Multi-scale Investigations of Geological Carbon Sequestration in Deep Saline Aquifers
Geological carbon dioxide (CO2) sequestration (GCS) in deep saline aquifers is viewed as a viable solution to dealing with the impact of anthropogenic CO2 emissions on global warming. The trapping mechanisms that control GCS include capillary trapping, structural trapping, dissolution trapping, and …

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 …

Numerical Simulation and Optimization of CO2 Sequestration in Saline Aquifers
… years on the development of safe and economical Geological Carbon Sequestration: GCS) technology. Although among one of the most promising technologies to address the problem of anthropogenic global-warming due to CO2 emissions, the detailed mechanisms of GCS are not well-understood. As a result, …
