The regional data sets should be reviewed to evaluate the structural configuration and regional distribution of lithofacies. This is best done using a large 2-D seismic data set complemented with available well-log control and petrophysical data. The aim during this phase is to identify reservoir units with appropriate storage properties (such as adequate porosity for storage of substantial volumes of CO<sub>2</sub> and permeability for injectivity and subsequent dissemination into the pore system) overlain by suitably extensive and thick seals. | The regional data sets should be reviewed to evaluate the structural configuration and regional distribution of lithofacies.
