Case Study: Advancing Seismic Imaging in Complex Geology
Steeply dipping layers and strong lateral velocity variations remain a major challenge in geophysical exploration. A recent study proposed an initial-model-constrained joint Kirchhoff prestack depth and time migration method โ integrating iterative velocity inversion, denoising, and model constraints to improve imaging fidelity and repeatability.
๐ Key results:
Sharper fault imaging and better diffraction focusing
Higher signal-to-noise ratio (S/N) and improved resolution versus conventional prestack time migration
Validated on both synthetic models and a real coalfield case (monocline 30โ35ยฐ, high-angle faults)
Field data were acquired using SmartSolo IGU-BD3C-5 broadband 3-component nodal seismometers โ 720 channels, 10 m ร 10 m CDP grid, max fold 52.
The method has been applied in coal mine safety, resource exploration, engineering investigation, and geohazard assessment.
