Modeling of seismic wave propagation plays a key role in almost every aspect of exploration seismology. Fundamentally, it provides a means of understanding the character of recorded seismic data. Although analytical or semianalytical solutions exist

This is the first in a series of three papers focused on using variants of a logarithmic objective function approach to full waveform inversion. In this article, we investigate waveform inversion using full logarithmic principles and compare the resu

The recent advent of fast, inexpensive personal computers (PCs) is revolutionizing modern seismic depth imaging. Prices for supercomputer-style computation, graphical display, and data storage, halve every 18 months. Modern networking technologies co

Equivalent‐offset migration is a methodology for prestack‐Kirchhoff time migration that partially reverses the order of velocity analysis, normal moveout correction, stack, and migration. Though claimed to be computationally and analytically supe

It is quite common for mature North Sea fields to be producing significant volumes but infill drilling may be using maps made on survey data which is over a decade old. New acquisition has been common where the reservoirs are acoustically favourable

This paper focuses on the mapping of data from one surface geometry to another. The primary tools under study are azimuth moveout (AMO) and Kirchhoff data mapping (KDM). By comparing the AMO methods populairced by A. Canning and G. F. Gardner and Bio

In this presentation we discuss seismic processing on a Sony-IBM-Toshiba PlayStation III (PS3) cluster. Rather than focus on only one computationally intensive algorithm, we discuss various aspects of the more popular seismic imaging algorithms. We d

SUMMARY Current production-grade-wave-equation migration technology is almost totally based on one-way methods. These methods are typically derived through an asymptotic approximation of the square root of a one-way propagator derived by factorizatio
