Abstract: Due to the discovery and development of oil and gas fields in the North of Western Siberia and in other regions of the Russian Federation, intensive construction and operation of infield facilities is underway in the Northern regions. Difficulties of economic development of these areas significantly increase the amount of capital investments in construction, so, an indispensable condition for the development of new territories is modern scientific and technical preparation, the most important element of which is hydrogeological, engineering-geocryological and ecological research. Of considerable importance in this is creation of a new scientific area-ecological geocryology which will study emerging problems.
