Computational Geo-Electromagnetics : Methods, Models, and Forecasts

Computational Geo-Electromagnetics: Methods, Models, and Forecasts, Volume Five in the Computational Geophysics series, is devoted to techniques for building of geoelectrical models from electromagnetic data, featuring Bayesian statistical analysis and neural network algorithms. These models are applied to studying the geoelectrical structure of famous volcanoes (i.e., Vesuvio, Kilauea, Elbrus, Komagatake, Hengill) and geothermal zones (i.e., Travale, Italy; Soultz-sous-Forets, Elsace). Methodological recommendations are given on electromagnetic sounding of faults as well as geothermal and hydrocarbon reservoirs. Techniques for forecasting of petrophysical properties from the electrical resistivity as proxy parameter are also considered.

Computational Geo-Electromagnetics: Methods, Models, and Forecasts offers techniques and algorithms for building geoelectrical models under conditions of rare or irregularly distributed EM data and/or lack of prior geological and geophysical information. This volume also includes methodological guidelines on interpretation of electromagnetic sounding data depending on goals of the study. Finally, it details computational algorithms for using electrical resistivity for properties beyond boreholes.

• Provides algorithms for inversion of incomplete, rare or irregularly distributed EM data
• Features methodological issues of building geoelectrical models
• Offers techniques for retrieving petrophysical properties from EM sounding data and well logs

With over 30 years’ geophysics experience, Dr. Spichak’s main research interests include joint interpretation of electromagnetic and other geophysical data, indirect estimation of the Earth’s physical properties from the ground electromagnetic data, and computational electromagnetics. Spichak has authored and edited 8 books with Elsevier, including Electromagnetic Sounding of the Earth's Interior (2015). He is the winner of the Gamburtsev award for the monograph “Magnetotelluric fields in three-dimensional models of geoelectrics” (1999) and the Schmidt medal for outstanding achievements in Geophysics (2010).
