The aim of the study was to determine the level of geological environment contamination as a result of long-term use of an oil field in the Perm Region, which is located in complex geological conditions. During the study areal electrical exploration was carried out with the help of the vertical electrical sounding (VES) method, 15 geotechnical boreholes were drilled and geoenvironmental soil testing was carried layer by layer. Interpretation of geophysical data revealed the presence of hydrocarbon and chloride components in soils and karst rock mass. The researchers have found petropollutted grotto and the water source exit with traces of oil, they mark their association with the locations of oil wells. Most likely sources of oil pollution of the geological environment are oil wells. Thus, in the mining and geological conditions, due to the development of karst processes, long-term operation of the oil field in the presence of incidents and emergencies leads to the formation of hydrocarbon contamination in the subsurface with the subsequent distribution into ground- and surface water.

This research is devoted to the experimental study of hydrocarbon pollution spread in different kinds of subsoils. Hydrocarbon stress was created of the engine oil, subsoils are presented in small and medium size sand, silty fine clay, in air-dry state and of different humidity. It was founded that the depth of hydrocarbon contamination distribution in soils is determined by lithology. For all soils the maximum contamination occurs in the first day, and the maximum rate of penetration of hydrocarbons is observed in the first 4 hours after the emergency oil spill on the earth's surface. Clay with humidity above the limit rolling prevent the penetration of hydrocarbons in the soil and can act as oil resistance. Source
