Optimization of plugging design for well abandonment- Risk management of long-term well integrity

摘要: Abstract A part of MOVECBM EU project is dedicated at evaluating the long-term wellbore integrity on basis a risk perspective. This i mplies, among others, to optimize plugging strategy, in order mitigate associated CO 2 migration inside well during abandonment phase (i.e. post injection). The role containment well’s components has be ensured for hundreds years, despite degradation mechanisms ageing) that affect their properties. To leakages, probabilistic study was casing corrosion support design strategy and its optimization. achieved with calculations based in-situ data taking into account uncertainties. Results this enable get objective criteria decision process efficient MS-3 (vs. perspective).
