Abstract

The corrective measures investigated in the MiReCOL project broadly fall under three categories: techniques relevant to controlling CO2 migration within the reservoir, techniques relevant to fault-related migration and techniques relevant to wellbore-related leakage mitigation. The overall performance characterisation was based on five dimensions, namely: likelihood of success, spatial extent, longevity, response speed, and cost efficiency. The probability plots and spider chart visualisation tools developed are considered to be particularly useful in facilitating the general comparison between leakage remediation techniques, or choosing a portfolio of remediation techniques, for operators dealing with a situation where CO2 storage security may be compromised in the field. Research in MiReCOL recognised that the assessment lacks value for consequence reduction, unless it is complemented with an effective framework which allows for the optimal allocation of resources for remediation technology implementation, considering the uncertainty with regards to their outcome, i.e. success or failure.
