Front Matter. Preview Abstract The front matter contains the title page, copyright page, table of contents, and preface. Preview Abstract 1. This is unfortunate because equations are simply compact, quantitative expressions of relationships, and one should make an effort to understand the information that they convey.
Theory of Seismic Waves. Partitioning at an Interface. Preview Abstract When a wave is incident at the interface between two solid media, four boundary conditions must be satisfied continuity of normal and tangental displacements and stresses.
The velocities are determined by the densities and elastic constants while the Geometry of Seismic Waves. Preview Abstract Where the velocity is constant, raypaths are straight lines. In Figure 4. The image point I or virtual Seismic Velocity. Characteristics of Seismic Events.
Preview Abstract A wave is coherent when it appears on successive traces in a systematic way and with approximately the same waveshape. Apparent-velocity filtering , also called apparent-dip filtering , refers to discrimination attenuation based on the slope of a linear Seismic Equipment.
Preview Abstract Radio-navigation methods are used to determine distances in marine surveys and the velocity is generally assumed to be that over saltwater. Reflection Field Methods. Preview Abstract 8. The connections to plugs at each end of the section effectively rotate the system by the number of groups to be connected to the section.
Thus, if Data Processing. Preview Abstract If g t is a periodic function , that is, one that repeats exactly at intervals T called the period and has a finite number of maxima, minima, and discontinuities in each interval T , then it can be expressed in a Fourier series in any one of the three Geologic Interpretation of Reflection Data. Sonic logs usually display slowness or specific transit Refraction Methods. Preview Abstract Early seismic prospecting for salt domes involved locating geophones in different directions from the source at roughly the same distance from it.
In terms of the volume of data, seismic exploration is dominated by work on the continental shelf and in recent years there has been a steady trend towards exploration in deeper waters.
The first edition of Exploration Seismology appeared in two volumes in and It was soon widely recognized as the most comprehensive text covering the whole field and has served as an invaluable resource for both students and practicing geophysicists. Since the publication of the first edition there have been many improvements in seismic exploration.
Advances in acquisition and computer technology have yielded dramatic increases in the quantity and quality of seismic images. Threedimensional reflection surveys are now routinely used to delineate known hydrocarbon reservoirs and many specialized techniques are receiving increased interest. In the preface to the second edition, the authors state that they "want this book to be a reference work as well as a text book and guide for practicing geophysicists".
These are ambitious and sometimes contradictory objectives and yet in virtually all respects the book succeeds splendidly. Not only has the new edition been comprehensively updated to reflect recent developme:ats but new material has been added elsewhere and the order of presentation improved.
