Hydrocarbon shows data are part of Geoscience Australia’s Reservoir, Facies and Shows (RESFACS) database, which contains depth-based information regarding hydrocarbon shows identified or interpreted during the drilling and evaluation of offshore and onshore petroleum wells. A hydrocarbon show is considered to be any indication of oil or gas observed during the drilling or evaluation of a petroleum well. Shows include data collected from well site observations, well logging, petrophysical analysis and well testing and/or sampling. A show evaluation is the complete analysis of a hydrocarbon-bearing formation with respect to lithology, depth and thickness, type and show value which indicates the potential productivity of the formation. Data entered into the shows table are most commonly sourced from both the Basic and Interpretive volumes of the Well Completion Reports (WCR) provided by the petroleum well operator under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) 2006 and previous Petroleum (submerged Lands) Act (PSLA) 1967. Data is also sourced from hydrocarbon shows evaluations conducted by Geoscience Australia and its predecessor organisations, the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR), and from state and territory geological organisations. Other open file data from company announcements and reports, scientific publications and university theses are also captured. The database structure has evolved over time and will keep changing as different types of petroleum data become available and the delivery platform changes. Data was initially delivered through the Petroleum Wells web page, http://dbforms.ga.gov.au/www/npm.well.search, which is in the process of being decommissioned. The hydrocarbon shows data will be available for viewing and download via the Geoscience Australia Portal Core, https://portal.ga.gov.au/.

This OGC conformant web service delivers data from Geoscience Australia's Reservoir, Facies and Hydrocarbon Shows (RESFACS) Database. RESFACS is an interpretative reservoir/facies database containing depth-based information regarding permeability, porosity, shows, depositional environment and biostratigraphy of petroleum wells.

A depositional environment is defined as a site where sediments (e.g. detrital, chemical) accumulated, governed by physical, biological, and chemical processes related to modern environments such as fluvial, deltaic or marine. Once the sediments are lithified during burial processes, sedimentary rocks are assigned to ancient environments, referred to as palaeodepositional environments. Characteristics of sedimentary rocks often used to interpret depositional environments include lithology, sedimentary structures and textures, and any preserved fossils – all of which provide important information regarding the geologic evolution of sedimentary basins. Depositional environment data form part of Geoscience Australia’s Reservoir, Facies and Shows (RESFACS) database. It contains depth-based information regarding palaeogeographic settings interpreted from lithofacies analysis. Interpretations are based on lithological and sedimentary structure evaluations, well log analysis, and palynological and (micro)palaeontological analyses of sediments that were intersected by offshore petroleum wells. Data entered into the depositional environment table is primarily sourced from both the Basic and Interpretive volumes of Well Completion Reports (WCR) provided by the petroleum industry under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) 2006 and previous Petroleum (submerged Lands) Act (PSLA) 1967. Data is also sourced from litho- and bio-facies evaluations and palaeontological studies by Geoscience Australia and its predecessor organisations, the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR), as well as from state and territory geological organisations, scientific publications, university theses and books. The database structure has evolved over time and will keep changing as different types of relevant data become available and the delivery platform changes. Data hosted within Geoscience Australia’s Oracle petroleum wells database was initially delivered through the Petroleum Wells web page, http://dbforms.ga.gov.au/www/npm.well.search, which is due to be decommissioned in the future. The depositional environment data will now be available to view and download through the Geoscience Australia Portal Core, https://portal.ga.gov.au/.

This OGC conformant web service delivers data from Geoscience Australia's Reservoir, Facies and Hydrocarbon Shows (RESFACS) Database. RESFACS is an interpretative reservoir/facies database containing depth-based information regarding permeability, porosity, shows, depositional environment and biostratigraphy of petroleum wells.

Porosity and permeability data form part of Geoscience Australia’s Reservoir, Facies and Shows (RESFACS) database, which contains depth-based information regarding porosity and permeability measured or interpreted from core, sidewall core and well-log analysis of rocks intersected by offshore petroleum wells. Porosity and permeability are rock properties related to the number, size, and connectivity of openings in the rock. More specifically, porosity of a rock is a measure of its ability to hold a fluid within pore-spaces and the permeability is a measure of the ease of flow of a fluid through a porous solid. Data entered into the porosity and permeability tables are primarily sourced from the Basic and Interpretive volumes of Well Completion Reports (WCR) provided by the petroleum industry to the Commonwealth under the Offshore Petroleum and Greenhouse Gas Storage Act (OPGGSA) 2006 and the previous Petroleum (submerged Lands) Act (PSLA) 1967. Data is also sourced from sedimentologic evaluations and petrophysical studies by Geoscience Australia and its predecessor organisations, the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR), as well as from state and territory geological organisations, and scientific publications. The database structure has evolved over time and will keep changing as different types of relevant data become available and the delivery platform changes. Data hosted within Geoscience Australia’s Oracle petroleum wells database was initially delivered through the Petroleum Wells web page, http://dbforms.ga.gov.au/www/npm.well.search, which is in the process of being decommissioned .
