Great Artesian Basin - Adori-Springbok Aquifer - Thickness and Extent

The Adori-Springbok Aquifer - Thickness and Extent data set, is one of a set that represents the hydrostratigraphic units of the Great Artesian Basin, which include five major aquifers, four intervening aquitards, and the Cenozoic cover to the GAB.


There are five layers in the Adori-Springbok Aquifer map data.


A: Formation Extent

B: Outcrop extent

C: Isopach Raster

D: Isopach Contours

E: Data Point Locations


The datasets have been derived from the lithostratigraphic intercepts in drillhole data from petroleum exploration wells, water bores, and stratigraphic wells. Seismic correlation and assessment of hydrogeological character based on electrofacies have not been used. The working datasest for this study has been derived primarily from the following databases:


1. PEPS-SA (Petroleum Exploration and Production System - South Australia) (Department of Primary Industries and Regions SA, 2011)

2. WaterConnect Groundwater database (Govt. of SA, 2011)

3. QPED (Queensland Petroleum exploration database) (Geological Survey of Queensland, 2010).

4. GABLOG (Great Artesian Basin Well Log Dataset) (Habermehl, 2001)

5. Additional supplementary information was derived from published reports listed in the following section.


This is a regional interpretation for mapping at approximately 1:1 000 000 to produce a broad scale overview, and examination of small areas by collecting extra data is most likely to produce results that differ from this regional interpretation.

METHOD:

Formation Extent

Extents were based on drillhole data from GABLOG (Habermehl, M. A., 2001), PEPS-SA (Department of Primary Industries and Regions SA, 2011), QPED (Geological Survey of Queensland, 2010) and WaterConnect Groundwater database (Govt. of SA, 2011).

Extent lines were adjusted to envelop all intercepts of the Hydrostratigraphic unit. This produced some varied and irregular shapes, some patchy regions, and required some interpretation to establish the most likely extent boundary.


Outcrop Extent

Outcrop extents came from 'Hydrogeology of the Great Artesian Basin Australia' (Habermehl & Lau, 1997) for the Eromanga and Surat sub-basins. For the Carpentaria Basin, Mesozoic Geology of the Carpentaria and Laura Basins (Geoscience Australia, 2013) was used.


Isopach Raster

Source point thickness values calculated from drillhole intercepts were extrapolated using the ESRI ANUDEM Topo-To-Raster surface modeller. Zero thickness constraints were applied at the known extent of the aquifer/aquitard, except in cases where the formation extends beyond the GAB boundary (for example the Precipice formation on the eastern side of the GAB, where the formation is quite thick and is exposed as a cliff). In these cases, constraints were not applied and the software was allowed to model a thickness right up to the GAB boundary. Resulting grids were modified using the ESRI Grid Calculator to set the minimum thickness to 0, and clipped to the aquifer/aquitard extent.


Isopach Contour

Isopach contours were calculated from the Adori-Springbok aquifer thickness grid using the ESRI Contour Tool. These were calculated at 50m intervals. In most cases the zero contour lines generated by the tool were replaced by the extent of the aquifer due to the erratic nature of the generated lines. In cases where the aquifer/aquitard is thick at the extent, the zero isoline is outside the extent and is not mapped in that area. Isopachs were clipped to the aquifer/aquitard extent.


Data Point Locations

Data Point Locations have been derived from the bore hole data collected for this project. Only the location has been included.


SOFTWARE:

All modifications/edits and geoprocessing were performed using ESRI ArcGIS 10 software.
