Numerical simulation of CO2 injection into deep saline aquifers
In the last two centuries, atmospheric concentrations of carbon dioxide (CO2) have augmented by about 35% as a result of increased anthropogenic emissions. To reduce these emissions, geologic Carbon Capture and Sequestration (CCS) has been advanced as an emerging technology. Current estimations report that 60% are of the total storage capacity under the subsurface is included in deep saline for...
متن کاملCO2 Storage in Saline Aquifers
CO2 Storage in Saline Aquifers — Saline aquifers represent a promising way for CO2 sequestration. Storage capacities of saline aquifers are very important around the world. The Sleipner site in the North Sea is currently the single case world-wide of CO2 storage in a saline aquifer. A general review is given on the specific risks for CO2 storage in saline aquifer. The regional distribution of C...
متن کاملAnalytical Modeling of CO2 Migration in Saline Aquifers for Geological CO2 Storage
Injection of carbon dioxide into geological formations for long-term storage is widely regarded as a promising tool for reducing global atmospheric CO2 emissions. Given the environmental and health risks associated with leakage of CO2 from such a storage site, it is critical to ensure that injected CO2 remain trapped underground for the foreseeable future. Careful site selection and effective i...
متن کاملOptimization of CO2 Sequestration in Saline Aquifers
For optimization of geological carbon sequestration (GCS) in saline aquifers, a genetic algorithm (GA) based optimizer has been developed and combined with the DOE multi-phase flow and heat transfer numerical simulation code TOUGH2 [1],[2]. Designated GA-TOUGH2, this combined solver/optimizer has been validated by performing optimization studies on a number of model problems and comparing the r...
متن کاملCoupled Hydromechanical Modeling of Co2 Sequestration in Deep Saline Aquifers
Sequestration of carbon dioxide (CO2) in deep saline aquifers has emerged as an option for reducing greenhouse gas emissions to the atmosphere. The large amounts of supercritical CO2 that need to be injected into deep saline aquifers may cause large fluid pressure increases. The resulting overpressure may promote reactivation of sealed fractures or the creation of new ones in the caprock seal. ...
