Described is a method for downhole sequestration of carbon dioxide. A heating assembly is lowered into a wellbore within a geological formation. Carbon dioxide is injected into the wellbore and heated to a predetermined temperature using the heating assembly. The heated carbon dioxide is allowed to migrate from the wellbore into the geological formation for permanent storage. A monitoring operation is performed to detect the formation of gas hydrates within the wellbore.

A method for sequestering COin a subterranean formation and a method for sequestering COin a subterranean formation during an enhanced oil recovery treatment include preparing a solution comprising COand from 0.01% by weight (wt. %) to 10 wt. % of a COsoluble alkoxylate surfactant based on the total weight of CO, processing the solution through a dispersing unit in fluid communication with an injection well, and injecting the dispersion into the injection well of the formation, thereby sequestering COin the formation. The method for sequestering COin a subterranean formation during an enhanced oil recovery treatment includes introducing an enhanced oil recovery treatment to the formation. A system for sequestering COin a formation includes an injection well in fluid communication with a formation, an injection unit, and a dispersing unit that is in fluid communication with the injection unit and the injection well.

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.
