Stratigraphic correlation in kilometres-thick Triassic fluvial successions of the Carnarvon Basin, Northwest Shelf (NWS), Australia, has traditionally been hindered by a lack of continuous seismic events, low biostratigraphic resolution and the pract...

An integral component of the Chevron operated Gorgon Project is the proposal to dispose of reservoir carbon dioxide by underground injection into the Dupuy Formation below Barrow Island. As part of this project, Chevron has undertaken a new assessmen...

This paper documents a detailed tectono-stratigraphic analysis of five merged 3D seismic surveys that cover the greater part of the Exmouth Sub-basin in the Northern Carnarvon Basin on the North West Shelf of Australia. ...

This plenary paper reviews industry trends* and Woodside‟s achievements during the decade 2002 to end 2011 (the period since the last dedicated WABS Symposium)....

This study focuses on the stable carbon (δ13C) and hydrogen (δD) isotopic compositions of bulk, saturated and aromatic hydrocarbons in 19 Paleozoic marine crude oils from the Canning Basin, Western Australia....

Australia’s North West Shelf (NWS) has been the premier hydrocarbon exploration and production province for over 30 years. Despite the large number of geological studies completed in this region, numerous geological questions remain to be answered ...

Seismic profiles in the northern Canning Basin reveal a major WNW-oriented strike-slip fault zone in the Fitzroy Trough. The zone bisects the trough and was generated during the Triassic–Jurassic Fitzroy Transpression. It contains likely flower str...

For many basins along the western Australian margin, knowledge of basement and crustal structure is limited, yet both play an important role in controlling basin evolution. To provide new insight into these fundamental features in the Browse Basin, w...

High-resolution chronostratigraphic correlations are integral to meaningful stratigraphic frameworks in depositional systems, but may be difficult to achieve due to biostratigraphic limitations and geological complexity. In steep-sided carbonate plat...

As part of the National CO2 Infrastructure Plan (NCIP), Geoscience Australia is undertaking evaluation of the Vlaming Sub-basin, offshore Western Australia, for the long-term storage of CO2. The Early Cretaceous Gage Sandstone is a quality reservoir ...

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...
