The Ukrainian Sector of the Black Sea and Crimea: the origin, tectonics and evolution
Authors S.M. Stovba, I.V. Popadyuk, O.I. Khriachtchevskaia and P.O. FenotaSummaryThe results of the researches are based mainly on the interpretation of seismic reflection data along 30000 km seismic lines crossing the Ukrainian sector of the Black Sea (BS) and on geological fieldworks in the Crimea Mountains (CM). The Lower – lowermost Upper Cretaceous secession of the study area is broken into (half) grabens by rift faults having roughly SW-NE and NW-SE trends. The extensional tectonic event, which caused formation of main (half) grabens, lasted since the Albian to Cenomanian or Santonian. Most of the rift faults of the BS were partly inverted during compression in the Middle Eocene and Late Miocene. The Ukrainian BS and CM represent an inverted Early Cretaceous rift system of highly variable geometry. The tectonic units of BS originated due to the intracontinental rifting. The Western and Eastern Black Sea Basins did not develop as oceanic or suboceanic basins as suggested by up-to-date geodynamic models. The Andrusov Ridge presents the Cretaceous rift (half) graben inverted and folded by compression in the Middle Eocene. The folds of CM formed in the Eocene and Late Miocene phases of regional compression by reverse movements along planes of rift faults. The current conceptions on evolution of the BS region should be reconsidered.

Combined database of earthquakes and tidal forces from the Moon and the Sun
Authors A.M. Kazantsev and L.V. KazantsevaSummaryAn approach to search for the connection of tidal forces from the Moon and the Sun with earthquakes is proposed. The earthquake database of the European-Mediterranean Seismological Center CSEM/EMSC is used (http://www.emsc-csem.org/Earthquake/world). The database contains information on earthquakes with magnitudes above 2 numbers since October 2004. By mid-March 2017, there were more than 320,000 recorded events in the database with such data: time point, epicenter coordinates, depth of hypocenter and magnitude.
To search for such connections, we plan to supplement the CSEM/EMSC earthquake database for each given moment and hypocenter with the tidal forces from the Moon and the Sun, the resultant forces, their directions, and some other values. The combined database of earthquakes and tidal forces from the Moon and the Sun will be recorded in text format and displayed for universal access.

The calculation of infiltration of the surface waters into soils on the territory of the Mezhyhiria tract on the right bank of the Kiev water reservoir
Authors Yu. V. Heruk, E.D. Kuzmenko, A.P. Nikitash and Ye. O. YakovlevSummaryThe research of the moistening of the subsurface soils under the intensive technogenic burden of the territory of the Mezhygorie tract on the right bank of the water reservoir of Kiev hydropower station was carried. During investigations, the technogenic component of subsurface water was reduced to units that are comparable with the amount of rainfall. As a result, we have the opportunity to use quantitative assessment of the balance of the natural and technogenic components of rainfall and surface waters as a basis for calculating the infiltration. The ratio of natural and technogenic water estimated that is equal to one to two. All components of infiltration were quantified and authors proved more than a threefold increase of infiltration into the aquifer at the expense of amount of technogenic waters, followed by unloading the aquifer on the slope of the water reservoir.

About a temporal relation between precipitation and groundwater levels on the right bank of the Kiev hydroelectric reservoir
Authors Yu. V. Heruk, E.D. Kuzmenko, L.I. Davybida, Ye. O. Yakovlev and A. P. NikitashSummaryThis publication presents results of investigation of the hydrogeological and geotechnical conditions within natural boundary Mezhyhirya which located on the right bank of the Kyiv hydroelectric reservoir on the Dnieper River. The power sources of the aquifers were identified. It was established that the shaping of the groundwater levels regime was carried out by the rainfall infiltration in the aquifer directly on the site, the infiltration of precipitation in the adjacent areas and further transit on the territory, the transit from the reservoir of the Kiev pumped-storage. It was proved that in the annual cycle the levels regime and the variability of rainfall have a close correlation with the time lags of levels in the magnitude of 1.2 to 4 months. Dependencies of the levels time lags in relation to precipitations were found. The dependencies are shown in the reduction of time lags approaching to the groundwater discharge zone and in a direct correlation between the lags and altitudes of the levels in the same direction and, therefore, in an inverse correlation with the power of the aeration zone.

