Australian Petroleum Blocks 2014a - Geodatabase

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts.
The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset 2014 (AMB2014a). This version contains a number of technical amendments made on the basis of user feedback. These include:
-  Removal of lease AC/P17
- Harmonisation of maritime boundaries, scheduled area and graticular block datasets in block SC51
The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.
The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset.
The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.
Existing production licences AC/RL4, and AC/RL5 are included in the dataset.
The blocks are attributed with fields containing information on:
- Block ID
- Parent 1 Million Mapsheet
- Offshore Area
- Epoch of the boundaries used to cut the data  AMB2014
- Datum
- Origin of the mapsheet in AGD66
- The position of all vertices in the block
- The number of vertices in the block
- The area of the block in acres
- The area of the block in hectares
The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.

Detailed Gravity Survey, SA 2006A10 (P200652), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected 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 Detailed Gravity Survey, SA 2006A10 (P200652) contains a total of 625 point data values acquired at a spacing between 150 and 400 metres. The data is located in SA and were acquired in 2006, under project No. 200652 for None.

Birrindudu - Browns Range Dome, NT, 1997 (P1001), magnetic line data, AWAGS levelled

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.
 These line dataset from the Tanami/Birrindudu, NT, 1997 survey were acquired in 1997 by the NT Government, and consisted of 81828 line-kilometres of data at a line spacing between 200m and 200m, and 60m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Great Artesian Basin - Cadna-owie Hooray Aquifer - Sulphate Concentration

Data used to produce the predicted Sulphate map for the Cadna-owie - Hooray Aquifer in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Cadna-owie - Hooray Aquifer  Sulphate map data
A. Location of hydrochemistry samples (Point data, Shapefile)
B. Predicted Concentration (Filled contours , Shapefile)
C. Predicted Concentration Contours (Contours, Shapefile)
D. Prediction Standard Error (Filled contours , Shapefile)
The predicted values provide a regional based estimate and may be associated with considerable error. It is recommended that the predicted values are read together with the predicted error map, which provides an estimate of the absolute standard error associated with the predicted values at any point within the map.
The predicted standard error map provides an absolute standard error associated with the predicted values at any point within the map. Please note this is not a relative error map and the concentration of a parameter needs to be considered when interpreting the map. Predicted standard error values are low where the concentration is low and there is a high density of samples. Predicted standard errors values can be high where the concentration is high and there is moderate variability between nearby samples or where there is a paucity of data.
Concentrations are Sulphate in mg/L.
Coordinate system is Lambert conformal conic GDA 1994, with central meridian 134 degrees longitude, standard parallels at -18 and -36 degrees latitude.
The Cadna-owie - Hooray Aquifer Sulphate map is one of 14 hydrochemistry maps for the Cadna-owie - Hooray Aquifer and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2014).

Thermal history of the Gosses Bluff impact structure, central Australia, from conodont colour-alteration indices: implications for hydrocarbon prospectivity and erosional history

Gosses Bluff is the remnant of a latest Jurassic asteroid or comet impact structure in the Amadeus Basin, central Australia. Conodonts have been successfully extracted from rocks exposed at the central uplift core of the impact structure, as well as from samples in petroleum exploration wells drilled into the structure. Maximum maturation of the source beds in the Early Ordovician Horn Valley Siltstone is reflected by the conodont colour-alteration index (CAl) value of 4 in Gosses Bluff No.2 well.  A similar maturation level was attained by late Early Ordovician carbonates of the Stokes Siltstone, both in outcrop and drilled at shallow levels in Gosses Bluff No.1 well.  A value of CAl 4 at the present surface indicates that these rocks were uplifted at least 4500m as a result of the impact.  Combined with the CAl values from conodonts recovered from petroleum exploration wells to the northeast (Tyler No.1) and southeast (Palm Valley No.1 and West Waterhouse No. 1), the conodont CAl values derived from Gosses Bluff allow the construction of a palaeodepth trend, similar to the CAI-depth trend of the Appalachians and the Kidson Sub-basin of the Canning Basin. This indicates that about 500 m of rock has been eroded from above the Gosses Bluff and Tyler No. 1 well area, and that about 1700- 2800 m has been eroded from the Palm Valley and Waterhouse Range Anticlines. The CAl 4 value for the Horn Valley Siltstone, the primary rich hydrocarbon source rock in the basin, indicates that the organic matter in this formation in the Missionary Plain had reached a level of maturity equivalent to that for production of dry gas before about 140 Ma.
