Abstract. The current situation in the world’s energy balance is that hydrocarbon energy continues to occupy a major niche. As a result, oil and gas companies continue to increase the volume of oil and gas exploration and production operations, thereby increasing the share of recoverable hydrocarbon reserves. In parallel to these processes, the global energy industry is trying to create a balance in the consumption of «dirty» and generation of «clean» energy. In other words, society is striving for sustainable development, in which environmental and social aspects are particularly important. Consequently, energy producers with high emissions and waste generation have obligations to minimize and prevent them. For example, drilling oil and gas wells generates wastes that are difficult to utilize due to their multi-component composition. To date, the utilization of such wastes, otherwise known as drill cuttings, is carried out by methods aimed at achieving economic efficiency and reducing the burden on the environment. This paper considers methods of utilization of drilling waste generated as a result of operational activities of oil and gas companies, in particular, during drilling. The purpose of the work is to determine the possible economic and environmental effects from the application of drilling waste utilization technologies. The object of the study is drilling wastes of oil and gas companies. The authors analyzed the works of domestic and foreign researchers in the field of drilling waste management. On the basis of literature review the reasons of technological difficulties of waste utilization are described. The advantages and disadvantages of drilling cuttings utilization methods, as well as economic and environmental prerequisites for their effective utilization are revealed.
