The Australian Government, through the Department of Industry, Innovation and Science, routinely funds Geoscience Australia to acquire pre-competitive data to support prospectivity assessments of various offshore basins. As part of the Australian Government's National CO2 Infrastructure Plan (Carbon Storage Taskforce 2009), a marine seismic reflection survey, Gippsland Basin Infill 2D Marine Seismic Survey - GA0352, was undertaken in the offshore southern margin of the Gippsland Basin to investigate potential sites suitable for CO2 geological storage (Langford, 2016).

The Canning Basin is a large intracratonic basin in Western Australia that remains one of the least explored Paleozoic basins in the world. Recent resource assessments have renewed interest in the basin, in particular for unconventional gas within Ordovician organic-rich shales, although these proposed plays remain untested. Exploring for the Future (EFTF) is a program dedicated to exploring Australia’s resource potential and boosting investment. Launched in 2016 with $100.5 million in funding from the Australian Government, it initially focused on northern Australia. Geoscience Australia and the Geological Survey of Western Australia collected new, pre-competitive datasets in the frontier Kidson Sub-basin to better understand its energy resource potential. Here we present an overview of the regional petroleum systems with a focus on the modelled Ordovician section within the Kidson Sub-basin and Barnicarndy Graben (previously Waukarlycarly Embayment). Three Larapintine petroleum systems are recognised in the Ordovician (L2), Devonian‒earliest Carboniferous (L3), and Carboniferous (L4) successions of the Canning Basin. Integration of petroleum systems with interpretation of the Kidson Sub-basin seismic survey 18GA-KB1 shows that the Ordovician section is extensive, and hence, the Larapintine 2 Petroleum System is of most exploration interest across this frontier region. Ordovician organic-rich units are known within the Nambeet (Tremadocian–Floian), Goldwyer (Dapingian–Darriwilian) and Bongabinni (Sandbian) formations; however, only Nambeet and Goldwyer source rocks are considered to be present within the Kidson Sub-basin. Oil and gas shows occur within Ordovician and Silurian reservoirs, of which many are sub-salt. The range in the geochemical profile of shows from Goldwyer, Nita and Sahara reservoirs implies generation from numerous source units within the Goldwyer and Bongabinni formations. The origin of oil and gas shows within the Nambeet and Willara formations, including those in Patience 2 in the Kidson Sub-basin, is unknown but imply the presence of multiple lower Ordovician source units and include the Nambeet Formation. Within the Kidson Sub-basin, Kidson 1 is located closest to the main depocentre, whereas other wells are proximal to shelves and margins. In general, these latter wells return discouraging hydrocarbon potential pyrolysis parameters as a consequence of their sub-optimal location for source rock development and thermal maturation history. Kidson 1 penetrates the Goldwyer Formation and has TOC contents that are considered more representative of source rock richness (although diesel contamination is present) within the depocentre. Data paucity is the key limitation in resource evaluation for the Kidson Sub-basin, as such, an evaluation with volumetrics is not possible. 1D petroleum systems models of ten wells located in either the Kidson Sub-basin, Willara Sub-basin or Barnicarndy Graben were constructed to resolve whether potential source rocks were capable of hydrocarbon generation. The models demonstrate maturation of Ordovician source rocks resulting in near-complete transformation during Permian to Triassic deposition and burial. A 2D petroleum systems model constructed along the regional 2D seismic line 18GA-KB1 predicts full maturation of Larapintine 2 source rocks in the deeper parts of the Kidson Sub-basin. Expulsion and migration is considered to have taken place during the Permian‒Triassic, with potential accumulations trapped by evaporitic and fine-grained units of Ordovician and Silurian age.

Historical data concerning the operations and findings at the Coorabin coalfield between 1915 and 1937 has been compiled in this report.

The map and supporting booklet (the key) are based on information held by the State and Territory Departments of Mines and the Commonwealth Department of Industry, Science and Resources. The map is published annually at a scale of 1:5 000 000 and supports the Commonwealth Government's offshore petroleum exploration area release program. The map includes all available information up to May 2003. The key (booklet) accompanying the map lists the relevant title numbers, the title holders, areas of the titles and expiry dates, by State and Territory. Also included is information on petroleum exploration permits, licences, leases and production licences in offshore areas under the jurisdiction of the relevant State and Territory petroleum acts, and offshore areas under the Commonwealth Petroleum (Submerged Lands) Act.

This dataset contains the 31 areas released as the 2013 Offshore Petroleum Acreage Release

Promotional flyer comprising map showing petroleum exploration permits and current and proposed gazettal areas for acreage release. map is supplemented by short information (text) about geological aspects of release areas and summeries of Austrlaia's oil and gas production levels.

The data lists the occurrence of selected (only zonally or environmentally significant species of foraminfera were recorded) species of planktic and benthic foraminfera in each dredge sample, denoting that the species is present.

These data are a brief description of the sampling (cores, grabs, and dredges) that occurred on Geoscience Australia survey 265 in March 2004 in the visinity of the Bremer sub-basin, offshore southwest Western Australia on CSIRO Marine's research vessel the Southern Surveyor. Co-ordinate location, recovey and a few basic descriptions were recorded whilst on the vessel and have been captured in these datasets.
