Methods for storing carbon dioxide in a subsurface formation include identifying a plurality of negative geologic closures in the subsurface formation. The dimensions of the plurality of negative geologic closures are characterized. Layers of subsurface formation in the vicinity the negative geologic closures are characterized. One of the negative geologic closures is selected for bottom-up storage of carbon dioxide based on the characterized dimensions and layers.

Bottom-up sequestration of carbon dioxide in negative geologic closures

A method and system for both enhancing oil recovery of a reservoir and permanently sequestering carbon dioxide (CO) is described. The method includes dissolving COin a base fluid at a surface location of an injection formation, forming a dense CO-brine solution, introducing the dense CO-brine solution into an injection well, accumulating a volume of the dense CO-brine solution in a structural low, displacing a native formation fluid from the injection well, increasing a fluid drive pressure from the injection well to a producing well, and displacing hydrocarbons of the producing well. The system includes an injection system in fluid communication with an injection well, a production well of the hydrocarbon production formation, and a dense CO-brine solution that has a density greater than a native formation fluid of the injection formation.
