their lithological classification was carried out.

Lithological and stratigraphic criteria of geohazards within the Dniester river basin
Authors O. Ivanik, O. Shevchuk and S. VasylenkoSummaryThis study is devoted to key lithological and stratigraphic criteria influencing the development of geological hazards in the Dniester river basin. The most important geological outcrops, which are monuments of nature and geology located in the Chernivtsi region on the right bank of the Dniester River, have not been previously studied in terms of stratigraphy. The studied outcrops of Cretaceous and Neogene sediments need to be monitored and preserved. The audit of local stratigraphic subdivisions was carried out and the paleontological characteristics of stratigraphic schemes of the north-western outskirts of the Ukrainian Shield were supplemented. Zonal schemes based on dinocysts and spore-pollen complexes were constructed. The Cenomanian, Turonian (Cretaceous) and Tortonian-Sarmatian (Neogene) deposits, which are exposed on the right bank of the Dniester, are correlated with the same-age deposits of the left bank and adjacent territories.

The valley complex of the geomorpholithosphere of Kyiv and its meaning for monitoring and modelling of natural hazards
Authors A. Komliev, A. Beydik, S. Bortnyk, R. Spitsia, S. Zhylkin and Yu. FilonenkoSummaryThe agglomeration of Greater Kyiv is actively developing. New industrial, civil, transport objects are constantly being built here, which form their naturally -technogenic geosystems (NTG). For its more effective development, the implementation of the rules of spatial planning, which provide for complementary relations between natural and technogenic elements of NTG, is becoming increasingly important. Depths of anthropogenic and technogenic penetration into the earth crust is constantly grow. Therefore of it landscape criteria used in the construction of early Kyiv are now receding and others are more important, such as geological structure, neotectonic and modern tectonic movements and geomorphosystem. The geomorpholithosphere is the materialized “space-time” of the historical-dynamic morphosystem of the Earth. Important elements of the geomorpholithosphere are valleys - day surface and ancient buried. The geomorpholithosphere of Greater Kyiv contains valleys of 12 generations of paleozoic-cenozoic valley formation (PCVF). Were studied the sizes and length of these valleys, their morphological features on the longitudinal and the transverse profile. Their simple and complicated types were identified. Anomalies in the valleys, their system functions, their possible impact on different types of naturally-technogenic geosystems of Greater Kyiv were also studied.

Use of direct hydrocarbon indicators for forecasting hydrocarbons deposits
Authors S. Vyzhva, I. Solovyov, I. Mykhalevych, V. Kruhlyk and G. LisnySummaryBased on the results of numerous seismic surveys conducted on the areas and deposits of the Dnipro-Donetsk depression, an appropriate strategy for detecting hydrocarbon traps in this region has been determined. This takes into account modern requirements for exploration and prospecting of gas and oil deposits. They consist in determining the probable zones of accumulation of hydrocarbons based on the analysis of the structural model. At the same time, the use of direct hydrocarbon indicators to predict structural, lithological or combined traps is also a necessary element in solving this problem. It has been shown that an effective approach to detecting hydrocarbon traps in this region is attribute analysis using seismic attributes such as seismic signal envelope, acoustic impedance or relative acoustic impedance. In most practically important cases, the analysis of the distribution of values of these attributes was sufficient to solve geological problems. At the same time, an example of extracting additional useful information on the spatial distribution of hydrocarbon traps from volumetric seismic images obtained from seismograms of common sources with a limited range of seismic angle inclinations is given. To analyze the distributions of seismic attribute values it is recommended to use geobody technology of geological bodies extracting as the most effective when using volumetric seismic data. Depending on the type of seismic attributes involved in the analysis, the distributions of different properties of rocks are determined, in particular the zone of increased porosity or the presence of hydrocarbons. Analysis with the simultaneous use of several seismic attributes allows to directly identify hydrocarbon-rich geological bodies with high porosity and the like. The paper presents examples of detection of hydrocarbon traps in the areas and deposits of the Dnipro-Donetsk depression, which are confirmed by drilled wells. Generalizations are made on the distribution of promising areas for the presence of hydrocarbons on the northern side of the Dnipro-Donetsk depression and the ratio of this distribution with the identified structural elements of the geological environment.

Petrophysical features of the rocks of the Pliocene deposits of the oil and gas-bearing region of the Nizhnekurinskaya depression
Authors V. Gurbanov, L. Sultanov and A. MammadovaSummaryRecently, based on the oil and gas perspective of deep layers, many geological and geophysical assessments have been carried out in Azerbaijan. Scientific criteria have been prepared, which may be the basis for future research. It was noted that the main oil and gas fields are associated with the South Caspian and the Kursk Basin, which underwent intensive deepening during the Mesozoic era. Despite the high prospects in the central part and the deep layers, while it does not arouse suspicion among researchers, the quantitative and numerical expression has not yet been properly reflected. The article presents the results of analytical generalization of laboratory research data for a complex of petrophysical parameters of reservoir rocks - potential hydrocarbon reservoirs. The object of research was the well-known horizons of the Productive Strata (PT) of the Meso-Cenozoic sedimentary basin. The study area includes actively and long-term developed oil and gas onshore, as well as offshore deep-water fields of Azerbaijan. In the article complex results of the petrophysical testing sample of rocks from taken digging prospecting-development wells from areas of the Lower Kura Trouth which widen productive unit sediments was showed. Defined the collectors' characteristics of rocks. Shows the results of generalization, the analysis and the interpretation of collectors researches more than a thousand samples of sedimentary and magmatic rocks from taken deep exploration wells in the Lower Kura Trouth under high atmospheric pressures and temperatures. For restoration, the physical properties as a result of elastic deformations have been investigated the lithological difference of rock samples from the area of Lower Kura Trouth. Researches have shown that the physical properties of single-nominal and single-old rocks are changed and have different values as the result of geological-physical processes.
