Abstract & Overview
In the course of the three years work in the Arctic with ArcticDEM digital elevation models (DEM), the researchers have obtained fundamentally new results on the natural catastrophic transformations of the landscapes of the Yamal Peninsula in the process of powerful gas blowouts and explosions. They have proved the possibility of detecting gas-explosive objects and processes during regional 4D monitoring based on DEM processing, and in the course of the retrospective 4D monitoring, have identified a number of potential gas blowout objects. The authors have identified disadvantages and proved the need for further improvement of the ArcticDEM data. They have built 3D-models of the areas of catastrophic induced gas blowouts during the drilling of exploration wells in the Arctic, including the Kumzhinskoye field. Using an unmanned aerial vehicle (drone DJI Mavic Pro), the researchers carried out aerial photography and built 3D models of a number of gas blowout craters. For the first time in Yamal, they performed an underground aerial photography of the gas blowout crater space C17, indicating the existence of a gas-sat
