One of the main factors of complicated oil extraction on the territory of the main business activity site of Surgutneftegas JSC - Middle Ob is high water-bearing nature of the region, about 40%. On the territory of Russinskoye oil field the amount of water is even greater – about 70%, 30% is accounted for woodlans including bottom lands. The hydrocarbons extraction influences on all the components of the nature within the territory of the oil field. This could be observed through the changes of the original landscapes geochemical status of the environment. Regular monitoring fixes these changes.
In this article the data of presence of different hydrocarbons, carbonic acids, biogenic substances, heavy metals exceeding the threshold available concentration in all streamflows of Rusinskoye oil field is presented. This is the feature not only of the Rusinskoye oil field, but of the whole Khanty-Mansiysk Autonomous District-Ugra. This is proved by the annual researches made on these territories.
The same situation is with the bed deposits and with the soils. The threshold available concentration of pollution is not exceeded in atmospheric air only.
The presence of different chemical elements in surface waters has not only the anthropogenic nature but the environmental too. Modern methods of researches allow observing the anthropogenic and natural pollution. The fact that gas-oil extraction greatly changes the environment is commonly recognized. The plants spend lots of money for different nature-protecting measures on each oil field. Their effectiveness is proved by the regular ecological monitor results made on all the stages of oil field developing process.
