The Weyburn oilfield in SE Saskatchewan, Canada has been in production for more than 50 years. A CO 2 flood was started in 2000 to enhance oil recovery. The gas is piped from a coal gasification plant across the U S border in North Dakota. In addition to boosting oil production it is expected that about 30 million tonnes of CO 2 will be permanently stored in the reservoir, at a depth of about 1400 m, by the end of the 30 year lifetime of the project.
