Summary:
B-08 3D STEREOTOMOGRAPHIC INVERSION ON REAL DATA SET Abstract 1 EMANUEL CHALARD 1 3 PASCAL PODVIN 1 SOAZIG LE BEGAT 1 PHILIPPE BERTHET 2 BERNARD DAVID 3 Stereotomography is a new tomographic method introduced in 2D by Billette and Lambaré (1998). It uses the apparent slopes of locally coherent seismic events picked in the prestack data cube to constrain the velocity model. In previous papers (Chalard et al. 2000a 2000b) we introduced the extension of stereotomography to 3D. In particular we proved that in the case of multi-streamer marine data acquisition the picking of seismic events can be performed independently
