Geophone Array Optimization for Monitoring Geologic Carbon Sequestration using Double-Difference Tomography
… tomographic monitoring system for a geologic carbon sequestration injection site. Artificial velocity models were created that accounted for the expected velocity decrease due to the existence of a CO₂ plume after underground injection into a depleted petroleum reservoir. Seismic …

Silicate Mineral Dissolution and Associated Carbonate Precipitation at Conditions Relevant to Geologic Carbon Sequestration
<p>Geologic carbon sequestration: GCS) has been proposed as a means of mitigating the impacts of carbon dioxide: CO2) emissions from fossil fuel combustion on climate change. Mineral trapping, one of the trapping mechanisms of GCS, is of great importance because it has a potentially high …

Double-Difference Tomography Applied to Monitoring of Geologic Carbon Sequestration in the Aneth Oil Field, Utah
… seismic tomography is performed on a carbon sequestration operation in the Aneth Oil Field in southeast Utah as part of a Department of Energy initiative on monitoring, verification, and accounting of sequestered CO2. A total of 1,211 seismic events were recorded from a borehole array …

Coupling tough2 and SEAWAT variable-density models to understand potential geologic carbon sequestration impacts on groundwater resources
… Illinois Basin, is the storage reservoir for a geologic carbon sequestration (GCS) project in central Illinois (USA). The Mt. Simon is a highly saline reservoir at the injection location (Macon County), but its salinity decreases to the north, becoming a source of drinking water in Wisconsin. In …

Sociopolitical challenges to the siting of facilities with perceived environmental risks
… is likely to present a particular challenge is geologic carbon sequestration. This thesis uses a case study approach to develop a set of recommendations for preventing and, if required, dealing with local opposition to geologic carbon sequestration projects - and necessary but controversial …

Relative Permeability Experiments of Carbon Dioxide Displacing Brine and Their Implications for Carbon Sequestration
… warming and ocean acidification, anthropogenic carbon dioxide must be diverted from atmospheric release. For geologic carbon sequestration, the injection of CO 2 into the lithosphere, to operate at the necessary large scale requires an understanding of the multiphase flow properties of …

Surveying and harnessing the genetic, (meta)genomic, and metabolic potential of the deep carbonated biosphere
… between microbes and supercritical (sc) carbon dioxide represents an increasingly compelling area of research due to use of scCO₂ in geologic carbon sequestration (GCS) and as a sustainable chemical solvent. To investigate the long-term effects of GCS on the in situ deep subsurface …

Geochemical and geomechanical alteration of sandstone reservoir rock and shale caprock under representative geological carbon sequestration conditions
Geologic Carbon Sequestration is a method of mitigating anthropogenic climate change where CO₂ is captured from point-source emissions and transported to a location where it is injected into a rock formation in the subsurface for permanent storage. The dissolution of CO₂ into reservoir brine forms …

Demonstrating biocompatibility with supercritical CO₂ : biphasic cultivation of Bacillus spp. and probing acclimation mechanisms through proteome and lipid analysis
… the greenhouse gas CO₂ injected underground for geologic carbon sequestration (GCS). In this thesis I have described the isolation of microorganisms from three different carbon sequestration pilot sites through a novel method of successive scCO₂ enrichments. I show that microorganisms of the …

Implications of Permeability Uncertainty During Three-phase CO2 Flow in a Basalt Fracture Network
… continental flood basalts may be suitable for geologic carbon sequestration due to fluid-rock reactions that mineralize injected CO₂ on relatively short time-scales. Flood basalts also possess a permeability structure favorable for injection, with alternating high-permeability (flow margin) and …
