Evaluation and Characterization of a Potential CO2 Storage Site in the South Adriatic Offshore

International audienceThe Southern Adriatic Sea is one of the five prospective areas for CO2 storage beingevaluated under the FP7 European Sitechar project. The potential reservoir identified in theinvestigated area is represented by a carbonate formation (Scaglia Formation – Late Cretaceous).This paper shows the site characterization applied to one of the structures identified in the carbonatestorage system of the South Adriatic offshore. The interpretation and analysis of seismic andborehole data allowed the construction of a 3D geological static model on both regional and localscales. Dynamic modeling was applied, adopting a sensitivity approach ( i.e. fault transmissivity,petrophysical properties of the caprock and reservoir, and different stress regimes). Coupled fluidflow and geomechanical simulation was applied to investigate the potential risk of leakage inducedby mechanical solicitation on the faults occurring in the investigated area
