Stéphane Sainson obtained his Ph.D. degree in geophysics in 1984 (Applied Geophysics Laboratory of the Ecole Normale Supérieure de Paris). After working several years as a diver and as a prospector, Dr. Sainson subsequently held the positions of research engineer in wireline logging, project leader in borehole seismic (Schlumberger) and finally R & D manager for special offshore operations on pipelines (Challenger of Vinci group). S. Sainson exercises his independent consulting engineering profession since 1997.
“The book provides a good overview of marine EM methods and their application for those starting out in the subject or wanting to learn more about the principles and practice. For specialists or those who want to dig further into the ideas that are discussed, there is an extensive bibliography, which is in itself extremely useful.” (Lucy MacGregor, The Leading Edge, October, 2017)
