Acoustic and Elastic Wave Fields in Geophysics, III by Alex Kaufman – Elastic Wave Propagation in Solids and Boreholes

Introduction

For students, researchers, and professionals delving into the complex world of geophysics, understanding elastic wave behaviour is essential. 'Acoustic and Elastic Wave Fields in Geophysics, III' by Alex Kaufman completes a definitive trilogy that bridges theory and real-world application. This hardcover volume, published by Elsevier Science, focuses on the propagation of elastic waves through diverse media, offering a rigorous yet accessible treatment of plane, spherical, and cylindrical waves. Whether you are studying seismology, subsurface imaging, or borehole acoustics, this book provides the foundational knowledge needed to grasp advanced concepts in solid-earth geophysics.

Book Overview

This third and final volume in the series shifts focus from liquid media, covered in the earlier books, to the more intricate behaviour of elastic waves in solid and mixed media. It systematically explores how waves travel through isotropic and transversely isotropic solids, liquid-solid interfaces, and media with cylindrical inclusions such as boreholes. The text is structured to build from fundamental wave theory to complex models, making it an ideal reference for graduate-level courses and independent study. With clear mathematical derivations and physical interpretations, Alex Kaufman ensures that readers not only learn the formulas but also understand the underlying physics.

Key Highlights

• Comprehensive coverage of plane, spherical, and cylindrical elastic wave propagation in various geological settings.
• Detailed analysis of transversely isotropic solids, a critical topic for understanding anisotropic Earth materials.
• Practical focus on liquid-solid models and borehole environments, directly relevant to exploration geophysics and well logging.
• Rigorous mathematical framework paired with intuitive physical explanations, suitable for both theoreticians and applied scientists.
• Part of an acclaimed trilogy by a renowned geophysicist, ensuring consistency and depth across the series.

Inside the Book

The book is divided into well-structured chapters that guide the reader from basic concepts to advanced applications. Early sections revisit the fundamentals of elasticity and wave equations, establishing a solid ground for later discussions. Middle chapters delve into the reflection and refraction of elastic waves at boundaries, including the challenging cases of anisotropic media. The final chapters are dedicated to wave propagation in cylindrical geometries, such as those encountered in borehole seismics and engineering geophysics. Each chapter includes worked examples and problem sets to reinforce learning.

Key Topics

• Elastic wave equations in isotropic and anisotropic solids.
• Plane wave propagation and its application to layered Earth models.
• Spherical and cylindrical waves generated by point sources and line sources.
• Wave interaction at liquid-solid interfaces, including mode conversion.
• Borehole wavefields and guided waves in cylindrical structures.
• Transversely isotropic media and their seismic response.

Reader Benefits

By studying this volume, readers will gain a deep, intuitive grasp of how elastic waves behave in realistic Earth models. The book bridges the gap between abstract theory and practical geophysical problems, enabling readers to interpret seismic data more effectively. It also serves as a valuable reference for designing numerical simulations and understanding wave-based imaging techniques. The clear, step-by-step derivations make complex topics manageable, saving hours of effort in self-study.
