Pre-Stack Depth Migration Workflow for Converted Waves

P107 PRE-STACK DEPTH MIGRATION WORKFLOW FOR CONVERTED WAVES Summary We present a pre-stack depth migration (PSDM) workflow for converted waves. This flow is equivalent to that for compressional waves with a few modifications. We use synthetic data to demonstrate that this workflow produces PS images that are consistent with PP images. Introduction The advantages of using converted-wave data in exploration and reservoir characterization include imaging through gas clouds (e.g. Valhall field Thomsen et al. 1997) and imaging of sands with low P-wave impedance contrasts (e.g. Alba field MacLeod et al 1999). In addition simultaneous analysis of PP and PS data
