Angle-dependent reflectivity by profile imaging

Jun Ji and Gopal Palacharla

Among the suite of prestack imaging methods available, profile imaging method is the most suited for providing wave-theoretical angle-dependent reflectivity estimates. In this study, we tested profile imaging method for its ability to preserve angle-dependent reflectivity on the image. A synthetic shot gather was generated by an elastic finite-difference modeling code (Karrenbach, 1992) for a shale and gas-sand model (Ostrander, 1982). The profile imaging was performed with phase-shift and finite-difference approaches.
