Funding Acknowledgements

The authors thank the team of people helping coordinate the Darling Basin Drilling Program and the CO2CRC Otway 2BX experiment, including graduate and undergraduate students Syed Anas Ali, Cesar Castaneda-Herrera and Scott Ooi for their help conducting the fieldwork at the Otway site. Thank you to laboratory staff at Geoscience Australia for help with analytical equipment. We thank Lawrence Berkeley National Laboratory for providing access to the U- tube system at the CO2CRC Otway site, the CO2CRC site operator (Upstream Production Solutions), Mr Rajindar Singh (CO2CRC Ltd.) and Dr Chris Spero (COSPL) for their invaluable logistical and on site support at the Otway site. We acknowledge funding provided by the CO2CRC Ltd and Callide Oxyfuel Services Pty Ltd (COSPL). COSPL is a joint venture between Australian and Japanese companies and governments. Analysis of the data acquired from the Darling Basin drilling program was conducted by the CO2CRC with financial and logistical support by the NSW Department of Industry. The authors appreciatively acknowledge the Australia Geophysical Observing System (AGOS/AuScope) who provided significant funding supporting the sampling of formation water as part of the geochemical studies for the Darling Basin study. We thank the Assistant Editor Dr. Charles Jenkins and three anonymous reviewers for their comments on the manuscript.
