Abstract

The long-term activity of oil refineries has led to the formation of man-made hydrocarbon deposits under their sites. The deposit is a lenticular formation, elongated in plan for several kilometers towards the groundwater discharge zone, penetrating into the geo-environment up to the first aquifer. The reserves of technogenic deposits can be commensurate with traditional natural deposits. On the one hand, technogenic deposits are a formation containing a mixture of raw materials and processed products of various fractions and commercial quality hydrocarbons. In this case, the content is extracted from the rocks with the help of pumping equipment of a network of production wells, separated from the water component and transferred for use or processing as a secondary material resource. On the other hand, a field containing sub-grade hydrocarbons is a significant water-oil emulsion. It is a constant source of negative impact on the environment and pollution of adjacent fragments of the geological environment. The use of a water-based layer containing hydrocarbons in concentrations insufficient for resource use is its treatment as contaminated wastewater. Purification of the water-emulsion phase from residual hydrocarbons is lengthy and extremely costly and requires new modular treatment facilities at the location of the hydrocarbon deposit or reserve capacities at existing plants.
