Topographic Correction Using CRS Parameters

P165 TopographiccorrectionusingCRSparameters Abstract V. Grosfeld R. Biloti L. T. Santos and M. Tygel State University of Campinas Dept. Applied Mathematics P.O. Box 6065 13081-970 – Campinas – SP Brazil The Common-Reflection-Surface (CRS) method is a stacking process that simulates a zero-offset section and produces useful traveltime attributes from multi-coverage seismic data. In this paper we show that the CRS can be also applied to non-horizontal measurement surface giving rise to a zero-offset along surfaces with topography. Moreover the obtained CRS attributes can be used for redatuming the section to a selected horizontal datum. A synthetic example is provided to illustrate
