The level of complexity and comprehensiveness will vary according to the use to which it will be put. In any specific case, however, the purpose of conducting an assessment may vary from simple calculations to test initial ideas for storage concepts, to support for an application for regulatory approval requiring detailed, site-specific performance assessment against relevant criteria. The general purpose of an assessment of geological CO2 storage is to determine the performance of the storage system.
