Enhanced Seismic Imaging in the Midland Basin with Multiparameter Full-Waveform Inversion

We introduce a multiparameter full-waveform inversion (FWI) approach for land seismic imaging that jointly estimates subsurface velocity and reflectivity. The method employs a scale-separation strategy to recover background velocity and high-resolution reflectivity, extending imaging beyond the depth limits of head and diving waves. To enhance robustness against noise and low-frequency limitations, we incorporate a dynamic matching objective function that aligns observed and modelled phases through multidimensional correlation, reducing sensitivity to amplitude mismatches and low signal-to-noise ratios. The reflectivity kernel further improves high-wavenumber content, delivering superior resolution and structural coherence compared to conventional imaging. Application to a Midland Basin land dataset demonstrates the method’s potential for high-resolution imaging in complex geological settings.
