A Review of 3D Vectorial True Amplitude Prestack Migration of Converted S-Waves

A06 A REVIEW OF 3D VECTORIAL TRUE AMPLITUDE PRESTACK MIGRATION OF CONVERTED S-WAVES Introduction 1 Processing of converted modes requires specific algorithms that take count of their particular kinematics. Recently a great attention has been paid to prestack isotropic and anisotropic time migration approaches. However the applicability of time domain processing to C-wave is much more restricted than it is for P-wave since any lateral velocity variations impacts the conversion point location. Hence there is a great need for C-wave dedicated depth imaging workflow. In this paper we develop some key aspects related to the imaging of 3C converted waves
