Bonaparte CO2 Storage Project
A study of the Petrel Sub-basin (Bonaparte Basin), offshore Northern Territory (Figure 1), has found that the sub-basin is suitable for the geological storage of CO2 (Figure 2). The study, which was funded through the National Low Emissions Coal Initiative, targeted the Petrel Sub-basin because of its proximity to emission intensive industries and favourable geology for potential geological CO2 storage. Geological and geophysical analysis identified two saline reservoir-seal pairs that have a total effective CO2 storage capacity of 15.9 gigatonnes (300 trillion cubic feet).
The study report Regional assessment of the CO2 storage potential of the Mesozoic succession in the Petrel Sub-basin, Northern Territory, Australia: summary report. Record 2014/11 summarises the results of the analysis, and contains supporting appendices, 18 well composites and data packages.
Data packages from the study can also be ordered. These comprise the following:
Petrel Sub-basin Seismic Survey (GA336): High resolution multichannel seismic data were acquired between 3 May and 24 June 2012 by the MV Duke (Figure 3). The seismic data have been processed to enhance the stratigraphy in the shallower (<1000 m below sea floor) formations. Seismic and associated datasets are available for download and include:
- 4091 line kilometres of seismic reflection
- 8000 line kilometres of multibeam swath bathymetry
- Chirper sub-bottom profiler data
- Post-stack depth migration and 2D simultaneous inversion analysis of four key lines of GA336 seismic survey
Petrel Sub-basin Marine Survey (GA335): The marine survey, conducted in collaboration with the Australian Institute of Marine Science (AIMS), was completed in May 2012 (Figure 4). A post-survey report is available for download and supporting datasets include:
- 5300 line kilometres of multibeam swath bathymetry
- 655 line kilometres of sub-bottom profiler data
- Underwater video and still images
- Seabed sediment and biological samples
Petrel Sub-basin geological data package: A series of datasets were acquired to support the findings published in the Geoscience Australia Record 2014/11.
- ArcGIS packages
- Mineralogical, petrophysical and pore properties analysis
- Hydrodynamic analysis
- Geological and simulation model data
- Series of key well composites and well sections
