Abstract
One key to model-based depth imaging procedures is the ability to work flexibly in the three principle seismic domains; migrated time, unmigrated time and depth. The observations and analyses performed in each of these domains play a distinct role in creating an earth model accurate and robust enough to yield a suitable depth image tor exploring in the complex and subtie structure environment.
