Abstract
The need for robust 3D model-building technology and methodology to support 3D prestack imaging is weIl recognised within the seismic processing industry. What has received relatively less attention is a) development of techniques which maximise the value of the conventional 3D processing sequence; and b) critical evaluation of the performance of the ray trace algorithms which generate the traveltime tables for the prestack migration "engines". Enhancements in these two areas are considered essential components in the creation of an economically viabIe 3D pre-stack processing product. In this paper we present a case history which specifically examines these issues.
