The assessment of environmental risks at oil and gas production facilities is one of the most important and relevant areas. Essentially, the results of the current assessment procedure are in most cases divorced from the real situation that is taking shape in the territory of mining operations. The main issue is the lack of a methodology that would combine an assessment of each component of the environment. The aim of this work is to justify and develop an integrated methodology for assessing environmental risks. For this, we considered the main types of environmental impacts of oil and gas production companies, and from existing methods for assessing environmental risks we selected those able to take into account the largest range of impacts. Using the resulting set of methods for assessing environmental risks, we conducted a study of the environmental condition at the oil and gas fields in the Lena-Tunguska oil and gas province, namely, the Yarakta, Iktekh, and Markovo fields. As a result, the environmental risk identified at these facilities corresponded to the “medium” level. As result, at these facilities during the risk management procedure it is necessary to implement additional measures aimed at minimizing the negative impact on the environment.

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.

Due to modern conditions and trends in production activities, fire risk assessment at the facilities of the coal and oil and gas industries has become of great importance in determining the conditions for ensuring fire safety. The article describes the specifics of the main causes of emergencies associated with fires in the extraction of fuel and energy resources and the application of risk assessment methods. We identified a number of illogical axioms, as a result of which the calculated fire risk values are determined non-objectively and can lead to low fire protection at the facility and even to human losses. The aim of the article is to improve the fire safety assessment applied to the facilities of the coal and oil and gas industries. In connection with the identified deficiencies in the calculation of fire risk according to regulations, it was proposed to make changes to the “Methods for Determining the Calculated Values of Fire Risk at Production Facilities”, which will make it possible to more accurately determine the value of fire risk and reduce the likelihood of emergencies.
