WebPlane-wave depth migration. We present fast and efficient plane-wave migration methods for densely sampled seismic data in both the source and receiver domains. The methods are based on slant stacking over both shot and receiver positions (or offsets) for all the recorded data. If the data-acquisition geometry permits, both inline and crossline ... WebAug 1, 1998 · Anisotropic depth migration (ADM) honors Snell's Law, as does isotropic depth migration. It also accounts for wave front bending, due to direction of propagation relative to the bedding planes of the formations. Consider for a moment the sensitivity of depth migration to velocity.
WebAnisotropic depth migration reduces the overall depth error on a depth migrated section by removing a systematic anisotropy error from our data. We can then use the well depths to calibrate our anisotropic velocity model to simultaneously …
