“…During the past 4 years, results have been reported from several laboratory studies of the mineralogical changes that occur when cement is reacted with CO 2 -rich aqueous fluids and scCO 2 (Bachu and Bennion 2009;BarletGouédard et al 2007BarletGouédard et al , 2009Brunet et al 2009;Centeno et al 2005Centeno et al , 2007Centeno et al , 2009Jacquemet et al 2005Jacquemet et al , 2008Kunieda et al 2008;Kutchko et al 2007Kutchko et al , 2008Kutchko et al , 2009Regnault et al 2009;Rimmelé et al 2008;Scherer et al 2005;Wigand et al 2009). Some of these studies have included testing of the cement durability and degradation from exposure to CO 2 -H 2 S mixtures (Centeno et al 2005(Centeno et al , 2007(Centeno et al , 2009Jacquemet et al 2005Jacquemet et al , 2008.

SummaryPermanent storage of anthropogenic CO 2 in deep geologic formations is being considered as a means to reduce the concentration of atmospheric CO 2 and thus its contribution to global climate change. To assure safe and effective geologic sequestration, numerous studies have been completed regarding the extent to which CO 2 migrates within geologic formations, and what physical and geochemical changes occur in these formations when CO 2 is injected. Sophisticated, computerized reservoir simulations are used as part of field site and laboratory CO 2 sequestration studies. These simulations use coupled multiphase flow-reactive chemical transport models and/or standalone (i.e., no coupled fluid transport) geochemical models to calculate gas solubility, aqueous complexation, reduction/oxidation (redox), and/or mineral solubility reactions related to CO 2 injection and sequestration.Thermodynamic data are critical inputs to modeling geochemical processes. The adequacy of thermodynamic data for carbonate compounds has been identified as an important data requirement for the successful application of these geochemical reaction models to CO 2 sequestration. Therefore, a review was completed of thermodynamic data for CO 2 gas and carbonate aqueous species and minerals present in published data compilations and databases used in geochemical reaction models. Published studies that describe mineralogical analyses from CO 2 sequestration field and natural analogue sites and laboratory studies were also reviewed to identify specific carbonate minerals that are important to CO 2 sequestration reactions and therefore require thermodynamic data.The results of the literature review (Section 5.0) indicate that an extensive thermodynamic database exists for CO 2 and CH 4 gases, carbonate aqueous species, and carbonate minerals. Values of ∆ f G 298° and/or log K r,298° are available for essentially all of these compounds. However, log K r,T° or heat capacity values at temperatures above 298 K exist for less than approximately one-third of these compounds. Because the temperatures of host formations that will be used for CO 2 injection and sequestration will be at temperatures in the range of 50ºC to 100ºC or greater, the lack of high-temperature thermodynamic values for key carbonate compounds, especially minerals, will impact the accuracy of some modeling calculations.In comparison to the available thermodynamic data for carbonate minerals, only a small number of carbonate minerals have been described in published studies as actually being present in the host rock formations at CO 2 injection test sites or natural analogue sites, reaction products of CO 2 injection/ intrusion into a host formation, or as mineral reactants or products of laboratory CO 2 fluid-rock and -mineral experiments. Except for a few carbonate solid-solution minerals (ferroan and magnesian carbonates and ferroan dolomite), thermodynamic data are available for the pure carbonate minerals identified in these natural analogue site and fluid-rock and -mineral...

