The article deals with the issue of selecting treatment technologies at different stages of the drilling waste life cycle: from waste generation to environmental assimilation or use in economic activity as waste-produced materials. The existence of alternative technological solutions for drilling waste recycling or landfilling and a wide variety of waste generation conditions highlights the relevance of adequate comparative assessment of technologies and selection of the best option for a particular oil field. Choice of waste management technologies should be based on reliable data; therefore, it has to include information and analysis of drilling waste treatment technologies, legal restrictions, climatic and geological conditions of the territory, as well as information on field development program, existing and planned technologies and infrastructure. The proposed approach to the choice of technologies includes a feasibility analysis of specific techniques for certain fields, and a comparative technological and economic assessment for implementing appropriate technologies. The analysis puts forward a list of technologies that comply with legislation, meet the limitations of application, and other mandatory criteria. At the same time, technologies are excluded from further consideration that, despite possible advantages over other options (for example, low costs, high productivity, etc.), cannot be implemented in this field in principle (for example, they have a temperature limitation, at the field no peat available, etc.). The economical assessment stage compares technical and economic indicators of different waste management options and selects the best technology. Thus, the proposed systematic approach to the integrated assessment of technologies by technological, environmental, economic, and other criteria generates a list of technologies, recommended for use at a specific facility, and ranks them.
