Abstract

We develop an integrated velocity model building workflow for prestack depth imaging in onshore settings with a complex shallow subsurface. This workflow incorporates dispersion curve inversion and full waveform inversion into a single framework to optimize the advantages of each. An accurate near-surface velocity is derived using the dispersion curve inversion technique that overcomes limitations of traditional traveltime tomography. This velocity is then incorporated into layer-stripping full waveform inversion. We illustrate the workflow on an experimental data set from Inner Mongolia, whose long-offsets and low-frequency content provide the necessary input for both the dispersion curve and full waveform inversion techniques.
