CO2sc is planned to be injected in 2013 at the Hontomín site (NE Spain) as a part of the EC-funded OXYCFB300 project. Approximately 100,000 tons of CO2 is going to be injected in a saline reservoir (1500 m depth) hosted by Lower Jurassic limestones and sealed by Lower Cretaceous clay formations. One of the aims of the project is to demonstrate that CO2 storage is safe, and there is a control on the evaluation and fate of the CO2 injected, and on the potential environmental effects. Such a control requires a detailed monitoring study of the CO2 fluxes at the soil-atmosphere interface before, during and after the injection operations. The soil CO2 flux has been measured using an accumulation chamber. Seven surveys have been carried out from November 2009 to summer 2011, the work is focused on the determination of a baseline flux of CO2 and its seasonal variation, as the baseline is essential in order to detect potential leakage during injection and post injection. The measured values were low (from 5 to 13 g·m?2·day?1). Few outliers were identified for higher flows, mostly located in the vicinity of H-2 well. In the south of the surveyed area, geophysical data suggest the existence of deep fault connected to shallow stratigraphic horizons; there, gas flow was as low as those areas without fractures. In conclusion, the baseline of soil-atmosphere CO2 flux in the injection site shows that natural fluxes are very low. Therefore, potential leakage is expected to be detected.
