Summary:
I020 Imaging of Complex Structures of Salt Flank using Converted Waves on 3-C VSP Data Abstract 1 This paper presents a case study of a multifarious multi-component VSP survey in GOM using converted waves. The separated PP and PS reflections of the VSP data were migrated using a Vector 3C3D migration to image both the salt face and nearby sediment reflectors. The Vp/Vs ratio is estimated by matching dips of imaged reflectors with the structure dips. Both transmitted P-P and P-S converted waves were used to define the salt-interface by calculating salt exit points. Results from the multifarious VSP methods
