Factors Affecting Frequency Content in preSDM Imaging

E-07 FACTORS AFFECTING FREQUENCY CONTENT IN PRESDM IMAGING 1 IAN F. JONES and JUERGEN FRUEHN GX Technology EAME Lawrence House 45 High Street Egham Surrey TW20 9DP UK Abstract It is sometimes remarked that pre-stack Kirchhoff depth migrated images have a lower frequency content than their time-domain counterparts. Here we assess the various factors that influence frequency content during migration with the object of assessing the reasons for potential loss of bandwidth in migrated data. We demonstrate that there is no inherent reason for the bandwidth of Kirchhoff (or depth) migrated data to be worse than other migrated data and
