Confining Properties of Carbonated Dogger Caprocks (Parisian Basin) for CO2Storage Purpose

Abstract: Résumé -Propriétés de confinement des couvertures du Dogger carbonaté (Bassin de Paris) dans l'optique du stockage de CO 2 -Le projet Géocarbone-Intégrité, financé par l'Agence Nationale de la Recherche (ANR) de 2006 à 2008, vise à développer les connaissances et les techniques nécessaires à la prévision de l'efficacité et la sécurité du confinement sur le long terme des stockages géologiques de CO 2 . La première tâche a été de caractériser à l'échelle pétrographique, les faciès carbonatés du sommet du Dogger… Show more

“…One possible reason is that it has a much higher proportion of large diameter pores, as revealed by NMR tests (cf. [8]), which may be a reason why anion exclusion would be minimal. Another interesting point is the value of the Rε factor for the bicarbonate ion that is significantly larger than the NMR or mercury porosity.…”

“…8, upper right). The capillary entry pressure for CO 2 /brine has been evaluated in laboratory tests on rock samples of various types of caprock (Hildenbrand et al 2004;Chadwick et al 2008;Carles et al 2010). Data indicates capillary entry pressure for CO 2 is generally less than that of methane and can range from less than 0.1 up to 10 MPa.…”

“…For petrographical and petrophysical properties, advanced techniques are necessary. For example, low permeability measurements are difficult and time-consuming to perform using standard steady-state techniques, and other techniques must be used [7]. Similarly, standard thin sections for petrographical observations give limited information and Scanning Electron Microscopy (SEM) must be used.…”
