Overview of assessment of leakage detection and intervention scenarios for CO2 sequestration

CO2 storage security, monitoring and verification are of utmost importance for the long term implementation of CCS for the purpose of reducing global emissions of carbon dioxide. There are several mechanisms which have the possibility of compromising the security of super critical CO2 stored in deep saline aquifers or depleted oil and gas reservoirs. Of particular interest is the risk of leakage via faults and fractures which could provide fluid migration pathways from the storage reservoir to overlying aquifers or even to the earth’s surface. A focus on the investigation and development of methods for dealing with CO2 leakage is urgently needed for industry and regulators alike to be prepared for managing such events should they arise. A quick response to unforeseen events will reduce the risks and costs associated with them, and increase public confidence in CCS as a climate mitigation option. This chapter introduces and summarizes conclusions from the three chapters that follow dealing with detection and remediation.
