International agreements on the need to reduce the emissions of greenhouse gases into the atmosphere may bring forward geo-storage of CO2. Several technologies are suited to recover CO2 from power production and industrial point sources. These emissions represent significant parts of the CO2 emissions in industrialized regions. Separation of CO2 from power plant flue gases, compression, pipeline transport and deposition will increase the electricity cost by approximately 50%, but the use of CO2 to recover additional oil may offer a significant value for large quantities of CO2. Underground storage in petroleum reservoirs and aquifers has a large capacity and is environmentally safe. On a long term the deposition capacity in oil reservoirs is limited, but at present, petroleum reservoirs represent significant sinks for CO2. Underground storage of CO2 both in petroleum reservoirs and aquifers offers new business opportunities for the petroleum industry. The petroleum industry has a long time experience with all the operations and aspects involved with transport and injection of CO2 and other fluids into underground formations. |
