Abstract In order to evaluate chemical impacts of SO 2 impurity on reservoir rock during CO 2 capture and storage in deep saline aquifers, several batch reactor experiments were performed on laboratory scale using core rock samples from the pilot CO 2 injection site in Heletz. In this experiment, the samples were exposed to pure N 2 (g), pure CO 2 (g), and CO 2 (g) with an impurity of 1.5% SO 2 (g) under reservoir conditions for pressure and temperature (14.5 MPa, 60 °C). Based on the set-up and the obtained experimental results, a batch chemical model was established using the numerical simulation program TOUGHREACT V3.0-OMP. Comparing laboratory and simulation data provides a better understanding of the rock-brine-gas interactions. In addition, it offers an evaluation of the capability of the model to predict chemical interactions in the target injection reservoir during exposure to pure and impure CO 2 . The best match between the geochemical model and experimental data was achieved when the reactive surface area of minerals in the model was adjusted in order to calibrate the kinetic rates of minerals. The simulations indicated that SO 2 (g) tends to dissolve rather quickly and oxidizes under a kinetic control. Hence, it has a stronger effect on the acidity of the brine than pure CO 2 (g) and as a result, increased mineral dissolution and caused the precipitation of sulfate and sulfide minerals. Ankerite, dolomite, and siderite, the most abundant carbonates in the sandstone rock sample, are subject to stronger dissolution in the presence of SO 2 gas. The performed simulations confirmed a slower dissolution rate for ankerite and siderite than for dolomite. The model reproduced the precipitation of pyrite and anhydrite as observed in the laboratory. The dissolution of dolomite observed in the batch reaction test with pure N 2 is assumed to be due to slight contamination with oxygen and modelling supported this. The inclusion of SO 2 increased the porosity over that of the pure CO 2 case, and is thus considered to increase the permeability and injectivity of the reservoir as well. Exposure to SO 2 also increased the concentration of trace elements. The calibrated kinetic parameters determined in this study will be used to model the injection and long-term behavior of CO 2 at the Heletz field site, and may be used for similar geologic reservoirs.

Abstract The effect of pure and impure carbon dioxide (CO 2 ) on geological storage is uncertain. Oxidation of impurities such as sulfur dioxide (SO 2 ) and hydrogen sulfide (H 2 S), which may be catalyzed by co-injected oxygen or nitrogen oxides, leads to the formation of sulfuric acid (H 2 SO 4 ) and a decrease in pH of the formation water. We investigated the effect of 0.005 mol L − 1 H 2 SO 4 (corresponding to a worst case of 0.4% SO 2 in the flue gas, anticipating total conversion of SO 2 i...

Abstract Reservoir and cap-rock core samples with variable lithology's representative of siliciclastic reservoirs used for CO 2 storage have been characterized and reacted at reservoir conditions with an impure CO 2 stream and low salinity brine. Cores from a target CO 2 storage site in Queensland, Australia were tested. Mineralogical controls on the resulting changes to porosity and water chemistry have been identified. The tested siliciclastic reservoir core samples can be grouped generally in...

Abstract Many simulation studies on CO 2 storage in deep saline aquifers focus on flow transport modelling and pressure development. Studies including geochemical aspects mostly address the acidic impact of pure CO 2 injection on the minerals of the reservoir complex. More recent reactive transport simulations respect compositions of a flue gas stream closer to reality, i.e. they include physical or geochemical impacts of impurities within the CO 2 stream. Here the common approach is to introduc...

Abstract In order to assess the long-term security of geologic carbon storage, it is crucial to study the geochemical behavior of sulfur in reservoirs that store CO2. Fossil fuel combustion may produce mixtures of carbon dioxide and sulfur gases, and the geochemical effects of sulfur–CO2 cosequestration are poorly understood. This study examines sulfur mineralization from a core drilled in a stacked sequence of natural CO2 reservoirs near the town of Green River, Utah. These reservoirs include t...

Abstract Among the various risks associated with CO 2 storage in deep geologic formations, wells are important potential pathways for fluid leaks and groundwater contamination. Injection of CO 2 will perturb the storage reservoir and any wells that penetrate the CO 2 or pressure footprints are potential pathways for leakage of CO 2 and/or reservoir brine. Well leakage is of particular concern for regions with a long history of oil and gas exploration because they are top candidates for geologic ...

Saline aquifers in deep sedimentary formations are considered the primary candidates for geological storage of CO2, due to their large volumetric capacity that would be sufficient to meet the needs for CCS storage space in a global scale. In comparison to depleted oil and gas reservoirs the deep saline aquifers are, however, less investigated as there has previously been little economic interest in them. Effective methods for characterizing the storage aquifers are crucial for a successful imple...

Injected CO2 streams may have geochemical reactivity to different rock types in a CO2 storage complex depending on solubility and formation water chemistry. The Precipice Sandstone and Evergreen Formation are a low-salinity reservoir-seal pair in the Surat Basin, Australia, targeted for potential CO2 storage. The kinetic geochemical CO2 reactivity of different rock Facies from three regions were predicted over 30 and 1000 year time periods. No material CO2 mineral trapping in the quartz-rich Pre...
Laboratory experiments (150 days) were performed to analyze the influence of NO2 impurities on indigenous microbial communities and diversity with 16S rRNA sequence at real GCS site (Geological CO2 Sequestration, ordos, China) conditions (pressure: 15 MPa, temperature: 55 °C). The possible impact of metabolic activity on the GCS process was investigated through the BLASTn search. Compared with the pure CO2, results demonstrate that the biomass and biodiversity were lower, due to the lower pH, wi...

Abstract Chemical reaction simulations are considerably used to quantitatively assess the long-term geologic carbon sequestration (GCS), such as CO2 sequestration capacity estimations, leakage pathway analyses, enhanced oil recovery (EOR) efficiency studies, and risk assessments of sealing formations (caprocks), wellbores, and overlying underground water resources. All these require a deep understanding of the CO2 -associated chemical reactions. To ensure long-term, safe CO2 sequestration in the...

Abstract A demonstration project for the geological storage of CO2 is currently being considered in the deep Precipice Sandstone formation of the Surat Basin, Queensland, Australia. Because of the presence of potential fresh water resources in this formation, a reservoir-scale two-dimensional reactive-transport model was developed to assess temporal and spatial changes in water quality imposed by co-injecting CO2 with SO2, NO2, and O2 at this location. The model shows that because the injection ...
