The results of the analysis of geoecological problems of territories of long-term hydrocarbon production are presented. Based on the analysis of ground-based and remote studies, the possibilities of space data were determined during the eco-monitoring of hydrocarbon deposits. A methodological and technological scheme for assessing the risks of harming the environment is proposed. The list of tasks that can be solved using Earth remote sensing data:- control of environmental pollution by hydrocarbons (oil, gas) at different stages of the functioning of the oil and gas complex - from the search and exploitation of deposits, to the transportation, storage and processing of petroleum products;- flooding and flooding of territories of oil production by underground waters;- identification, mapping, field studies, discontinuous violations of various ranks, are ways of migration of oil and gas in the upper layers of the earth's crust;- identification and mapping of technogenic sources of gas contamination of the surface layer of the atmosphere, namely:- non-geometrical wells, oil and gas pipelines;- buried under modern sediments, pit-well houses, mines.Satellite monitoring consists of 4 stages. At the first, preliminary stage, objects of remote monitoring are determined, a base of satellite and thematic data is formed, the foundations of a future thematic GIS are laid. At the second stage, the actual detection (decryption) of objects and territories polluted with hydrocarbons is carried out. At the next, third stage, a set of field work is carried out in order to validate the research methodology and verify the data obtained using ground-based measurements.At the fourth, final stage, based on an analysis of all the information received, an assessment of the risks of dangerous situations is carried out and their possible consequences are predicted.The possibilities of assessing the risks of dangerous situations in areas of long-term hydrocarbon production according to remote sensing data are considered. A review of hazardous situations resulting from hydrocarbon production in the city of Borislav is given .; recommendations are proposed to reduce the risk of their occurrence.

Introduction. At the current stage of information technology development, methods for remote sensing have been increasingly used for mineral exploration.Problem Statement. Significant capital intensity of geological works for intrusive bodies search when the crystalline basement is overlapped by a thin sedimentary cover requires the implementation of advanced methods that, on the one hand, allow reducing the costs of exploration and, on the other hand, enable increasing theaccuracy of objects identification.Purpose. The development of methodological framework for the application of remote sensing data to identify prospective areas in search of buried intrusive bodies.Materials and Methods. Medium (Landsat, Sentinel) and high (WorldView) resolution optical satellite imagery data in the thermal infrared and visible ranges of the electromagnetic radiation spectrum; radar satellite data (SRTM), multispectral aerial survey data obtained by unmanned aerial vehicles; methods for structuralinterpretation, digital terrain model analysis, results of field thermometry have been used in this research.Results. A few prospective sites for the search for buried intrusions within the Hubkivska and AnastasivskoBolyarska squares of the Novohrad-Volynskyi block of the Ukrainian Shield, regardless of the geophysical data, have been identified. These objects were later confirmed by detailed geomagnetic surveying and drilling. Withinthe detected thermal anomalies, several small (60—120 m long and 30—50 m wide) dikes have been detected. Four of the 5 wells drilled have confirmed the presence of dike bodies, and 1 well enters the fracture zone. In other areas, where detailed geophysical survey was carried out within the detected thermal anomalies, new dike bodieshave been discovered.Conclusions. The developed technique may be used as an additional tool in geological prospecting.
