F031 Rock Physics and Depositional History from Seismic Matching – A Model Study S.A. Levin* (Halliburton Energy Services) U. Mello (IBM) V. Lopez (IBM) L. Xu (IBM) A.R. Conn (IBM) K. Scheinberg (IBM) & H. Zhang (IBM) SUMMARY In this study we apply advanced numerical optimisation techniques to extend the work of Imhof and Sharma (2005 2006) to integrate geological and geophysical data and infer the sedimentary parameters that produce a match to seismic data. In particular we seek to match not just event timing (phase) but also reflection strength (amplitude). This inverse problem of quantitatively matching present-day measurements of
