Inpex is on the hunt for potential carbon capture and storage locations in the Bonaparte Basin off the coast of WA.
Inpex is the operator of the Bonaparte carbon capture and storage assessment joint venture, which also includes TotalEnergies and Woodside Energy.
The joint venture is currently undertaking a 3-year subsurface appraisal program in the Bonaparte Basin. To date the appraisal program has included the acquisition and interpretation of seismic survey data and the drilling of two wells for the purpose of data collection. In parallel with the appraisal programme, Inpex is conducting a preliminary assessment and selection of a suitable development concept, including preliminary facility designs for the transport and sequestration of carbon dioxide.
To inform the design and location of the potential future development, Inpex has requested permission from NOPSEMA to undertake a range of geophysical and geotechnical surveys.
The scope of the environment plan covers geophysical and geotechnical survey activities within the proposed survey area and adjacent Commonwealth waters.
Activities include:
Geophysical survey scope comprising of:
• multi-beam echo-sounder and LiDAR for bathymetry
• side scan sonar
• sub-bottom profiling and imaging
• magnetometer.
Geotechnical survey scope comprising of:
• seabed grab sampling (box core)
• geotechnical piezocone penetration tests
• geotechnical borehole, and vibrocore, and gravity cores.
Collection of marine baseline data.
The Bonaparte carbon capture and storage project is intended to become a large-scale multi-user carbon storage hub located on the doorstep of Asia.
The joint venture is aiming to inject the first carbon dioxide into the project in 2030.
