“…Simulation results could be sensitive to the choice of secondary minerals. However, almost all possibilities of secondary carbonate and clay minerals are covered in the simulations, which are based on previous studies of modelling (Xu et al, 2005(Xu et al, , 2006Gaus et al, 2005;White et al, 2005), laboratory experiments (Wolf et al, 2004;Chen et al, 2006), and field observations (Pearce et al, 1996;Watson et al, 2004;Moore et al, 2005;Worden 2006). …”

The geological storage of CO 2 in deep saline formations is increasing seen as a viable strategy to reduce the release of greenhouse gases to the atmosphere. There are numerous sedimentary basins in China, in which a number of suitable CO 2 geologic reservoirs are potentially available. To identify the multi-phase processes, geochemical changes and mineral alteration, and CO 2 trapping mechanisms after CO 2 injection, reactive geochemical transport simulations using a simple 2D model were performed. Mineralogical composition and water chemistry from a deep saline formation of Songliao Basin were used. Results indicate that different storage forms of CO 2 vary with time. In the CO 2 injection period, a large amount of CO 2 remains as a free supercritical phase (gas trapping), and the amount dissolved in the formation water (solubility trapping) gradually increases. Later, gas trapping decreases, solubility trapping increases significantly due to migration and diffusion of the CO 2 plume, and the amount trapped by carbonate minerals increases gradually with time. The residual CO 2 gas keeps dissolving into groundwater and precipitating carbonate minerals. For the Songliao Basin sandstone, variations in the reaction rate and abundance of chlorite, and plagioclase composition affect significantly the estimates of mineral alteration and CO 2 storage in different trapping mechanisms. The effect of vertical permeability and residual gas saturation on the 2 overall storage is smaller compared to the geochemical factors. However, they can affect the spatial distribution of the injected CO 2 in the formations. The CO 2 mineral trapping capacity could be in the order of ten kilogram per cubic meter medium for the Songliao Basin sandstone, and may be higher depending on the composition of primary aluminosilicate minerals especially the content of Ca, Mg, and Fe.

“…On the other hand, they give only an approximation of the long-term phenomena that occur within the geologic space. Coupled numerical models, incorporating kinetic transport through porous media and thermodynamic issues of the multiphase system are the most helpful in prognosing the injection impact on the hosting and insulating rock environment (e.g., Gunter et al 1993;Perkins and Gunter 1995;White et al 2005).…”

Preliminary geochemical modeling of water–rock–gas interactions controlling CO2 storage in the Badenian Aquifer within Czech Part of Vienna Basin

Prediction of hydrogeochemical effects of geological CO 2 sequestration is crucial for planning an industrial or even experimental scale injection of carbon dioxide gas into geological formations. This paper presents a preliminary study of the suitability of saline aquifer associated with a depleted oil field in Czech Part of Vienna Basin, as potential greenhouse gas repository. Two steps of modeling enabled prediction of immediate changes in the aquifer and caprocks impacted by the first stage of CO 2 injection and the assessment of long-term effects of sequestration. Hydrochemical modeling and experimental tests of rock-water-gas interactions allowed for evaluation of trapping mechanisms and assessment of CO 2 storage capacity of the formations. In the analyzed aquifer, CO 2 gas may be locked in mineral form in dolomite and dawsonite, and the calculated trapping capacity reaches 13.22 kgCO 2 /m 3 . For the caprock, the only mineral able to trap CO 2 is dolomite, and trapping capacity equals to 5.07 kgCO 2 /m 3 .

“…The mineral dawsonite [NaAlCO 3 (OH) 2 ] was predicted to form in significant quantities as a CO 2 mineral trap in numerical reactive transport simulations of CO 2 injection into the Sleipner aquifers, North Sea JOHNSON et al, 2001), into the Navajo sandstone on the Colorado Plateau (White et al, 2005), into the Rose Run sandstone aquifer in Ohio (Zerai et al, 2006), and into sandstone aquifers resembling the Frio Formation in Texas (Xu et al, 2003;. However, there is a lack of experimental data to support these computer model predictions.…”

A Novel Approach to Experimental Studies of Mineral Dissolution Kinetics

Currently, DOE is conducting pilot CO 2 injection tests to evaluate the concept of geological sequestration. The injected CO 2 is expected to react with the host rocks and these reactions can potentially alter the porosity, permeability, and mechanical properties of the host or cap rocks. Reactions can also result in precipitation of carbonate-containing minerals that favorably and permanently trap CO 2 underground. Many numerical models have been used to predict these reactions for the carbon sequestration program. However, a firm experimental basis for predicting silicate reaction kinetics in CO 2 injected geological formations is urgently needed to assure the reliability of the geochemical models used for the assessments of carbon sequestration strategies. The funded experimental and theoretical study attempts to resolve this outstanding scientific issue by novel experimental design and theoretical interpretation of silicate dissolution rates at conditions pertinent to geological carbon sequestration.In this four year research grant (three years plus a one year no cost extension), seven (7) laboratory experiments of CO 2 -rock-water interactions were carried out. An experimental design allowed the collection of water samples during experiments in situ and thus prevented back reactions. Analysis of the in situ samples delineated the temporal evolution of aqueous chemistry because of CO 2 -rock-water interactions. The solid products of the experiments were retrieved at the end of the experimental run, and analyzed with a suite of advanced analytical and electron microscopic techniques (i.e., atomic resolution transmission electron microscopy (TEM), scanning electron microscopy (SEM), electron microprobe, X-ray diffraction, X-ray photoelectron spectroscopy (XPS)). As a result, the research project probably has produced one of the best data sets for CO 2 -rock-water interactions in terms of both aqueous solution chemistry and solid characterization. Three experiments were performed using the Navajo sandstone. Navajo sandstone is geologically equivalent to the Nugget sandstone, which is a target formation for a regional partnership injection project. Our experiments provided the experimental data on the potential CO 2 -rock-water interactions that are likely to occur in the aquifer. Geochemical modeling was performed to interpret the experimental results.Our single mineral (feldspar) experiments addressed a basic research need. i.e., the coupled nature of dissolution and precipitation reactions, which has universal implication to the reaction kinetics as it applied to CO 2 sequestration. Our whole rock experiments (Navajo sandstone) addressed the applied research component, e.g., reacting Navajo sandstone with brine and CO 2 has direct relevance on the activities of a number of regional partnerships.The following are the major findings from this project:1. The project generated a large amount of experimental data that is central to evaluating CO 2 -water-rcok interactions and providing ground truth to pred...
