The Department for Energy and Mining makes a comprehensive range of data for industry use.

Data includes:

  • workstation datasets (by basin);
  • depth, time and isopach maps;
  • other reference maps;
  • field data, and
  • processed seismic data.

Available basic seismic data is considered to be all data required for the reprocessing of existing seismic lines or processed data that could facilitate the reinterpretation of any prospect or area. Key datasets have been catalogued and entered into PEPS-SA. Some key datasets with a GIS component are available for viewing in South Australia Resources Information Geoserver (SARIG)

New checkshot database for onshore petroleum provinces in South Australia

The Geoscience and Exploration branch of the Energy Resources Division is in the process of compiling a checkshot database for the whole of onshore South Australia. Phase One has now been completed, covering all of the wells in the Otway Basin. Additionally, a software tool has been developed in-house to allow viewing, analysis and validation of these data. Checkshot surveys from the other petroleum provinces in South Australia will be added incrementally as the next stages of the project are completed.

The database is available as a free download:

Onshore seismic data

In South Australia onshore seismic exploration activities are controlled by the South Australian Petroleum & Geothermal Energy Act 2000. Under this Act, all 'Basic data', including field data tapes and supporting documentation are made open file and available for third party use 2 years from the date of completion of the survey.

As a service to the petroleum exploration industry, field data tapes for all recently (1974+) digitally recorded onshore seismic surveys (2D and 3D) have been transcribed to a de-multiplexed SEG-Y format and are now for purchase.

All associated field support data necessary for reprocessing the field data are also available upon request.

Offshore seismic data

Since 2012 all offshore exploration activities are managed by two Commonwealth agencies, NOPSEMA and NOPTA, who administer the Offshore Petroleum & Greenhouse Gas Storage Act 2006 (OPGGSA). All data submitted under this Act are administered by the Federal Government agency, Geoscience Australia (GA).

All requests for offshore data should be made through the Geoscience Australia Repository.

Seismic_shotpoint_databaseThis is a comprehensive digital data set of shotpoint locations and associated attribute data from over 880 seismic surveys carried out as part of petroleum exploration in South Australia and adjacent waters to latitude 40°S since 1955.

The index to these data and summary information are also available in PEPS-SA.

Line location data is available for purchase in various formats (ESRI shapefile, ASCII) and can be supplied on a variety of media types.

More information of this application through SARIG.

Ancillary Data

The entire collection of seismic support documents for all post 1975 onshore seismic lines has been collated, indexed and scanned and is now available as digital, multi-page tiff image files on an individual line basis.

Originally contained in some 750 archive boxes the data set is now stored on hard disk. This data when combined with the digital data submissions for current data (post 2000) makes for an extremely fast and efficient data provision service for reprocessing projects.

The key data is available as multi-page tiff image files and includes images of Observers Logs, Elevation and Coordinate Listings, Uphole Plots, Intersection Diagrams and Chainage Notes.

Uphole data

Uphole Data recorded in South Australia has been successfully captured and is available through PEPS_SA.

In all there are some 48000 upholes from 7000 seismic lines recorded for 240 surveys during the period 1975–2012. These upholes are located in all main prospective areas of the state but are concentrated primarily in the: Cooper-Eromanga Basin, Otway Basin, Officer Basin and Pedirka Basin.

Attribute data captured for each uphole includes Seismic Line and Shot Point reference, Date, Elevation and Coordinates in both original form and in GDA94 datum.

Time versus Depth pairs have been entered to enable screen validation of the resultant time vs depth curves.

ASCII files of these data are available upon request.

All 2D and 3D seismic surveys recorded in South Australia are indexed with a 'survey code plus key attribute data. The survey code incorporates the year of recording, the geological province plus the survey sequence number within that province for that particular year.  When referencing these surveys you should always incorporate the survey code.

Attribute data is available from the “Surveys and Lines” module in PEPS-SA.

Most of these surveys were recorded by petroleum exploration companies holding exploration permits. There are however references to surveys which were either site surveys, engineering, mineral or that of an academic nature. Reference is also made to interstate surveys which either cross or come near to the SA border.

More information of this dataset application through SARIG.


The Department for Energy and Mining has an extensive collection of processed archive 2D and 3D data in a SEG Y format. This collection is considered complete for all company exploration activities post 1975. All available attribute data has been captured into PEPS-SA as a lot of original data lacks the standard information necessary to facilitate correct data loading into workstation platforms.

Due to the complexity of versions created during reprocessing, and general poor data standards of data presentation, DEM has prepared a series of "workstation ready" SEG Y datasets for 2D seismic data. For more information see the section on Workstation Datasets.

A limited number of files and volumes have been selected for both 2D and 3D seismic surveys and these are now downloadable for free through SARIG. These files have been selected on the basis of longest, most complete, best version and most recent data.

Archive processed data in a seg-y format are available for most seismic lines recorded post 1975. Some earlier "analogue data" lines are available but this is the result of reprocessing and Analogue to Digital transcription of early analogue data.

Data is generally made available in a form "as supplied" to DEM and all available attribute data has been captured in PEPS-SA.

Due to the complexity of versions, reprocessing and poor standards of early data, DEM has prepared a series of Workstation Ready seg-y data sets based on a province basis. These data sets have been tied, adjusted and key attribute data added to assist the explorer with the complexities of data loading. For more information on these data sets see Workstation Datasets.

Archive processed seg-y data for all open file 3D seismic surveys are available for purchase. Onshore 3D surveys have been recorded in South Australia since 1981 and over 100 surveys have now been recorded. The majority of these have been in the Cooper-Eromanga basin area.

Many of these surveys have an extensive list of processed data volumes and requests for these volumes are generally only provided on portable USB drives/sticks due to large volumes. As a service to industry a single version of processed data for each open file survey is available for download through SARIG.

As at November 2016 processed data from over 70 of these open file surveys in the Cooper Basin area have been merged (stitched) together to form a series of geo-referenced time slices through the sedimentary section. These time slices have been prepared at 100msec intervals from 1 second to 2.9 seconds and are available for download through SARIG.

The entire collection of over 39,500 hardcopy seismic sections held by DEM are fully indexed and catalogued in the PEPS-SA database.

Key attributes which have been captured include:

*  Line name
*  Shot point range
*  Display scales
*  Form of processing
*  Date of processing
*  Processing contractor
*  Length of display material

Access to this catalogue is available through PEPS-SA which now facilitates a fast turn around on data orders and customer queries. Digital scanning of these hard copy section commenced in October 1999 under the TEISA initiative and was completed in July 2002. Data is now available as .TIF images upon request.

Since approximately 1996 displays of processed seismic data have been submitted in a CGM+ format by exploration companies. This includes 2D subsets of 3D seismic surveys. These files have been converted to .TIF files to facilitate easy viewing on PCs. The open file data is available for purchase at A$5 per file.


The Department for Energy and Mining has prepared a range of seismic mapping products on a regional basis for major South Australian basins available for viewing and/or purchase.

Products are available for the following prospective petroleum basins:

Cooper and Eromanga Basin
*  Otway Basin
*  Officer Basin

Input data for these projects has been derived from a range of sources, including, Well tops, water bore information, processed seismic data and open file company interpretations.

Petrosys mapping and interpretation software were utilized in all gridding, contouring and data presentation. In general output products comprise Time, Depth and Isopach data for key seismic marker horizons.

Georeferenced tif images of many of these horizons are promoted for viewing through SARIG to highlight extent of coverage and detail. These can be downloaded as georeferenced tif images.

Grids, contours, polygon and fault files and other format files are available on request.
