Energy is considered one of the key factors of human development, providing the necessary conditions for its existence and vital activity, the degree of material and economic well-being. The leading position among fuel and energy resources at the present time belongs to oil, as the most productive energy carrier. Overcoming the current economic crisis is associated with an increase in global demand for black gold and an increase in the pace of its production. The involvement of ever-increasing volumes of hydrocarbon resources in production circulation reduces their reserves and leads to the need for exploration and development of ever-new deposits. It is a well-known fact that since the peak of the formation of geological exploration in the 60s of the XX century to the present period, the number of discovered deposits on the onshore part is steadily decreasing, and the number of developments on the shelf is increasing. The offshore zone of the Caspian Sea is a very promising region for the production of hydrocarbons, where the richest deposits have been explored and exploited. However, oil production at sea is much more difficult, more expensive than on land and involves significant environmental risk. The most important tool of environmental protection activities used almost all over the world is an environmental assessment based on a comprehensive analysis of the most likely impact of the proposed activity on the environment. This procedure is carried out in order to establish the compliance of the planned economic activity with environmental requirements and to determine the admissibility of the implementation of the object and to prevent possible negative impacts of this activity on the environment and the associated social, economic, environmental and other consequences. The constant increase in demand for hydrocarbon resources and their involvement in economic turnover, as well as the reduction of reserves and environmental risks associated with their production and exploitation of deposits have determined the relevance of this article. The purpose of the work was to identify the features of the current ecological state of the marine environment in the water area of the planned development of hydrocarbon deposits.
