Abstract

Summary

In the past the seismic industry has made large investments in the removal of multiples from the seismic response ('data linearization'), with the purpose to make the data suitable for our linear velocity estimation and linear migration algorithms. Now we are beginning to understand that multiples contain most valuable information that should not be removed.

Instead they should be utilized, making velocity estimation and migration fully consistent with the underlying physics. In this presentation it is shown that velocity estimation can function as an integral part of the nonlinear migration process: Joint Migration Inversion (JMI).

It is also shown that JMI is insensitive to the initial velocity distribution.
