Abstract
Mineralizing carbon dioxide for storage may occur in a wellbore. For example, a method of mineralizing carbon dioxide may include: introducing, through a first wellbore to a subterranean formation, a first solution including a metal salt and a metal catalyst; introducing a second solution including a brine, wherein the second solution has nanobubble carbon dioxide at least partially dispersed therein, and wherein the second solution is introduced after introduction of the first solution; injecting carbon dioxide gas thereby at least partially dispersing the carbon dioxide gas in the first solution, thereby forming dissolved carbon dioxide; generating mineralized carbon dioxide from the dissolved carbon dioxide, wherein the generating includes catalytically reacting the metal salt and the dissolved carbon dioxide using the metal catalyst, thereby forming the mineralized carbon dioxide; and depositing the mineralized carbon dioxide within the subterranean formation.
