Abstract
The abundance and diversity of aggressive microflora, sampled in the oil-polluted territory of Ust-Balykskoye oilfield near the destroyed transmission towers and taking an active part in corrosion of oilfield equipment and concrete hydraulic structures, have been investigated. The investigations have shown that on the surface of the destroyed towers, in the polluted water and bottom sediments the number of aggressive microorganisms is by 3-5 orders of magnitude higher as compared to the samples from non-polluted area, where transmission towers were in operating condition. Using GIS-technologies we have made a map of Ust-Balykskoye oilfield.
