P026 Pipes Detection Using VLF Method Abstract 1 EM methods are one of most important methods in conductors prospecting. In this research the application of VLF method has been studied in order to find metallic pipes. VLF data was acquired by WADI instrument (ABEM Co.) and then raw data was interpreted using a new version of Karoos & Hjelt (1983) filter which was proposed by the author (Amini 2004).
