... Abstract Deep saline aquifer is deemed as an effective and promising site for carbon sequestration. A geological storage site must be operated safely; however, CO 2 may leak through several pathways, such as fractures, faults and/or improperly plugged wells. This study presents a new...

... Abstract Geological carbon sequestration through injecting large-scale carbon dioxide (CO 2 ) into the deep saline aquifers represents a long-term storage of CO 2 . In the CO 2 sequestration process, the injected CO 2 is displacing water from the injection point and is expected to remain...

... ABSTRACT Saline aquifers, among other potential CO 2 storage formations, have been proven to offer the highest storage capacity necessary for commercial-scale carbon capture and storage (CCS) projects. They are an ideal target for emission reduction from coal-fired power plants...

... Abstract When CO 2 migrates upwards under buoyancy in the subsurface saline aquifer and encounters local capillary barriers (regions of rock with large capillary entry pressure), CO 2 would accumulate beneath these small barriers, and these accumulations are called local capillary trapping...

... of CO2 into the underground formation. While injecting CO2 into the formation, residual gas trapping and solubility trapping are the most important trapping mechanisms for CO2 storage in saline aquifers. The lack of information about the geological formation results in uncertainties in specifying...

... Abstract Sequestration of carbon dioxide in geological formations has drawn increasing consideration as a potential method to reduce the level of CO2 in the atmosphere, and therefore mitigate climate change. In particular, saline aquifers can potentially provide a large storage volume world...

... sequestration storage repositories in close proximity to major carbon dioxide emission sources. The suitable geologic sequestration storage repositories include depleted oil reservoirs and extensive saline aquifers. The overall feasibility is controlled by geologic suitability of the repositories...

... Abstract Storage of CO2 into geological formations is a reasonable technical choice for decreasing carbon dioxide emissions to the atmosphere. The dissolution of supercritical CO2 in formation water is one of the main long term trapping mechanisms for CO2 storage into saline aquifers...

... Abstract Geological storage of carbon dioxide has been recognized as one of the most effective options for mitigation of industrial emissions. Deep saline formations, otherwise called saline aquifers, are among the potential sequestration targets. To enhance the confidence regarding some...
