Introduction to Controlled-Source Electromagnetic Methods

Anton Ziolkowski is Professor of Petroleum Geoscience at the University of Edinburgh. He co-invented the Multichannel Transient Electromagnetic (MTEM) surveying method for hydrocarbon reservoir detection and co-led the technology spin-out. He is a member of the Institute of Electrical and Electronics Engineers and the American Geophysical Union, an honorary member of the Society of Exploration Geophysicists, a Fellow of the Royal Academy of Engineering, and a Fellow of the Royal Society of Edinburgh. He has received the Conrad Schlumberger and Desiderius Erasmus awards of the European Association of Geoscientists and Engineers. Evert Slob is Professor of Geophysical Electromagnetic Methods at theTechnische Universiteit Delft, The Netherlands, where he teaches undergraduate and graduate classes. He was Editor-in-chief of the journal Geophysics and on the board of directors of the Society of Exploration Geophysicists from 2013–15, of which he remains a member. He is also a member of the European Association of Geoscientists and Engineers, and the American Geophysical Union.