Oil and gas potential assessment of Siljan impact crater in Sweden by frequency-resonance method of remote sensing data processing
Authors S. Levashov, N. Yakymchuk, I. Korchagin and D. BozhezhaSummaryThe results of oil and gas prospects assessment of the entire Siljan crater and local exploration area within it are analyzed. A survey of these areas were carried out with a frequency-resonance technology of satellite images processing using for “direct” searching and prospecting of hydrocarbons (HC) accumulations. The investigation results are given by maps of maximum values of fluid pressure in the reservoir. This is, in fact, a complex parameter, whose value depends of the gas pressure, contained in the fluid or in free form in the reservoir, as well as of its amount, i.e. of the rock porosity. These zones deserve of detailed study and drilling. The resulting estimates of fluid pressure in the reservoirs indicate of their position at the top of the cross-section. The probability of commercial hydrocarbon accumulations discovery within the crater at depths over 800–1000 m is very low. However, the results of additional studies within one large anomaly have been shown the existence of more deep intervals for hydrocarbon accumulation searching in cross-section. In the case of their confirmation, this will be crucial for the operative assessment of hydrocarbon potential of deep horizons of the cross-section. From investigation results follow also that the drilled deep wells Gravberg-1 and Stenberg-1 are not optimally positioned (they are not within anomalous zones). Application of direct-prospecting technology of remote sensing data frequency-resonance processing will speed up and optimize the process of prospecting and exploration for commercial hydrocarbon accumulations in the Siljan impact craters area.

Study of acoustic emission of a terrigenous type collector fluid saturation sample under external acoustic influence
Authors G.V. Igolkina and V.V. DryaginSummaryThe parameters of acoustic emission of fluid saturated-sample of terrigenous reservoir type with external acoustic impact using the device of the core research for the conditions close to the reservoir are studied. It is registered and made a detailed analysis of the acoustic emission signals in the porous space of the core in dry and liquid saturated conditions of different types: water, kerosene, oil. Core, saturated by oil, have a maximum value of the accumulated signal and a correspondingly high velocity signal output, which has a pulse character. For the cores, saturated with water, can be seen a steady decline of the signal, and the acoustic emission signal dispersion for water saturating was at least 2–3 less than by oil saturating. It is detected the connection between the acoustic emission changes and saturation of the reservoir, which occur after the external acoustic impact on it, which is reflected in an increase of acoustic emission level in the oil-saturated reservoir and decrease in water-saturated reservoir.

Geological background and search criteria of industrial oil and gas accumulations discovery within Burgas prospecting area in Bulgaria
Authors A. Samsonov, S. Levashov, N. Yakymchuk, I. Korchagin and D. BozhezhaSummaryThe paper presents and analyzes the results of the of mobile and direct-prospecting methods application on a Burgas prospecting area in Bulgaria. Prospecting studies within area were conducted with using the mobile technology of remote sensing data frequency-resonance processing and interpretation and the ground-based geoelectric methods of forming the short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS).
Two local anomalous zones (Western and Eastern) of the “oil” and “gas” type have been detected within the prospecting area. Within the contours of these anomalous zones the deposits of oil and gas in industrial (commercial) volume can be found in the cross-section. Discovered by direct prospecting methods anomalous zones can be considered as projections into the surface of hydrocarbon accumulations contours in the cross-section. This information may be used for an approximate estimate of hydrocarbon resources within the surveyed areas and structures. For the Western anomalous zones approximate estimates of probable resources of oil and gas have been calculated by received data of studies. Given that the prospecting and exploration of commercial oil and gas accumulations on the onshore and the development of discovered resources is significantly cheaper than within offshore, the detected and mapped anomalous zones deserve of a detailed studying by geophysical methods and drilling.
