“…They were able to confirm that degradation of Portland cement is slow. Barlet-Gouédard et al [20] compared the behavior of a Portland cement with a Schlumberger CO 2 resistant cement (SCRC) with expanding agent under CO 2 geological storage environment (363 K, 28 MPa). They used brine containing 220 g/L NaCl.…”

“…They focused on the expansion of the cement because fractures caused by the expansion are one possible occurrence of leakages. The simulated injection scenario presented by Barlet-Gouédard et al [20] showed, that conventional Portland cement does not fulfill the requirements for the well integrity. Wigand et al [21] performed flow-through experiments which simulated the diffusion of brine (1.65 M) and scCO 2 from the interface between wellbore cement and caprock into a fracture-bearing Portland cement.…”

Abstract:The reaction of wollastonite (CaSiO 3 ) with CO 2 in the presence of aqueous solutions (H 2 O) and varied temperature conditions (296 K, 323 K, and 333 K) was investigated. The educts (CaSiO 3 ) and the products (CaCO 3 and SiO 2 ) were analyzed by scanning electron microscopy (SEM), powder X-ray diffraction (PXRD), and differential scanning calorimetry with thermogravimetry coupled with a mass spectrometer and infrared spectrometer (DSC-TG/MS/IR). The reaction rate increased significantly at higher temperatures and seemed less dependent on applied pressure. It could be shown that under the defined conditions wollastonite can be applied as a cementitious material for sealing wells considering CCS applications, because after 24 h the degree of conversion from CaSiO 3 to CaCO 3 at 333 K was very high (>90%). As anticipated, the most likely application of wollastonite as a cementitious material in CCS would be for sealing the well after injection of CO 2 in the reservoir.

“…Portlandite (Ca(OH) 2 ) and Calcium Silicate Hydrates (C-S-H) are the two primary mineral phases formed upon hydration [Taylor, 1997]. Numerous studies in recent years have addressed the interactions between cement and supercritical CO 2 or CO 2 -saturated formation water under conditions relevant to carbon sequestration [Bachu and Bennion, 2009;Barlet-Gouedard et al, 2006;Barlet-Gou edard et al, 2009;Brandvoll et al, 2009;Duguid and Scherer, 2010;Duguid et al, 2006;Kutchko et al, 2007Kutchko et al, , 2009Liteanu et al, 2009;Mason et al, Water Resources Research PUBLICATIONS 2013; Scherer et al, 2005;Condor and Asghari, 2009]. Many studies have focused on the reactive transport of CO 2 -rich fluid through cement-cement interface and the associated property evolution of cement fractures [Cao et al, 2013;Huerta et al, 2011;Huerta et al, 2013aHuerta et al, , 2013bLiteanu and Spiers, 2011;Luquot et al, 2013;Ozyurtkan and Radonjic, 2014;Walsh et al, 2012;Wenning et al, 2013;Yalcinkaya et al, 2011].…”

Fractures and defects in wellbore cement can lead to increased possibilities of CO 2 leakage from abandoned wells during geological carbon sequestration. To investigate the physicochemical response of defective wellbore cement to CO 2 -rich brine, we carried out a reactive flow-through experiment using an artificially fractured cement sample at a length of 224.8 mm. A brine solution with dissolved CO 2 at a pH of approximately 3.9 was injected through the sample at a constant rate of 0.0083 cm 3 /s. Surface optical profilometry analysis and 3-D X-ray microtomography imaging confirmed fracture closure and selfhealing behavior consistent with the measured permeability decrease. Visual inspection of the reacted fracture surface showed the development of reactive patterns mapping the flow velocity field inside the fracture, as well as restricted flow toward the sample outlet. The postexperiment permeability of the core sample was measured at half of its initial permeability. A reactive transport model was developed with parameters derived from the experiment to further examine property evolution of fractured cement under dynamic flow of CO 2 -rich brine. Sensitivity analysis showed that residence time and the size of initial fracture aperture are the key factors controlling the tendency to self-healing or fracture opening behavior and therefore determine the long-term integrity of the wellbore cement. Longer residence time and small apertures promote mineral precipitation, fracture closure, and therefore flow restriction. This work also suggests a narrow threshold separating the fracture opening and self-sealing behavior.

“…For this specific application, CO 2 is injected in the reservoir for short time-scales compared to the consideration of storing supercritical CO 2 in geological reservoirs for thousands years. During the last few years, much effort has been devoted to study the behavior of well cement for CO 2 storage application [4][5][6][7][8][9][10]. Indeed, cement that ensures isolation between the casing and the geological formation must be durable under the severe conditions considered in such application.…”

Résumé -Évolution des propriétés physiques et minéralogiques de deux roches réservoirs dans des conditions thermodynamiques correspondant à un stockage géologique de CO 2 à 3 km de profondeur -L'injection de dioxyde de carbone (CO 2 ) en sous-sol pour un stockage géologique à long terme est considérée comme une solution pour contribuer à la réduction des émissions de gaz à effet de serre dans l'atmosphère. Les interactions entre le CO 2 supercritique et la roche-réservoir potentielle doivent être étudiées en détail en conditions de stockage géologique. Quarante échantillons de calcaire de Lavoux et de grès d'Adamswiller, provenant de roches réservoirs du bassin parisien, ont été expérimentalement exposés au CO 2 dans un autoclave spécialement construit pour reproduire les conditions thermodynamiques d'un réservoir de stockage de CO 2 . Les deux types de roches ont été exposés pendant un mois à du CO 2 supercritique humide et à de l'eau saturée en CO 2 , à 28 MPa et 90°C, ce qui correspond à des conditions d'enfouissement de 3 km de profondeur. L'évolution de leurs propriétés minéralogiques a été suivie par des analyses par diffraction des rayons X, par spectroscopie Raman et par microscopie électronique couplée à un système de microanalyses X. Leurs propriétés physiques et microtexturales ont été estimées en mesurant, avant et après les expériences, le poids, la densité, les propriétés mécaniques, la perméabilité, la porosité globale et la présence d'éventuels gradients de porosité de chaque échantillon. Les résultats montrent que les deux roches ont préservé leurs propriétés mécaniques et minéralogiques, malgré une augmentation de la porosité et de la perméabilité. Des zones microscopiques de dissolution de la calcite observées dans le calcaire sont vraisemblablement responsables de cette augmentation de la perméabilité et de la porosité. Dans le grès, une altération de la pétro-fabrique est supposée se produire due à la réaction des minéraux argileux avec le CO 2 . Tous les échantillons du calcaire de Lavoux et du grès d'Adamswiller ont montré une altération mesurable dans le CO 2 humide et dans l'eau chargée en CO 2 . Ces expériences en autoclave sont effectuées en utilisant de l'eau distillée et donc simulent des conditions plus sévères que si elles étaient effectuées avec de l'eau de formation (saumure).
