Abstract
Russian legislation requires companies to carry out environmental site
investigations in all cases of civil or industrial projects. The investor or owner is
the responsible party in the case of any pollution. Information on air, water and
soils quality is the main result of environmental site investigations.
We carried out about 60 environmental site investigations of oilfields in the
Western Urals. Environmental site investigations usually include field survey,
biodiversity inventory, sampling of air, water and soils, radio-activity and noise
measuring, analysis of monitoring data, socio-economic data analysis. We have
never detected cases of air pollution, noise or radiation more than that which is
allowable. Most common problems include contamination of surface water at the
stage of borehole drilling, and contamination of subsurface water at a late stage
of oilfield exploitation. Soil and groundwater salt pollution takes place at many
local sites. Remains of soil damage and pollution incidents occur at many local
sites. Most incidents took place in 1970-80s, when exploitation started. Pipeline
accident rates depend on relief and surface deposits and are also related to oil
prices.
Keywords: oilfields, environmental site investigations, air pollution, surface
water, groundwater, soils.
1 Specific regional features
The regional specific features of the Western Urals are:
prevalence of hard mineable reserves of extra-heavy crude oil contained
in small oilfields of complex structure;
Keywords
