Geophysical Electromagnetic Theory and MethodsBy
- Michael Zhdanov, Department of Geology and Geophysics, University of Utah, Salt Lake City, USA
In this book the author presents the state-of-the-art electromagnetic (EM)theories and methods employed in EM geophysical exploration.The book brings together the fundamental theory of EM fields and the practicalaspects of EM exploration for mineral and energy resources.This text is unique in its breadth and completeness in providing anoverview of EM geophysical exploration technology. The book is divided into four parts covering the foundations of EMfield theory and its applications, and emerging geophysical methods.Part I is an introduction to the field theory required for baselineunderstanding. Part II is an overview of all the basic elements ofgeophysical EM theory, from Maxwell's fundamental equations to modernmethods of modeling the EM field in complex 3-D geoelectrical formations. Part III deals with the regularized solution of ill-posedinverse electromagnetic problems, the multidimensional migration and imaging ofelectromagnetic data, and general interpretation techniques. Part IV describes major geophysical electromagnetic methodsdirect current (DC), induced polarization (IP), magnetotelluric(MT), and controlled-source electromagnetic (CSEM) methodsand covers different applications of EM methods in exploration geophysics, includingminerals and HC exploration, environmental study, and crustal study.
