An interpretation of the crustal temperature at 5km depth, based on the OzTemp bottom hole temperature database and additional confidential company data. A simple two layer model has been used for the extrapolation of the temperature to 5km depth; where the data quality and availability has allowed a slightly more complex three layer model using heatflow and thermal conductivity data was used for the extrapolation.
