Depth velocity model building remains a difficult step within the seismic depth imaging sequence. Stereotomography provides an efficient solution to this problem but was limited until now to a picking of seismic data in the prestack time un-migrated

SUMMARY We present the extension of stereotomography to P- and S-wave velocity estimation from PP- and PS-reflected/diffracted waves. In this new context, we greatly benefit from the use of locally coherent events by stereotomography. In particular,

Most methods for velocity macromodel estimation require considerable operator input, mainly concerning the regularization and the picking of events in the data set or in the migrated images. For both these aspects, slope tomography methods offer inte

Seismic information may be used for reservoir model updates, but typically only in a qualitative fashion. Whilst quantitative use of time-lapse seismic data may significantly improve model updates, it remains a challenging under-determined problem. H

Data quality is an important issue in seismic data processing. In this context ocean bottom nodes are particularly interesting. 4-component nodes are plugged in the sea bottom by a remote operating vehicle and record the seismic vector wave field. As

SUMMARY In Kirchhoff based migration, the relevant information is located at the specular reflection point along the migration operator. Limiting the migration operator around this specular point not only increases the speed of the process but also i

Stereotomography, as a slope tomography method, requires the knowledge of the slopes in both common source and common receiver panels to constrain the velocity model. In case of nodes data, where individual receivers are set down to the sea floor, th
