CO₂ sequestration with enhanced shale gas recovery

CO₂ enhanced shale gas recovery has the merits of both increasing the natural gas production to address the global energy crisis as well as simultaneously the geological storage of CO₂ to reduce the anthropogenic greenhouse gas emissions. Although it has huge development potential and wide application prospects, this technology is still in a very preliminary stage of deployment. The research status of the CO₂ enhanced shale gas recovery is summarized in this paper in order to stimulate further research and development in this field worldwide to address the dual problem of energy crisis and environmental degradation.
