A method and apparatus are described for sequestering carbon dioxide underground by mineralizing the carbon dioxide with coinjected fluids and minerals remaining from the extraction shale oil. In one embodiment, the oil shale of an illite-rich oil shale is heated to pyrolyze the shale underground, and carbon dioxide is provided to the remaining depleted oil shale while at an elevated temperature. Conditions are sufficient to mineralize the carbon dioxide.

La présente invention concerne un procédé et un appareil permettant de séquestrer du dioxyde de carbone sous terre en minéralisant le dioxyde de carbone par co-injection de fluides et de minéraux laissés par l'extraction de schistes bitumineux. Dans un mode de réalisation, on chauffe le schiste bitumineux d'un schiste bitumineux riche en illite pour pyrolyser le schiste sous terre, et on apporte du dioxyde de carbone au schiste bitumineux épuisé résiduel en travaillant à température élevée. Ces conditions sont suffisantes pour minéraliser le dioxyde de carbone.