RésuméUn modèle de transport réactif est proposé pour simuler la réactivité des matériaux à base de ciment en contact avec une saumure saturée en CO 2 et/ou le CO 2 supercritique (CO 2 sc) dans les conditions de stockage géologique du CO 2 . Un code a été développé pour résoudre simultanément le transport et la chimie par une approche globale couplée, compte tenu de l'effet de la température et de la pression.La variabilité des propriétés du CO 2 sc avec la pression et la température, telles que la solubilité dans l'eau, la densité et la viscosité sont pris en compte. On suppose que tous les processus chimiques sont en équilibre thermodynamique. Les réactions de dissolution et de précipitation de la portlandite (CH) et Ce modèle est en mesure de simuler les processus de carbonatation des matériaux à base de ciment, dans des conditions à la fois saturés et insaturés, dans une large plage de concentration de CO 2 , de température et de pression. Plusieurs expériences, rapportées dans la littérature, sont simulées en utilisant divers types de conditions aux limites: (i) solutions saturées ou non en CO 2 et carbonate de calcium, (ii) gas supercritique de CO 2 . Les prédictions sont comparées avec les observations expérimentales. Certains II phénomènes observés expérimentalement peuvent être également expliqués par le modèle. Mots-clés:Carbonatation, CO 2 supercritique, Transports, Ciment, C-S-H, Décalcification, Pression, Température, Stockage du CO 2 . AbstractA reactive transport model is proposed to simulate the reactivity of cement based material in contact with CO 2 -saturated brine and supercritical CO 2 (scCO 2 ) under CO 2 geological storage conditions. This code is developed to solve simultaneously transport and chemistry by a global coupled approach, considering the effect of temperature and pressure.The variability of scCO 2 properties with pressure and temperature, such as solubility in water, density and viscosity are taken into account. It is assumed that all chemical processes are in thermodynamical equilibrium. Dissolution and precipitation reactions for portlandite (CH) and calcite (CC) are described by mass action laws and threshold of ion activity products in order to account for complete dissolved minerals. A chemical kinetics for the dissolution and precipitation of CH and CC is introduced to facilitate numerical convergence. One properly chosen variable is able to capture the precipitation and dissolution of the relevant phase. A generalization of the mass action law is developed and applied to calcium silicate hydrates (C-S-H) to take into account the continuous variation (decrease) of the Ca/Si ratio during the dissolution reaction of C-S-H. The changes in porosity and microstructure induced by the precipitation and dissolution reactions are also taken into account.Couplings between transport equations and chemical reactions are treated thanks to five mass balance equations written for each atom (Ca, Si, C, K, Cl) as well as one equation for charge balance and one for the total mass.

“…Although a similar carbonation process is mentioned, the cement sample demonstrates that at least in one location, Portland cement has retained its structural integrity after 30 years in near-CO 2 -reservoir environment (Carey et al, 2006). Furthermore, recent experimental studies on the interfaces cement/formation and cement/casing were led and showed that similar chemical reactions are involved (Jacquemet et al, 2005;Duguid et al, 2006).…”

Résumé -Technologies de puits pour le stockage géologique du CO 2 : ciment résistant au CO 2 -Le stockage souterrain du CO 2 est actuellement considéré comme la voie la plus efficace pour une séquestration sure et à faible coût. Cette nouvelle application exige une étanchéité du puits à très long terme. La rupture de la gaine de ciment dans l'intervalle entre le cuvelage et la formation géologique peut créer des chemins préférentiels favorisant la fuite du CO 2 vers la surface avec des vitesses probablement supérieures à celles pouvant être provoquées par les fuites au travers des formations géologiques. Il en résultera une perte économique, une réduction de l'efficacité du stockage de CO 2 et la remise en cause du champ pour le stockage de CO 2 . Ce risque potentiel de fuites soulève des questions quant à la bonne isolation du puits à long terme et à la durabilité du ciment hydraté utilisé pour isoler l'annulaire entre les intervalles de production et d'injection dans les puits de CO 2 . Nous proposons une nouvelle procédure expérimentale et une méthodologie pour étudier la réactivité des systèmes CO 2 -Eau-Ciment en simulant les interactions du ciment pris avec le CO 2 injecté à l'état supercritique dans des conditions de fond de puits. Les conditions utilisées pour ces expériences sont de 90ºC et 280 bars. L'évolution des propriétés mécaniques et physico-chimiques du ciment Portland est mesurée dans le temps sur une période maximale de six mois. Les résultats sont comparés à ceux obtenus par une étude similaire sur un nouveau ciment résistant au CO 2 , la comparaison étant prometteuse pour ce nouveau matériau. Abstract
