The area of Surgutneftegas activity for a long time was limited to the right bank of the Middle Ob River. Over a 50-year period of oil and gas production, hydrocarbon reserves have declined significantly. To maintain the current level of oil production, the company is doing a lot of work to replenish the resource base, including exploration in new territories. Among these territories is the south of the Nefteyugansk region of the Khanty-Mansiysk autonomous district – Yugra. Currently, the Nefteyugansk region in terms of density of licensed sites ranks first in the Khanty-Mansiysk autonomous district – Yugra. For a long time, the south and southeast of the region remained poorly studied, but licenses for the search and exploration of hydrocarbons were also issued to this territory. At several licensed sites, exploration work is carried out by Surgutneftegas. Moreover, the environmental impact is even at the stage of exploration. It can be 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 licensed 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 include the determination of both the background state and the current one, which allows determining the degree and consequences of the impact of oil and gas production on the environment.
