Book Description
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.

Book Description
Mathematically rigorous, computationally fast, and easy to use, this new approach to electromagnetic well logging gives the reservoir engineer a new dimension to MWD/LWD interpretation and tool design Almost all publications on borehole electromagnetics deal with idealizations that are not acceptable physically. On the other hand, “exact models” are only available through detailed finite element or finite difference analysis, and more often than not, simply describe case studies for special applications. In either case, the models are not available for general use and the value of the publications is questionable. This new approach provides a rigorous, fully three-dimensional solution to the general problem, developed over almost two decades by a researcher familiar with practical applications and mathematical modeling. Completely validated against exact solutions and physics-based checks through over a hundred documented examples, the self-contained model (with special built-in matrix solvers and iteration algorithms) with a “plain English graphical user interface” has been optimized to run extremely fast – seconds per run as opposed to minutes and hours – and then automatically presents all electric and magnetic field results through integrated three-dimensional color graphics. In addition to state-of-the-art algorithms, basic "utility programs" are also developed, such as simple dipole methods, Biot-Savart large diameter models, nonlinear phase and amplitude interpolation algorithms, and so on. Incredibly useful to oilfield practitioners, this volume is a must-have for serious professionals in the field, and all the algorithms have undergone a laborious validation process with real use in the field.

Book Description
A description is given of the Raytheon Downhole Information System (RDIS), a real time electromagnetic borehole measurements while drilling system, applicable to oil, gas, and geothermal drilling. It communicates in both directions through the earth in a single hop at a downlink data rate of 3 bps and uplink rates dependent on depth--typically 6 bits/second at 10,000 ft and 2 bits/second at 15,000 ft; electromagnetic signal transmission time of approximately .1 second. Downhole hardware for communications, sensors, and power are packaged in three 30 ft subs. Downhole hardware can be developed to permit operation in a 275°C geothermal environment. A cost analysis is included that predicts RDIS service could be economically priced at approximately $1000/day. Commercial availability depends primarily on proof of capability by demonstration in a working drilling well. The most significant portions of needed hardware are available. A description of a geothermal drilling telemetry system is included in Appendix A.

Book Description
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.

Book Description
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
