Long-term oil and gas project implementation periods in the Arctic zone create risks of natural and technogenic emergencies. These are caused by changes in the Earth's climate system, as well as equipment wear and tear and reduced corrosion resistance. This paper focuses on developing methods for assessing geoecological risks caused by the long-term operation of oil and gas facilities in the Arctic zone. Particular attention is given to localization to de-vision of geodynamically active disturbance zones. Remote methods for their of zone devision and certification are considered.

Open-pit mining is one of the most environmentally unfavorable methods of mineral extraction, accompanied by significant anthropogenic impact and a high risk of ground surface deformations. Under conditions of climate warming and permafrost distribution in the Arctic, such processes are particularly relevant. This study analyzes ground displacement and moisture dynamics at the Irelyakh dredging site using Sentinel-1 and Landsat satellite data. The developed approach makes it possible to assess the condition of dams, monitor their stability, and predict potential failures using satellite information and geographic information technologies.
