Enhanced Seismic Imaging with LAD-Based LSM: A Case Study

Summary This article presents an image-domain Least-Squares Migration (LSM) technique that uses high-resolution Point Spread Functions (PSFs) derived from Local Angle Domain (LAD) illumination data. The method enhances migrated seismic images by improving resolution and amplitude fidelity without full data reprocessing. Applied to the Volve OBC dataset, the approach demonstrated improved high-frequency content and clearer fault continuity, confirming its effectiveness in structurally complex settings.
