Monitoring and Verification of CO2 underground

A wide array of monitoring technologies has been used by the oil and gas industry to track fluid movement in the subsurface. These techniques are readily adaptable to CO2 storage to monitor the behavior of CO2 underground. For example, seismic surveying provides an image of the subsurface, often allowing the behavior of stored CO2 to be mapped and predicted. Other monitoring technologies include down-hole and surface CO2 sensors. New technologies such as satellite imaging, which can detect movements of less than 1mm in the Earth's surface are also being developed.
