A geological storage option for CO2 in the Bohaiwan Basin, East China?

Geological assessment of the Bohaiwan Basin in eastern China for the COACH (Cooperation Action within CCS China-EU) project indicated that storing carbon dioxide (CO2) in this region will be technically challenging and require a flexible storage solution. It is suggested that a pilot scheme within the Dagang oil field complex could prove the concept of Carbon Capture and Storage (CCS) and CO2-Enhanced Oil Recovery (CO2-EOR) in the challenging conditions of oil fields in this region of China. This could be followed by simultaneous injection of CO2 into a nearby larger oil field and adjacent aquifers that would offer a potential storage option by combining the larger storage space anticipated for aquifers with the possible future financial incentives of CO2-EOR.
