Abstract
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.

The integrated methodology considered will allow comparing the environmental risks of different oil and gas production companies
Summary
The current global environmental situation leaves much to be desired. The constant uncontrolled use of natural goods does not allow the environment to restore the destroyed territories and to replenish the lost biological resources. Anthropogenic and technogenic loads have overpowered the ability of the environment to self-purify, which already leads to irreversible processes of degradation and pollution of existing natural environments At this stage of its development, humanity is not able to exist otherwise. The modern process of technological development contributes to even greater consumption of resources, the depletion of the subsoil, the divestment of animal habitats, which affects humans themselves [1]. One of such strategically important elements for the development of any country is the reserves of hydrocarbon resources, namely oil, gas and oil and gas condensates
