TEM for well siting at Hilton Addis
conference contributionposted on 12.02.2018, 15:11 by Seleshi Mekonen
A successful thermal water well drilling site was selected using Professional Transient Electro-Magnetic Sounding survey at Hilton Addis. The survey is conducted using GEONICS PROTEM 47 and 57 transmitters and Digital receiver. A total of three TEM sounding surveys were carried out based on priory information found from gravity and magnetic survey data. An anomalous low apparent resistivity response in the order of magnitude of 10 WW-m is exhibited below a depth of about 340 meters and interpreted as thermal ground water bearing horizon. Based on which a potential deep water well is drilled to a depth of 420 meters and is in conformity to the TEM survey results.
