Multifrequency Electromagnetic Data Interpretation for Subsurface Characterization

Multifrequency Electromagnetic Data Interpretation for Subsurface Characterization focuses on the development and application of electromagnetic measurement methodologies and their interpretation techniques for subsurface characterization. The book guides readers on how to characterize and understand materials using electromagnetic measurements, including dielectric permittivity, resistivity and conductivity measurements. This reference will be useful for subsurface engineers, petrophysicists, subsurface data analysts, geophysicists, hydrogeologists, and geoscientists who want to know how to develop tools and techniques of electromagnetic measurements and interpretation for subsurface characterization.

• Includes case studies to add additional color to the presented content
• Provides codes for the mechanistic modeling of multi-frequency conductivity and relative permittivity of porous geomaterials
• Presents detailed descriptions of multifrequency electromagnetic data interpretation models and inversion algorithm

Engineers, Geoscientists, and Geophysicists involved in subsurface engineering and characterization for fossil fuel extraction, geothermal energy production, carbon sequestration, groundwater hydrology, and mineral resource extraction projects. Primary audience also includes engineers and scientists involved in non-destructive testing and material characterization using electromagnetic methods
