3-D migration velocity analysis with kinematic Kirchhoff migration
نویسندگان
چکیده
Migration velocity analysis includes both depth-focusing analysis and residual curvature analysis of coherency panels. In either method, it is widely used for 2-D velocity analysis in regions of complex geological structures. Unfortunately, since complex structures tend to be 3-D structures, 3-D prestack depth migration is desirable. The most commonly proposed candidate is kinematic Kirchhoff migration. This paper describes how we can use it as a datuming-migrating tool, to produce migration velocity analysis panels in 3-D seismics.

3-D wave-equation imaging of a North Sea dataset: common-azimuth migration + residual migration
3-D prestack common-azimuth depth migration (CAM) has strong potential for accurately imaging complex media and correctly handling multi-pathing. Here, we apply the technique to a North Sea dataset recorded over a salt dome region. The results obtained demonstrate the suitability of the method for complex media, and illustrate important differences with Kirchhoff methods. A detailed analysis of...
متن کاملShort Note Common-azimuth migration and Kirchhoff migration for 3-D prestack imaging: A comparison on North Sea data
Common-azimuth migration (CAM) is a 3-D prestack depth migration technique based on the wave equation (Biondi and Palacharla, 1996). It exploits the intrinsic narrow-azimuth nature of marine data to reduce its dimensionality and thus manages to cut the computational cost of 3-D imaging significantly enough to compete with Kirchhoff methods. Based on a recursive extrapolation of the recorded wav...
متن کاملSubsalt imaging by common-azimuth migration
The comparison of subsalt images obtained by common-azimuth migration and singlearrival Kirchhoff migration demonstrates the potential of wave-equation migration when the velocity model causes complex multipathing. Subsalt reflectors are better imaged and the typical Kirchhoff artifacts caused by severe multipathing disappear. A detailed analysis of common-azimuth images indicates that the resu...
متن کاملApproximate analytical formulas for Kirchhoff migration operator
Two important tools in seismic processing––Kirchhoff migration and demigration operators––are the basis for many imaging problems solution. Due to high numerical and computational requirements, the use of those tools for three dimensions are very computation-costly. This fact has motivated us to investigate Kirchhoff migration operations for simpler types of media in order to provide faster res...
متن کامل3-D wave-equation prestack imaging under salt
For the SEG-EAGE salt data set, common-azimuth migration produces better images in the subsalt than single-arrival Kirchhoff migration, at a similar computational cost. Subsalt reflectors are better imaged and the typical Kirchhoff artifacts caused by severe multipathing disappear. We show how angle-domain Common Image Gathers (CIG) can be easily extracted from prestack wavefield downward conti...
