Abstract
P008 True amplitude Gaussian beam imaging Abstract 1 We present an original approach of true amplitude seismic imaging by means of weighted summation of multi-shot multi-offset data. These weights are computed by Gaussian beam (GB) tracing from current points within target area towards acquisition system. The special choice of GB provides possibility to take into account both illumination conditions and structure of covering layers. Global GB regularity allows person to be not care of caustics and foci locations and to use uniform relations through the target area and overburden layers. Introduction. Our aim is to image scatterers/reflectors in the Earth
