Electromagnetic Geothermometry explores, presents and explains the new technique of temperature estimation within the Earth’s interior; the Electromagnetic technique will identify zones of geothermal anomalies and thus provides locations for deep drilling. This book includes many case studies from geothermal areas such as Travale (Italy), Soultz-sous-Forêts (France) and Hengill (Iceland), allowing the author and reader to draw conclusions regarding the dominating heat transfer mechanisms, location of its sources and to constrain the locations for drilling of the new boreholes. Covering a topic that so far has very little coverage (due to its newness) Electromagnetic Geothermometry presents ground breaking information on the interpretation of MT signals. And as such, is similar to the work that was done to develop new generations of seismic inversion methods that have since come to dominate the oil industry. Up until now geophysical methods have had difficulty resolving temperature differences which have been critical in the understanding of location and magnitude of geothermal resources Authored by the world’s foremost geothermometry experts who combined have more than 40 years of experience on the subject Presents case studies, allowing the author and reader to draw conclusions regarding the dominating heat transfer mechanisms, location of its sources and to constrain the locations for drilling of the new boreholes Provides important information on the constraints for drilling of new exploration boreholes Describes techniques that will dramatically decrease the costs associated with exploration drilling Includes information to help the reader improve the accuracy of the temperature estimations in the interwell space as well as far beneath boreholes

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

This volume is devoted to investigation of all aspects of heat-mass transfer processes at different scales and from various origins, as well as the formation and evolution of geological structures. These phenomena are linked to geophysical properties of rocks, geothermal resources, geothermics, fluid dynamics, stress-state of the lithosphere, deep geodynamics, plate tectonics, and seismicity, among others. The book consists of two main parts. The first concerns heat-mass transfer associated with natural and technogenic processes in the upper lithosphere. The second deals with geodynamics and seismicity. The collection of over 25 chapter from leading investigators in Russia is thus an important contribution to research on the lithosphere in connection with formation and evolution of geological structures; heat and mass transfer processes in the lithosphere and their connection with deep Earth geodynamics. Collects a range of research methodologies including application of modelling, seismic tomography, geological field works, geological-geophysical methods, and in situ measurements through instrumentation; Explains how a wide range of geological and geophysical phenomena arising in the Earth’s lithosphere can be investigated under the umbrella of a common approach to heat-mass transfer processes; Includes the latest research by more than 60 leading scientists from Russia.

Remote sensing data and methods are increasingly being implemented in assessments of volcanic processes and risk. This happens thanks to their capability to provide a spectrum of observation and measurement opportunities to accurately sense the dynamics, magnitude, frequency, and impacts of volcanic activity. This book includes research papers on the use of satellite, aerial, and ground-based remote sensing to detect thermal features and anomalies, investigate lava and pyroclastic flows, predict the flow path of lahars, measure gas emissions and plumes, and estimate ground deformation. The multi-disciplinary character of the approaches employed for volcano monitoring and the combination of a variety of sensor types, platforms, and methods that come out from the papers testify to the current scientific and technology trends toward multi-data and multi-sensor monitoring solutions. The added value of the papers lies in the demonstration of how remote sensing can improve our knowledge of volcanoes that pose a threat to local communities; back-analysis and critical revision of recent volcanic eruptions and unrest periods; and improvement of modeling and prediction methods. Therefore, the selected case studies also demonstrate the societal impact that this scientific discipline can potentially have on volcanic hazard and risk management.

This proceedings book investigates the possibilities for creating new models of the continental lithosphere structure by integrating methods from geothermodynamics and deep geoelectrics. It particularly focuses on the use of powerful controlled sources of electromagnetic field to study the nature of deep geophysical boundaries. It also presents research related to the transition boundary between the brittle and quasiplastic states of Earth’s crust matter and the position of creep areas in Earth’s crust, as well as geothermal and rheological studies in combination with the deep electromagnetic soundings – a promising direction that allows the tectonophysical reconstruction of natural stresses in the lithosphere. The experimental study results and tectonophysical modeling are discussed in the context of the Fennoscandinavian shield, the Indian Craton, the Himalayas, Eastern Tibet and the Eurasian continent as a whole. The book appeals to researchers interested in solid Earth physics.
