Logistics report for down-hole conductivity logging in the Pine Creek AEM Survey area, Northern Territory, 2008

Induction conductivity data, commonly referred to as conductivity logs, were acquired from twenty four boreholes during two field campaigns in April and October 2008 in support of the Pine Creek airborne electromagnetic (AEM) survey, described in Costelloe (2010). The Pine Creek AEM survey comprises three areas: Kombolgie to the east of Kakadu National Park; Woolner Granite near Darwin; and, Rum Jungle to the west of Kakadu National Park. Data in the Woolner Granite and Rum Jungle survey areas were acquired using the TEMPESTTM fixed wing AEM system. The acquisition and processing were carried out by Fugro Airborne Surveys Pty. Ltd. (FAS), under contract to GA. In the Kombolgie survey area, the data were acquired by Geotech Airborne Pty. Ltd. (Geotech) using the VTEM helicopter AEM system. The geophysical investigations were designed to deliver reliable, pre-competitive AEM data and scientific analysis of the energy resource potential of the Pine Creek region of Northern Territory. The Pine Creek AEM survey covers a total area of 73 700 km2 in the Pine Creek region of the Northern Territory.
