“…The CO 2 arrival in the observation well was detected by the downhole measurements of the amount and nature of the dissolved gases in the fluid samples by GMS (Gas Membrane Sensor) and the increase of the well head pressure (Giese et al, 2009). The CO 2 arrival resulted in a significant decrease in pH and the number of bacteria (Fig.…”

“…The CO 2 arrival in the observation well 1 (Ktzi 200) was detected by the downhole measurements of the amount and nature of the dissolved gases in the fluid samples. Notably, detailed physical, geochemical and microbiological monitoring was performed in all three wells (Giese et al, 2009). However, this study concentrates on the results obtained from the observation well 1 (Ktzi 200), where it was possible to monitor the effects of the CO 2 exposure during the five months.…”

This study reveals the first analyses of the composition and activity of the microbial community of a saline CO 2 storage aquifer. Microbial monitoring during CO 2 injection has been reported. By using Fluorescence in situ Hybridisation (FISH), we have shown that the microbial community was strongly influenced by the CO 2 injection. Before CO 2 arrival, up to 6x10 6 cells ml -1 were detected by DAPI-staining at a depth of 647 m below the surface. The microbial community was dominated by the domain Bacteria that represented approximately 60 to 90 % of the total cell number, with Proteobacteria and Firmicutes as the most abundant phyla comprising up to 47 % and 45 % of the entire population, respectively. Both the total cell counts as well as the counts of the specific physiological groups revealed quantitative and qualitative changes after CO 2 arrival. Our study revealed temporal shifts in the microbial community from chemoorganotrophic to chemolithotrophic populations, as evidenced by the outcompetition of sulphate-reducing bacteria by methanogenic archaea. In addition, an enhanced activity of the microbial population after five months CO 2 storage indicated that the bacterial community was able to adapt to the extreme conditions of the deep biosphere and to the extreme changes of these atypical conditions.

“…For monitoring of CO 2 , the injection well and the two observation wells were equipped with geophysical sensors including e.g. a fiber-optic-sensor cable loop for Distributed Temperature Sensing (DTS; all wells) and a Vertical Electrical Resistivity Array (VERA) consisting of fifteen toroidal steel electrodes per well and 15-line surface connection cables (Prevedel et al, 2009;Giese et al, 2009). In recent studies, Electrical Resistivity Tomography (ERT) based on cross-hole measurements has been evaluated as a suitable method to detect the resistivity changes caused by CO 2 injection and migration in geological reservoirs (Ramirez et al, 2003;Christensen et al, 2006).…”

Re´sume´-Caracte´risation pe´trophysique inte´gre´e pour le stockage de CO 2 : application au site de Ketzin -La simulation et le suivi d'un stockage de CO 2 requiert des donne´es pe´trophysiques spe´cifiques. Nous pre´sentons un ensemble d'expe´riences applicables a`tout stockage et a`toute couverture, fournissant des donne´es pour des simulations nume´riques re´alistes du potentiel de stockage et de l'injection. Ces expe´riences sont inte´gre´es avec les donne´es diagraphiques pour l'estimation de la porosite´, la saturation irre´ductible, la pression capillaire et la perme´abiliteŕ elative de l'eau en drainage, la saturation en gaz re´siduelle, les relations re´sistivite´-saturation et les proprie´te´s de transport de la couverture (perme´abilite´et diffusivite´). Le cas conside´re´est l'aquife`re salin du Trias dans le contexte du projet CO 2 SINK, le premier site expe´rimental de stockage en Allemagne situe´pre`s de Ketzin.Nous avons utilise´des me´thodes de mesure ne´cessitant des dure´es raisonnables tout en restant repre´sentatives des processus in situ. Pour le transport diphasique, nous avons utilise´la centrifugation. Pour la re´sistivite´, nous avons utilise´une me´thode rapide « Fast Resistivity Index Measurement » (FRIM) en drainage et imbibition, en condition ambiante et en condition de stockage. Pour la caracte´risation de la couverture, nous avons utilise´une technique rapide RMN (Re´sonance Magne´tique Nucle´aire) utilisant le deute´rium comme traceur pour la mesure de diffusion et une me´thode stationnaire innovante pour la mesure de perme´abilite´. La pression d'entre´e a e´galement e´te´e´value´e. Les diagraphies RMN et de re´sistivite´ont e´galement e´te´utilise´es pour estimer de manie`re continue la saturation irre´ductible et juger de la repre´sentativite´des e´chantillons analyse´s au laboratoire.Pour le site de Ketzin, la zone de stockage est un gre`s argileux d'origine fluviatile localement tre`s cimente´d'une porosite´d'environ 30 % et d'une perme´abilite´variant de 100 a`300 mD. Deux zones se distinguent par des saturations irre´ductibles variant de 15 a`35 %. La courbe de perme´abilite´relative a`l'eau pre´sente une forte pente et sugge`re qu'une saturation infe´rieure a5 0 % n'est pas atteignable en pratique. L'exposant de saturation de l'indice de re´sistivite´est de 1,7, plus faible que la valeur standard de 2. La couverture a une perme´abilite´de 27 nD, une porosite´de 15 % et une diffusivite´de 0,8 9 10 À9 m 2 /s. Abstract -Advanced and Integrated Petrophysical Characterization for CO 2 Storage: Application to the Ketzin Site -Reservoir simulations and monitoring of CO 2 storage require specific petrophysical data. We show a workflow that can be applied to saline aquifers and caprocks in order to provide the minimum data set for realistic estimations of storage potential and perform pertinent simulations of CO 2 injection. The presented series of experiments are fully integrated with quantitative log data analysis to estimate porosity, irreducible saturation, drainage capillar...

“…This distributed temperature sensing system was applied to the CO2SINK project in Germany where CO2 was injected into a saline aquifer with an anticlinal structure [Forster, 2006]. Although the definite cause observed in temperature signal is still being investigated, the distributed temperature sensing system successfully measured the largest temperature increase (Δ25 °C) close to the injection wellhead during the injection period [Giese et al, 2009 ] while the temperature increase within the injection zone was about Δ5-10°C. In summary, CO 2 injection into the Arbuckle formation are expected to disturb the temperature regimes in the target formations, and such temperature changes could be detected by installation of temperature sensors in injection and observation wells.…”
