| 摘要 |
The present invention is directed to a new and improved method for sequestration of carbon dioxide, the method including the steps of injecting a carbon dioxide-containing injection gas into a subsurface containment region with a series of captures zones; providing sufficient time for said injection gas to at least partially stratify and form constituent gas mixtures which at least partially accumulate in the capture zones; providing a vent associated with one of the capture zones; and, evacuating at least a portion of the constituent mixtures through the associated vent.
