Abstract
Methods of capturing carbon dioxide in a wellbore can include installing a sealing element in the wellbore. The sealing element swells in the presence of carbon dioxide and can be used for capturing the carbon. The sealing element can include a carbon-swelling material, such as a carbon-swelling polymers, metal-based materials, or combinations of elastomeric polymers and metal-based materials. The sealing element can also include combinations of different carbon-swelling materials, fillers or other compounds, and materials that are not carbon swellable. The sealing element can create a seal, form an anchor, or create a seal and form an anchor in the wellbore after swelling.
Claims20
A method of capturing carbon in a subterranean formation comprising:
- installing a sealing element in a wellbore that penetrates the subterranean formation, wherein the sealing element swells in the presence of carbon dioxide, and wherein the sealing element comprises a metal-based material, wherein the metal-based material is a compound comprising a framework and metal nodes that are linked together by organic ligand bridges;
- and
- contacting the sealing element with carbon dioxide.
A well system comprising:
- a wellbore that penetrates a subterranean formation;
- a tubing string located within the wellbore;
- and
- a sealing element located adjacent to the tubing string, wherein the sealing element swells in the presence of carbon dioxide, and wherein the sealing element comprises a metal-based material, wherein the metal-based material is a compound comprising a framework and metal nodes that are linked together by organic ligand bridges.
A downhole tool comprising:
- a mandrel;
- and
- a sealing element located adjacent to the mandrel, wherein the sealing element swells in the presence of carbon dioxide, and wherein the sealing element comprises a metal-based material, wherein the metal-based material is a compound comprising a framework and metal nodes that are linked together by organic ligand bridges.
