120 years and hundreds of kilometres of gas and oil pipelines with unsatisfactory operational reliability (Fig. 1) (Glushkevych (2014)).

An important group of indicators that affect the environmental safety of a man-made object (in our case, an oil and gas well) are indicators of the quality of technical means (Kiran et al. (2017), Yatsyshyn (2018)). The process of construction of oil and gas wells and subsequent stages of the life cycle is accompanied by a large number of different technical means, the quality, and compliance of which provides a high probability of trouble-free operation. Additional risks of failures of responsible oil and gas equipment are due to the significant operation life for more than 30 years (Fig. 2) (Ingraffea et al. (2014), Yavorsky et al. (2016, 2017), Chudyk et al. (2019)). Properties that determine the quality of products can be characterized by: quality parameters (quantitative characteristics of quality); quality characteristics (qualitative characteristics), which are combined into quality indicators (Bernardo et al. (2009)). The quality indicators of technical means that affect the environmental effects of the construction of oil and gas wells include the following: • constructive indicators; • reliability indicators; • indicators of economic use of raw materials, fuel, and energy; • indicators of manufacturability; • indicators of transportability; • environmental indicators; • safety indicators. The above indicators have both a direct impact and an indirect impact on the formation of not only the risk of dangerous emergencies but also other undesirable environmental effects. The analysis of the quality indicators of technical means in the construction of oil and gas wells indicates a close relationship between environmental and economic effects, which necessitates the consideration of these concepts in the complex. Thus, the search for a balance between making a profit and preserving the environment is one of the decisive factors in the successful greening of enterprises around the world. In line with these challenges, global companies
