Abstract

P322 Frequency Response Modeling of Seismic Waves Using Finite Difference Time Domain with Phase Sensitive Detection (TD-PSD) K.T. Nihei* (Chevron Energy Technology Co.) & X. Li (Lawrence Berkeley National Laborator) SUMMARY We examine an alternative approach for computing the frequency response of a heterogeneous anisotropic viscoelastic medium. The approach consists of running an explicit finite difference time domain (TD) code with a harmonic wave source out to steady-state and then extracting the magnitude and phase from the transient data via phase sensitive detection (PSD). The PSD algorithm requires integration over a single cycle of the waveform to obtain accurate phase
