What is EOR?
In the oil industry, CO2 is pumped up as a byproduct (along with the natural gas and helium that oil companies need), and can either used to create pressure in oil and gas reservoirs to extract more fossil fuels – known as enhanced oil recovery (EOR) – or sold to other oil and gas companies. EOR is the only large-scale industrial use for CO2 and the only carbon-capture industry today of scale that makes a profit. However, while EOR can reduce the carbon intensity of oil, it also subsidizes the production of oil.
