C006 From Time to Depth Imaging – A Fast and Accurate Workflow G. Lambaré (CGG) P. Herrmann (CGG) J.P. Touré (CGG) L. Capar (CGG) P. Guillaume* (CGG) N. Bousquié (CGG) D. Grenié (CGG) & S. Zimine (CGG) SUMMARY We present a new strategy for depth velocity model building from pre-stack time migrated gathers (PreSTM). It is based on dense volumetric dip and residual move-out picking in the PreSTM domain. The kinematic information is de-migrated to compute multi-offset un-migrated attributes - called seismic invariants - used as input data for a multi-offset depth tomography. Compared to the corresponding existing strategy based
