The problem of velocity estimation and its relationship with AVO

AVO analysis requires previous prestack migration of the data, and velocity estimation is a key factor for this imaging problem. Velocity estimation affects AVO response because it modifies the position of the events and the resulting amplitude values Grubb and Tura (1997). On the other hand, because of the difficulty of estimating velocity models in complex areas, is it important to understand the sensitivity of AVO attributes to variation in velocity models.

The aim of the work described in this report is to find any relation between AVO-related seismic attributes and velocity uncertainty that could be used to generate confidence measures for AVO inversion, and to support the imaging problem by discriminating between different velocity models from AVO-related attributes.
