Assessment of Environmental, Ecological and Human Risks of Drilling Waste Management in the Tundra Ecosystems of the Yamalo-Nenets Autonomous District

The relevance of environmental protection measures in the Yamalo-Nenets Autonomous District (YNAD) is connected with both specific role of the region in ensuring the required level of hydrocarbon production and considerable vulnerability of the Arctic tundra ecosystems in the conditions of increasing anthropogenic pressure. Use of different drilling fluid compositions and the formation of drilling waste are inseparable from the drilling procedure. Presence of technological challenges facing the industry has a major influence on expansion of the range of chemical compounds used for preparation of drilling fluids, and, accordingly, present in drilling waste.
