The article presents the approach of Rosneft Oil Company to the selection and prioritization of facilities for the development of oil and gas fields located in the Arctic zone of Russia for the implementation of geotechnical monitoring. The relevance of the geotechnical monitoring development and implementation as a mandatory set is shown. Measures on the basis of the geotechnical monitoring make it is possible to ensure the safe operation of assets throughout their life cycle. Implemented approaches allow Rosneft Oil Company to put into practice a comprehensive assessment and prioritization of the potential consequences of accidents and incidents at hazardous production facilities, taking into account gradation by engineering and geological conditions, hazard class of structures, the principle of permafrost using, as well as the severity of consequences for people, the environment and damage to production. New approaches have been proposed to develop regulatory requirements for the introduction of geotechnical monitoring at existing facilities, because for a significant number of previously built facilities, the need for geotechnical monitoring was not regulated despite the influence of the global warming trend on the state of permafrost. The classification of Rosneft Group companies by the level of geotechnical monitoring organization has allowed to unify approaches to the development of technical, organizational competencies and the development of monitoring culture. Taking into account the proposed methodology, a geotechnical monitoring development plan was formed at Rosneft Oil Company, which included the development of criteria, the ranking of facilities, the analysis of the current status of the monitoring organization, the inventory of networks, the monitoring organization at high-priority facilities, the formation of monitoring schedules, the development of the Company's competencies and regulatory framework
