Introduction. The paper considers the issue of estimation of disordered areas as a result of construction and anthropogenic activities and suggests strategies for solving this problem by the example of the Samara region. Materials and methods. The article applies the generally accepted methods and research conducted by employees of Samara State Technical University. The sources of initial data are reports of state authorities. The subjects of the study are engineering-geological environmental elements, industrial facilities, polluting components and surface and Groundwater bodies. Results. The paper proposes a ranking-system for estimation of disorder areas and classification by areas of economic activity. The article provides the classification of the impact of technological losses of enterprises, the activity of which leads to the disruption of the geological environment. A resource and ecological approach for technogenic deposits of various substances and a strategy for their use and subsequent environmental restoration are proposed. The research presents the results of technogenic deposit 3D simulation as well as approaches to their interpretation. Conclusions. The developed approach and methodological basis for the analysis of the geological system, including the technogenic lens allow evaluating, analyzing, and predicting the migration of human-made lenses formed as a result of construction and economic activity. A resource-based and ecological approach was used for the simultaneous collection of pollutant fluids and the rehabilitation of the geological environment. The article recommends to use 3D digital simulation methods to increase the efficiency of research and predict the number of substances in the depths. The methods apply to human-made deposits, subject to the determination of the ambiance filtration characteristics by water and fluid. It is proposed to use biodegradable surfactants as a method of geological environment rehabilitation. This choice is stipulated by the fact that surfactants allow “washing” the rocks without increasing the burden on the environment. An alternative method is proposed for predicting fluid migration due to the description of the geosystem as a system of forced oscillations. The method allows predicting the periods of the most efficient oil production and designated engineering protection methods.
