Le sud de la Mer Adriatique est l’une des cinq zones potentielles pour le stockage du CO2 évaluées dans le cadre du projet FP7 européen SiteChar. Le réservoir potentiel identifié dans la zone étudiée est constitué d’une formation de carbonate (Formation Scaglia – Crétacé supérieur). Cet article présente la caractérisation de site de stockage de CO2 appliquée à l’une des structures identifiées dans les formations carbonatées du sud de la Mer Adriatique. L’interprétation et l’analyse des données sismiques et des données de forage ont permis la construction d’un modèle statique géologique 3D à des échelles régionale et locale. Une modélisation dynamique a été effectuée, intégrant une analyse de sensibilité (sur la transmittivité des failles, les propriétés pétro-physiques des roches couverture et réservoir, et différents régimes de contraintes). Une simulation couplée géomécanique et d’écoulement de fluide a été menée pour étudier le risque potentiel de fuite provoqué par les contraintes mécaniques sur les failles de la zone étudiée.

Abstract
The Southern Adriatic Sea is one of the five prospective areas for CO2 storage being evaluated under the FP7 European Sitechar project. The potential reservoir identified in the investigated 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 carbonate storage system of the South Adriatic offshore. The interpretation and analysis of seismic and borehole data allowed the construction of a 3D geological static model on both regional and local scales. Dynamic modeling was applied, adopting a sensitivity approach (i.e. fault transmissivity, petrophysical properties of the caprock and reservoir, and different stress regimes). Coupled fluid flow and geomechanical simulation was applied to investigate the potential risk of leakage induced by mechanical solicitation on the faults occurring in the investigated areaFile | Dimensione | Formato | |
