Session: SPMI 1 Least Squares Migration and its Application

Authors: Lian Duan (formerly of PGS), Alejandro Valenciano (formerly of PGS), Nizar Chemingui, and Elena Klochikhina, PGS.

Elena Klochikhina presents a pre-stack, data domain LSM implementation that provides high-resolution angle gathers, correcting for angle-dependent illumination effects, and therefore providing more reliable amplitudes for AVA analysis.
