AusSeabed Bathymetry Compilations Coverage Database

The AusSeabed Bathymetry Compilations Coverage Database contains polygon extents of bathymetry data acquisitions along with identifying attributes and contact details where the data is not held by Geoscience Australia.  It is an important scientific resource that identifies data spanning coastal, continental shelf and deep sea locations. 

This dataset is live and will continue to be augmented as coverage details are supplied from AusSeabed collaborators who wish to share their knowledge of data availability to the broader marine community. The database is updated regularly and is made available via the AusSeabed Marine Data Portal using OGC compliant web services. Compilations have been generated from one or more Survey/Data Acquisitions by a wide range of organisations and countries, both inside and outside Australia's marine jurisdiction, using multiple systems and for various applications. Compilation coverages are published where the polygon extents intersects with Australia's marine jurisdiction, including the Australian Antarctic Territory.  Each polygon in the layer contains metadata describing compilation details. 
Note that polygons may not be representative of the true survey extent due to the data gridding process. 

Please contact us at ausseabed@ga.gov.au if you wish to contribute coverage information to the database.

The potential for residual oil zones to maximise CO2 storage capacity in Australian petroleum provinces

Residual oil zones (ROZs), with or without CO2-enhanced oil recovery, could potentially increase the storage resources associated with depleted field CO2 storage projects while capitalizing on existing infrastructure, local geological knowledge and a ready supply of CO2. Under the Australian Government’s former Exploring for the Future program (2016-2024), we identified and characterized ROZs in strategic hydrocarbon provinces in central-eastern Australia using a new integrated workflow that primarily relies on petrophysical analysis. ROZs were found to occur below the main oil column in fields across the study area, mainly in the Jurassic reservoirs of the Cooper and Eromanga basins, and particularly within the Hutton-Birkhead and Namur-McKinlay oil plays of the Eromanga Basin. Most are thin (less than a few tens of meters), with low residual oil saturation (<10%). Multiphase compositional flow modelling conducted on a ‘typical’ Australian ROZ, based on the real ROZs identified in the Hutton Sandstone, was used to estimate CO2 storage efficiency and additional oil production potential under a range of CO2 injection scenarios. Modelling shows that CO2 injection under fully miscible conditions can efficiently mobilize and recover significant amounts of residual oil, and that CO2-oil interactions increase the density and viscosity of CO2, enhance CO2 sweep efficiency and lateral flow, and improve overall storage efficiency. We found that the maximum amount of CO2 storage can be achieved with a gravity stable flood resulting from injection of CO2 at the top of the reservoir. The extent of these effects depends on the quantity and spatial distribution of residual oil in place, the miscibility of CO2 at reservoir conditions, and well configuration. Our study shows that while additional oil recovery potential is relatively low, and not comparable to the billion-barrel ROZs that are being produced in other parts of the world, the good reservoir quality rock below the deepest occurring conventional oil in many of the fields, particularly in the Hutton and Namur Sandstones of the Eromanga Basin, appears to be a promising target for CO2 storage.

Gawler Craton Mineral Promotion Project Plan, 2000-2004

The Gawler Craton has been defined as that region of South Australia where Archaean to Mesoproterozoic crystalline basement has undergone no substantial deformation (except minor brittle faulting) since 1450 Ma (Figure 1; Thomson, 1975; Parker, 1993; Daly et al, 1998). The eastern and southeastern boundaries conventionally are defined by the Torrens Hinge Zone (THZ), although Gawler Craton basement that was deformed during the Delamerian Orogeny is known to the east of the THZ (eg Barossa Complex, Peake and Denison Inliers). The southern boundary corresponds to the inboard edge of the continental shelf. The Gawler Craton and the East Antarctic Craton are rifted segments of the Mawson Continent (Fanning et al, 1995). Western, northwestern and northern boundaries of the Gawler Craton are defined by the faulted margins of thick Neoproterozoic and younger basins.
As a consequence of the extensive surficial and sedimentary basin cover, the level of understanding of the craton's geology and prospectivity are limited in comparison with most other Australian Archaean and Proterozoic cratons. Application of high-resolution regional aeromagnetic surveying during the mid-1990s (South Australian Exploration Initiative - SAEI), for the first time allowed an integrated interpretation and synthesis of the geology of the craton (Fairclough and Daly, 1995a; Fairclough and Daly, 1995b; Schwarz, 1996).
A revised interpretation of the tectonic evolution of the Gawler Craton incorporating SHRIMP U-Pb geochronology, was presented by Daly et al (1998). Three principal orogenies have been proposed: The Sleafordian Orogeny (peak metamorphism at ~2420-2440 Ma), the Kimban Orogeny (KD1-KD2-KD3: 1845-1700 Ma), and the Kararan Orogeny (~1650 Ma and 1565-1540 Ma). It has been suggested that the Kararan Orogeny in the western and northern Gawler Craton represents the continental collision of the 'eastern proto-Yilgarn' and the Mawson Continent (Daly et al, 1998). The geodynamic significance of the Sleafordian and Kimban Orogenies is unclear. Subdivision of the Gawler Craton into tectonic domains has evolved as further information has become available (Figure 1; eg Parker, 1993; Flint and Parker, 1982; Drexel et al, 1993; Teasdale, 1997). In general the definition and nature of the domain boundaries are not well understood - addressing this problem is a key objective of the Gawler Craton Project. The resultant framework will be important for assessing prospectivity because the ore-forming systems are products of crustal-scale processes that may vary between tectonic domains.
The contents of this GA Record were written in 2000, and were presented on the Gawler Project website prior to the publication of this GA Record.

Medusa Banks Port Keats magnetic grid geodetic

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Medusa Banks Port Keats magnetic grid geodetic has a cell size of 0.001 degrees (approximately 109m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 68378 line-kilometres of data at 500m line spacing and 100m terrain clearance.
