Carbon dioxide (CO) injection into oil reservoirs is a proven technology that is emerging in Canada as an economic method to increase oil production from mature fields while sequestering CO2 emissions. Two commercial CO2 floods are currently operating in Alberta and Saskatchewan with a number of new projects identified for development. The Alberta and Saskatchewan governments have updated their royalty regulations to promote enhanced oil recovery and the industrial CO2 sources have been identified. The "building blocks" for a CO2 industry are being addressed, including the need for pipeline infrastructure to transport the CO2 from the industrial emission source to the commercial user. In the USA, the use of CO2 for enhanced oil recovery has resulted in the construction of about 2,500 km of pipeline. An ultimate network of about 2,000 kin of pipelines for CO2 collection and transport has been proposed for Alberta alone. This paper will overview aspects related to the design and potential routes for a CO2 pipeline backbone system that could develop to collect CO2 supplies from a variety of industrial sources for transportation to commercial markets.
