Abstract

A survey was carried out over the Tallyabra anticline in the Eromanga Basin Queensland, using both controlled source and passive magnetotelluric techniques to investigate the structure in the top 2 km. The results from the controlled source system were very encouraging and, using the resistivity log from the well Kenmore 7 as a control, the top of the oil bearing Hutton Sandstone was resolved at a depth of about 1400 m. The magnetotelluric results were consistent with those from the controlled source, but the data accuracy was so much lower that in these circumstances they added little information.
