Smoothing the Marmousi model for Gaussian-packet migrations

Ludek Klimes

Summary

Construction of a smooth velocity model by smoothing gridded velocities of the "Marmousi model and dataset", using the Sobolev scalar products, is discussed. The smooth velocity model is prepared so as to be suitable for ray tracing and for Gaussian-packet migrations.

Keywords

Model specification, smoothing, objective function, Sobolev scalar products, ray methods.
