Published on

The Groundwater and Storage interactions project arose out of a meeting on the shoulder of the Greenhouse Gas Technologies Conference in Amsterdam in 2010. It was decided to concentrate initially on the Australian Flagships projects. On 3 May 2011 Australian researchers and government agencies met and presented their work to date.

In these slides the Queensland Carbon Geostorage Initiative present on Groundwater Research Projects

  16. 16. Current and Future Requirements • New data is the key • Reservoir and seal mineralogy at depth • Hydrochemistry – accurate minor and trace element compositions • Improved kinetic rate constants – asymmetry between precipitation and dissolution • Empirical confirmation of modelled scenarios • Hydraulic data – porosity/permeability/relative permeability • Modelling studies • Improved geological frameworks • Sequence stratigraphic interpretation for regional correlation • 3D fluid flow • Vertical hydraulic relationships • Hydraulic significance of faults • Reactive transport • Geomechanics© The State of Queensland, Department of Employment, Economic Development and Innovation, 2010 16
