Principles of Induction Logging by Avital Kaufman,Yu.A. Dashevsky Pdf

The monograph introduces the reader to the world of inductive well logging - an established method for surveying the electrical conductivity of rocks surrounding a borehole. The emphasis is on developing a theory of inductive logging and on understanding logging tools basic physics, since this theory and understanding furnish valuable insights for inventing practical induction logging techniques. The first chapter of the book presents the basic laws of electromagnetism from a point of view that will facilitate the application of the theory to problems in electromagnetic logging. Many topics that play an important role in the design and interpretation of tools readings are covered. The vertical resolution and radial depth of investigation of different induction tools is systematically considered. Special attention is paid to principles of induction logging with transversal induction coils, to transient method of induction logging in media with cylindrical and horizontal interfaces and to the influence of anisotropy on the electromagnetic field measured in a conducting medium. Multi-coil differential induction probes and induction logging based on measuring the inphase component of the secondary field or the quadrature component difference are also described in detail. The last chapter is devoted to mathematical modeling of the response of induction logging tools in 3D geometries. The theory of inductive logging presented in this volume can be applied to logging after drilling as well as logging while drilling.

Electromagnetic Well Logging by Wilson C. Chin Pdf

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.

Borehole Electromagnetic Telemetry System by Jiefu Chen,Shubin Zeng,Yueqin Huang Pdf

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.

Geophysical Well Logging by Jay Tittman Pdf

Geophysical Well Logging is a three-chapter text that discusses the physics of well logging measurements. This book describes the techniques universally used in formation evaluation, including electrical, nuclear, and sonic techniques. Chapter 1 deals with the special features of logging measurements, tool design, and the relation between logging and coring. This chapter also examines the hostile downhole environment as basic sonde configurations and combination tools. Chapter 2 discusses elementary interpretation principles, the role of logging in formation evaluation, and the uninitiated to the motivation for the wide variety of measurements found in practice. Chapter 3 investigates the physics behind electrode and induction methods for measuring electrical resistivity, as well as the concepts of geometric factor, skin effect, focused measurements, and pseudo-geometric factor. It also considers significant topics on neutron transport and moderation and their application to neutron sonde design and logging measurements; gamma-ray transport and its application to density and photoelectric-absorption logging; methods for the measurement of gamma-ray spectra; and scintillation and germanium spectrometers. This chapter further explores the body and borehole waves of the sonic methods; waves in porous media; conventional interval-transit-time techniques; and full-waveform analysis methods. Physicists, chemists, and engineers who are interested in geophysical field-measurement methods will greatly benefit from this book.

Applied Geophysics by W. M. Telford,L. P. Geldart,R. E. Sheriff Pdf

This is the completely revised and updated version of the popular and highly regarded textbook, Applied Geophysics. It describes the physical methods involved in exploration for hydrocarbons and minerals, which include gravity, magnetic, seismic, electrical, electromagnetic, radioactivity, and well-logging methods. All aspects of these methods are described, including basic theory, field equipment, techniques of data acquisition, data processing and interpretation, with the objective of locating commercial deposits of minerals, oil, and gas and determining their extent. In the fourteen years or so since the first edition of Applied Geophysics, many changes have taken place in this field, mainly as the result of new techniques, better instrumentation, and increased use of computers in the field and in the interpretation of data. The authors describe these changes in considerable detail, including improved methods of solving the inverse problem, specialized seismic methods, magnetotellurics as a practical exploration method, time-domain electromagnetic methods, increased use of gamma-ray spectrometers, and improved well-logging methods and interpretation.

Well Logging by Yury I. Gorbachev Pdf

The key well logging methods of prospecting exploration, and production of oil, gas ores, and coals are all considered in this volume. The trends in the Soviet Union's development of well logging are similar to those elsewhere, the main difference is that due to the difficulties of bringing ideas into commercial practice, Soviet scientists concentrate on the solutions to theoretical problems. This book presents some of these Russian solutions.
