Acoustic Full Waveform Inversion of DAS-VSP Data

Conclusion We developed a detailed processing workflow that is specifically designed for acoustic FWI and RTM of DAS-VSP data obtained from a deviated well. Field data typically contain numerous noises and shear wave interference. These noises can be attenuated effectively to ensure accurate acoustic FWI results. Our proposed methodology includes a multi-channel separation approach that enables extraction of uncontaminated P-wave data. This vital step improves the effectiveness and accuracy of subsequent FWI and RTM analyses.
