Abstract

This paper is a continuation of a previous one in which the author gave a comparison of several commonly used steep-dip seismic computing techniques on the basis of the horizontal displacements and depths of the reflection points they produce, assuming a rather "slow" parabolic increase of velocity with depth. In this paper, the comparison of these methods is extended to the case of a second and considerably "faster" velocity function and to the computation of a reflecting horizon through a fault zone. In addition, two other straight-path methods and three purely mathematical methods are introduced and compared in the same manner with the curved-path method.
