The results of interpretation the data of electric and pulsed neutron-neutron logging methods for the study of low-resistivity reservoirs, example is terrigenous sediments of the Dnieper-Donets basin.
Authors K. Ruchko and V.M. KurganskySummaryResearch of untraditional hydrocarbon reservoirs are particularly important in due to the need to expand production of hydrocarbons in Ukraine. These species include terrigenous sediments of low-resistivity . They related to significant deposits of oil and gas, but in many cases they are skipped because his electrical resistance coincide with a similar electrical parameter saturated layers. Low values of electrical resistivity of reservoir rocks complicate the assessment of character of saturation of low-resistivity terrigenous reservoirs and determining the position of fluid contacts, effective capacity, coefficients of hydrocarbon saturation. Therefore, at the study of reservoirs special interest consists in the research of the physical nature of anomalous conductivity, which is necessary for interpreting the results of electric logging wells. In this paper the processing and geological interpretation data of logging well in low-resistance hydrocarbon wells was performed using the “GeoPoisk.”

Notices on the methodic of the digital gravity databases foundation in Ukraine
More LessSummaryThere is postulated a renaissance of gravity surveys due to improvement on the accuracy of mea¬sure¬me¬nts and to the development of software for the processing and interpretation of gravimetry data. An ade¬quate requirements to the modern geophysical practice are formulated on the optimal accuracy for the means of interpretation of the potential fields data. Main trends of reinterpretation of data being sto¬red in the archives are pointed out with the aim of creation a unified digital framework for the geo¬phy¬sical databases. The main problems there are the creation of high-speed solutions for digitization of maps and the creation of digital databases on modern OS platforms. A series of separate branches are generalized, justifying the creation of a new methodology for gravity (and other) databases for the territory of Ukraine. In particular, it is suggested as follows: for a database engine to use a Postgre¬SQL; for a method of digitizing paper maps – by A.I. Yakimchik technique (as an input for digitizing is not contour maps, but the measurements log (map of the field points being converted into the digital grid map of gravity anomalies); for a new standard of preprocessing of gravity data – the technique by Bychkov S.G. (needs to develop the own parameters for calculating of gravity amendments); to add to the standard set of maps for the interpretation the maps of the absolute values of the gravity field, and for this reason to change the Instructions on gravity surveys on 1980; to combine together in a united public interface the complementary data on the areas of research; to change not the secrecy bar on gravity data, but the concept of intellectual property: to replace competition within the access to measurements data by the competition on the results of data interpretation.

Quantitative regional landslide hazard prediction using GIS within the Southern coast of Crimea
Authors K.Y. Boiko and O.Y. KoshliakovSummaryLandslides on the Southern coast of Crimea have been an object of long-term researches and explorations. However, the existing range of techniques to identify landslide formation factors and landslide predicting is losing its relevance today. This is related to the state of funding of the monitoring work that provides filling of the database required for predicting as well as to the change in research area - from grand landslide systems to shallow landslides in deluvial-eluvial deposits. The introduction and substantiation of the relevant method of regional predicting of landslides distribution and activation in surface deposits is important to overcome these problems. We propose to analyze landslide hazard areas based on using regional predicting method with GIS. As the latter, SINMAP tool (or method) was selected - stability index mapping technique. Using the slope stability factor as a criterion for determining the landslide hazard and geological-hydrogeological approach to analyze landslide formation factors, this technique provides an opportunity to perform quantitative, i.e. deterministic spatial and temporal predicting of landslide hazard areas. The south-western landslide sub-area was selected as a test site being characterized by the highest percentage of damage by landslide forms and numbering around 600 landslides within it, most of which are specifically shallow-lying landslides the activation or formation of which is caused by joint or separate effect of man-caused load (in the form of slope undercutting, overload or overwatering), erosion and weather conditions (in the form of excessive precipitation).

Abnormal cases of winter invading of cold masses on the territory of Ukraine
By A. SavchenkoSummaryUsing the regional reanalysis of the atmospheric circulation for the period of 1958 – 2007 the quantitative estimates of sensible and latent heat fluxes on the surface of the Black Sea in winter, as well as the statistical characteristics of the total heat flux values were obtained. The synoptic composites of anomaly corresponding to the extreme cooling of the Black Sea were built. It was found that the extreme cooling occurs when the anticyclone with the center located to the northwest of the Black Sea is formed. Established cooling is happening in the emerging field of anticyclonic center, located northwest of the Black Sea. Thus synoptic conditions were considered for extreme lowering surface temperature for Ukraine and shows the changes of meteorological characteristics in the European region through reanalyses ERA-40 / Interim. It will be shown that cooling of Ukraine and sea surface of north-western part of the Black Sea is under increasing pressure in the Baltic Sea and the reduction in the district of the Caucasus Mountains, and creating between these two areas strong cold air flow, which causes a reduction in surface temperature in the territory of Ukraine to 8 ° C from average in winter.

On the filtering of magnetic targets within the deep by the analytical continuation in framework of equivalent sources
Authors O. Chornaya and Yu. DubovenkoSummaryBased on the analysis of magnetic data for a Pineview park of 30×80 m, a calculation is carried out in upper space for magnetic anomalies with the aim of their archaeological interpretation. An analytical conti¬nu¬ation procedure allowed us to divide the anomalies by the sources deep. A field extraction from the sources in an equivalent layer by means of calculation of the residual field from the anomalous borders of sources allowed to define the contours of magnetic anomalies. The additional calculation of horizontal gradient of magnetic induction allowed us to specify the classification of local anomalies by the amplitude. The results of interpretation have qualitative character, but allowed to localize the location of excavations.

Authors V. Lyalko, O. Azimov and Y. YakovlevSummaryСonsiders the relevance of the application of modern remote aerospace and hydrogeological methods in solving the environmental security of the hydrosphere when the shale gas will be production in Ukraine. Place your examples of the pilot implementation of these methods within the Bilyajivka site of the Dnieper-Donets Depression which is adjacent to the Yuzivka area. On basis of accounting the hydrogeologic filtrational parameters and the results of thematic decoding of remote sensing data we performed the tentative expert appraisal of the temporal rates the upward migration of pollutions from a fracturing zone to the ground water-bearing horizon when in use the shale gas probable production. The region of the Bilyajivka-400 borehole was considered as an example. As a result we established that the achievement time of the migrating pollutions from the fracturing zone to the ground water-bearing horizon level will amount to 50÷5 years. It will depend on a possible variability the active porosity value of the joint fissure that predicted in the region of mentioned borehole via remote sensing decoding data.

Crust thermobaric anomalies of rocks lowered density and enhanceable porosity
By V. KorchinSummaryPhysical characteristics of different types of crystalline (igneous and metamorphic) rocks largely depend on their fractures and porosity, state of intergrain boundaries. Interest to researches of interstitial space considerably grew in connection with the study of migration of gas-liquid fractions, in particular hydrocarbons, in crystalline rocks on the different depths of lithosphere. All of gamut of appropriate and casual reasons, which influence on formation of pores and microfractures, to expose it is practically impossible. However, a tendency is exposed, that at petrographically similar groups of rocks the increase of porosity and microfractures conduces to reduce of elastic waves propagation velocity in them. In the offered work on the basis of study of connection of interstitial space with the longitudinal waves propagation velocity at high pressures and temperatures in the Ukrainian shield granites samples an attempt more fully to describe a change porosity and fractures of rocks depending on Р and Т influence of different depths is carried out, to explain some crust anomalies of rocks unpacking, which can be conductors of migration and localization of deep origin hydrocarbons.
