Geophysical Electromagnetic Theory and Methods: Volume 43

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 methods-direct current (DC), induced polarization (IP), magnetotelluric(MT), and controlled-source electromagnetic (CSEM) methods-and covers different applications of EM methods in exploration geophysics, includingminerals and HC exploration, environmental study, and crustal study.

Klappentext

In this book the author presents both the foundations and the most recent achievements of electromagnetic (EM) geophysical methods in the framework of a unified systematic exposition. The EM methods comprise one of the three principle technologies in applied geophysics (the other two being seismic methods and potential field methods). The book brings together fundamental theory of EM field and practical aspects of EM exploration for mineral and energy resources. The publication is unique in its breadth and completeness in providing a general picture of the current state-of-the-art in EM geophysical exploration technology.

Zusammenfassung
