Large-scale impact of CO2 storage in deep saline aquifers: A sensitivity study on pressure response in stratified systems
Abstract Large volumes of CO2 captured from carbon emitters (such as coal-fired power plants) may be stored in deep saline aquifers as a means of mitigating climate change. Storing these additionalExpand

A method for quick assessment of CO2 storage capacity in closed and semi-closed saline formations
Saline aquifers of high permeability bounded by overlying/underlying seals may be sur- rounded laterally by low-permeability zones, possibly caused by natural heterogeneity and/ or faulting. CarbonExpand

Modeling basin- and plume-scale processes of CO2 storage for full-scale deployment.
Integrated modeling of basin- and plume-scale processes induced by full-scale deployment of CO(2) storage was applied to the Mt. Simon Aquifer in the Illinois Basin. A three-dimensional mesh wasExpand

Basin-scale hydrogeologic impacts of CO2 storage: Capacity and regulatory implications
Industrial-scale injection of CO2 into saline formations in sedimentary basins will cause large-scale fluid pressurization and migration of native brines, which may affect valuable groundwaterExpand

Field-scale effective matrix diffusion coefficient for fractured rock: results from literature survey.
Matrix diffusion is an important mechanism for solute transport in fractured rock. We recently conducted a literature survey on the effective matrix diffusion coefficient, D(m)(e), a key parameterExpand

Saltwater Upconing and Decay Beneath a Well Pumping Above an Interface Zone
Saltwater, or brine, underlies freshwater in many aquifers, with a transition zone separating them. Pumping freshwater by a well located above the transition zone produces upconing of the latter,Expand

Analytical solutions for pressure perturbation and fluid leakage through aquitards and wells in multilayered aquifer systems
[1] Large-scale groundwater pumping or deep fluid injection in a multilayered subsurface system may generate pressure perturbation not only in the target formation(s), but also in over- andExpand

Making sense of global sensitivity analyses
TLDR
We re-interpret the variance-based sensitivity indices from the Sobol'/Saltelli method as difference-based measures that quantify the relative contribution of each parameter to the uncertainty in outputs. Expand

Pressure buildup and brine migration during CO2 storage in multilayered aquifers.
Carbon dioxide injection into deep saline formations may induce large-scale pressure increases and migration of native fluid. Local high-conductivity features, such as improperly abandoned wells orExpand

Dynamic displacement and non-equilibrium dissolution of supercritical CO2 in low-permeability sandstone: An experimental study
Abstract An experimental setup was developed for conducting core-flood experiments of supercritical CO2 and water under pressures higher than 8.00 MPa and a temperature of 40 °C. Two representativeExpand
