“…The third phase dealt with the estimation of theoretical capacity within each identified geological province. At present, various calculation methods have been proposed to know the storage capacity of a rock formation [22,10,23,20,24,25,2]. They have been applied to different country projects within their respective areas and still there is uncertainty.…”

“…In the case of a closed aquifer (a volume of water that can not exit the aquifer) basic physics indicate that the storage capacity is limited due to compressibility and pressure build up limitations [1,2]. In the pressure build up is evenly distributed throughout in a volume of water, the mass of CO 2 that can be stored is directly connected to the pressure build up:…”

“…This effect was modelled for a typical aquifer [2,20]: -local pressure increase to honour injectivity can reach 10 MPa for the aquifer studied; -average pressure increase to inject a given mass of CO 2 with time will be directly proportional to the size of the domain and Equation (2), ranging from 1 to 24 MPa in the case studied. These papers illustrate the fact that local pressure increase at wells to honour injectivity can be very high compared to typical geomechanical / capillary entry constraints, hence average pressure increase in the aquifer is much smaller than pressure increase at wells, and in the case of a closed aquifer it may not be technically feasible to increase the average aquifer pressure up to the maximum allowable increase while injecting with significant CO 2 rates.…”

“…As underlined in the 2005 IPCC Special Report on CO 2 Capture and Storage [3], implementation of CO 2 capture and geological storage at the scale needed to achieve a significant and meaningful reduction in CO 2 emissions requires knowledge of the available CO 2 storage capacity. CO 2 geological storage into deep saline aquifers is presented as an attractive solution due to a large potential CO 2 storage capacity.…”

Résumé -Avons-nous surestimé les capacités de stockage de CO 2 des aquifères salins ? -Au cours d'opérations à grande échelle de stockage géologique de CO 2 dans des aquifères salins, la pression des fluides dans les formations va augmenter, mais devra rester sous des limites définies par des contraintes d'intégrité des sites de stockage. La hausse de pression est la conséquence de deux effets distincts. Premièrement, la pression augmente localement autour des injecteurs de CO 2 pour permettre l'injection du CO 2 dans les nappes. Cet effet peut être contrôlé en ajoutant des injecteurs de CO 2 . Deuxièmement, la pression va augmenter à une échelle régionale, soit parce que l'aquifère est fermée, soit parce que le flux d'eau s'échappant de la zone pressurisée ne compense pas volumétriquement le CO 2 injecté. Ce second effet ne peut pas être maîtrisé en augmentant le nombre d'injecteurs. Dans la première section du papier, nous discutons sur des évaluations mondiales ou régionales de capacités de stockage du CO 2 en aquifère, tant du point de vue de la quantité que de l'efficacité de stockage. Ces capacités sont principalement basées sur une approche volumétrique : la capacité de stockage est la somme des volumes de CO 2 pouvant être stockés par différents processus de piégeage. Dans la seconde section, nous présentons les efficacités de stockage calculées par une approche en pression, telles qu'établies dans le rapport final du projet CO2STORE (Chadwick A. et al. (eds) (2008)

An analysis of the influence of injection well location on CO2 storage efficiency was carried out for three well-known geological structures (traps) in deep aquifers of the Lower Jurassic Polish Lowlands. Geological models of the structures were used to simulate CO2 injection at fifty different injection well locations. A computer simulation showed that the dynamic CO2 storage capacity varies depending on the injection well location. It was found that the CO2 storage efficiency for structures with good reservoir properties increases with increasing distance of the injection well from the top of the structure and with increasing depth difference to the top of the structure. The opposite is true for a structure with poor reservoir properties. As the quality of the petrophysical reservoir parameters (porosity and permeability) improves, the location of the injection well becomes more important when assessing the CO2 storage efficiency. Maps of dynamic CO2 storage capacity and CO2 storage efficiency are interesting tools to determine the best location of a carbon dioxide injection well in terms of gas storage capacity.
