Abstract
A comprehensive geo-ecological survey of the territory of an oil field located in a karst region was carried out. The study of an oilfield technogenesis on the territory of a karst region includes detection of the features of mechanogenesis, hydrocarbon flows, salt migration in soils and watercourses, and the spread of atmospheric pollutants. To determine the severity of these man-made processes in space, remote sensing methods were used. The potential capacity for hydrocarbon accumulation in the karst massif of the Arapov Klyuch ravine can be up to 350.239 tons. Geochemical methods and bioindication established that bituminization covered kars cavities, springs, streams of the upper reaches of the Yasyl River, as well as bottom sediments and soils. Technogenic halogenesis is expressed in an increase in the concentration of chlorides and hydrocarbonates near the technical objects of the oil field, and also halophilic microorganisms were found. The geoecological map reflects the patterns of technogenic processes in the karst region during oil production. The developed methodological complex of geoecological research can be used in the study of other karst regions.
