Book Description
Electromagnetic Sounding of the Earth's Interior 2nd edition provides a comprehensive up-to-date collection of contributions, covering methodological, computational and practical aspects of Electromagnetic sounding of the Earth by different techniques at global, regional and local scales. Moreover, it contains new developments such as the concept of self-consistent tasks of geophysics and , 3-D interpretation of the TEM sounding which, so far, have not all been covered by one book. Electromagnetic Sounding of the Earth's Interior 2nd edition consists of three parts: I- EM sounding methods, II- Forward modelling and inversion techniques, and III - Data processing, analysis, modelling and interpretation. The new edition includes brand new chapters on Pulse and frequency electromagnetic sounding for hydrocarbon offshore exploration. Additionally all other chapters have been extensively updated to include new developments. - Presents recently developed methodological findings of the earth's study, including seismoelectrical and renewed magnetovariational approaches - Provides methodological guidelines for Electromagnetic data interpretation in various geological environments - Contains a balanced set of lectures covering all aspects of Electromagnetic sounding at global, regional and local levels along with case studies, highlighting the practical importance of electromagnetic data - Updates current findings in the field, in particular MT, magnetovariational and seismo-electrical methods and the practice of 3D interpretations

The behavior of the magnetic and electric fields from a vertical magnetic dipole source at the surface of the earth (after Wait [1951,1955]). earth, the experimental curve so plotted should have the same shape as a portion of the ap propriate theoretical curve, but with the ordinates and abscissas shifted by an amount dependent on the resistivity. The conductivity can be determined from the amount of shift between the field data and the theoretical curve. A detailed description of the curve matching procedure is found in a text by Keller and Frischknecht (1966). The curve matching procedure, though used, has several disadvantages. Measurements must be made over a diagnostic portion of the theoretical curve, one in which there is some curvature, so that the amount of shift required to make a match can be determined uniquely. This means that the approximate conductivity of the earth must be known when measurements are made. Secondly, determination of a single value of conductivity requires measurements made over a wide range of frequencies. This would appear to be wasteful of data, inasmuch as the equations indicate that a single measurement at a single frequency should be enough to de termine conductivity.

Book Description
Direct Current Geoelectric Sounding: Principles and Interpretation provides a comprehensive review of the Schlumberger method of geoelectric sounding, as well as current methods of interpretation. It explores the theoretical foundations of geoelectric sounding, the relative advantages and limitations of the two symmetrical arrangements for vertical electrical sounding, the techniques of interpretation for Wenner sounding curves, and dipole sounding. This volume is based on educational materials used in the study of geoelectric sounding. It begins with an overview of the theory of current flow in a horizontally stratified Earth, followed by a discussion of how the resistivity of the ground is measured. The book explains the current flow in a homogeneous anisotropic and horizontally stratified Earth, the principle of equivalence, and vertical electrical sounding. Moreover, it presents the basic principles and procedures for the construction of theoretical master curves. Asymptotic values of Schlumberger curves, the principle of reduction of two layers and of a three-layer Earth, and Tagg's method of interpretation are also discussed. The book explains the interpretation by curve-matching, characteristics of dipole electric sounding, and geological applications of electrical resistivity sounding. Engineering problems and application examples with self-explanatory diagrams are provided at the end of the chapters. This book will benefit undergraduate and postgraduate students who want to broaden their understanding of exploration geophysics, as well as professional exploration geologists and geophysicists, civil engineers, agricultural scientists, and researchers.
