Wired News: Cut Emissions and Pump More Oil

Some good news for oil, for a change?

Just how much CO2 is produced during oil refining, anyway? The article claims that pumping the gas back into oil fields in Western Canada alone could reduce "CO2 emissions to the tune of pulling more than 200 million cars off the road for a year".

The lifetime of the field where testing has occurred has been extended for another 20 years. The subsurface rock in that field is sedimentary; the article claims that, if the technique were tried in basalt fields, the re-injected gas would be converted to calcium carbonate in less than 18 months. From volcanic rock to chalk -- who knew.
