For the long time all the activities of Surgutneftegas PJSC in Khanty-Mansiysk autonomous district – Yugra were located in northern part of the Surgut region on the right bank of the Ob River. Over a 50-year period of oil and gas production, hydrocarbon reserves have declined significantly. To keep the level of oil extraction the company performs different measures, including geological prospecting work. The south of Surgut district is one of such territories.
Respect for the environment is the basic principle of sustainable development of Surgutneftegas PJSC. To determine the background and current state of surface water, including bottom sediments, soil, and atmospheric air, Surgutneftegas PJSC carries out monitoring studies in accordance with the current legislation of the Russian Federation. They acquire particular relevance at the initial stage, when the territory of the deposits is not yet subjected to anthropogenic impact and it is possible to fix the background state of natural environments. This is important from the point of view that not only the oil industry contributes to the formation of the geochemical situation in the territory, but above all, nature itself.
It is known that at the stage of prospecting and exploration, environmental impact occurs, accompanied by a change in the appearance of landscapes and the initial geochemical environment of natural environments. On some components of nature (soil and vegetation cover) the effect is point-like and is limited to construction sites, on others (aquatic environment) it is somewhat larger due to the nature of the natural component. When working in subsoil areas, in accordance with the licensing agreement on the conditions for the use of subsoil, Surgutneftegas PJSC conducts studies to determine the environmental impact through environmental monitoring of natural environments. The research results are included in the determination of both the background and the current state, which will allow us to further evaluate the degree and consequences of the impact of oil and gas production on the environment.
