Initial Results

One-way Riemannian wavefield extrapolation (RWE) on computational meshes conforming to the direction of turning-wave propagation is an alternative forward-modeling procedure for waveform inversion. Forward-modeling tests demonstrate that the RWE approach may be a sufficiently accurate approximation for calculating the wavefield phases important for early-arrival waveform inversion. Initial results indicate that RWE waveforms are well matched at wide offsets to finite-difference data, and can be used in a waveform inversion scheme to invert synthetic data for moderate 1D velocity perturbations.
