ASSESSMENT AND PROTECTION OF GEOENVIRONMENT COMPONENTS FROM IMPACTS PRODUCED BY TECHNOGENOUS HYDROCARBON DEPOSITS

The article presents the results of studies of technogenous hydrocarbon deposits - Light Non-Aqueous Phase Liquid (LNAPL) bodies in technonatural systems. The specific feature of these bodies is their location in the geological environment beneath operating and abandoned oil industry enterprises. Enterprises are the sources of hydrocarbons in the geological environment. Light non-aqueous phase liquid bodies are interpreted as complex, dynamic, multicomponent systems, which are subject to the influence of flooding and low-water phenomena in the nearby surface water bodies. Based on the study of archive data and the results of field survey of these objects, the integrated system has been developed for assessing the status of technonatural systems containing LNAPL bodies. It is based on the suggested criteria, and includes geometric, technological, geoecological, resource-economic and inertial-oscillatory groups. The scheme of carrying out a complex of works, including research, assessment, modeling, and liquidation of LNAPL bodies is proposed. This scheme takes into account the LNAPL dual nature: on the one hand, LNAPL body contaminate the environment, on the other hand, produce secondary hydrocarbon resources. The proposed integrated assessment system permits us to determine the current state of LNAPL bodies as a part of technonatural systems, to select and justify technological solutions for their liquidation and remediation of contaminated sites.
