The relevance of the research is caused by the need to assess the existing engineering geological conditions, processes, and hazards, as well as the risks and impacts related to them with respect to the intended use of the site of the Beregovoe Field of Purovsky District, Ya maloNenets Autonomous Okrug. A necessary preliminary step in development of the project is the analysis of engineeringgeological data of the construction site. The main aim of the research is to create the engineeringgeological map of the deposit for assessing the situation and forecasting the changes engineering geological conditions according to the results of the performed geotechnical investigations. Objects of researches are surface features and subsurface earth materials for design and construction of the Beregovoe field exploration. Methods: the analysis of engineeringgeological surveys, detailed lithologicalgenetic analysis of the territory, taking into account the regularities of the spatial variability of the main indicators of engineeringgeological conditions (composition of soils, their temperature, distribution of permafrost and engineeringgeological processes). Results. The authors identified six types of areas: A (lakes and marshes); B (drained lake); C (riverside); D (hilly ridge); E (linear ridge) and F (manmade soils). The results of the field works and laboratory investigations of geotechnical properties of soils allowed detailing a preliminary assessment of the engineeringgeocryological conditions. The main part of the route passes through riparian areas С. The most unfavorable for construction of facilities and pipeline are terrain types: A (found locally in the lowlands, represented by marshes with a capacity of peat to 2,2 m) and B (has wide distribution, represented by wetlands, folded clay soils with no surface runoff). The types D and E are not met on the route. We recommend placing the linear structures of pipelines on welldrained upland sites spread thawed soils.
