Offshore appraisal well

The CarbonNet Project is planning for its next field activity, the drilling of an offshore appraisal well (OAW) at the Pelican site in Commonwealth waters in late 2019/early 2020.

Appraisal wells have been drilled by the oil and gas sector in Bass Strait for more than 50 years. They are used to verify the properties of rock layers below the seabed.

Rock samples from CarbonNet’s appraisal well will allow scientists to validate existing geoscience models and to confirm the properties of the rock which will form the barriers to hold the stored carbon dioxide (CO2) in place.

The Environment Plan for this activity was approved by the regulator, National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA), in April 2019. To view the Environment Plan Summary, visit NOPSEMA.


A jack-up rig will drill to a depth of about 1,500m below the sea bed (figure 1). Drilling is expected to take up to 60 days to complete.

The activity is being managed by AGR (Australia) Pty Ltd as the Drilling Management Contractor for CarbonNet. AGR has drilled over 40 offshore wells in Australia.

The OAW will be located approximately 8 km offshore in Commonwealth waters. The proposed location is shown on the map below.

OAW scheduling and duration is dependent on fair sea state conditions and drilling rig availability.

Drilling is currently planned for late 2019/early 2020. The exact timeframe is yet to be determined.
