Title: New heat flow interpretations for the Australian continent

Description

Abstract:

Current understanding of Australia's geothermal resources is based on limited data such as temperature measurements taken in petroleum and mineral boreholes across the country. Heat flow studies are rarer, with existing publicly available compilations containing less than 150 heat flow data-points for Australia. Both temperature and heat flow data are unevenly distributed and, where no data exist, the available information has been interpolated over large areas to generate national-scale maps.

Geoscience Australia has acquired the field and laboratory equipment required to measure heat flow. It began thermal logging of boreholes across Australia in late 2008 and has since collected 155 temperature logs. In late 2009, the thermal conductivity meter became operational, allowing the project to begin thermal conductivity measurements of samples collected from logged boreholes. To help clear some of the backlog of samples collected during 2008-09, the measurement of some of these samples has been contracted out.

This record details the first set of new heat flow interpretations to be released by Geoscience Australia. The remaining temperature logs will be interpreted for heat flow and released, as thermal conductivity data for these holes become available.
