Improved Amplitude Multi-One-Way Wave-Equation Migration

F047 IMPROVED AMPLITUDE MULTI-ONE-WAY WAVE EQUATION MIGRATION Abstract 1 The migration algorithm based on improved amplitude multi-one-way modeling method is presented. The multione-way method allows to take into account the errors due to the factorization of the two-way wave equation by downgoing and upgoing one-way equations. The migration is based on a modified Claerbout imaging principle. Synthetic examples demonstrate the interest of the multi-one-way migration to better recover the amplitudes. Introduction Currently one-way wave equation migration algorithms are widely used for imaging over complex geological structures because of their advantages in comparison with ray-based Kirchhoff migration when multipathing of seismic
