An Integrated Economic And Engineering Assessment Of Opportunities For Co2 Injection With Water Production In South-East Queensland, Australia

The production and treatment of formation water from CO2 storage formations in south-east Queensland, Australia may have the dual benefits of improving CO2 injectivity, as well as, proving a supplementary source of water. Coal and gas-fired plants in this region generates about 25 Mt/yr of CO2 and consume approximately 36 GL/yr of water. The sedimentary basins in this area are thought to be some of Australia's best onshore prospects for CO2 injection. This paper suggests that water production can result in significant cost reductions and make storage sites much more prospective. In addition, there may be opportunities for selling water. CO2CRC.
