“…After a year of operation, 317,000 t of CO2 at the rate of 1100 t/d was injected into the formation using a single injection well. [89,247,310]. It was revealed that additional storage of 3-4.5 Mt of CO2 in the same saline aquifer would be feasible in a follow-up project [247].…”

Carbon capture and storage (CCS) has been identified as an urgent, strategic and essential approach to reduce anthropogenic CO2 emissions, and mitigate the severe consequences of climate change. CO2 storage is the last step in the CCS chain and can be implemented mainly through oceanic and underground geological sequestration, and mineral carbonation. This review paper aims to provide state-of-the-art developments in CO2 storage. The review initially discussed the potential options for CO2 storage by highlighting the present status, current challenges and uncertainties associated with further deployment of established approaches (such as storage in saline aquifers and depleted oil and gas reservoirs) and feasibility demonstration of relatively newer storage concepts (such as hydrate storage and CO2-based enhanced geothermal systems). The second part of the review outlined the critical criteria that are necessary for storage site selection, including geological, geothermal, geohazards, hydrodynamic, basin maturity, and economic, societal and environmental factors. In the third section, the focus was on identification of CO2 behaviour within the reservoir during and after injection, namely injection-induced seismicity, potential leakage pathways, and long-term containment complexities associated with CO2-brine-rock interaction. In addition, a detailed review on storage capacity estimation methods based on different geological media and trapping mechanisms was provided. Finally, an overview of major CO2 storage projects, including their overall outcomes, were outlined. This review indicates that although CO2 storage is a technically proven strategy, the discussed challenges need to be addressed in order to accelerate the deployment of the technology. In addition, beside the necessity of technoeconomic aspects, public acceptance of CO2 storage plays a central role in technology deployment, and the current ethical mechanisms need to be further improved.

“…The Cambrian Mount Simon Sandstone has for many years been the primary target in the basin for gas storage and for carbon dioxide sequestration (Morse and Leetaru, 2005;. Accordingly, much is known about this unit, especially compared to the under-lying Precambrian basement (Couëslan et al, 2009(Couëslan et al, , 2014a(Couëslan et al, , 2014b. The Precambrian beneath the basin comprises heterogeneous granitic composition igneous rocks and/or related metasedimentary strata, all presumably belonging to the eastern Granite-Rhyolite Province (EGRP;Sargent, 1991;Pratt et al, 1992;Van Schmus et al, 1996;McBride et al, 2003McBride et al, , 2010Fig.…”

“…Our study provides one of the best geophysically constrained observations of such reflectivity in a classic area of geological interest. Recent advancements in 2D and 3D seismic imaging, applied as part of a carbon sequestration program in the Illinois Basin (Couëslan et al, 2009(Couëslan et al, , 2013(Couëslan et al, , 2014a(Couëslan et al, , 2014bAlvi et al, 2013;McBride et al, 2014), provide a unique opportunity to employ state-of-the-art techniques to studying Precambrian geology beneath the basin.…”

Fine-scale structure of the Precambrian beneath the Illinois Basin

Increasing our understanding of the heterogeneity of Precambrian crust continues to be a focus for deep seismic reflection studies. High-resolution two-dimensional (2D) seismic profiles and a high-resolution 3D seismic volume, all centered on Decatur (Illinois, USA), provide new insights on the structure and composition of Precambrian basement beneath the Illinois Basin of the central USA midcontinent. The new data reveal a pattern of strong and coherent reflections and associated diffractions deeply buried within the eastern Granite-Rhyolite Province. This pattern is dominated by a thick seismic stratigraphic sequence, which is wedge or bowl shaped in cross section and has an angular unconformity with the overlying Paleozoic section. Deeper intrabasement bowl-shaped sequences or series are also observed in the same area. We interpret these features to be a northward continuation of analogous basement sequences located 75 km to the south below the southern part of the Illinois Basin. This correlation indicates a vast Precambrian province with a north-south dimension of >200 km. Although multiple explanations are admissible for the Precambrian reflectivity, the most likely for our study area is igneous intrusion of broad mafic igneous (diabase?) sills possibly underlain by small plutons. The concentration of such mafic (or bimodal) igneous activity within or coeval with the eastern Granite-Rhyolite Province suggests an episode of Proterozoic crustal extension and rifting.

“…11). The strike of the planes in relation to the in situ S Hmax fits the first motion analysis indicating right lateral strike-slip motions on many of the clusters (Couëslan et al, 2014). These planes are interpreted to be the reactivation of preexisting features as shown by the Gutenberg-Richter plots for all the microseismicity, which show b-values close to 1 (Fig.…”

a b s t r a c tThe Illinois Basin-Decatur Project safely and successfully injected, over three years, nearly 1.1 million tons (1 million tonnes) of supercritical carbon dioxide (CO 2 ) into the base of a 1640 ft (500 m) thick saline sandstone reservoir at a depth of 7025 ft (2.14 km). The injection interval, with its high porosity and permeability, allowed for injection pressures to be far below fracture pressures during the daily 1102 tons (1000 tonnes) injection rate. Microseismicity was monitored 1.5 years before injection, through the 3 years of injection and now during permanent shut-in which began in November 2014. The overall average of locatable events per day, during injection, was a little over 4, and events appear to be related to development on previously undetected planes of weakness. Some of these planes and active areas may be related to features developed during diagenetic or compactional processes associated with the Precambrian surface topography. Microseismicity during transient shut-in did not show a rate of decrease, large changes in magnitude, distance from the injection well, or depth.
