Abstract

The method described in [1] is applied to a real model of a reservoir top. Selected results from a survey involving normal rays joining a reflector to an array of linear profiles are presented. The overburden involves 4 interfaces at which the rays are transmitted. Small-scale oscillations of the reflector generate some fifty caustics in the reflected field. For each receiver there are up to fifty normal rays joining it to the reflector. Iterative two-point ray tracing requires guessing an appropriate starting approximation at least once for each branch [2]. In the vicinity of a caustic, where two branches join, convergente is poor. These problems are overcome by point-to-curve ray tracing.
