The extraction of hydrocarbons and their transportation from the fields is accompanied by the impact on all components of the natural environment. This impact is manifested both in a change in the external appearance of the surrounding landscapes and in the initial geochemical setting. At the same time, the strength of the impact and its consequences largely depend on the natural features of the area. The Middle Ob region, where most of the hydrocarbons of Surgutneftegas PJSC are produced, is characterized by a high degree of swampiness and lagging (more than 50%). However, within this territory there is an even lower and humid place, where the proportion of wetlands exceeds 80 and even 90%. This area was called the Surgut lowland, or Surgut marshlands. In such extremely difficult conditions there are many developed objects, including the Konitlor group of fields. The extraction of hydrocarbons in the swampy and lakeside areas places higher demands on the subsoil user to prevent environmental pollution. Owing to the observance of industrial and environmental safety requirements, competent organization of production, applied environmental protection measures, in the Konitlor group of fields, despite the emergencies, made it possible to prevent environmental pollution. This is confirmed not only by the company's monitoring studies, but also by remote sensing of the territory of the Khanty-Mansiysk Autonomous District - Yugra, which is carried out by the Department of Subsoil Use and Natural Resources of the autonomous district. At the same time, the most effective tool that can be used to assess the current state of natural environments and to determine the consequences of the impact of oil and gas production on the environment are monitoring studies. In Surgutneftegas PJSC, they are carried out at all fields and subsoil areas in accordance with the license agreement on the terms of subsoil use.
