Theory of Electromagnetic Well Logging

Theory of Electromagnetic Well Logging provides a much-needed and complete analytical method for electromagnetic well logging technology. The book presents the physics and mathematics behind the effective measurement of rock properties using boreholes, allowing geophysicists, petrophysisists, geologists and engineers to interpret them in a more rigorous way.

Starting with the fundamental concepts, the book then moves on to the more classic subject of wireline induction logging, before exploring the subject of LWD logging, concluding with new thoughts on electromagnetic telemetry. Theory of Electromagnetic Well Logging is the only book offering an in-depth discussion of the analytical and numerical techniques needed for expert use of those new logging techniques.

Features in-depth analysis of the analytical and numerical techniques needed for expert use of logging techniquesIncludes software codes, providing a handy tool for understanding logging tool physics and design of new logging toolsProvides a detailed glossary of all key terms within the introductory chapter
