Geological Storage of Carbon Dioxide (CO2CRC) Project

This project is Geoscience Australia's contribution to the core program of the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC). The CO2CRC is one of the world's leading research organisations developing technologies and the science required for carbon dioxide (CO2) capture and geological storage (CCS). Phase two of the CO2CRC commenced in July 2010. The Storage Program within the CO2CRC addresses a wide range of questions relating to areas such as CO2 monitoring, the nature of deep aquifers and rock mechanical behaviour in storage formations and fluid-rock interactions imposed by high CO2 concentrations.

Geoscience Australia researchers lead the following projects:

  • Reactive reservoir rocks and their impact on CO2 storage in terms of injectivity and containment
  • seal geomechanics and potential for CO2 leakage.

Geoscience Australia researchers also contribute to the following projects:

  • The residual gas saturation test at the CO2 storage demonstration site (Otway, Victoria) 
  • improved monitoring and verification.

Achievements in the Financial Year 2011-12

  • The residual gas saturation test was completed successfully at the Otway CO2 storage demonstration site wherein GA was leading three test sequences. Results will be presented at the international conference on Green House Gas Technologies (GHGT-11, Japan) in November 2012.
  • A manuscript by P. De Caritat and colleagues on groundwater monitoring data before and after the injection of approximately 65,000 tonnes of CO2 at the Otway demonstration site in 2008-2009 has been published in the journal Applied Geochemistry.
  • A manuscript by E. Tenthorey and colleagues on modelling geomechanical implications of gas injection and abstraction in the Iona gas reservoir has been completed and submitted for peer-review.
