Browse Reservoir CO₂ Geosequestration

This project was removed from the Institute’s LSIP listing in August 2012 after its proponent confirmed that CCS plans at the Browse LNG development are not currently being progressed further.

While Browse Joint Venture has undertaken geosequestration evaluation studies for the proposed James Price Point development in line with the Browse Retention Lease conditions, these studies have concluded that geosequestration is not currently commercially viable. Geosequestration will however be maintained as a potential option for managing carbon from the Browse LNG Development should it become economically and technically viable during the life of the project.

Location: Western Australia, Australia.

Proponents: Woodside Energy Ltd (Operator), on behalf of the Browse Joint Venture

Technical aspects

• The Browse LNG development will produce around 12 million tonnes per annum (Mtpa) of liquefied natural gas (LNG).
• The natural gas (reservoir) feedstock contains around 10 per cent carbon dioxide (CO₂).
• Geosequestration had been evaluated as one option for managing the reservoir-related CO₂.

Key Deliverables

• Front-end engineering design (FEED) studies began in early 2011.
• Start-up for the main LNG system is targeted at 2017.

The application of CCS to manage CO₂ was considered, among other options, by the proponent. A wide screening of suitable storage sites and a more detailed evaluation of high ranked site options have been carried out. This detailed evaluation included static and dynamic modelling for each site to understand the potential movements of reservoir CO₂.
