Elena Klochikhina | High-Resolution Angle Gathers with LSM
14 October | 10:35 - 11.00 CST (GMT-5). Iterative least-squares migration for high-resolution angle gathers.
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.
