Dissolution and Precipitation of Clay Minerals under Geologic CO2 Sequestration Conditions: CO2−Brine−Phlogopite Interactions

Redox-driven dissolution of clay minerals by uranium under high pressure CO2 conditions

Remote sensing of CO2 leakage from geologic sequestration projects

Monitoring for leak hazards is an important consideration in the deployment of carbon dioxide geologic sequestration. Failure to detect and correct leaks may invalidate any potential emissions benefits intended by such projects. Presented is a review of remote sensing methods primed to serve a central role in any monitoring program due to their minimally invasive nature and potential for large ...

Efficient Parallel Simulation of CO2 Geologic Sequestration in Saline Aquifers

An efficient parallel simulator for large-scale, long-term CO2 geologic sequestration in saline aquifers has been developed. The parallel simulator is a three-dimensional, fully implicit model that solves large, sparse linear systems arising from discretization of the partial differential equations for mass and energy balance in porous and fractured media. The simulator is based on the ECO2N mo...

Influence of CO2 Dissolution and Asphaltene Precipitation on Oil PVT and Recovery

PFLOTRAN: Massively Parallel 3D Simulator for CO2 Sequestration in Geologic Media

Geologic sequestration in depleted oil reservoirs, saline aquifers, etc. has been proposed as an effective way to stabilize the concentration of CO2 in the atmosphere and thus mitigate its effect on global climate change. We have developed a massively parallel 3-D reservoir simulator PFLOTRAN for modeling supercritical CO2 sequestration in geologic formations based on continuum scale mass and e...
