Description / Table of Contents: The Rock Physics Handbook addresses the relationships between geophysical observations and the underlying physical properties of rocks. It distills a vast quantity of background theory and laboratory results into a series of concise chapters that provide practical solutions to problems in geophysical data interpretation. This expanded second edition presents major new chapters on statistical rock physics and velocity-porosity-clay models for clastic sediments. Other new and expanded topics include anisotropic seismic signatures, borehole waves, models for fractured media, poroelastic models, and attenuation models. This new edition also provides an enhanced set of appendices with key empirical results, data tables, and an atlas of reservoir rock properties - extended to include carbonates, clays, gas hydrates, and heavy oils. Supported by a website hosting MATLAB routines for implementing the various rock physics formulas, this book is a vital resource for advanced students and university faculty, as well as petroleum industry geophysicists and engineers. A significantly expanded new edition of this practical guide to rock physics and geophysical interpretation for reservoir geophysicists and engineers.

Description / Table of Contents: "This is a hands-on guide for graduate students and other young researchers wishing to perfect the practical skills that are needed for a successful career in research. By teaching junior scientists to develop effective research habits, the book helps make the experience of graduate study a more efficient, effective and rewarding one. Many graduate students learn these skills "on the job", often by doing them poorly at first, with the result that much valuable time can be lost; this book will help prevent that. The authors have taught a graduate course on the topics covered in this book for many years, and provide a sample curriculum for instructors in graduate schools who wish to teach a similar course. ... The wealth of advice offered in this book is invaluable to students, junior researchers and their mentors in all fields of science, engineering and the humanities."
