Site screening represents the coarsest scale of assessment with the least site specific details. Depending on the size of area in question, regional sedimentary Basins assessment, trans-border Basins or smaller parts of Sedimentary basins are taken into consideration in the following sequence (Chadwick et al., 20062006 - R. A. Chadwick, O. Eiken, P. Williamson, G. WilliamsGeophysical monitoring of the CO2 plume at Sleipner, North Sea: an outline reviewsee more; Kaldi and Gibson-Poole, 20082008 - J. G. Kaldi and C. M.

- Identify sedimentary basins or smaller areas (sandstoneSand that has turned into a rock due to geological processes and to lesser extent carbonateNatural minerals (e.g. calcite, dolomite, siderite, limestone) composed of various anions bonded to a CO32- cation sediments in the case of storage(CO2Carbon dioxide) A process for retaining captured CO2Carbon dioxide, so that it does not reach the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%) in saline aquifers, coal basins)
- Review the characteristics of sedimentary basins or smaller areas (e.g. tectonic setting, faulting, hydrodynamic regimes, extent and thickness of perspective sedimentary formations)
- Qualitative and (if possible) quantitative ranking of sedimentary basins or smaller areas in order of suitability.
