Kinematic artifacts in the extended subsurface offset domain
We provide a kinematic analysis of the prestack image behaviour in the subsurface offset domain. When the medium properties are perfectly known, the image is expected to focus at the zero subsurface offset, where the incident and the scattering wavefields interact at a common point. However, kinematic artifacts are often observed in subsurface offset common-image gathers (CIGs) away from the ze...
متن کاملAnalysis of converted-wave extended images for migration velocity analysis
Converted-wave data have been recognized to have potential in complementing conventional compressional data. However, imaging for converted-waves is more difficult mainly due to the need for estimating shear-wave velocities, in addition to compressional-wave velocities. The common practice is to obtain the shear-wave velocity by registering PS and PP images. Despite its low cost, this procedure...
متن کاملDip-angle decomposition in relation with subsurface offset extended wave-equation migration
Our proposal provides post-migration techniques for computing angle-domain common-image gathers (CIGs) from seismic images, extended by the subsurface offset, in relation with wave-equation migration methods. In addition to the commonly used decomposition of the scattering-angles, we associate the wave-equation migration with dip-domain image gathers as well. Our methodology suggests a system o...
متن کاملScattering and dip angle decomposition in relation with subsurface offset extended wave-equation migration
An angle-dependent reflection coefficient is recovered by seismic migration in the angle-domain. We propose a post-migration technique for computing scattering and dip angle common-image gathers (CIGs) from seismic images, extended by the subsurface offset, in relation with wave-equation migration methods. Our methodology suggests a system of Radon transform operators by introducing local trans...
متن کاملWave-equation migration velocity analysis using extended images
Wave-equation migration velocity analysis (WEMVA) is a velocity estimation technique designed to invert for velocity information using migrated images. Its capacity for handling multi-pathing makes it appropriate in complex subsurface regions characterized by strong velocity variation. WEMVA operates by establishing a linear relation between a velocity model perturbation and a corresponding mig...
