P011 FULL WAVEFORM INVERSION USING THE NONMONOTONE SPECTRAL PROJECTED GRADIENT METHOD NOAM ZEEV 1 OLGA SAVASTA 2 and DEBORA CORES 1 1 1 Universidad Simón Bolívar 2 PDVSA-Intevep Apdo. 76343 Caracas 1070-A Venezuela SUMMARY The Seismic Inversion problem is a large-scale optimization problem that has been solved using different optimization strategies that usually converge locally and get stuck in a secondary minimum. Since it is a large-scale problem computational efficient and low time consuming optimization techniques are also convenient. We proposed to solve the full waveform inversion using the nonmonotone spectral projected gradient method. The new methodology allows the objective
