Well pads frozen foundations at the Yamburg field in a climate change

The results of long-term observation the foundations temperature regime and dangerous cryogenic processes development near exploited well pads on Yamburg field are presented. Temperature observations (1992-2020) includes data four pads. Influence natural anthropogenic factors permafrost was investigated. Based a great experience observations, thermoerosion gas were characterized. Some considered, where increasing riverbed ravine required anti-erosion measures. According to frozen increases by an average 0,039 °C per year. show absence pronounced technogenic increase in foundations, which Cenomanian produces. Taliks with radius 5-10 m around wells observed at Valanginian On slopes adjacent depressions, rocks is high, sandy soils dumps subject erosion. threatens eroded riversides, areas ice-wedge polygonal tundra.
