Abstract

A potential threat of pollution of hydrolithosphere with petroleum and its products due to accidental and technological leaks on a certain industrial object has been analyzed. The author's method of mathematical modelling is described that allows to perform an adequate dynamic modelling of a petroleum products lens in an aquifer. Execution of the resulting model allows to forecast behavior of petroleum products in the conditions of a real geological and hydro-geological cross-section.

Highlights

Experience of the geoecological research in the last decades shows that the pollution of geological environment with petroleum and its products is very common–is comprises one third of all instances of pollution
The surface of groundwater near oil terminals is reported to have a layer of flowing petroleum products with capacity up to 2.0 metres, and the load of the petroleum products in vadose zone is 2-5% of soil mass
The lens of free petroleum products is connected to the territory of the oil terminal at the northern side (Fig. 2)

Summary

Introduction

Experience of the geoecological research in the last decades shows that the pollution of geological environment with petroleum and its products is very common–is comprises one third of all instances of pollution. Almost all existing petroleum industry enterprises (upstream, midstream and downstream sectors) pollute hydrolithosphere. Many source areas of such pollution are classified as ecological disaster zones [1, 2]. Due to accidental and technological leaks of petroleum products, Pyatigorsk and Tuapse oil terminals have become massive sources of pollution of vadose zones and groundwater. Annual leakages of petroleum products with volume ranging from 300 to 500 tonnes have formed pollution hotbeds of 1km (Tuapse) and up to 5km (Pyatigorsk), which cover residential areas of the cities. The surface of groundwater near oil terminals is reported to have a layer of flowing petroleum products with capacity up to 2.0 metres, and the load of the petroleum products in vadose zone is 2-5% of soil mass
