Kirchhoff Modeling via Wave Equation Datuming.

Abstract

The acoustic reflection response of a plane wave on a cylindrical surface is calculated from a specialization of the Kirchhoff integral. Computational advantages are obtained by assuming that structural changes occur only along the direction of data collection. Off-line geologic invariance permits an integral to be replaced by a short convolution operator. The restriction to single interface modeling permits implementation of personal computers. Also, the single layer algorithm provides the framework for a multilayer code. Details on implementation, example executions, and program listings are included. Originator-supplied keywords include: Kirchhoff modeling, Wave equation Datuming, Rayleigh II integral, Data continuation, and Velocity replacement.
