Logistics report for down-hole conductivity logging in the Paterson AEM Survey area, Western Australia, September 2008

Brief description

Induction conductivity data, commonly referred to as conductivity logs, were acquired from nineteen boreholes during September 2008 in support of the Paterson airborne electromagnetic (AEM) survey, described in Roach (2010). The geophysical investigations were designed to deliver reliable, pre-competitive AEM data and scientific analysis of the energy resource potential of the Paterson region of Western Australia. The Paterson AEM survey was the first regional AEM survey conducted in the Onshore Energy Security Program (OESP) at Geoscience Australia (GA). The survey was flown by Fugro Airborne Surveys Pty. Ltd. (FAS), for Geoscience Australia, as a combined TEMPESTTM time-domain electromagnetic (TEM) and magnetic survey between the 10th of September 2007 and the 28th of October 2008. The Paterson AEM survey covers a total area of 49 000 km2 in the Paterson region of Western Australia. Induction conductivity log data were acquired from the boreholes across a number of widespread, different geological units within the Paterson AEM survey area. The conductivity logs were used to assist in generating reference models for geophysical inversions of the AEM data, as well as for assessing the results of the inversions as an independent dataset.
