Assessment of environmental damage from oil sludge to land resources in the Irkutsk Region

Abstract

In Russia, the problem of sustainable development is most acute and representative. For the vast territories and rich natural subsoil resources, the environmental issue becomes the most acute. In Russia, from an environmental point of view, there are many territories of concern which make it clear that theoretical issues gain practical importance. The Central Siberian Plateau with its large reserves of raw hydrocarbons - the Lena-Tunguska oil and gas province with a total area of about 2.8 million km2 - is a region of intensive oil and gas production. The amount of ecosystem transformations has no analogues in Russia; all transformations were formed in a short period of time (30-50 years). To maintain this industry, linear and non-linear structures were built, which transformed the landscape and territories not only superficially: the exploration and well construction transformed the geology of the region. This article addressed the damage caused to the soils of the Irkutsk Region in oil and gas production by the three most promising fields: the Yarakta, Markovo and Dulisma fields. The calculation was made in accordance with the methodology for calculating the amount of damage caused to the soil as an object of environmental protection. The calculated damage without taking into account possible emergencies at oil and gas production facilities amounted to almost 100 million rubles.
