Understanding the carbon dioxide sequestration in low‐permeability saline aquifers in the Ordos Basin with numerical simulations

A carbon dioxide (CO 2 ) capture and storage demonstration project was started in 2010 by injecting around 100 000 tonnes of super‐critical CO 2 per annum into a set of very low‐permeability sandstone at depths of more than 1600 m in the northeastern Ordos Basin, China. Based on the site‐specific geology and the observational data, a numerical injection model was developed in order to understand the hydrodynamic behavior of CO 2 in the...
