Abstract
Methods for carbon dioxide sequestration may comprise: introducing a fluid stream comprising carbon dioxide into an encapsulated salt minibasin, the encapsulated salt minibasin being surrounded by a salt barrier defining one or more boundaries thereof; and storing carbon dioxide from the fluid stream within the encapsulated salt minibasin after introduction thereto, the salt barrier retaining the carbon dioxide within the encapsulated salt minibasin.
Claims22
A method comprising:
- introducing a fluid stream comprising carbon dioxide into an encapsulated salt minibasin, the encapsulated salt minibasin comprising a sedimentary rock deposit surrounded by a salt barrier, the salt barrier defining one or more boundaries of the encapsulated salt minibasin;
- and
- storing carbon dioxide from the fluid stream within the sedimentary rock deposit of the encapsulated salt minibasin after introduction thereto, the salt barrier retaining the carbon dioxide within the encapsulated salt minibasin.
A method comprising:
- providing a fluid stream comprising a carbonated aqueous fluid, gaseous carbon dioxide, supercritical carbon dioxide, or any combination thereof;
- introducing the fluid stream into an encapsulated salt minibasin, the encapsulated salt minibasin containing formation water native to the encapsulated salt minibasin and the encapsulated salt minibasin comprising a sedimentary rock deposit surrounded by a salt barrier, the salt barrier defining one or more boundaries of the encapsulated salt minibasin;
- withdrawing at least a portion of the formation water from the encapsulated salt minibasin to decrease pressure therein;
- and
- storing carbon dioxide from the fluid stream within the sedimentary rock deposit of the encapsulated salt minibasin after introduction thereto, the salt barrier retaining the carbon dioxide within the encapsulated salt minibasin.
