Book Synopsis True Amplitude Kirchhoff Migration by : Thomas Hertweck
Download or read book True Amplitude Kirchhoff Migration written by Thomas Hertweck and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An important task in seismic reflection imaging is to estimate subsurface structures from the prestack data. This means that the reflection events in the recorded data have to be transformed into images in the depth domain, the reflectors. A geometrically appealing approach for the corresponding process is Kirchhoff migration which is based on an integral solution of the wave equation. Applied in its original purely kinematic form, this process provides a structural image of the target region under investigation. However, Kirchhoff migration is also able to handle the amplitude-related aspects of wave propagation, thus allowing to assign physically sound amplitude values to reflector images. In such a true-amplitude migration, the geometrical spreading effects are removed from the input data during the imaging process and, thus, reflector amplitudes become basically a measure of the angle-dependent reflection coefficient. Commencing with the basics of wave propagation and ray theory, a complete description of Kirchhoff migration is presented. By relating the strict mathematical derivation of true-amplitude Kirchhoff migration to clear geometrical concepts, the gap between the originally graphical migration schemes and the nowadays available analytical descriptions based on a stationary-phase evaluation is closed. Further aspects relevant to the correct recovery of amplitudes in depth migration, such as the handling of topography and irregular geometries, are explained in a mathematical as well as in a geometrical manner. Finally, Kirchhoff migration is integrated into a seismic reflection imaging workflow based on the data-driven common-reflection-surface (CRS) stack method.
Book Synopsis Seismic Imaging and Inversion: Volume 1 by : Robert H. Stolt
Download or read book Seismic Imaging and Inversion: Volume 1 written by Robert H. Stolt and published by Cambridge University Press. This book was released on 2012-02-09 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory, and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

Book Synopsis Seismic Amplitude Inversion in Reflection Tomography by : Yanghua Wang
Download or read book Seismic Amplitude Inversion in Reflection Tomography written by Yanghua Wang and published by Elsevier. This book was released on 2003-02-25 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book of its kind on seismic amplitude inversion in the context of reflection tomography. The aim of the monograph is to advocate the use of ray-amplitude data, separately or jointly with traveltime data, in reflection seismic tomography.The emphasis of seismic exploration is on imaging techniques, so that seismic section can be interpreted directly as a geological section. In contrast it is perhaps ironic that, in decades of industrial seismology, one major aspect of waveform data that potentially is easier to measure and analyse has generally been ignored. That is, the information content of seismic amplitudes. Perhaps the potential complexity has deterred most researchers from a more thorough investigation of the practical use of seismic amplitude data. The author of this volume presents an authoritative and detailed study of amplitude data, as used in conjunction with traveltime data, to provide better constraints on the variation of seismic wave speed in the subsurface.One of the fundamental problems in conventional reflection seismic tomography using only traveltime data is the possible ambiguity between the velocity variation and the reflector depth. The inclusion of amplitude data in the inversion may help to resolve this problem because the amplitudes and traveltimes are sensitive to different features of the subsurface model, and thereby provide more accurate information about the subsurface structure and the velocity distribution. An essential goal of this monograph is to make the amplitude inversion method work with real reflection seismic data.
