Geologic carbon dioxide storage is one strategy for reducing CO2 emissions into the atmosphere. Depleted natural gas reservoirs are an obvious target for CO2 storage due to their proven record of gas containment. Germany has both large industrial sources of CO2 and depleting gas reservoirs. The purpose of this report is to describe the analysis and modeling performed to investigate the feasibility of injecting CO2 into nearly depleted gas reservoirs in the Altmark area in North Germany for geologic CO2 storage with enhanced gas recovery.
