This book explains the theory, numerical modeling, and applications of a borehole electromagnetic telemetry system used for wireless communication between the downhole tool and the surface control center during oilfield drilling. The authors begin by introducing borehole electromagnetic telemetry and explaining each part of the system with schematics and illustrations. They describe the working principle and compare it with other borehole wireless communication methods, such as mud pulse telemetry. They then address 2D and 3D electromagnetic telemetry modelling, listing previous 2D and 3D modeling methods and detailing the advantages and limitations, before discussing their recent work on a novel layered finite element method for 2D electromagnetic telemetry modelling, and on 3D electromagnetic modelling based on integral equation, thin wire kernel, and layered medium Green’s functions. Lastly, the authors show applications of electromagnetic telemetry, including single well borehole wireless communication and cross well communication in pad drilling. This includes photos, figures, and field data from real oilfield jobs. This book is a useful reference for drilling engineers, well logging tool research and development scientists and researchers, as well as for students in the areas of petroleum engineering and electrical engineering.

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 techniques - Includes software codes, providing a handy tool for understanding logging tool physics and design of new logging tools - Provides a detailed glossary of all key terms within the introductory chapter

This report summarizes the development of a through-the-earth electromagnetic communication system which was designed to demonstrate that a physical property could be measured deep in the earth and the data received at the surface by wireless telemetry. This system was configured to be placed in a borehole and sealed in place thus preventing the establishment of a pathway between a deep geologic nuclear waste repository and the biosphere. This report contains a detailed description of the downhole and wellhead telemetry electronics, the downhole sensor electronics, integrated system operation, test results, conclusions, and recommendations.
