P043 Transformation Noise Suppression for Transmitted Wave VSP Imaging N. Marmalevskyi* (Ukrainian State Geological Prospecting Institute) Y. Roganov (Ukrainian State Geological Prospecting Institute) A. Kostyukevych (Tesseral Technologies Inc.) & Y. Glozhyk (Kyiv National Taras Shevchenko University) SUMMARY Down going waves are used for seismic imaging in the near-well area additional to the reflected waves. For down going imaging the transmitted converted waves are used most often. Migration on transmitted converted waves enables obtaining images of the velocity discontinuities which have not been presented in the velocity macro-model used for imaging. If the sizes of such discontinuities are commensurable with a
