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, Dr Monica Campi, GeoScience Victoria, Presents on Victorian CCS – Groundwater issues

Presentation Notes
The three offshore areas are currently still open for tender applications (act has not been finalised, unclear when the closing date for these areas will be,, one factor may be timing of seismic processing) The Victorian proposal for establishing CCS is based on the staged development of a CCS network over the next 10 years and beyond. CarbonNet is the Victorian Government’s blue-print for the staged development a multi-user network which serves the Latrobe Valley and provides common-user infrastructure and storage. This network will leverage: - projects under the State’s ETIS grants program - other CCS initiatives and investment from the private sector - structuring options which provide a pathway to commerciality. Indicatively, through this network, Victoria could sequester 3-5 million tonnes of carbon dioxide by 2015-18 (depending on storage availability), potentially scaling up to perhaps 20 million tonnes from 2020, if the carbon price is sufficient.

Vic DPI CCS-Groundwater Projects• Regional hydrodynamic modelling of the Gippsland Basin (CSIRO)
• Compartmentalisation of the Latrobe aquifer system (DSE/CSIRO)
• Reservoir and Seal Mineralogy• To lead into future Fluid-Rock-CO2 interactions studies
Presenter
Presentation Notes
CSIRO hydrodynamic study – development of freshwater wedge and salinity, study of fluid flow, head data and recharge information from pre-production, today and in injection scenarios. Compartmentalisation study – fault risking and new fault surfaces across the basin (Latrobe Valley into central deep), including fault reactivation to go into hydrodynamic model.
Conceptual flow model – Gippsland Lakes area
Presenter
Presentation Notes
Early modelling Current modelling that CSIRO is doing is variable density hydrodynamic modelling to take into account the varying salinity across the basin. To set up a static model to incorporate variable density – next phase will use this model to develop a dynamic model for injection simulations

Preliminary salinity for the Gippsland BasinData from DSE waterbores and CSIRO PressurePlot (wells)
Presenter
Presentation Notes
Data from the DSE groundwater monitoring bores has not been QC’d, and has little information about the depth of the sample Lake Wellington Depression shallow groundwater system appears to be isolated from the Seaspray Depression, as the high salinities found in the Macalister Irrigation District are not seen to the south across the Rosedale Fault System. This indicates that it is likely that the Rosedale Fault System is sealed to fluids at shallow depths, although it could be also be topographical, and controlled by the Baragwanath Anticline Higher salinity values along the coast are likely to be shallow invasion by seawater. This is the driver for the DSE compartmentalisation study – where we can overlay faults and head information
New fault surfaces for the Gippsland Basin
Presenter
Presentation Notes
This new fault model will be incorporated into the hydrodynamic model to better understand the compartmentalisation of the Latrobe Aquifer System
‘Need to knows’:• Fluid-rock-CO2 interactions
• Mineral reactivity• Salinity dependent
