Abstract

The efficiency of subsurface resource development in the Arctic zone of the Russian Federation (AZ RF) is closely linked to the need to minimize technogenic risks, particularly those arising from the influence of space weather on navigation systems operating at high latitudes within the auroral oval. Previous studies have described the mechanisms and extent of space-weather effects on the increased measurement errors of magnetic inclinometers used in well geophysical surveys. Drawing on data from a reference magnetic station and an assessment of inclinometric measurement quality (i.e., the ratio of low-quality data to the total number of inclinometric surveys) for 2022–2024 from operating wells in the Russian Federation, this study provides a qualitative evaluation of the relative likelihood of disruptions to technological procedures caused by extreme additional errors of measuring instruments. To reduce technogenic risks during oil- and gas-well development in the AZ RF and on the continental shelf, a decision-support framework is proposed that integrates real-time geomagnetic conditions into geophysical survey processes. Statistical relationships are examined, observed deviations are assessed, and an approach to their interpretation is outlined.
