C028 Simultaneous Frequency-Domain Seismic Full- Waveform Data Inversion W. Hu* (Schlumberger-Doll Research) A. Abubakar (Schlumberger-Doll Research) & T. Habashy (Schlumberger-Doll Research) SUMMARY We employ an inversion algorithm based on the constrained Gauss-Newton method (Habashy and Abubakar 2004) to solve the nonlinear optimization problem. The forward model is based on a finitedifference frequency domain (FDFD) method combined with the perfectly matched layer (PML) absorbing boundary condition (Bérenger 1994). Two different regularization schemes the L2-norm and the weighted L2-norm (van den Berg and Abubakar 2001) are used to overcome the ill-posed nature of this problem. The regularization parameter is chosen automatically using
