Abstract

Carbon sequestration technologies are to reduce the carbon dioxide (CO2)emissions and in turn, to mitigate global climate change without adversely influencing energy use or hindering economic growth. However, various requirements must be met before these technologies will be accepted by the public for wide-scale implementation. Comprehensive long-term monitoring programs are inevitable to reduce corresponding risks. Such programs include both theoretical and applied scientific studies related to the characterization of the sub-surface and to understand the processes associated with the carbon sequestration technologies. Geophysical monitoring is an essential tool for the reservoir characterization and for providing information on the injection related processes. The seismic method has proven to be a suitable technique for qualitative and quantitative monitoring CO2. The mass estimation of the injected CO2 visible in seismic data is important for assessing storage efficiency.
