Lightweight cement mixtures with high technological properties based on the standard well cement Portland cement ПЦТІ-100 and building cements ПЦІ-500-Н, ШПЦ Ш/А-400 with a light impurity-acid fly ash of thermal power stations were developed and investigated. The minimum density of cement mortars based on the developed mixtures is, respectively, 1 460–1 530 and 1 580–1 650 kg/m3, while ensuring the high quality of other technological properties of cement mortar and stone. The development and selection of optimal recipes for new lightweight cement mixtures has been carried out. The results of the work are of practical use in cementing oil and gas wells in complex mining and geological conditions in geological exploration areas and industrial hydrocarbon fields.

Geologic prospecting works (GPW) as a process of geological subsoil study with the use of a complex of special works and investigations lead to information acquisition on different geological objects, that is a powerful basis for creation of favorable investment development due to the systematized disclosure of information as regards prospective territories for the projects for forecast and search, estimating, prospecting and extracting works. The purpose of work is an analysis of the features of geological information arrangement during the economic-geological evaluation of mineral reserves and resources in Ukraine; a characteristic (classification) of types of geological information acquired at different stages of geological and feasibility studies (EGE-3, EGE-2, EGE-1); determination of geological information reliability and quality according to a stage of works. As a result, all geological works lead to acquisition of information on different geological objects that can be subdivided into two main categories – primary and secondary one. The methods for determination of the cost of geological information by the results obtained at any stage of works on the geological subsoil study have been presented. The cost of geological information is determined in view of the expenses given in the reports on geological subsoil study incurred during the performance of cameral works on a subsoil plot within which the cost of geological information is determined. When regulating the procedure for arrangement (granting in use and sale) of geological subsoil information, it is necessary to take into account legal features of information acquired for public and private funds. Despite the existence of legal norms in the field of subsoil use relating to geological subsoil study, today a stable mechanism of its legal support is under formation in the meanwhile. The legislation regulating the relations in the field of geological subsoil study requires improvement and agreement with other branches of legislation, stable and clear legal definitions and guarantees.

In order to detect technogenic violations, the hydrogeofiltration field of the aquifer closer to the land surface which is spreading within the site of metallurgical production of the Private Joint Stock Company “EVRAZ Dniprovskyi Metallurgical Plant” (PJSC “EVRAZ DMP”) was investigated. The data of the target analysis and the groundwater monitoring information (2010–2014) from the PJSC “EVRAZ DMP” local groundwater monitoring networks were used. A full-scale survey of observation wells and pilot filter work was carried out. Geoinformation approach was used for modeling the hydrogeofiltration field of the investigated aquifer. According to the results of geoinformation analysis, the presence of disturbances of level, balance and hydrogeotermal parameters of particular aquifer were observed. It was discovered the local “piezometric dome” perturbations of the water table and the stable abnormal groundwater temperature rise. Such changes indicate the presence of additional intensive anthropogenic sources of infiltration in local areas. The most relative level of water-ecological load is obtained the southwest zone of the industrial site with a borderline location. Therefore, the influence of the adjacent urbanized area on the deformation of the hydrogeofiltration field of the aquifer closer to the land surface within the studied area was not excluded. The preservation of the revealed tendencies of deformation of the hydrogeological conditions on the site might be produced a threat to safe operation of industrial structures as a result of intensification of the flooding process and derivatives – mechanical and chemical phenomena.

The paper presents the problem of collectors secondary porosity, which is the main component of the total effective porosity. Different aspects of this problem are considered: the origin and distribution of secondary porosity in the rock, the dependency between the structure of the pore space and its filtration properties, the formation of hydrocarbons deposits at great depths, the role of post-sedimentation processes in the formation of secondary porosity and fractures, as well as the issue of secondary porosity prediction and its role in prospecting secondary oil and gas reservoirs.

The article deals with the current state and problems of the main work directions in regional geological research of the Ukraine territory – the geological additional research of previously studied areas and creation of the State Geologiсal Map of 1:200 000 scale. The analysis of the new generation of State Geological Maps certifies that, compared to the first generation maps (1958–1974), they differ much informatively and scientifically substantiated and are the basic geological basis for planning and conducting of almost all types of geological exploration, geoengineering, geo-ecological, hydrogeological and mining works. The emphasis is placed on the fundamental foundations of scientific and methodological support of continuously developing and updating works including stratigraphic, tectonic, geophysical, petrological, petrographic, laboratory-analytical and geoinformation bases. It is shown that due to the miserable financing of works from the State budget, the current state of regional geological researches in Ukraine is critical.

The modern seismic activation of the main oil and gas areas of the Pre-Carpathian foredeep – Dolyna (1974–1976), Nadvirna (1996–2013) and Boryslav (2014–2017) was traced. The refinement of the location of the studied earthquakes courses is carried out on the regional travel time tables and the method of residuals minimizing. The directions of ruptures breaking in the foci of the stronger ones were studied, the ruptures lengths and other parameters of these courses were estimated. The spatial models of seismic activity of the main seismogenic structures in these areas have been constructed. It has been established that most of the earthquakes courses tend to transverse faults of the anti-Carpathian (northeastern) direction (in the zones of their intersection with the Precarpathian deep fault), which cross or limit the oil and gas structures, part of the courses tend to the ones available here thrusts and folds of different depth. Taking into account the long-lasting (starting from the 19th century) active production of oil and gas condensate here the local seismicity, obviously, is additionally technogenically provoked (induced).

The paper aims to examine the suitability of A. S. Balankin brittle fracture criterion in predicting the of large-scale coal and gas outbursts in underground coal mines under compression load. Formation of dissipative structures as cracks and clusters of local microcracking occurs under the influence of the rock pressure. The formation of microdefects in dissipative structures occurs mainly on local anisotropic inclusions. Mechanism of pre-outburst spalling of gas-saturated coal is analyzed. Destruction (primary outburst) occurs when the brittle fracture conditions are met. And also in the case of such a ratio of “coal seam thickness – the size of micro defects aggregations”, which provides reduction in coal strength to a minimum. Further destruction occurs by known scenario.
