Abstract
Sequestration of anthropogenic CO2 into subsurface geologic formation is the most reliable methodology in stabilizing the ever increasing CO2 concentration in atmosphere. However the sequestered buoyant CO2 always tends to migrate back to the atmosphere through possible migration pathways. Ensuring storage safety by accelerating dissolution trapping is the only possible methodology, while dissolution is a strong function of pressure, temperature, salinity and local availability of brine. In the present paper, an attempt has been made to investigate the effect of salinity on accelerating dissolution of CO2 in resident brine. It has been observed that low saline brine injection enormously increases the dissolution trapping mechanism of injected CO2. © 2017 The Authors.
