SEISMIC DATA TRAINING COMPRISING MULTIPLE PREDICTION USING TIME REVERSE MIGRATION WITHDRAWAL

摘要

Methods and systems for generating a stable inverse time migration (RTDM) removal equation for predicting wave phenomena, such as reflections, refractions and multiples, are described. A coupling term is added to an RTDM equation and a reflectivity associated with the coupling term is replaced by a pseudo-density function deduced from a nonlinear equation. The resulting coupled and stabilized RTDM equation is then used to predict the desired wave phenomena based on the applied seismic image.
