Rapid expansion of geological storage of CO2, at the giga-tonne scale, is required to mitigate CO2 emissions into the atmosphere. Potential storage basins need to be characterized rapidly to determine the best sites for injection and long-term security. The hydrocarbon industry has developed the common risk segment mapping approach over many years, for assessing exploration potential based on static reservoir properties (geological seals, permeability, porosity etc). More recently this has also been applied to evaluating storage potential for CCS by Bump et al. (2021).
