Framework Methodology for Long-Term Assessment of the Fate of CO 2 in the Weyburn Field

This chapter presents a framework methodology for long-term assessment of the fate of CO 2 in the IEA Weyburn CO 2 Monitoring and Storage Project. It involves the evaluation of the potential for CO 2 to migrate away from the reservoir along both natural and artificial (wellbore) pathways to the environment, and relies on the technical input from a number of disciplines. These disciplines include geology and hydrogeology, geochemistry, geomechanics, reservoir modeling and wellbore technology. The chapter describes the framework used for carrying out the long-term assessment, thus ensuring that work being carried out by other research workers is properly integrated into the CO 2 migration modeling. The chapter focuses on the various components of systems analysis, including features, events and processes (FEP) and their incorporation into scenario development.
