Dr Geoff O'Brien

Chief Scientist - CO2CRC

Professional Bio

Dr O'Brien has a PhD in marine geochemistry and sedimentology (porewater diagenesis and organic carbon cycling) and has over 35 years’ experience in the marine research, petroleum and CCS sectors. He has worked in and for the petroleum industry as a petroleum systems and CCS technical specialist, with a focus on integrated petroleum systems analysis, including remote sensing, basin modelling and hydrocarbon migration, leakage and seepage. He has also consulted to the Federal Government.
 
 Dr O'Brien worked for Geoscience Australia (1985-2001), where he was the Research Group Leader in the Marine Environment & Offshore Petroleum Group, as a research fellow and consultant at the University of Adelaide (2001-2003), as the Energy Geoscience Manager at Geoscience Victoria (2006-2011) and as the Chief Geoscientist for NOPTA between 2012 and 2018.
 
 Geoff has been awarded multiple awards for his efforts, including two APPEA Best Technical Paper Awards and a WABS Best Presented Paper Award. Dr O'Brien has published over 100 papers, a similar number of abstracts and his work appeared on the front cover of Nature.

 He has a vast knowledge of Australia's sedimentary basins and their petroleum potential and over the last 15 years has become increasingly involved in the CCS sector. A passion of his is the development of tailored and targeted CCS work programs that relate specifically to the ultimate regulatory requirements, thereby facilitating the pathway to storage - and saving vast amounts of money for project proponents.
