Influence estimation and soils protection at drilling explorative holes on oil and gas

The estimation of technogenic influence on soil mantle is given at drilling oil-and-gas holes on Left-bank gas condensate field deposit had on Leno-Angarsk plateau within the limits of Siberian platform. Factors of influence are considered, forecast of negative consequences is given, nature protection actions are offered. By criteria of stability and the importance of soils the ecological risk of technogenic influence is estimated and displayed on the map.
