PESA QLD: Lunch, 20 March : What happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts) – Dr Julie Pearce

PESA technical lunches are back for 2025!

PESA Queensland welcomes Dr Julie Pearce to present a technical luncheon on What happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts)

The Technical Lunch will be held at the Brisbane Hilton Hotel, (Room TBC).

For detailed directions, see explanation below.

Please note the Early Bird ticket pricing cut-off times described below.

Presentation Abstract:

Carbon dioxide geological storage is one option to enable Australia to reach net zero. Several carbon storage demonstration sites are undergoing feasibility studies and environmental impact assessment internationally and in Australia. Very recently CO2 storage in the Surat Basin gained a lot of media and political attention – the QLD government has now put a ban on CCS in the geographical extent of the QLD Great Artesian Basin (and below it). The reservoir that was being assessed is in a deep (~2300 m), brackish, unpotable part of the Precipice Sandstone. However, the broader formation is an aquifer of the GAB, therefore stakeholders were sensitive to potential environmental impacts. The previous demonstration site that underwent assessment was further north in the shallower part of the Precipice Sandstone (~1200 m). In that Glenhaven site the West Wandoan 1 well was drilled for the feasibility study, and the reservoir had fresh groundwater. This presentation details part of the experimental and field sampling components of the underlying research, including CO2-water-rock geochemical reactions, metal mobilisation, and creation of a reactive transport model.
