Converted-wave prestack depth imaging with the nonstationary wavefield extrapolators

Yanpeng Mi and Gary F. Margrave


The PSPI dual extrapolation algorithm is applied to converted-wave prestack depth imaging. The 1997 Blackfoot 3C-2D data is used for the testing purpose. Both the P-P and P-S data were migrated and compared. The resulting P-P and P-S reflectivity images are very clear, except for edge effects, and they tie reasonably well in depth.
