DSO Velocity Inversion: A "Gas Cloud" Synthetic Example
A low velocity near surface anomaly delays the seismic wavefield and focuses wavefronts passing through it. Such anomalies occur as a result of localized gas seepages ("gas clouds") in the sedimentary column, for example. Use of a migration velocity model not containing the anomaly will produce images containing false synclinal structures. Application of DSO velocity inversion to a simple example of this type images the velocity anomaly and removes the false structure.
