An overview is given of various currently applied monitoring techniques for CO2 storage. Techniques are subdivided in correspondence to their applicability for monitoring three distinct realms. These are: - the atmosphere and the near- surface; - the overburden (including faults and wells); - the reservoir with its seals. Another subdivision can be made with respect to time, i.e. first monitoring during the injection and storage process and subsequently monitoring for the long term (after abandonment of the field). In this perspective, the importance of characterisation and monitoring before injection is addressed.
