Foundations of geophysical electromagnetic. Theory and methods / Основы электромагнитной геофизики. Теория и методы

Geophysical methods are based on studying the propagation of the different physical fields within the earth’s interior. One of the most widely used fields in geophysics is the electromagnetic field generated by natural or artificial (controlled) sources. Electromagnetic methods comprise one of the three principle technologies in applied geophysics (the other two being seismic methods and potential field methods). In this book the author presents both the foundations and the most recent achievements of electromagnetic geophysical methods in the framework of a unified systematic exposition.The book is divided into four parts covering the foundations of field theory and its applications to applied electromagnetic geophysics, including new emerging methods of marine electromagnetic exploration. The first part is an introduction to field theory required for understanding the basics of geophysical electromagnetic theory. The second part contains all the principal elements of geophysical electromagnetic theory from a description of the fundamental Maxwell’s equations to modern methods of modeling electromagnetic fields in complex 3-D geoelectrical formations. The following part, Part 3, deals with important aspects of the electromagnetic methods, which include principles of the regularized solution of ill-posed inverse electromagnetic problems, one-dimensional and multidimensional imaging and inversion of electromagnetic data, and general interpretation techniques. The final part, Part 4, covers specific geophysical electromagnetic methods. <...>
