Carbon dioxide sequestration in geological reservoirs is being evaluated internationally as a viable means of long-term CO2 storage. The International Energy Agency Weyburn CO2 Monitoring and Storage Project is designed to investigate the technical and economic feasibility of CO2 storage in a partially depleted oil reservoir in conjunction with enhanced oil recovery operations. Two key elements of the project are (1) the establishment of a regional geoscience framework as a means for prediction of the long-term fate of injected CO2, and (2) development and application of geophysical/geochemical monitoring and verification methods to track the spread of CO2 within the reservoir. To date, 1.90 billion m3 of CO2 have been injected into the reservoir, the effects of which are imaged by the various monitoring methods.
