Discusses reasons to use the Australian Stratigraphic Units Database (ASUD), and new features of the web query page and reports

A short article describing the outcomes of the Tasman Frontier Petroleum Industry Workshop held at Geoscience Australia on 8 and 9 March 2012.

Magnetic field interpretation is not an alternative to palaeomagnetic methods of recovering remanent magnetization information, both because it deals with the resultant of induced and remanent magnetizations and because confidence in recovered magnetization directions cannot match than provided by direct palaeomagnetic measurement. Nevertheless, magnetic field interpretation is highly complementary to palaeomagnetic studies. Palaeomagnetism provides detailed information from small, localised samples whereas magnetic field interpretation provides estimates of the bulk magnetization of substantial volumes (which may be completely buried and un-sampled by boreholes). Without palaeomagnetic and rock magnetic studies much of the geological information latent in magnetic field measurements cannot be accessed, and without the coverage of magnetic field data the extents and relationships of subsurface magnetization events revealed by palaeomagnetic studies cannot be fully mapped.

This data catalogue was compiled for use by memebers of the Central Gawler Gold Sub-project. The compilation forms the basis of a continuing data location and stocktaking exercise. This data catalogue consists of data collected from known digital records at PIRSA and GA for the Central Gawler Gold region in Central South Australia. Much of the data was sourced from PIRSA's South Australia DVD dataset with additional information from PIRSA and GA's coporate databases and PIRSA's open file records. Information on non-digital data was assembled from PIRSA's pre 1997 open file records and through communications with the various researchers who have work in the region.

This publication is the successor to Oil and Gas Resources of Australia 2001 and continues as the definitive reference on exploration, development and production of Australia's petroleum resources. OGRA 2002 provides the background for much of the advice on petroleum resources given to the Australian Government.

This publication is the successor to Oil and Gas Resources of Australia 2002 and continues as the definitive reference on exploration, development and production of Australia's petroleum resources. It covers exploration, reserves, opportunity for growth of oil and gas resources, development, coalbed methane resources, production, crude oil and shale oil and supporting information and statistics. It includes a forecast of Australia's crude oil and condensate production from 2004 to 2025, and sustainability indicators for petroleum resources. Information on Australia's petroleum data availability is also included and an estimate of Australia's undiscovered oil and gas potential and a review of developments in geological sequestration of carbon dioxide. The Appendices describe wells drilled and seismic surveys carried out in 2003. There is also a chronological listing of offshore and onshore oil and gas discoveries to 2003 listings of all petroleum platforms and pipelines, and a map showing all Australian petroleum exploration and development titles, with a key of title holders and interests as at March 2004. OGRA 2003 provides the background for much of the advice on petroleum resources given to the Australian government and is a key source for petroleum exploration, production and service companies, petroleum engineers and geologists, energy analysts, stockbrokers and share investors.

The seismic stacking velocity data in the Great Australian Bight are a useful dataset for calculating depths and sediment thicknesses. This work presents time-depth relationships computed from an unfiltered stacking velocity database and compares these with depths from sonobuoy P-wave velocities and exploration well sonic logs. The comparison suggests that a total sediment thickness over-estimate for the Ceduna Sub-basin of about 15% can be expected from the depths derived from stacking velocities. On the other hand, for sediment thickness calculations down to ~4 s two-way travel time below sea floor, stacking velocity data give comparable depths to those obtained from the wells' sonic logs. A piece-wise formula is offered which scales the time-depth function for the Ceduna Sub-basin in order to compensate for the depth overestimate inherent in using stacking velocities to calculate total sediment thickness. Megasequence boundary depths are calculated for the Ceduna Terrace to further illustrate data quality.

This record represents a summary of the specifications of most surveys held in the National Airborne Geophysic Database (updated from 2001 when the fifth edition of this record was released).
