Abstract
We present a new imaging methodology based on the depth extrapolation of a single dataset obtained by randomly compressing sources and shot-gathers. In this work a Monte Carlo imaging condition was implemented with a Phase Shift Plus Interpolation (PSPI) extrapolating kernel and tested on the SEG-EAGE salt model. This study demonstrates that wavefield 3D prestack depth migration is possible for industrial applications, providing high quality results in reasonable computational times.
