While on one hand, scientists are experimenting to see if underground lava rocks could be used as a storage depot for carbon dioxide created by humans, on the other Canadian oilfield have successfully stored five million tons of carbon dioxide, a gas linked to global warming! And this occurred while doubling the field’s crude oil recovery rate, the US Energy Department said. The technology seems promising. It is the multi-national project that could be used to capture and store carbon dioxide in geologic formations, U.S. officials said. Injecting carbon dioxide into the Weyburn oilfield in Saskatchewan, the project increases underground pressure to boost crude oil production by 10,000 barrels per day. Enhanced oil recovery, as the technique is called, is used by many oil companies to keep aging fields productive. But most oil companies typically uses more costly carbon dioxide from naturally occurring reservoirs.
