Abstract
A method may include: introducing a resin modified cement slurry into a wellbore penetrating a subterranean formation, the subterranean formation comprising a caprock and a carbon dioxide injection zone, the resin modified cement slurry comprising: a resin; a hardener, a hydraulic cement; and water; and setting the resin modified cement slurry to form a set cement wherein the set cement forms a carbonation-resistant barrier in the carbon dioxide injection zone in the subterranean formation.
Claims20
A method comprising:
- providing a carbon capture underground storage system, wherein the carbon capture underground storage system comprises:
- a wellbore penetrating a subterranean formation comprising a carbon dioxide injection zone;
- and
- a carbonation-resistant barrier, wherein the carbonation-resistant barrier comprises a set cement formed from a resin modified cement slurry comprising a liquid curable resin, a hardener, a hydraulic cement, and water, wherein a combination of the liquid curable resin and the hardener within the resin modified cement slurry impedes carbonation by either a hydrophobicity or an ability to repel water and wherein the carbonation-resistant barrier is resistant to carbonation for a period of one month or greater as measured by a pH indicator solution test,
- wherein the liquid curable resin comprises bisphenol A diglycidyl ether resins wherein the resin is present in an amount of about 21 wt. % to about 60 wt. %;
- wherein the hardener comprises aromatic amines wherein the hardener is present in an amount of about 1 wt. % to about 20 wt. %;
- and wherein the carbonation-resistant barrier overlaps with at least a portion of the carbon dioxide injection zone in the subterranean formation;
- introducing carbon dioxide into the carbon capture underground storage system;
- and
- flowing the carbon dioxide into the carbon dioxide injection zone.
