Fourier finite-difference migration of prismatic waves for steeply dipping structure imaging with dip-guided amplitude-matched fusion

Accurate imaging of steeply dipping structures is critical for hydrocarbon reservoir identification and fault characterization in complex regions. However, conventional imaging methods based on primary reflections often fail to resolve near-vertical and overturned interfaces due to limited acquisition aperture and su...

A Supervised U‐Net With Diffusion Prior Regularization for Efficient Seismic Diffraction Separation

Seismic diffraction events contain high‐wavenumber information that is critical for imaging small‐scale discontinuities, yet their weak amplitudes are often obscured by strong reflection energy. Diffusion models offer a powerful framework for diffraction separation, but their iterative reverse‐diffusion sampling is com...
