Geoscience Australia is currently conducting a study under the National CO2 Infrastructure Plan (NCIP) to assess suitability of the Vlaming Sub-basin for CO2 storage. It involves characterisation of the potential seal, the Early Cretaceous South Pert...

The margins of the Canning Basin of Western Australia were the loci for extensive carbonate accumulation throughout Middle to Late Devonian times. The irregular coastline of the Lennard Shelf produced a variety of depostional settings, including isol...

The 2011 discovery of the Ungani oil field by Buru Energy has driven a far-reaching change in perceptions of the prospectivity of the Canning Basin of Western Australia. Previously the basin had been portrayed as ‘difficult’, with a number of pot...

The Gorgon Field, a giant gas accumulation discovered in 1980, remained undeveloped for over three decades due to challenging subsurface and commercial factors. Situated in the Northern Carnarvon basin in 200–300 m of water, the Gorgon Field lies 1...

The U–Pb age spectra of detrital zircons separated from sandstone were determined for twelve Canning Basin samples, two western Officer Basin samples, and one basement sample from the centre of the Canning Basin. The basement sample has an early Ne...

Questions regarding heterogeneity and architecture of reefal carbonate platform systems may be resolved by wellconstrained chronostratigraphic frameworks, developed from the integration of multiple independent signals in the rock record. This makes p...

The Bonaparte Basin is marked by the development of a wide (ca. 630 km) continental shelf where carbonate and siliciclastic sediments accumulated during the Late Pliocene and Quaternary (ca. 3.5 Ma BP onwards). This unusually large platform is associ...

In 2012, Geoscience Australia carried out marine surveys in the Vlaming Sub-basin (Perth Basin; GA0334) and Petrel Sub-basin (Bonaparte Basin; SOL5463). The purpose of these surveys was to gather pre-competitive geophysical and biophysical data on th...

The Early to Middle Jurassic Plover Formation in the Browse Basin hosts reservoirs currently targeted for gas exploration and development. Integration of core-based sedimentology, igneous petrology, borehole image and wireline log analysis, with bios...

Late authigenic pyrite cementation is common to abundant in the Middle Jurassic Laminaria and Plover Formation sandstone in numerous wells on the Laminaria High and in the Vulcan Sub-basin of the northern Bonaparte Basin. Pyrite cementation developed...

The Mesozoic and Cenozoic of the North West Shelf can be subdivided into 18 broad stratigraphic intervals that show a remarkable degree of geological similarity from basin to basin. These intervals are termed “regional play intervals” and are rel...

The southwest margin of Australia is a complex and relatively poorly studied offshore continental region that includes the Perth and Mentelle basins. Plate reconstruction models, in conjunction with regional seismic and potential field data, demonstr...

As high-quality 3D seismic data has become widely available, stratigraphic interpretation has significantly improved our ability to predict the subsurface distribution of lithologies. Stratigraphic interpretation of seismic data involves the integrat...

Emphasis has been traditionally placed in characterising ichnological signatures of the classical end members of the genetic ternary plot, namely river-, wave- and tide-dominated deltas. However, recent years have witnessed progress in the understand...

A number of sub-parallel, rhomboidal basinal features identified along the northwestern coastline of Western Australia occur in areas where present-day seismicity indicates strike-slip failure mechanisms dominate. This paper examines the rhomboidal f...

The Early Cretaceous Birdrong Sequence (S. tabulata - P. burgeri) represents the final episode of coarse clastic sedimentation across the Barrow Sub-Basin prior to transgression and the deposition of the Mardie Greensand - the 'last gasp' of the Barr...

Geoscience Australia’s Onshore Energy Security Program (OESP, 2006-2011) provided precompetitive geoscientific data and detailed assessments of the potential for onshore energy resources, including oil, gas, geothermal, uranium and thorium. With st...

Many rifts and passive margin basins are characterised by dykes and sills that intrude the both pre-rift and syn rift strata. In the southern part of the northern Carnarvon Basin sills and dykes are well imaged in a number of 3D seismic surveys. This...

The Australian Government will complete a regional study of the greenhouse gas storage prospectivity for the southern Bonaparte Basin, offshore Northern Territory. The study identified a large storage capacity within a safe and secure stratigraphic s...

The Timor accretionary wedge developed in response to the Neogene collision of the Australian Plate with the Banda Arc. New 2D and 3D seismic data acquired offshore Timor-Leste have been used to investigate the sedimentary and structural features of ...

Deltaic settings are highly complex with regard to the interaction of wave, river and tidal processes. As benthic organisms respond differentially to these processes due to a variety of stress factors, this results in complex faunal behavior. This pa...

Although evidence for a major gas resource in the onshore Canning Basin was present in wells drilled as early as the 1960s, the opportunity to develop these resources was not recognised until increasing oil and domestic gas prices stimulated a resurg...

Long offset regional 2D seismic surveysrecently acquired by PGS across the Timor/Tanimbar Trough have provided previously unseen detailed imaging of the continent/arc collision zone between northern Australia and Indonesia.New broadbandseismic data w...
