Abstract

Introducing a priori information in velocity model building is certainly one of the most challenging problems in seismic imaging. In this context, non-linear slope tomography, which expresses the velocity model-building problem as a multi-data multi-parameter optimization problem, appears particularly adapted for dealing with various types of constraints. With an application to the land Minagish dataset in Kuwait, we address here the problem of introducing information from wells into the velocity model-building problem. We show how short vertical wavelengths of the velocity at wells, which cannot be estimated by the inversion process, can be incorporated in the tomography update, resulting in a very accurate depth velocity model insuring both fitting at wells and focusing.
