Abstract
Systems and methods of the present disclosure relate to storing carbon dioxide (CO2) underground. A method includes contacting a metal tool with the CO2 and forming hydrated metal carbonates (HMCs) on the tool due to contact of the CO2 with the metal of the tool. Expansion of the tool occurs due to formation of the HMCs.
Claims24
A method comprising:
- lowering a tool in a wellbore;
- injecting carbon dioxide (CO2) and/or carbon monoxide (CO) into the wellbore;
- contacting the tool with carbon dioxide (CO2) and/or carbon monoxide (CO), the tool comprising metal;
- forming hydrated metal carbonates (HMCs) on the tool with the CO2 and/or CO contacting the tool due to contact of the CO2 and/or CO with the metal of the tool;
- expanding a size and/or reducing a porosity of the tool due to formation of the HMCs;
- and
- displacing at least partially wellbore fluid from the wellbore by injecting CO2 and/or CO while the tool is disposed in the wellbore.

A method comprising:
- disposing a tool in a wellbore, the tool comprising metal;
- injecting carbon dioxide (CO2) and/or carbon monoxide (CO) into the wellbore;
- corroding the metal with a fluid of the wellbore to provide corroded metal;
- contacting the corroded metal with carbon dioxide (CO2) and/or carbon monoxide (CO);
- forming hydrated metal carbonates (HMCs) on the tool due to contact of the CO2 and/or the CO with the corroded metal;
- expanding a size and/or reducing a porosity of the tool due to formation of the HMCs;
- and
- displacing at least partially wellbore fluid from a wellbore by injecting CO2 and/or CO while the tool is disposed in the wellbore

(canceled)
A system comprising:
- a source in fluid communication with a well, the source configured to provide carbon dioxide (CO2) and/or carbon monoxide (CO) to the well;
- and
- a tool disposed in the well, the tool configured to form hydrated metal carbonates (HMCs) upon contact of a metal of the tool with the CO2 and/or the CO.
A downhole tool comprising:
- a portion configured to define a plug with formed hydrated metal carbonates (HMCs), the HMCs configured to form on the portion, and expand a size and/or reduce a porosity of the downhole tool, upon exposure of a metal of the downhole tool to CO2 and/or CO.
