CO2 Sequestration in Deep Sedimentary Formations
Sally M. Benson,David R. Cole +1 more
TL;DR: Carbon dioxide capture and sequestration (CCS) in deep geological formations has recently emerged as an important option for reducing greenhouse emissions as discussed by the authors, and if CCS is implemented on the scale needed to make noticeable reductions in atmospheric CO2, a billion metric tons or more must be sequestered annually, a 250 fold increase over the amount sequestered today.
Journal ArticleDOI
Role and impact of CO2–rock interactions during CO2 storage in sedimentary rocks
TL;DR: In this paper, the main aspects that are possibly affecting the safety and/or feasibility of the CO 2 storage scheme are reviewed and identified, based on each interaction environment, and the methodologies for assessing CO 2-rock interactions are discussed.

Carbon dioxide storage potential of shales
Andreas Busch,Sascha Alles,Yves Gensterblum,Dirk Prinz,David N. Dewhurst,Mark Raven,Helge Stanjek,Bernhard M. Krooss +7 more
TL;DR: In this article, diffusive transport and gas sorption experiments on one well characterised shale sample (Muderong Shale, Australia) and different clay minerals were performed to obtain information on the sealing integrity and the CO2 storage potential of these materials.
Journal ArticleDOI
The geomechanics of CO2 storage in deep sedimentary formations
TL;DR: In this paper, the authors provide a review of the geomechanics and modeling of geOMEchanics associated with geologic carbon storage (GCS), focusing on storage in deep sedimentary formations, in particular saline aquifers.
Journal ArticleDOI
Mineral Carbonation of CO2
TL;DR: CarbFix as discussed by the authors injects CO2 into permeable basaltic rocks in an attempt to form carbonate minerals directly through a coupled dissolution-precipitation process.

Aquifer disposal of CO2-rich greenhouse gases: Extension of the time scale of experiment for CO2-sequestering reactions by geochemical modelling
TL;DR: Gunter et al. as discussed by the authors suggested water-rock reactions in deep aquifers in sedimentary basins could sequester injected-CO2-waste from industry, thereby reducing greenhouse gas emissions.

Carbon dioxide reaction processes in a model brine aquifer at 200 °C and 200 bars: implications for geologic sequestration of carbon
TL;DR: The reactive behavior of supercritical CO2 under conditions relevant to geologic storage and sequestration of C is largely unknown as discussed by the authors, and the role of fluid-rock reactions, in addition to carbonate mineral precipitation, that may occur in a brine aquifer-aquitard system that simulates a saline aquifer storage scenario.
Journal ArticleDOI
Tracer diffusion coefficients in sedimentary rocks: correlation to porosity and hydraulic conductivity.
Thomas B. Boving,Peter Grathwohl +1 more
TL;DR: The results of the diffusion experiments indicate that there is a close relationship between total porosity and the effective diffusion coefficient of a rock (analogous to Archie's Law), and the tortousity factor can be expressed as a function oftotal porosity.
MonographDOI
Chemical Modeling of Aqueous Systems II.
Daniel C. Melchior,R. L. Bassett +1 more
TL;DR: In this paper, all aspects of reactions in aqueous systems were presented, including thermodynamics, equilibrium, mass transfer, and surface chemistry, both chemical and theoretical models were presented.
Journal ArticleDOI
Underground sequestration of carbon dioxide—a viable greenhouse gas mitigation option
TL;DR: Underground storage of industrial quantities of carbon dioxide in porous and permeable reservoir rocks has been taking place for the last 5 years at the Sleipner West gas field in the North Sea as mentioned in this paper.
