Assessment of environmental damage to atmospheric air during development of oil and gas fields

At present, new tasks arise for the oil and gas producing industry in the Russian Federation. This is due to the geopolitical need to develop new oil and gas producing regions, in addition to the existing fields, in the coming years. These regions include, first of all, the Lena-Tunguska province with the most promising Dulisma, Yarakta, and Iktekh fields. The impact of extractive industry facilities on the environment is manifested both at the construction stage and at the stage of their exploitation. This makes it necessary to study geoecological risks for various facilities of the extractive industry. The authors studied the ecological situation in the production activity area of the fields and established the main environmental consequences of gas and oil production and their negative impact on the environment. Having measured the factors of the production environment, we established that the fields pollute the atmosphere mostly with emissions of hazardous substances, such as carbon monoxide, nitrogen and natural gas. The authors carried out an estimation of the economic damage to atmospheric air during the development of the fields. As a result, it was found that the Yarakta field causes the greatest economic damage to the atmospheric air. (paper)
