Numerical Modeling of the Effect of Carbon Dioxide Sequestration on the Rate of Pressure Solution Creep in Limestone: Preliminary Results

Abstract: Résumé -Simulation numérique de l'effet du stockage souterrain de dioxyde de carbone sur la déformation des calcaires par dissolution sous contrainte : résultats préliminaires -Lors de l'injection de dioxyde de carbone dans un réservoir déplété ou dans un aquifère, la dissolution du CO 2 dans l'eau de formation produit une acidification. Ce phénomène accélère les réactions de dissolutionprécipitation avec la matrice rocheuse, et par conséquent, peut modifier notablement les propriétés mécaniques et hydraulique… Show more

“…Calcite: 1.6-to-3.2×10 −5 mol · m −2 s −1 (Brosse et al, 2005) · Faster than aluminosilicates · Solubility depends on T, P, Salinity, ionic concentration, and pH · Dissolution rate is fast, but overall amount of reaction is small · Results in pH from 3 to 5 Sources: (a) (Drever, 1997); (b) (Li et al, 2006); (c) (Algive et al, 2009;Fredd and Fogler, 1998;Renard et al, 2005;Stumm and Morgan, 1996) D. N. Espinoza, S. H. Kim, and J. C Table 2 summarizes representative chemical reactions, typical reaction rates and related comments. The equilibrium constant for dissolution reaction denotes the concentration of produced species relative to the concentration of reactant species at steady state conditions, i.e., a function of mineral solubility.…”

“…(Stumm and Morgan, 1996). Furthermore, the reaction rate of minerals in CO 2 -water depends on temperature, pressure (i.e., CO 2 solubility and pH), and the concentration of other species (Algive et al, 2009;Fredd and Fogler, 1998;Pokrovsky et al, 2005;Renard et al, 2005). Dissolution rates for calcite CaCO 3 , anorthite CaAl 2 Si 2 O 8 , and kaolinite Al 2 Si 2 O 5 (OH) 4 are plotted as a function of pH in Fig.…”

“…Compaction by IPS is achieved by stress-driven dissolution of material from grain contacts that comprise the load-bearing framework of the aggregate. The dissolved material is transported out of the contacts by diffusion through a fluid film or a microscale channel network at the grain boundary, and then precipitated on the pore walls or removed from the system by long-range advection or diffusion [Lehner, 1990[Lehner, , 1995Renard et al, 1997Renard et al, , 2000Renard et al, , 2005Zubtsov et al, 2005]. In this way, IPS plays a key role in the reduction of porosity and permeability of rocks under diagenetic and low-grade metamorphic conditions, exerting important controls on the quality of hydrocarbon reservoirs, sealing capacity of reservoirbounding faults, and evolution of the strength properties of fault zones .…”

“…A second group of articles, [16][17][18], focuses on the question of model calibration, or validation, that can be drawn from well defined experiments. Finally, papers [19][20][21][22][23] present new or improved modelling tools from a very large range of topics, from liquid-vapour equilibria to more prospective future ab initio molecular calculations, through activity corrections, coupling between chemistry and mechanics, and solid solutions. …”
