Abstract: A method for storing CO2 includes identifying a depleted or partially depleted gas, gas condensate or oil reservoir having a plurality of injection wells and a plurality of production wells. The reservoir is then depleted. Once the reservoir is depleted or partially depleted, enhanced oil recovery and/or enhanced gas recovery is then performed on the reservoir where a first quantity of carbon dioxide is injected into the plurality of injection wells to displace the remaining oil and gas. Heat mining is then performed on the reservoir, where the second quantity of carbon dioxide is injected into the reservoir and the first and second quantities of carbon dioxide are subsequently produced to the surface for capture and conversion of geothermal heat of the first and second quantities of carbon dioxide into electricity. A third quantity of carbon dioxide is then injected and stored in the reservoir permanently.

Abstract: A CO2 sequestration system sequesters carbon dioxide as carbon dioxide hydrate in offshore saline aquifers. The system includes an offshore aquifer in a tropical region. A plurality of wellbores are positioned inside or around a perimeter of the aquifer. The CO2 may be injected into the aquifer via separate injectors located in the wellbores connected to the aquifer while aquifer water or brine is produced from one or more of the other wellbores and provided to the aquifer. Injection of the CO2 into and production of water from the offshore aquifer at separately timed intervals may maintain the reservoir pressure below the reservoir fracture pressure and the hydrate formation pressure so that the CO2 may be stored as carbon dioxide hydrate within the aquifer. Depending on the specific output desired, the aquifer may be positioned either straddling or within a hydrate stability zone. A method for sequestering CO2 uses the aforementioned system to carry out CO2 sequestration.
