Abstract

This paper first developed a technique to tomographically estimate a Q model from the migrated image using two-way wavefield continuation method. When compared with the previous work with a one-way downward-continuation method, this technique exhibits better capability of handling the steep structure, e.g. the salt flank. Numerical results on a complex model with a salt body demonstrate the effectiveness of this two-way method on resolving the overturned wave propagation introduced by the steep structures.
