3D Geological Modelling and Petroleum Prospectivity Assessment in Offshore Frontier Basins using GOCAD: Capel and Faust Basins, Lord Howe Rise

As part of Geoscience Australia's analysis of the Capel-Faust basins this report summarises the construction methodology and the resulting geological and prospectivity implications of the Capel-Faust 3D geological model. The Capel and Faust basins are located over the northern part of the Lord Howe Rise, a large offshore frontier region composed of a number of rift basins with unknown petroleum prospectivity. Geoscience Australia has been undergoing a program of data acquisition in this area over a number of years, yet most dataset coverage remains regional with little well control. Given the diversity of acquired data, the comparative sparseness of coverage (despite the new data acquisition) and the structural complexity of basins, effective data integration and analysis methods were essential in the Capel-Faust region. By using the 3D visualisation and modelling environment provided by GOCAD, the diverse datasets were captured, processed and interpreted to create an integrated basin model that enabled key geological and prospectivity questions to be answered.

Wiluna 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD.

MRTAS Offshore SW Tasmania 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 MRTAS Offshore SW Tasmania magnetic grid geodetic has a cell size of 0.00167 degrees (approximately 161m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2008 by the TAS Government, and consisted of 26548 line-kilometres of data at 800m line spacing and 95m terrain clearance.

Geology of the Wiso Basin, Northern Territory

The Wiso Basin, a structural downwarp in the central western part of the Northern Territory, contains a sequence of near-horizontal Middle Cambrian to ?upper Palaeozoic sedimentary rocks. It is continuous with the Daly River Basin to the north, and with the Georgina Basin to the northeast and possibly the southeast. Most of the basin surface is a flat plain which has developed in semi-desert country. Some of the rock sequences of the basin are imprecisely known because of poor outcrop. Cambrian to Ordovician sediments include five mappable rock units; disconformities and unconformities separate some units and may occur within the less well known ones. The basin sequence is thin in the northern and central parts (generally less than 500 m), but thickens southwards into the Lander Trough (up to 1000 m); farther south, the Cambrian to Ordovician sediments are faulted against the Arunta Block on the southern margin of the basin. ?Upper Palaeozoic sandstone overlies these rocks in the Lander Trough and transgresses the faults. Almost flat-lying Mesozoic sediments overlie the northern part of the basin, and these, together with the older rocks of the basin, were extremely weathered during the formation of a laterite soil profile in Late Cretaceous or Early Tertiary time. A thin veneer of Cainozoic sediments, including extensive sand plains and dunefields, has since formed over the basin, and a sparse vegetation of spinifex and light scrub has developed. Few mineral occurrences have been recorded in the basin, but supplies of water are present in the sediments, and the possibility of hydrocarbon accumulations in the Lander Trough cannot be dismissed.

AUSGeoid98 v.1.0 data files:  (sl56-09)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Geology of the Sydney Basin - A Review

The Sydney Basin extends for 380 km along the east coast of New South Wales south of latitude 32Â°S, and has an onshore area of about 36 000 km2 . About 4800 m of Permian and Triassic sedimentary rocks are preserved in the basin which lies between the New England and Lachlan Fold Belts. The study of the Sydney Basin by the Sedimentary Basins Study Group of the Petroleum Exploration Branch of the Australian Bureau of Mineral Resources was undertaken in co-operation with the New South Wales Department of Mines, who prepared a 1:500 000 geological map (PI. 1). The study has required constant exchange of ideas and information with petroleum exploration companies and the Department of Mines. In addition to the authors of this Bulletin the following members of the Sedimentary Basins Study Group since late 1966 have contributed to the study: D. J. Forman, M. A. Reynolds, K. G. Smith, R. Bryan, A. R. Jensen, P. J. Alcock, P. J. Hawkins, R. B. P. Pitt, S. Ozimic, J. I. Raine, K. Rixon, and B. G. West.

Source Rock Time Slice Maps: Offshore Northwest Australia, 2004

Maps, plots and data sheets of average source rock richness, quality and maturity for five Mesozoic time slices are presented for offshore Northwest Australia (Carnarvon to Arafura basins). These maps/data facilitate regional assessment of the source rock potential of the region, and provide a framework for future exploration of the region's petroleum systems.
The maps were compiled at a scale of 1:3 million, and are supplemented by two-way-time isopach maps for each time slice derived from interpretation of Geoscience Australia's regional seismic grid of the area (approximately 35,000 line km).  Age vs TOC, S2 and HI, and source rock crossplots were also compiled from screened raw Rock-Eval pyrolysis data and displayed as inserts in the maps.  The maps and open-file data used in the compilation of the maps can be viewed directly, or printed as a hard copy.
