Elementary, conceptual, and easy to read, this book describes the methods and techniques used to estimate rock properties from seismic data, based on a sound understanding of the elastic properties of materials and rocks and how the amplitudes of seismic reflections change with those properties.

Written for practicing geophysicists, this is a comprehensive guide to understanding and analysing seismic data. The culmination of land seismic data acquisition and processing projects conducted by the author over the last two decades, the book contains nearly 800 figures from worldwide case studies - conducted in both 2D and 3D.

Provides a foundation for understanding the fascinating field of seismic processing. Written for the non-expert, this two-volume introductory text reveals the limitations and potential pitfalls of seismic data, prepares both seismic interpreters and acquisition specialists for working with seismic processing geophysicists, and much more.

Written for students as well as professionals who work with and support geophysicists, this book presents a simple and informal discussion of fundamental concepts which underlie the quantitative part of geophysical analysis and interpretation.

Addresses the properties of seismic waves of fractured media by describing, modelling, and analysing the various seismic wave responses from discrete fractured media. The book proposes a methodology for the direct detection of fractured reservoirs based on these analyses.

Providing an overview of how 3D seismic attributes provide a framework for data integration over the life of the oil and gas field, key concepts are illustrated by example, showing modern workflows based on interactive interpretation and display as well as those aided by machine learning.

Describes the theory and practice of inverting seismic data for subsurface rock properties of the earth. The primary application is for inverting reflection and transmission data from engineering or exploration surveys, but methods also can be used for earthquake studies. Computational labs are provided for most chapters.

Presenting the mathematical and physical foundations of all EM methods, chapters include: numerical and analogue modelling, electrical properties and resistivity characteristics of geologic targets, basic principles of instrument design and detection of repetitive EM signals, and achieving the elusive goal of automatic interpretation of EM data.

A general reference for poststack seismic attributes it includes: theory, meaning, computation, and application; attribute maps and interval statistics; complex trace attributes; 3D attributes; seismic discontinuity attributes; spectral decomposition, thin-bed analysis, and waveform classification; poststack methods; and multiattribute analysis.

With case studies in all applications of engineering seismology, this book focuses on the application of the seismic method to geotechnical site investigations for buildings and infrastructures, landslide and active-fault investigations, and seismic microzonation. The broader scope includes exploration of earth resources and geothermal exploration.

Includes an overview of classical theory; early cornerstones from the 17th century and the works of Grimaldi, Huygens, and Young; details of the classical theory of diffractions as developed in the 19th century and reprinted works of Fresnel, Green, Helmholtz, Kirchhoff, and Rayleigh; cornerstones of modern theory; and appendices.

Seismic interpretation can be made simple and robust by integrating rock physics principles with seismic and petrophysical attributes bearing on properties of conventional and unconventional reservoirs. Practical solutions to interpretation problems in AVO analysis and inversion are addressed to streamline workflows in subsurface characterization.

From fundamentals to present AVO, it includes: Gassmann's equations and fluid substitution, Zoeppritz equations approximations, seismic amplitudes and processing considerations, interpretation techniques, the influence of anisotropy, the use of AVO inversion, the estimation of uncertainty, converted-wave AVO, and the future of the AVO method.

Covering seismic diffraction theory, modeling, observation, and imaging, the papers address key topics and include: overview; forward modeling; diffraction mathematical modeling techniques; physical modeling laboratory experiments; the observation of seismic diffractions in near-surface, reservoir, and crustal studies; and diffraction imaging.

Providing a practical guide for survey design, acquisition, interpretation, and application of microseismic hydraulic fracture monitoring, this text includes geologic and geomechanical factors that control fracture growth and discusses potential pitfalls and quality-control steps associated with collecting and interpreting microseismic data.

Covers the full range of gravity-exploration topics, including first principles, field instrumentation and operations, rock densities and density contrasts, data reduction, methods of interpretation, and geologic examples. The subject matter includes inversion and an appendix on the Fourier transform.

Intended for beginning interpreters, this book approaches seismic interpretation via synthesis of concepts and practical applications rather than through formal treatment of basic physics and geology. Based on the author's personal experience as a seismic interpreter, it is organised along the lines of notes from classes he designs and teaches.

Presents an analysis of seismic signatures for azimuthally anisotropic media and shows anisotropic inversion/processing methods for wide-azimuth reflection data and VSP surveys. The focus is kinematic parameter-estimation techniques; the prestack amplitudes section includes AVO and attenuation coefficients; field examples are included.

The reservoir-engineering tutorial discusses issues and data critically important engineers. The geophysics tutorial has explanations of the tools and data in case studies. Then each chapter focuses on a phase of field life: exploration appraisal, development planning, and production optimization. The last chapter explores emerging technologies.

This edition reflects evolution of the science, especially in engineering and production problems, 3D (including multicomponent) acquisition and processing, visualization, S- and converted waves, interpretation, anisotropy, AVO, geostatistics, geohazards, neural networks, tomography, downhole measurements, horizontal drilling, and deepwater work.

Expanding the author's original work on processing to include inversion and interpretation, and including developments in all aspects of conventional processing, this two-volume set is a comprehensive and complete coverage of the modern trends in the seismic industry - from time to depth, from 3D to 4D, from 4D to 4C, and from isotropy to anisotropy.

A thorough introduction to acquisition, processing, and interpretation, it includes: seismic wave phenomena in acoustic, elastic, and porous media; creating 2D and 3D images from field data; dip moveout, prestack migration, and depth migration; limitations of 3D seismic interpretation; and the role of attributes, impedance estimation, and AVO.
